METHOD OF CONTROLLING CURRENT-CARRYING DEVICE OF A SUBWAY CAR AND A CURRENT-COLLECTING DEVICE FOR REALIZING THE METHOD Russian patent published in 2019 - IPC B60L5/39 

FIELD: electrical equipment; transportation.

SUBSTANCE: group of inventions relates to current collectors of vehicles. Method of controlling the current collector of a subway car involves changing the current collector from an operating position to an inoperative position and switching the current collector from a non-operating position to a working position. At that, in order to transfer current collector from non-working position to electric power supply to electric power equipment of car, pressure is first supplied to pneumatic cylinder for squeezing to release load from working spring to locking mechanism. Pressure is then forced into the pneumatic cylinder to unlock and the locking mechanism is disengaged. Pressure is then released from the pneumatic cylinder for squeezing, wherein the shoe is pressed to the current-conducting rail, and thereafter, pressure is released from the pneumatic cylinder for unlocking to return the locking mechanism to the initial position. Also disclosed is a current receiving device for realizing said method.

EFFECT: technical result consists in improvement of reliability in extreme situations and improved safety of subway cars.
