Product Detail
Transformer GIS SF6 switch CT/PT insulator bus bar cable bushing and others capacitive devices are the common primary electric equipments.
Product Description
Transformer GIS SF6 switch CT/PT insulator bus bar cable bushing and others capacitive devices are the common primary electric equipments.
The complete set of frequency conversion series resonance test equipment is mainly used for ac withstand voltage test of cross-linked cable, hydraulic generator, main transformer, bus GIS etc.
The complete set of frequency conversion series resonance test equipment is mainly composed of frequency conversion control power, supply excitation ,transformer reactor ,capacitor voltage divider and compensation capacitor (optional).
product features
1,The reactor of the same voltage grade and capacity has smaller volume and lighter weight. Small temperature rise at rated load; Dry pouring high mechanical strength good electrical insulation beautiful and reliable.
2,Large capacity margin of frequency conversion power control box; Strong protection function; Good output waveform; Good stability; With a variety of working modes easy to operate; Single-phase 220V or three-phase 380V input power supply is common which is convenient for on-site power collection.
3,Flexible configuration. Can choose different types of reactor meet the requirements of different test products achieve a multi-purpose cost-effective.
