Description

Technical Field

[0001] The invention relates to the field of devices or equipment for damping mechanical oscillation of a circuit, and in particular to a conductive rod vibration reduction component and a conductive rod. Background Art

[0002] Gas-insulated metal-enclosed transmission line equipment (GIL) and high-voltage busbars are both important components of the power system. For high-voltage busbar structures, the higher the voltage level, the longer the busbar, the longer the conductive rod, and the more prone to vibration; for gas-insulated metal-enclosed transmission line equipment (GIL), the conductors at all voltage levels are very long and prone to vibration. The two ends of the conductive rod are constrained by electrical connection with the supporting insulator. During the power transportation process, the conductive rod is easily affected by environmental factors and other factors, and it is also affected by electric force to produce vibration. Under the action of repeated vibration, the two ends of the conductive rod are prone to wear. The wear of the two ends of the conductive rod may form metal particles, which may increase the contact resistance and affect the current carrying capacity and insulation performance. These are not allowed to occur, but the vibration of the conductive rod is inevitable, so the conductive rod needs to be treated for vibration reduction. Summary of the invention

[0003] The object of the present invention is to provide a conductive rod vibration reduction assembly to solve the problem that the conductive rod vibrates under the action of external force, causing wear at both ends of the conductive rod and affecting its current carrying capacity and insulation performance.

[0004] The present invention also aims to provide a conductive rod to solve the problem that the conductive rod vibrates under the action of external force, causing wear at both ends of the conductive rod and affecting its current carrying capacity and insulation performance.

[0008] Furthermore, there are two damping springs which are symmetrically installed on both sides of the counterweight.

[0009] Furthermore, the conductive rod vibration reduction assembly also includes a wedge ring with a wedge-shaped cross section for wedging between the outer wall of the fixing ring and the inner wall of the conductive rod, and the fixing ring and the conductive rod can be tightly fitted through the wedge ring.

[0010] Beneficial effects: The conductive rod vibration reduction assembly of the present invention is a pioneering invention. When the conductive rod vibrates, the counterweight block connected to the damping spring inside the conductive rod is not synchronized with the vibration of the conductive rod, thereby playing a damping role to reduce the vibration amplitude of the conductive rod. The conductive rod vibration reduction assembly of the present invention can effectively reduce the vibration impact of the conductive rod without affecting the structural performance of the conductive rod, thereby improving the reliability and service life of the conductive rod.

[0019] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0020] Aiming at the problem that the conductive rod is prone to vibration under the action of external force, which causes wear at both ends of the conductive rod and thus affects the current carrying capacity and insulation performance of the conductive rod, the present invention proposes a conductive rod vibration reduction assembly. The conductive rod vibration reduction assembly weakens or offsets the vibration of the conductive rod in an energy-absorbing manner, thereby protecting the conductive rod.

[0021] In a basic embodiment, the conductive rod vibration reduction assembly is installed inside the conductive rod 4, the fixing ring 1 of the conductive rod vibration reduction assembly is fixedly connected to the inner wall of the conductive rod 4, a damping spring is fixedly connected to the inner wall of the fixing ring 1, and a counterweight 5 is fixedly connected to the damping spring. When the conductive rod 4 vibrates, the counterweight 5 connected to the first damping spring 3 inside the conductive rod 4 will also vibrate, but since the vibration of the counterweight 5 is not synchronized with the vibration of the conductive rod 4, a damping effect is played, and the first damping spring 3 and the counterweight 5 absorb the vibration energy to reduce the vibration amplitude of the conductive rod 4.

[0022] In a preferred embodiment, the damping spring extends along the radial direction of the fixing ring 1 .

[0023] In other embodiments, the damping spring may extend along other directions of the fixing ring 1 .

[0024] In a preferred embodiment, there are at least two damping springs, which can further reduce the vibration amplitude of the conductive rod 4 .

[0025] In a preferred embodiment, Figure 1 As shown, there are two damping springs, the first damping spring 3 and the second damping spring 6 are symmetrically installed on both sides of the counterweight 5. When the conductive rod 4 vibrates, the counterweight 5 and the damping spring will also vibrate. The vibration of the counterweight 5 and the damping spring is not synchronized with the conductive rod 4, thereby playing a damping role and reducing the amplitude of the vibration of the conductive rod 4.

[0026] In other embodiments, there may be multiple damping springs which can also play the role of reducing the vibration amplitude of the conductive rod 4 .

[0027] In a preferred embodiment, Figure 2As shown, a first wedge-shaped ring piece 2 and a second wedge-shaped ring piece 7 are arranged between the fixing ring 1 and the inner wall of the conductive rod 4. The first wedge-shaped ring piece 2 and the second wedge-shaped ring piece 7 form a wedge-shaped ring for fastening the fixing ring 1 and the conductive rod 4. When the vibration reduction assembly is installed in the conductive rod 4, the vibration reduction assembly is first placed in the conductive rod 4, and then the first wedge-shaped ring piece 2 and the second wedge-shaped ring piece 7 are pushed into the gap between the fixing ring 1 and the conductive rod 4 by a tool to realize the fastening fit between the vibration reduction structure and the conductive rod 4. When the conductive rod 4 vibrates, the counterweight block 5 connected to the first damping spring 3 and the second damping spring 6 inside the conductive rod 4 will also vibrate. The vibration of the counterweight block 5 is not synchronized with the vibration of the conductive rod 4, thereby playing a damping role; when the conductive rod 4 vibrates, the vibration reduction structure can absorb the vibration energy to reduce the vibration amplitude of the conductive rod 4. At the same time, the vibration amplitude of the conductive rod 4 can be further reduced by adjusting the stiffness of the first damping spring 3 and the second damping spring 6 and the mass of the counterweight block 5.

[0028] In other embodiments, the fixing ring 1 and the conductive rod 4 may be in direct contact and fastened fit.

[0029] In a preferred embodiment, Figure 3 As shown, a plurality of vibration reduction components are arranged inside the conductive rod 4, which can further reduce the vibration of the conductive rod 4. Both ends of the conductive rod 4 are fixedly connected to the electrical connection 9 through the contact fingers 10, and the electrical connection 9 is fixedly connected to the support insulator 8. When the conductive rod 4 vibrates, the counterweight blocks of the plurality of vibration reduction components inside the conductive rod 4 will also move. The movement of the counterweight blocks is not synchronized with the conductive rod 4, thereby playing a damping role. When the conductive rod 4 vibrates, the vibration reduction components can absorb the vibration energy and reduce the vibration amplitude of the conductive rod 4.

[0030] Aiming at the problem that a conductive rod is prone to vibration under the action of external force, which causes wear at both ends of the conductive rod and thus affects the current carrying capacity and insulation performance of the conductive rod, the present invention proposes a conductive rod in a targeted manner.

The specific implementation of the vibration reduction assembly is as described above and will not be repeated here.
