Electrical switching apparatus having arc runner integral with stationary arcing contact |
摘要 |
An integral stationary arcing contact and arc runner for electrical switching apparatus is formed by an electrically conductive member secured to the line conductor adjacent the stationary main contact thereby providing a joint free path for the arc to pass from the arcing contact to the arc runner. Preferably, the electrically conductive member is a sheet metal member having a base section secured to the line conductor, an arcing contact section adjacent the stationary main contact and extending generally perpendicular to the line conductor and a runner section extending at an obtuse angle to the arcing contact section toward the arc chute. A support member between the arcing contact section and the housing transmits reaction forces imposed by the moving conductor assembly on the sheet metal member into the housing.
