Abstract
The utility model relates to a novel composite insulator testing connecting part. The novel composite insulator testing connecting part mainly comprises two insulators and a connecting part, wherein connecting components are sheathed at the connected ends of the two insulators respectively, and two ends of the connecting component are respectively provided with through holes through which fixing nuts pass; the connecting part mainly comprises a connecting part main body and two connecting part segments, the two connecting part segments are distributed at two ends of the connecting part main body, the connecting part segments and the connecting part main body are both rectangular, a through hole through which a fixing nut passes is formed in each connecting part segment and corresponds to the through hole in the connecting component, and the two connecting part segments are arranged at two sides of the connecting part respectively and are fixed by the fixing nut. The novel composite insulator testing connecting part has the advantages that the phenomena that the connecting structure of a grounding terminal of the composite insulator is deformed after mechanical strength test is carried out, the mechanical strength test is instable and the stress is uneven are avoided.
Description
Technical field
The utility model relates to a kind of novel composite insulator test web member, a kind ofly specifically can prevent the distortion of insulator earth terminal syndeton and stressed uniform device in process of the test.
Background technology
Composite insulator is a kind of special insulation control, can in overhead transmission line, play an important role.In one's early years, insulator is used for electric pole, along with scientific and technological development, slowly develops in one end of high type high-tension bus-bar connection tower and has hung the insulator of a lot of plate-likes, and it,, in order to increase creepage distance, is made by glass or pottery conventionally, is just insulator.Insulator plays two basic roles in overhead transmission line, be support wire and prevent electric current return ground, these two effects must be guaranteed, insulator should be because environment and electric load the condition various and electric stress causing that changes lost efficacy, otherwise insulator just can not produce great effect, will damage use and the operation life of whole piece circuit.
At present, in the prior art, for the connection between two adjacent composite insulators, the hard jumper composite insulator test of existing this kind of structure connected mode is: adopt two insulator earth terminal web member docking, with set bolt, be connected in series, then carry out the mechanical robustness testing of product.Adopt such structure may cause the malformation of two insulator earth terminals in process of the test, directly will after two web member docking, owing to being connected in series bolt length, cause for a moment mechanical robustness testing unstable, stressed inconsistent phenomenon.
Utility model content
The technical problems to be solved in the utility model is to provide and a kind ofly can prevents the distortion of in process of the test insulator earth terminal syndeton and stressed uniformly novel composite insulator test web member.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of novel composite insulator test web member, and its innovative point is: mainly comprise insulator and web member;
Described insulator has two, is respectively insulator A and insulator B, and the one end being connected at insulator A and insulator B is respectively installed with link, and described link integral body is Ω shape, has hold the through hole that hold-down nut passes at the two ends of link;
Described web member mainly comprises connector main body portion and web member branch, described web member branch one has two, be distributed in the two ends of connector main body portion, web member branch and connector main body portion be rectangular shape all, described web member integral body is crosswise, in web member branch, have and hold the through hole that hold-down nut passes, and this through hole is corresponding with the through hole on link;
Described insulator A and insulator B lay respectively at the both sides of web member, and with nut, fix after passing the through hole of opening on insulator A, web member and insulator B successively by hold-down nut.
The utility model has the advantage of: after the web member connection by design machine-shaping, carry out mechanical robustness testing, can avoid due to the composite insulator earth terminal syndeton distortion of carrying out causing after mechanical robustness testing, with directly by after two web members docking because the differ mechanical robustness testing that causes of serial connection bolt length is unstable, stressed inconsistent phenomenon, has guaranteed that the consistance of the reliability of this connected mode in the circuit construction and installation process and product quality is stable better.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of Novel combined insulator test web member of the present utility model.
Embodiment
Schematic diagram is as shown in Figure 1 known, and Novel combined insulator test web member of the present utility model mainly comprises insulator and web member.
Insulator one has two, be respectively insulator A1 and insulator B4, at insulator A1, near one end of insulator B4, be connected with link A2, at insulator B4, near one end of insulator A1, be connected with link B3, link A2 and link B3 integral body are Ω shape, have hold the through hole that hold-down nut 5 passes at the two ends of link A2 and link B3.
Web member mainly comprises connector main body portion 7 and web member branch 8, web member branch 8 one has two, be symmetrically distributed in the two ends of connector main body portion 7, the xsect of web member branch 8 and connector main body portion 7 is rectangular shape all, web member integral body is crosswise, in Liang Ge web member branch 7, all have the through hole that an appearance hold-down nut 5 passes, and the position of this through hole is corresponding with the position of the through hole of opening on link A2 and link B3.
When insulator A1 and insulator B4 are connected by web member, by insulator A1 and insulator B4 symmetrical both sides that are placed in web member respectively, then, by a hold-down nut 5, pass successively the through hole of opening on insulator A1, web member branch 8 and insulator B4, after passing again, by set nut 6, be fixed.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and instructions, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
