Abstract
A porcelain insulator of a rod-shaped support for contact networks comprises a porcelain piece, a lower accessory, concrete adhesive and a spacer, wherein the porcelain piece adopts an umbrella-skirt-shaped structure which has good anti-pollution performance and an un-penetrated solid porcelain body; the lower accessory adopts a steel-casting piece and the hot galvanizing is conducted on the surface thereof ; the porcelain piece and the lower accessory of the insulator are assembled into a product through the concrete adhesive; and the spacer is clamped between the lower end of the porcelain piece and the contact surface of the lower accessory. In the utility model, the stem diameter of a porcelain piece main body of the insulator is small, the utilization rate of material strength is high, the product structure is more reasonable, the appearance structure adopts the advanced design with the anti-pollution effect and in the umbrella-skirt shape, the insulator can be ensured to be used in various polluted areas, and the safety and the reliability of operation of electric railway contact networks in China are greatly improved.
Description
Technical field
The utility model relates to a kind of device used in the electrical network, is specially a kind of insulator that is applicable to that single-phase 25kV traction line insulation of filthy regional AC power frequency and fixing cord are used.
Background technology
At present, China's electrified railway total kilometrage is more and more, electrization rate also progressively improves, high tension supply a kind of propulsion source that is absolutely necessary, and the insulator that draws line insulation and fixing cord in the contact system also is widely used, the insulator of this conventional structure is often when connecting with the bottom fixation steel plate, adopt bolt to carry out fastening, the insulator of this structure is comparatively simple when mounted, but because there are vibrations in contact system electric wire itself, after using a period of time, the bottom captive nut tends to because of vibrations come off, and causes the insulator displacement, and common in addition insulator is stained easily under the environment in this filthy area of railway, can influence insulating power, cause the paralysis of electric power system.
The utility model content
The technical matters that the utility model solved is to provide a kind of contact system bar type pillar porcelain insulator, to solve the shortcoming in the above-mentioned background technology.
The technical matters that the utility model solved realizes by the following technical solutions:
Contact system bar type pillar porcelain insulator, comprise porcelain spare, following annex, cement glue and pad, the solid porcelain body that described porcelain spare adopts the good umbrella skirt construction of anti-pollution characteristic and can not puncture, described annex down is according to the machine-shaping of operating mode demand, adopt steel casting, surface heat is zinc-plated, and the porcelain spare of insulator adopts cement glue to be assembled into product with following annex, and pad is folded between the contact surface of porcelain spare lower end and following annex.
Beneficial effect: the utility model porcelain insulator spare main body bar footpath is little, strength of material degree of utilization height, it is reasonable that product structure more becomes, contour structures adopts advanced cluster parachute anti-pollution type design, guaranteed that such insulator is applicable to that different IAs uses, improved the safety and the reliability of China's electrification railway contact net operation greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1 contact system bar type pillar porcelain insulator, comprise porcelain spare 1, following annex 2, cement glue 3 and pad 4.
In the present embodiment, described porcelain spare 1 adopts the solid porcelain body that can not puncture, and adopts the umbrella skirt construction design, and this design not only anti-pollution characteristic is good, and porcelain spare main body bar footpath is little, strength of material degree of utilization height; Described annex 2 down is processed into the circular groove shape according to the operating mode demand, adopts steel casting, and surface heat is zinc-plated; Insert in the circular groove of following annex 2 the porcelain spare of insulator 1 lower end, and adopt cement glue 3 to be assembled into product, and pad 4 is folded between the contact surface of porcelain spare 1 lower end and following annex 2.
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
