摘要
传统的接地装置耐腐蚀能力差,使用寿命短,安全性能低,维护成本高。本文介绍了用铜包钢做成接地体和接地线,使接地装置全部组成元件都具有铜材的良好抗自然腐蚀能力的免维护的接地装置,分析了其保障人身安全、设备安全和电力系统安全的优越性。在此基础上,提出了免维护接地装置的制造工艺和设计要求,并对其应用前景进行了展望。
Traditional earthing devices have worse corrosion resistance, short service life, low safety performance and high maintenance cost. The paper introduces earthing bodies and earthing wires made of copper clad steel, thereby all elements of the earthing device are maintenance-free devices with excellent natural corrosion resistance ability of copper materials, the excellence in the aspects of guarantee personnel safety, equipment safety and power system safety can be analyzed. Manufacture technique and design requirements of maintenance-free earthing device are proposed on the basis, and its application prospect is expected.
