Pull rod corresponds and drives the transmission shaft connecting lever of corresponding insulated pull rod movement, and insulated pull rod extends perpendicularly to be driven
Axis, the frame are equipped with support knot of the radial side in transmission shaft in breaker closing with transmission shaft support cooperation
Structure, support construction include at least two rotatable supports along transmission shaft circumferentially, and the rotatable support and transmission shaft roll
Dynamic cooperation, support construction support transmission shaft in breaker closing by rotatable support.
The beneficial effect of breaker of the invention is：Only pass through bearing to transmission in both ends of the drive shaft compared to the prior art
Axis is supported, and breaker of the invention in both ends of the drive shaft in addition to that can be supported, additionally it is possible to pass through support construction in centre
It is supported, reduces transmission shaft because deforming caused by the effect by insulated pull rod power, and support construction is equipped with and transmission
The rotatable support that axis is rotatably assorted can rotate with it in transmission shaft rotation, will not influence the rotation of transmission shaft, so support
Structure can reduce transmission shaft because of the influence caused by deforming to breaker performance.
Further, for the ease of support construction is arranged, the rotatable support is idler wheel.
Further, for the ease of support construction is arranged, the support construction includes the removable fixation being fixed on frame
Block, idler wheel rolling assembling is on the fixed block.
Further, fixed block be equipped with square groove, idler wheel rolling assembling in square groove, idler wheel protrude square groove notch setting with
It rolls and cooperates with transmission shaft.
Further, for simplified support structure, the idler wheel is arranged two.
Further, it in order to keep stressed transmission shaft uniform, is respectively provided between adjacent transmission shaft connecting lever on transmission shaft
The support construction stated.

Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
The specific embodiment of breaker of the invention, as shown in Figures 2 to 6, the breaker in the present invention are side-mounted disconnected
Road device, the breaker include the frame 1 being vertically arranged on switchgear, and 1 two sides of frame are equipped with side wall, wherein the side wall peace of side
Equipped with operating mechanism 2, the transmission mechanism of arc-chutes 6 and attended operation mechanism 2 and arc-chutes 6 is also equipped on frame 1.
Transmission mechanism includes the transmission shaft 3 for being horizontally set on 1 top of frame, and transmission shaft 3 is equipped with transmission shaft connecting lever 4, is passed
One end of insulated pull rod 5 is hinged on moving axis connecting lever 4, and the insulated pull rod other end is connect with the arc-chutes connecting lever on arc-chutes 6.Insulation
Pull rod 5 includes two connectors, and two connector activities are assembled together, and are provided with spring between two connectors.Carry out
During combined floodgate, as transmission shaft rotates, transmission shaft applies the spring in insulated pull rod 5 by transmission shaft connecting lever 4 continuous
The pressure of increase simultaneously reaches maximum when combined floodgate finishes, and spring force can be such that the indoor moving contact of arc extinguishing and static contact cooperates
Stablize, but spring also can apply pressure, the 3 long-time stress of transmission shaft of breaker to transmission shaft 3 by transmission shaft connecting lever 4 simultaneously
Deformation occurs for meeting, and the transmission shaft 3 for generating deformation then will affect the stability of breaker.
In order to reduce the deformation of transmission shaft 3, the present embodiment is fixed on frame 1 equipped with removable between transmission shaft 3 and frame 1
