[0051] In new energy ships, the power system is the core of the new energy ship power system. The power system includes a high-voltage busbar system and a low-voltage control system. The high-voltage busbar system consists of multiple independently arranged high-voltage boxes, and each high-voltage box contains a set of battery clusters. The low-voltage control system is a low-voltage box. The multiple high-voltage boxes and the low-voltage box are independent of each other. The multiple high-voltage boxes are connected by wire harnesses and are also connected to the low-voltage box through wire harnesses. However, the space occupied by such multiple independently arranged high-voltage boxes and low-voltage boxes is too large, and the space conditions in the ship's cabins are limited, unable to accommodate the independently arranged high-voltage boxes and low-voltage boxes, and unable to meet the actual installation requirements.

[0052] To solve the above problems, as Figures 1 to 4 shown, this embodiment provides a marine busbar cabinet. The marine busbar cabinet includes a cabinet body 100, a low-voltage control system 200, a high-voltage busbar system 300, and an insulation isolation structure 400. Among them, the high-voltage busbar system 300 includes at least two battery clusters connected in series and / or in parallel. The low-voltage control system 200 is electrically connected to the battery clusters. The cabinet body 100 has a receiving cavity 111 for accommodating the low-voltage control system 200 and the high-voltage busbar system 300. The insulation isolation structure 400 is arranged in the receiving cavity 111. The insulation isolation structure 400 can split the receiving cavity 111 into a mutually insulated low-voltage chamber 1 and a high-voltage chamber 2. The low-voltage control system 200 is arranged in the low-voltage chamber 1, and the high-voltage busbar system 300 is arranged in the high-voltage chamber 2.

[0053] This marine busbar cabinet realizes the integrated accommodation of the low-voltage control system 200 and the high-voltage busbar system 300 by arranging a receiving cavity 111 for accommodating the low-voltage control system 200 and the high-voltage busbar system 300 in the cabinet body 100, using the insulation isolation structure 400 to split the receiving cavity 111 into a mutually insulated low-voltage chamber 1 and a high-voltage chamber 2, arranging the low-voltage control system 200 in the low-voltage chamber 1, and arranging the high-voltage busbar system 300 in the high-voltage chamber 2. This not only ensures the use safety, but also has a compact structure, effectively saves the installation space, and meets the actual installation requirements. In addition, by ensuring that the high-voltage busbar system 300 includes at least two battery clusters connected in series and / or in parallel, the high-voltage busbar system 300 can output stable and qualified electricity to meet the actual power consumption requirements of the ship.

[0054] It should be noted that in this embodiment, the high-voltage busbar system 300 includes five battery clusters connected in parallel with each other. The maximum current of each battery cluster does not exceed 140A, and the low-voltage control system 200 can independently control the charging and discharging of each battery cluster. In other embodiments, on the premise of ensuring safety, the specific number of battery clusters in the high-voltage busbar system 300 and the maximum current value of each battery cluster can be adjusted according to actual needs, as long as it is ensured that the low-voltage control system 200 can independently control the charging and discharging of the battery clusters. This embodiment does not make specific limitations. It should be noted that in this embodiment, the length of each group of battery clusters is 639mm, the width is 381mm, and the height is 1470mm. In other embodiments, the specific specifications of the battery clusters can also be adjusted according to actual power consumption requirements, and the specific specifications of the cabinet 100 can be adjusted accordingly, so that the cabinet 100 can integrate the low-voltage control system 200 and the high-voltage busbar system 300.

[0055] Specifically, the busbar in the high-voltage busbar system 300 is a copper busbar, and the thickness of the copper busbar is 6mm. The length and width of the copper busbar are 50mm respectively, and the copper busbar has an overcurrent capacity of 800A to ensure the busbar safety of the battery clusters. In addition, the electrical clearance between the copper busbar in the high-voltage busbar system 300 and the external conductive part is not less than 30mm to further improve the use safety of the marine busbar cabinet.

[0056] As Figure 2 shown, in this embodiment, the low-voltage control system 200 includes a control switch 210, a battery management system 220, and a switching power supply 230. Among them, the switching power supply 230 is used to switch the type of output voltage of the battery cluster. The battery management system 220 and the switching power supply 230 are respectively arranged on both sides of the cabinet 100. The battery management system 220 is connected to each group of battery clusters by wire harnesses. The battery management system 220 can detect the voltage information and current information of each group of battery clusters in real time. Each group of battery clusters is connected by output wire harnesses through the control switch 210, and the control switch 210 is used to control the conduction and disconnection between the battery cluster and the output line. It should be noted that in this embodiment, the switching power supply 230 includes a DC / DC power supply and an AC / DC power supply. The specific structures and working principles of the DC / DC power supply, the AC / DC power supply, the control switch 210, and the battery management system 220 all belong to the prior art and will not be elaborated here.

[0057] In this embodiment, the high-voltage busbar system 300 further includes a fuse 310 and a relay 320. The relay 320 and the fuse 310 are both connected to the battery cluster by wire harnesses. By setting the relay 320, the low-voltage control system 200 can control the high-voltage busbar system 300, and by setting the fuse 310, the output of the high-voltage busbar system 300 can be cut off to ensure the use safety.

[0058] As an alternative, the cabinet body 100 includes a main body 110 and a door body 120. Among them, the main body 110 has a receiving cavity 111, and the receiving cavity 111 is provided with an opening. The insulation isolation structure 400 can enter the receiving cavity 111 along the opening, and the door body 120 is connected to the main body 110 and seals the opening. By setting the cabinet body 100 as the main body 110 with the receiving cavity 111 and providing an opening in the receiving cavity 111, it is convenient for the disassembly and assembly of the insulation isolation structure 400. And by setting the door body 120 to be connected to the main body 110 to seal the opening, the protection of the low-voltage control system 200 in the low-voltage chamber 1 and the high-voltage busbar system 300 in the high-voltage chamber 2 can be improved. It should be noted that in this embodiment, the door body 120 is pivotally connected to the main body 110, and a handle 121 is provided on the door body 120 to facilitate driving the door body 120 to rotate relative to the main body 110.

[0059] To improve the stability of the main body 110, a connecting ring 114 is provided on the main body 110. The connecting ring 114 can be fixedly connected to the cabin through a rope to prevent the problem that the main body 110 topples due to the bumps generated during the ship's voyage. It should be noted that in this embodiment, 4 connecting rings 114 are circumferentially and spacedly arranged at the upper end of the main body 110 around the circumference of the main body 110, and each connecting ring 114 is hung and fixed to the cabin through a rope. In other embodiments, the number of connecting rings 114 can also be adjusted according to actual needs, and no specific limitation is made in this embodiment.

[0060] Combined with Figure 4 The specific structure of the insulation isolation structure 400 will be described. The insulation isolation structure 400 includes a first bending portion 410 and a second bending portion 420 that are connected to each other. Among them, the extending direction of the first bending portion 410 is perpendicular to the plane where the opening is located, and the extending direction of the second bending portion 420 is parallel to the plane where the opening is located. The second bending portion 420 is arranged at one end of the receiving cavity 111 close to the opening. The first bending portion 410 and a part of the cavity wall of the receiving cavity 111 enclose a low-voltage chamber 1, and the low-voltage chamber 1 is in direct communication with the opening. The second bending portion 420, the first bending portion 410, and a part of the cavity wall of the receiving cavity 111 enclose a high-voltage chamber 2, and the high-voltage chamber 2 is not in direct communication with the opening.

[0061] By setting the insulating isolation structure 400 as the interconnected first bending portion 410 and second bending portion 420, with the extending direction of the first bending portion 410 perpendicular to the plane where the opening is located, the accommodating cavity 111 can be divided into two regions that are directly connected and aligned with the opening. By making the extending direction of the second bending portion 420 parallel to the plane where the opening is located and arranging the second bending portion 420 at one end close to the opening, the second bending portion 420 can block the opening of one of the two regions separated by the first bending portion 410. The region with the blocked opening is used as the high-pressure chamber 2, which can further improve the protection of the battery clusters in the high-voltage busbar system 300. The region without the blocked opening is used as the low-pressure chamber 1, which can further facilitate the subsequent debugging by the staff. When it is necessary to debug the low-voltage control system 200, since the low-pressure chamber 1 is directly connected and aligned with the opening, only the door body 120 needs to be opened to debug the low-voltage control system 200.

[0062] It should be noted that in this embodiment, both the first bending portion 410 and the second bending portion 420 are made of acrylic material. Acrylic material not only has good electrical insulation performance, high surface hardness, surface gloss and good high-temperature performance, but also has good processing performance. It can be either thermoformed or machined. In other embodiments, the first bending portion 410 and the second bending portion 420 can also be made of other insulating materials, and this embodiment does not make specific limitations.

[0063] In addition, in this embodiment, the opening is located on the side of the accommodating cavity 111. The accommodating cavity 111 is split into a low-pressure chamber 1 and a high-pressure chamber 2 that are stacked vertically by the insulating isolation structure 400. The high-pressure chamber 2 is located below the low-pressure chamber 1 to facilitate the high-pressure chamber 2 to accommodate the battery clusters in the high-voltage busbar system 300. In other embodiments, the low-pressure chamber 1 and the high-pressure chamber 2 can also be arranged side by side along the horizontal plane, and this embodiment does not make specific limitations.

[0064] In an alternative embodiment, an intake assembly 112 and an exhaust assembly 113 are provided on the main body 110. The intake assembly 112 is capable of driving external gas into the accommodation chamber 111, and the exhaust assembly 113 is capable of driving the gas in the accommodation chamber 111 to be discharged to the outside. By providing the intake assembly 112 and the exhaust assembly 113 on the main body 110, the circulating flow of the external gas and the gas in the cabinet 100 can be realized, the heat dissipation effect on the low-voltage control system 200 and the high-voltage busbar system 300 in the cabinet 100 can be improved, and further the protection of the low-voltage control system 200 and the high-voltage busbar system 300 can be enhanced. It should be noted that in other embodiments, the intake assembly 112 is provided at the lower end of the main body 110, and the exhaust assembly 113 is provided at the upper end of the main body 110 to further improve the circulating effect of the air in the main body 110. In other embodiments, only the intake assembly 112 may be provided on the main body 110, or only the exhaust assembly 113 may be provided on the main body 110, and no specific limitation is made in this embodiment.

[0065] Specifically, the intake assembly 112 includes a filter window and a fan. Among them, an air inlet is formed on the main body 110, the filter window seals the air inlet, the fan is arranged at one end of the filter window close to the accommodation chamber 111, and the fan is used to drive the external gas to enter the accommodation chamber 111 along the filter window. By forming the air inlet on the main body 110, using the filter window to seal the air inlet, arranging the fan at one end of the filter slot close to the accommodation chamber 111, and driving the external gas to enter the accommodation chamber 111 along the filter slot by the fan, not only can the effective driving of the external gas be realized, but also the gas entering the accommodation chamber 111 can be filtered, preventing sundries from entering the accommodation chamber 111 along the air inlet, and enhancing the protection of the low-voltage control system 200 and the high-voltage busbar system 300. It should be noted that in this embodiment, the filter window is a louver window. In other embodiments, the filter window may also be a tensioning frame with a filter net tensioned, and no specific limitation is made in this embodiment.

[0066] In addition, the specific structure of the exhaust assembly 113 is the same as that of the intake assembly 112. To ensure the conciseness of the text, it will not be elaborated here.

[0067] For the convenience of observing the usage of the marine busbar cabinet, an indicator light 122 is provided on the door body 120, and the indicator light 122 is connected to the harness of the low-voltage control system 200. By providing the indicator light 122 connected to the harness of the low-voltage control system 200 on the door body 120, the staff can observe the indicator light to judge the usage of the marine busbar cabinet, and the indication effect is good. In addition, the indicator light 122 can be switched between the off state, the always-on state, and the flashing state. By using the switching of the indicator light 122 among these three states of the off state, the always-on state, and the flashing state, the indication effect on the staff is further improved. It should be noted that the indicator light 122 includes but is not limited to the running indicator light, the fault indicator light, the alarm indicator light, the SOC (state of charge, remaining power) too low indicator light, the over-high temperature indicator light, the power loss indicator light, the start-stop indicator light, and the reset indicator light. It can be understood that in other embodiments, the specific indication information of the indicator light can be adjusted according to the implementation function requirements, and no specific limitation is made in this embodiment.

[0068] In addition, a touch screen 123 is also provided on the door body 120. The touch screen 123 is connected to the harness of the low-voltage control system 200, and the touch screen 123 can control the low-voltage control system 200. By providing the touch screen 123 on the door body 120 and connecting the touch screen 123 to the harness of the low-voltage control system 200, the touch screen 123 can control the low-voltage control system 200. When it is necessary to adjust the output power of the marine busbar cabinet, it can be achieved by operating the touch screen 123, without opening the door body 120 and adjusting the low-voltage control system 200, which simplifies the adjustment difficulty and improves the adjustment efficiency. It should be noted that the specific structure and working principle of the touch screen 123 both belong to the prior art and will not be elaborated here.

[0069] To further improve the usage safety of the marine busbar cabinet, an emergency stop button 124 is also provided on the door body 120. The emergency stop button 124 is connected to the harness of the high-voltage busbar system 300, and the emergency stop button 124 can independently control the start and stop of the high-voltage busbar system 300. By providing the emergency stop button 124 connected to the harness of the high-voltage busbar system 300 on the door body 120, it is ensured that the emergency stop button 124 can independently control the start and stop of the high-voltage busbar system 300. When an accident occurs to the marine busbar cabinet, the emergency stop button 124 can be directly pressed to stop the operation of the high-voltage busbar system 300, thereby ensuring the usage safety of the marine busbar cabinet.

Among them, the wire harness arrangement structure 130 is arranged in the accommodation cavity 111, and the wire harness arrangement structure 130 is used to store the wire harnesses of the low-voltage control system 200 and the high-voltage busbar system 300. By arranging the wire harness arrangement structure 130 to store the wire harnesses of the low-voltage control system 200 and the high-voltage busbar system 300, the storage effect of the wire harnesses of the low-voltage control system 200 and the high-voltage busbar system 300 can be improved, which can not only improve the tidiness in the accommodation cavity 111, but also facilitate subsequent inspection and maintenance.

[0071] Specifically, as Figure 6 shown, the wire harness arrangement structure 130 includes a first fastening member 131 and a second fastening member 132. Any one of the first fastening member 131 and the second fastening member 132 is provided with a fastening protrusion 1311, and the other is provided with a fastening groove 1321. The fastening protrusion 1311 and the fastening groove 1321 are fastened and fixed, and a wire harness groove 133 is formed between the first fastening member 131 and the second fastening member 132. The wire harness groove 133 is used to store the wire harness.
