The invention discloses a pantograph spring barrel, a pantograph and an electric locomotive, the spring barrel comprises a barrel body and a shaft rod, a spring is arranged in the barrel body, the shaft rod is installed in the barrel body in a clearance fit mode, the variable stiffness spring is arranged on the periphery of the shaft body in a sleeving mode, and the shaft rod is made of a magnet material. The spring is a rigidity-variable spring. According to the invention, the vibration of the shaft rod is weakened and the current collection stability is improved by utilizing the effects of electromagnetic damping and the variable-rigidity spring.
