摘 要：針對海陽核電一期工程現(xiàn)場出現(xiàn)了大截面動(dòng)力電纜在電機(jī)接線盒內(nèi)無法端接施工的問題，介紹了美國標(biāo)準(zhǔn)和國家標(biāo)準(zhǔn)選擇電纜的不同計(jì)算過程，對比了標(biāo)準(zhǔn)之間的差異，并對產(chǎn)生端接問題的原因進(jìn)行了分析，提出通過更換接線盒、增加轉(zhuǎn)接箱等措施來解決端接問題。
關(guān)鍵詞：電纜端接；電纜截面；壓降校核；資料交換

Abstract: In allusion to the problem that in Haiyang nuclear power project site the power cable with big section can not terminate in motor junction box, this paper introduced the different computational process of power cable selection between American standard and national standard and compared the differences between the standards. The cause producing the terminating problem was carried out analysis. This paper proposed to change the junction box to increase the transfer box etc measures to solve the terminating problem.
Key words: cable terminal; cable section; voltage drop check; data exchange
