Description
Technical field
The present invention relates to and relate to high voltage protective electrical equipment, particularly relate to drop-type arrester.
Background technology
Drop-type arrester is arranged in the drop type mechanism of fuse switch after being reequiped by distribution type zinc oxide arrester, reach when not power-off, can detect lightning arrester easily, keep in repair and change by insulation joystick of operating a switch, not only ensure that the unimpeded of circuit, and greatly reduce working strength and the time of electric power maintenance personnel, the place being particularly suitable for having a power failure is as communication, airport, station, hospital, bustling business district etc., and other performances of product are with distribution type lightning arrester.
Drop-type arrester adds disconnector, when there is abnormal breaking down in lightning arrester, utilize power frequency short circuit current by disconnector action, disconnector earth terminal is thrown off automatically, unit of an arrester turns over, Accident prevention progress out of service expands, and is easy to attendant's Timeliness coverage and carries out safeguarding and changing.Drop-type arrester needs to possess quick action, and operating current scope is wide, and can tolerate again the feature of rated current impact and operating duty, therefore structure is also in continuous Optimal improvements.
