Problems solved by technology

[0002] At present, the vacuum contactor assembly used in the high, medium and low voltage switches of the coal mine explosion-proof power supply system has a structure: a vacuum contactor and a reversing switch are installed with a protector, and the connection is fixed with screws through a copper braid. The process is complicated, and because of too many connecting wires, it increases the safety risk of the product during operation
In addition, explosion-proof switches made of traditional vacuum contactors have technical and technical problems such as large volume, high temperature, manual reversing, and disordered internal wiring of the switch. More importantly, the existing explosion-proof switches have no obvious isolation fractures. , can not guarantee the technical problems that may endanger the safety of life caused by the operator and the electrician during maintenance.

Abstract

The invention discloses a mining vacuum feeder switch device with isolating fractures. The mining vacuum feeder switch device comprises an anti-explosion shell, an intelligent vacuum contactor arranged in the anti-explosion shell and a conductive mechanism electrically connected with the vacuum contactor, and is characterized in that a displacement mechanism used for driving the intelligent vacuum contactor to reciprocate is further arranged in the anti-explosion shell; the intelligent vacuum contactor is provided with inserted connection type power-side electric columns, and the conductive mechanism is provided with inserted connection type power-side electric sleeves; under the driving of the displacement mechanism, the intelligent vacuum contactor drives the power-side electric columns on the intelligent vacuum contactor to be inserted into or moved out of the corresponding power-side electric sleeves in the conductive mechanism, and the isolating fractures are formed by the power-side electric columns and the corresponding power-side electric sleeves after the power-side electric columns are moved out; a transparent observing window used for observing the isolating fractures is arranged in the anti-explosion shell. According to the mining vacuum feeder switch device, as the visible isolating fractures are formed, the safety performance is greatly improved.
