Embodiment Construction

[0025] see figure 1 , the shape of the present invention follows the shape of the existing low-voltage one-pole (1P) miniature circuit breaker. The base and the upper cover are assembled into one body through rivets, and are embedded in the guide rail in a manner consistent with the national standard GB10963, and are fixed to the guide rail by the elasticity of the clamping plate. It is fully compatible with the shape and installation method of the existing low-voltage one-pole (1P) miniature circuit breaker.

[0026] see figure 2 , image 3 , an intelligent magnetically latched miniature circuit breaker, including a housing, a magnetically latched relay, and a drive circuit, and the drive circuit drives the magnetically latched relay to act after receiving a control signal; the magnetically latched relay includes a moving spring combination 2, a static spring combination 1, and a lever 4 , push piece 3, magnetic steel combination 6, iron core 8 with coil, yoke iron combin...

Abstract

The invention discloses an intelligent magnetic latching miniature circuit breaker, which comprises a shell, a magnetic latching relay and a driving circuit, wherein the driving circuit receives a control signal and then drives the magnetic latching relay to work; the magnetic latching relay comprises a movable spring assembly, a stationary spring assembly, a stirring rod, a pushing sheet and a magnetic steel assembly; the intelligent magnetic latching miniature circuit breaker also comprises a central processing unit, a communication chip and a measurement module; and the measurement module is used for measuring power, voltage and current data and sending the data to the central processing unit. The intelligent magnetic latching miniature circuit breaker has the advantages that: the conventional design idea for a miniature circuit breaker is eliminated; and by arranging the magnetic latching relay, the central processing unit, a current transformer, a measurement chip and the communication chip in a shell of the miniature circuit breaker, the miniature circuit breaker has protection, measurement, control and communication functions.

Description

technical field [0001] The invention belongs to a circuit breaker device, in particular to an intelligent magnetic holding miniature circuit breaker in the field of small circuit breaker devices. Background technique [0002] The miniature circuit breaker is the most widely used terminal protection device in the building electrical terminal power distribution device. The miniature circuit breaker is just a mechanical switching device, the function of the device is limited, and the normal operation can only be manual. It cannot meet the requirements of increasing informatization, networking, intelligence and multi-function of power distribution system. It is the general trend to develop a multi-functional intelligent miniature circuit breaker, and it is also the development direction of miniature circuit breakers. [0003] The magnetic latching relay is a new type of relay developed in recent years, and it is also an automatic switch. Magnetic latching relays were originall...
