[0002] At present, the oil level gauge of box transformer is faced with unique challenge in the winter environment of northeast area. Specifically, the oil level gauge in this environment often encounters the problem of sealing performance decline of rubber sealing ring. Because low temperature causes rubber material to harden and shrink, the sealing effect is greatly discounted, so that the outside water vapor has the opportunity to penetrate into the inside of oil level gauge.

[0003] Once the water vapor invades, it will quickly condense into ice under low temperature condition or form fog in the inside of oil level gauge, which greatly hinders the accurate observation of operation and maintenance personnel to the oil level of oil pillow. The window of oil level gauge is shielded by frost or fog, so that the real-time state of oil level becomes blurred, and it is difficult to obtain accurate information in time. More seriously, when the oil level gradually decreases due to leakage or other reasons, if the oil level gauge is frozen or fogs and cannot be found in time, it may cause the oil level of transformer to be too low, and then affect the normal operation and even cause safety hazards.
