Development and Application of Anti-Static Induction Device for 220kV Outdoor Current Transformer

Most 220kV outdoor current transformers in substations are oil-filled current transformers. Sampling and testing of the insulating oil play an important role in early detection of potential faults within the current transformer and timely warning of abnormal conditions. When the current transformer is powered to take oil samples, it is often affected by inductive electricity. In severe cases, the operator may fall from a high place. However, the personal security line is suitable for the connection between the power-off line or the power-off equipment and the earth. This paper discusses that the personal security line is not suitable for live working, and there are some hidden dangers. Therefore, this article designed a set of 220kV outdoor current transformer anti-induction electricity device, which can effectively solve the above problems.
