Abstract
The invention discloses a cable clamp device capable of preventing joints from overheating. The cable clamp device is characterized by comprising a pair of cable clamps and a pair of O-shaped guide rings. Each of the cable clamps is provided with a flat connection end having connection fixing holes; the lower surface of one of the cable clamps is provided with a guide slot; and the upper surface of the other cable clamp is provided with a protrusion in clearance fit with the guide slot. The O-shaped guide rings sleeve the connection ends of the two cable clamps side by side and are provided with through holes corresponding to the connection fixing holes of the cable clamps. The O-shaped guide rings sleeve the connection ends of the cable clamps to expand contact areas of the joints, thereby bringing convenience for operators to do installation, facilitating heat dissipation and improving contact tightness; through the guide slot and the protrusion structures arranged on contact surfaces of the cable clamps, the contact area is expanded further, line faults caused by heating of the joints are eliminated, and running reliability of a power grid is improved.
Description
Technical field
The present invention relates to power domain, specifically a kind ofly eliminate the overheated wire clamp equipment of the end of a thread.
Background technology
This year, along with Regional Economic develops rapidly, people's material and cultural life quality progressively improves, power consumption obviously increases, and the requirement of the reliability of power supply is also significantly improved, for ensureing continuous reliable power supply, electrical network equipment for power transmission and distribution safe and reliable operation must be ensured, the continuous reliable power supply of guarantee Electricity customers.But electrical network equipment for power transmission and distribution quantity straight line rises, and equipment-patrolling and maintenance workload obviously increase; Because power load increases, equipment ampacity progressively strengthens, and at the number of stoppages of equipment connection weak link, also increases gradually; The defects such as equipment connection position production technology and construction quality, also reduce equipment reliability of operation.Find after deliberation, electric power transmission line joint area is overheated is a large principal element of line fault, and joint area is overheated mainly because wire clamp contact-making surface causes relatively not.
Summary of the invention
The weak point that the present invention exists to solve prior art, provide a kind of contact area large, the device clamp that screw is fixed and easy for installation, to eliminate the overheated problem of transmission line joint area.
Technical solution problem of the present invention adopts following technical scheme:
A kind ofly eliminate the overheated wire clamp equipment of joint, its design feature is, comprise a pair wire clamp and a pair O type guide ring, described wire clamp comprises the link that flat having is connected and fixed hole, wherein the link lower surface of a wire clamp is provided with guide groove, and the upper surface of another wire clamp is provided with the projection with guide groove matched in clearance; A pair described O type guide ring overlaps side by side and is pressed in outside two wire clamp links, and is provided with the through hole being connected and fixed hole corresponding to wire clamp.
Design feature of the present invention is also:
The cross section of described guide groove is for being greater than the arc surface of 1/2nd circles, and described projection is the spheroid matched with guide groove.
The cross section of described guide groove is inverted trapezoidal, and described longitudinal direction is match with guide groove trapezoidal.
Described guide groove is many, and described projection is identical with guide groove number.
Described guide groove and projection are horizontal or longitudinal.
Compared with the prior art, beneficial effect of the present invention is embodied in:
In order to increase junction contacts area, the present invention adopts a pair O type guide ring casing pressure, the installation of operating personnel easily, and advantageous heat dissipation, contact closely, and arranges guide groove and bulge-structure by wire clamp contact-making surface, also further increases contact area, eliminate the line fault caused because of wire clamp conductor joint heating, improve operation of power networks reliability.
Guide groove of the present invention adopts the arc surface or inverted trapezoidal that are greater than 1/2nd circles, and protruding adopt spheroid corresponding with it and trapezoidal time, wire clamp self can be allowed to carry out upper and lower locked location, according to horizontal guide groove and projection, then can horizontal locked location further, the bolt be arranged on wire clamp is not easily loosened, ensures the link fixing of wire clamp.
Accompanying drawing explanation
Fig. 1 is cable clamp structure schematic diagram of the present invention.
Fig. 2 is O type guide ring structural representation of the present invention.
Fig. 3 is wire clamp device assembles view of the present invention.
Fig. 4 is the A-A generalized section of Fig. 3.
Fig. 5 is the wire clamp cross sectional representation being provided with circular arc guide groove and spheroid projection.
Fig. 6 is the wire clamp cross sectional representation being provided with inverted trapezoidal guide groove and trapezoidal projection.
Number in the figure: 11, wire clamp one; 12, wire clamp two; 101,102 links, 1011 are connected and fixed hole, 1012 guide grooves, 1013 projections; 2, O type guide ring; 201, through hole.
By embodiment, explanation is further explained to technical solution of the present invention below in conjunction with accompanying drawing.
Embodiment
As shown in the figure, wire clamp equipment, comprise wire clamp 1, wire clamp 2 12, a pair O type guide ring 2, wire clamp comprises the link 101 that flat having is connected and fixed hole 1011, wherein the link lower surface of wire clamp one is provided with guide groove 1012, and the upper surface of wire clamp two is provided with the projection 1013 with guide groove matched in clearance; A pair described O type guide ring 2 side by side cover is pressed in outside two wire clamp links 101, and is provided with the through hole 201 being connected and fixed hole corresponding to wire clamp.
The cross section of described guide groove is for being greater than arc surface or the inverted trapezoidal of 1/2nd circles, and protruding is the spheroid or trapezoidal matched with guide groove, thus ensures that wire clamp one and wire clamp two can be located up and down by guide groove and projection.
During concrete enforcement, guide groove can be set to many, can be laterally or vertically arranges, and protruding identical with guide groove number, direction is corresponding with guide groove.
The connected mode of wire clamp equipment is: first a pair guide ring 2 on device clamp link place cover, then wire clamp one and wire clamp two is mated docking, is fixedly connected with two wire clamps finally by bolt through the hole that is connected and fixed on guide ring through hole and device clamp.
