The invention discloses an extra high voltage converter transformer cooler redundancy control system and method, belonging to the electric power technology field. The extra high voltage converter transformer cooler redundancy control system comprises a DC control protection system A1, a DC control protection system B1, a measurement and control device A2, a measurement and control device B2, a sensor module, a signal multiplication device, a switching device and a converter transformer cooling device. The extra high voltage converter transformer cooler redundancy control system and method provide a scheme including double measurement and control devices and the switching device. When the measurement and control devices A,B work independently in a double-host working mode , a working mode of switching between a host output signal and a standby output signal is adopted on the switching device side. The extra voltage converter transformer cooler redundancy control system and method can switch from one side devic
