Embodiment 1

[0035] An operating mechanism shared by opening and closing, the operating mechanism includes a guide shaft 15, a slider 1 slidably connected to the guide shaft 15, an opening half shaft 3 arranged under the rear end of the slider 1, and an opening half shaft 3 arranged on the slider 1. The closing half shaft 2 below the front end, the front and rear parts of the bottom surface of the slider 1 are provided with hooks 12, when the slider 1 moves forward along the guide shaft 15, the hooks 12 at the front of the slider 1 hook The closing semi-axis 2, and then the slider 1 rotates with the guide shaft 15 as the axis, driving the closing semi-axis 2 to rotate to realize the closing; when the slider 1 moves backward along the guide shaft 15, the rear of the slider 1 The hook 12 on the top hooks the opening semi-shaft 3, and then the slider 1 rotates with the guide shaft 15 as the axis, driving the opening semi-axis 3 to rotate to realize the opening, and the structure of the operati...

Abstract

The invention relates to an operating mechanism for switching, and a frame circuit breaker. The operating mechanism comprises a guide shaft, a sliding block which is slidingly connected to the guide shaft, a switching-off half shaft disposed below the rear end of the sliding block, and a switching-on half shaft disposed below the front end of the sliding block. The front part and the rear part of the bottom surface of the sliding block are provided with clamping hooks. The frame circuit breaker is provided with the operating mechanism for switching, a push-pull unit which is used for controlling the sliding block in the operating mechanism to move back and forth, and a tripper which is used for controlling the sliding block in the operating mechanism to rotate around the guide shaft, wherein the tripper is located above a press part of the sliding block, and moves downwards in the vertical direction. Compared with the prior art, the operating mechanism can performance the switching operation through one tripper. Compared with a conventional frame circuit breaker, the circuit breaker employs one fewer trippers, thereby reducing the size of the circuit breaker and saving the total cost.

Description

technical field [0001] The invention relates to a frame circuit breaker, in particular to an operating mechanism for opening and closing of the frame circuit breaker. Background technique [0002] The frame circuit breaker is also called a universal circuit breaker, which is a kind of current that can be connected, carried and broken under normal circuit conditions, and can also be connected, carried for a certain period of time and broken under specified abnormal circuit conditions. Mechanical switching electrical appliances, the circuit breaker has a variety of intelligent protection functions, which can achieve selective protection, precise action, avoid unnecessary power outages, and improve power supply reliability. At present, all products in the industry use two releases for automatic opening and closing operations, that is, a shunt release is used for opening, and a closing electromagnet is used for closing, so as to realize the closing and opening of the frame circu...
