    摘 要:目前國內(nèi)桿塔或其他電力設(shè)施的接地引下線均未做防腐措施處理,對電力系統(tǒng)的安全運行造成極大隱患。提出了可用于變電站及輸電線路接地引下線的腐蝕狀態(tài)監(jiān)測方法,并設(shè)計了基于密封氣壓檢測的引下線腐蝕狀態(tài)監(jiān)測裝置,將中空充氣密封狀態(tài)的腐蝕單元與接地引下線一同埋入土壤中,且與接地引下線保持電氣連接,保證監(jiān)測裝置與接地引下線在同樣的土壤環(huán)境中發(fā)生腐蝕,且具有同樣大小的通流。通過制作實驗室模型及可行性試驗,驗證了該裝置可實現(xiàn)免開挖接地引下線腐蝕狀態(tài)的監(jiān)測功能。

    Abstract: At present, the grounding down conductors of poles or other power facilities in China have not been treated with anti-corrosion measures; it causes great hidden dangers to the safe operation of the power system. In this paper, a corrosion state monitoring method that can be used for grounding down conductors of substations and transmission lines is proposed, and a corrosion state monitoring device for down conductors based on sealing air pressure detection is devised, that is bury the corrosive unit in a hollow, air-filled and sealed state together with the ground down conductor into the soil, and maintain electrical connection with the ground down conductor, and moreover it should ensure that the monitoring device and the ground down conductor are corroded in the same soil environment, have the same flow through. A laboratory model is made to carry out feasibility test, which verifies that the device can realize the monitoring function of the corrosion status
of grounding lead down without excavation.
    Key words: ground lead-in line; anti-corrosion measure; corrosion monitoring; excavation free
