The Wind Generator Insulation Resistance Monitoring System

      Because of wind turbine engine room closed and compact size, generator temperature rise significantly, and its operation winding environment is very bad. In addition, doubly-fed induction of wind turbine rotor connecting the converter trigger harmonic current, lead to copper consumption, consumption of iron, and the stator winding up will be under a lot of impulse voltage, its insulation problems than general motors is more outstanding. For offshore areas, and the wind generator wet salt fog pollution is added to the test of insulation system coil. WGAT is a set of online automatic monitoring device of the insulation resistance, it is suitable for various types of wind generators, but convenient installation in generator control enclosure. WGAT can halt in generator state of the automatic detection and coil winding the whole insulation level, and in insulating bad triggered when the closure or remote alarm signal, avoid operation personnel will be put into operation the generator insulation fault, lead to start-up failure. Maintenance staff can do early overhaul of the plan, prevent accident's occurrence and avoid unnecessary downtime and spending expensive generator maintenance costs.
