Design and manufacture of high-voltage disconnector test equipment for Harmony series high-power electric locomotives

Abstract

With the continuous improvement of the maintenance technology system of harmonious high-power electric locomotives, the quality requirements for the maintenance of important parts are getting higher and higher. Based on the traditional manual detection of the performance of the high-voltage disconnector, it can no longer meet the current status of advanced maintenance. According to the relevant requirements of the maintenance of parts and components in the Harmony Electric Locomotive Maintenance Regulations of the State Railway Group Co., Ltd., a design scheme of the main function test equipment for the high-voltage disconnector had been given, the technical application and verification indicators in the design scheme discussed, and the test equipment manufactured. Combined with the actual production conditions, the developed test equipment can meet the relevant indicators required by the regulations, and has been put into use in production.
