Profile:

The KDGK-HL is a comprehensive 2-in-1 tester for high-voltage circuit breakers, combining mechanical characteristic analysis and loop resistance measurement. It supports testing of 12 breakpoints, measuring time, speed, stroke, bounce, and current waveforms, while also performing 100A loop resistance tests with 0.01μΩ resolution. The device features a large touchscreen, built-in printer, and data storage for field tests, with strong anti-interference capabilities suitable for live substation environments. Its compact, portable design makes it ideal for on-site commissioning and maintenance of circuit breakers.

Features:

  • 2-in-1 design: Combines mechanical characteristic testing and loop resistance measurement.
  • 12-breakpoint testing: Measures closing/opening time, speed, stroke, bounce, and current waveforms.
  • High-precision loop resistance test: 100A test current with 0.01μΩ resolution.
  • Built-in adjustable DC power supply: 0~270V/20A for circuit breaker low-voltage action testing.
  • Strong anti-interference: Performs reliable tests even in 500kV live substations.
  • Intuitive touchscreen interface: 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 case: Designed for field use in harsh substation environments.
