昆明特高压交直流人工污秽实验室设计和功能

Design and Function of the UHV DC and AC Artificial Pollution Laboratory in Kunming

特高压交直流人工污秽实验室是特高压工程技术(昆明)国家工程实验室的一个组成部分,用于研究高海拔条件下外绝缘设备的染污放电特性,为特高压交直流输电工程外绝缘设备的选型和外绝缘的设计提供技术支撑。鉴此,介绍了该实验室的建设方案、设计思想和技术特点。基于该实验室的设备功能,可进行三类试验研究:校核验证性试验;工程前期试验;科学研究性试验。该实验室将在其2 100 m海拔高度开展对悬式、支柱绝缘子、穿墙套管及避雷器等外绝缘设备的染污放电特性系统研究。

The UHV DC and AC artificial pollution laboratory,a part of National Engineering Laboratory for UHV Engineering Technology in Kunming,is for the purpose to research the discharging characteristics of insulation equipments under pollution at hight altitude in order to provide technical support of insulator selection and insulation design for UHV DC and AC projects.This paper presents the construction scheme,the design conception and the technical characteristics of the laboratory.Based on the equipment functions,three types of test can be carried out in the laboratory,i.e.verification test,preliminary test and research test for UHV DC and AC transmission projects.A series of systematic research are planned for the laboratory,such as pollution performance for suspension insulator,post insulator,wall bushing and arrester at 2 100 m of the altitude.
