[0031] The test prototype is used to produce forced contamination on the insulator 7 after detonation;

[0032] Insulator 7 is a high voltage output terminal, and high voltage flashover occurs when it is contaminated.

[0033] like Figure 2 As shown, the AC test power supply device includes a power switch cabinet, a voltage stabilization output subsystem, a power frequency protection resistor 5 and a computer-controlled test device 8. The power switch cabinet, the computer-controlled test device 8, the power frequency protection resistor 5 and the insulator 7 are electrically connected in sequence;

The column voltage regulator 2 is connected between the front-stage power switch cabinet 1 and the rear-stage power switch cabinet 3, and the rear-stage power switch cabinet 3 is connected to the power frequency pollution-free partial discharge transformer 4. The high-voltage output end of the power frequency pollution-free partial discharge transformer 4 is connected in series with the power frequency protection resistor 5 and the power frequency capacitor voltage divider 6 in sequence and then grounded. The high-voltage end of the power frequency capacitor voltage divider 6 is connected to the test insulator 7, and the computer-controlled test device 8 is connected in parallel with the front-stage power switch cabinet 1, the column voltage regulator 2, the rear-stage power switch cabinet 3, the power frequency pollution-free partial discharge transformer 4 and the power frequency capacitor voltage divider 6. The voltage is controlled by adjusting the forward and reverse rotation of the motor on the column voltage regulator 2 to stably output a high voltage of up to 150kV. The power frequency pollution partial discharge transformer realizes compensation, boosting and harmonic suppression. The compensation part refers to the compensating reactor in the circuit.
