Technical field

This utility model relates to electric power overhaul field of tool, is specifically related to a kind of elbow-type end insulated end cover dismounting and pulls Hands.

Background technology

Along with the development of distribution network technology, all insulation, totally-enclosed waterproofing design are outdoor ring main unit, cable branch box, case The developing direction of the equipment such as formula transformer station, above-mentioned all insulation, totally-enclosed greatly improve Reliability of Power Supplying Net Work and equipment peace Entirely, stable operating performance.The equipment such as totally-enclosed, all insulation formula outdoor ring main unit are largely used to urban distribution network, for improving power supply Reliability majority is designed to duplicate supply looped network and powers, and inlet wire cable is penetrated by lower cabinet door, for preventing the charged splice grafting of operations staff Ground disconnecting link maloperation, actual application mesohigh incoming line cabinet and contact cabinet do not fill grounding switch, and outgoing line cabinet installs grounding switch；Its Secondary, these are totally-enclosed, all insulation formula outdoor ring network cabinet equipment many employings all insulation, full-shield formula elbow-type tag, entirely Insulation elbow-type tag cannot install traditional earth lead without bare metal conductor, operation field.But, for In the equipment interruption maintenance operation process such as these are totally-enclosed, the distribution outdoor ring main unit of all insulation, there are some all insulations, entirely seal The inlet wire of the distribution outdoor ring main unit closing family is spaced no ground disconnecting link or bare metal earth point, and maintainer can only be by disconnecting In upper level or electric substation, the mode of switch the grounding switch that closes is to arrange site safety measure.Setting cannot be installed and connect Ground, field service personnel cannot definitely determine that operation interval is not charged, bring certain security risk to Field Force.Especially when When operating personnel dismantles all insulation formula elbow-type tag, because the electrical verification of safe distribution of electric power code requirement, installation cannot be accomplished Earth lead or grounding switch technology protection measure of closing, operating personnel is directly using the supporting metallic sheath of elbow-type cable terminal During barrel spanner dismounting insulated end cover, the person, electrical network are brought very big security risk.

Utility model content

The purpose of this utility model is: provide a kind of exhausted for the elbow-type end in all insulation, totally enclosed ring main unit Acies lid dismantling spanner, 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: the dismounting of elbow-type end insulated end cover is pulled Hands: including that the bull stick that insulate, the upper end of insulation bull stick are provided with inserting groove, inserting groove length direction is along insulation bull stick length side Be provided with in layout, inserting groove for insulated end cover against push rod, insulation bull stick lower end be provided with turning handle, top Bar constitutes feed screw nut with the screwed hole arranged on supporting plate and coordinates, and supporting plate is provided with two pull bars, the extension of described pull bar Direction is parallel with the bearing of trend of push rod, and the elongated end of pull bar is provided with and constitutes, with insulated end cover lid mouth, the hook that hook establishing is closed.

This utility model there is also following characteristics:

Wearing on described push rod and penetrated regulation pole, the bar length direction of described regulation pole is vertical with the length direction of push rod, Regulation pole is the both sides that two pull bars are stretched out at bolt and two ends, and two rod ends being positioned at regulation pole are provided with adjusting nut, are positioned at Being provided with spring on the regulation pole at place between pull bar and push rod, one end of pull bar constitutes linear slide with supporting plate and coordinates.

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, Cross bar constitutes detachable cooperation with insulation bull stick.

The cross section of described inserting groove is hexagon, and described push rod one end is arranged to constitute positive six that grafting coordinates with inserting groove Prism, is filled with epoxy resin in the gap between inserting groove and push rod.

The upper end of insulation bull stick is provided with metal cap, is provided with protuberance in described metal cap, and metal cap is with exhausted Gap between edge bull stick is filled with epoxy resin.

The turning handle of insulation bull stick lower end is tubular structure and coordinates with the lower rod end composition grafting of insulation bull stick, rotates Be provided with pin on handle, the rod end of pin with insulation 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 feelings of electric leakage Condition, therefore uses insulation bull stick to avoid dismantling spanner to produce touching with other parts of end, thus causes the situation of electric shock, Guarantee the person of maintainer, due between insulated end cover and end adhesive glue dry after, insulated end cover and end Axial friction is relatively big, and insulated end cover is extracted by manual being difficult to, utilize hook on pull bar and insulated end cover lid mouth constitute Coordinate, hand-held turning handle so that the rod end of push rod and insulated end cover against, be rotated further turning handle, thus by insulating end Lid is pulled up from end.
