What operation sequence should be observed when the distribu

    When operating transformer, in order to prevent arc burn accident, to avoid load pull. When opening and closing, first pull the low voltage branch switch, then pull the low voltage main switch, and finally pull the high voltage switch under the condition of no load of the transformer. When the switch is closed, it is the opposite. It should be noted that transformer no-load operation can only be operated when the transformer is tested. Long-term no-load operation of the transformer is not allowed for no reason. Long-term no-load operation will damage the transformer.
