Development of a maintenance device for busbar PT voltage air switch
摘要
Abstract
When the voltage air switch of busbar potential transformer (PT) breaks down, it takes long time of switching operation before maintenance, which seriously delays the restoration time. Based on the principle of multiple circuit, a live replacement maintenance device for PT voltage air switch is proposed. The following aspects are involved in the de-sign of the device:the principle of device, component selection, device assembly and operation process. Through func-tional test in simulation substation and on-site installation, it is proved that the failed air switch can be lively replaced by the device without switching operation, which greatly reduces the risk on power grid caused by such failed air switch.关键词
