High-voltage insulation gas circuit distributor for high-speed motor train unit

Abstract

The invention discloses a high-voltage insulation gas circuit distributor for a high-speed motor train unit. The high-voltage insulation gas circuit distributor comprises a distributor body, an upper-end connecting part, a lower-end connecting part, a gas channel core body and outer insulation umbrella groups, wherein the upper-end connecting part and the lower-end connecting part are arranged at the two ends of the distributor body; the outer insulation umbrella groups are distributed on the periphery end of the distributor and are integrally injection molded with the distributor body; the gas channel core body is arranged at the inner end of the distributor body; each of the port of the upper-end connecting part and the port of the lower-end connecting part is provided with a plurality of gas channels with trapezoidal sealing grooves which enable the gas channel core body to be in close fit with the gas channels of the upper-end and lower-end connecting parts, and enable the gas channels to communicate with the gas channel core body. The high-voltage insulation gas circuit distributor has the following characteristics that the sealing property is good; the distributor is capable of bearing the severe outdoor conditions, such as acute radiation of ultraviolet rays, salt mist, fine sand flying up in the air, high and low temperature change in the south and north areas and haze weather and has good anti-creepage trace, flame retardance and hydrophobicity; and the reliability and economy of the product can be ensured.

Description

technical field [0001] The invention relates to an airway combination part for pantograph lifting of high-speed train sets, in particular to a high-voltage insulating airway distributor for high-speed train sets. Background technique [0002] With the changes in the market demand for high-speed EMU railways, my country has continued to increase the construction of electrified railways, and dedicated passenger lines such as Chengdu-Chongqing, Lanzhou-Chongqing, Shanghai-Kunming, and Jinwen-Wenzhou have opened. Therefore, great efforts have been made to improve the safety of pantograph lifting for EMUs. In the past, pantographs relied on two air ducts for lifting operations. Now my country's climate conditions are extremely poor, such as strong ultraviolet radiation, salt fog, sand and dust, high and low temperature changes from north to south, and now A large number of cities have smoggy weather conditions, which can easily cause head-on creepage of air ducts, insulation flash...

Therefore, great efforts have been made to improve the safety of pantograph lifting for EMUs. In the past, pantographs relied on two air ducts for lifting operations. Now my country's climate conditions are extremely poor, such as strong ultraviolet radiation, salt fog, sand and dust, high and low temperature changes from north to south, and now A large number of cities have smoggy climate conditions, which can easily cause head-on creepage of air ducts, insulation flashover and other reasons to cause accident hazards, so it can no longer meet the normal and safe operation requirements of high-speed rail
