放电管

• Vacuum switchgear tubes , gas spark gaps and pseudospark tubes are all switches of gas discharge theory , and have the good qualities of high withstanding voltage , high amplitude of current and high power
  真空开关管、火花开关、伪火花放电管都是利用气体放电理论的开关元件,具有高耐压能力、高峰值电流、功率大等优点。
• We use a isolating impedance between the gas diode and the silicon avalanche diodes , to permit the gas tube to operate properly and to permit the low energy avalanche diode to perform its voltage limiting function - without being damaged
  我们在气体二极管和硅雪崩二极管之间使用一个隔离阻抗，使气体放电管正常地运作，同时又使低能量的雪崩二极管发挥其电压限制功能，而不遭受损害。
• Explaining their distinguished features in lighting , the department s regulatory services controller , mr roger lai , said the registered buildings had put in place energy efficient fluorescent lamps and discharge lamps , and lamp fittings with reflectors and louvre
  机电工程署规管服务总监黎仕海在解释注册建筑物的照明特点时表示，它们均安装了具能源效益的萤光灯放电管灯，以及设有反光板和灯罩的灯具。
• Our company is ready to design and manufacture all kinds of discharge tubes and switching spark gaps of different outline dimensions , different current grades , different performance index and operation requirements , different specifications and models for new and old customers
  我公司愿意为新老客户设计制造不同外型尺寸不同电流等级不同性能指标及使用要求不同规格型号的各种类型放电管及开关放电器。
• For example , when using pid control method of controlling the electrical current of the discharge , with the discharge tube exposed to the outside with very good thermal dispersion conditions , unrestrained thermal expansion back - pack style he - ne laser tube gave good results
  采用控制激光器的放电电流的pid控制模式，在放电管外露，散热条件好；热变形不受约束的背包式he - ne激光管上取得了很好的效果。
• However , unsatisfactory results were obtained under the following conditions : discharge tube covered with glass cover , thermal dispersion conditions not as effective , thermal expansion of the discharge tube restricted by the co - axis glass cover ( longer preheat time , lower anti - interference )
  在放电管外有玻璃罩，散热条件差；放电管温度变形受外玻璃罩约束的同轴式管子上则效果不理想(预热时间较长，抗干扰能力不如前者) 。
• Gas discharge tube s varieties and standards are very complete . it is characteristic of feature b current resistance , small capacitance , rapid response , discharge voltage stabilization , and has no light sensation effect and does not contain any radioactive material . it is optimal lightning strike over - voltage protection devices
  其中陶瓷气体放电管品种规格全，产品耐流强，电容小，响应时间快，放电电压稳定无光敏效应，及不含任何放射性物质。
• The gas discharge exchanger and transistor used in main distributing frames of program control exchangers can meet the quality verification requirements for network access of ydt694 - 2004 main distributing frames and the technical requirements for lightning proof ensure public security of ga173 - 2002 computer information system
  程控交换机总配线架用的气体放电管和半导体管满足yd t694 - 2004总配线架进网质量认证要求，和ga173 - 2002计算机信息系统防雷保安器技术要求。
