Arc extinguishing installation for a circuit breaker with a double break |
摘要 |
<p>A magnetic casing (91) fits around a pre-chamber so as to amplify magnetic blowing action on an electric arc formed between the pre-chamber's first (51) and second (61) electric arc running rails. Inserted into an arc-quenching circuit, a blowing loop runs parallel to an electric arc running rail in sections. An independent claim is also included for a safety switch with a two-way interrupter switch.</p> |
