Abstract

The utility model provides a mining feed switch which is longer in service life and does not need to frequently replace isolating bolts. The mining feed switch comprises a housing, as well as an incoming line binding post and an outgoing line binding post which are arranged on the housing, wherein a vacuum circuit breaker, an incoming line isolating bolt and an outgoing line isolating bolt are arranged in the housing; the incoming line binding post is connected with one end of the incoming line isolating bolt through a cable conducting wire, the other end of the incoming line isolating bolt is connected with the line incoming end of the vacuum circuit breaker, the line outgoing end of the vacuum circuit breaker is connected with one end of the outgoing line isolating bolt, the other end of the outgoing line isolating bolt is connected with the outgoing line binding post through the cable conducting wire, and a conductive plate is connected at one end of the outgoing line isolating bolt and one end of the incoming line isolating bolt so as to be capable of being connected with the other end of the outgoing line isolating bolt and the other end of the incoming line isolating bolt in any position. When two end points of the outgoing line isolating bolt and the incoming line isolating bolt generate displacement, the two end points can also be connected for electric conduction through axial movement. The mining feed switch has the characteristic of long service life.

Description

Mining feeding switch

Technical field

The utility model relates to a kind of feeding switch, especially a kind of mining feeding switch.

Background technology

Present common mining feeding switch is mainly used in the power supply system under the coal mine, and its structure comprises the mechanical freeze mode low-voltage vacuum circuit breaker that is installed in the flameproof enclosure, the control panel and the blocking mechanism of elements such as installation protector; Wherein, mechanical freeze mode vacuum circuit-breaker is equipped with the three-phase vacuum tube, and its operation principle is; Three releases, i.e. device for under-voltage releasing equipment, shunt release and hand trip gear, this mechanical freeze mode feeding switch; Because environment for use is abominable, vacuum circuit-breaker quality problems etc. may cause the phenomenon of vacuum tube adhesion; Exist feeding switch to show outage, and actual still charged situation; If open door closure and overhaul this moment, cause mine safety accidents easily.

Therefore, a kind of mining feeding switch of physics outage occurred, set up in the vacuum circuit-breaker outside and isolated latch and latch occurs isolating; Manually move vacuum circuit-breaker and make that isolating latch physics cuts off the power supply; But isolate latch in long-term use, dislocation can occur, can not communicate with terminals; Therefore often need repairing, change and isolate latch.

The utility model content

The utility model provides a kind of mining feeding switch that does not need often to change the isolation latch of longer service life.

Realize the mining feeding switch of the utility model purpose; Comprise housing; Be arranged on inlet wire binding post and outlet binding post on the housing, in said housing, be provided with vacuum circuit-breaker, inlet wire isolates latch and latch is isolated in outlet; The said binding post that carries out connects said inlet wire isolation latch one end through cable conductor; Said inlet wire is isolated the end of incoming cables that the latch other end connects said vacuum circuit-breaker, and said vacuum circuit-breaker leading-out terminal connects said outlet and isolates latch one end, and the other end that latch is isolated in said outlet connects said outlet binding post through cable conductor; The end that latch and inlet wire isolation latch are isolated in said outlet is connected with conductive plate, can be connected in arbitrary position with the other end of said outlet isolation latch and inlet wire isolation latch.

Also be provided with handle on the said housing, the said vacuum circuit-breaker of the inboard interlock of handle is equipped with pulley in the said housing, and said vacuum circuit-breaker can slide on said pulley.

The beneficial effect of the utility model is following:

The mining feeding switch of the utility model; Isolate the end that latch and inlet wire isolate latch in outlet and be respectively equipped with conductive plate, can on arbitrary position, be connected with the other end that latch and inlet wire isolation latch are isolated in outlet, therefore; When two end points of outlet isolation latch and inlet wire isolation latch are subjected to displacement; Also can be through moving axially but two end points link to each other conduction, improved the useful life of isolating latch greatly, reduced the maintenance frequency of mining feeding switch.

Description of drawings

Fig. 1 is the structural representation of the mining feeding switch of the utility model.

Embodiment

The embodiment of the utility model is following:

As shown in Figure 1; The mining feeding switch of the utility model comprises housing 1, is arranged on inlet wire binding post 2 and outlet binding post 3 on the housing 1; In said housing 1, be provided with vacuum circuit-breaker 4; Inlet wire is isolated latch 7 and is isolated latch 8 with outlet, and said inlet wire binding post 2 connects the end that said inlet wire is isolated latch 7 through cable conductor 6, and said inlet wire is isolated the end of incoming cables that latch 7 other ends connect said vacuum circuit-breaker 4; Said vacuum circuit-breaker 4 leading-out terminals connect the end that latch 8 is isolated in said outlet; The other end that latch 8 is isolated in said outlet connects said outlet binding post 3 through cable conductor 6, and said outlet isolation latch 8 is connected with conductive plate 10 with the end that inlet wire is isolated latch 7, can isolate latch 8 with said outlet and be connected in arbitrary position with the other end that inlet wire is isolated latch 7.

Also be provided with handle 5 on the said housing, the said vacuum circuit-breaker 4 of the inboard interlock of handle, 1 is equipped with pulley 9 in the said housing, and said vacuum circuit-breaker 4 can slide on said pulley 9.

The mining feeding switch of the utility model; Isolate the end that latch 8 and inlet wire isolate latch 7 in outlet and be respectively equipped with conductive plate 10, can on arbitrary position, be connected with the other end that latch 8 and inlet wire isolation latch 7 are isolated in outlet, therefore; When two end points of outlet isolation latch 8 and inlet wire isolation latch 7 are subjected to displacement; Also can be through moving axially but two end points link to each other conduction, improved the useful life of isolating latch greatly, reduced the maintenance frequency of mining feeding switch.

Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineers and technicians in this area make the utility model technical scheme all should fall in the protection range that claims of the utility model confirm.
