<p>An outdoor low-voltage fuse disconnector comprises terminals (11,12), a fuse body (2), stationary contacts (31, 32), an operating handle (6), insulators(19, 29), and a bottom plate (10). The fuse body (2) is mounted in a fuse body carrier(4).The bottom plate(10) is fixed with the left terminal (11), a rotation bracket (13) and the left stationary contact(31) via the left insulator (19), and the bottom plate (10) is fixed with the right terminal (12) and the right stationary contact (32) via the right insulator (29). The fuse body (2) is a contact fuse body, a metal grid arc extinguishing chamber (5) is provided below the right stationary contact (32), and a closing holding mechanism (8) is provided to hold the operating handle (6) in a closing position. When the fuse body carrier (4) is pulled down, the fuse body (2) will be pulled out along as a moving contact of the disconnector, forming an observable visible air isolation gap at the supply side and the load side. The disconnector is low in temperature rise and long in service life, strong in short-circuit current limiting capacity and breaking capacity high in reliability, easy to match, safe in isolation, convenient to operate and maintain, safe and reliable in outdoor operation and economical and effective.</p> |
