The invention discloses an insulation simulated experimental device which comprises a three-phase voltage regulator, a rectifier bridge, a filtering capacitor, an inversion bridge, a resonance transmission unit, a high voltage transformer and a host computer. The input end of the three-phase voltage regulator is connected with a power supply, and the output end of the three-phase voltage regulatoris connected with the input end of the rectifier bridge; the filtering capacitor is arranged in the output end of the rectifier bridge in parallel, and the output end of the rectifier bridge is connected with the input end of the inversion bridge; the output end of the inversion bridge is connected with the input end of the resonance transmission unit; the output end of the resonance transmissionunit is connected with the input end of the high voltage transformer, and the output end of the high voltage transformer is connected with a tested sample; and the host computer is connected with atleast one selected from the power supply, the three-phase voltage regulator, the rectifier bridge, the inversion bridge, the high voltage transformer and the tested sample, and used to realize relatedcontrol and signal collection when the insulation performance of the tested sample is tested. Insulation test of related products can be realized rapidly and effectively, a test result is more accurate, and the security is higher.
