避雷器检测专利技术综述

Overview of Patent Technology for Lightning Arrester Detection

避雷器是目前电网最重要的过电压保护装置,其可靠性很大程度上取决于设备绝缘性能的好坏,一旦其出现故障,未能保护过电压的侵害,将会对整个电网造成巨大的损失。因此避雷器的检测对电力系统安全可靠运行至关重要。文章基于CNABS和DWPI数据库,通过检索、筛选、统计和分析国内外与避雷器检测相关的发明和实用新型专利,专利数据选取的时限为2018年5月1日之前公开的专利申请,共选取1589项专利文献为专利分析样本,对该领域专利申请量、技术原创国与目标国、申请人等做了统计分析,为行业发展和审查工作提供参考。

Lightning arrester is the most important grid voltage protection device,with its reliability basically depending on its insulation performance.Once it fails to function properly,it can damage the whole grid as it fails to protect from voltage damage.Therefore,the reliability of lightning arrester is profoundly important to the security of the Grid.This paper is based on CNABS and DWPI database,searching,filtering,collecting and analyzing data so as totest the related inventions and utility model patents.The collected data was based on the invention applications till 1stMay 2018,and a total of 1589 patent documents are selected as patent analysis samples,and the number of patent applications in this field,the original and target countries of technology,and applicants are statistically analyzed in order to provide reference for the development and examination of the industry.
