Definitions

the invention relates to multi-pole circuit breakers made of assembled machines or poles, at least for an outer conductor, the automat having its own trigger, and for a center conductor, the automat being unlatched by the automat (s) for outer conductors without the own trigger, which leads to the opening of his contact.
Machines with their own trigger are also called protected machines or poles and machines without their own trigger are unprotected machines or unprotected poles.
circuit breakers it is common practice to provide arc running aids.
blow loops can be formed in the power supply to the contact or arc entry aids into the quenching plates by means of a power supply line arranged in front of the front side of the quenching plates (DE-PS 26 09 708).
Arc running aids can also be designed as a special guide for the gas flow, as a so-called flow (DE: P 33 11 052).
the invention is based on the finding that in the machine or pole for the center conductor, hereinafter referred to as the Mp conductor, the contact pieces are exposed to increased erosion because the forces of the arcing aids open the contact of the Mp pole before the release mechanism is released or poles for the outer conductors.
the invention has for its object to avoid the increased erosion of the contact pieces of the MP machine in multi-pole circuit breakers.
the solution to the described problem is that precautions for promoting the arcing are formed only in or in the machines for outer conductors in the current supply for the contact. This delays the occurrence of the arc in the machine for the Mp conductor compared to the other poles, so that the release from a machine for outer conductors, i.e. from a protected pole, takes place in good time before the current in the machine for the Mp conductor could lead to the opening of the not yet released contact. The erosion of this contact is significantly reduced, so that power restrictions in the use of the multi-pole circuit breaker or complex additional measures such as significantly increased contact forces or particularly durable contact pieces are unnecessary.
the multi-pole circuit breaker made of assembled machines or poles has at least one for an outer conductor, for example according to FIG. 1. It is assembled with an automatic machine according to one of FIGS. 2 to 4, that is to say one for the Mp conductor.
the automat for the Mp conductor can be arranged in front of or behind the plane of the drawing with reference to FIG. 1.
the automat for an outer conductor has its own trigger, a thermal and / or magnetic trigger below or to the side of the switch lock 1.
the automat for the Mp conductor according to FIG. 2 does not have its own trigger; it is also unlatched by a vending machine for the outer conductor when this is released by a trigger.
the switch lock 1 of the machine for an outer conductor If the switch lock 1 of the machine for an outer conductor is released, its will Contact with the fixed contact piece 2 and the movable contact piece 3 opened and via a coupling 4, the switching lock 1 of the machine according to FIG. 2 also unlatched, so that its contact with the fixed contact piece 2 and the movable contact piece 3 is opened, as shown by the broken line is illustrated.
this is a blow loop, which is formed in that the feed line, viewed in the direction of arc 6, is connected behind the fixed contact piece 2 to the arc rail 7.
the feed line 8 seen in the direction of arcing 6 is connected to the arcing rail 7 on the fixed contact piece 2.
an arc inlet aid is formed in front of the quenching plates in the form of a feed line 9 running along the end faces of the quenching plates below the plane in which the movable contact piece 3 is guided.
the feed line 9 is designed according to FIG. 1 for reasons of series production.
the space for the magnetic release 10 and for the thermal release 11 is not populated.
the feed line 8 seen in the direction of arcing 6, is connected to the arcing rail 7 in front of the fixed contact piece 2. Even so, there is no blow loop in the lead to the contact. 4, the supply line 8 is connected directly in the vicinity of the connection terminal 12 to the arc guide rail 7, so that here too no starting aid for the arc to be drawn between the fixed contact piece 2 and the movable contact piece 3 when opened of contact. Since the arc is on the unprotected machine, neither a start-up aid that could open the contacts too early nor a start-up aid is required. The extinguishing plates can therefore also be omitted. The illustration according to FIGS. 2 to 4 is then to be understood in such a way that only the shapes for inserting extinguishing plates are shown in the quenching chamber.
