The invention relates to a switchgear handcart electric remote operation device and method and belongs to the technical field of electrical equipment. The technical scheme is characterized in that the device comprises a power device (1), a local control panel (6), a local measurement and control device (12) and a remote monitoring host (13). The remote monitoring host (13), the local measurement and control device (12) and the local control panel (6) are connected in sequence. The power device (1) comprises a low-speed motor (2), a small gear (3), a large gear (4) and a transmission connection rod (5). The low-speed motor (2) is connected with the small gear (3); the small gear (3) and the large gear (4) are engaged mutually; the large gear (4) is mutually connected with the transmission connection rod (5); the local control panel (6) is connected with the low-speed motor (2); and the transmission connection rod is connected with a roll-in-roll-out bearing of a handcart switch. The device can achieve a purpose of remote roll-in-roll-out control of the handcart switch, thereby reducing operator on-site operation frequency and improving operation efficiency.
