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 an intelligent vacuum contactor. The intelligent vacuum contactor comprises a frame, and a vacuum contactor, an electric steering mechanism and a comprehensive protector, which are arranged on the frame, wherein the vacuum contactor comprises three vacuum switch tubes and a permanent magnet type operation mechanism, the permanent magnet type operation mechanism drives moving contacts in the three vacuum switch tubes to perform switching motions, each static contact in each vacuum switch tube is stretched out of the wall of the frame, and a portion of each static contact, stretched out of the wall of the frame, is directly used as a plug-in type power side power connection pillar. The intelligent vacuum contactor directly integrates each static contacts in each vacuum switch tube with each power side power connection pillar, can reduce the self weight, is convenient to install, and simultaneously can greatly compress volume space, and conforms to development demands of miniaturization and intelligence of underground mining equipment.

Description

technical field [0001] The invention belongs to the technical field of vacuum contactor structure design, and in particular relates to an 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 watch...
