Description

Technical Field

[0001] The invention relates to the technical field of power transmission equipment, and in particular to a device for preventing insulator string whipping of an ultra-high voltage transmission line. Background Art

[0002] As an important part of modern power transmission, UHV transmission technology plays a key role in improving transmission efficiency and reducing energy consumption. Especially in areas with frequent strong winds, the design and maintenance of UHV lines face unique challenges. The tension insulator strings used in these lines are usually designed as a six-unit structure to meet the needs of high voltage levels. However, when encountering strong winds, long strings of insulators will experience complex dynamic effects, causing line dancing.

[0003] Line galloping is a nonlinear vibration caused by wind, especially in high wind sections, this vibration is aggravated, resulting in whipping effect between adjacent insulator strings. This physical impact poses a serious threat to insulators, especially for insulators made of porcelain or glass materials, which are relatively fragile and easily damaged or even exploded under the action of whipping. Damage to insulators not only affects the normal operation of the line, but the insufficient insulation distance after damage may also cause electrical faults such as short circuits, posing a direct threat to the safety of the power grid.

[0004] At present, despite significant progress in the field of UHV transmission technology, there is still a lack of efficient and reliable solutions to prevent whiplash damage to insulator strings. Existing technical measures may not be sufficient to effectively prevent insulator breakage caused by strong winds, especially under extreme climatic conditions. Therefore, developing a new technology that can effectively suppress insulator whiplash damage while ensuring stable operation of UHV transmission lines has become a key issue that the industry needs to solve urgently. Summary of the invention

Since the first positioning frame and the second positioning frame are connected by the first buffer connection assembly, sufficient gaps can be ensured between adjacent insulator strings, thereby ensuring that the insulator strings are not prone to whiplash even if they are moved towards each other when affected by external forces such as wind. In addition, due to the buffering of the first buffer connection assembly, a part of the impact force can be offset, thereby making the insulator strings less likely to collide and less likely to suffer whiplash damage.

[0031] In some embodiments of the present invention, reference Figures 1 to 3 There are two first positioning frames 3, which are symmetrically arranged. The two adjacent first positioning frames 3 are connected by a first buffer connection component 5. Specifically, the first buffer connection component 5 is connected to one end of the first positioning frame 3 away from the first clamping component 1, so that the upper and lower layers of the insulator strings can be separated.

Preferably, the number of the second positioning frames 4 can be 2, 4 or 6.

In strong winds or other extreme weather, the insulator strings will be blown to collide and whip each other. The adjacent first clamping components 1 and the second clamping components 2 are connected by the second buffer connection component 6. When the insulator string on one side approaches the other side, the force of this insulator string can be used to push the insulator string on the other side away from this insulator string, thereby avoiding the two from colliding and whipping each other.

[0036] In some embodiments of the present invention, reference Figure 2The second buffer connection assembly 6 includes a third connection member 61 , a fourth connection member 62 , a fifth connection member 63 , a sixth connection member 64 and a seventh connection member 65 .

[0037] In the above embodiment, if the insulator string installed on the second clamping assembly 2 is pushed outward relative to the insulator string on the first clamping assembly 1, since both ends of the insulator string are fixed, its movement trajectory will be in an arc shape, and the second clamping assembly 2 will be driven to rotate obliquely upward, thereby driving the arc segment of the third connecting member 61 to rotate downward, and the sixth connecting member 64 is pulled downward by the fifth connecting member 63, so that the long side of the seventh connecting member 65 rotates upward, pushing the first clamping assembly 1 to show a trend of moving away from the second clamping assembly 2, thereby preventing the two insulator strings from colliding.

[0038] In some embodiments, reference Figure 2 The second buffer connection assembly 6 also includes a limit baffle 66, which is fixed on the first positioning frame 3 and is located on the side of the seventh connecting member 65 near the short side, for limiting the rotation angle of the seventh connecting member 65.

[0039] In the above embodiment, if the insulator string installed on the second clamping assembly 2 is pushed inward relative to the insulator string on the first clamping assembly 1, since both ends of the insulator string are fixed, its movement trajectory will be in an arc shape, and the second clamping assembly 2 will be driven to rotate obliquely downward, thereby driving the arc segment of the third connecting member 61 to rotate upward, and the sixth connecting member 64 is pulled upward by the fifth connecting member 63, so that the long side of the seventh connecting member 65 rotates downward and the short side rotates upward. At this time, when it rotates to a certain angle, such as 0 to 30°, the short side of the seventh connecting member 65 will abut against the limit baffle 66, thereby limiting the second clamping assembly 2 from approaching the first clamping assembly 1, thereby achieving the purpose of separating the two strings of insulators.

[0040] When there are two groups of second clamping components 2, assuming that the second clamping component 2 on the left rotates to the left, pushing the first clamping component 1 to rotate to the right, and the two strings of insulators are separated, the short side of the seventh connecting member 65 on the right will be driven to rotate upward. At this time, the short side of the seventh connecting member 65 on the right will rotate to a certain angle, such as 0 to 30°, and the short side of the seventh connecting member 65 will abut against the limit baffle 66, thereby limiting the second clamping component 2 on the right from approaching the first clamping component 1, thereby achieving the purpose of separating the two strings of insulators.
