参考图3，动侧灭弧装置200包括导流杆201、合闸动弧触杆210、分闸动弧触杆220和动侧分闸限位部，合闸动弧触杆210、分闸动弧触杆220皆采用铜钨材料制成，还包括第三回弹装置，导流杆201上设置有两个互相间隔一定距离的安装抱箍202，动触头300固定在安装抱箍202上且与导流杆201平行。合闸动弧触杆210通过两个螺栓固定在导流杆201的末端并且与导流杆201垂直。分闸动弧触杆220通过一转动装置安装在导流杆201上，转动装置包括动弧触头转块240、动弧触头摆杆230、动弧触头转轴，动弧触头转块240通过动弧触头转轴可转动安装在导流杆201上，动弧触头摆杆230的顶端与分闸动弧触杆220的底端固定连接，动弧触头摆杆230的末端固定在动弧触头转块240上。

本发明实施例中开合高参数的母线转换电流装置的分合闸过程为：
参考图4-图5，合闸过程为：动触头300沿箭头方向往合闸方向运动，合闸动弧触杆210碰到合闸静弧触杆110，合闸静弧触杆110在左第一左扭簧111和第一右扭簧112的力矩作用下与合闸动弧触杆210保持一个稳定可靠的接触力，电流通过导流杆201、安装抱箍202传导到动触头300的回路上，继续合闸过程中分闸动弧触杆220碰分闸静弧触杆120后，由于分闸静弧触杆120被缓冲弹簧柱130限制不能往后退，而分闸动弧触杆220则可以往后转动，因此在分闸动弧触杆220碰触分闸静弧触杆120后，分闸动弧触杆220开始往后摆动并绕过分闸静弧触杆120；然后分闸动弧触杆220在复位扭簧250的作用下复位，此时分闸动弧触杆220绕到分闸静弧触杆120的后方。直到动触头完成合闸，合闸动弧触杆210与合闸静弧触杆110的接触压力一直持续保持。
参考图6-图7，分闸过程为：动触头300沿箭头方向往分闸方向运动，首先动触头300与静触头400脱离分开，而合闸静弧触杆110在第一左扭簧111和第一右扭簧112的作用下会与合闸动弧触杆210一起往分闸运动，动触头300与静触头400脱离分开后合闸动弧触杆210与合闸静弧触杆110仍然保持稳定接触，继续分闸后，分闸动弧触杆220碰到分闸静弧触杆120后，将分闸静弧触杆120钩住并往外拉，而分闸静弧触杆120在左右复位扭簧的作用下与分闸动弧触杆220保持一个稳定可靠的接触压力，此时合闸动弧触杆210与合闸静弧触杆110，分闸动弧触杆220与分闸静弧触杆120都是导电连接状态，继续分闸后，合闸 静弧触杆110碰到限位板140而停止向前运动，而合闸动弧触杆210继续运动后与合闸静弧触杆110脱离，而此时分闸动弧触杆220与分闸静弧触杆120仍然保持稳定接触，继续分闸后，当分闸动弧触杆220钩住分闸静弧触杆120滑动到静弧触杆顶端后开始脱离，脱离后，分闸静弧触杆120在左右复位扭簧的扭矩作用下快速回弹至缓冲弹簧柱130上，达到了快速分闸灭弧的效果。
综上，本发明实施例的开合高参数的母线转换电流装置不仅大大提高了弧触头的分闸速度，能够快速切断高参数母转电流产生的电弧。而且达到了真空断路器的灭弧效果，但结构简单、成本低，安装方便。
上面结合附图对本发明实施例作了详细说明，但是本发明不限于上述实施例，在技术领域普通技术人员所具备的知识范围内，还可以在不脱离本发明宗旨的前提下作出各种变化。
