摘要
介绍了电缆参数及其测量方法,总结了国内煤矿检验机构对本安设备用电缆的防爆检测方法,通过实例理论分析了采用系统认证时所存在的问题,归纳了IECEx普遍采用的参量认证检测方法,为解决长距离供电时的防爆问题提出了提高电缆允许长度的方案。
This paper introduces the cable parameters and measurement methods, and summarizes test methods of the cable used by intrinsically safety electrical apparatus in domestic coal mine inspection organizations. The paper analyzes the problems in the application of system authentication in theory through a practical example, and summarizes the method of parameter authentication commonly used in IECEx. In order to solve explosion protection of the cable for long distance power supply, the paper proposes the schemes to improve the allowable length of the cable.
