氣體分析動態(tài)體積法制備校準用混合氣體

內(nèi)容簡介

本書系統(tǒng)地總結(jié)了作者十多年來在SF6與其混合氣體中電弧動態(tài)特性

的研究成果。書中第1至5章，全面敘述SF6與其混合氣體的基本特性和有

關(guān)實驗研究。第6至9章著重介紹創(chuàng)新建立的電弧二維動態(tài)數(shù)學(xué)模型和所采

用的數(shù)值分析方法及其應(yīng)用。第10至14章，深入分析SF6與其混合氣體中

電弧熱邊界區(qū)特性和電弧阻塞現(xiàn)象，并系統(tǒng)地研究其氣流特性。最后兩章敘

述滅弧室結(jié)構(gòu)參數(shù)的綜合調(diào)整，以改善混合氣體滅弧室的開斷特性，為在斷

路器中應(yīng)用SF6/N2混合氣體取代純SF6提供了科學(xué)依據(jù)。

本書不僅對分析SF6和SF6/N2混合氣體電弧特性有理論意義，并且對

SF6和SF6/N2混合氣體斷路器的研制開發(fā)具有實用價值。

本書可供高等學(xué)校、研究和設(shè)計制造單位有關(guān)專業(yè)的教師、研究生、科學(xué)

研究人員和工程技術(shù)人員參考應(yīng)用。

A BRIEF INTRODUCTION TO THE BOOK

The systematical results of the authors' researches on dynamic charac-

teristics of electric arcs in SF6 and its gas mixtures are summed up in this

book. From Ist to 5th chapters, the fundamental properties of SF6 and its

gas mixtures and experimental researches concerned are comprehensively re-

lated. From 6th to 9th chapters, a new two-dimensional mathematical model

of arc and its numerical analyses and applications are presented. From lOth

to 14th chapters, characterictics of thermal bounday region of arc and phe-

nomena of arc clogging in SF6 and its gas mixtures are analyzed. In the last

two chapters the comprehensive adjustments of construction parameters of

the interrupter are introduced in order to improve the breaking characteris-

tics of the interrupter with SF6/N2 gas mixtures.

This book is an academic monograph and applies to teachers, postgrad-

uates, researches and engineers of relevant specialities of universities, re-

search and design institutes.
