摘 要：合理地選擇電纜截面可提高配電系統(tǒng)安全性，減少事故隱患。結合AP1000核電工程實踐，從電纜載流量、抗短路能力、電壓損失、投資和運行的經(jīng)濟性等角度介紹了AP1000核電廠電力電纜截面選擇的原則及有效方法，通過對載流量、敷設環(huán)境、電壓降等因素計算分析后，得出不同敷設環(huán)境中針對不同負荷類型的電力電纜截面選擇表，為后續(xù)核電工程設計與完善提供了借鑒。

Abstract: The reasonably selection of power cable section could raise the security of power distribution system and reduce accidents potential. Combining with AP1000 nuclear power engineering practice, introduction was made to the principle and effective way of power cable section selection of AP1000 nuclear power plant from the corner of power cable carrying capacity, anti-short-circuit capacity, voltage loss, economy of investment and operation, and so on. After the analysis and calculation of carrying capacity, laying environment and voltage drop etc factors, this paper obtained power cable section option lists of different load types for different laying environment, which provides references for the power cable sizing design in other nuclear power plant.
Key words: nuclear power plant; power cable; section; cable laying
