Abstract: FIELD: electrical engineering. 
     SUBSTANCE: invention relates to electrical engineering, particularly to power electronics, and can be used in transformer substations. Device for stabilization of three-phase voltage is intended for connection at low side of power transformer of substation. It comprises series-connected input frequency converter with DC link, step-down six-phase high-frequency transformer with a circular rotating field and an output frequency converter, which is a six-phase-three-phase zero cyclo-converter. Input frequency converter increases the frequency in multiples of the number of phases and frequency of the network and comprises a transistor rectifier with PWM with input sinusoidal capacitive current and double-bridge voltage inverter made on the basis of two single-phase bridge circuits with PWM with sinusoidal generation of output currents. Output frequency converter from six-phase voltage at the output of the high-frequency transformer forms an adjustable positive or negative three-phase additional voltage with frequency equal to the network frequency. This adjustable additional voltage, summing up with voltage of secondary winding of power transformer, provides substation consumers with stable voltage. Stabilization of voltage on load is performed by rectifier and double-bridge voltage inverter by voltage deviation of circuit and cyclo-converter as to voltage deviation on load.

Each beam has a suspension device with a lifting device, a suspension device with a rotating shaft, rigging devices in the form of brackets, slings and a hook on a lifting device. After that, a vehicle is fed into the portal system with a load placed on the cradles, which, together with the cradle, is mounted on mobile supports placed between the guides of the portal system using the hydraulic travel of the vehicle suspension. After that, the vehicle is taken out of the work area, and the traction and lifting ring slings are fixed through the lifting shackles of each transverse beam. The traction sling is fixed with one end on the hook of the lifting device, then pulled under the load and with the second end is fixed in a lifting bracket placed at one of the ends of the lifting ring sling, which is also pulled under the load and fixed in the lifting bracket of the traction sling, after which it is pulled out by remote control upward telescopic racks of hydraulic supports. The load placed in the loop formed by the lifting ring sling is lifted above the cradle, then the lifting device is lifted, simultaneously with which the hook and the traction sling also begin to rise and pull the lifting ring sling, which is set in motion due to the rotation of the suspension shaft. The rotational movement is transmitted to the load, its position changes in space by the value of a given angle, upon reaching which the load is already in the changed position is lowered onto the cradle, together with which it is again installed on the vehicle and removed from the portal system. 
     EFFECT: invention simplifies and optimizes the process of tilting large-sized cargo with the provision of the possibility of changing its position and reducing the dimensions in height and/or width during lifting, loading and transportation.
