Switch characteristic tester speed at the moment of contact separation or contact
Switch characteristic tester, full name high-voltage switch mechanical characteristic tester, is a "physical examination doctor" specially used to detect and diagnose the mechanical performance of high-voltage circuit breakers (such as vacuum switches, SF6 switches, oil switches).
High-voltage circuit breakers undertake the dual tasks of control and protection in the power system. Their speed of operation, synchronization, and good contact of contacts directly affect the safety of the power grid. The switch characteristic tester captures dynamic parameters such as time, speed, stroke, and current at the moment of opening and closing of the switch to determine whether its mechanical mechanism is healthy.
