高分断能力真空灭弧室的研制

Investigation of Vacuum Interrupter With High Interrupting Capacity

研究了一种新型高分断能力的真空灭弧室，其间隙纵向磁场较强且具有良好的分布特性。试验表明，该真空灭弧室具有较强的分断能力，并有利于真空灭弧室的小型化。

Study on a new type of high interrupting capacity vacuum interrupter is given, a twopole axial magnetic field electrode with horse iron is introducted. The result of calculating the magnetic field shows that its axial magnetic field distributs intensely and evenly between the contacts. Through test, it is proved that the vacuum interrupter based on this method has higher interrupting capacity and compactness.
