FIELD: electrical engineering, applicable for starting of engines and maintenance, for example, of helicopters on airfields as a source of electric supply.
SUBSTANCE: the electric power installation has a DC generator with a drive internal combustion engine, at least two storage batteries, charging units, power supply unit and switching units. The installation is provided with an electric power cable for supply from an outer AC source connected to the power supply unit and charging devices via the switching unit, and an electric socket for power take-off from the AC generator for maintenance of the helicopter. The installation is made in a body divided into two compartments, one of them - accommodates the interconnected AC generator and the drive internal combustion engine installed on a frame, and the other is divided into two closed sections, positioned in the lower one are the storage batteries connected to the switching unit, and in the upper one - two charging units and the power supply unit, with the installation control unit placed above it. The control console is protected from the environment by an organic glass plate. The storage batteries are positioned in containers made on sleds, and the containers are provided with plug connecters used for connection of the storage batteries to the switching unit. The installation is provided with one more plug connector for take-off of DC power for ground maintenance of the helicopter on-board control systems. The power electric cable for installation supply from the outer AC power source is positioned on the handles of the rear wall of the double-section body. The power electric cable for take-off of DC power for starting of gas-turbine engines is positioned on the handles of the cover of the body engine compartment. The installation is mounted on a wheeled chassis, in front on one support with a telescopic folding pole in an eye between the wheels turning in the horizontal plane, and the pole - in the vertical plane fastened by a bracket on the body.
EFFECT: enhanced mobility and reliability in operation of the power installation.
