精品文档---下载后可任意编辑设计任务和程序首先满足国家有关标准规定的要求，还要同时符合设计要求，通常变压器设计要求包括如下技术法律规范。变压器形式：相数、绕组数、是否为自偶、升压或降压。变压器额定容量：对于三相变压器或自偶变压器，应说明个绕组的额定容量，或在不同的冷却方式下的容量。变压器冷却方式：油浸自冷、油浸风冷、强迫油循环风冷、强迫油循环水冷、强迫油导向循环风冷、强迫油导向循环水冷。当存在两种冷却方式是在不同冷却方式下的额定容量。变压器额定电压与调压方式：高压、中压或低压的额定电压，是有载调压或无励磁调压级其分接范围、分接级。若为有载调压时，应注明是中性点调压，还是线端调压。其他法律规范：变压器阻抗电压值；联结组标号；变压器附载损耗；空载损耗及空载电流；套管型电流互感器的技术数据；额定频率；安装地点海拔。特别要求：如防污要求；低噪声及运输要求等。关键词：电力变压器；电磁计算；冷却方式；结构改进精品文档---下载后可任意编辑AbstractDesign tasks and proceduresFirst meet the requirements of the relevant standards of the state, but also meet the design requirements, usually the transformer design requirements include the following technical specifications.1) the form of the transformer: the number of phase, the number of windings, whether for self - even, to boost or buck.2) the rated capacity of the transformer: for a three-phase transformer or a self even transformer, the rated capacity of the windings, or the capacity of the different cooling methods.3) cooling methods of transformers: oil immersed natural cooling, oil cooling, forced oil circulation air cooling, forced oil circulation cooling, forced directed oil circulation air cooling, forced directed oil circulation water cooling. When there are two types of cooling is the rated capacity in different ways.4) transformer rated voltage and the voltage regulation mode: high, medium or low rated voltage is on load voltage regulating or no excitation voltage regulating...
