昆明高海拔特高压户外试验场的技术特点和研究项目

摘要

The Kunming UHV outdoor test field at high altitude is a key part of the National Engineering Laboratory（Kunming） for UHV Engineering.Configured with a portal tower of 70 m×70 m and deadend towers,the test field is available for UHV transmission and transformation equipments,air gap and conductors of large scale.With the advanced test equipments,including a 2 250 kV AC test transformer,a 7 200 kV impulse generator,a ±1 600 kV DC voltage generator and a excellent grounding system,the insulation experimental research of 1 000 kV AC and ±800 kV DC power systems can be carried out in the test field.According to the purpose of test,three types of test research could be done,namely the verified tests,the preparatory tests for engineering and the tests of scientific research.%昆明高海拔特高压户外试验场是特高压工程技术（昆明）国家工程实验室的重要组成部分。该户外试验场装备有净空70 m×70 m的门形架一座和锚塔一组,可方便布置大尺寸的特高压输变电设备、空气间隙和悬挂长真型导线等试品。户外试验场具有目前先进水平的2 250 kV工频试验变压器、7 200 kV冲击电压发生器和±1 600 kV直流电压发生器,以及良好的接地系统,可供交流1 000 kV、直流±800 kV输变电设备及系统进行绝缘试验研究。按照试验目的,户外特高压试验场的试验研究分为三类：校核验证性试验、工程前期研究性试验和科学研究试验。
