Problems solved by technology

However, this scheme does not take into account the self-cleaning function of the segmented insulator for dirt deposition, especially the deposition of conductive particles generated by brush friction in the channel, which will bring the risk of losing the segmented insulation function to the segmented insulator; In addition, this scheme does not take into account that long-term wear will cause a height difference between the contact surface of the segmented insulator and the current delivery surface of the contact rail, and this height difference will cause the brush to be impacted there

Embodiment Construction

[0015] Figure 1 to Figure 3 It shows a side current receiving section insulator described in this application, which includes an insulating body (1), a shed (2), and the shed (2) is arranged on the insulating body (1) and slides along the brush Direction distribution, the edge of the shed (2) is chamfered, the insulating body (1) has a side surface (1a), a top surface (1b), and the acute angle (α, β) between it and the friction surface (2a) They are 0 figure 2 shown).

[0016] The surface of the section insulator is made of hydrophobic wear-resistant material, or further its whole is made of hydrophobic wear-resistant insulating material. The slope / arc surface set in the scheme, combined with its surface hydrophobicity, can effectively inhibit the deposition of dirt on the surface of the segmental insulator under the action of the external environment (vibration, rain, etc.), which is conducive to reducing the daily maintenance workload.

Abstract

The invention relates to a lateral current collection section insulator. The lateral current collection section insulator comprises at least an insulation main body and an umbrella skirt, the umbrellaskirt is arranged on the insulation main body, and distributed along the sliding direction of an electric brush, the insulation main body has an inclined surface, and is combined with the hydrophobicproperty of the surface, and the fouling deposit on the surface of the section insulator can be efficiently suppressed. The section insulator matched with a fastened part is mounted on a contact railthrough gaskets, in daily maintenance, the height difference between the current collection surface and the insulator caused by long-term wear by changing the number of the gaskets can be compensated, and the whole section insulator does not need to be replaced.

Description

technical field [0001] The present application relates to a side current receiving section insulator for a busbar system. Background technique [0002] In the field of rail transit, some standard vehicles use the contact rail system to provide power for the vehicles, and the vehicles are supplied with current through the brushes. In actual operation, since the electrification of the line is designed as a combination of multiple electrical segments, the electrical segments need to be insulated and connected through segmental insulators. In the article "Urban Rail Transit Contact Rail Segment Setting Method and Improvement Suggestions" published in the journal "Railway Standard Design" in the 06th issue of 2014, a segmented insulator used in the high-speed maglev contact rail system is disclosed. Its structure The design is closely combined with the section size of the steel-aluminum composite rail, which can not only meet the installation conditions of the embedded segmental...
