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.

Technical field
The present invention relates to a kind of lightning surge test pilot system and method, especially relate to a kind of test specimen inefficacy judgement system and method that is used for the lightning surge test.
Background technology
At present, test specimen is when doing the lightning surge test, owing to lack specific checkout equipment and alarm mechanism.Whenever need the tester to do test in addition to have judged whether test specimen has damaged inefficacy, has expended great amount of time and manpower after doing one group of experiment, and often can not judge timely and effectively, cause the damage of test specimen easily by the performance quality of examination article.
Summary of the invention
The object of the invention is exactly to provide a kind of can differentiate test specimen fast and whether lost efficacy practical the test specimen inefficacy judgement system and the method that are used for the lightning surge test in order to overcome the defective that above-mentioned prior art exists.
The object of the invention can be realized through following technical scheme:
A kind of test specimen inefficacy judgement system that is used for the lightning surge test; Comprise lightning surge test unit, peak value of pulse pick-up unit, control module and host computer; Described peak value of pulse pick-up unit connects the lightning surge test unit; Described control module connects peak value of pulse pick-up unit and lightning surge test unit through bus, and described host computer connects control module;
When the lightning surge test unit carried out the lightning surge test to test specimen, control module starting impulse peak detector detected peak point current and the PV that test specimen bore; Control module obtains detected peak point current and PV by the peak value of pulse pick-up unit, sends it to host computer, and judges, if peak point current is higher than the preset threshold value electric current, then controls the lightning surge test unit and stops test, gives the alarm simultaneously; Host computer generates test report automatically according to the peak point current and the PV that receive.
Described host computer is used to realize Long-distance Control, and this host computer is connected with at least one subscriber computer through network.
A kind of test specimen inefficacy method of discrimination of using said system may further comprise the steps:
1) voltage that transfinites that lightning surge is tested is set, and startup lightning surge test unit carries out the lightning surge test to test specimen;
