1000kV Dead Tank Type Capacitive Voltage Transformer

This product adopts a single coaxial gas insulation structure instead of a small unit series connection structure of oil-paper composite insulation, and is applied to 1000kV ultra-high voltage composite electrical appliances. It overcomes multiple key technologies such as equipment structure design, key technical parameter determination, ultra-fast transient overvoltage suppression, processing technology, equivalent testing methods, and operation error monitoring, breaking through the technological monopoly of foreign countries on China's ultra-high voltage, The product has been successfully applied in the Anhui East Power Transmission Huainan to Shanghai UHV AC Transmission Demonstration Project.
