Definitions

  • the invention relates to a short-circuit detector for signaling overcurrent and short-circuit tripping, in conjunction with a circuit breaker or motor protection switch, and the function of a short-circuit lock by manual reset on site.
  • short-circuit detectors particularly if they are connected to a circuit breaker or motor protection switch, switch in the event of a short-circuit as well as an overcurrent, it is important to be able to recognize the type of tripping from the outside, the short-circuit detector only detecting overcurrents above the approx. times the nominal current.
  • a separate auxiliary switch can be assigned to each locking lever in such a circuit breaker.
  • the invention has for its object to improve a short-circuit detector according to the preamble of claim 1 in such a way that a high level of functions is achieved by a simple structure and the short-circuit display and the resetting can be done manually by a single indicator plunger.
  • the reset button of the short-circuit detector is connected to a switch-on slide, which is operatively connected via a deflection lever to a trigger-blocking slide which can be displaced in parallel, which can be displaced in the triggering direction of a triggering device of the circuit breaker or motor-protective circuit-breaker and via a trigger pin with this triggering device in the triggering direction is connected, there is a particularly compact design of such a short-circuit detector, since the switch-on slide and the combined trigger-lock slide can be arranged directly next to one another in the switch housing.
  • a particularly reliable functioning of such a short-circuit detector is also achieved by the deflecting lever, and it is also possible to arrange a test opening in the axial extension of the trigger slide on the front narrow side of the switch housing directly next to the reset button, through which the trigger slide by means of a pointed object, such as a Screwdriver or the like, even without short-circuit release and without the circuit breaker or motor protection switch to which the short-circuit detector is connected being supplied with current can be triggered purely mechanically by hand for test purposes.
  • a pointed object such as a Screwdriver or the like
  • the short-circuit detector 1 can, as shown in Fig. 1, be laterally attached to a circuit breaker or motor protection switch 2 in such a way that it is in operative connection with a trigger pin 3 projecting from the side with a triggering device 4 on the circuit breaker or motor protection switch 2, which is at a short-circuit or overcurrent release of the circuit breaker or motor protection switch 2 is moved in the triggering direction of the short-circuit detector 1.
  • the short-circuit detector 1 has a manually operated reset button 5, which is arranged recessed in a recess 8 on the front narrow side 6 of the switch housing 7 such that it does not protrude beyond the level of the narrow side 6 of the housing and this level even in the OFF position thus is not interrupted by the reset button 5 even in the OFF position shown in FIGS. 1 and 4.
  • the short-circuit detector 1 has a switch-on slide 9 which can be operated manually via the reset button 5 and which is in operative connection via a bell crank 10 with a combined trigger-lock slide 11 which can be displaced in parallel therewith stands, which is displaceable in the direction of displacement 12 (FIG. 4) of the tripping device 4 of the circuit breaker or motor protection switch 2 and is positively connected to this tripping device 4 in the tripping direction 12 via a tripping pin 3.
  • the bell crank 10 is designed as a rocker in such a way that the switch-on slide 9 and the combined trigger-lock slide 11 can be moved in opposite directions parallel to one another. It is pivotally mounted between the switch-on slide 9 and the trigger-lock slide 11 parallel to it about a pivot 10a fixed to the housing and is pivotably connected to the switch-on slide 9 as well as to the trigger-lock slide 11 via slot-and-pin connections with play.
  • the deflection lever 10 has two oblong holes 10b, 10c, which run parallel to one another in relation to its longitudinal axis, for the engagement of two driving pins 9a, 11a, which protrude to the side from the switch-on slide 9 and from the release lock slide 11.
  • the combined trigger-blocking slide 11 is formed in two parts and consists of a on the switch housing 7 in lateral parallel guides 13 parallel to the switch-on slide 9 displaceable trigger slide 14 and a locking slide 16 telescopically displaceable therebetween between lateral guide cheeks 15, which is in the ON position of the trigger slide 14 in a first locking position from which it can be moved into a position after releasing a lock by moving the trigger slide 14, in which the switch-on slide 9 has been moved via the switch lever 10 from its ON position shown in FIGS. 2 and 3 to its OFF position in FIG. 4.
  • the trigger slide 14 on the housing 7 of the short-circuit detector 1 is guided in the triggering direction 12 of the triggering device 4 on the associated circuit breaker 1 and engages with its trigger pin 3, which passes through the housing walls 7a, 2a of the switches 1, 2 mounted directly next to one another in elongated holes 3a, 3b into a recess 4a on the tripping device 4 of the circuit breaker or motor protection switch 2.
  • the locking slide 16 of the short-circuit detector 1 is displaceably arranged in the triggering direction 12 of the trigger slide 14 in its axial extension or coaxially with the trigger slide 14 in the switch housing 7 and engages with a pawl 17 which rests transversely to the triggering direction 12 and counteracts a web-shaped abutment 18 on the switch housing 7 the release direction 12 locking hook-shaped.
  • the web-shaped abutment 18 is formed in the embodiment shown from the edge of the recess or opening 19 for the trigger pin 3, which protrudes laterally from the trigger slide 14 of the short-circuit detector 1 and is in operative connection with the trigger device 4 on the power or motor protection switch 2.
  • the trigger slide 14 and the pawl 17 on the locking slide 16 have transverse to the triggering direction 12 of the short-circuit detector 1 parallel inclined surfaces 20, 21 which are inclined so that the pawl 17 is pushed aside when the trigger slide 14 is moved and with it Locking lug is released from the abutment web 18 or from the lower edge of the recess 19 on the switch housing 7, so that the locking slide 16 together with the trigger slide 14 can reach the OFF position of the short-circuit detector 1 from FIG. 4.
  • the locking slide 16 is also under the action of a tension spring 22, which moves it after releasing the lock due to the displacement of the trigger slide 14 together with the bell crank 10 in the switch-off position and holds it in this position until it is actuated by the reset button 5 via the switch-on slide 9 and the bell crank 10 has been moved back into its locking position of FIGS. 2 and 3.
  • a test opening 24 is arranged in the axial extension of the trigger slide 14 on the front narrow side 6 of the switch housing 7, through which the trigger slide 14 is by means of a sharp object, such as a screwdriver or the like, even without a short-circuit release and without the circuit breaker or motor protection switch 2, with which the short-circuit detector 1 is connected, supplied with current, can be triggered purely mechanically by hand for test purposes.
  • the switch-on slide 9 is connected to at least two counter-acting auxiliary switches, a break contact 25 and a make contact 26.
