针对在不同铺设条件下研究海底电缆三相单芯和分相铅包海底电缆载流量计算方法,编写相应计算程序,得到在不同铺设条件下的电缆载流量。根据研究表明电缆的载流量超过额定值10%,电缆的寿命将减小一半,因而电缆载流量的控制,对于提高输电可靠性和延长电缆的使用寿命均具有重要意义。本文主要是针对具体型号的电缆在不同敷设条件下,分别研究三相单芯和分相铅包海底电缆载流量计算方法,编写相应计算程序,得到在不同敷设条件下的电缆载流量。
Aiming at the calculation method of the submarine cable three-phase single-core and the submarine lead submarine cable under different laying conditions, the corresponding calculation program is compiled and the cable current carrying capacity under different laying conditions is obtained. According to the research shows that the current carrying capacity of the cable exceeds 10% of the rated value, the service life of the cable will be reduced by half. Therefore, the control of the current carrying capacity of the cable is of great significance for improving the transmission reliability and prolonging the service life of the cable. In this paper, the method of calculating the current carrying capacity of three-phase single-core and split-phase submarine cables under different laying conditions is studied for different types of cables. Corresponding calculation programs are prepared and the current carrying capacity under different laying conditions is obtained.
