Description

Technical Field

[0001] This utility model belongs to the field of high voltage switch technology, specifically, it relates to a cable terminal structure. Background Technology

[0002] Most substations nowadays have cable termination structures. Cable terminations, as the end interfaces of cable lines, connect cables to transformers, switchgear, and other equipment to enable the transmission of electrical energy or signals. In GIS (Gas Insulated Switchgear), cable terminations are also used to connect busbars to high-voltage cables, enclosed in SF6 gas to improve insulation reliability.

[0003] Existing cable termination structures, such as the quick-plug T-type cable termination disclosed in CN217063241U, only have one adapter, which limits their ability to be modified for future wiring or to add circuits. Therefore, improving the scalability of cable terminations is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0044] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0045] Figure 1 A cross-sectional view of the cable termination structure of this application is shown. Figure 2 This application is shown Figure 1 Cross-sectional view of the casing of the cable terminal structure, based on Figures 1 to 2 As shown, this application provides a cable termination structure, including a housing 100, a conductive assembly 200, an adapter 300, a first conductor 400, and a second conductor 500; the housing 100 has a cavity 110 inside, and the conductive assembly 200, the adapter 300, the first conductor 400, and the second conductor 500 are all disposed within the cavity 110 of the housing 100; the first conductor 400, the second conductor 500, and the conductive assembly 200 are respectively located on three sides of the adapter 300, and are all electrically connected to the adapter 300; wherein, the first conductor 400... 00. The second conductor 500 is detachably connected to the adapter 300; the housing 100 has a first through hole 120 opposite to the first conductor 400, and a second through hole 130 opposite to the second conductor 500; the housing 100 has a guide hole 140 for inserting a cable connector 600; the cable connector 600 is inserted into the cavity 110 of the housing 100 through the guide hole 140, and the cable connector 600 is electrically connected to the adapter 300 through the guide assembly 200.

[0046] The cable terminal structure of this application includes an adapter 300, which electrically connects conductors in different directions (i.e., the first conductor 400 and the second conductor 500). Furthermore, the cable terminal housing 100 of this application has through holes, each corresponding to a conductor in a different direction, allowing the conductors to pass through and connect to external equipment. Because the adapter 300 can detachably connect both the first conductor 400 and the second conductor 500 in different directions, the cable terminal of this application can simultaneously connect to external equipment in different locations. Furthermore, the cable terminal of this application can select any direction of conductor to connect to the GIS equipment based on its location or specific connection requirements. Specifically, it can choose to connect the first conductor 400 through the first through hole 120 (in which case the cable-to-equipment connection is L-shaped), or it can choose to connect the second conductor 500 through the second through hole 130 (in which case the cable-to-equipment connection is through-type). Therefore, it is possible to select the most convenient conductor to connect to the equipment based on actual conditions, thereby reducing cable bending and increasing cable lifespan. This application provides two adapters, a first through hole 120 and a second through hole 130. If wiring is modified later, the adapter can be switched to the other available conductor at any time. Similarly, if a circuit needs to be added later, wiring can be added through the adapter corresponding to the other available conductor. This solves the problem of the limitations of the existing cable terminal structure in wiring modification later, thereby effectively improving the expandability of the cable terminal.

[0047] In one possible implementation, see [link to relevant documentation] Figures 3 to 5 As shown, the adapter 300 is flask-shaped, narrower at the top and wider at the bottom, with an opening on the side of the adapter 300 facing away from the first conductor 400. The three sides of the adapter 300 that connect to the first conductor 400, the second conductor 500, and the conductive assembly 200 are all flat. The flat surface connecting to the first conductor 400 has multiple first screw holes 310, the flat surface connecting to the second conductor 500 has multiple second screw holes 311, and the flat surface connecting to the conductive assembly 200 has multiple third screw holes 312. The first screw holes 310 are for detachable connection to the first conductor 400, the second screw holes 311 are for detachable connection to the second conductor 500, and the third screw holes 312 are for detachable connection to the conductive assembly 200.

[0048] In one possible implementation, see [link to relevant documentation] Figures 6 to 7 As shown, the side of the first conductor 400 that is electrically connected to the adapter 300 has a plurality of second connection holes 241. Bolts are suitable for passing through the first screw hole 310 of the adapter 300 and the second connection holes 241 of the first conductor 400 in sequence, so that the adapter 300 and the first conductor 400 are connected by bolts.

[0049] When assembling the first conductor 400, the side of the first conductor 400 with the second connecting hole 241 is inserted into the cavity 110 of the housing 100 through the first through hole 120, and aligned with the first screw hole 310 on the side of the adapter 300 facing the first through hole 120. A bolt is inserted into the inner cavity of the adapter 300 through the opening, and the bolt is passed through the first screw hole 310 of the adapter 300 and the second connecting hole 241 of the first conductor 400 in sequence, so that the first conductor 400 and the adapter 300 are detachably connected.

[0050] In one possible implementation, see [link to relevant documentation] Figure 7 As shown, the second conductor 500 has multiple third connection holes 242 on the side facing the adapter 300, so that when assembling the second conductor 500, the side of the second conductor 500 with the second connection holes 242 extends into the cavity 110 of the housing 100 through the second through hole 130. The third connection holes 242 of the second conductor 500 are aligned with the second screw holes 311 on the side of the adapter 300 facing the second conductor 500. Then, the bolts are passed through the second screw holes 311 of the adapter 300 and the third connection holes 242 of the second conductor 500 in sequence, so that the second conductor 500 and the adapter 300 are detachably connected.

[0051] In one possible implementation, the second through hole 130 is positioned opposite to the guide hole 140.

[0052] In one possible implementation, the cable terminal of this application further includes a shield 320, which is disposed on the side of the adapter 300. See also... Figure 9 As shown, the shield 320 is circular and matches the larger opening on the side wall of the adapter 300. The shield 320 is fastened to the opening.

[0053] Among them, see Figures 3 to 4 As shown, the adapter 300 has a protrusion at the edge of the opening facing the center of the opening surface, and a fourth screw hole 313 is provided at the protrusion, which is suitable for detachable connection of the shield 320.

[0054] In one possible implementation, see [link to relevant documentation] Figure 10 As shown, the shield 320 has a mounting hole 321, and the mounting hole 321 corresponds one-to-one with the fourth screw hole 313 on the side of the adapter 300 facing the shield 320. Screws are passed through the mounting hole 321 of the shield 320 and the fourth screw hole 313 of the adapter 300 in sequence, so that the shield 320 and the adapter 300 can be detachably connected.

[0055] Also see Figure 1As shown, the adapter 300 has a detachable connecting assembly 200 on the side opposite to the second conductor 500. This allows the cable connector 600 to be connected to the adapter 300 via the connecting assembly 200, and then to conduct electricity to the device via the conductor connected to the adapter 300.

[0056] In one possible implementation, see [link to relevant documentation] Figure 8 As shown, the conductor assembly 200 includes a conductor contact 210 and a third conductor 220. The third conductor 220 is electrically connected to the adapter 300, and the conductor contact 210 is electrically connected to the cable connector 600. The conductor contact 210 has an opening on the side opposite to the cable connector 600, and the opening matches the third conductor 220. The third conductor 220 is suitable for insertion into the opening of the conductor contact 210.

[0057] In one possible implementation, see [link to relevant documentation] Figure 8 As shown, a fourth connecting hole 243 is provided on the side of the third conductor 220 that is electrically connected to the adapter 300. This hole is aligned with a third screw hole 312 on the side of the adapter 300 facing the third conductor 220. A bolt is suitable for passing through the third screw hole 312 and the fourth connecting hole 243 of the third conductor 220 in sequence, thereby achieving a detachable connection between the third conductor 220 and the adapter 300. It should be noted that the third conductor 220 and the second conductor 500 are respectively located on opposite sides of the adapter 300.

[0058] In one possible implementation, the conductor assembly 200 further includes a spring contact finger fixedly disposed between the conductor contact 210 and the third conductor 220. The spring contact finger is adapted to maintain connection pressure stability. The conductor contact 210 has a groove 230 formed along the inner side of its opening edge, and the spring contact finger is disposed within the groove 230.

[0059] Furthermore, in one possible implementation, two spring contacts are provided, and the two spring contacts are stacked. At the same time, two corresponding grooves 230 are also provided, and the two grooves 230 are arranged adjacent to each other.

[0060] When electrically connecting the third conductor 220 to the conductor contact 210, the spring contact finger is first placed in the groove 230 of the conductor contact 210, and then the third conductor 220 is inserted through the opening of the conductor contact 210 so that the spring contact finger presses the third conductor 220 tightly, thereby stably connecting the third conductor 220 to the conductor contact 210.

[0061] In one possible implementation, the conductor assembly 200 further includes a shielding sleeve 250, which is fastened to the side of the cable connector 600 that connects to the conductor contact 210, and the shielding sleeve 250 has screw holes. It should be noted that the conductor contact 210 has a first connection hole 240 on the side facing the cable connector 600, suitable for detachably connecting the shielding sleeve 250.

[0062] In one possible implementation, the screw holes of the shielding sleeve 250 are aligned with the first connection hole 240 of the conductor contact 210, and a bolt is passed through the screw holes of the shielding sleeve 250 and the first connection hole 240 of the conductor contact 210 to make the shielding sleeve 250 and the conductor contact 210 detachably connected. Simultaneously, the shielding sleeve 250 is adapted to the cable connector 600, suitable for fitting the cable connector 600 with the shielding sleeve 250 when the cable connector 600 is inserted into the housing 100 through the guide hole 140, or the shielding sleeve 250 is first connected to the conductor contact 210, then the connected shielding sleeve 250 is fastened onto the cable connector 600, and finally the assembly with the shielding sleeve 250 and the conductor contact 210 is inserted into the housing 100 through the guide hole 140, so that the third conductor 220 is inserted through the opening of the conductor contact 210 to connect the cable connector 600 to the conductor assembly 200.

[0063] It should be noted that the cable connector 600 is electrically connected to the third conductor 220 by the bolts connecting the shielding sleeve 250 and the conductive contact seat 210, so that the cable connector 600 is electrically connected to the adapter 300 by the bolts of the shielding sleeve 250, and then conducts electricity with the equipment through the adapter 300.

[0064] It should also be noted that a fastener 141 is provided on the window of the guide hole 140 to fix it to the cable connector 600 and prevent the cable connector 600 from falling out of the housing 100. The fastener 141 has threaded holes, and the threaded holes of the fastener 141 correspond one-to-one with the threaded holes of the fixing flange 610 of the cable connector 600.

[0065] In one possible implementation, the cable connector 600 is inserted through the guide hole 140, the fastener 141 is engaged with the peripheral protrusion of the cable connector 600, and then the bolt is threaded through the fixing flange 610 and connected to the fastener 141, thereby fixing the cable connector 600 to the housing 100.

[0066] In one possible implementation, the housing 100 also has an inspection hole 150, which is provided on opposite sides of the housing 100 along with the first through hole 120, and a mating flange 151 is fixedly installed on the window of the inspection hole 150. The inspection hole 150 is suitable for disassembly, installation and maintenance of the equipment.

[0067] In one possible implementation, the cable termination structure of this application further includes a flange sealing cover 160, which is detachably connected to the mating flange 151 of the access hole 150. The flange sealing cover 160 has mounting holes along its edge to allow bolts to pass through the mounting holes and the mating flange 151.

[0068] In one possible implementation, the flange cover 160 also includes a sealing ring suitable for ensuring the airtightness of the equipment. The sealing ring is disposed between the flange cover 160 and the mating flange 151. A sealing groove 161 is provided on the inner edge of the flange cover 160 for fixing the sealing ring in place.

[0069] It should be noted that there are two sealing rings, and two corresponding sealing grooves 161 are also provided. The two sealing grooves 161 are set at the same center. Compared with the traditional single-seal design, the double-seal design of this application can effectively improve the airtightness of the equipment.

[0070] Furthermore, when assembling the sealing cover 160, first place the sealing ring in the sealing groove 161, then align the mounting hole of the flange sealing cover 160 with the through hole of the mating flange 151, and use bolts to pass through the mounting hole and the through hole of the mating flange 151 to achieve a detachable connection between the flange sealing cover 160 and the mating flange 151 of the inspection hole 150.

[0071] In one possible implementation, the flange sealing cover 160 further includes a blast-proof plate 170, which is disposed on the side of the flange sealing cover 160 opposite to the access hole 150. The flange sealing cover 160 has screw holes on its surface, and these screw holes correspond one-to-one with the mounting holes of the blast-proof plate 170. The blast-proof plate 170 is mounted on the flange sealing cover 160 by passing bolts through the mounting holes of the blast-proof plate 170 and the screw holes of the flange sealing cover 160.

[0072] In one possible implementation, a flange connection port 700 is also provided on the side wall of the housing 100 to allow connection of other components required by the device.

[0073] In one possible implementation, the housing 100 is made of aluminum.

[0074] Further, see Figures 11 to 12 As shown, this application employs a straight-line arrangement method when laying the three cable terminals for three phases. Arranging the three cable terminals for the three phases along the same axis makes the overall equipment more compact, and the neat straight-line arrangement better conforms to industrial design specifications, thus improving the overall aesthetics of the equipment.

[0075] It should be noted that the traditional triangular arrangement occupies a large space and has significant limitations when the installation environment is restricted. The linear arrangement, on the other hand, effectively reduces the footprint and is suitable for space-constrained installation environments, offering greater versatility. Furthermore, the linear arrangement results in a more compact overall equipment layout, saving on infrastructure costs. Simultaneously, the linear arrangement facilitates easier location and maintenance during inspection. In this application, when the three cable terminal structures are arranged in a linear fashion, their inspection holes 150 are also positioned along the same straight line. Therefore, during problem location, inspection can be performed one by one along the straight line for easy troubleshooting. Maintenance can be performed simply by removing the sealing cover, making maintenance more convenient.

[0076] This application utilizes an adapter 300 to connect conductors in different directions. The housing 100 has through holes corresponding to conductors in different directions, allowing conductors to connect to equipment via these holes, thus connecting the cable connector 600 to the equipment. Therefore, because the adapter 300 simultaneously connects the first conductor 400 and the second conductor 500 in different directions, the cable terminal structure of this application can connect to equipment in different directions simultaneously. Furthermore, since the adapter 300 is detachably connected to conductors in different directions, during specific connections, any conductor can be selected based on the location of the GIS equipment or specific circumstances to connect the cable connector 600 to the equipment. This application provides two adapter interfaces, a first through hole 120 and a second through hole 130. If wiring is modified later, the connection can be easily changed to the adapter interface corresponding to the other unused conductor. Similarly, if additional circuits are needed later, wiring can be added through the adapter interface corresponding to the other unused conductor. This solves the limitation of existing cable terminal structures in later wiring modifications, effectively improving the expandability of the cable terminal.
