为了大功率雷达发展的需要,目前已研制出一种大功率陶瓷充氢闸流管。该管能承受35千伏的正向阳极电压,脉冲电流可达1000安培以上,平均电流为4安培,系我国目前功率最大的充氢闸流管之一。该管采用陶瓷金属结构,陶瓷与金属的连接采用钛-银-铜活性封接法密封,而整管各部件则通过三道氩弧焊组合而成。管子最大部分直径约150毫米,高约380毫米。阳极采用不渗透氢气的无氧铜皮作成杯形,并构成管壳的一部分,从而大大增加了阳
In order to develop the high-power radar needs, has developed a high-power ceramic thyristor valve. The tube can withstand 35 kV forward anode voltage, pulse current up to 1000 amps, the average current of 4 amps, Department of China’s current power is the largest charge of the thyristor. The tube adopts the ceramic metal structure, the connection between the ceramic and the metal is sealed by the titanium-silver-copper active sealing method, and the whole pipe is formed by the combination of three argon arc welding. The largest part of the tube has a diameter of about 150 mm and a height of about 380 mm. The anodes are made of cupped oxygen-impermeable copper skin and form part of the envelope, greatly increasing the positive
