This series devices are designed for AC withstand voltage test of substation primary equipment under 550KV or below, mainly composed of variable-frequency power supply, exciting transformer, reactor and capacitive Voltage divider
Features:
Easy to operate, two working modes: manual and automatic
Can set Test Voltage, frequency range, protective current and operating time
Dry type epoxy cast, high mechanical strength, good insulation, nice and reliable.
Adjustable capacity of frequency control source.
With 220V or 380V single phase power, convenient for on-site power sourcing.
Flexible configuration. Different type reactors for option to meet different test object requirements.
Smaller size, lighter weight compared with same voltage level same capacity reactor.
Small temperature rise at rated load. Strong protection, good stability. Multiple functions, cost effective.
Parameter:
Rated output voltage: 0 - 1000kV
output frequency: 30 ~ 300Hz
Waveform: pure sine wave, THD <1.0%.
Duty Cycle: Continuous working time 60mins one time at full power output.
Quality factor: 30-90
Frequency adjustment sensitivity: 0.1Hz
instability <0.05%.
Power Supply: 380/220V±15%, 50Hz ± 5%. - or customized
