Many users are very curious, American box-type substation need to be maintained? How long is its service life? What should be paid attention to when using? In fact, after the use of American box-type substation, it is basically no maintenance, but the domestic consumption of products due to a variety of reasons, the maintenance of box-type substation is indispensable.

Due to the appearance of the shell disposal technical problems, should strengthen the inspection of its corrosion condition;

The oil filled in the oil tank of American box-type substation is generally FR3 insulating oil, whose ignition point can reach 312 ℃, and has good electrothermal characteristics, high insulation strength, good smoothness, strong arc extinguishing ability, and can stop biosynthesis, thus greatly reducing the harm to the environment and Ankang. FR3 insulating oil does not form sediment like traditional mineral oil, while most of the American box changes consumed in China are filled with 25# ordinary mineral oil.

In addition, under normal conditions, the upper part of the tank of the American box-type substation is filled with inert gas to avoid the exchange of water in the air to the oil. However, domestic American box transformer ZGS-100kva may not have any enterprises to stop this work. As time grows, the performance of the oil will decrease. In addition, its sealing performance cannot meet the request of 7 Psig, so regular oil change is necessary.

There is no oil temperature maintenance for American box transformer. Only a thermometer is needed to show the oil temperature. When the oil temperature is too high, the maintenance is stopped by plug-in fuse and there is also a pressure release valve to release too much pressure in the oil tank. Therefore, it should always check whether the fuse can operate normally under these two conditions, and whether the shell can leak oil.

As the tank of the American tank is exposed to the outside, it should be stopped frequently to avoid oil leakage due to damage caused by external collision.
