  1. Igbt power modules, 25khz inverterfrequency, fast response time, high arc stability, almost spatter - free welding

    採用igbt模塊，逆變頻率達25khz ，動態響應速度快，穩弧性能好，焊接飛濺極小。
  2. Transitional feature of the arc and metal droplet in the welding process with steam shielded arc is investigated by means of analysing the waveforms of welding voltage and current under different welding regimes and it is found that there are two types of arc process behavor ? " arc starting - arc blowing out - short - circuiting " and " arc - starting - short - circuiting ". under the condition of constant diameter of welding wire and its feeding speed, the arc process behavor can be changed by adjusting the inductance of welding circuit as well as the voltage of power supply. if arc process behaves as alternative process of " arc starting - arc blowing out - short - circuiting " with minimum time duration of arc blowing out and maximum frequency of short - circuit transition, the welding process will be stable with less spatter and smooth weld bead

    通過分析不同焊接規范下的焊接電壓和電流的波形.研究了水蒸氣保護下電弧及熔滴過渡的特點，發現其電弧過程行為有「燃弧?熄弧?短路」和「燃弧?短路」兩種形式.在焊絲直徑和送絲速度一定的情況下，通過調節焊接迴路中的電感量和電源電壓，可以改變電弧的過程行為形式.若電弧過程呈「燃弧?熄弧?短路」交替進行，並且熄弧時間最短時，短路過渡頻率最高，在這種情況下，飛濺小，焊道成型好，焊接過程穩定
  3. By improving surface condition of parts and one shot seal - off clean room grade, using ultrasonic vapor phase cleaning process, the inner parts of vacuum interrupter get cleaner. movable particles have been diminished by automatic current ageing, power frequency hi - voltage ageing and dynamic high current ageing. as the dielectric strength of clearance in vacuum interrupter improved, the probability of re - ignition in test drops evidently

    通過提高零件表面加工質量，改善一次封排間的真空衛生條件、制定合理的超聲波氣相清洗工藝提高管內潔凈度，採用自動電流老煉、超高壓工頻老煉、大電流動態老煉等工藝進一步消除真空滅弧室內活動性微粒，可提高真空滅弧室真空間隙介質強度，使真空開關投切電容器組的重燃率大大降低，並通過實驗驗證真空開關投切電容器組的重燃率在製造工藝改進後由原來的10 . 7 %降低至1 . 3 % 。
  4. 3. 5in. 2 : information processing systems - data interchange on 90 mm 3, 5 in flexible disk cartridges using modified frequency modulation recording at 15916 ftprad, on 80 tracks on each side - track format

    信息處理系統.每面80磁軌改進調頻方式以15916次磁通變換弧度記錄速率徑向為90mm
