摘要
接地装置埋于地下,极易被腐蚀,且腐蚀和断点的检查、修护困难。分析接地装置的腐蚀原理,介绍接地装置腐蚀速度预评估方法,为其布设、选材和防腐设计提供依据。
The earth-termination system is buried underground and is corroded easily; the inspection and repair of corrosion and broken points of the earth-termination system are difficult. Corrosion principles of the earth-termination system are analyzed;methods for pre-evaluation on the corrosion speed of the earth-termination system are introduced, providing a basis for layout, material selection and anticorrosion design of the earth-termination system.
