Abstract
An electronic voltage transformer for a high-voltage cubicle type gas insulated switchgear comprises a transformer body, a cable contact head, a primary high voltage winding and an amorphous core. The amorphous core is arranged at the center of the transformer main body; a secondary winding is wound on the right side of an insulating layer of the amorphous core; an insulting layer and the primary high voltage winding are arranged on the outer layer of the secondary winding; epoxy resin mixed glue is poured in the residual space of the transformer main body; and the cable contact head and an aerial socket are arranged on one side of an aluminum alloy case of the transformer main body. The electronic voltage transformer is made into an insulated fully-enclosed support post structure through pouring of epoxy resin, is fouling-resistant and moist-resistant and can be installed at any position and in any direction. Meanwhile, the voltage transformer has the advantages that the measurement range is wide, no high voltage is generated in the secondary open circuit, the secondary output is small voltage signals with ultra-low power and conversion from large signals to small signals is not needed, and the performance is quite stable.
