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. , it is impossible for the user to directly observe its use status, which is prone to accidents

Abstract

The invention discloses a novel intelligent vacuum contactor. The novel intelligent vacuum contactor comprises a frame and a vacuum contactor and an integrated protection device arranged on the frame; the frame is provided with an electric reversing mechanism. The novel intelligent vacuum contactor is provided with the electric reversing mechanism for compensating the shortcomings of manual operation reversing operation of the existing product. Moreover, the position design of the electric reversing mechanism is reasonable for taking full advantage of the integrated space, and the structure is simple and compact for reducing the integrated usage space.

Description

technical field [0001] The invention belongs to the technical field of vacuum contactor structure design, and in particular relates to a novel intelligent vacuum contactor. Background technique [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 are fixed and connected by screws through a copper braid. The process is complicated, and because there are too many connecting wires, the safety risk during product operation is increased. 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. , It is impossible for the user to directly ...
