Product introduction:
The XHBP series frequency conversion resonance test device is mainly designed and manufactured for the AC withstand voltage test of primary electrical equipment for substations of 220kV and below. It can meet the AC withstand voltage test of capacitive equipment such as transformer, GIS system, SF6 switch, cable and casing according to the regulations. This series of devices is mainly composed of variable frequency control power supply, excitation transformer, reactor and capacitor voltage divider. After the capacitor divider, the rectifier silicon stack is connected to complete the DC withstand voltage test of the device.
Main Features:
1. Reactors of the same voltage class and same capacity are smaller in size and lighter in weight;
2. The temperature rise is small at rated load;
3. Dry epoxy casting, high mechanical strength, good electrical insulation performance, beautiful and reliable;
4. The frequency conversion control source has a large capacity margin;
5. Strong protection function; good output waveform; good stability;
6. With a variety of working modes, easy to operate; 220V or 380V single-phase power supply, convenient for on-site power.
