由图8、图9、图10所示，本发明的一种高压直流继电器相向电弧隔离装置，包括动触点组件和静触点组件，动触点组件包括动簧片1、固定在动簧片1左右两端的左动触点2和右动触点3，静触点组件包括与左动触点2相对应的左静触点4、与右动触点3相对应的右静触点5，左静触点4和右静触点5均与一个引出端6相固定，两个引出端6固定在绝缘板7上，绝缘板由陶瓷材料制成。
绝缘板7向下延伸有两个都具有能隔断两组动静触点之间的相向电弧的高度H的隔弧部件，隔弧部件呈板形结构，两个隔弧部件平行设置，一个隔弧部件相对位于推动杆9的左侧，另一个隔弧部件相对位于推动杆的右侧，且隔弧部件前后方向的尺寸L大于动静触点结合面的前后宽度M。隔弧部件与绝缘板7一体形成，且两个隔弧部件位于左静触点4与右静触点5之间。动簧片形成有通过孔15，推动杆的顶端从通过孔15延伸至动簧片上侧。
动簧片1的左动触点2和右动触点3之间形成有凹槽18，凹槽18前后贯穿动簧片1，当推动杆9带动动簧片1向上移动使左动触点2与左静触点4接触、使右动触点3与右静触点5接触时，两个隔弧部件8的下端均位于凹槽18内，推动杆的顶端位于两个隔弧部件8之间。
动簧片1包括与左动触点2相固定的第一部24、与右动触点3相固定的第二部25，与推动杆9相固定的第三部26，第三部位26于第一部24和第二部25之间，第一 部24的高度和第二部25的高度一致，且第三部26的最高处低于第一部24的最高处、低于第二部25的最高处，凹槽18即为第三部26上方的位置。
本发明用于高压直流继电器中，本发明具有可将相向的电弧隔离，避免相向电弧接触所造成的事故的发生的优点。
