Description
Technical field
The utility model relates to circuit switchgear, relates in particular to the light distribution box and the unipolar low-voltage circuit breaker thereof that are used for factory building.
Background technology
The factory floor illuminating lamp adopts the light distribution box centralized control usually, and master switch and several switch-dividings are housed in the light distribution box, and all switch-dividings are parallel to the master switch output, and each switch-dividing is controlled the illuminating lamp that is distributed in the workshop different station respectively.What be used as switch-dividing is a kind of unipolar low-voltage circuit breaker, and at present, existing this unipolar low-voltage circuit breaker only is provided with overload/and disengaging deivce of earth leakage, and the under voltage trip gear is not set.In factory, the workshop light distribution box is not equipped with the personal management usually, and the workman of each station does not know whether other station needs illumination yet, thereby, generally all only operate master switch, close during working, disconnect when coming off duty, all switch-dividings then remain on-state.Just there is following situation in this: have only minority station when work (for example overtime work at night) when the workshop, the light distribution box switching manipulation is very loaded down with trivial details, needs earlier not that the switch of work station disconnects one by one, and then the switch-dividing of close master switch and work station.If the workman lacks a sense of responsibility, dislike trouble, with usual the same, do not disconnect the not switch of work station, the master switch that just closes causes whole workshop brilliantly illuminated, the waste electric energy.At present, have to avoid taking place above-mentioned situation by strict management system constraint workman's behavior, obviously, the way of this dependence people's subjective consciousness is insecure, in fact, can deal with problems by technological means fully, fundamentally stop to occur the possibility of above-mentioned situation.
The utility model content
The purpose of this utility model is the shortcoming that overcomes existing light distribution box, and a kind of easy and simple to handle, light distribution box of saves energy and supporting unipolar low-voltage circuit breaker thereof are provided.
Technical solution of the present utility model is:
A kind of unipolar low-voltage circuit breaker comprises shell, arranges in the enclosure quiet, moving contact, and operating grip that cooperates with moving contact and release is characterized in that: also be provided with the under voltage trip gear, this device acts on release.
Described under voltage trip gear comprises shell, electromagnet, dropout transmission mechanism, and described electromagnet is made up of coil, moving iron core, static iron core, and coil is on static iron core; Described dropout transmission mechanism is made up of pull bar, spring, lever, the upper end of pull bar connects moving iron core, the lower end connects the spring upper end, the spring lower end is fixed on the shell, lever has the bolster hinged with it, and bolster is fixed on the shell, an end cylinder lever connecting rod of lever, the other end has driving lever, and cooperates with the release of circuit breaker by driving lever.
Above-mentioned unipolar low-voltage circuit breaker also is provided with the overlond trip device.
A kind of light distribution box, be furnished with master switch and some switch-dividings in the case, master switch is communicated with power supply, and all switch-dividings are parallel to the master switch output, it is characterized in that: described switch-dividing is adopted above-mentioned unipolar low-voltage circuit breaker, and its solenoid connects the electric power incoming line of circuit breaker.
The beneficial effects of the utility model: owing to have the under voltage trip gear as the unipolar low-voltage circuit breaker of switch-dividing, when the workshop station need throw light on, close behind the master switch, the switch-dividing of place station also must close, and the switch-dividing of other station still is in off-state, after master switch disconnected, all switch-dividings were because of the dead electricity automatic disconnection and by locking.Simple and quick, eliminated the illuminated possibility of inoperative station effectively, be not subjected to artificial factor, for saves energy provides technical guarantee.

Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
Referring to Fig. 1: unipolar low-voltage circuit breaker of the present utility model is combined by circuit breaker I and under voltage trip gear II two parts, and circuit breaker I can adopt existing DZ47, C45N serial plastic shell unipolar low-voltage circuit breaker, is furnished with the overlond trip device usually.
Referring to Fig. 2, Fig. 3: under voltage trip gear II is made of shell 1, electromagnet, dropout transmission mechanism three parts.Wherein: the outer contoured shape of shell 1 is similar to case for circuit breaker, main fit dimension unanimity, and it is attractive in appearance that global shape is coordinated, and be convenient to assembling; Electromagnet is the structure that people know, and is made of static iron core 2, the solenoid 4 on the static iron core 2, the moving iron core 3 that is arranged in static iron core; The dropout transmission mechanism is made up of pull bar 8, spring 9, lever 5, the upper end of pull bar 8 connects moving iron core 3, the lower end of pull bar 8 connects spring 9 upper ends, spring 9 lower ends are fixed on the shell 1, lever 5 has the bolster hinged with it 6, and bolster 6 is fixed on the shell 1, an end cylinder lever connecting rod 8 of lever 5, the other end has driving lever 7, and cooperates with the release 10 of circuit breaker by driving lever 7.Its operation principle is: under the normal operating conditions, solenoid 4 energisings, moving iron core 3 overcomes the elastic force of spring 9 under the electromagnetic force effect, be inhaled into static iron core 2, be in a high position, and through pull bar 8 spring 9 is stretched, lever 5 ends that are connected with pull bar 8 also are in a high position, correspondingly, driving lever 7 ends of lever 5 then are in low level, and driving lever 7 does not contact with the release 10 of circuit breaker I.When solenoid 4 dead electricity (under voltage), electromagnetic force disappears, spring 9 shrinks, the moving iron core 3 of drive, pull bar 8 move down and reset, pull bar 8 transmission levers 5, and it is the swing of fulcrum that lever 5 is taken place with bolster 6, an end that is connected with pull bar 8 moves down with pull bar, its driving lever 7 ends move on then, and driving lever 7 is upwards stirred release 10, make circuit breaker I tripping operation.
Referring to Fig. 4: light distribution box 11 of the present utility model, be furnished with master switch 13 and some switch-dividings 12 in the case, master switch 13 is communicated with power supplys, and all switch-dividings 12 are parallel to master switch 13 outputs, and switch-dividing 12 is all adopted above-mentioned unipolar low-voltage circuit breaker.Usually, light distribution box 11 uses three phase mains, and switch-dividing 12 is divided into three groups, connects three-phase respectively, makes the three-phase load distributed uniform.
Referring to Fig. 5, it should be noted that: light distribution box 11 back panel wirings, solenoid 4 should be connected on the electric power incoming line of circuit breaker I, can not be connected in the outlet, otherwise circuit breaker I can not close a floodgate.
The operating process of light distribution box:
When master switch 13 disconnects, all switch-dividings 12 also disconnect, and be in blocking (when master switch 13 does not close, switch-dividing 12 closes not brake application), when need throw light in the workshop, the master switch 13 that closes earlier, close again need the switch-dividing 12 of illumination station (this moment solenoid 4 electric, locking is eliminated).When not needing to throw light on, need only disconnect master switch 13, then all switch-dividing 12 automatic trips, and by locking.
