Description

Technical Field

[0001] This invention relates to the field of transformer energy storage equipment, and particularly to an integrated energy storage converter and boost converter. Background Technology

[0002] The integrated energy storage converter and boost converter realizes the bidirectional conversion, regulation and boosting of electrical energy, and is one of the most common devices in energy storage systems.

[0003] In the existing design, multiple core functions of the all-in-one unit are integrated into the prefabricated cabin, including an outdoor energy storage converter and a step-up transformer. In addition, it is also equipped with a medium and low voltage power distribution unit and a communication unit.

[0004] In existing designs, the transformer compartment relies on lower side louvers and the bottom of the transformer body for air intake, while exhaust fans are located on the upper sides or the top of the compartment. This cooling method generates turbulence within the transformer compartment, resulting in low cooling efficiency and poor targeted airflow. To meet the transformer temperature rise limit, the number of exhaust fans needs to be increased, increasing costs and installation space. Summary of the Invention

[0005] This invention provides an integrated energy storage converter and boost converter, which is not only convenient for sea transport, but also enables effective heat dissipation in the transformer room.

[0006] The technical solutions to the above problems are as follows: The integrated energy storage converter and booster unit includes a housing, a first partition, a second partition, a third partition, a switch cabinet, a transformer, a circuit breaker cabinet, an energy storage converter, a first conductive component, a second conductive component, a third conductive component, and a first fan. The first, second, and third partitions are located inside the housing, dividing the interior into a first chamber, a second chamber, a third chamber, and a fourth chamber. The switch cabinet is located in the first chamber, the transformer is located in the second chamber, the transformer is connected to the first conductive component, the first conductive component is connected to the switch cabinet, and the circuit breaker cabinet is located in... In the third chamber, the transformer is connected to the second conductive component, the second conductive component is connected to the circuit breaker cabinet, the circuit breaker cabinet is connected to the third conductive component, the energy storage converter is located in the fourth chamber, the third conductive component is connected to the energy storage converter, the enclosure is provided with a first air inlet that cooperates with the second chamber, the first fan cooperates with the second chamber, the top and bottom of the enclosure are provided with corner lock holes for cooperating with corner locks, and also includes a guide plate located in the second chamber that guides the airflow to the transformer, the guide plate is fixed to the enclosure and / or the first partition and / or the second partition.

[0007] In this invention, the lower part of the transformer mates with the second air inlet, and the lower parts of both sides of the housing are louvers for the first air inlet. Under the negative pressure generated by the first fan, airflow enters the second chamber through the first and second air inlets respectively. The second guide plate guides the airflow towards the transformer. After heat exchange with the transformer, the airflow enters the air duct, where it continues to exchange heat with the transformer. Then, after flowing through the gap between the first guide plate and the transformer, it is drawn out of the housing by the first fan. The second guide plate in this invention guides the airflow entering the second chamber, avoiding turbulence within the second chamber and thus improving heat dissipation efficiency.

[0017] like Figures 1 to 7 As shown, the energy storage converter and booster integrated machine of the present invention includes a housing 1, a first partition 2, a second partition 3, a third partition 4, a switch cabinet 5, a transformer 6, a circuit breaker cabinet 7, an energy storage converter 8, a first conductive component, a second conductive component 9, a third conductive component 10, and a first fan 11. The following is a detailed description of each part and the relationship between them.

[0018] The dimensions of container 1 are the same as those of a standard container. Both the top and bottom of container 1 are provided with corner lock holes 1e for engaging with corner locks. Corner locks are a mechanism on port cranes. After the corner lock is inserted into the corner lock hole, the corner lock works to connect the corner lock to container 1, thereby enabling the port crane to lift and move container 1. The structure of the corner lock is existing technology and will not be described here.

[0019] The first partition 2, the second partition 3, and the third partition 4 are located inside the enclosure 1, dividing the interior of the enclosure 1 into a first chamber 1a, a second chamber 1b, a third chamber 1c, and a fourth chamber 1d. The first chamber 1a is a medium-voltage chamber, the second chamber 1b is a transformer chamber, the third chamber 1c is a low-voltage chamber, and the fourth chamber 1d is an energy storage converter.

[0020] The switch cabinet 5 is located in the first chamber 1a. There are two switch cabinets 5, and they are inflatable switch cabinets. The first chamber 1a is also provided with a fifth partition 5a, which divides the first chamber 1a into two small compartments. Each small compartment is equipped with one inflatable switch cabinet. The inflatable switch cabinets are small in size and are arranged reasonably and compactly in the housing 1.

[0021] Transformer 6 is located in the second chamber 1b. The transformer is a dry-type transformer and is connected to the first conductive component, which in turn is connected to the switchgear 5. The first conductive component preferably uses copper busbars. In this invention, the switchgear 5, transformer 6, circuit breaker cabinet 7, and energy storage converter 8 are modularly assembled in a container of the same size as a standard shipping container, which facilitates sea transport and saves on transportation costs.

[0022] Circuit breaker cabinet 7 is located in the third chamber 1c. Transformer 6 is connected to the second conductive component 9, which in turn is connected to circuit breaker cabinet 7. The placement of circuit breaker cabinet 7 between transformer 6 and energy storage converter 8 facilitates subsequent equipment maintenance. Communication cabinet 7a and auxiliary distribution transformer 7b are also installed in the third chamber 1c. Communication cabinet 7a and auxiliary distribution transformer 7b are connected to circuit breaker cabinet 7 via conductive components, which can be copper busbars or cables. The electrical energy output from transformer 6 is transferred to communication cabinet 7a and auxiliary distribution transformer 7b through circuit breaker cabinet 7.

[0023] The circuit breaker cabinet 7 is connected to the third conductive component 10. The energy storage converter 8 is located in the fourth chamber 1d. The third conductive component 10 is connected to the energy storage converter 8. The third conductive component 10 preferably uses copper busbars.

[0024] The housing 1 is provided with a first air inlet 12 that cooperates with the second chamber 1b. The first air inlet 12 contains filter cotton and is a louver. A first fan 11 cooperates with the second chamber 1b. The housing also includes a guide plate located within the second chamber 1b that directs airflow towards the transformer 6. The guide plate is fixed to the housing 1 and / or the first partition 2 and / or the second partition 3. In this embodiment, the guide plate includes a first guide plate 25 and a second guide plate 26, arranged one above the other. There are two of each guide plate, distributed on both sides of the transformer 6. Both the first guide plate 25 and the second guide plate 26 are fixed to the housing 1, forming an air duct 6a between the first guide plate 25, the second guide plate 26, the housing 1, and the transformer 6. The bottom of the housing 1 is provided with a second air inlet that cooperates with the second chamber 1b, and a first mesh 1f is installed at this second air inlet.

[0025] The lower part of the transformer 6 mates with the second air inlet, and the lower parts of both sides of the housing 1 are louvered first air inlets 12. Under the negative pressure generated by the first fan 11, airflow enters the second chamber 1b through the first air inlet 12 and the second air inlet, respectively. The second guide plate 26 guides the airflow toward the transformer 6. After heat exchange with the transformer 6, the airflow enters the air duct 6a, where it continues to exchange heat with the transformer. Then, after flowing through the gap between the first guide plate 25 and the transformer 6, it is drawn out of the housing 1 by the first fan 11. The second guide plate 26 in this invention guides the airflow entering the second chamber 1b, avoiding turbulence in the second chamber 1b, thereby improving heat dissipation efficiency.

[0026] The housing 1 is equipped with a first air inlet louver 13 and a first air outlet louver 14, which are respectively matched with the first chamber 1a. The first air inlet louver 13 is equipped with filter cotton. Airflow enters the first chamber 1a through the first air inlet louver 13, exchanges heat with the switch cabinet 5, and then exits through the first air outlet louver 14, thereby facilitating heat dissipation of the switch cabinet 5.

[0027] The housing 1 is equipped with a second air inlet louver 15, which contains filter cotton. The third partition 4 is equipped with a second air outlet louver 16. The second air inlet louver 15 is fitted with the third chamber 1c, and the second air outlet louver 16 is fitted with both the third chamber 1c and the fourth chamber 1d. Airflow enters the third chamber 1c through the second air inlet louver 15, exchanges heat with the circuit breaker cabinet 7, communication cabinet 7a, and auxiliary distribution transformer 7b, and then exits through the first air outlet louver 14, thereby facilitating heat dissipation for the circuit breaker cabinet 7, communication cabinet 7a, and auxiliary distribution transformer 7b.

[0028] The fourth chamber 1d is equipped with a protective sleeve 17 and a wire clamp 18. A through hole is provided on the third partition 4. One end of the protective sleeve 17 engages with the through hole on the third partition 4. A portion of the third conductive component 10 passes through the through hole into the protective sleeve 17 and is fixed to the wire clamp 18. The wire clamp 18 is fixed to the protective sleeve 17. A clearance opening 17a is provided on the side wall of the protective sleeve 17. The other portion of the third conductive component 10 passes through the clearance opening and connects to the energy storage converter 8. Since there are multiple energy storage converters 8 in the fourth chamber 1d, the length of the third conductive component 10 needs to be relatively long. Therefore, the wire clamp 18 provides support for the third conductive component 10, and the protective sleeve 17 protects the third conductive component 10.

[0029] The energy storage converter and booster integrated unit of the present invention also includes a second fan 19, which is installed at the other end of the protective sleeve 17. The bottom of the protective sleeve 17 is provided with a second air inlet 17b, and the bottom of the housing 1 is provided with a second mesh for air intake. The second mesh cooperates with the fourth chamber 1d, and the positions of the second mesh and the second air inlet 17b correspond. The internal space of the protective sleeve 17 forms an air passage. When the second fan 19 is working, the airflow enters the air duct inside the protective sleeve 17 from the second mesh and the second air inlet 17b at the bottom of the housing 1, and exchanges heat with the third conductive component 10 inside the protective sleeve 17, thereby dissipating heat from the third conductive component 10.

[0030] The energy storage converter and booster integrated unit of the present invention also includes a fan cover 20, a support plate 21, a cover plate 22, a connecting rod 23, and a cotton mesh frame 24. The fan cover 20 is matched with the first fan 11 and fixed to the housing 1. The fan cover 20 has an outlet for supplying airflow. The support plate 21 is fixed to the housing 1. One end of the cover plate 22 is hinged to the support plate 21, and the other end of the cover plate 22 is hinged to one end of the connecting rod 23. The other end of the connecting rod 23 is hinged to the fan cover 20. The cotton mesh frame 24 is installed inside the fan cover 20 and is used to filter impurities in the airflow.

[0031] Since the airflow entering the second chamber 1b from the second air inlet at the bottom of the housing 1 and the first air inlet louver 13 is at room temperature, its temperature will rise after heat exchange with the transformer 6. Therefore, the airflow discharged from the first fan 11 is hot air. Through the structure formed by the fan cover 20, support plate 21, cover plate 22, and connecting rod 23, when the cover plate 22 is opened, an opening is formed between the cover plate 22 and the fan cover 20 to guide the airflow discharged by the first fan 11 upwards towards the housing 1. At this time, if the first fan 11 discharges hot air, it will guide the hot air upwards towards the housing 1, preventing the hot air from flowing downwards and entering the second chamber 1b through the second air inlet, thereby ensuring the heat dissipation of the transformer 6. The airflow direction is shown in the figure. Figure 8 The thick arrow in the middle.

[0032] When the first fan 11 is not needed for exhaust during equipment maintenance or transportation, a force is applied to the cover plate 22, causing the cover plate 22 to rotate and engage with the fan cover 20, thereby closing the outlet of the fan cover 20.

[0033] In summary, this invention modularly assembles the switchgear 5, transformer 6, circuit breaker cabinet 7, and energy storage converter 8 into a container of the same size as a standard shipping container, which is beneficial for sea transport and saves transportation costs. A circuit breaker 7 is installed between the transformer 6 and the energy storage converter 8 for easy maintenance. Various air intake and exhaust structures are incorporated to effectively dissipate heat from each chamber and improve the overall heat dissipation efficiency of the integrated unit.
