Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic starters, in particular to a mine-used explosion-proof vacuum electromagnetic starter. Background Art

[0002] The mine flameproof vacuum electromagnetic starter is mainly used to control the direct start, stop and forward and reverse operation of the mine induction motor, and can protect the motor from overload and phase failure. It adopts a quick-opening door structure, which is simple and reasonable, easy to operate, and the body adopts a vertical plate type, using a simple control circuit, which is easy to maintain. The starter starts and stops the load at a long distance, and has protection functions such as overload, phase failure, short circuit, and leakage lock detection. The mine flameproof vacuum electromagnetic starter consists of a flameproof shell and an AC vacuum contactor, an isolating switch, a control button, a control transformer, a jdb integrated protector, a resistor-capacitor protection device and other components installed in the shell.

[0003] A flameproof intrinsically safe vacuum electromagnetic starter for mining is disclosed in the Chinese utility model patent application disclosure specification CN202122462616.9. When the current starter is in use, the current vacuum electromagnetic starter lacks a well-structured base bracket, which is prone to cause the body to tip over due to vibration, which is troublesome. It not only affects the safe use of the vacuum electromagnetic starter, but also consumes more manpower. When the flameproof vacuum electromagnetic starter for mining is in use, the ground is uneven, which makes the flameproof vacuum electromagnetic starter for mining easy to displace or tip over, which is inconvenient to use. Therefore, a flameproof vacuum electromagnetic starter for mining is needed. Utility Model Content
