Abstract
The utility model relates to a high-speed electric rail traction vehicle top composite insulator which comprises a column body, an upper installation base, a lower installation base, a shed, an upper insert and a lower insert; the cylindrical column body is provided with seven umbrellas, the upper installation base and the lower installation base; the column body, the shed and the lower center of the column body are provided with conical inner holes; and the upper installation base and the lower installation base are square. The high-speed electric rail traction vehicle top composite insulator not only has higher strength and rigidity, but also has good surface and overall hydrophobicity, and has far higher capability for resisting wind, sand and the damage of harmful substances when a vehicle runs at high speed. The creepage distance and flashover distance are more than or equal to 1100mm, thereby reducing the possibility that the shed is bridged by the icicle and water and enhancing the self-cleaning capability of the insulator. The installation stress is good and an installation bolt directly forces on the metal inserts, thereby reducing the possibility of damage of long and intense vibration when the insulator is installed and works.
Description
Technical field
The utility model relates to the insulation of high-speed power track drawing vehicle, particularly high-speed power track drawing vehicle roof high voltage isolator and bus support insulator.
Background technology
The used roof insulator of present high-speed power track drawing vehicle mostly is material of main part with silicon rubber, and silicon rubber has good insulation property, hydrophobic performance and high-and low-temperature resistance performance, is the ideal material of manufacturing the outdoor insulative product.But significantly raising along with the railway speed of a motor vehicle, silicon rubber insulator can produce fierce trembling having held vibration suffered when can't stand towing vehicle at high-speed cruising aspect the strength and stiffness and impacted full skirt, thereby the fatigue aging and the damage of full skirt root have been produced, the cycle of operation that adds high-speed railway is long, factors such as the wide and traffic coverage air quality in operation area is not good can be that the insulator of material of main part causes great damage to silicon rubber also.Therefore the roof insulator of high-speed track towing vehicle not only will have has good tolerance performance to the corrosion of overvoltage, high temperature, low temperature, salt fog, icing, heavily contaminated and harmful substance etc., also must have very high mechanical strength simultaneously, impact, the wear-out failure of various suspended particles in fierceness vibration that rigidity and rational structure are produced when the high-speed cruising with opposing and the running environment.Chinese patent 02283253X has announced a kind of electric locomotive roof supporting insulator, and it is pagoda shape, full skirt structure, and force-bearing situation is poor, creepage distance is little but this patent is installed.
The purpose of this utility model is intended to for high-speed power track drawing vehicle provides a kind of simple in structure, easy for installation, and insulation property are good, high-and low-temperature resistance and the good high-speed power track drawing vehicle roof composite insulator of whole hydrophobic performance.
The technical solution of the utility model comprises: cylinder, last mount pad, full skirt, following mount pad and upper and lower inserts, it is characterized in that: described cylinder is a truncated cone-shaped, which is provided with 7 umbrellas and upper and lower mount pad, cylinder, full skirt, the as a whole structure of mount pad up and down; The lower central of described cylinder is provided with tapered bore, and the head of this endoporus is a hemisphere; The diameter of described full skirt is respectively from top to bottom: the 1st umbrella and the 7th umbrella are maximum and identical, and the 3rd umbrella is identical with 5 umbrellas and be intermediate diameters; 2nd, 4,6 umbrella diameters are minimum and identical; Described upper and lower mount pad is square, and the last mount pad length of side is less than the length of side of following mount pad.
Described upper and lower inserts is a metal material, is embedded in the upper and lower mount pad, and the height of following inserts is greater than the thickness of following mount pad.
The intensity of the roof insulator of the existing high-speed track towing vehicle of the utility model is big, has improved greatly that the anti-impact of insulator in high-speed cruising is moving, the ability of anti-vibration and anti-load.
Adopt full skirt of the present utility model, increased creepage distance and flashover distance, creepage distance 〉=1100mm; Reduce full skirt by the probability of icicle and water bridge joint, also strengthened the self-cleaning ability of insulator simultaneously.
Improved the installation force-bearing situation of insulator, construction bolt directly forces on the metal insert, has reduced insulator and produce the damaged probability of long fierceness vibration when installation and operation.
Insulator not only has higher intensity and rigidity, has also had surface of good and whole hydrophobic performance simultaneously, and the ability that opposing wind sand and harmful substance are damaged in the vehicle high-speed cruising is greatly improved.
