摘要: A blender power unit (BPU) for use in fracturing jobs. The BPU comprises a transformer having an input and an output and configured to receive electrical power via the input at a first voltage to output electrical power via the output at a second voltage; a motor power bus coupled to the output of the transformer; a motor starter bus; at least one motor soft starter having an input coupled to the motor power bus and having an coupled to the motor starter bus; a plurality of electric power relays coupled to the motor power bus and configured to supply electric power from the motor power bus to a load when in a closed state; and a plurality of start electric power relays coupled to the motor starter bus and configured to supply electric power from the motor starter bus to a load when in a closed state.
