Title:
遮断器用ばね操作機構の状態監視システム、および遮断器用ばね操作機構の監視方法
Document Type and Number:
Japanese Patent JP7467781
Kind Code:
B2
Abstract:
This status-monitoring system for a circuit breaker spring-operating mechanism of an embodiment comprises a one-dimensional equivalent circuit network-calculating unit, a status-determining unit, and an abnormal-location-specifying unit. The one-dimensional equivalent circuit network-calculating unit calculates calculated value data representing the state of the spring-operating mechanism by applying measured value data to a one-dimensional equivalent network model. The status-determining unit determines whether the state of any component of the spring-operating mechanism is abnormal on the basis of the comparison result between the measured value data and normal calculated value data calculated with a normal state parameter by the one-dimensional equivalent circuit network-calculating unit. The abnormal-location-specifying unit changes the parameter so that the difference between the measured value data and the calculated value data is within a preset range, and when the parameter is changed, specifies the component associated with the parameter that differs from the normal state parameter by more than the standard as being an abnormal location.
