Embodiment

[0018] Such as figure 1 As shown, a specimen failure discrimination system for lightning surge test, including lightning surge test device 1, pulse peak detection device 2, control unit 3 and host computer 4, pulse peak detection device 2 connected to lightning surge test The device 1 and the control unit 3 are connected to the pulse peak detection device 2 and the lightning surge test device 1 through a bus, and the host computer 4 is connected to the control unit 3 . The upper computer 4 is used for remote control, and connects multiple user computers 5 through a local area network, so that testers can query test reports at the same time.

[0019] The specific process of a test piece failure discrimination method using the above-mentioned system is as follows: figure 2 shown, including the following steps:

[0020] 1) Set the over-limit voltage of the lightning surge test, and start the lightning surge test device to perform the lightning surge test on the test piece;

Abstract

The invention relates to a test piece failure distinguishing system and a test piece failure distinguishing method for a lightning surge test. The test piece failure distinguishing system comprises a lightning surge testing device, a pulse peak detecting device, a control unit and an upper computer; the pulse peak detecting device is connected with the lightning surge testing device; the control unit is connected with the pulse peak detecting device and the lightning surge testing device through buses; the upper computer is connected with the control unit; when the lightning surge test is performed, the pulse peak detecting device is started by the control unit to detect peak current and peak voltage which are born by a test piece; the control unit acquires the detected peak current and the detected peak voltage from the pulse peak detecting device, transmits the peak current and the peak voltage to the upper computer, judges the peak current and the peak voltage, controls the lightning surge testing device to stop the test and simultaneously gives an alarm if the peak current is higher than threshold current; and the upper computer automatically generates a test report according to the peak current and the peak voltage. Compared with the prior art, the test piece failure distinguishing system and the test piece failure distinguishing method for the lightning surge test have the advantages that whether the test piece fails or not can be quickly distinguished, and practicality is high.

Description

technical field [0001] The invention relates to a lightning strike surge test system and method, in particular to a test piece failure discrimination system and method for lightning strike surge test. Background technique [0002] At present, when the specimen is tested for lightning strike and surge, due to the lack of specific detection equipment and alarm mechanism. After each set of experiments, testers need to do another test to determine whether the test piece is damaged or invalid, which consumes a lot of time and manpower, and often cannot judge the performance of the tested item in a timely and effective manner, which may easily cause damage to the test piece . Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a highly practical test piece failure judgment system and method for lightning surge tests, which can quickly judge whether the test piece fails. [0004] The pur...
