Description

Technical Field

[0001] The present invention relates to the technical field of busbar cabinets, and particularly relates to a fixing structure for high-voltage cables in a busbar cabinet. Background Art

[0002] The busbar cabinet is one of the key components of the energy storage system. The core function of the busbar cabinet is to collect the currents of multiple power sources to form one or more larger current outputs for subsequent inversion, grid connection, or direct power supply. In addition, it can effectively manage and protect the battery pack, thereby improving the efficiency and reliability of the system, while reducing the number of cables and simplifying the overall structure.

[0003] In the entire energy storage system, the busbar cabinet only accounts for a part of the whole. Its essence is an integrated power electronic component module in the energy storage system. The connection and fixing part of the high-voltage cable is a very important power electronic component module in the busbar cabinet and is the current collection source of the busbar cabinet.

[0004] The high-voltage cables in the busbar cabinet usually refer to cables with voltages ranging from 10KV to 220KV. They are much thicker and heavier than ordinary cables. Compared with the connection methods of ordinary cables that can be inserted or welded, due to the thick and heavy characteristics of high-voltage cables, a more stable fixing structure is required to ensure that the high-voltage cables can be stably connected and operated when connecting high-voltage cables; and because the power transmission volume of high-voltage cables is large and the voltage is high, once a fault occurs, such as a short circuit or overload, the arc leaking from the cable will instantly penetrate the busbar cabinet, resulting in serious consequences such as electric leakage, equipment damage, and fire. Therefore, it is also urgently needed to ensure that the high-voltage cables will not cause major disasters during a fault. Summary of the Invention

[0018] In the above technical solution, the beneficial effects of a fixing structure for high-voltage cables in a busbar cabinet provided by the present invention are as follows:

[0019] The present invention docks the mounting cylinder sliding on the busbar connector with the embedding sleeve connected to the cable connector.

Detailed implementation manners

[0039] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0040] Please refer to Figure 1 - Figure 14 , a fixing structure for high-voltage cables in a busbar cabinet, including a busbar joint 200 and a cable joint 500 docked with the busbar joint 200. An installation groove 203 is provided on the surface of the busbar joint 200. One end of the busbar joint 200 is slidably sleeved with an installation cylinder 204. One end inside the installation cylinder 204 is connected with an elastic clamping strip 205. The elastic clamping strip 205 is slidably matched with the installation groove 203. One end of the cable joint 500 is provided with an embedding sleeve 502. The embedding sleeve 502 is docked with the installation cylinder 204. A fixing groove 504 is provided inside the docking end of the embedding sleeve 502. A converging ring 503 is provided in the middle section of the embedding sleeve 502;

[0041] The inside of the busbar joint 200 is provided with a fixing component. A transmission component is connected between the installation cylinder 204 and the fixing component. The transmission component is arranged inside the busbar joint 200. The inside of the converging ring 503 is provided with an insulating component. When the cable joint 500 is inserted into the busbar joint 200, it drives the embedded sleeve 502 to push the installation cylinder 204 to slide inward, triggering the movement of the transmission component, thereby driving the fixing component to open and engage with the fixing groove 504, and simultaneously driving the insulating component to expand. When a high-voltage cable fails, it triggers the fixing component to fuse, automatically releasing the cable joint 500 while passively converging the insulating component.

[0042] In the present invention, the installation cylinder 204 sliding on the busbar joint 200 is docked with the embedded sleeve 502 connected to the cable joint 500. When the cable joint 500 is inserted into the busbar joint 200, it drives the embedded sleeve 502 to push the installation cylinder 204 to slide inward, triggering the movement of the transmission component, thereby driving the fixing component to open and engage with the fixing groove 504, and simultaneously driving the insulating component to expand, so that the cable joint 500 is passively fixed on the busbar joint 200. When a high-voltage cable fails, it triggers the fixing component to fuse, automatically releasing the cable joint 500 while passively converging the insulating component, insulating and sealing the cable joint 500 so that no high voltage is released, thereby protecting the busbar cabinet from being broken down by current or causing a fire or electric leakage.

[0043] Further, both the installation groove 203 and the elastic clamping strip 205 are horizontally arranged "L"-shaped groove structures, and the longer part of the installation groove 203 is inside the busbar joint 200.

[0044] Specifically, when the installation cylinder 204 slides, it drives the elastic clamping strip 205 to slide in the installation groove 203, so that the protruding end of the elastic clamping strip 205 is clamped into the shorter part of the installation groove 203, locking the installation cylinder 204 and preventing it from moving further.

[0045] Furthermore, to disassemble the high-voltage cable, just press the elastic clamping strip 205 so that it no longer clamps the installation cylinder 204, and then pull out the cable joint 500 to separate the cable joint 500 from the busbar joint 200.

[0046] In an embodiment further provided by the present invention, the transmission component includes a first connection seat 300 connected inside the installation cylinder 204. One end of the first connection seat 300 is rotatably connected to a first transmission bar 301. The upper surface of the other end of the first transmission bar 301 is connected to a transmission shaft 305. The lower surface of the other end of the first transmission bar 301 is rotatably connected to a second transmission bar 303. A limiting track groove 302 is provided inside the busbar joint 200. The transmission shaft 305 is slidably matched with the limiting track groove 302. One end of the second transmission bar 303 is rotatably connected to a second connection seat 304.

[0047] Further, the first connecting seat 300, the first transmission bar 301, the limiting track groove 302, the second transmission bar 303, the second connecting seat 304, and the transmission shaft 305 are all located inside the busbar joint 200.

[0048] Furthermore, the first connecting seat 300 drives the first transmission bar 301 to rotate, the second connecting seat 304 cooperates with the second transmission bar 303 to rotate, and the limiting track groove 302 is used to limit the movement track of the second transmission bar 303.

[0049] Specifically, when the mounting cylinder 204 slides, it drives the first transmission bar 301 to rotate, thereby driving the second transmission bar 303 to rotate, and under the action of the limiting track groove 302, it drives the second connecting seat 304 to slide.

[0050] In an embodiment further provided by the present invention, a sliding hole 201 and a mating groove 202 are provided inside the busbar joint 200. A fusing rod 402 is slidably connected inside the sliding hole 201. The inner end of the fusing rod 402 is connected to one end of the second connecting seat 304. One end of the fusing rod 402 is connected to a transmission rod 400, and a first transmission groove 401 is provided in the middle of the transmission rod 400.

[0051] Further, the material of the fusing rod 402 is a material with a relatively low melting point such as lead-tin alloy or silver-copper alloy. When the high-voltage cable is short-circuited or overloaded, a large amount of heat is generated, causing the fusing rod 402 to fuse.

[0052] In an embodiment further provided by the present invention, the fixing assembly includes a transmission member 403 rotatably connected inside the first transmission groove 401. A second transmission groove 404 is provided on the transmission member 403. A first locking member 405 is rotatably connected inside the second transmission groove 404. A transmission plate 408 is connected to the surface of the first locking member 405. A second locking member 406 is connected to the outer end of the transmission plate 408. A mating member 407 is connected to the upper end of the transmission plate 408. The mating member 407 is rotatably connected to the mating groove 202, and the transmission plate 408 is disposed inside the mating groove 202.

[0053] Further, there are two first locking members 405, two second locking members 406, two mating members 407, and two transmission plates 408, and they are mirror-symmetrical about the center point of the transmission member 403.

[0054] Furthermore, the shapes of the two first locking members 405 are both circular blocks with a part missing. The missing parts of the two first locking members 405 abut against each other and mesh with each other.

[0055] Specifically, when the second connecting seat 304 slides, it drives the fusing rod 402 to slide outward together in the sliding hole 201, thereby driving the transmission rod 400 to slide, causing the transmission member 403 to rotate, driving the first locking member 405 to rotate, and driving the cooperating member 407 to rotate. Under the rotational action of the cooperating member 407, the transmission plate 408 is opened, and the second locking member 406 abuts against the inner wall of the fixing groove 504.

[0056] In an embodiment further provided by the present invention, the insulating assembly includes two converging gear rings 604 rotatably connected inside the converging ring 503, and a transmission gear 605 is also rotatably connected inside the converging ring 503. Both converging gear rings 604 are engaged with the transmission gear 605. A second converging shaft 603 is rotatably connected between the two converging gear rings 604. A converging strip 602 is connected to the surface of the second converging shaft 603. One end of one of the converging gear rings 604 is rotatably connected to a first converging shaft 601. An insulating sealing plate 600 is connected to the surface of the first converging shaft 601, and one end of the first converging shaft 601 is rotatably connected to one end of the insulating sealing plate 600.

[0057] Further, there are five insulating sealing plates 600, first converging shafts 601, converging strips 602, and second converging shafts 603, and they are arranged in an annular equidistant array around the center point of the converging ring 503.

[0058] Furthermore, the rotational action of the first converging shaft 601 is used to limit the rotational trajectory of the insulating sealing plate 600.

[0059] Specifically, when the transmission gear 605 rotates, it drives the two converging gear rings 604 to rotate, thereby driving the converging strip 602 to rotate, driving the insulating sealing plate 600 to rotate, and causing the insulating sealing plate 600 to unfold into the converging ring 503.

[0060] In an embodiment further provided by the present invention, the converging ring 503 is provided with a circular hole, and an outer tube 606 is rotatably connected in the circular hole. One end of the outer tube 606 is connected to one end of the transmission gear 605. An inner tube 608 is slidably sleeved inside the outer tube 606. A spiral groove 607 is provided on the surface of the outer tube 606. A converging member 609 is connected to the surface of the inner tube 608, and the converging member 609 is slidably engaged with the spiral groove 607.

[0061] Further, a return spring is connected between the inner tube 608 and the transmission gear 605.

[0062] In an embodiment further provided by the present invention, a fixing plate 207 is fixedly connected to the surface of the busbar joint 200. One end of the fixing plate 207 is connected to a converging rod 208, and the converging rod 208 is slidably engaged with the outer tube 606.

[0063] Specifically, when the embedded sleeve 502 is docked, the focusing rod 208 enters the outer tube 606, abuts against one end of the inner tube 608, and drives the inner tube 608 to slide inward in the outer tube 606, thereby driving the focusing member 609 to slide on the spiral groove 607, causing the outer tube 606 to rotate, thereby driving the transmission gear 605 to rotate.

[0064] In an embodiment further provided by the present invention, one end of the cable connector 500 is connected to a waterproof sheath 701, a cable body 700 is disposed inside the waterproof sheath 701, and a shielding sleeve 704, an insulating sleeve 703, a shock-absorbing sleeve 702 and an inner conductor 705 are sequentially disposed inside the cable body 700 from the outside to the inside.

[0065] In an embodiment further provided by the present invention, a power transmission pole 501 is provided inside the cable connector 500, one end of the power transmission pole 501 is connected to one end of the cable body 700, and a power connection pole 206 is provided inside the bus connector 200, and the power transmission pole 501 and the power connection pole 206 are slidably matched.

[0066] Furthermore, in the initial state, the insulating sealing plates 600 are folded and merged together to insulate and seal the power transmission pole 501 , and when unfolded, the power transmission pole 501 is exposed so as to dock with the power connection pole 206 .

[0067] In an embodiment further provided by the present invention, one end of the bus connector 200 is connected to the bus bar 100 , and one side surface of the bus bar 100 is connected to the bus seat 101 .

[0068] Furthermore, the other end of the junction connector 200 is installed in a junction cabinet.

[0069] In the present invention, first, the cable connector 500 is aligned with the bus connector 200 and inserted. The embedding sleeve 502 pushes the mounting cylinder 204 to slide inward, and the bundling rod 208 is butted against the outer tube 606 and enters the inside of the outer tube 606. When the mounting cylinder 204 slides inward, it drives the elastic latch 205 to slide in the mounting groove 203, so that the protruding end of the elastic latch 205 is snapped into the shorter part of the mounting groove 203, locking the mounting cylinder 204 and preventing it from moving further; Synchronously, when the mounting cylinder 204 slides, it also drives the first transmission bar 301 to rotate, thereby driving the second transmission bar 303 to rotate. Under the action of the limiting track groove 302, the second connecting seat 304 is driven to slide. When the second connecting seat 304 slides, it drives the fusing rod 402 to slide outward together in the sliding hole 201, thereby driving the transmission rod 400 to slide, causing the transmission member 403 to rotate, driving the first locking member 405 to rotate, and driving the mating member 407 to rotate. Under the rotational action of the mating member 407, the transmission plate 408 is opened, and the second locking member 406 abuts against the inner wall of the fixing groove 504, thereby passively fixing the cable connector 500 on the bus connector 200; Synchronously, during docking, the bundling rod 208 enters the inside of the outer tube 606, abuts against one end of the inner tube 608, and drives the inner tube 608 to slide inward in the outer tube 606, thereby driving the bundling member 609 to slide on the spiral groove 607, causing the outer tube 606 to rotate, driving the transmission gear 605 to rotate. When the transmission gear 605 rotates, it drives the two bundling gear rings 604 to rotate, thereby driving the bundling strip 602 to rotate, driving the insulating sealing plate 600 to rotate, and unfolding the insulating sealing plate 600 into the bundling ring 503, so that the power transmission column 501 is exposed, enabling the power transmission column 501 to be docked with the power connection column 206, and the circuit is connected to complete the installation and power-on; When a high-voltage cable is short-circuited or overloaded, a large amount of heat is generated, causing the fusing rod 402 to fuse. As a result, the transmission plate 408 no longer opens, the second locking member 406 no longer locks the fixing groove 504, the cable connector 500 drops off, and the bundling rod 208 disengages from the outer tube 606. Under the action of the return spring, the insulating sealing plate 600 rotates and resets, insulating and sealing the power transmission column 501 again, insulating and sealing the cable connector 500, and preventing the release of high-voltage electricity, thereby protecting the busbar cabinet from being punctured by current or causing a fire or electric leakage.

[0070] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
