摘　　要：针对目前交流工频耐压试验装备存在补偿电抗器容量不可调的不足,研制出200 kV,100 kV·A磁控谐振试验变压器。该试验系统集升压、被试品电容平滑无级补偿于一体,结构紧凑、精准补偿。本文给出了该系统的结构组成与基本原理,建立了仿真模型,研究了200 kV磁控谐振试验系统运行特性,并验证了该试验系统的升压和自动调谐能力。当被试品电容范围小于16 000 pF时有较好的调谐效果。通过200 kV样机试验,验证了该试验系统的可行性。In view of the unadjustable capacity of compensation reactor in the current AC power frequency withstand voltage test equipment,a 200 kV,100 kV·A magnetically controlled resonance test transformer is developed.The test system integrates step-up,smooth and stepless compensation of the tested object capacitance,with compact structure and precise compensation.This paper presents the structure and basic principle of the system,establishes a simulation model,studies the operation characteristics of the 200 kV magnetic resonance test system,and verifies the boosting and automatic tuning ability of the test system.When the capacitance range of the test object is less than 16000 pF,it has a better tuning effect.Through 200 kV prototype test,the feasibility of the test system is verified.
