    HV switch mechanical properties tester

    It is used to mechanical properties test for imported or domestic less-oil, more-oil, SF6, vacuum switch, etc. The time parameters of Max 12 channels can be recorded simultaneously and S-t、V-s、I-t character curve can be presented. It records the total and instantaneous action of switch contactor. It is very useful to analyze the switch potential fault during producing and operation. Moreover, the speed and over-travel parameters can be set according to different switch, which can ensure all of curves are the actual speed character of switch.
