The KDGK-HA Circuit Breaker Dynamic Characteristic Tester is a professional instrument for analyzing the mechanical performance of high-voltage circuit breakers. It features an 8.4-inch high-brightness color touchscreen with a Windows operating interface, supporting 12-channel measurement of opening/closing time, bounce, speed, stroke, and current. Equipped with a built-in adjustable DC power supply (DC30~265V/30A), high-speed thermal printer, and U disk interface, it enables efficient on-site testing and data analysis. With strong anti-interference capability (suitable for 800kV substations), it is ideal for factory quality control and substation maintenance.
