Problems solved by technology

[0002] The main function of the operating mechanism of the direct-acting three-position isolating switch is to transmit the rotational motion of the drive motor to the rotating shaft of the three-position isolating switch through a series of transmission components; the existing technology is to use gear transmission in the transmission structure. Movement, the operating mechanism has a large volume, a large number of parts, and a complex structure, which is not conducive to reducing the overall weight of the equipment. At the same time, because all transmissions use gears, the cost of the entire operating mechanism is also relatively high.

Abstract

The invention discloses an operating mechanism of a direct-acting three-position isolation switch. The operating mechanism comprises a driving shaft A, a driving shaft B and a driving shaft C which are arranged in parallel; a chain wheel A, a chain wheel B and a chain wheel C are arranged on the driving shaft A, the driving shaft B and the driving shaft C respectively; and the driving shaft A, the driving shaft B and the driving shaft C are linked with one another through transmission chains. The operating mechanism is characterized by further comprising a driving motor; and a transmission gear set is arranged between an output shaft and a driving shaft C of the driving motor. By the scheme of the invention, transmission parts are reduced; the cost is reduced, the structure is simple, the weight is light; and the three-position switch is safely protected.

Description

technical field [0001] The invention relates to a direct-acting three-position isolating switch, in particular to an operating mechanism of a direct-acting three-position isolating switch, belonging to the technical field of isolating switches.
