潜水员水下用电安全的基本问题

ON DIVER S SAFE USE OF ELECTRICITY UNDERWATER

水下用电安全是潜水员在施工作业中经常遇到的一个实际、且辣手的问题.本文概要分析了潜水员水下用电安全的技大范畴、遭受电击时的主要特征、水下电气设备的故障漏电电流、防电击的基本方法、水中作业的安全距离,以及水中含盐量对用电安全的影响等与潜水员水下用电安全密切相关的若干基本问题.最后,笔者初步探讨了我国潜水员水下用电安全的标准规范体系,以及有关标准、法规制定的可行性与必要性.水下用电安全是潜水员在施工作业中经常遇到的一个实际、且辣手的问题.本文概要分析了潜水员水下用电安全的技大范畴、遭受电击时的主要特征、水下电气设备的故障漏电电流、防电击的基本方法、水中作业的安全距离,以及水中含盐量对用电安全的影响等与潜水员水下用电安全密切相关的若干基本问题.最后,笔者初步探讨了我国潜水员水下用电安全的标准规范体系,以及有关标准、法规制定的可行性与必要性.

The diver's safe use of electricity is a practical yet complicated problem in diving operation. In this paper several basic categories closely linked to diver's safe use of electricity underwater are probed, including the technical category of diver 's safe use of electricity underwater, the basic characteristics both physiological and electrical when incurring an electrical shock , the fault current of electrical equipments and installations underwater, the major methods of shock protection, the safe distance of operations underwater , and the effect of salt content of the water on electricity safty. Chinese standard and code system for diver's safe use of electricity underwater are briefly described,and their feasibility and necessity are discussed.
