Description
技术领域 technical field
本实用新型涉及一种分解槽的供电装置，属于氧化铝分解槽的供电技术领域。The utility model relates to a power supply device for a decomposition tank, which belongs to the technical field of power supply for an alumina decomposition tank.
背景技术 Background technique
氧化铝厂分解槽为一类负荷供电，在生产过程中，分解槽是不允许断电的，所以分解槽的配电设计常采用从配电室低压柜I段和II段母线形成双电源，向各分解槽供电箱供电。目前，分解槽系列的供电通常根据规模将分解系列分成几组，每组单独供电，各组中分解槽又使用单独的自动开关控制。考虑备用电源时，使用的设备和电缆就成倍的增加，接线也更复杂。如果以40万吨的规模为例，每个分解槽系列中有15个分解槽，采用现有的供电方式，如果将15个分解槽分成两组，一组8个，另一组7个，每组需要一个低压柜，则需要两个低压柜，每个分解槽配置一个自动开关，则需要15个自动开关，再考虑备用电源，则需要4台低压柜，30个自动开关，电缆和母线的用量也大大增加，线路敷设也复杂，投资大。因此，现有的分解槽的供电方式还是不够理想。The decomposition tank of the alumina plant supplies power for a class of loads. During the production process, the decomposition tank is not allowed to be powered off. Therefore, the power distribution design of the decomposition tank often adopts the dual power supply from the busbars of the low-voltage cabinet in the power distribution room I and II. Supply power to each decomposition tank power supply box. At present, the power supply of the decomposition tank series is usually divided into several groups according to the scale, and each group is powered separately, and the decomposition tanks in each group are controlled by a separate automatic switch. When considering backup power, the equipment and cables used are multiplied and the wiring is more complicated. Taking the scale of 400,000 tons as an example, there are 15 decomposition tanks in each decomposition tank series, and the existing power supply method is used. If the 15 decomposition tanks are divided into two groups, one group has 8 and the other group has 7, Each group needs one low-voltage cabinet, then two low-voltage cabinets are needed, and each decomposition tank is equipped with an automatic switch, then 15 automatic switches are needed, and considering the backup power supply, four low-voltage cabinets, 30 automatic switches, cables and busbars are needed The amount of electricity has also increased greatly, and the laying of lines is also complicated and the investment is large. Therefore, the power supply mode of the existing decomposition tank is still not ideal enough.

具体实施方式 Detailed ways
下面结合附图和实施例对本实用新型作进一步的说明，但不作为对本实用新型的限制。The utility model will be further described below in conjunction with the accompanying drawings and embodiments, but not as a limitation of the utility model.
本实用新型的实施例，如附图1所示，它由两个完全相同的配电电路组成，两个配电电路互为备用；各配电电路中包括低压柜1，低压柜1中设有两个自动开关2，各自动开关2上连接有出线电缆3，各出线电缆3分别连接至两个各自独立的接线箱4，各接线箱4中的出线电缆3分别与分支母线5连接，分支母线5分别与设在各个分解槽附近的供电箱6连接即成。在实施时，其低压柜1、自动开关2、接线箱4均可采用市场上出售的成品进行安装。The embodiment of the present utility model, as shown in accompanying
本实用新型的工作原理是采用两个完全相同的配电电路互为备用形成双电源为分解槽系列供电，附图1的上半部份是一个供电电路，附图1的下半部份是和上半部份完全相同的另一个供电电路，两个供电电路互为备用。下面以40万吨规模的氧化铝生产线为例，对本实用新型做详细说明，40万吨规模的氧化铝分解系列中有15个分解槽，将15个分解槽分成A组和B组，A组有8个分解槽，B组有7个分解槽，其供电电路设置一个低压柜1，低压柜1中设有两个自动开关2，一个自动开关2控制一组分解槽，自动开关2的进线与开关柜母线连接，两个自动开关的出线端分别经出线电缆3连接到两个独立的接线箱4中，在接线箱4中，出线电缆3与分支母线5连接，一个接线箱4中引用的分支母线5为A组的8个分解槽供电，另一个接线箱4中引出的分支母线5为B组的7个分解槽供电，每条分支母线5仅为一组分解槽供电，在各组分解槽的每个分解槽附近设置供电箱6，每个供电箱6分别接在分支母线5上。The working principle of the utility model is to use two identical power distribution circuits as backup to each other to form a dual power supply to supply power to the decomposition tank series. The upper part of the accompanying
考虑到氧化铝的分解槽需要双电源供电，所以以上电路需要两套互为备用，因此所需要的设备和材料也各自需要两套。Considering that the aluminum oxide decomposition tank needs dual power supply, so the above circuits need two sets for mutual backup, so the required equipment and materials also need two sets respectively.
在设备及材料的选用上，主要根据各组分解槽的计算电流确定。低压柜中的自动开关选用整定值800A的自动开关、出线电缆选用(3×150+1×70)的电缆，分支母线的型号为ZR-YJV-4(1×400)/4(1×50)。In the selection of equipment and materials, it is mainly determined according to the calculated current of each component decomposition tank. The automatic switch in the low-voltage cabinet adopts the automatic switch with a setting value of 800A, the outgoing cable selects (3×150+1×70) cable, and the model of the branch bus is ZR-YJV-4(1×400)/4(1×50 ).
