Problems solved by technology
[0003] At present, when the power distribution device of mine explosion-proof high-voltage vacuum power distribution device is used for power outage maintenance, it is necessary to manually hang the ground wire. Manually hang the ground wire to open the cover of the cable room. Once the cover of the cable room is opened, The cable room is exposed to the underground air. At this time, the artificial grounding wire is very likely to spark. Once the gas concentration in the underground air is suitable, it will cause an explosion.

The invention relates to a side-mounted mine explosion-proof high-voltage vacuum power distribution device, which includes an isolating switch, a static contact, a bus bar, a second insulator, a second bushing, a third bushing, a third conductor, a third Rotating shaft, vacuum interrupter, flexible connection, first insulator, permanent magnet mechanism, current transformer, lightning arrester, insulator pull rod, second rotating shaft, crank arm, insulating partition, circuit breaker chamber door, integrated microcomputer protection, discharge switch, The first casing, the first conductor, the connecting plate and the first rotating shaft. Since the present invention is provided with an isolating switch in the busbar room, it can conveniently cut off the connection with the high voltage to form an air-insulated fracture; a discharge switch is provided in the cable room to avoid the hidden danger of accidents caused by sparks caused by artificially hanging the ground wire; the present invention has small width and depth , It can be equipped with a discharge switch and has the advantages of simple electrical connection.
Description
technical field [0001] The invention belongs to the technical field of high-voltage electrical equipment, and in particular relates to a side-mounted mine explosion-proof high-voltage vacuum power distribution device for receiving and distributing electric energy. Background technique [0002] At present, the three-phase poles of the circuit breaker installed in the general mining explosion-proof high-voltage vacuum power distribution device are arranged according to A, B, C, left, middle and right, and the electrical connection between the circuit breaker and the adjacent power distribution device is a cable. Or soft connection and realized through the joint tube, such a connection method makes the large space of the flameproof device not be effectively used, especially the width direction and the large scale of the occupied area, which reduces the load of the coal mine underground substation Density increases the investment in the excavation of underground substation caver...
