Abstract
The utility model belongs to high voltage power transmission and distribution devices and relates to a ground switch actuating mechanism which is used in a switch cabinet. The ground switch actuating mechanism comprises a front panel, a rear wallboard and a baffle plate which form a lower cabinet of the switch cabinet, wherein a main switch actuating shaft is installed between the front panel and the baffle plate, the height of the main switch actuating shaft is higher than a ground switch main shaft, the rear end of the main switch actuating shaft is connected with an upper turning arm, a ground switch actuating shaft is installed between the baffle plate and the rear wallboard, the height of the ground switch actuating shaft is lower than the ground switch main shaft, the front end of the ground switch actuating shaft is connected with a turning arm, the upper turning arm and a lower turning arm are located on one side of baffle plate, a transition connecting bar is hinged between the upper turning arm and the lower turning arm, and the rear end of the ground switch actuating shaft drives the ground switch main shaft on the ground switch actuating shaft. The ground switch actuating mechanism can guarantee the insulation distance between the actuating mechanism and each conductive part of the ground switch and can increase the operation stability of the switch cabinet.
Description
Technical field
The utility model belongs to the high pressure equipment for power transmission and distribution, relates to a kind of earthed switch operating mechanism that is used for switch cubicle.
Background technology
The following cabinet of common high-tension switch cabinet includes front panel, squab panel and separates the dividing plate between the plate and squab panel in front, dividing plate will play cabinet to be divided into former and later two parts, the anterior main switch of installing, earthed switch is installed at the rear portion, existing structure such as accompanying drawing 1, the shared control lever shaft C of main switch and earthed switch, this control lever shaft run through at following cabinet middle part front panel 1 ', dividing plate 3 ' and squab panel 2 ', when by control lever shaft main switch being handled, the back segment of control lever shaft is positioned at the earthed switch main shaft 8 ' synchronization action of control lever shaft below by connecting rod 10 ' driving.In this structure, because each phase current-carrying part of earthed switch is positioned at earthed switch main shaft top, with control lever shaft and connecting rod close together, its insulation distance is difficult for guaranteeing the reliability of the equipment operation of reduction.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of guarantee operating mechanism and earthed switch each mutually current-carrying part insulation distance, improve the earthed switch operating mechanism of switch cubicle operational reliability.
Earthed switch operating mechanism of the present utility model includes front panel, the squab panel of forming cabinet under the switch cubicle and separates the dividing plate between the plate and squab panel in front; A main switch control lever shaft that is used for driving main switch is installed between plate and the dividing plate in front, and the height and position of main switch control lever shaft is higher than the earthed switch main shaft, and the rear end of main switch control lever shaft is connected with one and goes up connecting lever; An earthed switch control lever shaft is installed between dividing plate and squab panel, and the height and position of earthed switch control lever shaft is lower than the earthed switch main shaft, and the front end of earthed switch control lever shaft is connected with a following connecting lever; The described connecting lever of going up is positioned at the same side of dividing plate with following connecting lever, and is hinged with a transition connecting rod between upper and lower connecting lever; The rear end of earthed switch control lever shaft drives the earthed switch main shaft that is positioned at earthed switch control lever shaft top by connecting rod.
The utility model is owing to be arranged on earthed switch main shaft below also by transition connecting rod and the interlock of main switch control lever shaft with the earthed switch control lever shaft, not only guaranteed the interlock of main switch and earthed switch, the operation part of earthed switch mainly is positioned at earthed switch main shaft below simultaneously, each phase current-carrying part away from earthed switch, thereby be easy to guarantee insulation distance, improved the operational reliability of switch cubicle.
