The invention discloses a controlling device for a pantograph type current collector of an electric locomotive. The device comprises a pilot-operated type pressure regulating valve (3) communicated with an air source, an air bag (8) communicated with a main valve body of the pilot-operated type pressure regulating valve (3), a pressure feedback unit (7) connected between the pilot-operated type pressure regulating valve (3) and the air bag (8) in series, a controlling unit (9) connected with electric locomotive signals and the pressure feedback unit (7), and a vent valve (4) and an inlet valve (5) connected with the controlling unit (9). The vent valve (4) and the inlet valve (5) are communicated with a pilot-operated chamber of the pilot-operated type pressure regulating valve (3) through a gas circuit, and the vent valve (4) and the inlet valve (5) are capable of adjusting the pressure in the pilot-operated chamber. The controlling device for the pantograph type current collector effectively solves the problems that the sensitivity of a pantograph type current collector dynamic regulation controlling device is low and the response time is long. The invention further discloses a controlling method for the pantograph type current collector of the electric locomotive and the electric locomotive comprising the controlling device for the pantograph type current collector.
