Test methods and test system of flood-voltage performance of the bimetallic waterproof thermostat

摘要

[object of the present invention is to provide a test method and a test system of flood-voltage performance of the bimetallic waterproof thermostat. A The test method includes the following steps. A. The thermostat body is immersed in a first metal container water is contained, to the metal terminal portion of the thermostat conductors are immersed in a second metal container which water is contained. B. the ground clip to connect to the breakdown voltage tester is brought into contact with the first metal container, contacting the test bar of the test probe to be connected to the breakdown voltage tester to the second metal container. Upon detecting the flush phenomena in the thermostat body of C. said first metal container, thermostat body for immersion in said first metallic container is determined to be defective. Using the test method, the test operation of the thermostat, when leaving the defective thermostat, the phenomenon of remarkable flashover or flash in a metal container which water is accommodated appeared, thereby quickly detect the failure of the thermostat. .FIELD 1
