FIELD: rail roads.
SUBSTANCE: invention relates to rail break control devices on electrified sections of railways. The device comprises a comparison element, an adder, two threshold elements, a voltage divider, a differentiating device and a rail break detection unit. The device is additionally equipped with two current sensors in the rail threads, two amplifiers, an element with a dead zone, closing and opening electronic switches.
EFFECT: automatic control of rail break.
