Definitions

  • the invention relates to an electrical circuit breaker, in particular a circuit breaker for low voltage.
  • the breaking capacity and the turn-off time of a circuit breaker when a fault current occurs depend on various parameters.
  • the switch-off process consists of the tripping time, the proper time and the switch-off time.
  • the tripping time is the time from the occurrence of the tripping causing magnitude to the initiation of the tripping operation, for example the unlatching of a switching mechanism. This is followed by the proper time of the switch, which is due to the dynamic processes of the moving and opening contacts of the switch. With a switch for the higher power range (rated current up to 100 kA) one expects a turn-off time of about 50 msec.
  • short-circuiters are used to switch off arcing faults in electrical systems.
  • different detection systems for physical effects of the burning arc can be used.
  • a proven system is based on the optical detection of an arc ( EP 0575 932 B1 ).
  • a pyrotechnically driven short circuiter EP 1052 665 B1 or WO 200062320 A1
  • through one via thyristors short circuit to be switched DE 4438593 A1
  • a vacuum interrupter DE 4404074 A1
  • An arc detection and extinguishing system thus consists of detection means, a short-circuiter and associated electronic switching means.
  • a short circuit breaker is connected in parallel with the circuit breaker, such that further bus bar elements are arranged on the busbar connections of the circuit breaker, at the ends of which the short circuiter is positioned.
  • the quality, in particular the cross section of the busbar elements must correspond to those busbars with which the circuit breaker and the electrical system are supplied. This means that a considerable amount of material has to be used for the "passive" short-circuiter, which is intended only for the rare case of an arc fault. Therefore, the length of the busbars to be used for the connection of the short-circuiter is selected to be as short as possible, so that the short-circuiter is in relatively close proximity to the circuit breaker.
  • the busbars flowing through the load current and the circuit breaker heat up due to the current heat and get an increased operating temperature.
  • the increased operating temperature is also communicated to the short-circuiting device via the highly conductive connection rails.
  • short-circuiters especially those designed as pyrotechnic short-circuiters, have a thermal load limit.
  • a pyrotechnic generator may not be operated above a continuous temperature of 85 ° C.
  • To exclude a thermal load is used in the assembly of pyrotechnic short-circuiters clamped on the connection rails heat sink.
  • the use of cooling elements is also an additional cost of materials.
  • the invention is therefore based on the object to provide measures in a circuit breaker, which is associated with a reduction of material costs and allows over the normal function of the circuit breaker accelerated shutdown of a short circuit.
  • a short-circuiting device is arranged at least on the load side of the circuit breaker on the power connection rails for establishing a short circuit between the busbars in a fault current detected by a fault current detection unit.
  • a fault current a short circuit or a burning arc fault can be detected and turned off.
  • a short-circuiter can also be formed on the network side of the circuit breaker.
  • a tension lever system can be used, in which - without screwing - the short-circuiter is fixed with a tight fit on the power supply rails.
  • threaded bolts are arranged on the connection busbars of the circuit breaker, which correspond with connection points in the short circuiter, where, for example, bores are present, which are slidable over the threaded bolts. The attachment is then done with screws (possibly with washers).
  • the typical use of a short circuiter will be the arrangement on the load side of the circuit breaker.
  • the short-circuiter between circuit breaker and the underlying electrical system for example, switching or distribution station transformer station, electric motor
  • disconnects the system in a short circuit from the grid for example, switching or distribution station transformer station, electric motor
  • a short-circuiter can also be introduced on the network side of the short-circuiter.
  • two short-circuiters can also be present: one in front of and one behind the circuit breaker.
  • the use on the line side of the circuit breaker has the advantage that the entire connection area (transformer, cable, rails) 'in front of the circuit breaker' is in the monitoring zone of the short circuiter.
  • an activated short-circuiting device deletes the arc fault and the upstream, higher-level infeed protection switch drops the 'task' to switch off the existing short circuit. It may also be provided for optimizing the system that an arc fault detection unit is installed in the connection area, via which a switching signal to the short-circuiter can be transmitted.
  • the arrangement according to the invention allows the circuit breaker to be fully operated, regardless of whether the short-circuiting device is in function (armed) or disabled (but not short-circuited).
  • the short circuiter should always be accessible from the outside.
  • An installed short-circuiter should be lockable for security reasons.
  • a flap or a lid may be present.
  • electrical contact means which are suitable for receiving arranged on the short-circuiting electrical counter contact means.
  • About the contact means of the short-circuiting is controlled by the circuit breaker, or by an electronic module formed in the circuit breaker.
  • the electrical contact means (such as plugs and sockets) are automatically coupled when inserting the short-circuiting in the insertion shaft.
  • About the contact means electrical performance data, working variables, settings and / or trip signals between circuit breaker and short circuiter can be transmitted.
  • the circuit breaker may have a lock against the reclosing of the circuit breaker that occurs after triggering the switching function in the short circuiter in function.
  • short circuiters As mentioned in the introduction, various types and types of short circuiters are known. A suitable for the particular purpose short circuiter will be able to determine and select the expert. Preferably, a pyrotechnically driven short circuiter is recommended. To drive a nitrocellulose-based chemistry may be provided. The connection rails in the short-circuiter form a sandwich-like package. The pyrotechnic drive drives a metallic bolt through the stack of connecting rails, so that the phases are mechanically contacted with each other within less than 1 msec and a short circuit is generated. In a situation where the short circuit is a burning arc, the arc is deprived of energy and extinguished.
  • the short circuiter should short circuit at least two phases of the power connection. It is also discussed in professional circles, the short circuiter for contacting at least one phase of the power connection to ground (set up for switching to PE). Both embodiments can be used.
  • the circuit breaker is - as usual - equipped with a detection electronics for detecting a fault current on the load side in at least one phase.
  • a current transformer may be present, which is provided for detecting a load-side fault current in one of the phases.
  • the operating state of the short-circuiter is maintained by an energy store (for example, by a capacitor bank) whose stored energy is sufficient for the actuation (ignition) of the short-circuiting drive.
  • the charge of the energy storage should be permanently available. Therefore, it is advantageous if there is a permanent power supply for the energy store. This should be independent of the grid on which the electrical system and the circuit breaker are located.
  • the power supply can be designed battery-backed or from a supply from a parallel electrical network. In a battery-powered variant, care must be taken to ensure that the battery always has the full charge state, which is most easily done by means of automatic charge monitoring.
  • circuit breaker according to the invention is possible in virtually all common control cabinets of electrical systems.
  • the circuit breaker short-circuiter combination is a compact unit. An additional space requirement does not exist.
  • the circuit breaker according to the invention can be replaced by existing switching systems in a retrofit process.
  • the circuit breaker and short circuit conductor conductors and busbars should be rated for a short circuit current in excess of 100 kA for a period of up to 500 ms. With this specification, it is possible under certain designs of the electrical system to reduce the criteria for their short circuit strength for the system. Previously, it was assumed that busbars, rail supports and other live parts of an electrical system for a maximum expected short-circuit current should be upgraded. When using the circuit breaker-short-circuiter combination, the short-circuiter switches off the electrical system within 2 msec. The short-circuit load of the system is thus minimized. An otherwise existing requirement for an electrical system for maximum short-circuit strength therefore no longer has to be fully met. Of course, this has economic advantages for the plant operator.
  • Another advantage is that the switching function of the circuit breaker is shortened.
  • the full short-circuit current occurring directly in the circuit breaker is detected by the short-circuit release.
  • Magnetic short-circuit triggers receive the tripping energy from the perturbing source itself and 'react' according to the magnitude of the current.
  • an arc fault represents a damped short circuit because the arc fault voltage drops across a finite ohmic resistance.
  • circuit breakers have a turn-off time of up to 50 msec. Circuit breakers are designed so that they can be loaded with the full short-circuit current during this time. The stronger short-circuit current leads to an accelerated reaction of the short-circuiter, and thus to a shortening of the switch-off time of the circuit breaker. It comes almost to a lowering of the voltage level for short circuit. The load duration shortens itself. It comes to a relief of the circuit breaker for maximum switching loads.
  • the illustrations in the figures show a circuit breaker 10 designed as a circuit breaker, which is located in front of an electrical load 40 in a three-phase (L1, L2, L3) network.
  • the circuit breaker has at least one detection unit (short-circuit release) and an overload release.
  • the latter can be designed as a bimetallic trigger. Overload triggers work delayed with the occurrence of a high, presettable current and cause the opening of the contacts of the circuit breaker via the switching mechanism 16.
  • the intended detection unit 20 is present as an electronic unit, which is controlled by current detection means 21.
  • current detection means current transformer, such as Hall sensors can be provided.
  • the circuit breaker-short-circuiter combination is that at least one attachment point, a short-circuiter is present.
  • FIG. 1B there is space on the load side LS of the circuit breaker in which a short-circuiting device is installed.
  • the bus bars 12 of each phase L1, L2, L3 are accessible and provided with means 32 (here threaded bolts) for releasable installation (contacting, attaching, connecting, screwing) of the short-circuiter 30.
  • the network-side busbars 12 phases L1, L2, L3 can be short-circuited with one another.
  • an insertion shaft 14, 14 ' is present.
  • the housing of the circuit breaker is - according to figure representation - formed with an integrated insertion shaft.
  • the short-circuiting device is designed in terms of design and geometry so that it is adapted to the housing of the circuit breaker, or the insertion shaft. It can be dispensed with a separate housing design of the circuit breaker, if an insertion shaft is not considered necessary. It must be provided alone that the short-circuiter 30 in any form on the power supply rails fastened (flanged) is.
  • buttons are available, which may be present in the usual way in such switches.
  • the short-circuit sizes at the buttons can be set there.
  • the circuit breaker for mounting a short-circuiter 30 can be configured both on the network side NS of the circuit breaker and on the load side LS of the circuit breaker. It should be noted that in FIGS. 1 and 3, the load side LS is at the top and in FIG. 2 the load side LS is at the bottom.
  • a pyrotechnic generator with reference numeral 35 is indicated in the short-circuiter.
  • the connection plugs are protected against unintentional removal.
  • the connection rails 34 of the short-circuiter 30, in which holes 32 'are present, are contacted at the attachment points with the busbars 12 and / or 12' and thus connected in parallel. The short-circuiter 30 is triggered when a fault current occurs, especially in the event of a short circuit in the electrical system 40.
  • circuit diagram of the circuit breaker-short-circuiter combination is shown schematically in Fig. 2.
  • a short circuit is detected by the electronic detection unit 20 of the circuit breaker (short-circuit release), but not by the overload release.
  • the core of the detection unit 20 is a current transformer 21.
  • the detection unit is set to predetermined values (threshold) of current slope and current.
  • a predetermined threshold for example when an arc fault 77 occurs, the detection unit 20 sends a signal (S1, S2) both to the short-circuiter 30 and to the switch lock with a 'command' S2 for opening the contacts of the circuit breaker 10.
  • Electrical contact means are identified by reference numerals 24 ', 24 ", which are designed to receive electrical countercontact means 36', 36" arranged on the short-circuiting device.
  • the electrical contact means (such as plugs and sockets) are automatically coupled during assembly of the short circuiter.
  • the blocking function can be mechanical or electromechanical.
  • the short-circuiter should be replaced by a new functional short-circuiter.
  • the blocking function is also canceled.
  • the circuit breaker is equipped for the multiple switching of a short-circuit current, so that it can continue to be operated in case of multiple occurrence of a fault current.
  • a detection unit for an arc fault Reference has already been made to such a recording system (EP 0575 932 B1 ).
  • an optical unit with optical waveguides is used, which is coupled to a parallel current detection (for example via Hall sensors).
  • a switching signal S3 is given by the arc fault detection unit to the short-circuiter, which is thus caused to act.
  • FIG. 3 again shows a perspective view according to FIG. 2 with a schematically illustrated compartment 14 'on the load side LS (top) and a compartment 14 on the network side NS (bottom) for installation of the short circuiter 35.
