The series resonance under HVHIPOT can help many power workers conduct various power tests more conveniently.
In the testing and inspection work of the power system, the frequency conversion resonance test device plays a crucial role. The frequency conversion resonance test device produced by HVHIPOT has become the first choice for many power enterprises due to its excellent quality and advanced technology.
For the voltage withstand test of the generator, the device model should be determined based on the capacity and voltage level of the generator. The DFVF3000-100/36 device of HVHIPOT can be used for power frequency withstand voltage tests of 600MW and below generators, with phase capacitance ranging from 0.1-0.25 μ F. It can also be used for 1.5km tests of 10kV and 300mm ² cables. This reflects the universality and flexibility of the HVHIPOT frequency conversion resonance test device, which can meet the testing needs of various power equipment.
When conducting AC withstand voltage tests on GIS and SF6 switches, such as the 110kV GIS, the DFVF3000-250/200 device from HVHIPOT can be selected. It is equipped with 5 40kV reactors, which can not only complete the 110kV GIS test, but also perform withstand voltage tests on other equipment such as 35kV and 300mm ² cables for 1km.
Secondly, when selecting, parameters such as test voltage, frequency, and time should also be considered. The frequency range of the frequency conversion resonance test device for HVHIPOT is 30-300Hz, which can meet the testing frequency requirements of different power equipment. The resonant voltage waveform is a sine wave with a waveform distortion rate of less than 1.0%, which ensures the accuracy and reliability of the test results.
In addition, the frequency conversion resonance test device of HVHIPOT has complete protection functions, such as overvoltage, overcurrent, IPM and discharge protection, which can effectively protect personal and equipment safety. The device is easy to operate, with a blue screen displaying test data and status, and real-time operation step prompts, greatly improving test efficiency.
In short, the frequency conversion resonance test device of HVHIPOT provides an ideal choice for the withstand voltage test of power equipment with its rich models, excellent performance, and reliable quality. When selecting a frequency conversion resonance test device, fully considering the characteristics and advantages of HVHIPOT products, combined with the actual needs of the test subjects, the most suitable test device can be selected to ensure the safe and stable operation of the power system.
