电网绝缘子等值附盐密度智能测试仪的研制

The research and development work of an instrument designed for measuring the eguivalent salt deposit density of the high-voltage insulators

介绍了电网绝缘子等值附盐密度智能测试仪的研制 ,详细阐明了有关工作原理和设计关键。测试仪以AT89系列单片机 89C52作为核心器件 ,利用其运算功能直接测量出绝缘子清洗液的等值附盐密度。对决定电网绝缘子的清扫周期 ,有效防止电网大面积污秽闪络事故的发生有明显的作用。

The development and research work of an intelligent instrument for measuring the equivalent salt deposit density of the insulators is described in this paper.The relevant work principal and key problems for the design is also discussed in details.The 89C52 of the AT89 microcomputer are used as the core device to measure the equivalent salt deposit density of the clenser for cleanly the insulators.It is evident that the instrument can be applied to determine the time period for cleaning the insulators and to prevent the power network from the accident caused by dirt sparks in a large area.
