背景技术 Background technique
光伏/风力并网发电技术是可再生能源技术发展的重要组成部分，近几年也获得了长足发展，部分技术实现了商业化，但仍然存在一些不足之处。特别是在大功率并网发电的应用中，由于电器设备均较大，一般的电源机柜难以满足存放的要求，于是目前就使用户外房房体来放置这些较大的电器部件，占用了较大的放置空间。现有的大功率光伏逆变器的集成并柜采用的是两台大功率逆变器分别配有单独的直流配电柜，同时，还配有一台交流输出柜，外加一台配电柜，一共是六个柜体，占用空间较大，内部接线繁琐，且只能在施工现场接线。 Photovoltaic/wind grid-connected power generation technology is an important part of the development of renewable energy technology. It has also achieved considerable development in recent years, and some technologies have been commercialized, but there are still some shortcomings. Especially in the application of high-power grid-connected power generation, due to the large electrical equipment, the general power supply cabinet is difficult to meet the storage requirements, so at present, the outdoor room is used to store these larger electrical components, which takes up a lot of space. placement space. The existing integrated combination of high-power photovoltaic inverters uses two high-power inverters equipped with separate DC power distribution cabinets. At the same time, it is also equipped with an AC output cabinet and an additional power distribution cabinet. There are six cabinets, which take up a lot of space, and the internal wiring is cumbersome, and can only be wired at the construction site.
实用新型内容 Utility model content
本实用新型的目的在于提供一种节约占地空间、成本低的大功率光伏逆变器的集成并柜。 The purpose of the utility model is to provide a space-saving and low-cost high-power photovoltaic inverter integrated cabinet combination.
为实现上述目的，本实用新型采用了以下技术方案：一种大功率光伏逆变器的集成并柜，包括第一、二逆变器单元，第一、二逆变器单元的旁侧分别放置直流配电柜和综合柜，所述的直流配电柜由第一、二直流配电柜组成，所述的综合柜由交流输出柜和配电柜组成。 In order to achieve the above purpose, the utility model adopts the following technical solutions: an integrated cabinet of high-power photovoltaic inverters, including the first and second inverter units, and the sides of the first and second inverter units are respectively placed A DC power distribution cabinet and a comprehensive cabinet, the DC power distribution cabinet is composed of the first and second DC power distribution cabinets, and the comprehensive cabinet is composed of an AC output cabinet and a power distribution cabinet.
由上述技术方案可知，本实用新型将原来的两个直流配电柜合并为一个直流配电柜，并将交流输出柜与配电柜放置于一个综合柜柜体内，使原本的六个柜体直接减少为四个柜体，大大减小了集成并柜柜体的占地空间，降低了集成并柜的生产成本。 It can be seen from the above technical scheme that the utility model combines the original two DC power distribution cabinets into one DC power distribution cabinet, and places the AC output cabinet and the power distribution cabinet in a comprehensive cabinet, so that the original six cabinets It is directly reduced to four cabinets, which greatly reduces the floor space of the integrated cabinet body and reduces the production cost of the integrated cabinet.

具体实施方式 Detailed ways
一种大功率光伏逆变器的集成并柜，包括第一、二逆变器单元1、2，第一、二逆变器单元1、2的旁侧分别放置直流配电柜3和综合柜4，所述的直流配电柜3由第一、二直流配电柜组成，所述的综合柜4由交流输出柜和配电柜组成。如图2所示。 An integrated cabinet combination of high-power photovoltaic inverters, including first and second inverter units 1 and 2, and a DC power distribution cabinet 3 and an integrated cabinet are respectively placed on the sides of the first and second inverter units 1 and 2 4. The DC power distribution cabinet 3 is composed of the first and second DC power distribution cabinets, and the integrated cabinet 4 is composed of the AC output cabinet and the power distribution cabinet. as shown in picture 2.
如图2所示，所述的直流配电柜3、第一逆变器单元1、第二逆变器单元2以及综合柜4依次并排紧密放置在房体8内。所述的第一、二直流配电柜左、右并排布置在直流配电柜3柜体内；所述的交流输出柜位于综合柜4柜体的下方，配电柜位于综合柜4柜体的上方。本实用新型将原来的两个直流配电柜合并为一个直流配电柜3，并将交流输出柜与配电柜放置于一个综合柜4柜体内，使原本的六个柜体直接减少为四个柜体，大大减小了集成并柜柜体的占地空间。 As shown in FIG. 2 , the DC power distribution cabinet 3 , the first inverter unit 1 , the second inverter unit 2 and the integrated cabinet 4 are placed side by side closely in the room body 8 in sequence. The first and second DC power distribution cabinets are arranged side by side in the DC power distribution cabinet 3 on the left and right; the AC output cabinet is located below the integrated cabinet 4 cabinet, and the power distribution cabinet is located in the integrated cabinet 4 cabinet above. The utility model combines the original two DC power distribution cabinets into one DC power distribution cabinet 3, and places the AC output cabinet and the power distribution cabinet in a comprehensive cabinet 4, so that the original six cabinets are directly reduced to four A cabinet, greatly reducing the space occupied by the integrated cabinet.
如图2所示，所述的直流配电柜3的出线端引出直流引线5，直流配电柜3的出线端通过直流引线5分别与第一、二逆变器单元1、2的直流接线侧相连；所述的综合柜4的进线端引出交流引线6，综合柜4的进线端通过交流引线6分别与第一、二逆变器单元1、2的交流接线侧相连。所述的直流引线5和交流引线6均位于走线桥架7上开设的线槽内，大大方便了现场的接线安装。 As shown in Figure 2, the outlet end of the DC power distribution cabinet 3 leads to a DC lead wire 5, and the outlet end of the DC power distribution cabinet 3 is respectively connected to the DC connections of the first and second inverter units 1 and 2 through the DC lead wire 5. side connection; the incoming line end of the integrated cabinet 4 leads to the AC lead wire 6, and the incoming line end of the integrated cabinet 4 is connected to the AC wiring side of the first and second inverter units 1 and 2 respectively through the AC lead wire 6. Both the DC leads 5 and the AC leads 6 are located in wire slots on the wiring bridge 7, which greatly facilitates on-site wiring installation.
