Abstract
The invention discloses a kind of transformer station isolation switch backup actuating device, comprise sleeve, one end of sleeve is provided with the inserted link sliding with it and connect, described sleeve is provided with inserted link positioner, is provided with retaining sleeve in the port of the sleeve other end, and described retaining sleeve comprises the collar and arcuate rib that are connected, described arcuate rib is elastomer and indent is curved, sleeve lining is provided with draw-in groove, and the collar of retaining sleeve outer end is connected in draw-in groove, is provided with stage clip between inserted link inner termination and retaining sleeve.The present invention is used for the pulling of supply line's isolation switch, during use, is connected on by jacket casing on knife break operating level, is then inwardly promoted by inserted link and after locating, then carries out the pulling of knife break operating level.Due to sleeve pipe and fastening the linking together of switch operation handle, sleeve pipe can not because of inertia slippage, use safety.After having operated, inserted link and sleeve remove and locate after under stage clip effect return, then take off sleeve, easy to use.
Description
Technical field
The invention belongs to supply line's isolation switch operating means technical field, be especially a kind ofly convenient to servicing unit isolation switch being carried out to point closing operation.
Background technology
Isolating switch is one of visual plant of transformer station, and the many and frequent operation of quantity, on these switch isolation switch equipment how disposed in the outdoor.In outdoor environment, switch isolation switch is through long-time running and wind and weather, and the linkage of disconnecting link handle can cause bite and retardance because of corrosion.When disconnecting link carries out deciliter operational motion, operating personnel need the strength costed a lot of money, and even needing in double harness could complete operation.For solving the problem that grid switching operation is difficult to deciliter, what have utilizes casing pipe sleeve on knife break operating level, utilizes the method for Lengthened moment arm to carry out pulling action bars.But due to the restriction by equipment and site condition, auxiliary sleeve pipe can not be oversize; And serious when run into connecting rod jam, need operate by comparatively great, in the moment that disconnecting link pulls open, by inertia effects, auxiliary sleeve pipe is often taken advantage of a situation slippage, and the personnel that easily cause fall down.This is not only bad for handling safety, but also isolating switch can be caused to support porcelain insulator breaking, injures operating personnel by a crashing object, causes security incident.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and is convenient to carry out pulling to knife break operating level, and transformer station's isolation switch backup actuating device of use safety.
For solving the problems of the technologies described above, the present invention includes sleeve, its design feature is that one end of sleeve is provided with the inserted link sliding with it and connect, described sleeve is provided with inserted link positioner, is provided with retaining sleeve in the port of the sleeve other end, and described retaining sleeve comprises the collar and arcuate rib that are connected, described arcuate rib is elastomer and indent is curved, sleeve lining is provided with draw-in groove, and the collar of retaining sleeve outer end is connected in draw-in groove, is provided with stage clip between inserted link inner termination and retaining sleeve.
Preferably described positioner comprises grooved rail and backing pin, and described grooved rail to be located in sleeve wall and L-shaped, and described backing pin to be located on inserted link and to live with it and connects, and backing pin slides with grooved rail and connects.
Further preferably described sleeve is provided with display unit, and the collar of retaining sleeve the inner is provided with the contact-making switch controlling display unit circuit.
Described display unit is light or sound display unit, and contact-making switch is connected with cover ring resilience, is provided with circuit power in display unit.
Described inserted link external end head is provided with handle.
Beneficial effect of the present invention is: be provided with retaining sleeve in sleeve of the present invention, and the sleeve other end is provided with inserted link, is also provided with stage clip between inserted link and retaining sleeve.During use, the socket end headgear being provided with retaining sleeve is connected on knife break operating level, knife break operating level is inserted after in retaining sleeve, more inwardly promotes inserted link.Because retaining sleeve is provided with flexible arcuate rib, when inserted link inwardly promotes, through the further press nip cover of stage clip, knife break operating level clamps by the arcuate rib of retaining sleeve tightly, and sleeve and knife break operating level are linked into an integrated entity.At this moment, after its position fixed by rotation inserted link, just can operate.After knife break operating level pulling, sleeve pipe can not because of inertia slippage, use safety.After having operated, then rotate after inserted link makes itself and sleeve remove to locate, inserted link is return under stage clip effect just, and then extracts sleeve, easy to use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is overall schematic of the present invention;
Fig. 2 is cutaway view of the present invention;
Fig. 3 is circuit diagram of the present invention.
Embodiment
With reference to accompanying drawing, the present invention includes the insulating sleeve 1 with some strength, be provided with the insulation inserted link 2 sliding with it and connect in the port of sleeve 1 one end, inserted link 2 external end head is provided with handle 21, and inserted link 2 is connected with handle 21 is T-shaped.Sleeve 1 is provided with the positioner 5 of fixing inserted link 2 position, the positioner 5 of embodiment shown in figure comprises grooved rail 51 and backing pin 52, grooved rail 51 is for being located at the L shape hole on sleeve 1 wall, and backing pin 52 is located on inserted link 2 and is also threaded with it, and backing pin 52 slides with grooved rail 51 and connects.Grooved rail 51 spacing and positioning actions, utilize backing pin 52 and grooved rail 51 can fix inserted link 2 position.Be provided with retaining sleeve 3 in the port of sleeve 1 other end, retaining sleeve 3 comprises the collar 31 and arcuate rib 32 that are connected, and arcuate rib 32 is elastomer and curved indent, makes retaining sleeve 3 entirety in middle thin card waisted.Sleeve 1 inwall is provided with draw-in groove 7, and the collar 31 of retaining sleeve 3 external end head is connected in draw-in groove 7, draw-in groove 7 pairs of its position-limiting actions of retaining sleeve 3.Stage clip 4 that is afterburning and reset response has been provided with between inserted link 2 inner termination and retaining sleeve 3.
For improving the accuracy of inserted link grafting, the sleeve 1 of embodiment shown in figure is provided with display unit 8, display unit 8 be LED lamplight or (with) buzzing sound display unit, be provided with dc-battery bottom display unit 8.The collar 31 of retaining sleeve 3 the inner is provided with the contact-making switch 6 controlling display unit 8.Contact-making switch 6 is connected with the collar 31 elasticity.During use, when knife break operating level to insert in retaining sleeve and when connecting with contact-making switch 6, circuit ON, display unit 8 works, and at this moment just can promote inserted link 2 clamp operation bar further, operate accurate.
