Description
I. Production Introduction & Features:
Ultra-low frequency insulation withstand voltage test is an alternative test method for the power frequency withstand voltage test.The test procedure is greatly reduced, which is more advantageous than the power frequency test. It can be widely used in the AC withstand voltage test of cables, large high voltage rotary motors and power capacitors.This product combines the advanced technology of modern digital frequency conversion, adopts microcomputer control, step-up, step-down, measurement, protection fully automatic, and can perform manual intervention in the automatic promotion process. Because of the full electronic, the volume small, weight light, large screen liquid crystal display, clear and intuitive, and can display the output waveform, print output test report. In addition, the following features need to be specified:
1.real and accuracy test results of current, voltage, waveform directly get from high voltage lateral sampling.
2.over-voltage protection: device stop runing when output over setting max voltage, time <20ms.
3.over-current protection:double protection for high and low voltage, stop running accurately protect high voltage according to set prameter, stop running when low voltage current over rated current, time <20ms.
4.no need to connect extra protection reactor because of high voltage protection reactor inside booster.
5.due to use high and low voltage closed loop control circuit, output without capacitive rise effect.II. Main Parameter:
