711测雨雷达显示器电源部系采用电子管进行比较放大、调整等。由于+300V—组输出耗电达710mA,虽然调整管用11只693P并联使用,但6P3P电子管仍接近于极限工作状态(每只72mA)。因此,6P3P管损耗较多。同时从多年工作实践统计表明,显示器电源部(包括±150V)故
711 Rain Radar Monitor Power Department Department of the use of tubes to compare amplification, adjustment and so on. As the +300 V-group consumes up to 710 mA, the 6P3P tube is still close to its limit operating state (72 mA each), although 11 693P regulators are used in parallel. Therefore, 6P3P tube loss more. At the same time from many years of work statistics show that the display power section (including ± 150V) so
