摘　　要：变压器的电压比和联接组别试验,是变压器试验当中最基础的试验项目,它主要是验证变压器是否能够达到预期的电压变换效果。该试验贯穿于变压器的半成品试验、成品试验、现场验收试验、大修后的交接试验、变压器发生故障后的检查等试验过程,决定着变压器是否能够安全正常运行。笔者主要分析了各个过程中的电压比和联接组别试验,并根据工作经验进行了总结。The test for voltage ratio and check of phase displacement of the transformers is the most basic test item in the transformer test,which mainly verifies whether the transformer can achieve the expected voltage conversion effect.This test runs through the transformer^semi-finished product test,finished product test,site acceptance test,handover test after overhaul,inspection after transformer failure and other test processes,which determines whether the transformer can operate safely and normally.The author mainly analyzes the voltage ratio and connection group test in each process,and summarizes the work experience.
