Embodiment
Combine accompanying drawing that the utility model is further described, the technical scheme of the utility model is at present: a kind of divide-shut brake mechanical stop limiter of 550kV circuit breaker comprises pin 1, connecting rod 2, flange 12, connecting pin 3 and insulated tension pole 4; Connecting rod 2 one ends are connected with mechanism through pin 1, and the other end is connected with insulated tension pole 4 through connecting pin 3, and flange 12 is set in the outside of connecting rod 2; Flange 12 is connected with capping, and described pin 1 is provided with platen 10, and platen 10 is positioned at the junction of pin 1 and connecting rod 2; Platen 10 is in the form of annular discs; And with the axis normal of pin 1, on platen 10, be provided with projection near that side of connecting rod 2.In the left side of flange 12 sealing flange 5 is set, the arranged outside of sealing flange 5 has rubber blanket 8, and rubber blanket 8 is adaptive with the bump position on the platen 10.
The right side of flange 12 is provided with convex cone flange 6, and it is conical that convex cone flange 6 outsides are, and promptly the right side is convex cone shaped, and its front end face is provided with projection, and these convex cone flange 6 right sides are provided with the concave cone flange 7 that is mated.Connecting pin 3 one ends stretch in the connecting rod 2 and are connected with connecting rod 2, and the other end stretches into that insulated tension pole 4 is interior to be connected with insulated tension pole 4, and the middle part of connecting pin 3 is provided with terminal pad 11, and terminal pad 11 is also in the form of annular discs, and with the axis normal of connecting pin 3.Terminal pad 11 right sides and the insulated tension pole 4 of connecting pin 3 are close to, and the left side of terminal pad 11 is connected with described concave cone flange 7, and concave cone flange 7 is connected with terminal pad 11 through bolt.Left side at terminal pad 11 also is provided with rubber ring 9; Rubber ring 9 is adaptive with the bump position on convex cone flange 6 front end faces; Usually convex cone flange 6 is enclosed within the outside of rubber ring 9; See Fig. 3, the interior hole dimension of concave cone flange 7 is corresponding with convex cone flange 6 front end face excircle dimensions, and the projection on convex cone flange 6 front end faces just in time can be inserted on the inboard rubber ring 9 in concave cone flange 7 holes.Connecting rod 2 passes sealing flange 5, flange 12 and convex cone flange 6 successively, and its right-hand member is connected with insulated tension pole 4 through connecting pin 3, and mechanism laterally moves through pin 1 drivening rod 2.
In the present embodiment, the projection on pin 1 platen 10 is annular, and the rubber blanket 8 on the sealing flange 5 also is corresponding annular.In the present embodiment, the projection of convex cone flange 6 front ends is an annular, and the rubber ring 9 in terminal pad 11 left sides also is corresponding annular.Usually the area of rubber blanket 8 and rubber ring 9 is greater than the area of joining projection, vibration damping and good buffer effect like this.The projection of platen 10 and convex cone flange 6 front ends can also be other shapes in the utility model, is evenly distributed on platen 10 right flanks and the convex cone front end face like four column-like projection blocks.
In the breaker structure of the utility model, mechanism adopts the hydraulic spring grease cup operating mechanism usually, and this mechanism is connected with insulated tension pole 4 through pin 1, connecting rod 2, realizes the transmission of motion, and flange 12 passes through Bolt Connection with capping, and capping is connected with tank body.The sealing flange 5 and the convex cone flange 6 of flange 12 both sides all is fixing through bolt and flange 12, and above part is fixture, plays spacing effect.Pin 1 all is threaded with insulated tension pole 4 with connecting pin 3, connecting pin 3 with connecting rod 2, connecting rod 2, and concave cone flange 7 is connected with connecting pin 3 through bolt, and above part has constituted the moving-member of an integral body.
When the utility model closed a floodgate, as shown in Figure 1, circuit breaker began to close a floodgate after receiving reclosing command, and mechanism drives insulated tension pole 4 high-speed motion to the right through pin 1 and connecting rod 2.When pin 1 moved right to sealing flange 5 places, because the effect of in-house hydraulic damping, the speed of moving-member was smaller; Projection on the platen 10 of pin 1 at first can contact with rubber blanket 8, and through the compression of rubber blanket 8, moving-member obtains buffering; Speed reduces gradually; Contact and stop motion fully with sealing flange 5 until pin 1, see Fig. 2, so just avoided the mechanical collision of moving member and fixture.
During separating brake, as shown in Figure 3,, circuit breaker begins separating brake after receiving the separating brake instruction from closing position, and it is the left side high-speed motion to that side of mechanism that mechanism drives insulated tension pole 4 through pin 1 and connecting rod 2.Since rubber ring 9 and concave cone flange 7 are installed on the insulated tension pole 4 left side terminal pads 11, therefore, when concave cone flange 7 and rubber ring 9 move to convex cone flange 6 places; Same because the effect of hydraulic operating mechanism internal hydraulic pressure damping; The speed of moving-member is smaller, and rubber ring 9 can be at first is that the projection of right-hand member contacts with convex cone flange 6 front ends, sees Fig. 4; Compression through rubber blanket 8 circles; Reduce the speed of moving-member, reduced the active force of moving-member, contact fully with concave cone flange 7 and static until convex cone flange 6 to convex cone flange 6 and flange 12.Simultaneously since convex cone flange 6 and concave cone flange 7 cooperated guiding and fixed acting on, insulated tension pole 4 can not influence the separating brake effect owing to rocking radially when having guaranteed separating brake, guarantees divide-shut brake stable action, reliably.
The utlity model has rational in infrastructurely, alleviate impulsive force, the characteristics of stable action.
