Description

Technical Field

[0001] This invention relates to power transmission, and more particularly to an AC / DC emergency bus system. Background Technology

[0002] When the power grid is online, low-voltage users need to be supplied with power via ground or overhead lines. Furthermore, due to the existence of different types of power consumption, such as renewable energy sources, virtual power plants, and line faults, multi-functional temporary power supply lines are required, including AC / DC hybrid power supply. However, laying cables on the ground is unsafe and cannot be used long-term. In addition, in some special areas and situations, a silent, mobile, and reliable power source is needed to address immediate emergency power needs, but traditional generator power points are often located far from the user end.

[0003] Existing technology discloses a modular outdoor low-voltage movable busbar system. An epoxy busbar has fixed mounting terminals, and one or more epoxy busbar mounting terminals are interconnected and fixed to the ground. A power access box is connected to either the power supply end or the power consumption end via a cable. One end of the epoxy busbar is introduced into the power access box and connected to the cable, while the other end is introduced into a top-mounted cable tray box. An overhead cable is installed on a lifting busbar support, with one end introduced into the top-mounted cable tray box and connected to the epoxy busbar. When the power access box is connected to the power supply end, the other end of the overhead cable is connected to the power consumption end; conversely, when the power access box is connected to the power consumption end, the other end of the overhead cable is connected to the power supply end. This existing technology provides effective and reliable power supply in emergency and temporary power supply scenarios, and is suitable for different terrains and environments. The cable height is adjustable to adapt to different height requirements, ensuring balanced support. However, this existing technology cannot provide power for multiple different power consumption modes.

[0004] In summary, the technical problem that needs to be solved is how to design a mobile bus system that can provide power in multiple different ways. Summary of the Invention

[0006] The objective of this invention can be achieved through the following technical solutions.

[0007] According to one aspect of the present invention, an AC / DC emergency busbar system is provided, comprising a power transfer box, an epoxy busbar, power supply cables, and a lifting busbar support. The power transfer box is connected to a power supply, and the epoxy busbar connects the power transfer box and the power supply cables. Multiple epoxy busbars are sequentially connected by bonding, and the power supply cables are mounted on the lifting busbar support. The epoxy busbar includes positive and negative aluminum busbars for DC and three-phase aluminum busbars for AC, which are coated with epoxy resin; the power supply cable includes a DC power supply cable and an AC power supply cable, with the positive and negative aluminum busbars for DC connected to the DC power supply cable and the three-phase aluminum busbars for AC connected to the AC power supply cable.

[0009] As a preferred technical solution, the power supply includes a DC power supply and an AC power supply. After the DC power supply is connected to the DC circuit breaker, it is divided into two parallel paths. One path is connected to the positive and negative aluminum busbars for DC power supply, and the other path is connected to the inverter and connected in parallel with the three-phase aluminum busbars for AC power supply. After the AC power supply is connected to the AC circuit breaker, it is divided into two parallel paths. One path is connected to the three-phase aluminum busbar for AC, and the other path is connected to the rectifier module and connected in parallel with the positive and negative aluminum busbars for DC.

[0010] As a preferred technical solution, one end of the DC positive and negative aluminum busbar and the AC three-phase aluminum busbar is equipped with a quick-connect AC / DC cable connector, which is connected to the power adapter box through the quick-connect AC / DC cable connector.

[0011] As a preferred technical solution, the DC power supply is connected to the power transfer box via a hollow copper conductive busbar, the DC positive and negative aluminum busbars are connected to a hanging DC switch, and the AC three-phase aluminum busbars are connected to a hanging three-phase AC switch.

[0012] As a preferred technical solution, the busbar system also includes a modular cable trench made of glass fiber reinforced concrete, which is arranged on one side of the power transfer box, and the epoxy busbar is arranged inside the modular cable trench.

[0013] As a preferred technical solution, the epoxy busbar is provided with a branch power output port in the middle. The branch power output port includes a copper nut. One end of the copper nut is connected to the positive and negative aluminum busbars for DC or the three-phase aluminum busbars for AC, and the other end is equipped with a waterproof insulating cover and is covered with epoxy resin on the side.

[0014] As a preferred technical solution, the lifting busbar support includes a support rod, a base plate, an epoxy busbar connection and fixing pipe, a lifting device, wheels, and a lightning rod; the support rod is vertically fixed on the base plate, the epoxy busbar connection and fixing pipe is fixedly installed on the support rod, the epoxy busbar is connected to the epoxy busbar connection and fixing pipe, and the power supply cable is hung on the lifting device; the lightning rod is fixed to the top of the support rod. The lifting busbar support includes a fixed state and a moving state. When the lifting busbar support is in the moving state, the wheels are fixed to the base plate; when the lifting busbar support is in the fixed state, the base plate is fixed to the ground.

[0015] As a preferred technical solution, the epoxy busbar connection fixing pipe is connected to the epoxy busbar via rollers.

[0016] As a preferred technical solution, the epoxy busbar is provided with multiple fixed support points.

[0017] Compared with the prior art, the present invention has the following beneficial effects.

[0018] 1) This invention achieves unified management and flexible output of both AC and DC power supplies. The epoxy busbar integrates the positive and negative aluminum busbars for DC and the three-phase aluminum busbars for AC with epoxy resin, providing excellent insulation, water resistance, and mechanical strength, making it suitable for complex outdoor emergency power supply scenarios. Multiple epoxy busbars are connected sequentially by bonding, allowing for flexible extension according to the actual power supply distance, significantly improving the system's modularity and rapid deployment capability. Power cables are classified and set up according to AC and DC, ensuring no interference between them and guaranteeing power supply accuracy and safety. The whole system constitutes a convenient and reliable AC / DC emergency busbar system.

[0019] 2) This invention features two types of epoxy busbars: Type I and Type L, which can be flexibly combined to adapt to different laying requirements. Type I epoxy busbars are suitable for horizontal laying in straight sections, while Type L epoxy busbars can be used for wiring at corners or in vertical directions. Using both together allows the system to freely switch between horizontal ground-level laying and overhead three-dimensional laying modes, significantly expanding the system's application scenarios and meeting the complex wiring requirements of different sites. The DC positive and negative aluminum busbars and the AC three-phase aluminum busbars have copper bonding layers at both ends. Using aluminum busbars effectively reduces the overall weight of the epoxy busbar, while the copper bonding layers at both ends, connecting the two epoxy busbars through bonding, greatly reduces contact resistance.

[0020] 3) The DC power supply and AC power supply of this invention are connected to the corresponding busbars through mutual backup lines. At the same time, an inverter and a rectifier module are introduced to enable bidirectional conversion and complementarity between the DC system and the AC system. When the power supply on one side fails or is interrupted, the power supply on the other side can maintain continuous power supply to the load through the conversion channel, which significantly improves the power supply reliability and fault tolerance of the system, and adapts to the needs of diversified power supply scenarios such as new energy access and virtual power plants.

[0021] 4) This invention features a quick-connect AC / DC cable interface, making the connection between the epoxy busbar and the power transfer box simpler and faster, significantly reducing on-site installation time and improving the rapid response capability of emergency power supply. The DC power supply uses a hollow copper conductive busbar connected to the power transfer box, providing excellent current carrying capacity. The design of the hanging DC switch and the hanging three-phase AC switch allows for flexible mounting on the busbar, facilitating easy installation, disassembly, and maintenance. The modular cable trench made of glass fiber reinforced concrete has the advantages of high strength, corrosion resistance, and light weight, making it suitable for rapid outdoor installation.

[0022] 5) This invention features a branch power output port in the middle of the epoxy busbar, enabling simultaneous power supply to multiple load points without interrupting the main busbar operation, thus meeting the needs of distributed power supply from multiple power sources. A waterproof insulating cover is installed at the end of the copper nut, and the sides are further covered with epoxy resin, ensuring the overall waterproof and insulating performance of the branch output port location.

[0023] 6) The lifting busbar support of this invention has two working modes: fixed state and mobile state, which can adapt to the rapid deployment needs of different working positions; the epoxy busbar connection fixing pipe reliably constrains the position of the epoxy busbar, and the lifting equipment can adjust the erection height of the power supply cable according to the site requirements; the top of the support rod is equipped with a lightning rod to provide effective lightning protection in the overhead power supply mode.

[0024] 7) The epoxy busbar connection fixing pipe of this invention connects to the epoxy busbar via rollers. The unidirectional guide rail structure ensures the uniqueness of the installation direction, and the guide rail connection is convenient to operate. Multiple fixed support points are set on the epoxy busbar, which, through connection with external support structures, effectively share the self-weight and external load of the busbar during long-distance laying, preventing bending deformation of the busbar due to excessive span, maintaining the stability of the busbar, and improving the overall mechanical strength and resistance to external impact of the system.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0034] Example 1 like Figure 1 and Figure 2 As shown, this embodiment provides an AC / DC emergency busbar system, including a power transfer box 1, an epoxy busbar 2, power supply cables 3, and a lifting busbar support 4. The power transfer box 1 is connected to the power supply. This invention can realize multi-purpose and multi-scenario power supply modes, making the power supply method more standardized and reliable.

[0035] like Figure 3 and Figure 4As shown, the power transfer box 1 serves as the central hub for AC and DC power supply access and distribution. The box contains both AC and DC circuit breakers for independent protection and control of the connected AC and DC power supplies. After being connected via the DC circuit breaker, the DC power supply is divided into two parallel paths: one directly connects to the positive and negative aluminum busbars for DC power, and the other connects to the inverter and is connected in parallel with the three-phase aluminum busbar 24 for AC power, thus achieving DC-to-AC conversion. Similarly, after being connected via the AC circuit breaker, the AC power supply is also divided into two parallel paths: one directly connects to the three-phase aluminum busbar 24 for AC power, and the other, after being processed by the rectifier module, is connected in parallel with the positive and negative aluminum busbars for DC power, achieving AC-to-DC conversion. This circuit design creates a bidirectional backup relationship between the AC and DC systems, ensuring continuous power supply even if either side experiences a power outage. The DC power supply is connected to the power transfer box 1 via a hollow copper conductive busbar 7, which combines excellent conductivity with lightweight construction, facilitating rapid on-site installation and relocation.

[0036] The output side of the power adapter box 1 is connected to the epoxy busbar 2 via quick-connect AC / DC cable connectors. These quick-connect connectors are installed at the ends of the DC positive and negative aluminum busbars and the AC three-phase aluminum busbar 24. Using a plug-in structure, a reliable electrical connection is formed simply by inserting the corresponding cable or busbar into the connector, eliminating the need for tools and complex wiring, significantly reducing on-site installation time. The epoxy busbar 2 is connected via the miniaturized power adapter box 1, which occupies a small area, is easy to fix, and improves the overall waterproof performance of the system, meeting the requirements of outdoor environments.

[0037] The epoxy busbar 2 internally integrates both DC positive and negative aluminum busbars and AC three-phase aluminum busbars 24. The aluminum wires are lightweight, and insulation spacing is maintained between each conductor. The entire assembly is uniformly coated with epoxy resin 25 using a vacuum casting process, forming a dense insulating protective layer. This provides excellent waterproofing, insulation, and impact resistance, meeting the stringent environmental requirements for long-term outdoor use and replacing non-standard temporary wiring and other unregulated power supply methods. The epoxy busbar 2 is available in two specifications based on its form: Type I epoxy busbar 21 and Type L epoxy busbar 22. Figure 5 As shown, Type I epoxy busbar 21 is used for horizontal or vertical laying in a straight direction, while Type L epoxy busbar 22 is used at corner positions or sections where the laying direction needs to be changed. The two are modularly spliced ​​and extended through bonding. The epoxy busbar 2, through modular combinations of different types (L-shaped and Type I), can adapt to power supply at different heights during overhead power supply; and it is effectively fixed with the lifting cable support, forming a remote power supply mode combining a frame and cables. Figure 7As shown, the copper bonding layer 5 is located at the connection point of two adjacent busbar sections. Its connection end face is bonded (copper powder is sprayed at three times the speed of sound onto both ends of the DC positive and negative aluminum busbars and the AC three-phase aluminum busbar 24). Using aluminum busbars effectively reduces the overall weight of the epoxy busbar 2, while the copper bonding layer 5 at both ends, connecting the two epoxy busbars 2 through bonding, greatly reduces contact resistance, allowing for the passage of large currents without significant temperature rise. Simultaneously, the connection area is covered with a flexible sealing layer 6, ensuring that the waterproof and insulation performance of the entire busbar system is not weakened by splicing. In the case of multiple epoxy busbar sections 2 combined and laid, the system can flexibly increase or decrease the number of modules according to the on-site power supply distance, exhibiting strong scalability.

[0038] The positive and negative aluminum busbars for DC use are equipped with hanging DC switches, and the three-phase aluminum busbars for AC use are equipped with hanging three-phase AC switches. Both types of switches are installed by hanging, which allows for the flexible addition or removal of branch protection switches without disconnecting the main busbar body, making it convenient to flexibly configure the power supply circuit according to the distribution of load points on site.

[0039] In the middle of epoxy busbar 2, branch power output ports are set according to the load distribution requirements. Copper nuts are embedded in the branch output ports. One end of the copper nut is directly connected to the DC positive and negative aluminum busbars or the AC three-phase aluminum busbar 24 inside the busbar, achieving low-impedance electrical connection. The other end is equipped with a waterproof insulating cover to prevent the intrusion of external moisture, dust, and other foreign objects. The side of the interface is further covered with epoxy resin 25, maintaining continuity of the protective layer with the main body of the busbar. This ensures that the waterproof and insulation performance of the entire busbar system is not affected while achieving multi-point branch power supply. By setting multiple branch output ports at intervals along the middle of the busbar, the power supply needs of multiple load points can be met simultaneously without the need for laying a separate main line.

[0040] The epoxy busbar 2 is also equipped with multiple fixed support points along the route. These fixed support points are connected to external support structures or ground fixing components to effectively constrain the position of the busbar, prevent the busbar from bending and deforming due to its own weight during long-distance laying, maintain the regularity of the overall laying path, withstand occasional collision loads from the outside, and extend the service life of the busbar.

[0041] When using ground-based cable laying, a modular cable trench made of fiberglass reinforced concrete can be laid along one side of the power transfer box 1. The epoxy busbar 2 can be placed inside the trench for protection, preventing damage from vehicles or people, while maintaining a clean surface and safe passage. The modular fiberglass reinforced concrete trench can be assembled and extended as needed to adapt to different power supply distances required for on-site laying.

[0042] The power supply cable 3 is installed on the lifting busbar support 4. The power supply cable 3 is divided into two types: DC power supply cable 30 and AC power supply cable 31, which correspond to the output terminals of the DC positive and negative aluminum busbars and the AC three-phase aluminum busbars 24, respectively. The power is distributed from the busbar system to each power load point through the cable, realizing the final distribution and supply of AC and DC power.

[0043] Example 2 This embodiment provides an AC / DC emergency busbar system, including a power transfer box 1, an epoxy busbar 2, power supply cables 3, and a lifting busbar support 4. The power transfer box 1 is connected to a power supply. Compared with embodiment 1, the lifting busbar support 4 further includes a support rod 40, a base plate 41, an epoxy busbar connection fixing pipe 42, a lifting device 43, wheels 44, and a lightning rod 45. The support rod 40 is vertically fixed on the base plate 41, forming the vertical load-bearing frame of the entire support. The base plate 41 is a wide rectangular plate, providing sufficient support area to ensure the stability of the support in a fixed state.

[0044] like Figure 6 As shown, in the mobile state, wheels 44 are fixedly installed under the base plate 41, allowing operators to move the entire support freely around the construction site for quick positioning or relocation without the need for lifting equipment. Wheels 44 can bear the combined weight of the support body and the installed busbars and cables, moving flexibly on flat ground and adapting to various outdoor construction environments. After determining the installation position, wheels 44 are locked or removed, and the base plate 41 is directly fixed to the ground, putting the support into a fixed state. The fixing method can use expansion bolts or anchor bolts to firmly connect the base plate 41 to the ground. The fixed support has good resistance to lateral loads, remaining stable and not overturning under the tension of the power supply cable 3, wind loads, and other external forces.

[0045] The epoxy busbar connection and fixing pipe 42 is installed and fixed on the support rod 40 to reliably fix the epoxy busbar 2 at a specific height position on the bracket. The epoxy busbar connection and fixing pipe 42 is connected to the epoxy busbar 2 via rollers. This guide rail interface adopts a one-way locking design. The epoxy busbar 2 is fixed by pushing it into the guide rail in a specific direction. The interface structure restricts the uniqueness of the installation direction, preventing operators from installing in the wrong direction and fundamentally avoiding the risk of incorrect installation. At the same time, the guide rail fixing method prevents the epoxy busbar 2 from easily coming out when subjected to axial external force, ensuring a firm and reliable connection and significantly improving the mechanical strength of the connection between the busbar and the bracket. If it is necessary to adjust the installation height of the epoxy busbar 2 or disassemble it for maintenance, it can be quickly unlocked by simply operating in the reverse direction of the guide rail without the need for tools to disassemble the fasteners, which is convenient and quick.

[0046] The power supply cable 3 is suspended on the lifting device 43, which is mounted on the support rod 40. The vertical height of the power supply cable 3 can be adjusted. By operating the lifting device 43, the power supply cable 3 can be raised to the required height to meet the overhead height requirements in different situations. For example, in areas where vehicles or pedestrians need to pass, the cable can be raised above a safe height to ensure passage safety; in more open areas, the cable height can be lowered to reduce cable tension and wind load. Multiple lifting busbar supports 4 can work together to form a continuous overhead cable channel over a large area, enabling long-distance overhead power supply.

[0047] Lightning rod 45 is fixed to the top of support rod 40, which is the highest point in the entire support structure. When the system is powered by overhead power, the overhead cables and the support itself are easy targets for lightning strikes. Lightning rod 45 effectively protects the overhead cables and connected equipment from lightning damage by guiding the lightning current to the ground, providing reliable lightning protection for the entire overhead power supply system. This is especially important in application scenarios with high lightning risk, such as in the field or open areas.

[0048] The lifting busbar support 4 adopts a modular configuration concept. Multiple lifting busbar supports 4 can be added to form a complete overhead power supply system based on the on-site power supply distance and line routing. The spacing between multiple supports is rationally determined according to the sag requirements of the power supply cables 3. The epoxy busbars 2 are segmented and fixed to each support via epoxy busbar connection fixing pipes 42. Combined with the combination of type I epoxy busbars 21 and type L epoxy busbars 22, a three-dimensional overhead power supply line with both horizontal and vertical corner sections can be formed, meeting the overhead power supply needs in complex terrain environments. The entire lifting busbar support 4 system has the capability to simultaneously erect AC and DC busbars. DC power cables 30 and AC power cables 31 are arranged in separate zones on the upper and lower levels, with clear cable layers and no crossings, ensuring the safe and reliable operation of both AC and DC power supplies under overhead power supply conditions.

[0049] This invention enables rapid switching between different power supply modes, including horizontal and overhead power. Overhead power supply is more flexible and adaptable, allowing for long-distance power transmission. It facilitates rapid connection between the power supply end and the user end, and is not limited by the incoming lines or power supply methods at the power supply and user ends. It allows for rapid installation and power supply, improving the safety and reliability of power grid equipment. It also enables remote monitoring of operating status and remote silent emergency power supply, eliminating noise pollution from mobile generators in residential areas and other special environments during emergency power supply. It provides effective and reliable power supply in both emergency and temporary power supply scenarios. This invention can be applied to temporary power supply at low-voltage user ends, and can also connect power to the power supply end in the new energy field, achieving bidirectional application.

[0050] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
