1. one kind be used for test transformer (62) method, the transformer include the first inductance (90,92) and with the first inductance(90,92) the second inductance (88) being electrically isolated, first inductance and the second inductance are respectively in first switch circuit and secondIt is connected in switching circuit, this method comprises:

  • Applying DC voltage between first switch circuit point and second switch circuit point (106) in first switch circuit(112);

    The VDCT volts ,direct-current ,test (122) between two switching circuit points is being measured in first or second switching circuit, whereinOne of the two switching circuit points are different from first switch circuit point and second switch circuit point (106);

    AndBased on the transmission performance between DC voltage (112) and VDCT volts ,direct-current ,test (122) come test transformer (62),Wherein, the first inductance in first switch circuit (90,92) is additionally the test switching circuit of scheduled transmission performanceA part, the test switching circuit have at least two resistance (116,118), at least two resistance (the 116,118) structureVoltage divider and first inductance (90,92) is connected in series between at least two resistance (116,118), whereinDC voltage (112) and VDCT volts ,direct-current ,test (122) are respectively applied to test switching circuit and measure in test switching circuitIt takes,Wherein, the transmission performance between DC voltage (112) and VDCT volts ,direct-current ,test (122) passes through at least two resistance(116,118) it determines.
