A kind of high pressure transformer and distribution power station Integrated Checkout test method

The present invention provides a kind of high pressure transformer and distribution power station Integrated Checkout test method; boosting principle using transformator; protection equipment is controlled by the power transmission of design, applies the construction power supply of 380V in transformer secondary low-pressure side, thus obtaining emulation high-tension electricity in high voltage side of transformer.From transformator feeder cabinet, using emulation voltage, power transmission is simulated to substation bus bar system.After high voltage bus system emulation is subject to electricity, again power transmission is simulated to voltage transformer pt cabinet using emulation high pressure, in order to check the operational factor of PT cabinet, opening winding and triangle winding voltage value, whether the magnitude of voltage of each high-voltage board microcomputer-based intelligent protector meet the requirements.Pass through to simulate power transmission to the voltage transformer pt being connected across on two sections of buses using emulation voltage, defencive function inspection and the test of PT automatic switching of PT microcomputer intelligent protective installation can be carried out.By emulation power transmission, change transformer gear switch, the current values in the record each loop of step down side, high side voltage meter reading value, no-load current characteristic curve during transformator difference gear can be drawn.
