The series parallel resonance withstand voltage test device is composed of several parts such as a variable frequency power generator, a high-voltage reactor, an adjustable reactor, a capacitive voltage divider, and an excitation transformer. The series parallel resonance withstand voltage test device is suitable for preventive testing and handover testing of large capacity, high-voltage capacitive samples such as power cables, power transformers, hydroelectric generators, thermal generators, GIS switches, etc. Its functional characteristics are significant and it is widely used in industries such as power, metallurgy, petroleum, chemical, and water conservancy.
The testing principle of the series and parallel resonance withstand voltage test device is to achieve resonance testing by adjusting the output frequency of the variable frequency power generator or by adjusting the inductance of the reactor. According to the market types, the series and parallel resonance withstand voltage test devices are currently divided into two categories: variable frequency and inductive. The characteristics of the series and parallel resonance withstand voltage test device include high stability and reliability, powerful automatic tuning function, support for multiple test modes, friendly system human-machine interaction interface, and complete protection function. Based on its characteristics, it has the advantages of small power supply capacity, small equipment weight and volume, improved output waveform, prevention of short-circuit current burns, and no overvoltage recovery in power system applications.
Instrument features
1. The device has protection functions such as overvoltage, overcurrent, zero start, and system detuning (flashover). The overvoltage and overcurrent protection values can be set according to user needs, and the flashover protection will be activated when the test sample flashover to protect the product.
2. The entire device is lightweight and easy to use on site.
3. The device has three working modes, which are convenient for users to flexibly choose according to the on-site situation and improve the testing speed. The working modes are: fully automatic mode, manual mode, and automatic tuning manual boost mode.
4. It can store and print data in different locations, and the stored data numbers are numerical, making it convenient for users to identify and search.
5. When the device automatically scans the frequency, the starting point of the frequency can be set arbitrarily within the specified range, and the LCD screen displays the scanning curve, making it convenient for users to intuitively understand whether the resonance point has been found.
6. Adopting DSP platform technology, it is convenient to add or remove functions and upgrade according to user needs, making the human-machine exchange interface more user-friendly.
