摘要

电力接地是保障电力设施安全的关键环节。然而,在电力设施运行过程中,接地材料的腐蚀会引起事故。因此,监测接地材料的腐蚀状况,可以消除接地网中的安全隐患,保证电力的安全运行。本文采用电磁超声测厚技术,在现役电力接地材料上安装电磁超声测量探头,开发了接地材料腐蚀在线监测系统。变电站接地网实例表明,与其他监测方法相比,在线腐蚀监测系统可以获得更精确的接地腐蚀数据,具有更广泛的应用前景。

Investigation of Online Corrosion Monitoring for Grounding Materials Based on Electromagnetic Ultrasonic Technology
Power grounding is a key aspectofensuringsafety in power facilities.However, the corrosion of grounding materials can cause accidentsduringpower facility operation. Therefore, monitoring the corrosion status of grounding materials can eliminate hidden risks in the grounding network and ensure safe poweroperation. In this paper, electromagnetic ultrasonic thickness measurement technology was used to develop an online corrosion monitoring system for grounding materials via the installation of electromagnetic ultrasonic measurement probes on in-service power grounding materials. The results from a substation grounding networkdemonstrate that the online corrosion monitoring system can obtain more precise grounding corrosion data and has more extensive application prospects compared with other monitoring methods.
