Abstract:

Short-time withstand current test and peak withstand current test is an important test to check the electrical performance.With the increasing capacity of short circuit test system of low voltage apparatus,some tests of high voltage apparatus can be carried out.In this paper,the short-time withstand current test and peak withstand current test of high voltage apparatus based on the short circuit test system of low voltage apparatus is taken as the research object,and the calculation and test methods are proposed from the perspective of current debugging,including setting current effective value and current peak value.The method can be applied to the short-time withstand current test and peak withstand current test of high voltage apparatus in the short circuit test system of low voltage apparatus,and provide reference for personnel.

Key words: low voltage apparatus short circuit test system, high voltage apparatus, short-time withstand current test and peak withstand current test, current debugging
