Description
Technical field
This utility model relates to a kind of anti-fouling type neutral section insulator, in particular to a kind of anti-fouling type neutral section insulator at the contact line out-phase electricity segmentation of single-phase 50Hz, 25kV attached wires of AC electrified railway.
Background technology
At present, the domestic section insulator used on electric railway contact line has rhombus section insulator, and its structure one symmetrical rhombus of composition will not occur drill bow.But the insulating slide of this section insulator is by carbon slipper and scribbles the pantograph pan of lubricating oil and pollutes, cause the easy scaling loss of section insulator, the most this section insulator stress is the most on the same axis, under by state of tension, produce moment of flexure, causing and be bent downwardly in the middle part of section insulator, produce hard spot, domestic neutral section insulator there is also the problems referred to above.
Utility model content
The purpose of this utility model is the problem above overcoming prior art to exist, it is provided that a kind of anti-fouling type neutral section insulator.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is achieved through the following technical solutions:
A kind of anti-fouling type neutral section insulator, insulator including two silicone rubber composites setting up and down, described insulator two ends connect anchor head, anchor head lateral symmetry is provided with metal runners, described metal runners one end is provided with the starting rod bent obliquely upward, between adjacent two starting rods, extinguishing arc horn gap is not less than 330mm, and the insulator both sides of described lower section are connected by insulating slide bracket insulating slide.
Further, described anchor head is connected with the line that contacts of lower section by parallel groove clamp.
Further, described parallel groove clamp being provided with dropper and supports, described dropper is supported and is connected with the line that contacts of top by trimming bolt, dropper line.
The beneficial effects of the utility model are:
1. this anti-fouling type neutral section insulator major insulation uses silicon rubber compound insulator, in the sub-both sides of major insulation equipped with supplementary insulation slideway, guarantee that major insulation silicon rubber compound insulator and block of bow collector of electric locomotive are non-immediate sliding contact, prevent major insulation from polluting and causing insulation breakdown scaling loss.
There is under the working tension of 2.10-30kN good reliability and stability.
3. good insulation preformance, creep distance ＞ 1800mm, durability against pollution is strong, at 0.35mg/cm2(equivalent salt deposit density) and 0.2 mg/cm2In the case of (ash), dirty proof voltage is more than 40kV, it is adaptable to Chong Wu district.
4. air insulation clearance is big, and air insulation clearance >=330mm meets the requirement of TB/T3037--2002 " 25KV contact nets in electrified railways neutral section insulator ".
5. service life is long.Major insulation silicon rubber compound insulator and pantograph are non-immediate sliding contact, and metal runners, insulation auxiliary slide channel, at same plane, without hard spot, wear away low, extend service life, and this anti-fouling type neutral section insulator is in the condition of normal use no less than 15 years.
6. install, easy to adjust.Owing to anti-fouling type neutral section insulator entirety has carried out comprehensive adjustment and solidification in factory, thus avoiding assembling at the scene the difficulty of adjustment, on-the-spot need to adjust level (parallel with rail level) and negative degree of speeding by messenger wire.
The most lightweight, symmetrical, mounting and adjusting uses negative degree of speeding, and makes contact pressure more uniform, it is to avoid hard spot, meets the needs that bullet train runs.
8. Negotiation speed is high, opposing traffic, whole anti-fouling type neutral section insulator is formed working face with the contact surface of motorcycle pantograph by metal runners and supplementary insulation slideway, and contact line is connected excess smoothness with anti-fouling type neutral section insulator, without hard spot when making block of bow collector of electric locomotive pass through, do not make bow.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing describe in detail as after.Detailed description of the invention of the present utility model is shown in detail in by following example and accompanying drawing thereof.
