Abstract

The invention relates to an electric quantity monitoring accessory for a direct-current molded case circuit breaker, and belongs to the technical field of ship low-voltage direct-current power. The electric quantity monitoring accessory comprises a shell base, an embedded fixing piece, a PCB A, a PCB B and a shell cover. The shell base is connected with the shell cover, and the embedded fixing piece, the PCB A and the PCB B are arranged on the shell base between the shell base and the shell cover. The PCB A is connected with the PCB B. The electric quantity monitoring accessory is embedded ina base of a direct-current molded case circuit breaker, and the functions of collecting and uploading electrical parameters such as line voltage, current, power and the on-off state of the circuit breaker are achieved in a ship environment. The accessory adopts a separated design, so that a user can maintain and replace the electric quantity accessory conveniently. In terms of boundary dimension,the size of an electrical parameter monitoring unit and the number of modules in a distribution board are reduced, internal connection circuits are simplified, and miniaturization of the distributionboard is facilitated.

Description

technical field [0001] The invention relates to a power consumption monitoring accessory of a DC molded case circuit breaker, which belongs to the technical field of low-voltage DC power for ships. Background technique [0002] With the continuous improvement of the level of intelligent manufacturing in the shipbuilding field, new requirements are put forward for the functions of molded case circuit breakers. In addition to the traditional overload, inrush and other protections, it is also required to detect the electrical parameters such as voltage and current of the circuit where the circuit breaker is located. function, and at the same time realize the monitoring of the opening and closing status of the circuit breaker and upload all the monitoring data to the host computer to realize communication monitoring, which is convenient for users to inspect the line status. The electrical parameter monitoring technology of the traditional DC power distribution system mainly uses...
