SF 6 equipment has leakage due to various reasons. The longer the equipment operates, the more serious the leakage is. When the equipment gas leaks to the set air replenishment value, the air replenishment alarm signal will be sent. It can be seen from the SF 6 gas temperature pressure relationship table that the temperature change has a great impact on the pressure value. Although the equipment popularizes the SF 6 density meter or SF 6 density relay with temperature compensation, the compensation system needs to achieve temperature compensation through a long time, resulting in the distortion of the pressure value counted by the operation and maintenance personnel. Therefore, the temperature difference between winter and summer is large, and more alarm signals are obtained. At this time, there are great potential safety hazards in air replenishment. This paper introduces in detail a SF 6 gas leakage prediction device in substation, which can effectively solve the above problems in substation.
