Product introduction:
QB500W insulation monitor for wind power generation is an insulation monitor specially tailored for the wind power generation industry. QB500W insulation monitor is an online insulation monitoring device for wind power generation units launched according to the application characteristics of wind power generators. It uses DC injection method to measure the insulation of cables or electrical winding, etc. The test voltage is DC500V, and the instrument is interlocked with the wind power generator circuit, It automatically realizes the separation of the insulation monitor from the power grid when the generator is running. When the generator is stopped, the insulation monitor automatically starts to detect the insulation between the generator stator winding to ground, the rotor winding to ground, and the stator winding to rotor winding. This product can effectively eliminate the cost and safety risk of manual measurement of megohmmeter
