FIELD: electrical engineering; power supply to various projects.
SUBSTANCE: proposed method for power supply to erected or reconstructed structure or complex of structures includes separate laying of power cable lines from at least two independent geographically spaced apart power supplies, installation of modular distribution center in the form of at least one transportable precipitation-proof heated module or three-dimensional prefabricated unit on pre-erected foundation, lengths of opposing external wall pairs of this unit being in definite proportion, and at least two cubicle sections accommodating switching and protective devices for uniform load distribution among users being provided in unit. Equipment is mounted upon installation of three-dimensional unit on foundation for reuse by provision for its removal from foundation, displacement, and connection in power systems of other projects, including those newly erected or reconstructed, or by replacement in emergency situations with similar three-dimensional unit. Method includes laying of new power lines including those at least partially replacing existing ones, or additional power lines, or power supply and distribution networks. Power network has power lines for connecting loads from at least two geographically spaced apart independent power supplies. Optimal arrangement of pieces of equipment, considering their functional applications, facilitates maintenance of power network.
EFFECT: enhanced economic efficiency and service life, facilitated maintenance of power network.
