Rotating arc interrupter for loadbreak switch.

摘要

A loadbreak switch (10) is provided that utilizes a pivotally mounted movable jaw contact (14) and a main stationary contact (16) that is positioned in the middle of an arc runner (40). For operation at voltages 15kV and above, the switch (10) utilizes a shunt contact (42) that bridges the arc runner (40) and that is above and coplanar with the main stationary contact (16). A magnetic field is developed by the current that flows through a coil of wire (44) disposed around the arc runner (40). This configuration when utilized in an environment of insulating gas, provides efficient extinguishing of arcs upon opening of the contacts. Further, the open jaw contact is easily visible to establish an open gap. <IMAGE>
