DETAILED DESCRIPTION

[0050] The core of the utility model is to disclose a cabinet to improve the space utilization rate inside the converter.

[0051] Another core of the utility model is to disclose a converter including the above cabinet.

[0052] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions of the utility model described in the claims. It should be noted that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings. In the absence of conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0053] In the existing configuration scheme, the converter is equipped with an independent main control cabinet so that the main control integrated machine can be compatible with the non-main control integrated machine. That is to say, in the absence of the main control system, the main control cabinet will be empty, which causes space waste inside the converter with limited space. In addition, for the non-main control integrated machine, the independent main control cabinet not only increases the volume of the converter, but also increases the cost. Based on this, the utility model discloses the following technical solution.

[0054] Combination Figure 1-Figure 13 The cabinet disclosed in the utility model includes a main cabinet 100 and a sub-cabinet 200. The main cabinet 100 has a main space for storing a first component, and a door opening 101 for connecting the main space with the outside is opened on the cabinet body of the main cabinet 100. The first component in the main cabinet 100 can be repaired, inspected, etc. at the door opening 101. The sub-cabinet 200 can be detachably arranged on the main cabinet 100 and can cover the door opening 101. The sub-cabinet 200 has a sub-space for storing a second component.

[0055] Taking the storage of AC devices as an example, the main cabinet 100 can store AC devices without main control, and the sub-cabinet 200 can be used as a control cabinet for AC devices, and can be customized according to the needs of different users. The main cabinet 100 and the sub-cabinet 200 are independent of each other. The main cabinet 100 can be used as a platform-based, standardized cabinet body. Some parts of the sub-cabinet 200 are universally designed, and the other parts are customized. For designers, they only need to design the customized part according to user requirements, which greatly saves the workload of designers and improves work efficiency. And according to actual maintenance needs, users can remove the sub-cabinet 200 from the main cabinet 100, which is convenient for users to repair the first component in the main cabinet 100 at the door opening 101.

[0056] Compared with the prior art, the cabinet disclosed in the utility model has the following beneficial effects:

[0057] (1) The main cabinet 100 and the auxiliary cabinet 200 are independent of each other. For converter manufacturers, a large number of main cabinets 100 and auxiliary cabinets 200 can be prepared as customized cabinets. In addition, the main cabinet 100 can be assembled and stored online first, and then the auxiliary cabinet 200 can be reworked online to add a specific order, which can greatly shorten the delivery cycle.

[0058] (2) The main cabinet 100 and the auxiliary cabinet 200 are detachable, so that the auxiliary cabinet 200 can be configured or removed on the main cabinet 100 according to actual conditions, thereby saving the assembly space inside the wind turbine tower, reducing the packaging size of the converter, facilitating transportation, and reducing costs.

[0059] (3) The customized design of some components of the sub-cabinet 200 can meet the use in various scenarios, which not only saves the internal space of the cabinet and reduces space waste, but also can meet the needs of different users.

[0060] (3) It is convenient for users to make functional changes later. For example, if a non-main control integrated machine is changed to a main control integrated machine, it is only necessary to add a sub-cabinet 200 on the basis of the original converter and use it as an energy storage cabinet, transformer cabinet, etc., without having to purchase a new converter. The cabinets are easy to assemble and highly operable, which improves the utilization rate of the original converter and greatly saves the cost of purchasing a new converter.

[0061] (4) The door opening 101 provides a maintenance position different from that of a conventional cabinet, making it convenient for users to repair the first component at different positions.

[0062] Combination Figure 1The cabinet body of the main cabinet 100 is provided with a conventional cabinet door, which is a prior art and will not be described in detail here. In one embodiment, the main cabinet 100 further comprises a main cabinet door, which is hinged to the cabinet body of the main cabinet 100. With the rotation of the main cabinet door, the main cabinet door can cover the door opening 101 or expose the door opening 101. The auxiliary cabinet 200 is detachably arranged on the main cabinet door. With the rotation of the main cabinet door relative to the cabinet body of the main cabinet 100, the auxiliary cabinet 200 can cover or expose the door opening 101 accordingly.

[0063] Specifically, the sub-cabinet 200 includes a sub-cabinet body 210 and a cabinet door body 220. The sub-cabinet body 210 is detachably arranged on the main cabinet door; the cabinet door body 220 is rotatably arranged on the sub-cabinet body 210 (through the second hinge 213 and other components), and is enclosed with the sub-cabinet body 210 to form a sub-space. The function panel 221 can be fixed on the cabinet door body 220 by bolts, rivets, etc. according to actual conditions. A device installation plate 215 is usually also arranged in the space of the sub-cabinet 200 for installing electronic components such as main control devices.

[0064] It is understandable that different whole machine factories have different layouts of main control devices and door panel indicator lights due to differences in main control functions. Therefore, the sub-cabinet 200 includes a basic part and a configuration part. The basic part includes the above-mentioned sub-cabinet body 210 and the cabinet door body 220, which serve as the common structural parts of the sub-cabinet 200; the configuration part includes a function panel 221 and a device mounting plate 215, which can be customized according to different user needs.

[0065] It is understandable that the main cabinet door may not be provided, but the auxiliary cabinet 200 may be directly hingedly provided at the door opening 101 of the main cabinet 100. Figure 2 and Figure 3 The main cabinet 100 has a door opening 101 on its side wall, and the auxiliary cabinet 210 is hingedly arranged on the cabinet side wall to close the door opening 101. The auxiliary cabinet 200 can be rotated to open relative to the main cabinet 100 so that the door opening 101 is exposed, and side maintenance and inspection of components such as the AC in the main cabinet 100 can be performed at the door opening 101.

[0066] The first side of the auxiliary cabinet 210 is connected to the cabinet side wall by a hinge ( Figure 3 The second side of the auxiliary cabinet 210 may be detachably connected to the cabinet side wall by bolts, or the second side of the auxiliary cabinet 210 may be provided with a Figure 3 The L-shaped baffle 214 is detachably fixed to the cabinet side wall of the main cabinet 100 by means of connecting parts such as rotating buckles and bolts.

[0067] In order to ensure the sealing performance, Figure 2 and Figure 3, a first sealing member 211 such as a sealing strip is provided on at least one of the cabinet side wall of the main cabinet 100 and the auxiliary cabinet 210 (or the main cabinet door) to ensure the sealing of the door opening 101 of the main cabinet 100 and the connection between the auxiliary cabinet 200. Specifically, the first sealing member 211 can be fixedly provided on the cabinet of the main cabinet 100, or can be fixed on the auxiliary cabinet 210 of the auxiliary cabinet 200. In addition, a second sealing member 222 such as a sealing strip is provided at the opening and closing position of the cabinet door body 220 and the auxiliary cabinet 210 to ensure the sealing of the auxiliary space, and the second sealing member 222 can be fixed on the auxiliary cabinet 210 or the cabinet door body 220 of the auxiliary cabinet 200.

[0068] The main cabinet 100 and the sub-cabinet 200 can be two independent cabinets that do not affect each other, so that the sub-cabinet 200 can be easily configured on the main cabinet 100 according to needs, and the sub-cabinet 200 can be directly removed from the main cabinet when the sub-cabinet 200 is not needed.

[0069] In one embodiment, the main cabinet 100 includes a plurality of enclosure panels and configuration panels, the enclosure panels enclose to form a main space, or the configuration panel replaces one of the enclosure panels, and together with the remaining enclosure panels enclose to form the above-mentioned main space, and the configuration panel is detachably connected to the enclosure panels, the sub-cabinet 200 is detachably arranged on the configuration panel, and the configuration panel is provided with the above-mentioned door opening 101 (the main cabinet door is detachably arranged on the configuration panel). In this embodiment, when the sub-cabinet 200 is not needed, the main cabinet 100 formed by the enclosure panels is directly used, and when the sub-cabinet 200 is needed, the enclosure panels at the positions corresponding to the configuration panels on the main cabinet 100 can be removed and replaced with configuration panels with the sub-cabinet 200, so that the cabinet has both the main cabinet 100 and the sub-cabinet 200.

[0070] The configuration plate is provided with the above-mentioned door opening 101, so as to facilitate maintenance of the components on the side of the converter when the cabinet is equipped with a sub-cabinet 200; when the cabinet does not include the sub-cabinet 200, the enclosure plate at the position corresponding to the configuration plate is detachably connected to the other enclosure plates, so as to facilitate removal of the enclosure plate to maintain the components on the side of the converter. In addition, the existence of the door opening 101 also facilitates heat exchange of the airflow in the main space and the sub-space.

[0071] In a specific application scenario, there are multiple main cabinets 100 , and a sub-cabinet 200 is disposed on one or more of the main cabinets 100 .

[0073] The working performance of the components in the main cabinet 100 is easily affected by the temperature. Considering the heat dissipation of the components in the main cabinet 100, a main cabinet heat dissipation mechanism 110 for heat dissipation is provided in the main space of the main cabinet 100. At the same time, in order to ensure the heat dissipation performance of the components in the sub-cabinet 200, the main space and the sub-space can be connected, so that the components in the sub-cabinet 200 can be cooled by the main cabinet heat dissipation mechanism 110. Alternatively, a sub-cabinet heat dissipation mechanism 230 can be provided in the sub-space of the sub-cabinet 200, and the components in the sub-cabinet 200 are cooled by the sub-cabinet heat dissipation mechanism 230, and the heat dissipation of the main cabinet 100 and the sub-cabinet 200 do not affect each other.
