Abstract
The utility model provides a closed transmission line contact shield cover guide ring structure, is including touching seat and contact, the contact is inserted and is provided with the shield cover on the outer wall that touches seat one side, the shield cover package is touching the outer wall of seat, and the inboard that the shield cover inserted the end is fixed and is provided with the guide ring, and the shield cover is provided with the tie coat within the guide ring. The invention aims to provide a connecting contact with a guide ring structure, which improves the tightness of the joint of the contact and a contact seat through the guide ring and avoids discharge accidents.
Description
Technical Field
The invention relates to the technical field of power transmission and transformation, in particular to a guide ring structure of a contact shielding case of a closed power transmission line.
Background
At present, high-voltage switches and pipeline transmission lines are successfully applied to the field of power transmission and transformation, and mainly comprise parts such as a shell, a conductor, an insulating part and the like. When the line is long, the connection needs to be carried out through the bus unit, and the connection part mostly adopts a mode that the contact is inserted into the contact seat. The contact base is internally provided with a contact finger, and the contact base are in line contact connection through the contact finger so as to conduct electricity and realize the transmission of electric energy. However, when the existing contact is connected with the contact seat, the shielding cover at the contact connecting end is easy to collide with the conductor, so that the conductor is damaged, and the contact is not tightly connected with the contact seat. When the contact is used for a long time, the connection part of the contact and the contact seat can absorb particles and dust in the environment due to the change of expansion with heat and contraction with cold, and the discharge accident is easily caused.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a connecting contact with a guide ring structure, wherein the tightness of the joint of the contact and a contact seat is improved through the guide ring, and the discharging accident is avoided.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
the utility model provides a closed transmission line contact shield cover guide ring structure, is including touching seat and contact, the contact is inserted and is provided with the shield cover on the outer wall that touches seat one side, the shield cover package is touching the outer wall of seat, and the inboard that the shield cover inserted the end is fixed and is provided with the guide ring, and the shield cover is provided with the tie coat within the guide ring.
Further, the guide ring is made of wool felt or polytetrafluoroethylene.
Furthermore, the adhesive layer is made of adhesive sticker.
Compared with the prior art, the invention has the following beneficial effects:
the guide ring arranged on the inner side of the shielding cover is made of wool felt or polytetrafluoroethylene, can be flexibly and conveniently arranged on the shielding cover, has elasticity and can play a role in supporting the shielding cover, and meanwhile, the shielding cover is prevented from colliding with a conductor to cause damage. The guide ring can improve the tightness of the joint of the contact and the contact seat, and metal particles generated in the movement process of the contact and the contact seat are adhered by the non-setting adhesive on the inner wall of the shielding cover, so that particles caused by thermal expansion, cold contraction and the like in the installation process and the operation process can be absorbed, the metal particles generated by friction are limited to jump out, the particles are limited in the shielding cover, and the generation of discharge accidents is reduced.

1-contact seat, 2-guide ring, 3-shielding case, 4-contact finger, 5-contact and 6-adhesive layer.
Detailed Description
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
As shown in fig. 1 and 2, the guide ring structure of the contact shield of the enclosed power transmission line comprises a contact base 1 and a contact 5, wherein a shield 3 is arranged on the outer wall of one side of the contact 5, which is inserted into the contact base 1, the shield 3 is wrapped on the outer wall of the contact base 1, a guide ring 2 is fixedly arranged on the inner side of the insertion end of the shield 3, and an adhesive layer 6 is arranged inside the guide ring 2 of the shield 3; the guide ring 2 is made of wool felt or polytetrafluoroethylene; the adhesive layer 6 is made of adhesive sticker.
The shielding cover 3 is arranged at the connecting part of the contact 5 and the contact seat 1, and mainly plays a role of uniform electric field, so that the surrounding electric field can be transited stably. A guide ring 2 is arranged in the shielding cover 3, and the guide ring 2 can absorb foreign matters generated when the contact 5, the contact finger 4 are inserted and the contact 5 and the contact seat 1 move relatively due to expansion with heat and contraction with cold besides the positioning and guiding functions. The guide ring 2 is composed of wool felt or polytetrafluoroethylene, the flexible guide ring 2 has certain elasticity, the effect of supporting the shielding cover 3 can be achieved, and meanwhile the shielding cover 3 is prevented from colliding with the conductor to cause damage. The guide ring 2 can improve the tightness of the joint of the contact 5 and the contact seat 1, and can adhere metal particles generated in the movement process of the contact 5 and the contact seat 1 through the non-setting adhesive on the inner wall of the shielding cover 3, so that particles caused by thermal expansion, cold contraction and the like in the installation process and the operation process can be absorbed, the metal particles generated by friction are limited to jump out, the particles are limited in the shielding cover 3, and the generation of discharge accidents is reduced.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
