宇宙发电站采用的管子与卫星通讯发射机用的大功率管相比,对宽频带与线性没有高的要求,因此,通讯感兴趣的宽频带行波管在发电站内很可能不予采用。因为行波管效率低,故需要有结构相当复杂的降压集电极。在各种类型的速调管中,静电聚焦管的优点是重量轻,然而,这种管子必须改进,以达到磁聚焦管所具有的效率。对这种特殊用途的各种管子,在优值方面作比较性的讨论。表明:为了减轻管子的总重量,重要的是要使集电极在尽可能高的温度下工作。因为速调管中,热耗散电极是与电子枪及微波结构良好地隔离的,所以允许提高集电极的工作温度。为了在宇宙发电站设备中使用,把热辐射器的高温工作与以开放结构为基础的新工艺以及与导热管广泛应用相结合,使速调管处于十分强的竞争地位。
Compared with the high-power tubes used in satellite communication transmitters, the cosmic power generation substations do not have high requirements for broadband and linearity. Therefore, broadband TWTs that are of interest to communications may not be used in power stations. Because of the low efficiency of traveling wave tube, it requires a rather complicated structure of the step-down collector. In all types of klystrons, electrostatic focusing tube has the advantage of light weight, however, this tube must be improved in order to achieve the efficiency of the magnetic focusing tube. For this special purpose of various tubes, in terms of merit for comparative discussion. Show: In order to reduce the total weight of the tube, it is important to make the collector at the highest possible temperature work. Because the klystron tube, the heat-dissipating electrode is well isolated from the electron gun and the microwave structure, it allows to increase the operating temperature of the collector. In order to be used in cosmic power station equipment, the combination of high-temperature operation of heat radiators with new processes based on open structures and the widespread use of heat pipes has placed klystrons in a very competitive position.
