The paper applies sdm in analysis of the cause of pollution flashover , brings up the patrol and investigate attention , as a reference of planning power line patrol and investigate scheme 同时在分析了污闪事故发生的各种条件基础上,应用空间数据挖掘,提出了线路关注度这一新的指标,作为绝缘子状态巡检计划编制的参考指标。
On the condition of insulator covered in snow or ice chill climate area of northeast in china , many accidence of insulation flashover occurred which brought prodigious damage for electric power system and loss for economic 国内东北地区在寒冷气候条件下覆冰覆雪时曾发生过多次闪络和绝缘击穿事故,造成极大危害和经济损失。
Flashover is preceded by dry - band arcing and extension of the arc to bridge the insulator . this combination significantly modifies both the magnitude and shape of the leakage current 本文在检索大量国内外参考文献及研究成果的基础上,提出一种性能价格比优良的线路绝缘子在线监测方案? ?基于msp430的输电线绝缘子泄漏电流检测。
With the development of electric power system arid the aggravation of pollution , contamination flashover in hv insulator is getting worse and worse , so there ' s great importance in the measuring of hv insulator ' s leakage current 摘要随著电力系统的发展和各类污染的加剧,高压绝缘子的污秽闪络事故日益严重,对其泄漏电流的检测具有实际工程意义。
This article , which researches on composite insulators " ac flashover characteristic in high altitude and ice environment , has significant science values in theory and can also create enormous economy benefit in engineering 因此本文研究合成绝缘子在高海拔和覆冰地区的交流闪络特性在理论上具有非常重要学术价值,在工程上能够创造巨大的经济效益。
It has also been found that the pre - flashover events and the charging characteristic are related to the flashover performance , the samples with seldom pre - flashover events and lower charging ability show a better flashover performance 通过研究发现,对于同组分的陶瓷材料来说,如果材料的晶粒越小,分布越均匀,缺陷越少,则该材料的沿面闪络电压就越高。
an unintended electric discharge (as over or around an insulator)
百科解释
A flashover is the near-simultaneous ignition of most of the directly exposed combustible material in an enclosed area. When certain organic materials are heated they undergo thermal decomposition and release flammable gases.
