According to an embodiment of the utility model, a master control cabinet for a wind turbine generator system is provided. According to the scheme of the utility model, the main control cabinet for the wind generating set is divided into the front cavity and the rear cavity by the device mounting plate, the front cavity and the rear cavity are respectively opened in a front door opening mode and a side door opening mode, and electronic components with different levels are respectively arranged in the two cavities, so that the effects of optimizing the cable layout of the main control cabinet, reducing the cable consumption, facilitating maintenance and technical improvement, improving the electromagnetic interference resistance, fully and effectively utilizing the space and enabling the operation of operators to be convenient are realized. Hereinafter, embodiments of the present utility model will be described in detail with reference to the accompanying drawings.

Fig. 1 to 3 show a front view, a right view and a left view, respectively, of a master control cabinet for a wind power generation set according to an embodiment of the utility model. Fig. 4 is a cross-sectional view taken along line A-A of fig. 1. As shown, fig. 1 is a view of the front door with the cabinet removed, fig. 2 is a view with the right side plate of the cabinet removed, and fig. 3 is a view with the left side plate of the cabinet removed.

Referring to fig. 1 to 4, a master control cabinet for a wind power generation set includes: the cabinet 1, the first mounting plate 2, a front door (not shown), and a side door (not shown). The cabinet 1 is a generally rectangular parallelepiped mounting chamber having a rectangular parallelepiped shape. The cabinet 1 may include a frame, and back, top and bottom plates mounted on the frame. The first mounting plate 2 is provided inside the cabinet 1 to divide the cabinet 1 into a front chamber 11 and a rear chamber 12 (as shown in fig. 2 to 4). A front door is provided at a front side of the front chamber 11 for opening or closing the front chamber 11. Side doors are provided at the left and/or right sides of the rear chamber 12 for opening or closing the rear chamber 12.

Through separating the cabinet body into two cavities and opening through corresponding door, can arrange the electronic components of different grades respectively in two different cavity spaces, compare with the traditional master control cabinet of only opening the cabinet body from the qianmen for the degree of depth of cavity reduces, and the easy to assemble and maintenance personnel reach. The main control cabinet can open the rear cavity of the cabinet body from the side part, so that the operation of mounting, wiring, maintenance, technical improvement and the like of electronic components in the rear cavity is convenient. In addition, in the case that it is inconvenient to open the cabinet from the rear of the cabinet by a single side door, the main control cabinet of the present utility model can perform the above-described series of operations on the electronic components in the rear chamber by providing two side doors to open the rear chamber from the left and right sides, respectively.

According to an embodiment of the utility model, the cabinet 1 has a generally rectangular cross-section, and the first mounting plate 2 is arranged in a direction parallel to the long sides of the rectangle, and the first mounting plate may be used as a device mounting plate for mounting various components contained in the main control cabinet. Since the first mounting plates are arranged along the long side direction, the area of the mounting plates for mounting the devices is greatly increased, and a larger layout area is provided for mounting the electronic components. Compared with the scheme that the mounting plate is arranged near the rear part of the cabinet body in the traditional main control cabinet, the first mounting plate is arranged near the front part of the cabinet body, so that an operator can conveniently install and route the wiring operation, and the working time of the operation is effectively reduced. In addition, the main control cabinet body is compact in overall design, space in the cabinet body can be fully utilized, and the cabinet body cost is low.

The front door and the side door according to the embodiment of the present utility model are not particularly limited, and may be, for example, a single-leaf single-door or a double-leaf double-door, or may be any type of door that is opened and closed in other forms, as long as it can perform the related functions as the door of the main control cabinet of the present utility model.

Further, as an example, various buttons and indicator lights for controlling the circuits in the main control cabinet and/or an operation panel (e.g., a visualization panel, a touch screen, etc.) for controlling the various circuits may be provided on the front door and/or the side door. These arrangements facilitate the operator's manipulation of the electronic components within the master control cabinet from the outside without or with fewer openings to the corresponding door.

A left door is provided at the left side of the rear chamber 12 for opening the rear chamber 12 from the left side. A right door is provided on the right side of the rear chamber 12 for opening the rear chamber 12 from the right side. In the case where the cabinet 1 is wide, it is difficult to access the components mounted near the right side of the rear chamber from the left side of the cabinet 1, and also the components mounted near the left side in the rear chamber from the right side of the cabinet 1. The side doors are arranged on the left side and the right side of the cabinet body 1 at the same time, so that the components are more convenient to install and maintain.

Further, the minimum value of the predetermined length of the second mounting board depends on the minimum mounting area required for mounting the electronic components located in the rear chamber. The second mounting plate with proper height can be arranged according to the mounting requirement, the size of the space and the layout of each device by a person skilled in the art, so that the mounting space in the rear cavity can be saved, the cost of the mounting plate material can be saved, and the cost of the whole main control cabinet can be reduced.

By way of example, the height of the second mounting plate is less than the height of the rear chamber 12 so that the interiors of the rear chamber 12 are in communication with one another as a whole, facilitating connection of wiring between the various components. As an example, the second mounting plate may be fixed to the bottom plate of the rear chamber 12 such that an upper end of the second mounting plate is spaced apart from a top of the rear chamber by a predetermined distance, or the second mounting plate is fixedly coupled to the top of the rear chamber 12 such that a lower portion of the second mounting plate is spaced apart from a bottom of the rear chamber 12 by a predetermined distance. In addition, the second mounting plate may be fixed to the back of the first mounting plate 2 such that the upper and lower ends of the second mounting plate are spaced apart from the top and bottom of the rear chamber by a predetermined distance, respectively. In summary, the size and mounting location of the second mounting plate can be set by a person skilled in the art according to the mounting needs.

The left and right mounting plates 31 and 32 are mounted perpendicular to the first mounting plate 2 and are spaced apart in the left-right direction of the rear chamber 12. As an example, the left and right mounting plates 31 and 32 may be mounted parallel to the side door (as shown in fig. 2 and 3), or the left and right mounting plates 31 and 32 may be mounted inclined at a predetermined angle (e.g., an acute angle) with respect to the side door, or one of the left and right mounting plates 31 and 32 may be mounted parallel to the side door and the other may be mounted inclined at a predetermined angle (e.g., an acute angle) with respect to the side door. The specific manner of mounting the second mounting plate is not limited to the forms set forth herein.
