No matter what causes the trip of baoding dry transformer, on the one hand, the load should be transferred as soon as possible and the operation mode should be changed. On the other hand, find out what kind of protection action. The submersible oil pump should be stopped immediately, and all protective actions should be checked to see if there is any normal phenomenon. When tripping, whether the baoding dry-type transformer is overloaded, whether the feed line is jumping off at the same time.
(1) if the fault of transmission and feed lines and other equipment affects the over-level trip, if the insulation resistance of the baoding dry-type transformer and all external conditions are normal and the gas relay is free of gas, the transformer operation can be resumed after the fault lines (equipment) are removed.
(2) when overloading causes trip, the main transformer will be input after load reduction;
(3) there is no sign that the protection has not been dropped, and there is no short circuit in the system, and all aspects are normal. At this time, the protection secondary circuit and switch mechanism of the relay should be checked to see whether the relay operates by mistake. If the reason cannot be found out, the insulation resistance and dc resistance of the transformer should be measured, the free carbon of the transformer oil should be checked, and then the operation can be resumed according to the analysis. It is prohibited to put the baoding dry transformer into operation if any abnormal phenomenon is found.
