The invention relates to an anti-breaking device for a contact line of an electric locomotive. The anti-breaking device comprises a current mutual inductor, a wind pressure transmitter, a first voltage detection device, a second voltage detection device and an MCU(microprogrammed control unit) control platform, wherein the current mutual inductor is connected with a high pressure introducing circuit of the electric locomotive; the wind pressure transmitter is arranged at the front end of a pantograph improving air source control valve plate of the electric locomotive; the first voltage detection device is connected with a pantograph of the electric locomotive; the second voltage detection device is connected with an accumulator of the electric locomotive; the MCU control platform is connected with the current mutual inductor, the wind pressure transmitter, the first voltage detection device and the second voltage detection device respectively, and according to a signal detected by the current mutual inductor, the wind pressure transmitter, the first voltage detection device and the second voltage detection device, a control signal is outputted to a pantograph control device of the electric locomotive by the MCU(microprogrammed control unit) hardware platform. The anti-breaking device disclosed by the invention can monitor a current passing through the pantograph, the wind pressure of a main air reservoir and the voltage of the accumulator in a real-time manner, and when the detected signal exceeds a set value, the anti-breaking device disclosed by the invention can give out an audible and visual alarm prompt and perform a pantograph reducing protection.
