Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electric power equipment, and in particular relates to a novel grounding hanging ring. Background Art
[0002] The grounding ring is a device designed for grounding connection in electrical equipment and systems, usually installed on two towers at both ends of the transmission line. Its main function is to connect the grounding wire and guide the current underground, so that the transmission line between the two towers is not energized to ensure the safety of maintenance personnel. Since the transmission line generally adopts the ABC three-phase power system, the grounding ring is usually designed to be three side by side with a certain distance in the middle, and the conductive part is usually exposed.
[0003] In outdoor environments, such as on power lines, there are cases where animals such as squirrels crawl along the poles. Considering this, especially since the squirrel's tail may cross over the exposed conductive part of two grounding rings, it may cause a short circuit in the line, which not only endangers the electrical equipment, but also may harm the life of the small animal.
[0004] At the same time, since the conductive part of the grounding ring is exposed to the outdoor environment for a long time, it is subjected to wind, sun, and especially the influence of sea breeze and typhoon in coastal areas, which may cause corrosion of the conductor part and seriously affect its conductive performance. This will affect the effective grounding of the equipment and may endanger the life safety of maintenance personnel. Utility Model Content
[0005] The utility model aims to overcome the shortcomings of the prior art and provide a novel grounding hanging ring which can effectively prevent short circuit caused by foreign body interference.
[0006] The utility model adopts the following technical solutions:
[0007] A new type of grounding hanging ring is installed on a transmission line, comprising a hanging ring body, an insulating cover and a connecting assembly. The insulating cover is rotatably arranged on the hanging ring body; the connecting assembly is arranged between the insulating cover and the hanging ring body, and comprises an elastic clamp detachably arranged on the hanging ring body and a rotating part arranged on the elastic clamp and rotatably connected to the insulating cover.
[0008] Furthermore, the rotating member includes a rotating shaft arranged on the insulating cover and a rotating sleeve extending outward from an elastic clamp close to the insulating cover and sleeved on the outer periphery of the rotating shaft and rotatably connected to the rotating shaft.
[0009] Furthermore, the connection assembly also includes a locking piece arranged between the elastic clamp and the hanging ring body.
[0010] Furthermore, the locking member includes two locking parts arranged on one side of the elastic clamp relatively to each other and a locking bolt arranged between the two locking parts.
[0011] Furthermore, the locking portion is formed by extending outward from a side of the elastic clamp close to the hanging ring body.
[0012] Furthermore, the insulating cover includes an arc-shaped cover body and two yielding portions which are arranged relatively at the upper and lower ends of the arc-shaped cover body, and the yielding portions are opposite to the hanging ring body.
[0013] Furthermore, the hanging ring body includes a connection block connected to the transmission line and a hanging ring frame arranged on one side of the connection block for hanging a grounding rod, the hanging ring frame is provided with a conductive part connected to the grounding rod, and the insulating cover is arranged on the same side as the conductive part.
[0014] It can be seen from the above description of the utility model that compared with the prior art, the beneficial effects of the utility model are as follows: the application cooperates the hanging ring body, the insulating cover rotatably arranged on the hanging ring body, and the connecting assembly arranged between the insulating cover and the hanging ring body, and defines the specific structure of the connecting assembly, so that the insulating cover can rotate back and forth relative to the hanging ring body. When the operator needs to hang the grounding hanging ring, the grounding rod pushes the insulating cover open, so that the insulating cover rotates in the direction away from the hanging ring body to expose the hanging ring body; when the operator removes the grounding rod, the insulating cover rotates in the direction close to the hanging ring body under the action of gravity, and covers the hanging ring body, effectively preventing the short circuit between two adjacent grounding hanging rings caused by foreign body interference, and improving the safety and stability between the two adjacent grounding hanging rings;
[0015] The arc-shaped cover body can maximize the coverage of the conductive part of the hanging ring body, effectively preventing the interference of the external environment on the conductive part; through the two yielding parts arranged at the upper and lower ends of the arc-shaped cover body, the insulating cover can fit the hanging ring body more closely, providing more comprehensive protection for the hanging ring body.

[0027] To sum up, with the help of the above-mentioned technical scheme of the utility model, through the cooperation between the hanging ring body 1, the insulating cover 2 rotatably arranged on the hanging ring body 1 and the connecting component 3 arranged between the insulating cover 1 and the hanging ring body 2, the insulating cover 2 can be rotated back and forth relative to the hanging ring body 1, effectively preventing the short circuit between the two adjacent grounding hanging rings caused by foreign interference, and improving the safety and stability between the two adjacent grounding hanging rings; in addition, the arc-shaped cover body 21 can maximize the coverage of the conductive part 13 of the hanging ring body 1, effectively preventing the external environment from interfering with the conductive part 13; in addition, through the two yielding parts 22 arranged at the upper and lower ends of the arc-shaped cover body 21, the insulating cover can fit the hanging ring body more closely, providing more comprehensive protection for the hanging ring body.
