Switching power supply high-voltage test system

Abstract

The invention provides a switching power supply high-voltage test system comprising a high-voltage tester which is used for outputting a high voltage required by a test, judging whether the insulationperformance among an AC-DC terminal, an AC-FG terminal and a DC-FG terminal of a tested switching power supply reaches the standard or not, and outputting a judgment result. The automatic switching device is used for automatically carrying out test item wiring conversion according to a set sequence and indicating a test result; the test frame is used for supporting the tested switching power supply and electrically connecting alternating current, direct current and shell grounding terminals of the tested switching power supply with AC, DC and FG wiring terminals of the automatic switching device; the automatic switching device comprises a circuit device; the circuit device comprises a high-voltage wiring terminal H1, a low-voltage wiring terminal L1 and an RS232 interface which are used for being electrically connected with the high-voltage tester, and an automatic switching module which is used for achieving automatic switching of wiring of a test project. In the using process, frequent manual wiring switching is not needed, operation is convenient and safe, and the working efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the field of switching power supply high-voltage testing, in particular to a switching power supply high-voltage testing system. Background technique [0002] Before the switching power supply leaves the factory, a high voltage test is required to determine whether the insulation performance of the corresponding parts or components is up to standard. The switching power supply high voltage test generally needs to test three items: first, the AC input terminal AC of the switching power supply is to the output terminal DC of the switching power supply; second, the AC input terminal AC of the switching power supply is to the shell ground FG of the switching power supply; third, The output terminal DC of the switching power supply is connected to the shell ground FG of the switching power supply. At present, the common practice of high-voltage testing of switching power supplies is: manually connect the output terminals H and L of...

AI Technical Summary

Problems solved by technology

The current practice of high-voltage testing of this type of switching power supply has the following problems: each switching power supply needs to be manually connected and disconnected three times, two circuits each time, the operation is cumbersome, the operation error rate is high, and the production efficiency is low. And there are security risks
