Description

technical field [0001] The invention belongs to the technical field of power insulation monitoring, and in particular relates to a leakage current monitoring device of a power insulating part. Background technique [0002] Solid insulators are widely used in the power industry and high-voltage electrical equipment. They are generally made of insulating materials with high dielectric constants such as ceramics, silicone rubber, glass, and polytetrafluoroethylene. They are used to connect live terminals and ground terminals of electrical equipment. , or the live ends of two different power sources, play the role of supporting the wires, letting the wires dance, isolating the live ends and grounding ends or isolating the live ends of different power sources. [0003] Insulators generally rely on their external extension surface and their own insulation properties to improve their insulation capacity. When rain, snow and pollution cause the outer insulating surface to form a con...
