变压器有载调压分接开关动作特性交流测试技术的研究与应用

Research and Application of AC Testing Technology for Operating Characteristics of On- load Tap- changer of Transformer

针对变压器有载分接开关动作特性测试,提出了一种新的测试方法。模拟变压器的运行状态,对变压器有载分接开关动作特性作采用交流测试技术,从根本上解决了现场分接开关切换过程的动作特性不能准确判定、多种接线组别变压器分接开关动作特性不能测试等问题。

Aiming at the operating characteristic testing of on -load tap-changer of transformer , a new testing method is pro-posed .The operation condition of transformer is simulated , and AC testing technology is adopted for the operating characteris-tics of on-load tap-changer .A thoroughly solution is provided for some problems , for instance , the operating characteristics of tap-changer during switching in site cannot be determined accurately and the operating characteristics of tap -changer of transformer in several wire connection groups cannot be tested .
