Description

Technical Field

[0001] The invention relates to the technical field of electromagnetic starters, in particular to an electromagnetic starter for mining. Background Art

[0002] Electromagnetic starter, also known as "magnetic starter", is a device that starts a high-power motor by converting electrical energy into mechanical energy. Electromagnetic starter is mainly composed of electromagnetic AC contactor, thermal relay and button. Mine electromagnetic starter is suitable for mines containing explosive gas and coal dust. It is mainly used to directly start or stop mining motors, and can also stop and change direction.

[0003] The mining electromagnetic starter includes a wiring cavity for connecting external equipment and power supply. The main cavity in the box body is equipped with a control element for controlling the power switch. By setting a translational quick-opening door structure and a control structure on one side of the box body, it can be ensured that the door can only be opened when the power is off. When the door needs to be opened, the handle of the door is turned, and the door will first move horizontally. If the cylinder of the control mechanism is located on one side of the door, the door cannot be opened. It is necessary to press the closing button first, and then turn the handle of the control mechanism so that the notch of the handle is located on one side of the cylinder, and then screw the cylinder into the notch. At this time, the handle of the door is turned horizontally for a distance, and then the door is pulled. At this time, the control element in the main cavity can be inspected and repaired.

[0004] Most of the control elements in the existing mining electromagnetic starters are fixed in the main cavity by bolts. Due to the harsh environment in the mining area, the equipment is prone to various problems, so the mining electromagnetic starters need to be inspected and repaired frequently.
