HZXB-1000kVA/500kV Series Resonant Test Device
Overview
The Series Resonant Test Device is mainly designed and manufactured for 10kV, 35kV, 110kV, 220kV cables, 110kV / 80000 kVA main transformer fully insulated, 110kV, 220kV GIS, switches and circuit breakers. The reactor adopts an independent and segmented design, which can meet the requirements of high-voltage low-current equipment testing as well as low-voltage AC voltage testing for applications such as 10 kV cables. With a wide range of applications, it is the ideal high-voltage testing equipment for ground, city, county-level power departments, and power installation and repair engineering units.
It mainly consists of a variable frequency control power supply, an excitation transformer, a reactor, and a capacitive voltage divider.
