[0029] This application provides a power distribution cabinet that is used for high-power electrical equipment. For example, it can be used in energy storage containers, ship electric propulsion systems, electric vehicle charging stations, etc. For ease of description, the following uses the power distribution cabinet applied to an energy storage container as an example:

[0030] When the power distribution cabinet is applied to the energy storage container, it is located inside the energy storage container and is electrically connected to the power integration device to transmit the power in the power integration device to external locations.

[0031] The power distribution cabinet comprises a cabinet body and a cabinet door. The cabinet body is placed on a work floor, and one side of the cabinet body is open to form a storage space. The cabinet door is openably covered on the cabinet body to open or close the storage space.

[0032] See Figure 1For the sake of ease of description and understanding, the state of the distribution cabinet when in use is used as a reference, the up and down directions of the cabinet body are referred to as the up and down directions below; the opening direction of the cabinet body's accommodating space is referred to as the front below, and the direction away from the front is referred to as the rear below; the direction perpendicular to the up and down directions and the front and back directions is referred to as the left and right directions below.

[0033] See Figures 1 to 3 The present application provides a power distribution cabinet, which may include a cabinet body 100, a switch assembly and a cabinet door assembly 200. The cabinet body 100 has an accommodating space 110 inside. The front side of the cabinet body 100 is open to communicate with the accommodating space. The switch assembly includes at least two switch elements, and the switch element has a main body and a switch operating part, and the main body is installed in the accommodating space 110. The cabinet door assembly 200 may include a top cabinet door 210, at least one middle cabinet door 220, and a bottom cabinet door 230 arranged in sequence from top to bottom. The top cabinet door 210, the middle cabinet door 220 and the bottom cabinet door 230 are respectively rotatably covered on the cabinet body 100 for opening and closing the accommodating space 110. The bottom cabinet door 230 and at least one middle cabinet door 220 are both provided with switch holes, and each switch hole is arranged opposite to each switch element. When the cabinet door assembly 200 is covered on the cabinet body 100, the switch operating part of the switch element passes through the switch hole and protrudes from the cabinet door assembly 200.

[0034] The cabinet 100 houses a switch assembly. The top, middle, and bottom doors 210, 220, and 230 are rotatably mounted on the cabinet 100 to open and close the storage space 110. The switch holes in the middle and bottom doors 220 and 230 accommodate the switch operating portions of the two switch components, respectively.

[0035] When the middle and bottom doors 220 and 230 are closed over the cabinet body 100, they shield and physically isolate the main bodies of the switch components, ensuring the safety of workers and preventing electric shock. Furthermore, workers can manipulate the switch operating units within the switch assembly through the switch holes to control the operating status of the main bodies of the switch components, improving the operating efficiency of the power distribution cabinet.

[0036] Furthermore, when a switch assembly fails, workers can open the middle cabinet door 220 and the bottom cabinet door 230 separately to inspect and maintain the faulty portion of the switch assembly, improving operational convenience. This also prevents workers from being affected by other parts of the switch assembly, reducing the risk of electric shock and improving worker safety. This effectively resolves the conflict between convenience and safety in power distribution cabinets.

[0037] In this embodiment, the cabinet 100 includes a top wall and a bottom wall spaced apart in parallel, and a left side wall, a right side wall, and a rear side wall connecting the top and bottom walls. The top, bottom, left side wall, right side wall, and rear side wall together form a cabinet 100 with an accommodating space 110. Accommodating space 110 is used to accommodate a switch assembly, thereby enabling the cabinet 100 to protect the switch assembly.

[0038] In some embodiments, a plurality of heat dissipation holes 121 are provided on the rear side wall of the cabinet body 100 for dissipating heat from electrical components in the accommodating space 110 , thereby extending the service life of the power distribution cabinet.

[0039] In other embodiments, a plurality of heat dissipation holes 121 are formed on the left and right walls of the cabinet 100 .

[0040] In this embodiment, auxiliary reinforcement members 130 may be provided on the left side wall, the right side wall and / or the rear side wall of the cabinet 100 to ensure the structural strength, safety and reliability of the cabinet 100 .

[0041] In some embodiments, the auxiliary reinforcement 130 may be a reinforcement rib, a reinforcement beam, or the like.

[0042] In some embodiments, the cabinet 100 may be provided with a plurality of partitions (not shown) within the accommodating space 110. The partitions extend horizontally to abut against the inner walls of the accommodating space 110. The plurality of partitions are arranged at intervals in the vertical direction to partition the accommodating space 110, thereby enabling the accommodating space 110 to accommodate a variety of electrical components and improving the space utilization of the accommodating space 110.

[0043] In other embodiments, the partition plate is detachably connected to the cabinet body 100 so as to divide the accommodating space 110 according to actual application requirements.

[0044] In other embodiments, the left and right sides of the partition plate are detachably connected to the auxiliary reinforcement member 130 to facilitate supporting electrical components in the power distribution cabinet.

[0045] In this embodiment, the power distribution cabinet may further include a lifting lug 140. The lifting lug 140 is provided on the top of the cabinet body 100 to facilitate transportation and movement of the power distribution cabinet.

[0046] In this embodiment, the power distribution cabinet may include a switch assembly (not shown). The switch assembly is housed in the housing 110 of the cabinet 100. The switch assembly can be electrically connected to the power integration device and an external location to control the connection between the power integration device and the external location.

[0047] In some embodiments, the switch assembly may include at least two switch elements. The switch element has a main body and a switch operating part. The main body is installed in the accommodating space 110 to physically isolate the main body to prevent workers from electric shock and endanger their lives.

[0048] In some embodiments, a switch element in the switch assembly can be a rotary knife switch. The rotary knife switch is connected to a partition plate and disposed near the center of the accommodating space 110. The rotary knife switch is positioned relative to the switch hole in the middle cabinet door 220 so that the switch operating portion of the rotary knife switch can be accommodated in the switch hole in the middle cabinet door 220.

[0049] It should be understood that the rotary knife switch requires a power wrench (not shown) to assist in closing and opening the switch. When the operator needs to switch the operating state of the rotary knife switch, the power wrench is inserted into the rotary knife switch through the switch hole on the middle cabinet door 220 and rotated to close or open the rotary knife switch.

[0050] Therefore, the rotary knife switch is located in the middle of the accommodating space 110 to accommodate the position of the human hand, making it easier for the human hand to apply force to rotate the power wrench. The position of the rotary knife switch conforms to the ergonomic position of the hand and facilitates the application of force by the hand, making it easier for the operator to apply force to switch the operating state of the rotary knife switch, effectively improving the operating efficiency of the rotary knife switch.

[0051] In some embodiments, the rotary knife switch is connected to the partition plate to ensure the stability and reliability of the rotary knife switch.

[0052] In other embodiments, the rotary knife switch may be disposed in the upper portion of the accommodating space 110, with the switch operating portion of the rotary knife switch located near the middle portion of the accommodating space 110. The switch operating portion of the rotary knife switch is disposed relative to the switch hole of the middle cabinet door 220, so that a worker can apply force to the power wrench through the switch hole of the middle cabinet door 220, thereby facilitating control of the rotary knife switch and improving operational efficiency.

[0053] In some embodiments, the rotary knife switch may be a 2500A rotary knife switch.

[0054] In this embodiment, another switching element in the switch assembly may be a circuit breaker. The circuit breaker has functions such as phase loss, overload, and overcurrent protection. Therefore, the closing and opening operations of the circuit breaker require a high frequency of operation.

[0055] The switch operating part of the circuit breaker includes a closing button and an opening button. The staff can control the closing and opening operations of the circuit breaker by only operating the closing button and the opening button. The operating requirements and force required for the staff are relatively low.

[0056] The circuit breaker is located below and spaced apart from the rotary knife switch. It is attached to a partition plate to confine it to the lower portion of the accommodating space 110. The circuit breaker's switch operating unit is positioned relative to the switch hole in the bottom cabinet door 230, allowing operators to quickly operate the circuit breaker by pressing the closing and opening buttons, improving circuit breaker operation efficiency.

[0057] In some embodiments, the switch operating part of the circuit breaker can extend forward beyond the bottom cabinet door 230 to facilitate the staff to press the closing button and the opening button, thereby improving the control convenience of the circuit breaker and improving the operating efficiency of the circuit breaker.

[0058] In other embodiments, the switch operating part of the circuit breaker further includes a variety of other control buttons, all of which can extend forward beyond the bottom cabinet door 230, thereby facilitating operation by workers.

[0059] In some embodiments, there may be multiple circuit breakers. The multiple circuit breakers can be arranged in intervals along the left-right direction. That is, the switch assembly may include a rotary knife switch and multiple circuit breakers.

[0060] In other embodiments, there may be two circuit breakers, which are spaced apart along the left-right direction within the accommodating space 110. That is, the switch assembly may include a rotary knife switch and two circuit breakers.

[0061] In some embodiments, the circuit breaker is connected to a partition plate to ensure the stability and reliability of the circuit breaker.

[0062] In some embodiments, the circuit breaker may be a molded case circuit breaker. In other embodiments, the circuit breaker may be a 1250A frame-type molded case circuit breaker.

[0063] In this embodiment, the cabinet door assembly 200 includes a top cabinet door 210, at least one middle cabinet door 220, and a bottom cabinet door 230. The top cabinet door 210, the middle cabinet door 220, and the bottom cabinet door 230 are all rotatably connected to the cabinet body 100 for opening and closing the accommodating space 110.

[0064] In this embodiment, an indicator hole 211 may be opened on the top cabinet door 210 .

[0065] The power distribution cabinet may further include an indicator light assembly (not shown). The indicator light assembly is arranged on the inner side of the top cabinet door 210, and part of the indicator light assembly is accommodated in the indicator hole 211 and emits light to display the use status of the power distribution cabinet.

[0066] The indicator light assembly may include at least one indicator light having a connection terminal and a light emitting portion, wherein the connection terminal is located inside the indicator hole, and the light emitting portion passes through the indicator hole 211 and extends to the outside of the top cabinet door 210 to emit light.

[0067] The top door 210 is separated from the middle door 220. When the middle door 220 needs to be opened and closed to inspect or repair the rotary knife switch, the top door 210 does not need to be opened and closed frequently, thereby effectively extending the service life of the top door 210 and improving the convenience of operation for the staff.

[0068] In some embodiments, a plurality of indicator holes 211 are formed on the top cabinet door 210 . The plurality of indicator holes 211 are spaced apart along the left-right direction to respectively accommodate portions of the indicator light assembly.

[0069] In some other embodiments, three indicator holes 211 are formed on the top cabinet door 210 , and the three indicator holes 211 are spaced apart in the left-right direction.

[0070] The indicator light assembly may include a first indicator light, a second indicator light, and a third indicator light. The first indicator light, the second indicator light, and the third indicator light are respectively accommodated in the three indicator holes 211, so that the multiple light-emitting parts can emit lights of different colors respectively, thereby being used to display the operating status of the distribution cabinet.

[0071] In some embodiments, the indicator light is a three-phase power supply indicator light.

[0072] In some embodiments, a top reinforcing rib 212 may be provided on the top cabinet door 210. The top reinforcing rib 212 extends in the left-right direction to strengthen the structural strength of the top cabinet door 210, thereby extending the service life of the power distribution cabinet.

[0073] In some embodiments, the top reinforcing rib 212 is located near the middle of the top cabinet door and near the indicator hole 211 in the up and down directions, so that the top reinforcing rib 212 can ensure the structural strength and reliability of the top cabinet door 210 around the indicator hole 211 .

[0074] In other embodiments, the top reinforcing rib 212 is located below the indicator hole 211 so that the top reinforcing rib 212 can also bear the gravity load of the indicator light assembly, thereby improving the structural strength and stability of the top cabinet door 210 .

[0075] In other embodiments, top reinforcing ribs 212 are disposed on the upper and lower sides of the indicator hole 211 to strengthen the structural strength of the top cabinet door 210 , thereby ensuring the structural strength and stability of the top cabinet door 210 .

[0076] In other embodiments, the top reinforcing ribs 212 are arranged around the circumference of the multiple indicator holes 211 so that the multiple indicator holes 211 are located within the enclosed range of the top reinforcing ribs 212, thereby strengthening the structural strength and stability of the top cabinet door 210 around the indicator holes 211.

[0077] In this embodiment, the cabinet door assembly 200 may include a middle cabinet door 220 . That is, the cabinet door assembly 200 may include three cabinet doors, namely a top cabinet door 210 , a middle cabinet door 220 , and a bottom cabinet door 230 .

[0078] The middle cabinet door 220 has a switch hole corresponding to the rotary knife switch, referred to as the middle switch hole 221. This hole is located at the top of the middle cabinet door 220, corresponding to the switch operating unit of the rotary knife switch. Specifically, the hole 221 is positioned near the center of the cabinet body 100. When a worker holds a power-assisted wrench, the hole's location facilitates quick insertion of the wrench into the switch operating unit. It also facilitates the worker's hand's application of force to rotate the rotary knife switch, ergonomically accommodating the user.

[0079] Moreover, when the rotary knife switch needs maintenance or inspection, the staff can open the middle cabinet door 220 to inspect or maintain the rotary knife switch, thereby avoiding other electrical components in the distribution cabinet from affecting the staff, facilitating the inspection and maintenance of the rotary knife switch, and ensuring the safety of the staff.

[0080] When the cabinet door assembly 200 includes a top cabinet door 210, a middle cabinet door 220, and a bottom cabinet door 230, the height of the cabinet body 100 in the vertical direction is 1785mm to 1815mm, the height of the top cabinet door 210 is 237mm to 247mm, the height of the middle cabinet door 220 is 387mm to 397mm, and the height of the bottom cabinet door 230 is 1037mm to 1047mm. The height dimensions of the cabinet body 100, the top cabinet door 210, the middle cabinet door 220, and the bottom cabinet door 230 ensure a reasonable height layout of the cabinet doors.

[0081] When the rotary knife switch is closed, a large force is required to rotate it. The rotary knife switch is installed on the middle cabinet door 220 and is close to the middle of the cabinet body 100. The middle switch hole 221 on the middle cabinet door 220 is set relative to the switch operating part of the rotary knife switch. The height position of the middle switch hole 221 is most ergonomic and saves the most effort.

[0082] In some embodiments, the cabinet door assembly 200 includes a plurality of middle cabinet doors 220 , wherein a middle cabinet door 220 is provided with a middle switch hole 221 corresponding to the rotary knife switch to facilitate the operation, inspection and maintenance of the rotary knife switch.

[0083] When the middle cabinet door 220 is closed on the cabinet body 100, the middle switch hole 221 is used to accommodate the switch operating part of the rotary knife switch, so that the power wrench can be inserted into the rotary knife switch through the middle switch hole 221 on the middle cabinet door 220, thereby facilitating the staff to close and open the rotary knife switch through the power wrench.

[0084] When the rotary knife switch needs maintenance or inspection, the staff can open the corresponding middle cabinet door 220 to inspect or maintain the rotary knife switch, thereby preventing other electrical components in the distribution cabinet from affecting the staff and ensuring the safety of the staff.

[0085] For example, when a worker opens the middle cabinet door 220 to inspect and maintain the rotary knife switch, the worker can be prevented from being affected by the circuit breaker, thereby ensuring the worker's life safety.

[0086] In some embodiments, in a plane perpendicular to the front-to-back direction, the switch operating part of the rotary knife switch is located within the enclosed range of the middle switch hole 221 on the middle cabinet door 220, thereby facilitating the power wrench to pass through the middle switch hole 221 to be inserted into the switch operating part of the rotary knife switch, thereby improving the operating efficiency of the staff.

[0087] In other embodiments, in the front-to-back direction, the switch operating portion of the rotary knife switch can partially extend forward beyond the middle cabinet door 220, thereby facilitating the staff to insert the power wrench into the switch operating portion of the rotary knife switch, thereby improving the staff's operating efficiency.

[0088] In other embodiments, the switch assembly may further include other switch devices, which may be located on the upper and / or lower side of the rotary knife switch. The rotary knife switch and other switch devices may be respectively arranged corresponding to a middle cabinet door 220, and a middle switch hole 221 is provided on each of the middle cabinet doors 220, so that the switch operating part of the rotary knife switch and the switch operating part of the other switch devices can be respectively accommodated in the middle switch holes 221 on the two middle cabinet doors 220, thereby facilitating the staff to operate the rotary knife switch and other switch devices, so as to be able to control the closing and opening of the rotary knife switch and other switch devices respectively.

[0089] In this embodiment, the cabinet door assembly 200 includes a bottom cabinet door 230. Bottom cabinet door 230 is positioned relative to the circuit breaker. A switch hole is provided in bottom cabinet door 230, relative to the circuit breaker's switch operating unit, for accommodating the circuit breaker's switch operating unit. This facilitates operator control of the circuit breaker's closing and opening via the switch operating unit. This switch hole in bottom cabinet door 230 is referred to as bottom switch hole 231.

[0090] Moreover, when the circuit breaker fails, the staff can inspect and repair the circuit breaker by opening the bottom cabinet door 230, thereby improving the convenience of using the distribution cabinet and avoiding other switching elements such as rotary knife switches affecting the staff when inspecting and repairing the circuit breaker, reducing the risk of electric shock to the staff and effectively protecting the life, health and safety of the staff.

[0091] In some embodiments, in a plane perpendicular to the front-to-back direction, the switch operating part of the circuit breaker is located within the enclosed range of the bottom switch hole 231, thereby facilitating the staff to press the closing button and the opening button through the bottom switch hole 231 on the bottom cabinet door 230, thereby improving the staff's operating efficiency.

[0092] In other embodiments, in the front-to-back direction, the switch operating portion of the circuit breaker can partially extend forward to exceed the bottom cabinet door 230 , thereby facilitating the operator to press the switch operating portion of the circuit breaker and improving the operator's operating efficiency.

[0093] In this embodiment, the bottom cabinet door 230 may have multiple bottom switch holes 231, with the multiple bottom switch holes 231 spaced apart. The multiple bottom switch holes 231 on the bottom cabinet door 230 may be positioned relative to multiple circuit breakers to accommodate the switch operating components of the multiple circuit breakers, thereby facilitating user operation of the multiple circuit breakers and improving circuit breaker operation efficiency.

[0094] In this embodiment, the bottom cabinet door 230 may include a bottom door body and a cover body that can be separated from the bottom door body. After the cover body is separated from the bottom door body, a bottom switch hole 231 is formed on the bottom door body.

[0095] In some embodiments, there may be one circuit breaker.

[0096] When there is only one circuit breaker, a cover is separated from the bottom door to form a bottom switch hole 231. A bottom switch hole 231 is arranged opposite to a circuit breaker so that the switch operating part of the circuit breaker can extend forward through the bottom switch hole 231 to the bottom cabinet door 230, making it easier for operators to operate the circuit breaker.

[0097] In some embodiments, there may be two circuit breakers.

[0098] When there are two circuit breakers, the bottom door separates the two covers to form two bottom switch holes 231 on the bottom door. The two bottom switch holes 231 are respectively arranged opposite the two circuit breakers so that the switch operating parts of the two circuit breakers can extend forward to the bottom cabinet door 230 through the two bottom switch holes 231, thereby facilitating the operation of the two circuit breakers.

[0099] In some embodiments, there may be multiple circuit breakers.

[0100] When there are multiple circuit breakers, the bottom door is separated into multiple covers to form multiple bottom switch holes 231 on the bottom door. The multiple bottom switch holes 231 are respectively arranged opposite the multiple circuit breakers, so that the switch operating parts of the multiple circuit breakers can extend forward to the bottom cabinet door 230 through the multiple bottom switch holes 231, thereby facilitating the operation of multiple circuit breakers by the operator.

[0101] In this embodiment, the cover and the bottom door are integrally formed. When assembling the distribution cabinet, the cover can be separated according to the number and installation location of the circuit breakers, thereby enabling the number of bottom switch holes 231 to be adjusted in real time according to the number of circuit breakers, thereby increasing the applicability of the distribution cabinet.

[0102] Furthermore, the integral formation of the cover and the bottom door ensures the integrity of the bottom door 230, effectively improving the structural strength and load-bearing capacity of the bottom door 230 and extending the service life of the bottom door 230. Furthermore, when the cover is attached to the bottom door, the front side of the cover is flush with the front side of the bottom door, resulting in a smooth and aesthetically pleasing surface for the bottom door 230.

[0103] In some embodiments, the cover is detachably connected to the bottom door. When the cover is detachably connected to the bottom door, the cover is positioned over the bottom door and located in front of the bottom door. When the power distribution cabinet is assembled, the cover can be removed to allow the circuit breaker to extend forward from the bottom door.

[0104] When the power distribution cabinet needs to be modified, the staff can connect the cover to the bottom door body to cover the bottom switch hole 231, so as to facilitate the reuse of the power distribution cabinet.

[0105] In this embodiment, the bottom door 230 may be provided with a bottom reinforcing rib 232. The bottom reinforcing rib 232 extends in the left-right direction. In the vertical direction, the bottom reinforcing rib 232 is located near the center of the bottom door 230 and near the bottom switch hole 231 of the bottom door 230. This strengthens the structural strength of the bottom reinforcing rib 232 around the bottom switch hole 231, prevents the bottom door 230 from tilting due to frequent opening and closing, and ensures the reliability and stability of the bottom door 230.

[0106] In some embodiments, the bottom reinforcing rib 232 is disposed below the bottom switch hole 231 to ensure the structural strength and stability of the bottom cabinet door 230 .

[0107] In some embodiments, locking structures are provided on the top cabinet door 210, the middle cabinet door 220, and the bottom cabinet door 230. The top cabinet door 210, the middle cabinet door 220, and the bottom cabinet door 230 are respectively locked to the cabinet body 100 through locking assemblies.

[0108] When the top cabinet door 210, the middle cabinet door 220 and the bottom cabinet door 230 are covered on the cabinet body 100, the staff can use the locking structure to limit the top cabinet door 210, the middle cabinet door 220 and the bottom cabinet door 230 on the cabinet body 100 to ensure the safety of the distribution cabinet and prevent the staff from being electrocuted.

[0109] Furthermore, the staff can also open the top cabinet door 210, the middle cabinet door 220 and the bottom cabinet door 230 respectively through the locking structure to facilitate the staff's inspection and maintenance.

[0110] In this embodiment, the power distribution cabinet may further include an instrument assembly (not shown). The instrument assembly is disposed on the bottom plate of the cabinet body 100, below the circuit breaker, and opposite the bottom cabinet door 230. A staff member can open the bottom cabinet door 230 to inspect the instrument assembly.

[0111] In some embodiments, the meter assembly may include multiple miniature circuit breakers and electric meters, so that a worker can operate the miniature circuit breakers in the meter assembly separately and check the electric meter data by opening the bottom cabinet door 230 .

[0112] See Figures 1 to 3 The present application provides a power distribution cabinet, wherein a rotary knife switch and a circuit breaker are housed within a cabinet body 100. A top cabinet door 210, a middle cabinet door 220, and a bottom cabinet door 230 are rotatably mounted on the cabinet body 100 to respectively open and close a storage space 110. A central switch hole 221 in the middle cabinet door 220 can accommodate the switch operating unit of the rotary knife switch. A bottom panel switch hole in the bottom cabinet door 230 can accommodate the switch operating unit of the circuit breaker.

[0113] When the middle and bottom doors 220 and 230 are closed on the cabinet body 100, they can shield the main body of the switch components, ensuring the safety of workers and preventing electric shock. At the same time, workers can also control the rotary knife switch and circuit breaker through the switch holes to control the operating status of the power distribution cabinet.

[0114] Moreover, when a switch assembly fails, the staff can also open the middle cabinet door 220 and the bottom cabinet door 230 separately, so that the staff can inspect and maintain the rotary knife switch and / or circuit breaker separately, thereby improving the staff's operating convenience and preventing the staff from being affected by other parts of the switch assembly, reducing the risk of electric shock, and improving the safety of the staff.

[0115] The present application also provides a supercharge energy storage container, which includes: a box body (not shown in the figure), a supercharge host (not shown in the figure), an energy storage module (not shown in the figure), and the above-mentioned power distribution cabinet. The supercharge host, energy storage module, and power distribution cabinet are all installed in the box body, and the electrical components in the power distribution cabinet are electrically connected to the supercharge host and the energy storage module respectively.

[0116] In some embodiments, the power distribution cabinet may include a switch assembly. The switch assembly may include a circuit breaker. The circuit breaker may be a 1250A frame-type molded case circuit breaker, and its load is a 600KW supercharger host.

[0117] In some embodiments, the power distribution cabinet can serve as the power input end of the supercharging energy storage container, connecting to the mains power grid and distributing power to the supercharging host and energy storage module.
