The dual-auxiliary switch transmission device comprises a straight pull rod, a lower pull rod, a large fan-shaped plate and a small fan-shaped plate; two auxiliary switches are arranged up and down; the output shaft of the upper auxiliary switch is connected with the inner end of the large fan-shaped plate; the output shaft of the lower auxiliary switch is connected with the inner end of the small fan-shaped plate; the outer end of the large fan-shaped plate is hinged with the straight pull plate; the other end of the straight pull rod is hinged with a mechanism crank arm; an inner hole is also formed in the middle of the large fan-shaped plate; a pull rod is hinged in the inner hole; the lower end of the pull rod is hinged with an outer hole in the outer end of the small fan-shaped plate; and the distance from the rotating center to the inner hole of the large fan-shaped plate is equal to the distance from the rotating center to the outer hole of the small fan-shaped plate. The dual-auxiliary switch has the characteristics of simple structure, convenience in installation, stability in transmission and high synchronicity.
Description
Technical field
The utility model relates to a kind of technical field of power system device, specifically a kind of two auxiliary switch transmission devices that are applied in the potting breaker mechanism case.
Background technology
Potting breaker uses more extensive in high-voltage fence now, it has become one of indispensable component devices in the electric power system, the control loop of potting breaker is as using two auxiliary switches, all need to be installed in the mechanism case, traditional mounting means is that two auxiliary switches are connected with the mechanism connecting lever respectively, and floor space is big in mechanism case, and difficulty is installed, and use element more, transmission is complicated.Now the potting breaker demand strengthens gradually, seeks a kind of easy for installationly, and the simple novel kind of drive of transmission becomes the technical issues that need to address.
Summary of the invention
The utility model provides a kind of simple in structure, easy for installation in order to overcome above-mentioned defective, and transmission is stable, two auxiliary switch transmission devices that synchronism is good.
The technical solution adopted in the utility model is: a kind of pair of auxiliary switch transmission device, it is characterized in that: comprise Drag link, lower link, big fanning strip and little fanning strip, two auxiliary switches are arranged above and below, the output shaft of wherein going up auxiliary switch is connected with the inner of big fanning strip, the output shaft of following auxiliary switch is connected with the inner of little fanning strip, the outer end and the Drag link of described big fanning strip are articulated and connected, the other end of Drag link and mechanism's connecting lever are articulated and connected, middle part at big fanning strip also is provided with endoporus, the pull bar that is articulated and connected is set in the endoporus, the outer hole of the outer end of pull bar lower end and little fanning strip is articulated and connected, and the center of rotation of big fanning strip equates with the distance of little fanning strip center of rotation to outer hole to the distance of endoporus.
In the utility model, fixed head is set in mechanism, two auxiliary switches are installed in the upper and lower of fixed head respectively, and the output shaft of two auxiliary switches is parallel and be positioned on the same upright plane.
The utility model design utilizes two fanning strips to be connected with two auxiliary switches, the outer end of one of them fanning strip is articulated and connected by Drag link and mechanism's connecting lever, be articulated and connected by lower link between two fanning strips, and the center of rotation of two fanning strips equates with the distance that is connected of lower link, can realize that like this Drag link drives two fanning strips simultaneously and rotates, and the rotational angle of two fanning strips is identical, has guaranteed the synchronism of two auxiliary switch actions.The utility model is simple in structure, has reduced the composition of parts, and is easy for installation, and transmission is stable, and the synchronism of two auxiliary switches is good.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
Embodiment
Now in conjunction with the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, comprise Drag link 4, lower link 7, big fanning strip 6 and little fanning strip 10, two auxiliary switches are arranged above and below, the output shaft of wherein going up auxiliary switch 5 is connected with the inner of big fanning strip 6, the output shaft of following auxiliary switch 8 is connected with the inner of little fanning strip 10, and two fanning strips are all outward-dipping.The outer end of described big fanning strip 6 and Drag link 4 are articulated and connected, the other end of Drag link 4 and mechanism's connecting lever 2 are articulated and connected, middle part at big fanning strip 6 also is provided with endoporus, the lower link 7 that is articulated and connected is set in the endoporus, the outer hole of the outer end of lower link 7 lower ends and little fanning strip 10 is articulated and connected, usually in the junction of lower link 7 and little fanning strip 10 joint 9 is set, be that lower link 7 is connected with little fanning strip 10 by joint 9, for convenience detach and the assembling of this structure, equally, joint also can be set is connected with big fanning strip 6 with mechanism connecting lever 2 respectively at the two ends of Drag link 4.The center of rotation of described big fanning strip 6 equates with the distance of little fanning strip 10 centers of rotation to outer hole to the distance of endoporus.In the present embodiment, 11, two auxiliary switches of fixed head that level is set in mechanism are installed in the upper and lower of fixed head 11 respectively, and the output shaft of two auxiliary switches is parallel and be positioned on the same upright plane.
Because big fanning strip 6 endoporus of the utility model design are identical to the distance of little fanning strip 10 centers of rotation with little fanning strip 10 outer holes to the distance of big fanning strip 6 centers of rotation, when the utility model uses, work as mechanism action, mechanism's connecting lever 2 drives big fanning strip 6 actions by Drag link 4, meanwhile, big fanning strip 6 drives little fanning strip 10 actions by lower link 7, and guarantees that two auxiliary switches move simultaneously, and rotational angle is also identical, thereby has realized two auxiliary switch Synchronous Transmission.
The utlity model has simple in structurely, easy for installation, transmission is stable, the characteristics that synchronism is good.
