Problems solved by technology

Most of the high-voltage load switches and low-voltage feed switches used in mining explosion-proof high-voltage and low-voltage power distribution devices are vacuum structures, that is, high-voltage vacuum load switches and low-voltage vacuum feed switches, which have large no-load losses and are easy to trip , The life of the switch is short; there are also advanced permanent magnet vacuum structures, that is, high-voltage permanent magnet vacuum switches and low-voltage permanent magnet vacuum feed switches, but the doors of the high and low voltage distribution boxes are bolted, and it is time-consuming to open the doors, and maintenance is very inconvenient , the structure still needs to be improved; and the intelligent control of module integration has not been realized

Embodiment Construction

[0011] Such as figure 1 As shown, the present invention includes a high-voltage switch 1, a low-voltage protection box 4, and high-voltage and low-voltage integrated intelligent control modules 2, 5; The two ends of the explosion transformer 3, the high-voltage switch 1 and the low-voltage protection box 4 are electrically connected with the mine explosion-proof transformer 3 through cables respectively, and the mine explosion-proof transformer 3 and the high-voltage and low-voltage integrated intelligent control modules 2 and 5 form an intelligent mine. Flameproof mobile substation.

[0012] The high-voltage switch 1 and the low-voltage protection box 4 belong to permanent magnet and vacuum switches, and fast-opening door structures are respectively fixed in them, and the equipment chamber door can be quickly opened by lifting two handles for quick processing. While the traditional screw door structure needs to unscrew more than 10 screws with a wrench to open the cavity doo...

Abstract

The invention discloses an intelligent mining explosive-proof type high-low voltage power distribution device. The high-low voltage power distribution device consists of a high-voltage switch, a low-voltage protection box and an intelligent module device and comprises a high-voltage load switch, the low-voltage protection box and an integrated intelligent control module, wherein the high-voltage switch and the low-voltage protection box utilize permanent magnetic, vacuum and quick opening structures and are also integrally controlled by a programmable controller and a Chinese character display module. The intelligent mining explosive-proof type high-low voltage power distribution device has an intelligent operation mode capable of breaking a high-voltage side power supply due to low-voltage side faults, performing on-site and remote transmission display under manual, automatic and remote control, can be applied to power transformation and distribution of mine underground or other inflammable and explosive areas on the ground, and has the advantages of being energy-saving, maintenance-free, stable in operation, good in safety, high in reliability, convenient in maintenance and long in service life.

Description

Technical field: [0001] The invention relates to a mine flameproof power distribution device, in particular to an intelligent mine flameproof high and low voltage power distribution device. Background technique: [0002] Mine explosion-proof high and low voltage power distribution device is the power distribution equipment matched with mine explosion-proof mobile substation, and is an indispensable explosion-proof power distribution device in coal mines. It usually consists of high-voltage load switch (or high-voltage switch), low-voltage feeder Electric switch (or low voltage protection box). Most of the high-voltage load switches and low-voltage feed switches used in mining explosion-proof high-voltage and low-voltage power distribution devices are vacuum structures, that is, high-voltage vacuum load switches and low-voltage vacuum feed switches, which have large no-load losses and are easy to trip , The life of the switch is short; there are also advanced permanent magne...
