Description
Technical field
The utility model relates to electrified railway technical field, is specifically related to a track traffic discrepancy section line section insulator.
Background technology
In prior art, a track traffic parking area discrepancy section line all adopts rigid suspension OCS, because the section line section insulator two ends of coming in and going out are powered by parking area and main track Liang Ge substation respectively, so there is voltage difference.When subway train pantograph is passed through section insulator, may, by the slide plate short circuit on section insulator both sides, make the power supply area conducting of parking area and main track, the voltage difference of generation causes slide plate burn, and serious meeting causes catenary cut off fault.
Utility model content
The purpose of this utility model is to provide an a kind of track traffic discrepancy section line section insulator, can reduce broken string risk, reduces arcing phenomenon and can effectively control traction substation tripping operation, the safe operation of guarantee track traffic.
In order to achieve the above object, the utility model is achieved through the following technical solutions: a track traffic discrepancy section line section insulator, be characterized in, and comprise two terminal clamps, insulating bar, slide plate, main chord frame, the first longitudinal support and the second longitudinal support;
The both sides of two above-mentioned terminal clamps are respectively equipped with a slide plate;
Between above-mentioned terminal clamp and slide plate, leave a segment distance;
Between above-mentioned terminal clamp and slide plate, be connected by main chord frame;
Between two above-mentioned terminal clamps, be provided with insulating bar;
One end of above-mentioned insulating bar connects the middle part of the first longitudinal support, and its other end connects the middle part of the second longitudinal support;
Above-mentioned slide plate is symmetrical arranged, and is provided with between any two gap;
The first above-mentioned longitudinal support and the two ends of the second longitudinal support are connected with the middle part of two slide plates that are positioned at homonymy terminal clamp respectively.
The two ends of above-mentioned insulating bar are provided with stepped shaft.
The end of the slide plate between two above-mentioned terminal clamps is provided with insulation cut-off point,
The other end of above-mentioned slide plate is made up of the transition phase of multistage arc shear.
Above-mentioned section insulator also comprises auxiliary wire clamp;
Above-mentioned two slide plates that are positioned at terminal clamp homonymy connect by auxiliary wire clamp.
The utility model track traffic section line section insulator of coming in and going out compared with prior art has the following advantages: because slide plate end has adopted the transition phase of multi-radian shear, guaranteed the smooth-going incision of subway train pantograph and skidded off, avoided arcing and shock; Because slide plate is arranged symmetrically with, after assembling, make it form one and without electric spacer region, vehicle field is separated completely with circulation line, pantograph can trans-regionally not flowed; Because insulating bar is provided with stepped shaft, insulating bar can rotate, when high-abrasive material may wear to a certain degree, can be rotated an angle, a new contact surface is provided, and this can extend the service life of whole insulating bar so to greatest extent, and adjust time convenient, fast.
