The application discloses a kind of
direct current circuit breaker oscillation characteristic measuring device, it is related to
circuit breaker oscillation measurement technical field, including ontology, the side wall of ontology is equipped with several installation slot, and the inner wall top of installation slot is fixedly connected with upper fixed plate, the inside of upper fixed plate is equipped with inner groove, the bottom of upper fixed plate is fixedly connected with slide bar, the inner wall of inner groove is rotatably connected with
protection mechanism, to when measuring, the
cable line of winding can be protected, the outer wall of slide bar is provided with clamping mechanism, to when measuring,
cable line can be arranged.This kind of
direct current circuit breaker oscillation characteristic measuring device, by driving motor rotation runner, by resistance block and slot engagement drive winding shaft synchronous rotation, realize
cable line collection, avoid winding, improve security, after collection, driving wheel automatic stop, ensure that winding tension is in safe range, prevent cable line from being damaged, effectively protect cable line, improve use efficiency and security.
