LOW-POWER PILLAR HOISTING-LOWERING COMPLETE TRANSFORMER SUBSTATION Russian patent published in 2006 - IPC H02B5/02 

FIELD: power engineering, applicable for electric power supply of low-power distributed and remote consumers of residential zones and small plants in towns and farms, for seasonal installation in agricultural production, for farmings, for individual electric power supply of cottages of elite building, in locations and areas with a deep snow cover (frozen snow crust) in snow and not easily accessible locations.

SUBSTANCE: the substation is installed directly on reinforced-concrete power transmission line support and made in the form of a substation moving on a support on two supports of support rollers, installed on a truck with a transformer with movable contacts on truck and fixed contacts installed on the support. Provision of additional devices such as a hoist, lock device, stops, protection high-voltage equipment, low-voltage equipment of operative servicing, protection and registration ensures reliable operation of the substations in the switched-on condition and safety of the substation in its servicing, since the repair and maintenance operations are performed when the truck of the open contacts of disconnectors is lowered to the support base, at a deenergized transformer and the whole electrical equipment of the substation. In this case the other consumers of electric power connected to the high-voltage line are always connected to the network and their supply is not switched-off.

EFFECT: enhanced safety, convenience of service of the transformer substations an reliable electric power supply.
