Description

Technical Field

[0001] The utility model relates to the technical field of intelligent circuit breaker equipment, in particular to a modular assembly structure of a multi-pole intelligent circuit breaker. Background Art

[0002] The intelligent circuit breaker mechanism is located on the front of the circuit breaker. The mechanism adopts a five-link free release mechanism and is designed in an energy storage form. During the use of the intelligent circuit breaker, the mechanism is always in the pre-energy storage position. As long as the circuit breaker receives a closing command, the circuit breaker can be closed instantly. The release of the pre-stored energy is completed by a button or a closing electromagnet. The electric transmission mechanism is self-contained, and the energy storage shaft and the main shaft are movably connected through a concave and convex wedge, which is easy to assemble and disassemble.

[0003] Patent No. CN217983225U The utility model discloses a modular intelligent circuit breaker installation structure, which specifically relates to the field of circuit breaker installation structure, including a body. The utility model is provided with a card slot, a buffer pad, a card block, a slider, a slide plate, a pull plate, and a first spring, which is conducive to the use of the inner wall of the card slot opened on one side of the body and the card block fixedly connected to one side of the buffer pad for card connection, so that one side of the buffer pad is tightly connected to one side of the body, and the outer wall of the slider driven by the pull plate is slidably connected to the inner wall of the slide plate embedded in the top of the body, and at the same time, the first spring fixedly connected to one side of the pull plate is contracted. When the slide plate slides on the top of the body, the two second springs fixedly connected to one side of the slide plate are contracted, and the screw rod, the threaded hole plate, and the ring are installed, which is conducive to the use of the outer wall of the screw rod and the inner wall of the threaded hole plate connected through one side of the slide plate for threaded connection until the outer wall of the screw rod is tightly connected to the external wall.

[0004] However, there are some problems in the use of existing trough bus ducts. At present, due to the needs of monitoring and control functions, intelligent circuit breakers have many more cables for signal transmission than traditional single-function circuit breakers. Therefore, the wiring is very complicated, especially for products with zero-sequence mutual inductance instruments. One pole mechanism must be assembled before the second pole can be assembled, which has low assembly efficiency and inconvenient product maintenance. Utility Model Content
