Description
Technical field
The utility model relates to a kind of GIS device technical field, specifically a kind of delay switching device for GIS device operating mechanism.
Background technology
High pressure GIS device plays vital effect in operation of power networks, and its isolation, earthed switch divide-shut brake position signalling have the auxiliary switch in operating mechanism to provide at present.In order to ensure electrical network reliability service, present electrical network progressively requires that the divide-shut brake position signalling of switch will be sent after reliable deciliter of switch again.This just requires deciliter time that should be later than switch the change-over time of the auxiliary switch in operating mechanism, but does not also possess deferred mount in existing operating mechanism and solve this technical problem.
Summary of the invention
The utility model provides a kind of rational in infrastructure to overcome above-mentioned defect, guarantees that the action of operating mechanism auxiliary switch is later than the delay switching device of equipment divide-shut brake action.
The technical solution adopted in the utility model is: a kind of delay switching device for GIS device operating mechanism, it is characterized in that: comprise fanning strip, adjusting yoke and connecting plate, the lower end of described fanning strip is fixedly connected on the outer end of the final drive shaft of operating mechanism, the top of fanning strip is provided with sliding tray, this sliding tray is arcuation bar hole, the lower end of connecting plate is fixedly connected with auxiliary switch, auxiliary switch top is connected by adjusting yoke with fanning strip top, adjusting yoke is the telescopic structure of adjustable in length, its one end is articulated and connected by connecting pin and connecting plate, the other end is provided with pin, this pin inserts in sliding tray and also can slide along in sliding tray, adjusting yoke is flexibly connected with fan plate by pin.
As a kind of preferred structure of the present utility model, described adjusting yoke comprises two swivel nuts and a screw rod, screw rod is connected between two swivel nuts, and the outer end of a swivel nut is articulated and connected by connecting pin and connecting plate, and the outer end of another swivel nut is flexibly connected with fanning strip by pin.
The utility model is provided with fanning strip on the final drive shaft of operating mechanism, the top of fanning strip is provided with sliding tray, fanning strip is connected with the connecting plate be arranged on auxiliary switch by adjusting yoke, when operating mechanism drives fanning strip to rotate, the pin of adjusting yoke end slides along in sliding tray, until when pin slides into the end of sliding tray, fanning strip just can drive connecting plate to rotate by adjusting yoke, connecting plate now just can drive auxiliary switch action, so just, form the deferred action of auxiliary switch, realize the branch wire time being later than high-tension apparatus switch change-over time of the auxiliary switch in operating mechanism, thus ensure the reliability service of high-tension apparatus.The telescopic structure of adjustable in length is arranged to by adjusting yoke by the utility model, length adjustment is carried out according to the distance between connecting plate and fanning strip, to facilitate adjusting yoke and connecting plate and fanning strip to assemble, and make transmission more reliable by the length adjusting adjusting yoke.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Now by reference to the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, comprise fanning strip 1, adjusting yoke 2 and connecting plate 3, the lower end of described fanning strip 1 is fixedly connected on the outer end of the final drive shaft 4 of operating mechanism, the top of fanning strip 1 is provided with sliding tray, this sliding tray is arcuation bar hole, just drives fanning strip 1 to turn an angle when final drive shaft 4 rotates.The lower end of connecting plate 3 is fixedly connected with auxiliary switch 6, and connecting plate 3 is normally connected with the switch shaft of auxiliary switch 6, and connecting plate 3 rotates by driving switch shaft the action realizing auxiliary switch 6, namely promotes auxiliary switch 6 and changes.Auxiliary switch 6 top is connected by adjusting yoke 2 with fanning strip 1 top, adjusting yoke 2 is the telescopic structure of adjustable in length, its one end is articulated and connected by connecting pin 5 and connecting plate 3, the other end is provided with pin 7, this pin 7 inserts in sliding tray and also can slide along in sliding tray, and adjusting yoke 2 is flexibly connected with fan plate by pin 7.
In the present embodiment, described adjusting yoke 2 comprises two swivel nuts and a screw rod, and screw rod is connected between two swivel nuts, and the outer end of a swivel nut is articulated and connected by connecting pin 5 and connecting plate 3, and the outer end of another swivel nut is flexibly connected with fanning strip 1 by pin 7.Adjusting yoke 2 structure in the present embodiment is simple, and length adjustment all can be carried out in two ends, easy to operate.Adjusting yoke 2 in the utility model can also be arranged to other adjustable length section type structures, as a screw rod and a swivel nut carry out the structure or sleeve type structure etc. that are threaded.
The utility model is work like this: when operating mechanism carries out separating brake or closing operation, the final drive shaft 4 of operating mechanism can turn an angle, final drive shaft 4 drives fanning strip 1 to follow it simultaneously and rotates, due to fanning strip 1 being provided with sliding tray, when fanning strip 1 starts to rotate, the pin 7 of adjusting yoke 2 end slides along in sliding tray, fanning strip 1 does not now pull adjusting yoke 2 to move, until when pin 7 slides into the end of sliding tray, fanning strip 1 just can drive connecting plate 3 to rotate by adjusting yoke 2, connecting plate 3 now just can drive auxiliary switch 6 action, so just the deferred action of auxiliary switch 6 is formed, realize the branch wire time being later than high-tension apparatus switch change-over time of the auxiliary switch 6 in operating mechanism, thus ensure the reliability service of high-tension apparatus.When final drive shaft 4 rotate in place stop time, auxiliary switch 6 completes switching and sends switch divide-shut brake and to put in place signal, and now in switch, moving contact contacts with fixed contact already.Thus the requirement that the divide-shut brake position signalling meeting switch will be sent after reliable deciliter of switch again.
This device can ensure auxiliary switch 6 release signal again after facility switching contact reliable contacts, meets the up-to-date service requirement of electrical network.This device is arranged on that high pressure GIS isolates, in the operating mechanism of earthed switch, can avoid because switch contact does not reach an auxiliary switch 6 release signal and the serious accident that causes.
The utility model has rational in infrastructure, guarantees that operating mechanism auxiliary switch 6 action is later than the feature of equipment divide-shut brake action.
