高压工频电场警示仪的研究

Research of High-voltage Power Frequency Electric Field Warning Instrument

环评测试表明,在高压线路下和变电站内部分区域,电场强度超过国家标准5kV/m规定的最大值。为了便于电力工作人员及时准确的获得作业场所的电场信息,本文以C8051F020单片机为核心开发研制了高压工频电场警示装置。现场测试表明,该装置不仅可以对电场强度进行测量,当环境的电场强度超过规定值时,其声光报警系统可以自动告警,能满足电力系统对电场环境监测的需要。

Environment impact tests both under the high-voltage transmission lines and in the high-voltage substations indicate that the electric field strength in some places exceeds 5kV/m which is the allowable value of national standard. In order to help power workers to get the electric field information around the working place accurately and immediately, a power frequency electric field warning instrument is designed based on C8051F020 single-chip. Experiments have shown that the instrument can not only measure the power frequency electric field, but also warn automatically when the electric field strength in the environment is larger than the standard authorized value. It can meet the demand to monitor the electric field environment in power system.
