The series resonance withstand voltage test device consists of several components: variable frequency power supply, excitation transformer, reactor, and capacitive voltage divider. Each part performs its own function and has its own advantages. Series resonance is also called variable frequency series resonance, because the outstanding advantage of this equipment in power system applications is that it has a variable frequency power supply, which is also the main unit. The variable frequency power supply has a small capacity, which reduces the power required for the test, making power tests safer and more reassuring. The overall volume and weight of the equipment are reduced, making it more convenient to move in actual use. The modular combination of reactors greatly increases the flexibility of power tests. Most importantly, the variable frequency series resonance withstand voltage test device has very powerful protection functions during power tests, allowing the entire power test to be conducted in a very safe environment. For example, the device has the function of preventing large short-circuit currents from burning the fault point, so that high-voltage withstand tests can easily and quickly find insulation weaknesses while eliminating the concern of short-circuit currents burning the fault point. The device can also effectively prevent harmonic peaks from causing non-breakdown of the test object, and there will be no recovery overvoltage. Therefore, it is very safe during high-voltage withstand tests in power systems.
In high-voltage withstand tests in power systems,the series resonance withstand voltage test device is the optimal choice for many power workers, so series resonance is worth choosing!
