Embodiment Construction

[0026] Embodiment 1 of the switchgear spring operating mechanism, such as Figure 1-11 As shown, it includes housing, energy storage part, input cam 1, output cam 2, energy storage transmission mechanism and opening and closing transmission mechanism.

[0027] The housing includes a bottom plate 3 and a cover plate 4 . The bottom plate 3 is in the shape of a knife handle with a bent portion at the front end and a shank at the rear end and is provided with a guide hole extending along the front and rear directions thereof. The cover plate 4 has the same shape as the bottom plate 3 and passes above the upper surface of the bottom plate 3. The side plates standing on the left and right sides of the base plate 3 are fixed on the base plate 3, so that the base plate 3 and the cover plate 4 form a box body; the cover plate 4 is provided with a guide hole 4-1 corresponding to the guide hole on the base plate 3 .

[0028] The energy storage part includes a closing spring 5, an openi...

Abstract

The invention relates to a spring operating mechanism for a switch cabinet, which comprises a shell, an energy storage part, an input cam, an output cam, an energy storage transmission mechanism and an opening / closing transmission mechanism, wherein the energy storage part comprises opening and closing springs, a spring stretching seat, a driving disk device and a spacing disk; the spring stretching seat is flexibly assembled on the shell in the front-back direction of the shell; the driving disk device is rotatablely assembled in the shell; the spacing tray is used for connecting with an operating shaft of a corresponding switch in a transmission mode; the driving disk device and the spring stretching seat are connected through a link assembly and form a crank-slider mechanism; the back ends of the opening and closing springs are respectively suspended on the spring stretching seat; the front end of the opening spring is suspended on the front end of the shell; and the front end of the closing spring is suspended on the spacing disk. The opening and closing springs store energy simultaneously, thereby eliminating the hidden danger of incapability of opening in the opening spring of the existing spring operating mechanism since the energy needs to be supplied by the closing spring.

Description

technical field [0001] The invention relates to an accessory for a switch cabinet, in particular to a spring operating mechanism for a switch cabinet. Background technique [0002] At present, in the field of medium voltage switches, the spring operating mechanism is the most widely used mechanism, which mainly has the following two shortcomings: (1) The closing spring and the opening spring are independent of each other, and the energy storage mechanism only stores energy for the closing spring , when the switch is closed, the closing spring releases energy, and at the same time it stores energy for the opening spring to ensure that the switch can trip and open when it is closed. This kind of structural design needs to store energy for the opening spring when the closing spring releases energy at the same time, the structure is complex, the hidden danger of unsuccessful closing is great, and the reliability is low. If the energy storage of the opening spring fails, there w...
