Abstract
The utility model relates to the field of electrified railway overhead line systems, in particular to a direct-current overhead line system insulating straight cantilever which comprises a cantilever body, pulling bars, handle pipes, insulator chains and contact hanging components. The direct-current overhead line system insulating straight cantilever is characterized in that the insulator chains are arranged close to one side of a supporting column and are arranged between the pulling bars and the supporting column and between the cantilever body and the supporting column respectively, and the cantilever body, the pulling bars and the contact hanging components are located on equipotential. The cantilever body is formed by cutting off a circular steel tube, and the insulator chains are composite insulators. Compared with the prior art, the direct-current overhead line system insulating straight cantilever has the advantages that the cantilever body is formed by cutting off a circular steel tube and is light and simple in structure and convenient to construct, mount and repair; the insulator chains can not be easily polluted by smoke in a mixed traction section, and the electrical insulation strength of the contact hanging components is improved; the cantilever body, the pulling bars and the contact hanging components are located on equipotential, electrified maintenance operation is greatly facilitated, power-off maintenance frequency is reduced, and the development tendency of overhead line system devices is met.
Description
Technical field
The utility model relates to electrification railway contact net field, relates in particular to a kind of direct current contact system straight bracket that insulate.
Background technology
Bracket is a kind of supportive device of contact net equipment, is arranged on pillar, and main application is to support contact suspension assembly.Straight bracket can only be set up pillar in railway one side when being subject to landform restriction, and needs to hang 2～3 groups of contact suspension assemblies herein.Many employings is nonisulated straight bracket at present, and its version is: contact suspension assembly (6) is suspended in the flat head section of handle pipe (5) front end by insulator chain (1), bracket (2) root and lacing wire (3) are directly installed on pillar (4).Bracket (2) is to be made by angle steel, and materials are many, structure is heavy, higher to pillar capacity requirement, installation and maintenance difficulty, and insulator chain (1), directly over circuit, easily pollutes simultaneously, has increased safety hazard.The shortcoming of this nonisulated bracket maximum is to be unfavorable for carrying out carrying out of power-on serving operation, in work in the past, because contact system circuit is subject to influence of temperature change larger, contact suspension assembly is elongated or shortened by influence of temperature change, makes bracket (2) skew or handle pipe (5) skew.In order to improve the mode of operation of contact wire, often to adjust the deviant of handle pipe and bracket, if adjust or change the handle pipe (5) of nonisulated bracket below, just must apply for interruption maintenance, and application interruption maintenance has just been upset the order of Transportation Organization, for transportation, protect product work and manufactured trouble.In addition, meet transportation production work more nervous time, to power off time, do not process hidden danger, make the operation of equipment belt hidden danger, caused transportation to protect the passive situation that product work can not get Reliable guarantee.
Summary of the invention
The purpose of this utility model is to provide a kind of direct current contact system straight bracket that insulate, and makes bracket and lacing wire and contact suspension assembly in same equipotential, and insulator is difficult for being polluted by sootiness, facilitates carrying out of hotline maintenance operation simultaneously.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of direct current contact system straight bracket that insulate, comprise bracket, lacing wire, handle pipe, insulator chain and contact suspension assembly, described insulator chain arranges by pillar side, is separately positioned between lacing wire and pillar, between bracket and pillar, and bracket, lacing wire and contact suspension assembly are in same equipotential.
Described bracket is cut into by round steel pipe.
Described insulator chain is compound insulator.
Compared with prior art, the beneficial effects of the utility model are:
1) bracket adopts round steel pipe to make, and has structure lightly simple, technological performance, the advantage such as construction and installation and maintenance are more convenient;
2) insulator chain is installed near pillar side, at mixing traction section, is difficult for being polluted by sootiness, has improved the electric insulating intensity of contact suspension assembly, has effectively guaranteed to transport and has protected carrying out smoothly of product work;
3) bracket and lacing wire and contact suspension, in same equipotential, are very easy to carrying out of hotline maintenance operation, thereby have reduced widely the number of times of interruption maintenance, and overhaul of the equipments has obtained initiative, meet the development tendency of contact net equipment.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment application state structural representation.
In figure: 1-insulator chain 2-bracket 3-lacing wire 4-pillar 5-handle pipe 6-contact suspension assembly
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
See Fig. 1, it is a kind of direct current contact system of the utility model straight bracket embodiment application state structural representation that insulate, comprise bracket 2, lacing wire 3, handle pipe 5, insulator chain 1 and contact suspension assembly 6, by insulator chain 1 is arranged by pillar 4 sides, be separately positioned between lacing wire 3 and pillar 4, between bracket 2 and pillar 4, make bracket 2, lacing wire 3 and contact suspension assembly 6 are in same equipotential, be very easy to carrying out of hotline maintenance operation, such as: adjust bracket deviant, adjust or change the handle pipe of bracket below, and the zigzag value of adjustment bracket below circuit, the upkeeps operation such as stagger, can directly carry out equipotential live line work, need not as in the past, apply for again interruption maintenance.
In order to improve the structural strength of bracket 2, bracket 2 is cut into by round steel pipe, and it is lightly simple that round steel pipe has structure, technological performance, construction and installation and the maintenance advantage such as more convenient.
Claims (3)
1. a direct current contact system straight bracket that insulate, comprise bracket, lacing wire, handle pipe, insulator chain and contact suspension assembly, it is characterized in that, described insulator chain arranges by pillar side, be separately positioned between lacing wire and pillar, between bracket and pillar, bracket, lacing wire and contact suspension assembly are in same equipotential.
2. a kind of direct current contact system according to claim 1 straight bracket that insulate, is characterized in that, described bracket is cut into by round steel pipe.
