Causes and Measures of Winding Short Circuit
The winding short circuit will cause serious damage to the motor and other electrical equipment. In order to prevent the occurrence of winding short circuit accidents and ensure the safe operation of electric motor, it is necessary to understand the causes and corresponding preventive measures in depth.
First of all, the main causes of winding short circuit accidents are mainly divided into two categories. One is due to the internal insulation failure of the winding, such as insulation aging and cracking; the other is due to the short circuit between the turns of the winding. The former may be caused by the quality problems of the materials used in the winding or the manufacturing and installation process, while the latter may be caused by incorrect coil winding and serious voltage fluctuations.
In order to avoid the occurrence of the winding short circuit and ensure the safe operation of the motor, it is necessary to take corresponding measures according to the above two situations. The former mainly focuses on selecting the high-quality materials for the winding and improving the insulation manufacturing, installation and maintenance process. The latter should focus on the selection of appropriate coil winding process, reasonable installation of coil and reasonable adjustment of voltage.
In addition, regular inspections should be carried out, and suspected short-circuited windings should be detected and replaced in time. Appropriate insulation measures should be combined with anti-thunder measures to avoid the instantaneous overvoltage destruction induced by the impact of lightning strike and line fault. In conclusion, the winding short circuit is a common problem in electricity. To reduce the occurrence, we should start from the causes and take corresponding measures to ensure the safe operation of the motor.
