High Voltage Switchgear five anti: 1, high voltage switchgear vacuum circuit breaker inside the car after closing the test position, the car can not enter the work breaker position. (To prevent closing with load) 2, High Voltage Switchgear ground knife within close position, the car can not enter the circuit breaker closing. (With a ground wire to prevent closing) 3, high voltage switchgear vacuum circuit breaker in the closing work within and panel back door and door lock with a mechanical knife on the ground. (To prevent mistakenly charged interval) .4, vacuum circuit breakers at work within high voltage switchgear closing low voltage, grounding knife can not be put together. (Prevent the charged closing earthing wire) 5, the vacuum circuit breaker at work within high voltage switchgear closing run low voltage switch manufacturers, can not exit the car breaker's working position. (To prevent negative Hera Knife) power transformer economic operation in ensuring the safe operation of the transformer and meet the basic power quality and reliability users on low voltage purchase, take advantage of substation equipment conditions, select the preferred mode of operation high voltage transformer switchgear, transformer itself reduce energy loss and improve the power factor of the power side, to achieve the goal of reducing energy loss. Power supply load and transformer capacity and determine the number of units, related to the transformer economic operation mode; the implementation of the transformer economic operation of the substation transformer station number, capacity and transformer own performance and loss parameters are closely related, it is built in to ensure safe and reliable power supply premise A comprehensive economic and technical activities, through the power transformer accessible from the design selection, running the entire decommissioning process; in the substation construction, expansion and transformer capacity increase is necessary to consider their associated factors and conditions; the implementation of transformer economic operation, the transformer and substation equipment itself and in general should have the following conditions are met transformer design and selection should be given full consideration.
