Profile:

The KDGK-MH is a comprehensive running-in test system for high-voltage circuit breakers, supporting up to 6 units simultaneously. It simulates real operating conditions (closing, opening, reclosing) to test mechanical durability and contact performance. The system features a stable high-power DC operating power supply, contact signal detection, and automatic protection against coil burnout. With intuitive parameter setting and sequence control, it is ideal for manufacturers and maintenance teams to verify breaker reliability.

Features:

  • Multi-breaker testing: Simultaneously tests up to 6 circuit breakers for efficient production validation.
  • Versatile operation modes: Supports single, combined, and reclosing operations (split, close, open, close-open, etc.).
  • Stable power supply: Custom high-power DC power supply prevents voltage drops and coil burnout.
  • Contact signal detection: Reliably identifies wiring errors and contact signal issues for troubleshooting.
  • Automatic protection: Cuts off coil power after a user-defined delay to prevent overheating during misoperation.
  • Real-time status monitoring: Displays open/closed status of all breakers for clear visibility.
  • Compliant design: Meets GB1984-2003 and DL/T846.3-2004 standards for breaker testing.
  • Easy wiring: VS1 trolley-type plug-in terminals for quick and secure connections.
  • Customizable running-in types: Pre-set and user-defined test sequences for flexible testing.
