Wuhan UHV specializes in producing series resonators (also known as resonance devices). Next, we will share with you what to do if the resonance device cannot find the resonance point.
If we want to solve the problem of series resonance without finding a resonance point, first of all, we need to understand the idea of series resonance, and then the method can be transformed. "Series" is the method of wiring during testing, and it is also used to adjust the size of voltage and inductance. Resonance is a resonance phenomenon that occurs at one or several frequencies composed of inductance L and capacitance C. That is to say, to generate "resonance voltage" in series resonance, we need to adjust the frequency to make the capacitance and inductance resonance conditions. If you don't understand, you can first look at what series resonance is and what parallel resonance is.
Solution to not finding resonance point:
The main reason for the inability to find the resonance point in small capacity series resonance is that the capacitance is too small and the reactance is too large, resulting in resonance conditions exceeding the resonance frequency and causing the resonance point to not be found. The following two methods can be used to solve this problem:
① Parallel compensation capacitors are connected in the circuit of the series resonance test device.
② Adjust the series and parallel connection methods of the reactor to reduce or increase the inductance.
If none of the above can solve your problem, you can increase the capacitance of the test sample through parallel connection of capacitors, which can also achieve the purpose of resonance testing. Dingsheng Power also kindly reminds customers that when the resonance point cannot be found for series resonance, do not blindly configure it. You can first check the instruction manual, the configuration scheme and electrical parameters provided by our factory, which will facilitate you to complete the testing requirements as soon as possible.
