Description

Technical Field

[0001] The invention relates to the technical field of tube busbar overlap, and in particular to a connection device and an operation method suitable for tube busbar overlap. Background Art

[0002] The tubular busbar, also known as the "tubular busbar", is made of copper and aluminum materials with high conductivity. It plays the role of transmitting current and has the ability to collect and distribute electricity. It is a commonly used electrical accessory in high and low voltage complete switchgear. For the overlapping of tubular busbars, specific connection devices are required to ensure the reliability, safety and efficiency of the connection.

[0003] For example, the patent publication number is "CN111786190A", and the name is "A overlapping structure and overlapping method of a tubular busbar". The above-mentioned device first embeds two inner steel sleeves at the two ends of the two tubular busbars respectively, aligns the hole positions, and then respectively sleeves four conductive rings on the two ends of the two tubular busbars in pairs, and the grooves of the three clamping plates respectively accommodate the four conductive rings. Finally, the holes of the clamping plates are aligned with the holes of the tubular busbars, and the bolts are penetrated and tightened in turn. After the two tubular busbars are overlapped and energized, the current is conducted through the contact points between the two tubular busbars and the clamping plates and the elastic contacts on the conductive rings.

[0004] When the above device is used to overlap the tubular busbars, the distance between the two tubular busbars cannot be controlled, and the above overlapping structure cannot be flexibly adjusted, which may lead to loose connection, thereby affecting the stability and safety of power transmission. In actual use, it is not just the position of one tubular busbar that is overlapped, and multiple tubular busbars may be overlapped at the same time, and the above device can only achieve the connection between two busbars.

[0062] An operation method suitable for overlapping a tube busbar adopts the above-mentioned connection device suitable for overlapping a tube busbar, and the operation method comprises:

[0063] Removing the insulation layer: removing the insulation layer at the overlapping position on the tube busbar 1;

[0064] Preliminary installation: one end of the tube busbar 1 and the contact assembly 2 are installed with each other;

[0065] Installation of connection assembly 3: Install the tube busbar 1 and connection assembly 3;

[0066] Installation of the protection component 4: Install the protection component 4 on the outer wall of the connection component 3;

[0067] Filling the insulation layer: A new insulation layer is set between the connecting device and the existing insulation layer on the busbar 1.

[0068] The conductive parts used in the contact assembly 2 are in contact with the tubular busbar 1, thereby ensuring that the connection assembly 3 can smoothly conduct current with the conductive parts, thereby realizing the current transmission between the tubular busbars 1. Since there is an insulating layer on the tubular busbar 1, when installing the connection device, it is necessary to remove the insulating layer of the overlap area. After the connection device is installed, the insulating component is installed in the area between the connection device and the tubular busbar 1.

[0069] Embodiment 1: Install the contact assembly 2 on the tubular bus 1, and realize the electrical connection between the No. 1 conductive member 202 and the tubular bus 1, wherein the No. 1 conductive member 202 needs to ensure sufficient contact with the tubular bus 1 after installation, so as to ensure the stability of subsequent current transmission, and the use of the No. 1 conductive member 202 can facilitate the subsequent installation of the connection assembly 3.

[0070] Rotating the threaded connector 301 enables threaded connection between the threaded connector 301 and the No. 1 conductive member 202, and the distance between the threaded connector 301 and the No. 1 conductive member 202 becomes shorter, so that the No. 1 elastic conductive member 302 is squeezed between the threaded connector 301 and the No. 1 conductive member 202. This design ensures that current is transmitted between the threaded connector 301 and the No. 1 conductive member 202. At the same time, the design of the conductive slip ring 303 ensures that current is transmitted when the angle between the threaded connector 301 and the conductive slip ring 303 changes. There is a No. 1 conductive member fixedly connected between the two conductive rings. According to the above, current transmission between the two busbars 1 can be achieved.

[0071] The conductive part is protected by the protection component 4. The outer wall of the No. 1 fixing part 201 is installed with a No. 1 sleeve 401. The No. 2 sleeve 402 and the No. 1 sleeve 401 are slidably connected to adapt to the non-fixed distance between the two busbars 1. The No. 1 elastic damper 502 is fixedly connected between the two No. 1 sleeves 401. The No. 1 elastic damper 502 applies force to the No. 1 sleeve 401 so that the two No. 1 sleeves 401 tend to separate. The No. 1 threaded rod 504 rotates and moves to limit the distance between the ring 307 and the No. 3 sleeve 501, thereby controlling the distance between the two ends of the No. 1 elastic damper 502, so that the two No. 1 sleeves 401 can be controlled to be at a suitable distance.

[0072] Embodiment 2: The working principle of the No. 2 telescopic component 7 is the same as that of the No. 1 telescopic component 5. By rotating the No. 2 threaded rod 703, the No. 2 threaded rod 703 turns and moves, so as to control the distance between the No. 2 elastic damper 702, and ensure that the distance between the conductive plug 305 and the No. 2 conductive member 204 can be changed within a specified range. The connecting component 3 is installed on the outer wall of the No. 2 fixing member 203, and the two No. 4 sleeves 701 are moved to connect the conductive plug 305 and the conductive socket 308 in the No. 4 sleeve 701. At the same time, the distance between the conductive plug 305 and the conductive socket 308 becomes closer, so that the elastic conductive member is squeezed between the conductive plug 305 and the conductive socket 308, thereby ensuring the conductive stability between the conductive plug 305 and the conductive socket 308. The No. 6 conductive wire 324 has variable lengths at both ends. After the installation between the conductive plug 305 and the conductive socket 308 is achieved, the protective component 4 is installed. The protective component 4 is not specifically described in this embodiment. The protective component 4 can protect the connecting component 3.

[0073] Embodiment 3: The structure of the No. 3 telescopic assembly 6 is the same as that of the No. 2 telescopic assembly 7. The specific structure of the No. 3 telescopic assembly 6 is not described here. The fixed cylinder is moved so that the two limiting inclined blocks 313 contact each other and are squeezed, so that the limiting inclined block 313 moves, and the No. 3 spring damper 312 is compressed. After the limiting inclined blocks 313 are separated, due to the elastic force inside the No. 3 spring damper 312, the limiting inclined block 313 moves in the opposite direction, so that the limiting inclined block 313 realizes the restriction between the two No. 3 fixed cylinders 310. The No. 3 telescopic assembly 6 applies force to the moving cylinder 311. , thereby causing a force to be applied between the two moving cylinders 311, and the structural setting for the moving cylinder 311, coupled with the design of the No. 4 spring shock-absorbing damper 327, when the No. 4 spring shock-absorbing damper 327 is always in a compressed state, when the two limiting cylinders are fixed in position relative to each other by the limiting bevel 313, the No. 4 spring shock-absorbing damper 327 always applies a force to the No. 3 connecting conductive member 322, so that the two No. 3 connecting conductive members 322 on the two moving cylinders 311 come into contact with each other and exert force on each other, thereby ensuring good contact between the three connecting conductive members and ensuring the stability of the transmitted current.

[0074] The designs of the first, second and third embodiments can provide effective overlap for the distances between the end faces of different tubular busbars 1. At the same time, since the overlap may occur between multiple tubular busbars 1, the structure also provides effective assistance for the overlap between multiple tubular busbars 1 in the subsequent sixth embodiment. By adopting the design of elastic conductive parts, conductive slip rings 303 and spring dampers in the contact assembly 2 and the conductive assembly, sufficient contact between the conductive parts and stable transmission of current are ensured. Even when the external environment or the tubular busbar 1 itself causes a slight displacement, the tightness of the connection can be maintained, thereby avoiding the problem of unstable or interrupted power transmission caused by loose connection.

[0075] Embodiment 4: The No. 1 fixing ring 314 and the No. 4 conductive member 208 are fixed to each other, and at the same time, a No. 5 conductive wire 317 is fixedly connected between the two busbars 1, and a No. 4 conductive wire 315 is fixedly connected between the No. 1 fixing ring 314. The No. 1 fixing ring 314 and the No. 5 conductive wire 317 are arranged to increase the conductive area of ​​the busbar 1. This method avoids the electrical connection between the two ends of the traditional busbar 1 by increasing the conductive area, thereby ensuring that the heat generated when the current is transmitted in the overlapping area is reduced. Note that a single conductive wire in the No. 4 conductive wire 315 and the No. 5 conductive wire 317 can realize the transmission of current, wherein the protection component 4 is described according to the specific structure and size of the connection component 3. The protection component 4 of this embodiment is installed on the No. 4 fixing member 207.

[0076] Embodiment 5: In actual installation, considering the situation that overlapping will be performed at the middle position of the tubular busbar 1, this embodiment is provided. By overlapping at the middle position of the tubular busbar 1, the current carrying capacity can be effectively expanded or increased. At the same time, the embodiment 5 can also be used with the structures in the embodiments 1, 2 and 3. The embodiments 1, 2 and 3 are only the connections at the end positions of the tubular busbar 1. By modifying the structures in the embodiments 1, 2 and 3, the overlapping between the middle position of the tubular busbar 1 and the end point of another tubular busbar 1 can be achieved. Further, the overlapping between the middle positions of two tubular busbars 1 can be achieved, wherein the No. 6 conductive member 211 and another tubular busbar 1 are connected through the connecting assembly 3. At this time, the No. 6 conductive member 211 can be regarded as the tubular busbar 1, and the connecting device in the embodiments 1, 2 and 3 can be applied to the overlapping position.

[0077] The contact assembly 2 is installed in the middle position of the tubular busbar 1, and the No. 3 threaded rod 212 is rotated. The No. 3 threaded rod 212 rotates and moves, so that the No. 5 fixing part 209 and the limiting block 210 can effectively clamp the tubular busbar 1. Then, the connecting assembly 3 is installed between the No. 6 conductive part 211 and another tubular busbar 1. After the connecting assembly 3 is installed, the protective assembly 4 is installed.

[0078] If the overlap of the middle position of the two busbars 1 is to be realized, the contact component 2 is installed in the middle position of the two busbars 1, and then the connection component 3 is installed between the two No. 6 conductive parts 211, so that the overlap of the middle position of the two busbars 1 can be realized.

[0079] Embodiment 6: A contact component 2 is installed at one end of the tubular busbar 1, and a conductive component is installed between the fifth conductive member 321 and the contact component 2, wherein a conductive member exists in the contact component 2, and the conductive component realizes the current transmission between the conductive member and the fifth conductive member 321, and the conductive component and the connecting component 3 have the same function, so the conductive component can adopt the connecting component 3 in Embodiment 1, Embodiment 2, Embodiment 3 and Embodiment 4, so as to realize the current transmission between the conductive member and the fifth conductive member 321, wherein the shape of the protection component 4 will be designed in detail according to the specific structure of the conductive component, and the difference between Embodiment 6 and Embodiment 1, Embodiment 2, Embodiment 3 and Embodiment 4 lies in the position of the main conductor 319 and the eighth conductive wire 320, and the fifth conductive member 320 is fixedly connected to the eighth conductive wire 320 1. The fifth conductive member 321 and the contact assembly 2 are electrically connected through a conductive assembly, wherein the conductive assembly can be the connection assembly 3 in Embodiment 1, Embodiment 2, Embodiment 3 and Embodiment 4. The specific structure of the conductive assembly is not described herein. This embodiment can realize the overlap between multiple tube busbars 1 on the basis of other embodiments. This embodiment can be used to expand or increase the current carrying capacity. Through the setting of the main conductor 319, the connection assembly 3 is provided with an intermediate point for power transmission. The contact assembly 2 and the connection assembly 3 on the tube busbar 1 are connected to the connection assembly 3 at the position of the main conductor 319, thereby realizing the overlap of multiple tube busbars 1. This design can effectively help the tube busbar 1 to expand or increase the current carrying capacity, and improve the scope of use of the connection device.

[0080] Through the setting of the connection component 3, telescopic components are designed, such as the No. 1 telescopic component 5, the No. 2 telescopic component 7, etc., and the distance between the two tube busbars 1 can be flexibly adjusted by rotating the threaded rod to control the distance of the elastic damper. This design enables the actual distance between the tube busbars 1 to achieve tight and stable overlap, greatly improving the flexibility and adaptability of the overlap. At the same time, the detachable connection in the connection component 3 provides effective assistance for the subsequent overlap between multiple tube busbars 1, ensuring the scope of use of the connection device.

[0081] When the tubular busbar 1 is overlapped, the insulating layer at the overlapped position is removed to ensure the installation of the connection component 3, thereby ensuring good contact between the conductive part and the tubular busbar 1 in the connection device, and avoiding the insulation layer from affecting the installation of the connection device. After the connection device is installed, a new insulation layer is installed again in the area between the connection device and the insulation layer to ensure the insulation effect of the connection device position. At the same time, the protection component 4 is made of insulating material, or an insulating coating is applied to the outer layer of the protection component 4 components to ensure insulation inside the connection device.

[0082] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the attached embodiments and their equivalents.
