Series resonance, also known as variable frequency series resonance test device, is mainly designed and manufactured for AC withstand voltage testing of primary electrical equipment in substations of 220KV and below. Thevariable frequency series resonance test devicecan meet the AC withstand voltage test requirements of capacitive equipment such as transformers, GIS systems, SF6 switches, cables, and bushings according to regulations. The frequency conversion series resonance test device can meet the requirements of both high voltage and low current (current) equipment test conditions, as well as low voltage and high current equipment test conditions The frequency conversion series resonance test device has a wide range of applications .
The series resonant inverter device for frequency conversion is controlled by power, including excitation transformer (transformer), reactor, and capacitive voltage divider. One of the frequency conversion technology control system power supplies can use SPWM digital waveform generation and development chips (also known as microcircuits) specially designed for Chinese imported enterprises. The frequency resolution is 16 bits, and the frequency fineness can reach 0.1Hz between 20-300Hz. The frequency conversion series resonance test detection device also uses orthogonal asynchronous fixed carrier modulation processing to ensure that the output voltage waveform has good performance throughout the entire active frequency range; The power (referring to the amount of work we do on an object in a certain unit of time) part adopts some advanced IPM modules to ensure the stability and safety of the variable frequency series resonance test research device.
When you choose to actively and effectively assist inseries resonancewithin a certain range, we can see that only by having a frequency conversion (VFD) series resonance testing device can the instrument (equipment) slowly connect the series resonators in a certain way by the level of the frequency series resonance testing equipment.
Moreover, by analyzing the customer's feelings after using the variable frequency series resonance test and detection device, it can be found that when facing series resonance, it is easy for us to experience the excitation power (referring to the amount of work done by the object per unit working time) and the important role of information protection in overvoltage, which have significant social significance and value. Only when selecting reactors and capacitive dividers at the level of the frequency conversion series resonance testing device can the active connection between the capacitors and reactors in the sample be observed, and the operation on this capacitance testing device can be gradually eliminated.
Then you can allow every customer to enjoy the frequency (variable frequency) series resonance testing device, gradually experiencing the resonance frequency testing equipment in the development process, so that they can experience its importance in future applications for multiple days. Just when you use and learn about thevariable frequency series resonance test devicethrough this test device, and we are still a company, we have some varying degrees of enthusiasm in improving the working current (Electron flow) through experiments.
This is because the application of series resonance is here, and thefrequency (variable frequency) series resonance test deviceis a valuable role that is very important. However, it is also gradually passing through the series resonance frequency range of the testing equipment, which is enthusiastic about the development of the above internal and continuous states. However, after using the variable frequency series resonance test detection device, you will gradually realize that the variable frequency series resonance test research device has a positive effect on students' work enthusiasm.
