circuit breaker are monitored by the displacement sensor and hall element. Based

on Eaton's R&D, manufacturing, and application experience, the professional

diagnostic algorithm is used to monitor the changing trends of the switch

characteristic state, judge and predict the operation of circuit breaker, and realize

the transition from planned maintenance to condition-based maintenance of the

circuit breaker, realizing timely detection and early treatment of circuit breaker

faults and further ensuring the safe and reliable operation of the distribution

system.

sensors, and the mechanical characteristic parameters of the circuit breaker can be

obtained by intelligent model analysis and calculation.

breaker, comprehensively judge the load and temperature rise of switchgear, give

early warnings and alarms for the state of the circuit breaker and switch, and

provide diagnosis opinions and suggestions.

• Evaluates the state of circuit breaker mechanism, electric chassis, electric

grounding switch, and other equipment and informs users, gives alarm and early

warning to mechanism and electrical faults, and provides self-diagnosis opinions of

the faults;

a comprehensive analysis and judgment, gives early warning information on

excessive temperature rises or bad rises, and provides reasonable solutions;

• Based on the mechanical characteristics, action current, and action time of the

circuit breaker mechanism, the system analyzes the mechanism characteristics,

finds fault symptoms such as refusing action and mis-operation in advance, makes

mechanical life judgments, sends out early warning information in time, and

generates operation and maintenance reports, which can save circuit breaker

maintenance costs, reduce equipment/system losses, avoid major accidents, and

effectively improve the operation reliability of the system.
