HV Hipot Electric Co., Ltd. specializes in producing series resonance (also known as series resonance test withstand voltage device). Next, we will share an introduction to series resonance with you.
The series of problems related to series resonance mainly focus on the design and manufacturing of information AC withstand voltage tests for primary electrical engineering equipment in substations of 220KV and below. Can meet the AC withstand voltage test requirements for capacitive equipment such as transformers, geographic information systems, SF6 switches, cables, and bushings. The development conditions for testing equipment that can meet high voltage and low current requirements, as well as the technical testing and research conditions for equipment with low voltage and high current requirements, have a wide range of applicability. However, there is no ideal voltage resistant equipment available for high voltage testing management departments and power installation and maintenance engineering construction units at the prefecture, city, and county levels.
Series resonance is mainly composed of variable frequency control power supply, excitation transformer, reactor, and capacitive voltage divider. The power supply of the variable frequency technology control system can use the SPWM digital waveform generation and development chip imported from China, with a frequency resolution of 16 bits. The frequency fineness can reach 0.1Hz between 20-300Hz. At the same time, the orthogonal asynchronous fixed carrier modulation processing method is adopted to ensure that the output voltage waveform has good performance throughout the entire working frequency range; The power and some advanced IPM modules are used to ensure the stability and safety of the experimental instrument company.
Main features:
Compared with similar products in HV Hipot Electric Co., Ltd. country, this series of equipment has a series of key advantages:
1. Reactors with the same voltage level and capacity have smaller volume changes and lighter weight; Low temperature rise at rated working load; Adopting dry epoxy casting, the mechanical design has high strength, the electrical equipment insulation technology has good performance, and it is beautiful, safe and reliable.
2. The variable frequency speed control power supply has a large capacity margin, strong protection function, good output waveform, good stability, diverse working modes, and easy operation. It adopts 220V or 380V single-phase power supply, which is convenient for on-site power collection.
3. The device is fully configured. Different types of reactors can also be selected to meet the testing requirements of different users, achieving multi use and high cost-effectiveness. Different specifications can be customized according to customer requirements, making it the best choice for users!
