简介：摘要变压装置在电力体系中的应用较为广泛，从发电，送电，配电和用电的各个板块均需要变压器，但当前变压器负荷率不高，对经济运行产生很大负面影响。本文首先给出提升变压器负荷率的重要措施，包括选择变压器容量，提高变压器利用率，科学调节用电负荷，进而分析了现场调节方法，即调整停运空载与轻载变压器，调节母子变供电模式。给出无功补偿，如调节反馈控制和负荷率，完成电量解析与负荷测算，分割变压器经济运行区间。

简介：摘要本文首先介绍了特高压变压器的结构以及调压方式，其次介绍了特高压变压器几种差动保护配置方案分相差动保护、稳态比例差动保护、分侧差动保护、零序差动保护。最后介绍了调压补偿变压器的原理，以供参考。
