Baoding dry type transformer no matter what causes tripping, on the one hand should transfer the load as soon as possible, change the operation mode. On the other hand, find out what kind of protective action. The submersible pump should be stopped immediately, the protection action should be checked and there is no normal phenomenon, the transformer is not overloaded when tripping, and the feeder line is not tripping at the same time. Apart from confirming that the wrong action can be closed immediately, the insulation resistance should be measured and judged according to the following situations:
(1) if the transformer insulation resistance and the external environment are all normal and the gas relay has no gas, the fault line (equipment) can be cut off and the transformer can be restored to operation.
(2) tripping due to excessive load, the main transformer is input after load reduction;
(3) the system is free of short circuit and normal in all aspects. At this time, check the secondary circuit of relay protection and switch mechanism for wrong operation. If the wrong operation is done, the transformer can be restored after eliminating the defect. If the cause cannot be found, the insulation resistance and dc resistance of the transformer should be measured, the free carbon of the transformer oil should be checked, and the operation can be resumed according to the analysis. The transformer shall not be put into operation if any abnormal phenomenon is found.
