Abstract

The invention relates to a mechanical property state monitor of a circuit breaker, consisting of two current sensors, a voltage divider, a data acquisition unit and a computer. One current sensor is arranged on a current loop of a breaking-closing coil of the circuit breaker and the other current sensor is arranged on a current loop of an energy storage motor of the circuit breaker; one side of the voltage divider is connected with a battery loop and the other side of the voltage divider is connected with the data acquisition unit; analog signals of the current sensors and the voltage divider are changed into digital signals and digital data is transmitted to the computer by a signal acquisition unit; acquiring analysis identification software in the computer controls the data acquisition unit to acquire and stores data, analyzes and judges the sampled data to obtain a judge result, displays and manages data. The invention has the advantages of simple operation, reliable running, high intellectualization and networking.

Description
