摘要

文中基于电网防雷技术全球专利

运用检索、计量、统计、对比等分析方法

从专利申请量、主要申请机构、技术分布、核心专利、保护区域等方面分析全球电网防雷技术的竞争态势以及中国电网防雷技术在全球的竞争力。结果表明

中国电网防雷技术总体上处全球领先地位

竞争优势明显

具体表现在:中国专利申请量稳居全球首位

尤其是近五年专利数量占全球专利总量的90%以上;中国国家电网公司是全球最主要的专利申请机构

其不仅专利申请量远超中国南方电网公司、日本碍子公司、日立电缆有限公司等国内外竞争对手

而且其专利的技术分布广泛

并拥有大量的核心专利技术。值得注意的是

和日本相比

中国机构在专利的国际布局方面不占优势

需增强技术的全球保护意识

加快制定和实施专利全球发展战略。

Abstract

The competition situation of lightning protection technologies for power grid in the world and the competitiveness of China in this field are analyzed in terms of patent application number

main application institutions

technology layout

core patents

and protection region based on the global power grid lightning protection technology patents. The methods of retrieval

metrology

comparison

and statistics are employed. The results show that the Chinese lightning protection technologies for power grid possess the leading position in general in the world and have obvious advantage

including that: 1)the application amount of Chinese patents ranks first in the world

and especially for the global recent five-year patent applications

Chinese patent applications account for more than 90%;2)State Grid Corporation of China is the leading patent holder in the world

whose patents are far more than that of NGK Insulators

Hitachi Cable

China Southern Power Grid or other competitors

and it owns a large number of core patents and broader technical layout and field coverage. However

it is worth noting that compared with Japanese institutions

Chinese institutions do not have the advantage in international layout of patents

so they need to enhance the awareness of global protection of technology and accelerate the formulation and implementation of global patent development strategies.
