[0023] See also Figure 1-4 The combiner cabinet 100 of this embodiment includes a cabinet body 11, which is formed with an opening 110 and a first accommodation space 111, a second accommodation space 112 and a third accommodation space 113 arranged in sequence from top to bottom in the vertical direction. The opening 110 is connected to the first accommodation space 111, the second accommodation space 112 and the third accommodation space 113 respectively, and each accommodation space is used to place different functional components.

[0024] The cabinet 11 is provided with a power distribution unit 12, a control unit 13 and a confluence unit 14. The power distribution unit 12 is arranged in the first accommodation space 111, the control unit 13 is arranged in the second accommodation space 112, and the confluence unit 14 is arranged in the third accommodation space 113. Different functional units are placed separately by dividing the accommodation space to avoid interference between the functional units, improve the reliability of the functional units, and facilitate maintenance.

[0025] Furthermore, in the junction cabinet, the distribution unit 12 includes distribution components such as circuit breakers, relays, and ACDC modules, which are used to distribute the collected electricity. The user needs to operate it at a high level, so it is placed in the first accommodation space 111 above. The junction unit 14 is less likely to be operated by the user, and it is mainly composed of exposed copper bars, which poses a greater safety risk. Therefore, it is placed in the third accommodation space 113 below, that is, close to the ground.

[0026] In this embodiment, the cabinet body 11 forms a storage space, and the storage space is provided with a first partition 151 and a second partition 152 arranged in a vertical direction, which has divided the storage space into a first storage space 111, a second storage space 112 and a third storage space 113. At least one of the first partition 151 and the second partition 152 can be movably arranged in the storage space of the cabinet body 11, for example, can be movably arranged in the storage space of the cabinet body 11 in the vertical direction and the horizontal direction. Specifically, at least one of the first partition 151 and the second partition 152 is movably arranged in the vertical direction in the accommodating space of the cabinet 11, and the corresponding accommodating space can be enlarged or reduced. For example, at least two slide grooves or slide rails arranged in the vertical direction are provided on the cabinet 11, and the partition is arranged on the slide grooves or slide rails, and can be moved up and down. The accommodating space formed by the partition and the cabinet and the accommodating space formed between the partitions can be changed in size. Furthermore, the slide grooves or slide rails extend in the horizontal direction, and the partition is arranged on the slide grooves or slide rails, so that it can be horizontally pulled out from the cabinet 11, that is, the partition is also movably arranged in the accommodating space in the horizontal direction, and the functional elements can be placed on the partitions, and the functional elements can be pulled out of the cabinet 11 for maintenance.

[0027] In other embodiments, at least one of the first partition 151 and the second partition 152 can be movably arranged in the vertical direction in the accommodation space of the cabinet 11. For example, at least two fixing members arranged in the vertical direction are provided on the cabinet 11, and the partition can be fixed with different fixing members according to the size requirements of the accommodation space, and the corresponding accommodation space can be enlarged or reduced. Among them, the fixing member can be, for example, a card slot, and a buckle is provided on the corresponding partition, and the card slot and the buckle are engaged to fix it.

[0028] In other embodiments, at least one of the first partition 151 and the second partition 152 can be arranged in the accommodation space of the cabinet 11 so as to be movable only in the horizontal direction. For example, a slide groove or a slide rail corresponding to the movable partition is arranged on the cabinet 11, and the slide groove or the slide rail extends in the horizontal direction. The partition is arranged on the slide groove or the slide rail, so that the movable extraction in the horizontal direction can be realized. The number of the slide grooves or the slide rails can correspond to the number of the movable partitions.

[0029] Specifically in this embodiment, the second partition 152 is movably arranged on the cabinet 11 only in the horizontal direction, and the control unit 13 is arranged on the second partition 152. The control unit 13 includes a UPS (uninterruptible power supply) host. When the user needs to inspect or repair the UPS host, the second partition 152 can be pulled out to facilitate operation of the UPS host.

[0030] Further, according to the specific conditions of the functional components, in this embodiment, the first partition 151 is fixedly arranged on the cabinet 11. Since the power distribution unit 12 has a large number of power distribution components and a small volume compared to other units, and there are many and complicated wirings, the movable setting of the first partition 151 is not conducive to user operation, so the first accommodating space 111 is set as a fixed space, and the first partition 151 is fixedly arranged.

[0031] The combiner cabinet 100 further includes a first cabinet door 161 and a second cabinet door 162, both of which are disposed on the cabinet body 11 to close the opening of the cabinet body 11.

[0032] The opening 110 includes a first sub-opening 1101 and a second sub-opening 1102, the first sub-opening 1101 is connected to the first accommodating space 111, and the second sub-opening 1102 is respectively connected to the second accommodating space 112 and the third accommodating space 113, the size of the first sub-opening 1101 in the vertical direction is greater than or equal to the size of the second sub-opening 1102 in the vertical direction, the first cabinet door 161 is movably connected to the cabinet body 11 to open or close the first sub-opening 1101, and the second cabinet door 162 is movably connected to the cabinet body 11 to open or close the second sub-opening 1102.

[0033] The third accommodating space 113 is provided with a confluence unit 14, which is prone to the risk of high voltage electricity, so an electromagnetic lock is provided for the second cabinet door 162, and a battery management module BMS is provided in the control unit 13, and the battery management module BMS is connected to the electromagnetic lock. When the confluence unit 14 is working, the electromagnetic lock is controlled to be locked to prevent it from being opened; only when the confluence unit 14 stops working, the electromagnetic lock is controlled to be opened, so that the second cabinet door 162 can be opened. The electromagnetic lock is provided to ensure the safety of the confluence cabinet 100 and avoid the risk of electric shock.

[0034] The first cabinet door 161 is disposed corresponding to the first accommodating space 111 , and is operated more by users than the second cabinet door 162 , so a human-machine interactive display screen 1611 and an indicator light 1612 are also disposed on the first cabinet door 161 .
