Description

Technical Field

[0001] This utility model relates to the field of high-voltage motor technology, and in particular to an online insulation monitoring device for high-voltage motors. Background Technology

[0002] Online insulation monitoring equipment for high-voltage motors is a device used to monitor the insulation condition of high-voltage motors. This equipment typically uses sensors installed inside or outside the motor windings to monitor the state of the insulation material in real time, enabling timely detection and prevention of potential faults. The equipment can monitor the electrical characteristics of the insulation material, including insulation resistance, insulation capacitance, and dielectric loss. When abnormalities occur in the insulation material, such as insulation damage, excessive humidity, or excessive contamination, the equipment will issue an alarm to prompt maintenance personnel to take appropriate measures.
