Abstract
The utility model discloses a high-voltage load switch equipped with a five-prevention lock. The high-voltage load switch equipped with a five-prevention lock comprises a base rack, a main cutter blade, an arc extinguishing device, a fuse and a control box, wherein the base rack is provided with insulation columns which are connected with copper bus bars for electric conduction. A main return circuit is formed by orderly connecting the copper bus bars, the main cutter blade, the arc extinguishing device, and the fuse; and the base rack is provided with a five-prevention lock device for controlling a wind power load switch. Through the above mode, the high-voltage load switch equipped with the five-prevention lock is provided, the five-prevention lock is a high-voltage equipment switch and is capable of compelling an operator to operate according to a set operation program, disordered operation or mal-operation phenomena can be eliminated, and personal safety of the operator is guaranteed while stable circuit work is ensured.
Description
Technical field
The utility model relates to dynamo-electric manufacturing field, particularly relates to a kind of five anti-lock high voltage load switches that have.
