Profile:

The KDGK-SHL is a comprehensive high-voltage circuit breaker tester combining mechanical characteristic analysis and 3×100A loop resistance measurement. It supports 12 breakpoints, measuring time, speed, stroke, bounce, and current waveforms, while simultaneously testing three-phase main contact resistance. The device features a touchscreen interface, built-in printer, and data storage, with strong anti-interference capabilities for live substation testing. Its compact design and adjustable DC power supply make it ideal for on-site commissioning and maintenance of all types of circuit breakers.

Features:

2-in-1 integration: Mechanical characteristic testing + 3×100A loop resistance measurement.
12-breakpoint analysis: Measures closing/opening time, speed, stroke, bounce, and current waveforms.
Three-phase resistance test: Simultaneously measures main contact resistance on all three phases.
Adjustable DC power supply: 0~270V/20A for low-voltage operation testing of circuit breakers.
Strong anti-interference: Reliable testing in 500kV live substation environments.
Intuitive touchscreen: Chinese menu for easy operation and data visualization.
Built-in thermal printer: Generates on-site test reports for immediate documentation.
Data storage & PC analysis: Stores test data and supports PC software for advanced analysis.
Customizable speed analysis: Allows arbitrary analysis of closing/opening speed curves.
Rugged portable design: Suitable for field use in harsh substation conditions.
