Applications:
This lightning impulse test system is used for carrying out standard lightning impulse voltage full wave and chopping wave test on power transformer, HV apparatus such as high voltage switchgear, power capacitors, clearance, bushings, and CT/PT.

Technical Data

Nominal voltage: 900kV

Rated voltage: 150kV

Nominal energy: 20.2kJ

The total impact capacitance: 0.05 microfarad (single pulse capacitor 0.6microfarad / 75kV, a total of 12).

The total number of levels: 6

Standard waveform parameters:

Standard lightning impulse voltage full wave,

The head of wave±1.2/30%ms The tail of wave:50ms±20%

Voltage utilization factor >85% (more than 90% when no load 300PF);

System structure

The structure of the system is shown in Figure 2:

The part surrounded by the green line in Figure 2 is an integrated measurement and control system. The lower position machine is directly connected with the impulse voltage generator body, the power supply and the intercepting device. All the bottom operations such as relay opening and closing are controlled by the lower position machine, and the upper computer is connected to the lower position machine through the optical fiber, and sends the commａnd to the lower position machine to drive the body and the power supply. The chopper device continuously collects data and acquires the current state, and simultaneously transmits the collected data to the upper computer without interruption, and the voltage and current signals of the voltage divider are connected to the upper computer through the acquisition module
