Abstract

The invention discloses a three-station operating mechanism which comprises a base, a panel, an isolation operating shaft, a grounding operating shaft, a linkage assembly and an operating handle. An isolation shaft sleeve is concentrically fixed at the front end of the isolation operation shaft, a grounding shaft sleeve is concentrically fixed at the front end of the grounding operation shaft, an isolation operation hole aligned at the isolation shaft sleeve and a grounding operation hole aligned at the grounding shaft sleeve are formed in the panel, and an isolation opening is formed in the isolation shaft sleeve. The grounding shaft sleeve is provided with a grounding opening, and the operating handle is provided with a protruding block. An isolation opening gap and an isolation closing gap are further formed in the peripheral side of the isolation operation hole, a grounding opening gap and a grounding closing gap are further formed in the peripheral side of the grounding operation hole, and a limiting block is further arranged on the protruding block in a protruding manner. The three-station operating mechanism has the advantages of simple structure, compact arrangement, reliable interlocking, safety and stability.

Description

technical field [0001] The present application relates to the field of electric equipment, in particular to an operating mechanism. Background technique [0002] With the development of information technology and the miniaturization and intelligent requirements of the power sector for power equipment, the power sector has higher and higher requirements for the space occupied by power equipment and intelligence, strong performance, small size, long life, easy to use, and reliable operation , versatility, and low cost have become the design goals. For this reason, with the development of gas-insulated metal-enclosed switchgear in recent years, the three-position isolating-grounding combination switch is characterized by its small size, compact structure, flexible and diverse configuration methods, and it can also realize the interlocking of the isolating switch and the grounding switch. More and more manufacturers are using it. [0003] The three-position isolating switch is...
