Bangladesh Power Company successfully used a series resonance provided by our Wrindu company. This is the second time that Bangladesh Power Company has trusted and chosen our equipment after the first cooperation. Based on the good experience of the first cooperation, Bangladesh Power Company directly ordered a whole set of series resonance devices to improve the stability and reliability of its power system.
Advantages of series resonant power supply in power system applications:
competitive advantage
The company conducted a competitive advantage analysis to identify its strengths and weaknesses compared to its rivals.
1. The required power capacity is greatly reduced.
The series resonant power supply uses the resonance of the resonant reactor and the capacitor of the test object to generate high voltage and large current. In the entire system, the power supply only needs to provide the active consumption part. Therefore, the power required for the test is only 1/Q of the test capacity.
2. The weight and volume of the series resonance are greatly reduced.
In the series resonant power supply, not only are the bulky high-power voltage regulator and the ordinary high-power power frequency test transformer eliminated, but also the resonant excitation power supply only needs 1/Q of the test capacity, which greatly reduces the system’s weight and volume, generally 1/5-1/10 of the ordinary test device.
3. Improve the output voltage’s waveform.
The resonant power supply is a resonant filter circuit that can improve the output voltage’s waveform distortion, obtain a good sine waveform, and effectively prevent the harmonic peak from erroneously breaking down the test object.
4. There will be no recovery overvoltage.
When the test product breaks down, the high voltage disappears immediately due to the loss of resonance conditions, the arc is extinguished immediately, and the recovery voltage re-establishment process is very long. It is easy to disconnect the power supply before reaching the flashover voltage again.
