摘　　要：根据GFE(L)1型测风雷达原理及电路图,结合雷达分机结构,综合整编出了全机电源供给概况和供电流程详解图,内容集实用性、综合性、资料性于一体。文章阐述了全机电源的产生、变换过程,各分机之间电压传输路径和方向以及供给各分机、功能板(盒)、器件等的电压种类及正常数据,为L波段测风雷达的故障判断和维修提供了依据。实践证明:根据供电流程进行故障分析、判断和检修,大多数雷达故障均可解决,可收到事半功倍的效果。According to principles and circuits of GFE（L）1wind radar, and combined with the extension structure of radar, this paper gives an overview of the whole machine power supply and presents detail drawings of flow path, which have characteristics of the practicality, comprehensiveness and reference. It also points out generation and transformation process of the whole machine power, illustrates transmission path and direction of the voltage between extension nodes, and shows types and normal data of voltage supplying for extension, functional board （box） and devices etc, which provide a basis for judging and maintaining failures of L-band wind radar. The practice proves that most of the radar failures would be easily dealed with and have a multiplier effect based on failure analysis, judgment and maintenance for power supply flow.
