Abstract
A metal ring adjacent the support insulator of a gas-insulated bus lines the interior of the outer grounded housing. The ring is formed to define at least a portion of a turn around the central bus so that, in the event of an arc from the central bus to the outer grounded housing, the arc root will fall on the interior of the metal ring and the arc current will create a magnetic field which will cause the arc root to rotate around the interior of the metal ring.
Claims11
A metal arcing ring for a high voltage gas-insulated bus;
- said bus comprising an elongated central conductor, an outer conductive gas-filled housing surrounding said central conductor and extending coextensively therewith, a support insulator secured to said central conductor and supporting said central conductor within said housing;
- said metal arcing ring comprising an electrically conductive member fixed to the interior of said housing and adjacent said support insulator and having an arc receptive surface facing said central conductor;
- said electrically conductive member defining at least a portion of a current carrying turn around said central conductor for producing a magnetic field which has at least a component thereof in an axial direction to the axis of said housing;
- one end of said conductive member being electrically connected to said housing;
- the remainder of said member being electrically insulated from said housing.
