The application ofseries resonance test devicein high-voltage withstand voltage test greatly reduces the difficulty of high-voltage withstand voltage test. Traditional high-voltage withstand voltage testing has disadvantages such as large testing equipment, difficult mobility, and slow testing efficiency. The series resonant high-voltage withstand voltage test device overcomes the shortcomings of traditional high-voltage withstand voltage tests and has made significant improvements on this basis, making high-voltage withstand voltage tests more efficient.
For the AC withstand voltage test of electrical equipment such as 220kV high-voltage bushings, main transformers, and isolating switches, the series resonant withstand voltage test device has a wide range of applications and is also a very practical and easy-to-use withstand voltage test equipment for various high-voltage testing departments and power decoration testing engineering units.
Theseries resonant withstand voltage test devicehas the advantages of small power capacity, small equipment volume and weight, improved output voltage waveform, prevention of large short-circuit current burning out fault points, and failure to recover from overvoltage. Especially by improving the output waveform and preventing large short-circuit currents from burning out the fault point, it does not have the advantage of restoring overvoltage, making high-voltage withstand voltage testing very safe and reliable. This is because the resonant power supply is a resonant filtering circuit, which can not only improve the waveform distortion of various voltages, but also obtain good sine waves, thereby preventing harmonic peaks from penetrating the measured object. When the test is in series resonance state, when the insulation weak point of the tested object is broken down, the circuit will immediately resonate, and the circuit current will quickly drop to a small multiple of the normal test current, so that series resonance can quickly find the insulation weak point and prevent the hidden danger of short-circuit current burning out the fault point. When the tested object breaks down, the high voltage immediately disappears due to the loss of resonance conditions, and there will be no recovery overvoltage.
Therefore, the application ofseries resonance test devicein high-voltage withstand voltage test, due to the advantages of series resonance, makes high-voltage withstand voltage test safe, reliable, simple and efficient. Therefore, the series resonance test device is a very practical and reliable testing equipment in high-voltage withstand voltage testing!
