[0001] The invention relates to the field of high-voltage insulation, and in particular to a detachable high-voltage busbar corner insulation sleeve. Background Art

[0002] At present, high-voltage busbars play a vital role in power transmission. However, during the installation and use of high-voltage busbars, the insulation treatment at the corners has always been a difficult problem. The traditional high-voltage busbar corner insulation method has many shortcomings.

[0003] Existing corner insulation structures are usually complex and difficult to install and disassemble. In actual applications, when the high-voltage bus needs to be repaired or some parts need to be replaced, the complex structure may result in long operation time and high cost, and may even cause damage to the bus. In addition, traditional corner insulation sleeves often lack flexibility and are difficult to adapt to the requirements of corners at different angles. In actual applications, due to the diversity of installation environments, the high-voltage bus needs to be bent at different angles, and existing insulation sleeves are difficult to meet this requirement.

[0004] Therefore, we make improvements on this and propose a detachable high-voltage busbar corner insulation sleeve. Summary of the invention

[0005] The purpose of the present invention is to address the problems raised by the current background technology.

[0016] In the scheme of this application:

[0017] 1. In order to solve the problem that the corner insulating sleeve in the prior art often lacks flexibility and is difficult to adapt to the corner requirements of different angles, the present application cooperates with the insulating sphere, the sliding ring and the positioning ring to enable the busbar to rotate freely in multiple directions, realize multi-angle bending, and meet the requirements of different installation environments and electrical layouts.

[0031] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0032] As described in the background art, the corner insulation sleeve often lacks flexibility and is difficult to adapt to the corner requirements of different angles.

[0033] In order to solve this technical problem, the present invention provides a detachable high-voltage busbar corner insulating sleeve, which is applied to flexible corners.

[0034] Specifically, please refer to Figure 1-Figure 8 A detachable high-voltage busbar corner insulating sleeve comprises a bracket 1 and a line body 2 mounted on the bracket 1, an insulating assembly 3 is arranged on the line body 2, the insulating assembly 3 comprises a corner mechanism 30 and a positioning mechanism 31, the corner mechanism 30 comprises an insulating sphere 301, a sliding ring 302 and a positioning ring 303, the insulating sphere 301 and the sliding ring 302 are both sleeved on the line body 2, and the positioning ring 303 is mounted on the sliding ring 302 and slides with the insulating sphere 301;

[0035] The wire body 2 is installed on the bracket 1, and the bracket 1 provides support for the wire body 2. When the turning angle of the wire body 2 needs to be adjusted, the insulating sphere 301 can be flexibly rotated on the wire body 2 to drive the wire body 2 to change its angle to adapt to different installation requirements. The sliding ring 302 can slide smoothly relative to the wire body 2, and the sliding friction coefficient between it and the wire body 2 is low, ensuring the convenience of operation. The positioning ring 303 is installed on the sliding ring 302 and slides tightly with the insulating sphere 301. After the wire body 2 after the corner is turned is installed again with the bracket 1 at the installation location where the corner needs to be turned, the rotation angle range of the insulating sphere 301 is limited. The positioning mechanism 31 is fixed at a specific position on the wire body 2 to ensure the stability of the wire body 2 during use, ensure the safe operation of the electrical system, and avoid the hidden danger of electrical failure due to displacement or shaking of the wire body 2.

[0036] The present invention provides a detachable high-voltage busbar corner insulating sleeve, which cooperates with the set insulating sphere 301, the sliding ring 302 and the positioning ring 303, so that the busbar can rotate freely in multiple directions and achieve multi-angle bending to meet different installation environments and electrical layout requirements. The cooperation between the sliding ring 302 and the positioning ring 303 can adapt to adjust and control the angle range, thereby improving the reliability and protection effect of the corner of the line body 2.

[0037] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0038] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0040] Please refer to Figure 4-Figure 6 , a detachable high-voltage busbar corner insulating sleeve, a sliding ring 302 of which is threadedly connected with an insulating bolt 304, and an arc-shaped insulating top block 305 is installed on the insulating bolt 304, and the insulating top block 305 is located at the corner to be turned of the line body 2 through the sliding ring 302 and the insulating bolt 304; when the corner of the high-voltage busbar needs to be adjusted, first, the insulating sphere 301 can be rotated on the line body 2 to drive the line body 2 to change its angle, and the sliding ring 302 can slide relatively on the line body 2 so that the line body 2, the positioning ring 303 is installed on the sliding ring 302, and slides with the insulating sphere 301, so that the line body 2 can adjust different corner angles and directions according to the installation environment. At the same time, when the sliding ring 302 rotates to the required corner position, the insulating bolt 304 can be rotated to push the arc-shaped insulating top block 305 close to the line body 2, thereby increasing the stability of the corner bend of the line body 2, and playing a certain supporting and fixing role on the line body 2.

[0041] By setting the mutual cooperation of the sliding ring 302, the insulating bolt 304 and the insulating top block 305, the setting of the insulating top block 305 can provide additional support and fixation for the wire body 2 during the angle adjustment process. After the insulating top block 305 contacts the wire body 2, the stability of the wire body 2 at the corner can be increased to prevent the wire body 2 from moving unnecessary due to external force or vibration during use, so as to avoid movement during installation.

[0042] Please refer to Figure 4-Figure 6 A detachable high-voltage busbar corner insulating sleeve, wherein the line body 2 is located in an insulating sphere 301 and a sliding ring 302, and the insulating sphere 301 cooperates with the sliding ring 302 to achieve angle assistance for the line body 2 through a positioning mechanism 31; the line body 2 is placed in the insulating sphere 301 and the sliding ring 302, and when the need to adjust the high-voltage busbar angle arises, the insulating sphere 301 can drive the line body 2 to rotate to drive the line body 2 to change its angle, and the sliding ring 302 can slide on the line body 2 and cooperate with the insulating sphere 301, and the positioning mechanism 31 assists the line body 2 to achieve angle change by fixing or adjusting the positions of the insulating sphere 301 and the sliding ring 302.

[0043] By cooperating with each other through the insulating sphere 301 and the sliding ring 302, the sliding ring 302 is supported and fixed in combination with the positioning mechanism 31, thereby improving the stability of the wire body 2 at the corner, realizing the regulation of the wire body 2 at the corner, and meeting the requirements of different installation environments.

[0044] A detachable high-voltage busbar corner insulation sleeve is further optimized, specifically, as Figure 5-Figure 8 As shown, the positioning mechanism 31 includes a frame 311, a soft silicone rubber sleeve 313 and a corrugated insulating sleeve 314. The frame 311 is arranged on both sides of the insulating sphere 301, and the soft silicone rubber sleeve 313 is installed on the frame 311. An insulating spiral ring 312 spirally installed with the insulating sphere 301 is installed on the soft silicone rubber sleeve 313, and a corrugated insulating sleeve 314 is installed on the soft silicone rubber sleeve 313; when the high-voltage bus needs to be positioned at an angle, the positioning mechanism 31 begins to play a role. The frame 311 is arranged on both sides of the insulating sphere 301, and the soft silicone rubber sleeve 313 is installed on the frame 311. On the one hand, it plays an insulating role, and on the other hand, it can be adjusted according to the turning angle of the line body 2 to reduce the situation of cracking and damage caused by long-term use when turning. The insulating spiral ring 312 is connected to the soft silicone rubber sleeve 313 and spirally installed with the insulating sphere 301, so that it can be disassembled according to the use needs. The corrugated insulating sleeve 314 is installed on the soft silicone rubber sleeve 313 to further enhance the insulation performance and also protect the line body 2.

[0045] By using the soft silicone rubber sleeve 313 and the corrugated insulating sleeve 314, the insulation performance of the entire device is greatly improved, and the leakage and short circuit of the wire body 2 are effectively prevented. The spiral installation method of the insulating spiral ring 312 and the insulating sphere 301 can achieve the effect of being disassembled from the wire body 2. The soft silicone rubber sleeve 313 has good flexibility and elasticity, and can adapt to insulating spheres 301 and wire bodies 2 of different sizes and shapes, thereby improving the versatility and adaptability of the device.

[0046] Further, such as Figure 7-Figure 8 It is shown that a plurality of mounting blocks 315 are installed on the corrugated insulating sleeve 314, the mounting blocks 315 are arranged in groups of two and are installed between them by insulating screws, and a plurality of insulating pressure strips 316 are connected to the mounting blocks 315; when the line body 2 needs to be positioned and insulated, the corrugated insulating sleeve 314 is wrapped on the line body 2, and a plurality of mounting blocks 315 are distributed on the corrugated insulating sleeve 314, and the mounting blocks 315 in groups of two are connected and fixed by insulating screws. After the mounting blocks 315 are fixed, the insulating pressure strips 316 connected thereto exert pressure on the corrugated insulating sleeve 314 and the line body 2 inside, so that the corrugated insulating sleeve 314 adapts to the deformation and fits tightly on the line body 2, thereby playing a better insulating and fixing role.

[0047] By cooperating with each other through the corrugated insulating tube 314, the mounting block 315 and the insulating strip 316, the fixing of the mounting block 315 and the insulating screws, and the pressing of the insulating strip 316, the corrugated insulating sleeve 314 is firmly wrapped on the line body 2, thereby improving the stability of the high-voltage busbar during use, and better controlling according to the diameter of different line bodies 2, achieving the effect of convenient disassembly and improved applicability.

[0048] A detachable high-voltage busbar corner insulation sleeve is further optimized, specifically, as Figure 5 As shown, the sliding ring 302 is located between the two insulating spheres 301, and the insulating spheres 301 are connected through the sliding ring 302, and the insulating spheres 301 and the sliding ring 302 form a hemispherical shape; because the insulating spheres 301 and the sliding ring 302 form a hemispherical shape, the hemispherical shape enables more flexibility in adapting to changes in different angles during the angle adjustment process, and also better fits with the wire body 2, ensuring that the insulation effect and the angle adjustment effect are improved.

[0049] The two insulating spheres 301 are connected by a sliding ring 302 to form a hemispherical structure, so that the angle adjustment of the line body 2 is more flexible and the angle can be adjusted in multiple directions according to actual needs.

[0050] Further, such as Figure 7-Figure 8 As shown, the insulating pressure strips 316 are grouped into three, and the insulating pressure strips 316 and the line body 2 are in a close contact and force-applying state; when fixed by the mounting block 315 and the insulating screws, the insulating pressure strips 316 apply pressure to the line body 2. Since the insulating pressure strips 316 and the line body 2 are in a close contact and force-applying state, this force-applying method enables the insulating pressure strips 316 to fit tightly to the surface of the line body 2, thereby ensuring that the corrugated insulating sleeve 314 is firmly wrapped around the line body 2, thereby achieving insulation and fixation of the high-voltage busbar.

[0051] By providing a group of three insulating pressure strips 316 to apply force closely to the wire body 2, the contact tightness between the corrugated insulating sleeve 314 and the wire body 2 can be effectively increased, the insulation effect can be further improved, and the risk of leakage and short circuit can be reduced.
