Problems solved by technology

[0003] The AC withstand voltage test mostly uses milliampere meter readings, that is, reading the capacitive current value of the object under test, which is an important part of the test. According to the characteristics of the AC withstand voltage test, the current of the object under test is small and low when there is no breakdown. When the voltage is low, the instrument is required to accurately measur

Abstract

The invention discloses an insulation voltage endurance testing device, and the device comprises a voltage bearing testing apparatus which is used for accommodating to-be-measured insulating objects,and achieving the high-degree insulation between the to-be-measured insulating objects and the high-degree insulation between the to-be-measured insulating objects and the ground; a step-up apparatuswhich is electrically connected with the to-be-measured insulating objects, provides a test high voltage for the to-be-measured insulating objects, and can automatically control the step-up speed andstep-down speed; and a detection apparatus which is electrically connected with the voltage bearing testing apparatus, has an overcurrent protection function and an overvoltage protection function, and is used for detecting a leaked current, and detecting whether the insulating performances of the to-be-measured insulating objects meet the standard or not. The device can accurately measure and read the data, protects the personal safety of a tester, protects an instrument from being damaged, improves the testing safety and efficiency, and is a simple and convenient, efficient and ideal insulating performance detection tool.

Description

technical field [0001] The invention relates to an insulation withstand voltage test device. Background technique [0002] The power frequency AC withstand voltage test is to apply a certain high voltage to the tested object and keep it for a certain period of time to verify the ability of the insulation of the tested object to withstand a certain high voltage, so as to ensure the safety of the tested object. Since the AC withstand voltage test voltage is generally higher than the operating voltage, the tested object has a large safety margin after passing the test, so the AC withstand voltage test plays a vital role in ensuring the safety of safety appliances. [0003] The AC withstand voltage test mostly uses milliampere meter readings, that is, reading the capacitive current value of the object under test, which is an important part of the test. According to the characteristics of the AC withstand voltage test, the current of the object under test is small and low when th...
