摘要
海洋石油开发中一般在中心平台设置电站,通过海底电缆给井口平台供电,随着开发规模不断扩大,长距离海缆应用越来越多,有些海缆长度达30km。海缆空载或轻载合闸瞬间线路电容充电功率很大,导致海缆末端电压升高,严重时会损伤或击穿海缆;文昌13-6项目在海缆末端平台设置并联电路器,与海缆直接连接,补偿长距离输电线路的容性充电电流,抑制工频过电压,保证线路的可靠运行,达到海缆保护的目的。
Offshore oil is usually installed in the central platform power station,through the submarine cable to the wellhead platform power supply,with the development scale continues to expand,more and more long-distance cable applications,some cable length of 30 km.Cable submarine no load or light load closing moment Line capacitor charging power is very large,resulting in submarine cable terminal voltage increases,serious damage or breakdown of the submarine cable;this project（Wenchang 13-6 project）in the submarine cable terminal platform Parallel circuit breaker,direct connection with the sea cable to compensate for longdistance transmission line capacitive charging current,inhibit the power frequency over-voltage,to ensure reliable operation of the line to achieve the purpose of submarine cable protection.
