The invention relates to an indoor high-voltage intelligent vacuum circuit breaker, and the circuit breaker comprises a mechanism box and an intelligent protection and control device disposed in the mechanism box. The circuit breaker also comprises a combined transformer module which is formed by the casting of a current transformer and a voltage transformer. The combined transformer module and a vacuum arc-extinguishing chamber are cast together to form an embedded pole which is fixedly connected to the mechanism box. The embedded pole is also fixedly provided with a secondary binding post fixedly connected with the mechanism box. The interior of the secondary binding post is provided with a signal line, wherein one end of the signal line is connected with the combined transformer module, and the other end of the signal line is connected with the intelligent protection and control device. The embedment technology is employed for the embedment of the combined transformer module and the vacuum arc-extinguishing chamber, thereby forming the vacuum embedded pole. The circuit breaker is simple in wiring, is small in interference from the outside, and is low in loss. Moreover, the secondary binding post plays a role in supporting, and guarantees the sufficient strength when a main loop is in a short circuit state/ during a peak withstand current test and an open-circuit fault current test.
