On-Line Monitoring Device for Mechanical Properties of OLM-NZ1 Circuit Breaker
Passing the national quality inspection and verification for high voltage apparatus
The unit can be installed on various types of indoor medium voltage vacuum circuit breakers
This device is completely self-contained, and does not affect the normal operation of the original operation and control of the circuit breaker
Monitoring items: opening and closing S/T curve, over-travel, opening distance, opening/closing time, opening/closing average speed, closing speed, opening speed, and opening/closing coil current curve
Compare the S/T curve during opening/closing with the envelope of the manufactured products to determine any change in features of the circuit breaker
Reflect the running state of the circuit breaker in real-time manner
Predict the potential failure and give sound and light alarm
The mechanical characteristics of the opening and closing process are shown in real-time digital or graphical curves
Self-protection function of the circuit-breaker opening and closing coil; and real-time monitoring of coil status
Allow with standard RS485/232 communication interface, and use modbus communication protocol to realize data transfer. All the monitoring parameters can be sent to the background terminal
Automatically save the data and graphics on operating characteristics, and correspond to the operation time
