Abstract

The utility model discloses a low-voltage power distribution cabinet with protection, comprising a low-voltage power distribution cabinet. The low-voltage power distribution cabinet is internally provided with a low-voltage breaker and a mandril-type AC contactor, wherein the low-voltage breaker is connected with the mandril-type AC contactor, and the mandril-type AC contactor is provided with a mandril, a node and a coil. The low-voltage power distribution cabinet is internally provided with the mandril-type AC contactor, thus, when a door of the low-voltage power distribution cabinet is closed, the door compresses the mandril of the mandril-type AC contactor, the compressed mandril drives the node to close, and a magnetic force generated by the coil after being electrified drives the low-voltage breaker in the low-voltage power distribution cabinet to switch on so as to safely supply power for loads. When the door is not closed in place or is opened, since the mandril of the mandril-type AC contactor returns back automatically, the mandril drives the node of the mandril-type AC contactor to break, in this way, electricity of the coil is cut off, the magnetic force generated by the coil disappears, and the low-voltage breaker in the low-voltage power distribution cabinet is switched off by itself, so as to realize safe power supply for the electricity loads.

Description

The low-tension distribution box of band protection
Technical field
The utility model belongs to the low-tension distribution box technical field, is specifically related to a kind of low-tension distribution box with protection.
Background technology
Present employed low-tension distribution box in electric power system is because the influence of factors such as service life and environment for use; Cause chamber door to close; Because low-tension distribution box lacks chamber door or chamber door can't be closed; When wiring into and out of the low-voltage cable of low-tension distribution box be not through the cable perforation of low-voltage distribution lower box part receive respectively low-voltage circuit breaker in the case into and out of the line two ends, but directly from chamber door receive low-voltage circuit breaker in the case into and out of the line two ends.Owing to lack chamber door, the binding post in the low-tension distribution box directly exposes, and scraped by wind to drench with rain, be easy to cause short circuit, and also there is certain threat in operating personnel's life security on every side.
The utility model content
The purpose of the utility model is to avoid above-mentioned weak point of the prior art, and the low-tension distribution box that a kind of security performance is high, can effectively protect low-tension distribution box, band easy to use to protect is provided.
The technical scheme that purpose adopted that realizes the utility model is: a kind of low-tension distribution box with protection; Comprise low-tension distribution box; Low-voltage circuit breaker and post rod type A.C. contactor are set in the said low-tension distribution box, and said low-voltage circuit breaker is connected with the post rod type A.C. contactor.
Said post rod type A.C. contactor is provided with push rod, node and coil.
Because the utility model is reasonably transformed low-tension distribution box; A post rod type A.C. contactor is installed in low-tension distribution box; Like this when the chamber door of low-tension distribution box is reliably closed; The push rod of low-voltage distribution chamber door compression post rod type A.C. contactor, compressed push rod drives the node adhesive of post rod type A.C. contactor, and the electromagnetic force that the charged back of coil of post rod type A.C. contactor is produced drives low-voltage circuit breaker in the low-tension distribution box and closes a floodgate safe power supply is carried out in load.When chamber door is closed not in place or after no matter which kind of reason is opened; Because the push rod of post rod type A.C. contactor returns automatically; The node that drives the post rod type A.C. contactor breaks off; Make the coil blackout of post rod type A.C. contactor, the electromagnetic force that coil produced disappears, and the low-voltage circuit breaker in the low-tension distribution box is separating brake outage voluntarily just.Thereby realized to safe power supply, also accomplished simultaneously that the utility model security performance is high, can effectively protect low-tension distribution box, easy to use to one protection of low-tension distribution box one machine one lock with electric loading.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1: a kind of low-tension distribution box with protection, comprise low-tension distribution box 1, low-voltage circuit breaker 2 and post rod type A.C. contactor 3 are set in the said low-tension distribution box 1, said low-voltage circuit breaker 2 is connected with post rod type A.C. contactor 3.
Said post rod type A.C. contactor 3 is provided with push rod 4, node 5 and coil 6.
Utilize the utility model; Low-tension distribution box is reasonably transformed; A post rod type A.C. contactor 3 is installed in low-tension distribution box 1; Like this when the chamber door of low-tension distribution box 1 is reliably closed; The push rod 4 of 1 of low-tension distribution box compression post rod type A.C. contactor 3, compressed push rod 4 drives node 5 adhesives of post rod type A.C. contactors 3, and the electromagnetic force that the coil 6 charged backs of post rod type A.C. contactor 3 are produced drives low-voltage circuit breaker 2 in the low-tension distribution box 1 and closes a floodgate safe power supply is carried out in load.When chamber door is closed not in place or after no matter which kind of reason is opened; Because the push rod 4 of post rod type A.C. contactor 3 returns automatically; The node 5 that drives post rod type A.C. contactor 3 breaks off; Make coil 6 outages of post rod type A.C. contactor 3, the electromagnetic force that coil 6 is produced disappears, and the low-voltage circuit breaker 2 in the low-tension distribution box 1 is separating brake outage voluntarily just.Thereby realized to safe power supply, also accomplished simultaneously that the utility model security performance is high, can effectively protect low-tension distribution box, easy to use to one protection of low-tension distribution box one machine one lock with electric loading.

Claims (2)
