pin transformerStandard for tripping treatment. When the pin transformer trips, the maintenance shall be stopped according to the on-site rules and regulations, the maintenance action state and the phenomenon when the accident occurs shall be analyzed, the accident state shall be judged, and the treatment shall be stopped. , gas overhaul and differential overhaul should trip at the same time. Do not send electricity before.
When the differential maintenance of the pin transformer trips at the same time, check the appearance of the main pin transformer, notify the working area, maintenance, relay and other relevant personnel to rush to the site, stop the inspection of the primary and secondary circuits of the pin transformer, and stop the judgment. Pin transformer oil and gas characteristics. And through the DC resistance and isolation experiments. After proving that there is no problem with the pin transformer and its maintenance control circuit, it can be forced to stop once. When the system is in urgent need, there is no abnormality in the external inspection and insulation test of the main pin transformer, and the test can be sent once with the approval of the chief engineer. When the pin transformer gas maintenance action trips, the test Delivery can only be made after it is proved that there is no problem with the gas maintenance fault or the pin transformer.
When the over-current maintenance action of the pin transformer trips, the pin transformer and its load state and the maintenance action state of the distribution line shall be checked and analyzed. If the trip is caused by a straight through problem, there is no need to check. After the problematic line switch is disconnected, stop supplying power to the pin transformer, distribute the non-problematic distribution lines one by one, and notify the work area for experimental inspection.
