Electrical surge arrestor having fail-safe properties |
| abstract |
An electrical surge arrestor having fail-safe properties and providing breakdown at a predetermined region within a sealed structure. The arrestor comprises a pair of axially symmetric electrically and thermally conductive electrodes having integral terminal portions and discharge portions. The discharge portions are disposed coaxially in spaced confronting or nesting relationship within a coaxial ceramic insulative housing to provide a discharge gap at a selected area to form a sealed enclosure. The discharge gap is configured so that the discharge portions of the electrodes will fuse in response to the presence of a predetermined overload condition. The operating lifetime of the surge arrestor may be lengthened by shading an annular inner surface portion of the insulating housing from the discharge gap in order to minimize the deposite thereon of conductive material discharged from the electrodes during breakdown. The electrodes and insulating housing are formed of materials having substantially similar thermal expansion coefficients for providing a metal to ceramic seal resistant to thermal shock. |
