The present embodiment is a kind of easy-to-install high-voltage mutual inductor, sees shown in Fig. 1 to Fig. 5, comprises that matrix 1, one are flatFace nut 2, two casing pressure claw assemblies 3 and a transformer 7; Each casing pressure claw assembly comprises three paws 4; Matrix is provided with cunningPipe 11 and be arranged on the radially-directed spacing hole 12 on slip pipe; Radially-directed spacing hole radially runs through sliding along matrix slip pipeTube wall; Radially-directed spacing hole 12 is positioned at the edges at two ends place of matrix slip pipe on axially;
The quantity of radially-directed spacing hole 12 is identical with the quantity of paw 4, and totally six, the two ends on matrix slip pipe is axialThree radially-directed spacing holes are respectively set, and these three radially-directed spacing holes are used for and corresponding a set of paw assembly 3 adaptations;Each paw is arranged in a corresponding radially-directed spacing hole 12, and each paw is in the guide and limit effect of radially-directed spacing holeLower radially reciprocatingly sliding along matrix slip pipe 11;
Plane nut 2 be shaped as ring-type, plane nut sleeve is located on the periphery wall of matrix slip pipe 11, and is positioned at two coversBetween paw assembly 3;
The guide runner portion 43 that each paw is provided with pressing plate portion 41, radially extend to form along matrix slip pipe 11 and being arranged on leadsTo the driving threaded portion 44 in slide section; Drive threaded portion 44 to be arranged on a side of guide runner portion adjacent flat nut;The inwall of pressing plate portion is curved, forms a deep-slotted chip breaker 45, and the deep-slotted chip breaker of multiple paws encloses and forms a clamp hole 5. ExternalCable is arranged in this clamp hole 5.
The present embodiment, in order to connect electricity from insulating power cable, is also provided with multiple punctures 42 on pressing plate portion inwall, specifically comesSay, puncture is arranged on the inwall of each deep-slotted chip breaker, respectively punctures along matrix slip pipe 11 radially to projecting inward. The existence of puncture,Can, in the time insulating power cable not being carried out to peeling processing, still can effectively connect electricity. In concrete practice, if clampBe bare wire, puncture can be set.
In the present embodiment, each paw is the integral piece of making by cast molding, and each puncture is made in the time of cast molding; ?In concrete practice, puncture also can adopt alternate manner to make; For example on the inwall of pressing plate portion, be provided with multiple installation draw-in grooves,Then install in draw-in groove be inlaid in corresponding one by the die-cut puncture sheet of making, puncture sheet comprises installation portion and thorn swordPortion, installation portion is inlaid in to be installed in draw-in groove, and thorn blade exposes installing card groove and forms puncture. The benefit of this structure is to wearThorn sheet can adopt the material different with paw to make, and especially selects and treats that clamp cable same material used makes, favourableIn obtaining better electrical gas performance.
The internal perisporium of plane nut is and the smooth inner wall of matrix slip pipe periphery wall adaptation that the periphery wall of plane nut is provided withFastening part 21, plane nut is provided with a flat thread portion 22 separately in the two side ends on axial along matrix slip pipe, each flatFace threaded portion is provided with archimedean spiral groove, each flat thread portion with the driving of three paws in a set of paw assemblyThe engagement of moving threaded portion is adaptive; The fastening part 21 of the present embodiment midplane nut be arranged on plane nut periphery wall outsideHexagonal shape fastener head, it is twisted operation and adopts inner hexagon spanner, shfting wrench or fork spanner; In concrete practice, described inFastening part just can adopt other shape, for example, adopt the multiple binding grooves that are evenly distributed on plane nut periphery wall, and it is twistedTurn operation and adopt hook type spanner (being commonly called as hook spanner).
In the present embodiment, each radially-directed spacing hole 12 comprises rectangle slide opening 121 and anticreep slide opening 122, and rectangle slide opening is establishedPut the edge at matrix slip pipe, form a breach, anticreep slide opening and rectangle slide opening are communicated with, and it is sliding that anticreep slide opening is positioned at rectangleThe inboard in hole, anticreep slide opening and rectangle slide opening are combined to form T font hole;
Each paw guide runner portion 43 be provided be arranged in rectangle slide opening guide part 431, be arranged in the anti-delinking part of anticreep slide opening432 and be positioned at the limiting section 433 in matrix slip pipe outside, guide part 431, anti-delinking part 432 and the limiting section of each paw433 cross sectional shapes that are combined to form are I-shaped; The guide part 431 of each paw and anti-delinking part 432 are along the footpath of matrix slip pipeTo running through each paw, on the inwall of the inwall of the guide part 431 of each paw, the inwall of anti-delinking part 432 and pressing plate portion 41Be equipped with multiple punctures; Drive threaded portion to be arranged on a side wall of anti-delinking part adjacent flat nut, the shape of anti-delinking partWith anticreep slide opening adaptation; Drive threaded portion to protrude and be arranged on a side wall of anti-delinking part adjacent flat nut, thereby makeDrive threaded portion can not move in anticreep slide opening.
In the present embodiment, the direction of rotation of the flat thread portion of plane nut one side is forward, the plane spiral shell of another sideThe direction of rotation of line portion is oppositely, the direction of rotation of the driving screw thread on each paw be with the flat thread of this paw adjacencyThe direction of portion's adaptation. When this structure makes plane nut rotation, by two flat thread portions of its two side ends, synchronousDriving two casing pressure claw assemblies to realize clamps or releases cable.
In the present embodiment, transformer 7 is annular voltage transformer; Plane nut periphery wall is provided with a detent, shouldTransformer is fixedly installed in detent, and plane fastening nuts portion respectively establishes on the periphery wall that is positioned at these detent both sidesThere is one to twist fastening part; This voltage transformer, for inducing lower secondary voltage from folded cable, is used to itIts auxiliary equipment for example camera, temperature sensor, wireless transmit/receive units provide electric energy.
The present embodiment, in the time carrying out clamp operation, adopts inner hexagon spanner, shfting wrench or fork spanner to twist plane nut;Plane nut, in reciprocating rotation, drives its flat thread portion reciprocating rotation, and then by engage the driving spiral shell of adaptation with itLine portion drives the synchronous two casing pressure claw assemblies that drive, because each paw is under the guide and limit effect of radially-directed spacing hole 12Can only, along radially the moving back and forth of matrix slip pipe, be to lean on each other towards slip pipe center thereby make the move mode of each pawNear or away from, thereby clamp or unclamp the electric power cable that is arranged in clamp hole 5.
The present embodiment is by clamping cable at the longitudinal center line place that is arranged on high-voltage mutual inductor, and its gravity centre distribution is comparatively closedReason, on for high-altitude overhead power line time, is conducive to alleviate vibration; In addition, the present embodiment is by flat thread portionDrive paw to clamp electric power cable, clamp electric power cable with the bolt assembly by traditional and compare, outstanding in anti-loosening effectFor excellence, effectively ensure the reliability of long-term work.
In the present embodiment, two casing pressure claw assemblies are clamped on same cable, have the effect of dual fail-safe, even wherein a set ofIn use go wrong, also have its service behaviour of another set of guarantee.
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not to thisThe restriction of working of an invention mode. For those of ordinary skill in the field, also can on the basis of the above descriptionTo make other changes in different forms. Here without also giving exhaustive to all embodiments. And thisThe apparent variation that belongs to connotation of the present invention a bit and extended out or variation still belong to protection scope of the present invention.
