Embodiment Construction

[0027] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings. It should be noted that the embodiments are only specific illustrations of the present invention and should not be regarded as limiting the present invention.

[0028] As shown in the figure, the present invention discloses a three-station mechanism of a load switch integrating manual and electric functions, including a frame on which an earthing switch operating device, a main switch operating device and a three-station output device are arranged. The station output device includes a rigidly connected output bushing 1 and the first crank arm 2. The output bushing 1 is rotatably matched with the frame. One side of the first crank arm 2 is provided with a differential plate 3. On the differential plate 3 There is a first sliding groove 4, and the other side of the first crank arm 2 is provided with a first transmission pin 5, on which ...

Abstract

The invention provides a load switch three-position mechanism. The load switch three-position mechanism includes a rack; a grounding switch operation device, a closing switch operation device, and a three-position output device are arranged on the rack; the three-position output device includes an output shaft sleeve and a first crank arm which are rigidly connected; the output shaft sleeve rotatably matches the rack; a differential plate is arranged on one side of the first crank arm; a first sliding groove is formed in the differential plate; a first driving pin is arranged on the other sideof the crank arm; a first connection rod is rotatably connected to the first driving pin; when a spring energy storage device rotates over a maximum energy storage position, the stored energy is released so as to allow a main switch operation device to rotate continuously, and in this time, the main switch operation device drives the three-position output device to rotate through the first connection rod and the first driving pin so as to output a torque. The load switch three-position mechanism can achieve closing-opening-grounding three-position switching operations through two input positions and one output position, and is compact in structure and easy to use.

Description

technical field [0001] The invention relates to a three-position mechanism, in particular to a three-position operating mechanism for a load switch. Background technique [0002] The mission of the load switch is to realize the connection and disconnection of the circuit through the opening and closing action of the contact, and the opening and closing action of the contact is realized by the operating mechanism. The existing operating mechanism is complex in structure, difficult to manufacture and cumbersome to operate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a load switch three-position mechanism integrating manual and electric functions, which can realize the three-position switching of closing-opening-grounding through two input stations and one output station Operation, compact structure, easy to use. [0004] The technical scheme that the present invention solves technical problem adopts is: [0...
