Study on Electroscope of UHV Equipment based on ZnS Material

摘要

UHV equipment charged instructions plays a very important role for the maintenance of workers' personal safety. Low-voltage side usually use the electroscope, but there is no appropriate electroscope for the high-voltage side. As the voltage increases, the greater the safety distance is required, the length and deflection of inspection pole cannot meet the requirements. In this paper, ZnS electro chromic devices were fabricated, and the devices were encapsulated by screen printing. We obtained the volt-ampere characteristics through the power-on test, and the light-emitting situation, and the devices were tested under the actual high-voltage electric field. Experiments show that the device has the effect of inspection, which can be installed directly on the surface of charging equipment. So it can be used for charging indicator.
