Automatic surge testing system and testing method

Abstract

The invention relates to the technical field of electronics, and particularly relates to a surge testing system. The automatic surge testing system comprises a power supply, a surge tester, a switch and a computer, wherein the power supply is used for generating power voltage; the surge tester is used for generating surge testing voltage with set magnitude; the switch is connected with the power supply, the surge tester and to-be-tested equipment for carrying out switching between a feature current testing channel and a surge impact channel under effects of control signals; and the computer is connected with the power supply and the surge tester for communication, testing information of the to-be-tested equipment is acquired, and the computer is also connected with the switch for generating control signals. The testing system of the invention is simple and effective, the operation is convenient, surge voltage can be automatically tested and judged, and manual workload is greatly reduced.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a surge test system. Background technique [0002] Surge voltage is a key performance indicator to characterize the performance of a device or equipment. It is a must-test item in many test applications. In the traditional surge test, a switch is connected in series at the voltage output end of the surge generator, and it is turned on when the switch is open. The voltage output terminal of the surge generator raises the surge test voltage to the specified voltage level, and then closes the switch to apply the surge test voltage to the device under test. After the surge impact, the tested Disconnect the device from the surge generator, then connect it to the power supply, test the relevant characteristic current parameters, and decide whether to repeat the above steps according to the value of the characteristic current parameters, and finally obtain the maximum surge voltage;...
