Description

Technical Field

[0001] The utility model relates to the technical field of insulation monitoring, in particular to a stator insulation monitoring device for a motor. Background Art

[0002] Electric motors are the most widely used power equipment in various enterprises. The safe and stable operation of electric motors is directly related to the normal operation of production equipment. According to statistics from relevant enterprises, motor damage caused by reduced insulation of motor windings accounts for more than 80% of the causes of motor failures. Therefore, the detection of motor winding insulation during operation has always been valued by people.

[0003] The reference authorization number is "CN 218099438 U", and the name is "A real-time online detection device for motor insulation". Although this application solves the problem that "in order to improve the detection efficiency, most of the time, the insulation of the motor winding is detected by an insulation detector. The detection input end of the insulation detector is connected to the star point of three high-voltage resistors, and the other ends of the three high-voltage resistors are respectively connected to the three stator windings of the motor to realize the insulation detection of the motor winding. However, the dust resistance of the detection equipment is poor, and the operator needs to regularly disassemble the shell of the detection equipment to clean it, and the cleaning efficiency is slow." However, it also has some defects. For example, in the above application, the filter cannot be disassembled and cleaned. Long-term use may easily lead to excessive dust on the surface of the filter, affecting the dust collection effect. Moreover, in the above application, the touch screen is mostly directly exposed to the external environment. When not in use, external hard objects may easily knock against the touch screen, causing damage to it, affecting its use. Therefore, a stator insulation monitoring device for a motor is proposed to solve the above-mentioned technical problems. Utility Model Content
