Abstract
A bar-shaped porcelain insulator for an electrified railway contact network comprises a porcelain part, an upper steel cap and a lower steel cap. The upper steel cap and the lower steel cap are respectively fixed at the upper end and the lower end of the porcelain part via cement adhesive, spacers are respectively arranged between the upper steel cap and a contact end surface of the porcelain part and between the lower steel cap and a contact end surface of the porcelain part, the porcelain part adopting an umbrella skirt structure with excellent stain resistance is an impermeable solid porcelain body, and a fixing device for fastening end accessories is mounted on the upper steel cap. The appearance structure of the porcelain part of the insulator adopts advanced dirt-resistant umbrella skirt design so as to improve dirt resistance, the fixing device combined with the accessories is excellent in fastening performance, and the bar-shaped porcelain insulator greatly improves safety and reliability of running of Chinese electrified railway network.
Description
Technical field
The utility model relates to a kind of device used in the electrical network, is specially a kind of excellent type porcelain insulator that is applied on the contact nets in electrified railways.
Background technology
At present, China's electric railway total kilometrage is more and more, electrization rate also progressively improves, high voltage source a kind of power source that is absolutely necessary, especially build under the circuit environment in transformation of rail track raising speed by a large scale and new planning, the electric railway speed of service is greatly improved, and electrification railway contact net with the bar type porcelain insulator as play lead support, insulating effect on the line, at the important component that the contact line large tracts of land is used, this machinery to electric railway bar type porcelain insulator, electric property have also proposed requirements at the higher level.
The insulator of traditional structure only adopts bolt to connect the fixation steel plate of bottom, comes off easily when being given a shock, and causes insulator displacement itself, influences insulation property, even causes the paralysis of electric power system.
The utility model content
The technical problem that the utility model solved is to provide a kind of contact nets in electrified railways with excellent type porcelain insulator, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved realizes by the following technical solutions:
Contact nets in electrified railways are with excellent type porcelain insulator, comprise porcelain spare, last steel cap and following steel cap, the described steel cap of going up utilizes cement glue to be separately fixed at the two ends up and down of porcelain spare with following steel cap, last steel cap and following steel cap insert and put pad respectively with contacting of porcelain spare between the end face, the solid porcelain body that described porcelain spare adopts the good umbrella skirt construction of anti-pollution characteristic and can not puncture, described upward steel cap is equipped with the fixture of link department enclosure, the structure of fixture is: the U-bolt cover is clipped in the insulator end, adopt hex nut to reinforce, reinforcing place is provided with bullet pad and plain cushion and carries out anti-skiddingly, and pressing plate is set carries out fastening.
Beneficial effect: the utility model porcelain insulator spare contour structures adopts advanced full skirt resistant design, improved anti-pollution characteristic, the fastening function admirable of the fixture that combines with annex has improved the fail safe and the reliability of China's electrification railway contact net operation greatly.
