100~10000kV series complete set of impact voltage (current) test devices with various capacity. It also provides a variety of waveform series complete sets of impact voltage (current) generators. The impact test device is mainly composed of: generator body, wave cutter, voltage divider, four-component console (the console is divided into microcomputer type and ordinary type), digital waveform recording system, etc.

Product Features

Standard lightning impact, lightning cutoff wave, operational impact and user-required test samples, including transformers, reactors, transformers and other high-voltage electrical appliances, high-voltage thyristor valve SVC (HVDC), power cables, various high-voltage insulators, casings, etc. Various types of shock voltage tests for shock waves.

Technical parameters

 1. Host part 

1. LVG series impact voltage testing system, combined with Swiss Haefely structure, is suitable for low voltage grade products, bilateral asymmetric charging, wave head and wave tail resistors can be used in parallel, and there is a discharge gap between wave tail resistors, which is used to To improve the synchronous discharge performance, the wave regulating resistance is a plate-shaped structure, and the inductive winding method is not allowed to be installed in a closed insulating cylinder and continuously provide filtered air. The ball gap is not easily affected by environmental changes and has stable discharge; it can produce various waveforms such as 1.2/50μs.  

2. Voltage level and energy 

Voltage level 100kV - 1800kV 

Stage voltage 100kV  

Energy 1.25kJ - 168.75KJ 

2. Voltage divider 

1. Weak damping capacitor voltage divider for measuring impact: 50kV - 1800kV 

2. High-precision fast response resistor divider for measuring steep waves: 50kV - 500kV 

3. Wave cutoff device 

1. Multi-stage ball gap wave cutoff device: 100kV - 1800kV 

2. Single-stage ball gap wave cutoff device: 100kV - 1800kV  

4. Control system Main functions of control system: 

1. Manual/automatic charging, manual/automatic trigger, manual/automatic pitch tracking, manual/automatic polarity conversion;  

2. Charging voltage display, charging current display, discharge ball distance display, discharge number display;  

3. The ignition pulse delay can be adjusted.   

4. Control system: Combined with Swiss Haefely control system; computer control, it has high reliability and stability; simplified control system and automatic multifunction control system for choice.
