摘要
建立了多回交叉互联方式下电缆线路护套环流的计算模型,推导护套环流分布计算方法,并以某电力公司110 kV两回线路为例,建模计算了其在交叉互联方式下电缆线路3种不同相序排列时,两回路电缆的护套环流大小。计算结果表明,由于多回路电缆线路之间存在更强的电磁耦合关系,使得电缆电流分布的不均匀程度更为突出。
In this paper, the method of cable sheath circu- lation calculation model with cross connection style is estab- lished, and the sheath circulation distribution calculation method is deduced. Taking a 110kV dual-loop circuit as an example, models are established to calculate the dual-loop ca- ble sheath circulation with three kinds of different phase se- quences. The results show that because of the strong electro- magnetic coupling between the muhi-loop cable lines, the un- even distribution of the cable current is more prominent.
