The AC withstand voltage resonant device is mainly designed and manufactured for the AC voltage withstand test of primary electrical equipment in substations below 220kV. Can meet the AC withstand voltage test requirements for capacitive equipment such as transformers, GIS systems, SF6 switches, cables, and bushings according to regulations. It can meet the requirements of equipment testing conditions for high voltage and low current, as well as low voltage and high current, and has a wide range of applications. It is an ideal withstand voltage equipment for high voltage testing departments and power installation and maintenance engineering units at the prefecture, city, and county levels.
Configuration List of AC withstand Voltage Resonant Device:
The AC voltage resistant resonant device mainly consists of a variable frequency control power supply, an excitation transformer, a reactor, and a capacitive voltage divider. The variable frequency control power supply adopts an imported specialized SPWM digital waveform generation chip with a frequency resolution of 16 bits. The frequency fineness can reach 0.1Hz between 20-300Hz. At the same time, it adopts orthogonal asynchronous fixed carrier modulation to ensure good output waveform throughout the entire frequency range; The power section adopts advanced IPM modules to ensure the stability and safety of the instrument.
Product characteristics of AC withstand voltage resonant device:
1. Reactors of the same voltage level and capacity have smaller volume and lighter weight; Low temperature rise at rated load; Adopting dry epoxy casting, it has high mechanical strength, good electrical insulation performance, and is aesthetically pleasing and reliable.
2. The variable frequency control series resonance has a large capacity margin; Strong protection function; Good output waveform; Good stability; Having multiple working modes and easy operation; Adopting 220V or 380V single-phase power supply for convenient on-site power supply.
3. Flexible configuration. Different types of reactors can be selected to meet the requirements of different test samples, achieving multi use and high cost-effectiveness.
