Problems solved by technology

[0003] At present, each functional module of the calibration device based on active breakdown adopts a split structure and cable connection. Too many connection links lead to poor reliability and long preparation time. The cable connection provides a channel for the high voltage to be transmitted to the operation terminal, which increases the operating personnel. Security Risk

Abstract

The invention discloses an integrated wireless control calibrating device for an insulating oil dielectric strength tester, and the device comprises a voltage divider module, a data collection module, a control mainboard, an industrial control computer, a discharge control module and a terminal display module, wherein each module is disposed in a housing. The device can be used for measuring an effective value of an output voltage, peak factors and cutting-off time of the insulating oil dielectric strength tester, employs an integrated design, has a function of wireless control, is simple in operation, and is safe for use.

Description

technical field [0001] The invention relates to the field of electric power safety, in particular to an integrated wireless control calibration device for a dielectric strength tester of insulating oil. Background technique [0002] The insulating oil dielectric strength tester is an instrument used to test the parameter performance of insulating oil in accordance with the requirements of IEC156 and GB507-86, and plays a very important role in electric power safety production. Therefore, it is very important and necessary to calibrate the output parameters (voltage effective value, peak factor and cut-off time) of the insulating oil dielectric strength tester. At present, there are generally two ways to calibrate the insulating oil dielectric strength tester in China. One is to connect the output end of the test to a high-voltage divider, suspend the boost of the tester at the set voltage point, and record the tester at this time. The output indication and true value; anoth...
