Abstract

The utility model discloses a post insulator of an additional lead used for a rapid transit railway. The post insulator includes a porcelain insulator having an umbrella edge. An upper metal additional piece and a lower metal additional piece are fixed on an upper and a lower end of the porcelain insulator respectively. The lower metal additional piece includes a pedestal, a support fixed on the pedestal and connected to the lower end of the porcelain insulator. A plurality of installation holes are arranged in the pedestal uniformly. The post insulator of the additional lead used for the rapid transit railway has an advantage of high reliability when the additional lead is bonded, and the installation on a post top in a post form such as a reinforced concrete post, a steel post and the like or a frame of a centenary is simple, convenient, solid and reliable, thereby widening the installation range of the insulator in the utility model.

Description

A kind of used for high-speed railway additive wire post insulator

Technical field

The utility model relates to a kind of transmission of electricity product, is the insulator in a kind of high-speed electric railway contact line specifically.

Background technology

The safe operation of electrification railway contact net is to be achieved through use insulator on the return wire of additive wire, and insulator rises and supports and insulating effect.Additive wire return wire insulator mainly is pin insulator or suspension insulator or small-sized post insulator at present; Pin insulator need be fixed on the additive wire through wire rod or preformed wire clamp colligation; The poor reliability that insulator and additive wire link; Insulator belongs to can the puncture type, has certain potential safety hazard.Suspension insulator need be suspended on it on additive wire through baroque coupling; Because coupling complex structure; Insulator is installed needs the space bigger; Receive the restriction of catenary mast height and structure space easily, insulator also belongs to can the puncture type, also has certain potential safety hazard.Though small-sized post insulator overcomes the shortcoming of above-mentioned two kinds of insulators; But in high-speed railway and strong wind district railway contact line, because its stressed strong point has only one, and bending strength little (having only 4KN); When receiving wind-force; Cause the additive wire swing easily, therefore, the insulator of this mounting means is also unstable; Can not effectively play the effect of supports insulative and protection thunder and lightning, can not satisfy the requirement that high-speed electric railway and strong wind district electrification railway contact net are installed and used insulator.

The utility model content

Goal of the invention: in order to overcome the deficiency of prior art, the purpose of the utility model is the used for high-speed railway additive wire post insulator that provides a kind of colligation lead stable, firm, easy.

Technical scheme: for realizing above-mentioned technical problem; The technical scheme that the utility model adopts is: a kind of used for high-speed railway additive wire post insulator; Comprise the porcelain insulator that has full skirt; The two ends up and down of porcelain insulator are fixed with metal-ware and following metal-ware respectively, said time metal-ware comprise base, be fixed on the top of base and with the support of porcelain insulator lower ends, on said base, be provided with a plurality of equally distributed installing holes.

Said installing hole has 4.

It is more convenient, reliable for additive wire is installed; The said metal-ware that goes up comprises first annex that links to each other with the porcelain insulator upper end; On first annex, be connected with second annex; On said first annex, be provided with first groove, on second annex, be provided with second groove corresponding with first groove location and that opening is relative, said first groove forms about one perforations with second groove, two ends become the confession additive wire of horn mouth shape to pass through wire casing.

In order to improve the effect of clamping additive wire, said first groove and second groove are arc groove.

In order to strengthen the fastness of porcelain insulator and metal-ware company, said porcelain insulator is connected through binding agent with following metal-ware, last metal-ware.

Beneficial effect: compared with prior art, the utility model has the advantages that: reliable during the colligation additive wire, and and the capital of pillar forms such as contact line ferroconcrete prop or steel column or shoulder frame between simple installation, firmly, reliable; Thereby make that the fitting limit of insulator is wide.

Embodiment

Below in conjunction with accompanying drawing the utility model is done explanation further.

Extremely shown in Figure 5 like Fig. 1; A kind of used for high-speed railway additive wire post insulator; Comprise the porcelain insulator 1 that has full skirt; The two ends up and down of porcelain insulator 1 are connected with metal-ware and following metal-ware 2 respectively, wherein descend metal-ware 2 comprise base 21 and with support 22, the bottom of support 22 is fixedly mounted on the base 21, the upper end of support 22 links to each other through binding agent with porcelain insulator 1 lower end; On base 21, be provided with a plurality of equally distributed installing holes 23, preferred 4 and be evenly distributed on the base 21 of the quantity of installing hole 23; Last metal-ware comprises that first annex 3 and second annex, 4, the first annexes 3 link to each other through binding agent with porcelain insulator 1 upper end, and second annex 4 is located at the top of first annex 3 and fixing through bolt 5; On first annex 3, be provided with first groove 31; On second annex 4, be provided with second groove 41 corresponding with first groove, 31 positions and that opening is relative; First groove 31 and second groove 41 are arc groove, first groove 31 and second groove 41 wire casing that formation about one connects, two ends become the confession additive wire of horn mouth shape to pass through.

During installation; Bolt passed down on the capital or shoulder frame that is fixed on pillar forms such as contact line ferroconcrete prop or steel column behind 4 installing holes 23 on metal-ware 2 bases 21, so just realized being fixedly connected of the utility model used for high-speed railway additive wire post insulator and pillar.

Porcelain insulator 1 workmanship that is adopted in the utility model is good, and this insulator is puncture-proof, and insulation and protection thunder and lightning are effective.

The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
