电工行业中的真空应用技术

Vacuum Application Technology in Electric Trade

近年来，随着改革开放的形势进一步深入，我国电工行业各厂（包括电力变压器、电力电容器、电力电缆、绝缘材料、高低压开关、互感器、电瓷、整流器、电机等）纷纷引进国外先进技术。其中有关制造工艺和专用设备很重要部分是真空应用技术，也就是“ＶＤ”、“ＶＰＩ”工艺及其设备。众所周知，电工产品质量的好坏。最根本的是反映于其绝缘性能如何，而大部分绝缘材料为了获得更高的绝缘强度，必须经过加工处理。这就导致了真空技术在电工行业中的应用、而且应用范围之广，涉及面之宽是其他行业所不及的．本文主要通过介绍电工行业的真空技术应用概况，呼吁我国真空技术界应将视野从传统的、单一的真空获得、测量检漏以及真空系统这种较狭义的真空技术概念转移到与真空有关的各种复杂而又面广量多（即中、低真空范围）的应用技术领域中来。

In the recent years, with the“reform and open” policy, the advanced technology abroad are gradually introduced by many factories of electric trade in our country (including power transformer, power capacitor, power cable, insulating material, switch for high and low voltage, mutual-inductor, electro-technical porcelain, rectifier, electric machine etc. Among them, most part of relative manufacturing engineering and special equipment belonged to the vacuum application technology, e. g “VD”,“VPI”process and its equipment. It is well known that the quality of electric product is good or is not principally dependent on its insulating property. To obtain the good insulationg strength, the most insulating material must be processed . This led to a result of the application of vacuum technology in electric trade. The application is wider and the related area is larger in this field than those in other trade. On the basis of the application of vacuum technology in electric trade.In this paper,the main aim is to hold interest of people in the vacuum technology circle in our country from the narrow vacuum technology of traditional, single vacuum production, measurement and leakage detecting, vacuum system to the application technology related with vacuum technology which is more complex in wide field (in the high, middle and low vacuum pressure).
