POLE-MOUNTED TRANSFER SUBSTATION Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: pole-mounted transformer substation includes at least one support 1 which carries transformer 2, low-voltage switch-gear 3 and isolator with mobile and immobile contacts 4,5 connecting or disconnecting high-voltage lead-in of transformer 2 from high-voltage power line. Transformer 2 is mounted on support 1 for vertical movement, mobile contacts 4 are set for vertical movement together with transformer 2 and for closing with immobile contacts 5 when transformer is placed into extreme upper position. Substation can include mechanism for vertical movement of transformer 2 and mobile contacts 4 of isolator. EFFECT: increased operational reliability of power supply of small loads. 2 cl, 1 dwg
