High voltage solid-state soft start cabinet is designed as cabinet structure. The cabinet frame is welded with 50 angle steel, which is firm and reliable. The cabinet is designed in the way of incoming and outgoing lines at the bottom of the cabinet. Before putting into operation, it is only necessary to connect the high-voltage solid-state high-voltage soft start cabinet in series between the high-voltage switch cabinet and the high-voltage motor. See the following figure for the specific electrical primary scheme.

The primary devices of high-voltage solid-state soft start cabinet include: Vacuum AC contactor, series thyristor module, overvoltage protector, high-voltage current transformer, high-voltage voltage transformer, soft start controller, power module, etc. The internal structure of high-voltage soft start cabinet is simple, each part is modular, and the maintenance is simple and convenient. See Figure 1.4 for the layout of devices in the cabinet.
