摘要
电力电缆是传输和分配电能的一种特殊电线,由于运行可靠,节约空间,维护工作量小,不需频繁的巡视而广泛、大量地被应用于发电厂及变电站的接线中。而电缆线路一旦出现故障,多数是永久性故障,故障隐蔽,不易查找,时间越长,危害越大,如不及时采取措施,就会危及其余线路,甚至造成母线失压,影响电网安全。
The electric cable is a special wire for transmission and distribution of electric energy. Due to the reliable operation, space- saving, small maintenance workload and without frequent inspections and extensive, the electric cable is widely used in power plants and substations wiring. Once the failure of cable line happens, most of which are permanent fault, the fault is hidden and difficult to find, and the longer the duration, the greater the harm. If we do not take measures timely, it will endanger the rest of the line, and even cause the bus lost pressure, and affect grid security.
