FIELD: electrical engineering; power distribution. SUBSTANCE: modular distribution transformer substation has high-voltage entrance bay connected to power cables, two power transformers, and low-voltage switchgear. Novelty is that high-voltage entrance bay is made in the form of double-section distribution center. Each section accommodates set of cubicles with switching, protective, and grounding devices. Each section is built of modules U-shaped as viewed from top and joined together during installation to form single box-configured section room with common door. Each power transformer is mounted in separate three-dimensional module made in the form of roof-panel duct, longitudinal walls, and lateral ones provided with door, Mentioned integrated modules of cubicle sets are abutting against one another and/or one of them is abutting against one three-dimensional power transformer module. EFFECT: enhanced economic efficiency, facilitated installation and wiring, enhanced operating reliability and service life, facilitated maintenance of substation. 25 cl, 21 dwg
