As mentioned earlier, due to the circuit specificity of series resonance (also known as cable withstand voltage test device), it is different from ordinary dynamic circuits and has many characteristics. So, what are its specific application ranges?
So far, China’s communication industry has done very well. However, due to the fact that HVHIPOT communication is carried out through satellites and signal stations in each region for signal transportation, developed cities have a comparative advantage in their areas, so the signals they receive are much better. However, for some mountainous areas, due to the regional situation, the signal reception is poor or the signal is acceptable but still unstable. Therefore, the problem of unstable signals is also a thorny issue that many communication industry personnel need to solve. So the relevant characteristics of series resonance can be applied in the communication industry. By combining series resonance with the communication industry, it can make the signals transported in HVHIPOT communication industry more stable and durable. Even in areas with less obvious advantages or underdeveloped communication, they can receive very stable communication signals.
Also, regarding its application in HVHIPOT high-voltage testing and withstand voltage experiments, such as HVHIPOT variable frequency series resonance experiment, we have applied this special feature to HVHIPOT high-voltage technology and conducted withstand voltage equipment testing for transformers and other power equipment. By using this device, we can effectively detect and solve extreme defects in HVHIPOT high-voltage products, which can improve the safety of HVHIPOT high-voltage work.
Finally, regarding series resonance, its characteristics in the radio industry can be applied to channel selection in radios. By combining it with radio technology, channel selection and switching can be achieved.
