Abstract
The invention provides a high-voltage load switch with a five-prevention lock. The high-voltage load switch comprises an underframe, a main blade, an arc extinguisher, a fuse and a control cabinet, wherein insulated masts are arranged on the underframe and connected with copper buses for electric conduction; the copper buses, the main blade, the arc extinguisher and the fuse are sequentially connected to form a main loop; and a five-prevention lock device for controlling a wind power load switch is arranged on the underframe. According to the high-voltage load switch with the five-prevention lock, as the five-prevention lock belongs to high-voltage equipment switches, and can force an operator to operate according to the given operation programs, the phenomenon of disordered operation or misoperation is prevented, and the personnel safety of the operator is guaranteed while the smooth circuit operation is ensured.
Description
Technical field
The present invention relates to dynamo-electric manufacturing field, particularly relate to a kind of high voltage load switch with five anti-locks.
