ACCELERATED DEGRADATION TESTER FOR INSULATION OF ELECTRICAL MACHINERY, HAVING A PEAK-PEAK IMPULSE VOLTAGE CONTROL FUNCTION, AN IMPULSE REPEATED FREQUENCY CONTROL FUNCTION, AND A JUMP VOLTAGE CONTROL FUNCTION

摘要

PURPOSE: An accelerated degradation tester for insulation of electrical machinery is provided to implement various controls while testing insulation resistance through accelerated degradation during a certain time.;CONSTITUTION: An accelerated degradation tester for insulation of electrical machinery includes a frequency controller(200), an impulse voltage generator(300), and a jump voltage controller(500). The frequency controller generates impulse repetition frequency information applied to electrical machinery and an apparatus(100) and outputs it as a gate signal trough a circuit. The impulse voltage generator calculates the frequency of the gate signal supplied from the frequency controller and converts a DC voltage into an impulse voltage having the calculated frequency. The jump voltage controller supplies the converted DC voltage to the impulse voltage generator and applies jumped voltage which is generated from the impulse generator to an electric appliance.;COPYRIGHT KIPO 2011
