When we come into contact with the frequency conversion series resonance test device, we will find that many manufacturers are using it. Just by searching online, we can know that this device is used for voltage withstand testing of power equipment. It is a very important test for the power department to detect the ability of power equipment to withstand voltage through voltage withstand testing, so as to maintain safe use of power equipment. So, what is the principle of series resonance testing?
The experimental principle of series resonance is mainly to use an excitation transformer to excite the series resonance circuit, adjust the output frequency of the variable frequency controller, and make the circuit inductance L and the test sample C resonate in series. The resonance voltage is the voltage applied to the test sample.
So how does the series resonance test apply to HV Hipot Electric Co., Ltd. experiment? We know that the main components of variable frequency series resonance include variable frequency power supply, excitation transformer, reactor, and capacitive voltage divider. In the experimental connection, the capacitor of the tested equipment and the series resonant reactor form a series resonant connection. The capacitor voltage divider is connected in parallel to the tested equipment, mainly used to measure the resonant voltage on the tested equipment and provide overvoltage protection signals. The output of the frequency modulation power is coupled to the series resonant circuit through an excitation transformer, providing excitation power for series resonance. Obtain HV Hipot Electric Co., Ltd. experimental results from these data.
Compared with traditional transformer testing, series resonance has made great innovations and breakthroughs. The testing equipment is smaller in size, easier to move and transport, and the operation is greatly simplified, making it more worry free and labor-saving for power workers. The biggest breakthrough is the modular design, which allows the number of reactors to be flexibly configured according to on-site needs, greatly reducing the labor intensity of power workers and improving work efficiency.
