OM.R960 Circuit Breaker Mechanical Characteristics Online Monitoring System

Product Overview
The OM.R960 circuit breaker mechanical characteristic online monitoring system employs advanced communication, microprocessor, sensing, and database management technologies to perform real-time, online monitoring of high-voltage circuit breakers during operation. Key parameters monitored include the main circuit current, breaker opening/closing status, spring energy-storage motor current, opening/closing coil current, contact travel—essentially all fundamental characteristics of the circuit breaker mechanism. By analyzing this data, the system can calculate parameters such as opening/closing speed and operating time, enabling an assessment of the high-voltage circuit breaker's operational condition. Additionally, it provides functionalities like current waveform analysis, evaluation of contact wear, and estimation of remaining electrical life.

Advantageous Features
● Record and analyze curves such as operating current, on/off coil current waveforms, stroke characteristic waveforms, velocity profile waveforms, breaking current waveforms, auxiliary switch waveforms, and virtual break point waveforms.
● By conducting a comprehensive comparative analysis of the curves (time-displacement curve, operating coil current curve), combined with the factory-standard curves, we can assess changes in mechanical condition and identify emerging trends (such as displacement status, time progression, velocity variations, failure-to-operate events, and unintended tripping).
● Satisfy the access switch characteristic auxiliary node signal
● The travel sensor features a robust, safety-locking bearing design, with multiple principles available for selection (such as attitude sensors, magnetic offset sensors, laser sensors, etc.)
