The invention discloses a transformer area fault positioning method and system based on marketing and distribution integration, and the method comprises the steps of injecting a pulse signal from thetail end of a line branch, and receiving a sensing confirmation message sent by each fault indicator on a line in response to the pulse signal and an identity label thereof; determining a network topology structure according to the message, the identity label and the position of an outlet circuit breaker on the branch line; and according to the network topology structure, determining a network node relationship between each fault indicator and the circuit breaker on the line and the fault data sent by each fault indicator and the circuit breaker when a fault occurs, and positioning the fault to obtain a transformer area fault positioning result. According to the invention, the marketing and distribution information sharing is realized, and the problems of incomplete fault identification information and difficult p
