摘要
Abstract
Both sides of the high and low voltages of the auxiliary transformer,which is in the standby state for long time in the nuclear power plant,is still balanced after the single phase open on the high voltage side,posing a threat to the safe operation of nuclear power units.In order to detect the open-phase timely,the optical current transformer is selected to measure the current of the high voltage side accurately according to other electrical characteristics of the auxiliary transformer after phase open,and the corresponding identifying logic is developed according to different working conditions to determine the open-phase monitoring scheme.The setting method,resolution and measuring range of the optical current transformer are studied to understand its technical characteristics.The open-phase monitoring system is introduced from the aspects of hardware,software and logic.At last,maintenance strategy of regular inspection for optical current transformer is given.关键词
