METAL-CLAD TRANSFORMER SUBSTATION Russian patent published in 2001 - IPC

FIELD: power supply mains of industrial enterprises. SUBSTANCE: substation has lead-in device on high-voltage side, collecting buses, power transformer, and low-voltage switch-gear. It also incorporates lead-in and line panels mounting circuit- opening and protective devices, ON-operation mechanisms, electricity meters, measuring instruments, and control equipment. Low-voltage switch-gear is assembled of lead-in and line panels with two face sides and common rear side mounted in double-row board. So, stationary circuit-opening and protective devices are equally elevated for easy access to them within size of double-row board as viewed from top. Collecting buses are mounted above boards along each row to form two groups interconnected through jumpers. Installation of low-voltage switch-gear does not require changing the design and arrangement of building components. EFFECT: simplified design, reduced metal input and labor consumption, improved reliability of substation. 5 cl
