利用开关柜二次仪表室的新型二次电缆敷设方法

Novel Cable Laying Method Using the Instrument Room in Switch Cabinet

提出了一种利用开关柜二次仪表室的新型二次电缆敷设方法。该种方法充分利用了开关柜的二次仪表室空间,将每个开关柜柜体隔板在二次仪表室位置开孔贯通,形成一条连续的、沿着整个开关柜柜体敷设的通道。相比常规的电缆沟和电缆层敷设方法,该种方法显著减少了二次电缆的上下走线和开关柜底部的二次开孔数,有效减少了电缆用量和工程投资,并真正实现了高、低压电缆的敷设分离,具有经济效益好、敷设方便、可靠性高等优点。

A novel secondary cable laying method using the secondary instrument room of switch cabinet is proposed.The partition board of each switch cabinet is perforated at the position of the secondary instrument room to form a continuous channel laid along the whole switch cabinet.Compared with the conventional cable trench and cable layer laying method,this method significantly reduces the up and down routing of secondary cables and the number of secondary openings at the bottom of the switchgear,effectively reducing the cable consumption and engineering investment.At the same time,this method truly realizes the laying separation of high and low voltage cables,and has the advantages of good economic benefits,convenient laying and high reliability.
