Abstract

This paper analyzes the leakage mechanism of gas tank of gas insulated switchgear

and proposes a leakage rate calculation method. The helium leakage detector’s principle

structure

advantages and disadvantages

maintenance

calibration

and detection process

as well as attentions

are discussed.It is concluded that the application of the helium leakage detector to the gas tank filled with SF6

nitrogen or dry air can help to obtain more accurate leakage rate and leakage point.
