ABSOLUTE NETWORK OF METROPOLITEN LINES WITH CONTINUOUS NUTRITION OF CARS Russian patent published in 2019 - IPC B60M3/04 B60M1/30 B60M7/00 

FIELD: electricity.

SUBSTANCE: invention relates to electrical contact networks. Absolute traction network of metro lines with continuous power supply of cars contains an insulating joint of the contact rail (CR) and active sectioning nodes (ASN). At the same time, the absolute traction network of subway lines retains the traditional control circuit of the disconnectors due to the use of bipolar disconnectors and allows the partitioning of the CR in any place. At the same time, the absolute traction network, that is, non-reinforced through the use of the maximum number of cables in the supply lines and independent of the types of cars. At the same time, linear and reserve disconnectors can be installed both in the tunnel near the CR, and at the pull-down substations, and the linear ones can be installed directly in the RU-825 cells.

EFFECT: ensuring continuous power supply of cars.
