聚焦线圈是向雷达发射机中大功率速调管提供直流磁场的重要装置。线圈的制作水平直接影响速调管的效率。聚焦线圈尺寸大,误差要求高,因此线圈绕制过程中不仅要有科学的排线方法,而且需要可靠的绕制夹具。文中介绍了排、叠绕方法及绕制夹具的设计。聚焦线圈要求在200℃温度下长期、稳定地工作。为此文中介绍了能满足技术要求 Focusing coils are important devices that provide a DC magnetic field to a high-power klystron in a radar transmitter. The level of coil production directly affects the efficiency of the klystron. Focus coil size, high error requirements, so the coil winding process not only have a scientific cable method, and the need for reliable winding fixture. This article describes the row, winding method and winding fixture design. Focusing coils require long-term, stable operation at a temperature of 200 ° C. This article describes the technical requirements to meet
