Many users are curious about whether the American box-type substation needs maintenance? How long is its service life? What to pay attention to when using? In fact, after the use of American box-type substation device, 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 shell of the appearance of the disposal of technical problems, should enhance the inspection of its corrosion condition;.
U.S. box-type substation in the tank filled with oil commonly FR3 insulating oil, its ignition point of up to 312 ℃, and has good electrical characteristics, high dielectric strength, smoothness, arc quenching ability to stop the biosynthesis, and therefore a greater level of reduction of the environment and health hazards. FR3 insulating oil is not like the traditional mineral oil as will constitute a precipitate, and the domestic consumption of U.S. box variable is filled with the vast majority of localized Filled with 25# ordinary mineral oil.
In addition, the general condition of the American box-type substation tank are filled with inert gas in the upper part of the tank, in order to avoid the exchange of water in the air to the oil. The domestic American box variable ZGS-100kva may not have enterprises to stop this work, a long time, the performance of the oil should be reduced, coupled with its sealing performance can not reach the request of 7 Psig, so it is necessary to change the oil regularly.
American box variable no oil temperature maintenance, as long as a thermometer to show the oil temperature, when the oil temperature is too high, relying on the insertion of fuses to stop the maintenance, there is a pressure relief valve, used to release the tank is too large pressure. Therefore, should always check whether the fuse can operate normally under these two conditions, and whether the shell can be seepage and leakage of oil phenomenon.
Due to the American box variable tank is exposed to the outside, and therefore should often stop the inspection, in order to avoid collision in the external forces under the damage and the occurrence of oil leakage.
