The reactor adopts multiple separate designs, which can meet the requirements of high voltage and low current equipment testing conditions, as well as the requirements of low voltage AC withstand voltage testing. It has a wide range of applications and is an ideal withstand voltage equipment for high voltage testing departments and power installation and maintenance engineering units at the prefecture, city, and county levels.

Only by effectively detecting the insulation defects of high-voltage electrical equipment can the operation of the entire power system be better maintained, and such withstand voltage tests are more effective. Because of large generator sets, main transformersGISSwitches, power cables, and other large capacity electrical equipment have insulation tolerance within a certain frequency range, which is equivalent to the power frequency withstand voltage. Therefore, it is necessary to use a series resonant withstand voltage test device that can be frequency converted for testing.

So under what circumstances is it necessary to use a variable frequency series resonant AC withstand voltage test device? Specifically, when the withstand voltage test cannot truly reflect the distribution of the electric field during on-site testing, it is difficult to detect internal defects in high-voltage electrical equipment. 2、 When using DC withstand voltage equipment, the DC voltage significantly reduces the partial discharge inside the high-voltage electrical equipment, making it difficult to detect internal insulation defects. 3、 When conducting a power frequency AC withstand voltage test, the actual operating voltage waveform reflected by the test is consistent with the transient voltage rise that occurs during operation, and there is no issue of equivalence. When power workers encounter the above phenomena in their actual work, it is necessary to use the Hangtai Power Variable Frequency Series Resonant AC Voltage Withstand Test Device for more practical and effective detection of insulation defects in the test sample.
