PURPOSE: Power substation equipment with vibration-sensing and shutting-off functions is provided to prevent safety accidents beforehand by selectively cutting a molded-case circuit breaker at a dangerous area. CONSTITUTION: A main body of power substation equipment comprises a molded-case circuit breaker. A vibration sensor senses vibration. A safety controller(30) selectively cuts off the molded-case circuit breaker. A display panel(40) displays a vibration graph of the vibration sensor in real-time. A microphone(50) detects internal noise. [Reference numerals] (15c) Circuit breaker; (20) Vibration sensor; (30) Safety controller; (40) Display device; (50) Microphone |
