The power monitoring accessory comprises a housing, the housing is provided with a cover plate, a circuit board is arranged at the internal portion of the housing and the cover plate, a circular through hole is reserved at the front surface of the housing, the outer side of the circular through hole is provided with a current transformer, and the housing is provided with a connector; and the connector and the current transformer are connected with the circuit board. The power monitoring accessory for the AC moulded case circuit breaker can solve the problem of the power parameter monitoring function of the moulded case circuit breaker, and is convenient to install and easy to dismount.

Description

technical field [0001] The invention relates to a power monitoring accessory for an AC molded case circuit breaker and a using method thereof, belonging to the field of low-voltage electrical appliances. Background technique [0002] With the development of intelligent ships and the continuous improvement of the level of electrical intelligence of ships, a remote monitoring function has been proposed for molded case circuit breakers, which is used to monitor parameters such as voltage, current, and power of circuit breakers. [0003] At present, the monitoring of electrical parameters of power distribution equipment mainly adopts the conventional sensor + data acquisition unit (such as PLC) and other methods. In this way, the monitoring unit is placed outside the circuit breaker, usually installed in the Internally, due to the large volume of the sensor and the acquisition unit, this increases the volume of the power distribution equipment. There are also some applications ...
