  1. 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 % 。
  2. Surface, the easliy wear and tear parts use grinding - resistant material, extruding part use variable cylinder diamethe extruder with compact structuures, transmission gear with hard gear ter detachable pitch, great extruding p0ressure, high vacuum degree, low loading capacity ( electricity - saving more than 25 % than the same product ). it reaches advanced domestic level andcan replace imported items. it is suitable to produce hollow brick with high hole ratio, coal waste rock hollow bricks, shale hollow bricks, prower coal ash hollow - bricks. the extruder won the scienttific and technological progress pride of the lst building material scientific and techniques achievement exhibition in jiangsu province and the golden prize of the mational brick and tile energy - saving lxln achievement

    該機結構緊湊、傳動齒輪均系硬齒面，易損件採用耐磨材料、擠出部分採用變缸徑、變螺距、擠出壓力大、真空度高，裝機容量低（比同類產品節電25 % ） ，性能優于進口同類設備，適用生產高孔洞率空心砌塊、煤矸石、頁巖、精煤灰空心磚及各類高摻入量粉煤灰磚和低塑性原料磚，該機在江蘇省首屆建材科技成果展覽會科技進步獎； 94全國磚瓦節能四新成果展覽會金獎，西安國際博覽會金獎。
  3. The aim is to reduce the reignition rate and over - voltage damage from the perspective of the mechanical characteristics of the vacuum breaker switching shunt capacitor banks

    最終的目標是從真空斷路器機械特性方面入手，降低操作並聯電容器組時的重燃率、並減小操作過電壓危害。
