Isolating switch mechanism

Abstract

The invention discloses an isolating switch mechanism which comprises a bearing seat and a moving contact. A guide driving mechanism is arranged on the bearing seat, one end of the guide driving mechanism is connected with the bearing seat, the other end of the guide driving mechanism is connected with the moving contact, and the guide driving mechanism can drive the moving contact to rotate in a reciprocating manner by taking the length of the guide driving mechanism as the radius so as to form a contact opening and closing area. According to the invention, through the guiding driving mechanism and an opening and closing guiding mechanism, during the process that the moving contact can rotate to carry out a closing action, the moving contact is guided to be aligned at a contact piece group and to limit the position of the rotating moving contact in real time, during the specific implementation, the moving contact can be driven by the guide driving mechanism to circumferentially move in the contact opening and closing area so as to perform the closing action, and in the process, the guide driving mechanism guides the moving contact to be aligned at the contact piece group, and the position of the moving contact moving in the circumferential direction is limited through the opening and closing guide mechanism so as to implement the real-time position limiting action.

Description

technical field [0001] The invention relates to the technical field of isolating switches, in particular to an isolating switch mechanism. Background technique [0002] The isolating switch, also known as the knife switch, is a low-voltage electrical appliance that can be powered off and on. The moving contact is driven by the linkage mechanism to move between the contact pieces to complete the opening, closing and grounding actions; when the equipment is overhauled, the isolating switch is used to isolate the electrified and non-energized parts, resulting in an obvious disconnection point and repairing The equipment is isolated from the power system to ensure the safety of staff and equipment. [0003] In the prior art, such as the patent document with the patent application number CN202021371452.8, it discloses an isolating switch mechanism and an isolating switch, which controls the stop position of the limit cam at the left and right positions through the limit dial , ...
