Flameproof type auxiliary junction box used for four-level flameproof three-phase asynchronous motor

Abstract

The invention relates to a junction box, in particular to a flameproof type auxiliary junction box used for a four-level flameproof three-phase asynchronous motor, and belongs to the technical field of three-phase asynchronous motor flameproof wiring. According to the technical scheme, the flameproof type auxiliary junction box comprises a junction box base, a plurality of incoming line ports and a plurality of outgoing line ports, wherein the incoming line ports and the outgoing line ports are located in the junction box base. The inside of the junction box base is provided with a baffle, a weak current wiring area and a strong current wiring area are formed in the junction box base through the baffle, a bearing temperature measurement wiring panel and a stator temperature measurement wiring panel are arranged in the weak current wiring area, a heater wiring panel is arranged in the strong current wiring area, and the junction box base is provided with junction box covers which are used for sealing the weak current wiring area and the strong current wiring area respectively. The flameproof type auxiliary junction box is simple, compact and reasonable in structure, convenient in wiring, capable of meeting four-level flameproof requirements, wide in application range, safe and reliable.

Description

technical field [0001] The invention relates to a junction box, in particular to a flameproof auxiliary junction box for a four-stage flameproof three-phase asynchronous motor, belonging to the technical field of flameproof wiring of a three-phase asynchronous motor. Background technique [0002] For many years, it has been difficult to manufacture the junction box for bearing temperature measurement, stator temperature measurement and stator heating of four-stage flameproof three-phase asynchronous motors, and users rarely use temperature measurement devices. With the development of industry and the improvement of the overall level of the manufacturing industry, in recent years, many users have higher and higher requirements for adding temperature measurement and heating devices to four-stage flameproof motors. Therefore, it is becoming more and more difficult for existing junction boxes to meet industrial use. requirements. Contents of the invention [0003] The purpose...
