The KDGK-F Circuit Breaker Dynamic Characteristic Tester is a portable, high-precision instrument for analyzing the mechanical performance of high-voltage circuit breakers. It supports 12 break ports to measure closing/opening time, bounce, speed, stroke, current, and energy storage, with a built-in adjustable DC power supply (DC20~256V/15A) for coil action voltage testing. Equipped with a large-screen LCD and Chinese interface, it features strong anti-interference capability (operable in 500kV substations), built-in printer, and data storage, making it ideal for on-site maintenance and factory quality control.
