摘要： A sensing apparatus and a sensing method are provided. The sensing apparatus (100) comprises a current sensing circuit (104) configured to sense a secondary current generated from a current transformer (102) to generate a secondary current signal representing the secondary current, the current transformer (102) being configured to receive a primary current from a bus bar to generate the secondary current for supplying a power to the sensing apparatus (100); and a controller (106) configured to detect a peak value of the secondary current signal during a saturation of the current transformer (102), and configured to measure the primary current based on the peak value of the secondary current signal by a look-up table.

摘要： Embodiments of the present disclosure relate to a method for managing a breaker and a controller of a breaker. In the method, at least one test time interval is obtained, the at least one test time interval is between at least one actuation point and at least one change point for at least one test current that is caused by applying at least one test voltage to a coil of the breaker. A change point is detected for an actual current that is caused by applying an actual voltage to the coil. An actuation point is determined for the actual current at least based on the change point for the actual current and the at least one test time interval. With these embodiments, the actuation point may be determined in a simple way without a need of a voltage sensor being deployed in the breaker.

摘要： A pivot supporting structure for a circuit breaker and a circuit breaker. The pivot supporting structure comprises: a supporting body having a supporting hole for receiving and pivotally supporting a pivot pin connected to an actuating mechanism of the circuit breaker, wherein at least one strain gauge are mounted to the supporting body for sensing the force acting on the pivot supporting structure by the actuating mechanism. This pivot supporting structure can accurately sense the characteristic force applied, such that the contact force and mechanical characteristics of the circuit breaker can be on-line monitored.

摘要： Embodiments of the present disclosure provide a method for monitoring a circuit breaker, comprising the following steps: obtaining a characteristic force associated with an actuating mechanism of the circuit breaker over the time; and determining the time point when the closing and/or opening of the circuit breaker occurs by identifying a variation of the force. The step of determining further comprises determining the moment when a variation increase of the characteristic force occurs as the time point of the closing of the circuit breaker; and determining the moment when a variation decrease of the characteristic force occurs as the time point of the opening of the circuit breaker. The method can be used to accurately on-line monitor the closing and opening time point of the circuit breaker.
