Brief: We show the practical steps and results so you can judge suitability quickly. This video demonstrates the ZXMN-A Portable Protection Relay Circuit Breaker Analyzer Simulator in action, showcasing how it simulates circuit breaker tripping and closing operations for relay protective device testing. You'll see its touch keyboard operation, voice prompts, and how it helps extend circuit breaker service life and improve testing efficiency without powering off devices.
Related Product Features:
  • Simulates circuit breaker tripping and closing to reduce switch on/off actions and extend service life.
  • Features touch keyboard operation with pilot lamp indication and voice prompts for user guidance.
  • Utilizes a Single Chip Microcomputer as the core of the control circuit for reliable performance.
  • Low voltage control circuit is made of integrated circuit for enhanced safety and efficiency.
  • Employs photocoupling and solid state components to ensure stable and accurate control.
  • Input circuit is isolated from the strong current part, withstanding up to 220KV AC/DC voltage.
  • Offers multiple tripping and closing time choices with minimal error for precise testing.
  • Portable design with compact dimensions and lightweight for easy transport and use.
FAQs:
  • What is the primary function of the ZXMN-A Circuit Breaker Simulator?
    The ZXMN-A is designed for relay protective device total group testing, simulating circuit breaker tripping and closing to reduce switch on/off actions, extend circuit breaker service life, and improve working efficiency without powering off the tested devices.
  • What are the available tripping and closing current options?
    The simulator offers multiple current choices including 0A, 0.25A, 0.5A, 1A, 2A, 4A, and 5A, allowing for flexible testing scenarios.
  • How accurate is the tripping and closing time simulation?
    The device ensures high precision with a single contact tripping/closing time error of +1ms and a total contact group error of ±2ms.
  • What input voltage does the ZXMN-A simulator require?
    It operates on an input voltage of AC220±10%, making it suitable for standard power environments.
