35kV vacuum circuit breaker with FTU framework

The utility model relates to a 35kV vacuum circuit breaker with an FTU framework, which comprises a circuit breaker body, the circuit breaker body is connected with an FTU controller, the FTU controller comprises an interphase short circuit fault processing module which judges the occurrence of a fault by detecting the phase current collected inside a boundary switch and comparing the phase current with a fixed value, and when the phase current is larger than the fixed value, tripping is carried out immediately to isolate the fault; and the single-phase earth fault processing module is used for immediately tripping or giving an alarm when the zero-sequence current is greater than a set value when the single-phase earth fault occurs in the user boundary. The beneficial effects of the utility model are that requirements of remote communication are met while system functions are guaranteed, and the number of functional modules can be conveniently increased or decreased to save investment; a wireless communicatio
