Abstract
The utility model relates to a section insulator used on the contact net of the electrified railway, mainly solve the problem that the suspension cable at its both ends is easy to be loosened, easy to be conducted and easy to be burnt, characterized in that, three insulating rods are arranged in the shape of an inverted triangle, two connecting pieces are fixed at its both ends respectively, the other both ends of two connecting pieces are connected with the contact wire of the adjacent section respectively, the two sides of each connecting piece are fixed with metal slideways respectively, and form an arc extinguishing angle separately, the length of the metal slideways is unequal, the long metal slideways at both sides are intercrossed on the plane, each side of the lower insulating rod is provided with an insulating slideway, the contact wires at both ends of the two connecting pieces are provided with suspension cables, and the two ends of the suspension cables are insulators.
Description
The utility model relates to a kind of section insulator, particularly relates to the section insulator that uses on a kind of electrification railway contact net.
In prior art, the section insulator that uses on the electrification railway contact net is made up of insulating rod, metal runners and connector, and it is simple in structure, but its rigidity deficiency is lax easily; Its dirty back of surface knot is conduction easily; The suspension cable at its two ends is burnt etc. easily.
The purpose of this utility model provides a kind of lax, easy conductive and suspension cable section insulator that can not burn not that is difficult for.
The utility model is by insulating rod, metal runners and connector are formed, it is characterized in that: three insulating rods are del and arrange, its two ends two connectors respectively fix, the two ends in addition of two connectors are connected with the contact wire of adjacent segment respectively, both sides at each connector are fixed with metal runners respectively, it outwards forms the oblique angle by the end mutually to the centre, its the inner replication that makes progress, and be separated from each other and form an arcing horn, the length of metal runners is unequal, one is long and the other is short for every side, the both sides of each connector also are that one is long and the other is short, the long metal runners in both sides is intersected in the plane mutually, respectively adorn an insulation slideway in each side of bottom insulating rod, the lower surface and the metal runners lower surface of insulation slideway are on the same horizontal plane, lay suspension cable in the contact wire at two connector two ends, and the two ends of suspension cable are insulator.
Because the utility model is made up of insulating rod, metal runners and connector, three insulating rods are del to be arranged, so it is difficult for relaxing; Its two ends two connectors respectively fix, the two ends in addition of two connectors are connected with the contact wire of adjacent segment respectively, both sides at each connector are fixed with metal runners respectively, it outwards forms the oblique angle by the end mutually to the centre, its the inner replication that makes progress, and be separated from each other and form an arcing horn, the length of metal runners is unequal, one is long and the other is short for every side, and the both sides of each connector also are that one is long and the other is short, and the long metal runners in both sides is intersected in the plane mutually, respectively adorn an insulation slideway in each side of bottom insulating rod, the lower surface and the metal runners lower surface of insulation slideway are on the same horizontal plane, so it can not hit bow, and also easy conductive not; Lay suspension cable in the contact wire at two connector two ends, the two ends of suspension cable are insulator, so its suspension cable can not burnt.
Below in conjunction with accompanying drawing the utility model is elaborated,
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the end view of Fig. 1,
Three insulating rods 1 are del and arrange, in order to guarantee after its surface knot dirt not easy conductive, the creep distance of insulating rod is greater than 1600mm, its two ends are two connectors 2 respectively, 3 fix, the in addition two ends of two connectors respectively with the contact wire 4 of adjacent segment, 5 are connected, both sides at each connector are fixed with metal runners 6 respectively, 7,8,9, it outwards forms the oblique angle by the end mutually to the centre, its the inner replication that makes progress, and be separated from each other and form an arcing horn, the length of metal runners is unequal, one is long and the other is short for every side, the both sides of each connector also are that one is long and the other is short, the metal runners 6 that both sides are long, 8 intersect in the plane mutually, respectively adorn an insulation slideway 10 in each side of bottom insulating rod, 11, the lower surface and the metal runners lower surface of insulation slideway are on the same horizontal plane, in the contact wire at two connector two ends, lay suspension cable 12,13, the two ends of suspension cable are insulator.
Claims (2)
1, a kind of section insulator, comprise insulating rod, metal runners and connector, it is characterized in that: three insulating rods are del and arrange, its two ends two connectors respectively fix, the two ends in addition of two connectors are connected with the contact wire of adjacent segment respectively, both sides at each connector are fixed with metal runners respectively, it outwards forms the oblique angle by the end mutually to the centre, its the inner replication that makes progress, and be separated from each other and form an arcing horn, the length of metal runners is unequal, one is long and the other is short for every side, the both sides of each connector also are that one is long and the other is short, the long metal runners in both sides is intersected in the plane mutually, respectively adorns an insulation slideway in each side of bottom insulating rod, and the lower surface and the metal runners lower surface of insulation slideway are on the same horizontal plane, lay suspension cable in the contact wire at two connector two ends, the two ends of suspension cable are insulator.
