The invention relates to the technical field of electric equipment, in particular to a starting and stopping method for a mine electric motor. The starting cabinet used in the method comprises a base,a power distribution cabinet, a mounting door, a fixing structure and a heat dissipation structure, wherein the side wall of the power distribution cabinet is provided with a mounting door for installing electrical components; the top of the power distribution cabinet is provided with a fixing structure for fixing the wires; and the side wall of the power distribution cabinet is provided with twosymmetrical heat dissipation structures for ventilation and heat dissipation. The fixing structure of the invention is convenient for connecting the wire and the power distribution cabinet as a whole, thereby improving the stability of the connection between the wire and the power distribution cabinet, being convenient for filling the sealing glue between the fixed structure and the wire, improving the sealing performance of the wire connection, and improving the waterproof and leakage prevention performance. The two symmetric side walls of the power distribution cabinet are provided with a heat dissipation structure, which enhances the air circulation inside the air and the power distribution cabinet with dustproof and waterproof performance, and at the same time, is convenient to disassemble the heat dissipation structure so as to inspect and maintain the heat dissipation structure.
Description
technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a method for starting and stopping a mining motor. Background technique [0002] With the high development of electrification, starter cabinets are widely used for starting various high-power motors. The soft start is used to replace the traditional starting method to achieve smooth start, reduce the starting current, and reduce the mechanical impact of large current on the motor when the motor is started. , and the impact on the power grid, improve the quality of electricity consumption, save energy, use the stall protection and fast protection to avoid mechanical failure or blockage caused by motor overheating and burnt, reduce the voltage drop caused by large current, affecting other electrical appliances, Reduce wear, prolong the service life of the motor, save the maintenance cost of the machine, and make the control of the motor more convenient and flexible...
