The invention provides a combined type transformer with an intelligent communication demarcation circuit breaker switch function. The combined type transformer comprises a cabinet body; a high voltage chamber is arranged at the left side of the front of the cabinet body; an intelligent communication demarcation circuit breaker switch cabinet is arranged at the inner part of the high voltage chamber; a main low voltage chamber is arranged at the right side of the front of the cabinet body; a low voltage incoming cabinet is arranged at the inner part of the main low voltage chamber; a low voltage chamber is arranged at the right side of the cabinet body; an outgoing cabinet and a capacitor cabinet are arranged at the inner part of the low voltage chamber; the low voltage parts are connected through a busbar. The combined type transformer with the intelligent communication demarcation circuit breaker switch function not only has a demarcation short-circuiting function of cutting off T joint of a 10 KV main grid rapidly when a user incoming side is in fault, but also has no need to consider the factors of components and parts such as thunderstorm prevention, mildew prevention and ageing prevention while having a complete and powerful collection function of a user network, so that the combined type transformer becomes smaller and more exquisite in volume; materials are saved, and manufacturing difficulty and manufacturing cost are reduced.
