Scope: The standard stipulates the testing methods for the performance parameters of vacuum switch tubes for contactors, and specifies the requirements for test equipment and test conditions and the general rules that should be followed. This standard applies to vacuum switch tubes for AC vacuum contactors with AC 50 or 60Hz and rated voltage 10kV and below. When quoting this standard to formulate detailed specifications, the scope and provisions of the citation should be specified and specified. If there are no test conditions and test methods specified in this standard, and it is necessary to test certain performance parameters of some switching tubes, they should be separately specified in the detailed specifications. If it is verified that the rapid test method or other equivalent test method is equivalent to the method specified in this standard and is approved by the relevant department, it can be considered valid.
