Utility model content
The purpose of this utility model is: provide a kind of for the elbow-type end insulated end cover provision for disengagement in all insulation, totally enclosed ring main unit, it is ensured that at operation interval, maintainer's is perfectly safe.
For achieving the above object, the technical solution adopted in the utility model is: elbow-type end insulated end cover provision for disengagement, including insulation bull stick, the upper end of insulation bull stick is provided with inserting groove, inserting groove is that special-shaped slot and length direction are arranged along insulation bull stick length direction, being provided with for the dismantling spanner with dismounting insulated end cover in inserting groove, the lower end of insulation bull stick is provided with turning handle.
This utility model there is also following characteristics:
Being provided with cross bar on described turning handle, the bar length direction of described cross bar is vertical with the length direction of turning handle, and cross bar constitutes detachable cooperation with insulation bull stick.
The cross section of described inserting groove is hexagon, and described dismantling spanner is shaft-like, and dismantling spanner one end is arranged to constitute, with inserting groove, positive six prisms that grafting coordinates, and is filled with epoxy resin in the gap between inserting groove and dismantling spanner.
The upper end of insulation bull stick is provided with metal cap, is provided with protuberance in described metal cap, and the gap between metal cap and insulation bull stick is filled with epoxy resin.
Insulation bull stick lower end turning handle be tubular structure and with insulation bull stick lower rod end constitute grafting coordinates, turning handle is provided with pin, the rod end of pin with insulate bull stick outer wall against.
Being provided with set T-Ring on described cross bar, described set T-Ring and turning handle constitute grafting and are fastenedly connected.
Compared with prior art, the technique effect that this utility model possesses is: owing to end there may be the situation of electric leakage, therefore insulation bull stick and turning handle is used to drive dismantling spanner, guaranteeing rotation insulated end cover, guaranteeing while turn insulated end cover, also it is avoided that dismantling spanner produces touching with other parts of end, thus causes the situation of electric shock, so that it is guaranteed that the personal safety of maintainer.

Detailed description of the invention
In conjunction with Fig. 1 to Fig. 5, the utility model is further described:
Elbow-type end insulated end cover provision for disengagement, including insulation bull stick 10, the upper end of insulation bull stick 10 is provided with inserting groove 11, inserting groove 11 is that special-shaped slot and length direction are arranged along insulation bull stick 10 length direction, being provided with for the dismantling spanner 20 with dismounting insulated end cover in inserting groove 11, the lower end of insulation bull stick 10 is provided with turning handle 12.Owing to end there may be the situation of electric leakage, therefore insulation bull stick 10 and turning handle 12 is used to drive dismantling spanner 20, guaranteeing rotation insulated end cover, guaranteeing while turn insulated end cover, also it is avoided that dismantling spanner 20 produces touching with other parts of end, thus cause the situation of electric shock, so that it is guaranteed that the personal safety of maintainer.
Owing to insulated end cover is excessive with the air pressure of end, it is likely to occur situation about cannot pull, for increasing moment of torsion, described turning handle 12 is provided with cross bar 30, the bar length direction of described cross bar 30 is vertical with the length direction of turning handle 12, and cross bar 30 constitutes detachable cooperation with insulation bull stick 10.When needs increase moment of torsion, cross bar 30 is contained on turning handle 12, so that it is guaranteed that insulated end cover is disassembled from end, it is not necessary to time, cross bar 30 is disassembled.
Further, for guaranteeing the strong degree that inserting groove 11 coordinates with dismantling spanner 20, the cross section of described inserting groove 11 is hexagon, described dismantling spanner 20 is in shaft-like, dismantling spanner 20 one end is arranged to constitute positive six prisms that grafting coordinates with inserting groove 11, is filled with epoxy resin in the gap between inserting groove 11 and dismantling spanner 20.This epoxy resin can not only guarantee insulation, but also is able to ensure that bonding strength.
For the intensity of reinforced insulation bull stick 10, the upper end of insulation bull stick 10 is provided with metal cap 40, is provided with protuberance 41 in described metal cap 40, and the gap between metal cap 40 and insulation bull stick 10 is filled with epoxy resin.By the epoxy resin filled such that it is able to strengthen the chimeric strong degree of metal cap 40 and insulation bull stick 10.
For realizing the connection strong degree of turning handle 12 and insulation bull stick 10, the turning handle 12 of insulation bull stick 10 lower end is tubular structure and coordinates with the lower rod end composition grafting of insulation bull stick 10, be provided with pin on turning handle 12, the rod end of pin with insulation bull stick 10 outer wall against.
Further, described cross bar 30 being provided with set T-Ring 31, described set T-Ring 31 constitutes grafting with turning handle 12 and is fastenedly connected.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.
