MODULAR ELECTRIC PLANT AND ITS RECEIVING ASSEMBLY Russian patent published in 2006 - IPC H02B5/02 H01B1/00 

FIELD: power engineering, possible use for construction of supporting structures of sub-stations, distributing devices and other electric plants, meant for receiving, transforming and distributing electric energy of three-phase electric current of industrial frequency 50 Hz in networks with voltages range 35, 110, 150, 220 kV.

SUBSTANCE: modular electric plant consists of electric equipment, receiving assembly and bearing structure, formed of at least one module mounted on foundation , consisting of at least two rows of bearing posts of tubular shape, with at least two of them in each row with forming of flights in longitudinal and transverse directions; bearing beams, supported by bearing posts in each flight of longitudinal direction and mounted in pairs. Modules are constructed so, that bearing beams of separate modules are mutually parallel and/or mutually perpendicular, and electric equipment is mounted on foundation. Receiving assembly consists of at least one current-conducting wire, connected to at least one support, mounted on bearing structure of modular electric plant, while support consists of two polymer isolators, connected along height with forming of rigidity point, and current conducting wire is connected to support by holding assembly. The best variants of inventions from the group are realized with bolt connection of bearing structure elements and polymer isolators.

EFFECT: higher operational reliability of electric plant structures in case of upholding of unification and standardization principles due to development of modules, rational occupation of area occupied by distributing device, possible further expansion of operating electric plants, decreased metal capacity of bearing structure, decreased net costs of mounting operations and operation of electric plant, higher operational reliability of receiving assembly of modular electric plant due to support being capable of receiving static and dynamic loads, increased reliability of receiving assembly of modular electric plant due to development of modules.
