Technical Field

[0002] Composite insulators are a common insulating element in power systems. They play an important role in overhead transmission lines. Composite insulators are a special type of insulating control used to support transmission and distribution lines and transmit electricity to user terminals. Composite insulators consist of three parts: a rod, a core rod, and a sleeve. The inner core frame is usually made of composite materials or metals and is connected to the conductor through different forms of joint designs.

[0003] The installation of composite insulators is generally done by connecting one end to the outside of the high-voltage line and the other end to a supporting tower to prevent the current of the high-voltage line from flowing back to the ground through the supporting tower. The wind flow in the sky will blow the high-voltage line to shake, causing the composite insulator to shake along with the high-voltage line to reduce impact force. The prior art provides a lifting ring at one end of the composite insulator and sleeves it on the supporting tower so that the composite insulator can shake along with the high-voltage line to reduce impact force. However, the lifting ring sleeve installation method cannot limit the swing amplitude of the composite insulator, which limits its stability and may cause the composite insulator to swing too much, causing wear and damage. There is a need for a composite insulator for communications that can limit the swing amplitude of the composite insulator and improve stability.

[0004] In view of this, the utility model provides a high-stability composite insulator for communication. Utility Model Content

[0023] The prior art provides a lifting ring at one end of the composite insulator and sleeves it onto a supporting tower so that the composite insulator can swing along with the high-voltage line to reduce impact force. However, the sleeve installation method of the lifting ring cannot limit the swing amplitude of the composite insulator, thereby limiting its stability, which may cause the composite insulator to swing too much and cause wear and damage. Therefore, a composite insulator for communications is needed that can limit the swing amplitude of the composite insulator and improve stability.

[0024] like Figure 1-3 As shown, the device includes a composite insulator body 1, one end of the composite insulator body 1 is provided with an installation set 2 for installing and connecting the composite insulator body 1, the other end of the installation set 2 is installed with a connecting sleeve 301, one side of the connecting sleeve 301 is provided with a placement groove 302, the top of the connecting sleeve 301 is provided with a placement opening 303 that penetrates into the placement groove 302, a limiting component 3 for limiting the shaking of the composite insulator body 1 is clamped in the placement groove 302 inside the connecting sleeve 301, and the inside of the connecting sleeve 301 is clamped with the limiting component 3 for limiting the shaking of the composite insulator body 1, thereby limiting the shaking of the composite insulator body 1 and increasing stability.

[0025] The composite insulator body 1 and the limiting assembly 3 are connected by installing the sleeve 2, and the limiting assembly 3 is sleeved on the outer surface of the clamping ring 307 to limit the swing amplitude of the composite insulator body 1, thereby improving the stability of the installation connection of the composite insulator body 1.

[0026] First, the specific structure of the limiting component 3 is disclosed. The limiting component 3 includes three studs 304 threadedly connected to the connecting sleeve 301. One end of the three studs 304 passes through the connecting sleeve 301 and is threadedly connected to a nut 305. The other end of the three studs 304 is arranged in the placement groove 302 and fixedly installed with three limiting rings 306. The inside of the three limiting rings 306 is clamped with a snap ring 307.

[0027] A connecting column 4 is fixedly mounted on one end of the snap ring 307 , and a mounting seat 5 for fixing the snap ring 307 is fixedly mounted on one end of the connecting column 4 .

[0028] When installing the limit assembly 3, first screw two studs 304 inside the connecting sleeve 301, one end of the stud 304 passes through the outside of the connecting sleeve 301, and is threadedly connected through the nut 305. The two studs 304 are installed inside the connecting sleeve 301, and then the clamping ring 307 is placed in the placement opening 303 at the top of the connecting sleeve 301, so that the clamping ring 307 is placed inside the placement groove 302, and the last stud 304 is installed inside the connecting sleeve 301 on the top of the clamping ring 307. The three studs 304 are distributed in a circular array. The limiting ring 306 at one end of the column 304 limits the clamping ring 307 in the middle of the three studs 304, limits the top of the clamping ring 307, and then the mounting seat 5 is fixedly installed on the supporting power tower, and the clamping ring 307 at one end of the connecting column 4 is fixedly installed, so that the connecting sleeve 301 can only swing around the clamping ring 307 in the space formed by the three studs 304 and the limiting ring 306, avoiding the composite insulator body 1 connected to one side of the connecting sleeve 301 from being damaged by a large swing, achieving the effect of limiting the swing amplitude of the composite insulator body 1. Make the composite insulator body 1 more stably connected.

[0029] The improvement of this embodiment is that: through the structure of the connecting sleeve 301 and the clamping ring 307, the effect of limiting the swing amplitude of the composite insulator body 1 is achieved, and the problem of large swing amplitude and low stability of the composite insulator body 1 existing in the prior art is solved.

[0030] Due to the prior art of how to connect the composite insulator body 1 and the limit assembly 3, Figure 1 A second embodiment of the present utility model is shown.

[0031] The specific structure of the installation kit 2 is disclosed again. The installation kit 2 includes a connecting rod 201 for connecting and fixing the connecting sleeve 301. A ring 202 for connecting and fixing the rod body 101 is fixedly installed at one end of the connecting rod 201. The outer surface of the ring 202 is provided with an insertion port 203.

[0032] The rod body 101 of the composite insulator body 1 can be connected and fixed through the plug interface 203 opened by the ring 202, and then the connecting sleeve 301 of the limiting component 3 can be fixedly connected through the connecting rod 201 on the other side of the ring 202, so as to achieve the effect of connecting and installing the composite insulator body 1 and the limiting component 3.

[0033] The improvement of this embodiment is that the composite insulator body 1 and the connecting sleeve 301 are fixedly connected by the structure of the ring 202 and the connecting rod 201, thereby solving the problem of inconvenient connection between the limit assembly 3 and the composite insulator body 1 in the prior art.

[0034] Considering the problem of how to install the composite insulator body 1 into the installation set 2 in the second embodiment, combined with Figure 1 and Figure 4 Specifically, the composite insulator body 1 comprises a rod body 101 , an umbrella cover 102 is fixedly mounted on the outer surface of the rod body 101 , and a fixing ring 103 for fixing and limiting is mounted on the bottom of the umbrella cover 102 .

[0035] By installing multiple umbrella sleeves 102 on the outer surface of the rod body 101, the creepage distance of the current is increased. A fixing ring 103 is installed at the bottom of each umbrella sleeve 102 on the outer surface of the rod body 101, so that the umbrella sleeve 102 can be installed more firmly. The ring 202 is plugged and fixedly connected to one end of the rod body 101 to achieve the connection with the composite insulator body 1, and the other part of the rod body 101 is also set to a clamping ring 307, which is also installed by clamping to limit its shaking amplitude and increase stability.

[0036] In summary, the working principle of this solution is as follows:

[0037] When installing the limit assembly 3, first screw two studs 304 inside the connecting sleeve 301, one end of the stud 304 passes through the outside of the connecting sleeve 301, and is threadedly connected through the nut 305. The two studs 304 are installed inside the connecting sleeve 301, and then the clamping ring 307 is placed in the placement opening 303 at the top of the connecting sleeve 301, so that the clamping ring 307 is placed inside the placement groove 302, and the last stud 304 is installed inside the connecting sleeve 301 on the top of the clamping ring 307. The three studs 304 are distributed in a circular array. The limiting ring 306 at one end of the column 304 limits the clamping ring 307 in the middle of the three studs 304, limits the top of the clamping ring 307, and then fixes the mounting seat 5 on the supporting power tower to fix the clamping ring 307 at one end of the connecting column 4, so that the connecting sleeve 301 can only swing around the clamping ring 307 in the space formed by the three studs 304 and the limiting ring 306, avoiding the composite insulator body 1 connected to one side of the connecting sleeve 301 from being damaged by a large swing, achieving the effect of limiting the swing amplitude of the composite insulator body 1. Make the composite insulator body 1 more stably connected;

[0038] The rod body 101 of the composite insulator body 1 can be connected and fixed through the plug interface 203 opened by the ring 202, and then the connecting sleeve 301 of the limiting component 3 can be fixedly connected through the connecting rod 201 on the other side of the ring 202, so as to achieve the effect of connecting and installing the composite insulator body 1 and the limiting component 3.
