摘要
导体温度是电缆运行非常重要的参数之一,讨论了海南联网系统500 k V海底电缆温度在线监测方式,介绍了利用布里渊散射分布式测量海底电缆表面温度的原理,结合IEC 60287标准中的内容,对热阻计算进行了优化,从而依据海缆表面的温度推导出导体的温度,实现海底电缆导体温度的实时分布式监测。
The conductor temperature of the cable is an extremely important parameter when it is being running. It is presented the principle of the distributed measurement of the surface temperature of the submarine cable with the theory of Brillouin scattering; and then it references the standard of IEC60287,optimizes the computing method of the thermal resistance,and then deduces the conductor temperature by the surface one,so to achieve distributed monitoring of the conductor temperature of the submarine cable in real time.
