海洋石油平台上的各类电气设备的工作环境较为恶劣,潮湿的工作环境对设备的绝缘能力造成了很大的影响,经历风水日晒,设备极易发生漏电现象。由于海洋平台的特殊性质,一旦发生设备漏电问题,造成的损失不可估量,因此在设备安装及维护时,要格外注意。本文对海洋石油平台的电气设备漏电保护措施进行简单分析,研究了常用的中性点不接地系统的漏电保护措施,探讨了漏电保护器在海洋石油平台上的应用。 Offshore oil platform for all types of electrical equipment, the working environment is harsh, wet working environment on the insulation capacity of equipment has caused a great impact, experience feng shui sun, equipment prone to leakage phenomenon. Due to the special nature of the offshore platform, in the event of equipment leakage problems, the resulting loss is incalculable, so pay special attention to equipment installation and maintenance. This paper simply analyzes the leakage protection measures of the offshore equipment for the electrical equipments, studies the leakage protection measures of the common neutral ungrounded system, and discusses the application of the leakage protector on the offshore oil platform.
