厦门电力进岛自容式充油海底电缆供油系统设计

Design of the Oil Supply System of Self-Contained Oil-Filling Submarine Cable in Electricity for Xiamen Islands Project

依托厦门电力进岛第一通道扩建工程,计算了自容式充油海底电缆的需油量、油压值,并通过利用供油箱内的油体积、温度和压力的状态方程,提出了该类海缆供油系统油压整定的计算方法,并依此制定了该类海缆油压报警的整定原则,为该类海缆的施工、运行提供了基础数据。

Based on the experience of the first channel extension of the Electricity to Xiamen Islands Project, this paper calculates the oil demand and oil pressure of the self-contained oil-filling submarine cable. Using the equation of state from the oil supply tank volume, temperature and pressure, the paper proposes the calculation method for the pressure setting of the oil supply system, and furthermore formulates the cable oil pressure alarm setting principle and provides the basic data of the construction and operation of the submarine cable.
