Miniaturized multi-station operating mechanism

Abstract

The invention relates to the technical field of isolating switch equipment, in particular to a miniaturized multi-station operating mechanism, which is characterized in that a main shaft is rotatablyconnected between a bottom plate and an intermediate plate, a cam is fixedly sleeved on the main shaft, a transmission device is fixedly connected on the bottom plate and is used for driving a cam torotate along with the main shaft, and an in-place switching mechanism is fixedly connected on the intermediate plate; the in-place switching mechanism is used for cutting off a power source of the transmission device after the cam rotates in place, a manual and electric interlocking device is arranged on the intermediate plate and located on one side of the in-place switching mechanism and used for switching an electric operation mode and a manual operation mode of the transmission device, and two limiting devices are arranged on the bottom plate and symmetrically arranged on the two sides ofthe cam. The limiting devices are used for locating the rotation of the main shaft. An auxiliary switch switching device is arranged between the bottom plate and the intermediate plate and used for transmitting signals of the rotating position of the main shaft, and a pointer is arranged on the panel, is in linkage with the main shaft and is used for indicating the rotating position of the main shaft. And the moving contact can be ensured to accurately stop at each position.

Description

technical field [0001] The invention relates to the technical field of isolating switchgear, in particular to a miniaturized multi-station operating mechanism. Background technique [0002] As one of the core components in the power system, the disconnector plays the role of carrying current, and the second is to provide a clear maintenance fracture. According to the function, the isolating switch is divided into two-position isolating switch (only providing the function of isolating fracture) and three-position isolating switch (providing both functions of isolating fracture and grounding fracture at the same time). [0003] A two-position isolating switch means that it only has a closing position and an opening position; a three-position isolating switch means that it has a closing position, an isolating position and a grounding position. [0004] In the existing technology, the existing three-position isolating switch often has the situation that the movement of the movi...

Problems solved by technology

[0005] In view of this, it is necessary to provide a miniaturized multi-position operating mechanism to solve the problem that the operating mechanism cannot limit the rotation angle of the moving contact, causing the moving contact of the multi-position isolating switch to reach each position during the rotation. The problem of low location accuracy
