Description
Technical field
The present invention relates to high tension insulator, belong to the porcelain insulator field of using in the urban track traffic subway contact line, specifically relate to a kind of urban track traffic subway and use rigid suspended porcelain insulator.
Background technology
More and more along with China's one line, tier 2 cities resident population, the inconvenience of the crowded and life of traffic has belonged to the cardinal task of national economy.Solve the urban traffic congestion, development urban light rail subway has become local urban government leader's high workload agenda.The urban light rail subway is all taked in existing a line, tier 2 cities and coastal cities, little by little improves urban traffic environment.
At present; China's urban light rail subway existing employed " the rigid suspended pin insulator of 1.5kV " because intrinsic product structure form is unreasonable, employing be that " interior mucilage binding " structure connects; As shown in Figure 1; The following problem of ubiquity in the use: 1, because the expanded by heating coefficient of metal-ware is far longer than the expanded by heating coefficient of insulator porcelain body, metal-ware is under the operational environment of low-voltage, big electric current, behind the expanded by heating and produce lateral expansion power; This expansive force is that the compression of porcelain body only can not offset, thereby causes this " rigid suspended pin insulator " that the porcelain body explosion takes place; 2, the mechanical technique performance index of product are on the low side, and margin of safety is little, and quality is dispersed big, can not satisfy the safe operation needs of existing locomotive, have bursting accident to take place repeatly; 3, the last annex of product is a bolt, and when carrying out mucilage binding in the upper surface of porcelain body with cement glue, it is vertical to be difficult to mucilage binding, causes bolt under tension, produces the effect of bending force again, and the influence of power by bending causes one side of porcelain body that explosion takes place.4, the configuration design creepage distance of product is not enough, and the magnitude of voltage of anti-corona is low, and the withstand voltage value under the close filth of geavy salt is low, and anti-pollution characteristic is relatively poor, is prone to flashover, is prone to puncture; 5, the porcelain spare of product body interior, solid distance is short, under the two ends cement glue makes moist situation for a long time, is prone to flashover and punctures.All drawbacks of above-mentioned five kinds of design defect cause the safe operation on schedule of subway light rail train.
Summary of the invention
The object of the invention is exactly to above-mentioned shortcoming; Propose that a kind of antiknock is split, mechanical strength is high, creepage distance is big, anti-pollution characteristic good; Meet and be difficult for flashover, the difficult puncture under heavy fog, thunder and lightning, heavy rain, the shoe ice condition condition; Anti-corona voltage value is high, and the withstand voltage value is high under the close filth of geavy salt, and self-cleaning ability is strong, a kind of new city light rail subway that can exchange use is with the rigid suspended porcelain insulator of 1.5kV.
The technical scheme that the present invention adopted: a kind of urban track traffic subway is used rigid suspended porcelain insulator; It contains metal-ware, following metal-ware and insulator porcelain body; It is characterized in that: described gluey position of going up metal-ware and following metal-ware be have the bottom surface, be columnar groove on every side; Described outer end of going up metal-ware is protruding with screw rod; The mucilage binding face center of described down metal-ware is convex screw cylinder, and the mucilage binding position of described insulator porcelain body has through sintering process and the porcelain sand of strong bonded, and the insulator porcelain body is with last metal-ware, metal-ware becomes integral body through outer mucilage binding mode mucilage binding down.
Further say: described insulator porcelain body only is provided with a full skirt.
Further say: described full skirt is the bell-jar full skirt.Described bell-jar full skirt is meant that the neighboring of full skirt has the structure of stretching out downwards.
Further say: the umbrella concave surface of described full skirt is provided with a circle or encloses dark umbrella rib structure more.
Further say: the said screw rod height of going up metal-ware is that 55 millimeters, bar directly are the M16 millimeter; The said screwhole diameter of metal-ware down is the M16 millimeter.
Further say: described insulator total height is 155 ± 3 millimeters, and actual use effective depth is 100 ± 3 millimeters.
The invention has the beneficial effects as follows:
1, described gluey position of going up metal-ware and following metal-ware is a groove; The mucilage binding position of insulator porcelain body has through sintering process and the porcelain sand of strong bonded; Insulator porcelain body and last metal-ware adopt outer mucilage binding mode; Adopt inside and outside associating mucilage binding mode mucilage binding to become whole with following metal-ware; The combination of the inside and outside associating mucilage binding of this employing, integral body have improved the counter-bending mechanical performance of product, have also avoided because of the inconsistent explosion phenomenon that causes of the coefficient of expansion of metal-ware and porcelain spare body simultaneously; Simultaneously, also increased the solid distance of porcelain spare body interior, avoided causing the puncture explosion phenomenon at this position because of the flashover that makes moist that interior mucilage binding causes;
2, described metal-ware and the outer mucilage binding mode of insulator porcelain body employing of going up; Be difficult for eccentric when having determined installation; Avoided causing metal-ware or following metal-ware under tension because of the installed part out of plumb; Produce the destruction of bending force again, make the phenomenon of one side porcelain body generation explosion of power by bending;
3, insulator porcelain body umbrella concave surface that bell-jar full skirt, full skirt be set is provided with a circle or encloses dark umbrella rib structure more; Have damp proof sudden strain of a muscle, anti-pollution flashover, advantage that the dirty ability of anti-soil is stronger; Increased creepage distance effectively, brought up to more than 270 mm by 250 original mm;
4, the size restrictions of insulator is best technical scheme, has interchangeability with existing insulator simultaneously.
Urban light rail subway of the present invention is with the rigid suspended insulator of 1.5kV, and its cold and hot cracking temperature approach is up to 100 ℃.
