浅谈改变高压单芯电缆金属护套接地方式降低能耗

高压单芯电缆金属护套不同的接地方式会对高压单芯电缆产生不同的运行效果，不正确的接地方式在遇到线路短路故障、雷击冲击及操作过电压时金属护套中会形成很高的感应电压，直接威胁人身和电缆的运行安全，同时，不正确的接地方式会在电缆金属护套中形成环流，电缆金属护套长期处在环流中会直接影响到电缆的载流量造成损耗电源电能。

Introduction to Change the High Voltage and Single-core Cable Metal Sheath Grounding Method Reduce the Loss of Power

different High voltage and single-core cable sheath grounding methods will have different running on high voltage single-core cable effect, improper grounding method in case of short circuit fault, lightning shock and operating over-voltage when metal can form high induced voltage in the sheath, threaten the safety of persons and the safe operation of the cable, at the same time, the improper grounding method will form the circulation in the cable metal sheath, the cable metal sheath in circulation for a long time can directly affect the carrying capacity of the cable loss caused by power supply electricity.
