The invention provides a remote operation device for a 10-20 kV distribution transformer. The remote operation device is characterized by comprising a wireless communication unit, a signal conversion judging unit and a high voltage circuit breaker operation unit, wherein the wireless communication unit comprises a wireless transmitting module and a wireless receiving module; a signal output end of the wireless receiving module is connected with a signal input end of the signal conversion judging unit; first and second driving signal output ends of the signal conversion judging unit are respectively connected with closing and opening signal input ends of the high voltage circuit breaker operation unit; and closing and opening state signal output ends of the high voltage circuit breaker operation unit are respectively connected with first and second signal input ends of the wireless transmitting module. By using a technical scheme provided by the invention, operators at a distribution service centre can remotely control the operation in any place without electricians going to an equipment field when transformer equipment of a distribution system is needed to be put into use or exited the operation.
