A power rush method of testing for steel disc resistance, comprises the steps:
Step 1: first first guarantee that the first contactor in test platform, the second contactor all disconnect;
Step 2: closed the first contactor subsequently, by control rectifier not by voltage lifting in energy capacitance set; Operation three phase rectifier, by controlling three-phase reorganizer and then the stable firmly voltage at energy capacitance set two ends, to guarantee that capacitance voltage drops unlikely too serious after the second contactor closure;
Step 3:, closed the second contactor, thus realize the instantaneous power shock-testing to resistance.

A power rush method of testing for steel disc resistance, comprises the steps:
Step 1: first first guarantee that the first contactor K1 in test platform, the second contactor K2 all disconnect;
Step 2: closed the first contactor K1 subsequently, by control rectifier not by voltage lifting in energy capacitance set; Operation three phase rectifier, by controlling three-phase reorganizer and then the stable firmly voltage at energy capacitance set two ends, to guarantee that capacitance voltage drops unlikely too serious after the second contactor K2 closure;
Step 3: closed the second contactor K, thus realize the instantaneous power shock-testing to resistance R.
According to the real work situation of steel disc resistance, determine the size of required dash current, and then determine the voltage of releasing on electric capacity by U=I*R, and then pass through
determine the size of step-up transformer secondary output voltage.As: in practical application operating mode, the dash current being subject on resistance is about 1200A, and resistance value is 1 Ω.From above-mentioned condition, voltage Uc ≈ 1200V on electric capacity, and then known transformer secondary voltage
≈ 848.5V.According to actual test platform device parameters situation, if transformer secondary cannot reach so high voltage, can suitably reduce resistance value R(because object is steel disc resistance, only need to guarantee steel disc unlikely Bending Deformation after being impacted, part that can be removed steel disc reduces resistance to be tested).
