Abstract
The invention discloses an auxiliary operation device for a disconnecting switch of a transformer substation. The auxiliary operation device comprises a sleeve. An insertion rod is arranged at one end of the sleeve and is connected with the end in a sliding mode. An insertion rod locating device is arranged on the sleeve. A clamping sleeve is arranged in the port of the other end of the sleeve and comprises a sleeve ring and an arc-shaped rib which are connected into a whole, wherein the arc-shaped rib is an elastic body and dents inwards in an arc shape. A clamping groove is formed in the inner wall of the sleeve, and the sleeve ring at the outer end of the clamping sleeve is connected into the clamping groove in a clamped mode. A compressed spring is arranged between the inner end of the insertion rod and the clamping sleeve. The auxiliary operation device is used for closing or opening the disconnecting switch of a power supply circuit. When the auxiliary operation device is used, the sleeve is connected to a disconnecting switch operating rod in a sleeved mode, the insertion rod is pushed inwards and located, and then closing or opening of the disconnecting switch operating rod is carried out. Because the sleeve and the disconnecting switch operating rod are tightly connected together, the situation that the sleeve slips off because of inertia is avoided, and the auxiliary operation device is safe to use. After the operation, the insertion rod is dislocated from the sleeve and returns under the action of the spring, and then the sleeve is dismounted. The auxiliary operation device is convenient to use.
Description
Technical field
The invention belongs to supply line's isolation switch operating means technical field, especially a kind of servicing unit of being convenient to isolation switch to divide closing operation.
Background technology
Isolating switch is one of visual plant of transformer station, the many and frequent operation of quantity, and these switch isolation switch are arranged on outdoor equipment more.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, the strength that operating personnel need to cost a lot of money, even needing in double harness could complete operation.The problem being difficult to deciliter for solving grid switching operation, 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 owing to being subject to the restriction of equipment and site condition, auxiliary sleeve pipe can not be oversize; And serious when running into connecting rod jam, need operate by larger strength, the moment of pulling open at disconnecting link, be subject to inertia effects, auxiliary sleeve pipe tends to the slippage of taking advantage of a situation, and the personnel that easily cause fall down.This is not only bad for handling safety, but also can cause isolating switch 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 a kind of being convenient to knife break operating level is carried out to pulling, and uses safe transformer station's isolation switch backup actuating device.
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 that slip is joined with it, described sleeve is provided with inserted link positioner, in the port of the sleeve other end, is provided with retaining sleeve, and described retaining sleeve comprises the collar and the arcuate rib being connected, described arcuate rib is that elastomer indent are curved, sleeve lining is provided with draw-in groove, and the collar of retaining sleeve outer end is connected in draw-in groove, between inserted link inner termination and retaining sleeve, is provided with stage clip.
Preferably described positioner comprises grooved rail and backing pin, and described grooved rail is located in sleeve wall also L-shaped, and described backing pin is located on inserted link and with it and lives and connect, and backing pin and grooved rail slide and join.
Further preferably described sleeve is provided with display unit, and the collar of retaining sleeve the inner is provided with the contact-making switch of 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: in sleeve of the present invention, be provided with retaining sleeve, 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 that is provided with retaining sleeve is connected on knife break operating level, after making knife break operating level insert 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, the arcuate rib of retaining sleeve clamps knife break operating level tightly, and sleeve and knife break operating level are linked into an integrated entity.At this moment, rotate inserted link and fix behind its position, just can operate.After knife break operating level pulling, sleeve pipe can, because of inertia slippage, not use safety.After having operated, then rotate inserted link itself and sleeve are removed behind location, 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, in the port of sleeve 1 one end, be provided with the insulation inserted link 2 that slip is joined with it, inserted link 2 external end heads are provided with handle 21, and inserted link 2 is connected with handle 21 is T-shaped.On sleeve 1, be provided with the fixedly positioner 5 of inserted link 2 positions, 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 shaped hole on sleeve 1 wall, and backing pin 52 is located on inserted link 2 and is threaded with it, and backing pin 52 slides and joins with grooved rail 51.51 spacing and positioning actions of grooved rail, utilize fixedly inserted link 2 positions of backing pin 52 and grooved rail 51.In the port of sleeve 1 other end, be provided with retaining sleeve 3, retaining sleeve 3 comprises the collar 31 and the arcuate rib 32 being connected, and arcuate rib 32 is elastomer and curved indent, makes retaining sleeve 3 integral body be middle thin card waist shape.Sleeve 1 inwall is provided with draw-in groove 7, and the collar 31 of retaining sleeve 3 external end heads is connected in draw-in groove 7,7 pairs of retaining sleeves of draw-in groove, 3 its position-limiting actions.3 of inserted link 2 inner termination and retaining sleeves have been provided with the stage clip 4 of afterburning and reset response.
The accuracy of pegging graft for improving inserted link, the sleeve 1 of embodiment shown in figure is provided with display unit 8, display unit 8 be LED light or (with) buzzing sound display unit, display unit 8 bottoms are provided with dc-battery.The collar 31 of retaining sleeve 3 the inners is provided with the contact-making switch 6 of controlling display unit 8.Contact-making switch 6 is connected with the collar 31 elasticity.During use, in knife break operating level inserts retaining sleeve and while joining with contact-making switch 6, circuit is connected, and display unit 8 work, at this moment just can promote the further clamp operation bar of inserted link 2, operate accurate.
