AI Technical Summary

Technical Problem

When maintaining explosion-proof permanent magnet motors used in flammable and explosive environments, frequent opening of the cover causes wear on the explosion-proof mating surfaces, posing a safety hazard. Furthermore, it is difficult to quickly disconnect the circuit without damaging the integrity of the motor housing, affecting maintenance efficiency and safety.

Method used

An explosion-proof permanent magnet motor with an explosion-proof connector module is used. The plug is directly connected to the first explosion-proof threaded mating surface of the explosion-proof gland, and the socket is fixed to the sealed cover using the second explosion-proof threaded mating surface, forming a double mechanical explosion-proof barrier. Combined with a stepped safety plug-in mechanism, the motor and cable can be quickly and safely separated.

Benefits of technology

It enables rapid and safe separation of motors and cables in flammable and explosive environments, improves maintenance efficiency and the inherent safety level of equipment, meets the strict safety standards of Zone 1 hazardous locations, and avoids the risk of arc ignition during plugging and unplugging.

Abstract

This application relates to an explosion-proof permanent magnet motor with an explosion-proof aviation connector, belonging to the technical field of explosion-proof motors. It includes a motor body and an explosion-proof aviation connector module. The cable lead-out end of the motor body is provided with a sealed cover. The explosion-proof aviation connector module includes: a plug assembly, which includes a plug body and a first electrical contact interface portion disposed on the plug body; an explosion-proof gland for sealing and fixing external cables; and a socket assembly, which includes a socket body and a second electrical contact interface portion disposed on the socket body. The second electrical contact interface portion is adapted to the first electrical contact interface portion and is electrically connected to the cable lead of the motor body. The plug body is threadedly connected to the explosion-proof gland through a first explosion-proof threaded mating surface; the socket body is threadedly connected to the sealed cover through a second explosion-proof threaded mating surface. This application allows for rapid separation of the motor body and cable by disassembling the explosion-proof aviation connector module, improving maintenance efficiency and explosion-proof safety in flammable and explosive environments.
