Abstract
The utility model discloses a device for fixing a composite-insulator core rod of an overhead transmission line, and the device comprises a connection sleeve. The interior of the connection sleeve is provided with a composite-insulator core-rod position-fixing finger. The inner wall of the upper end of the connection sleeve is provided with two fastening slopes which are respectively in an arc-shaped structure, wherein each structure becomes thick from one end to the other end. The device provided by the utility model is simple in structure, and is easy to install. The composite-insulator core rod clamping bar can be firmly pressed on a composite-insulator core rod, thereby effectively preventing the severe accident that a wire falls to the ground, and adverse effects, wherein the accident and the adverse effects are all caused by the brittle break of the composite-insulator core rod.
Description
Technical field
The utility model relates to insulator jockey, is specifically related to a kind of overhead power transmission line composite insulator plug fixture.
Background technology
That composite insulator has is lightweight, good antifouling effect and the advantage such as operation maintenance workload is few, in the construction of electrical network with in servicely obtain a large amount of uses.But along with the sharp increase of composite insulator usage quantity, its fault and rate of failure also mouth become to increasing, especially composite electric insulator core bar Fragile Split, though probability of happening is little, consequence is serious, even may cause the generation of electrical network serious accident.
In order to address the above problem, number of patent application is that CN201210086116.2 discloses a kind of built on stilts electric power transmission line compound inslation sub-connecting device, this apparatus structure is more complicated, installation process is more loaded down with trivial details, in specific experiment process, find that in its taper, wedge pipe, owing to shrinking, can not be fixed meeting core rod of insulator.
Utility model content
For compound inslation sub-connecting device in prior art, this apparatus structure is more complicated, the problem that installation process is more loaded down with trivial details, and the utility model provides a kind of overhead power transmission line composite insulator plug fixture simple in structure.
To achieve these goals, the technical solution adopted in the utility model is: a kind of overhead power transmission line composite insulator plug fixture, comprise branch sleeve, in branch sleeve, establish composite electric insulator core bar retention finger, the upper end inwall of branch sleeve is provided with two fastening inclined-planes, and described fastening inclined-plane is by the arcuate structure that is thinned to thick gradual change.
The index of described retention finger is one of in 2,3,4,5.
Described retention finger is and fixes circular-arc that composite electric insulator core bar coordinates.
The finger of described finger-like conical external screw thread pipe be with coordinate with plug circular-arc.
Beneficial effect is: the utility model is simple in structure, installs simple and easyly, and plug clamping strip can firmly be pressed on core rod of insulator, can effectively prevent that wire because causing after composite electric insulator core bar brittle failure such as lands at serious accident and the dysgenic generation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cross section structure schematic diagram of the present utility model.
Embodiment
As depicted in figs. 1 and 2, a kind of overhead power transmission line composite insulator plug fixture, a kind of overhead power transmission line composite insulator plug fixture, comprise branch sleeve 2, in branch sleeve 2, establish composite electric insulator core bar retention finger 4, the upper end inwall of branch sleeve 2 is provided with two fastening inclined-planes 3, and described fastening inclined-plane 3 is by the arcuate structure that is thinned to thick gradual change.The index of retention finger 4 is one of in 2,3,4,5.Retention finger 4 is circular-arc for what coordinate with fixing composite electric insulator core bar 1.Retention finger 4 is pressed on plug, branch sleeve 2 is set in the retention finger 4 of composite electric insulator core bar 1, when composite electric insulator core bar retention finger passes in the middle of thin two fastening inclined-planes 3, then in heavy wall place rotary course, retention finger 4 composite electric insulator core bar 1 that is fixedly clamped.
