Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

At present, in an integrated machine integrating a photovoltaic inverter and a transformer, a plurality of cabinets (single machines) are adopted for parallel operation. As shown in fig. 1, three cabinets 01 are integrated with a transformer 02 into an integrated machine, and the three cabinets 01 work in parallel. It is understood that the cabinet 01 may be an inverter or power cabinet.

The cabinet output bus 011 of each cabinet 01 is connected in parallel to the bus 03, which can be understood as the cabinet output bus 011 is connected to the input end of the bus 03. The bus 03 extends from the inside of one cabinet 01 and sequentially passes through the other cabinets 01, and the output end of the bus 03 is connected to the transformer 02. In order to meet the protection requirement, protection connection pipes 04 are arranged between two adjacent cabinets 01 and between the transformer 01 and the adjacent cabinet 01, and the protection connection pipes 04 are used for allowing bus bars 03 to pass through.

In order to facilitate the disassembly and assembly of the cabinet 01, the bus 03 comprises a plurality of bus segments connected in sequence, and two adjacent bus segments are detachably connected. When some cabinets 01 are out of order and need to be dismantled, the bus segments in the cabinets to be dismantled, namely the parts of the bus bars 03 need to be dismantled, so that the dismantling and replacement of the cabinets 01 are time-consuming and labor-consuming.

As shown in fig. 1 and fig. 2, after the middle cabinet 01 of the three cabinets 01 is removed, the bus 03 is disconnected, and the disconnected bus conductive member 03 needs to be reconnected to ensure that the remaining two cabinets 01 work normally, so that after the partial cabinets 01 are removed, the remaining cabinets 01 are restored to be parallel to each other, and the normal work is also time-consuming and labor-consuming. Moreover, because the supplementary bus-section exposes in outdoor environment, need adopt interim protective structure 05 to protect the bus-section that exposes, the operation degree of difficulty is great, wastes time and energy.

In view of the above-mentioned problem, disclosed in this embodiment of the present application are a cabinet parallel operation structure and an integrated machine with a cabinet parallel operation structure, so as to improve convenience of dismantling and replacing a cabinet, and improve convenience of recovering and operating the remaining cabinets in parallel operation under the condition that a part of the cabinet is dismantled.

As shown in fig. 3, the cabinet parallel operation structure includes: a first cabinet 1, a second cabinet 2, a bus bar 3, a bus bar guard 4 and a communication assembly 5.

At least two first cabinets 1 are arranged, and any two first cabinets 1 are connected to the bus bar 3 in parallel. The first cabinets 1 have cabinet output buses 101, that is, any two cabinet output buses 101 of the first cabinets 1 are connected in parallel to the bus bar 3. It will be appreciated that the cabinet output bus 101 is connected in parallel to the input of the bus bar 3.

The output end of the bus bar 3 is electrically connected to the input end of the second cabinet 2. It will be appreciated that the bus bar 3 electrically connects the cabinet output bus bar 101 of the first cabinet 1 with the input end of the second cabinet 2, and that the bus bar 3 acts as a bus, i.e. the bus bar 3 buses the output of each first cabinet to the second cabinet 2.

The cabinet output bus 101 is just one specific structure of the cabinet output member. The cabinet output member may also be other conductive members, which is not limited in this embodiment.

The bus bar 3 may be a copper bar, the bus bar 3 is only one specific structure of a bus conductive member, and the bus conductive member may be another conductive member.

The second cabinet 2 may be a transformer, which may be a medium voltage transformer. Of course, the second cabinet 2 may also be other electrical devices for summarizing power, converting voltage, converting frequency. The specific type of the second cabinet 2 is not limited in this embodiment.

The busbar protection 4 is used for protecting the busbar 3, wherein the busbar 3 is positioned in the busbar protection 4. It will be appreciated that the busbar guard 4 has an internal cavity for receiving the busbar 3. The busbar protection member 4 may be a protection sleeve, a protection shell, or the like, which is not limited in this embodiment.

In some embodiments, where the bus bar 3 is replaced with a bus conductor having protective properties, the rack parallel operation structure may not include the bus guard 4.

In the above cabinet parallel operation structure, all the first cabinets 1 need to be connected in communication. In some embodiments, two adjacent first cabinets 1 are communicatively connected. In order to facilitate the removal of the first cabinets 1, two adjacent first cabinets 1 are communicatively connected by means of a communication assembly 5, which communication assembly 5 is detachable such that the communication connection of two adjacent first cabinets 1 is detachable.

To solve the above problem, the bus bar 3 and the bus bar guard 4 are both located outside the first cabinet 1, the cabinet output bus bar 101 extends to the outside of the first cabinet 1, and the cabinet output bus bar 101 extends inside the bus bar guard 4. It will be appreciated that the busbar 3 and busbar guard 4 are both located outside the second cabinet 2.

In the cabinet parallel operation structure, when part of the first cabinet 1 fails and needs to be removed, for example, one or some first cabinets 1 fail and need to be removed, the connection between the cabinet output bus 101 and the bus 3 of the first cabinet 1 to be removed is removed outside the first cabinet 1, and the part of the bus 3 does not need to be removed; moreover, the connection of the cabinet output bus 101 and the bus 3 of the first cabinet 1 to be dismantled is dismantled, and the continuity of the bus 3 is not influenced, so that the connection of the rest first cabinets 1 is not influenced, and the convenience of the rest first cabinets 1 in recovery and normal operation is improved under the condition that part of the first cabinets 1 are dismantled; meanwhile, the bus bar 3 is protected by the bus bar protection piece 4, so that the protection performance is guaranteed, a temporary protection structure is not required to be added, the operation difficulty is reduced, and the convenience is improved. Therefore, the cabinet-combined structure can meet the requirement of quick maintenance.

In some embodiments, as shown in fig. 3, the input end of the second cabinet 2 is provided with an input terminal 201, and the output end of the bus bar 3 is connected with the input terminal 201. In order to improve the shielding performance, the input terminal 201 may optionally extend into the busbar protection 4, i.e. the input terminal 201 and the busbar 3 are electrically connected within the busbar protection 4.

As shown in fig. 4, the bus bar shield 4 has bus bar inlets 403 in one-to-one correspondence with the cabinet output bus bars 101, and the bus bar inlets 403 are used for allowing the cabinet output bus bars 101 to extend into the interior of the bus bar shield 4, that is, the cabinet output bus bars 101 extend from the bus bar inlets 403 into the bus bar shield 4. After the connection between the cabinet output bus 101 of the first cabinet 1 to be dismantled and the bus bar 3 is dismantled, the dismantled cabinet output bus 101 needs to be moved out of the bus bar protection piece 4, after the dismantled cabinet output bus 101 moves out of the bus bar protection piece 4, the bus bar inlet 403 corresponding to the moved cabinet output bus 101 is exposed, and the bus bar inlet 403 needs to be closed, so that impurities such as rainwater and dust are prevented from entering the bus bar protection piece 4. Based on this, the above-mentioned bus bar guard 4 includes a bus bar guard body 401 and a blocking plate 402, the bus bar inlet 403 is provided in the bus bar guard body 401, and the blocking plate 402 is used for closing the bus bar inlet 403 into which the inorganic cabinet output bus bar 101 extends. The number of plugging plates 402 is not greater than the number of bus inlets 403. The specific number of the plugging plates 402 is not limited in this embodiment, and is selected according to practical situations.

In some embodiments, as shown in fig. 5, the bus bar 3 includes a bus conductor 301, where the bus conductor 301 is used to correspond to each phase of current output by the first cabinet 1 one by one, and the bus conductor 301 is used to flow each phase of current. It will be appreciated that the cabinet output bus 101 also corresponds one-to-one to the respective phase currents output by the first cabinet 1. For example, if the first cabinet 1 outputs three-phase ac power, the bus bar 3 includes three bus conductors 301, and each bus conductor 301 corresponds to one phase of the three-phase ac power.

The bus conductor 301 includes at least two bus segments 3011 electrically connected in sequence, the bus segments 3011 are in one-to-one correspondence with the first cabinets 1, and each bus segment 3011 is used for electrically connecting with the cabinet output bus 101 of the corresponding first cabinet 1. It is understood that any two bus segments 3011 are distributed sequentially and electrically connected sequentially in the direction of current flow through the bus conductor 301.

Note that, the bus bar 3011 is provided with a bus bar connection structure 302, and the cabinet output bus bar 101 is connected at the bus bar connection structure 302. The bus connection structure 302 may include at least one connection hole or at least one other structure, which is not limited in this embodiment.

To facilitate electrical connection of the bus bar 3011, two adjacent bus bars 3011 may be selected to be electrically connected by lap joints, and the cabinet output bus 101 and bus bar 3011 may be electrically connected by lap joints. In practical situations, other ways of implementing the electrical connection are also selected, which is not limited in this embodiment.

Since the bus bar 3 is used to bus the output currents of the respective first cabinets 1, the magnitudes of currents flowing through different portions of the bus bar 3 are different. In order to reduce the cost of the bus bar 3, the cross-sectional area of one of any two bus bars 3011 located upstream is smaller than the cross-sectional area of one located downstream in the direction in which current flows through the bus conductor 301. It will be appreciated that the cross-section is perpendicular to the direction of current flow through the bus conductor 301, i.e. the area of the cross-section; in the direction in which current flows through the bus conductor 301, the current flowing through the upstream one of any two bus segments 3011 is smaller than the current flowing through the downstream one. In this way, the amount of the bus conductor 301 is reduced, thereby reducing the cost of the bus bar 3.

Taking the first cabinet 1 as three examples, the number of the bus bars 3011 is three, the three bus bars 3011 are respectively a first bus bar 3011a, a second bus bar 3011b and a third bus bar 3011c, in the direction of current flowing through the bus conductor 301, that is, in the direction of a straight arrow shown in fig. 5, the first bus bar 3011a, the second bus bar 3011b and the third bus bar 3011c are distributed in sequence, and the cross-sectional area of the first bus bar 3011a is smaller than the cross-sectional area of the second bus bar 3011b, and the cross-sectional area of the second bus bar 3011b is smaller than the cross-sectional area of the third bus bar 3011 c.

In some embodiments, as shown in fig. 6-9, in order to reduce the floor space, the cabinet output bus 101 may alternatively extend from the bottom end of the first cabinet 1, that is, the cabinet output bus 101 extends from the bottom end of the first cabinet 1 to the outside of the first cabinet 1, and the bus bar 3 and the bus bar guard 4 are both disposed at the bottom end of the first cabinet 1.

In this case, the integrated machine includes a cabinet parallel operation structure and an integrated platform 6, the cabinet parallel operation structure is integrated on the integrated platform 6, the integrated platform 6 is provided with a support assembly 7 for facilitating the setting of the bus bar 3 and the bus bar guard 4, and the first cabinet 1 is disposed on the support assembly 7. It will be appreciated that there is a gap between the first cabinet 1 and the integrated platform 6 which is able to accommodate the busbar shield 4.

In order to simplify the connection of the first cabinet 1 and the second cabinet 2, the input terminal 201 of the second cabinet 2 is disposed at a side of the second cabinet 2 close to the first cabinet 1, and the input end of the second cabinet 2 is close to the bottom end of the second cabinet 2. Since the bus bar 3 and the bus bar guard 4 are both located at the bottom end of the first cabinet 1, the portion of the bus bar 3 connected to the cabinet output bus bar 101 is lower than the input terminal 201, i.e., the bus conductor 301 is lower than the input terminal 201. In order to facilitate connection of the bus bar 3 and the input terminal 201, the bus bar 3 further includes: the bus bar comprises a first connecting conductor 303 and a second connecting conductor 304, wherein the first connecting conductor 303 and the second connecting conductor 304 are in one-to-one correspondence with the bus bar conductors 301, the first connecting conductor 303 and the second connecting conductor 304 are higher than the bus bar conductors 301, one ends of the bus bar conductors 301 and the second connecting conductor 304 are electrically connected with the first connecting conductor 303, and the other ends of the second connecting conductor 304 are electrically connected with the input terminal 201.

For simplicity of connection, the first connection conductor 303 may be chosen to be perpendicular to the second connection conductor 304, the first connection conductor 303 being perpendicular to the bus conductor 301, it being understood that the second connection conductor 304 is parallel to the bus conductor 301. Of course, the relative positional relationship of the first connection conductor 303, the second connection conductor 304, and the bus conductor 301 may be selected to be other, and is not limited to the above configuration.

On the basis of the above structure, the above-mentioned bus bar guard 4 may be selected to include a first guard 404, a second guard 405 and a third guard 406, which are hermetically connected in this order, for convenience of guard. It will be appreciated that the aforementioned bus bar shield body 401 includes a first shield 404, a second shield 405 and a third shield 406 that are sealingly connected in sequence.

The confluence inlet 403 is disposed on the first protection member 404, and the third protection member 406 is connected with the second cabinet 2 in a sealing manner; wherein the bus conductor 301 is in the first shielding member 404 and the second shielding member 405, the first connecting conductor 303 is located in the second shielding member 405, a portion of the second connecting conductor 304 is located in the second shielding member 405, another portion of the second connecting conductor 304 is located in the third shielding member 406, and the input terminal 201 extends into the third shielding member 406.

The first guard 404 is located at the bottom end of the first cabinet 1, and the second guard 405 and the third guard 406 are located at a side of the first cabinet 1 near the second cabinet 2.

The bus bar 3 generates heat during operation of the first cabinet 1 and the second cabinet 2. The heat dissipation of the bus bar 3 affects the current carrying capacity of the bus bar 3. In order to increase the current carrying capacity of the bus bar 3 to reduce the cost of the bus bar 3, it is necessary to place the bus bar 3 in a good heat dissipation environment. In some embodiments, the cabinet parallel operation structure further includes a heat dissipation structure for dissipating heat from the bus bar 3. The heat dissipation structure can be a heat dissipation air duct or a radiator and the like.

In order to simplify the structure, as shown in fig. 10 and 11, the heat dissipation structure is a heat dissipation air duct 10, and the bus bar 3 is located in the heat dissipation air duct 10. It will be appreciated that the cooling tunnel 10 has an air inlet 1001 and an air outlet 1002. In order to improve the heat dissipation effect, the cabinet parallel operation structure further comprises a fan 8 for driving air to flow through the heat dissipation air duct 10. The fan 8 is used for blowing or exhausting air, and thick arrow lines in fig. 11 are the air flowing directions.

Note that, if the fan 8 is used for blowing, as shown in fig. 10, the fan 8 is disposed at the air inlet 1001; if the fan is used for exhausting air, the fan 8 is arranged at the air outlet 1002.

In the case that the cabinet parallel operation structure includes the confluence protection piece 4, the confluence protection piece 4 forms the heat dissipation air duct 10, and the air inlet 1001 and the air outlet 1002 are both disposed on the confluence protection piece 4.

The bus bar protection member 4 includes a first protection member 404, a second protection member 405, and a third protection member 406, where the first protection member 404, the second protection member 405, and the third protection member 406 form the heat dissipation air duct 10, and one of the air inlet 1001 and the air outlet 1002 is disposed on the first protection member 404, and the other is disposed on the second protection member 405 or the third protection member 406.
