The invention discloses an intelligent temperature control system for protecting the arc-extinguishing medium of an SF6 circuit breaker in an alpine region from being liquefied, and relates to the high-voltage electrical field. The invention aims at effectively increasing the temperature of the arc-extinguishing medium of the SF6 circuit breaker and the temperature of the working environment of an operating mechanism. The system consists of a heating band unit, a temperature display adjustment unit, a temperature collection and transmission unit, and a self-powered supply unit. The temperature collection and transmission unit enables the temperature data of an arc extinguish chamber and a circuit breaker cross beam box to be transmitted to the temperature display adjustment unit in a wireless mode, and the temperature display adjustment unit carries out the comparison processing of the data. A subsequent heating band circuit is driven to adjust the internal temperature of the arc extinguish chamber and the circuit breaker cross beam box. The system achieves the closed-loop control, effectively increases the temperature of the arc-extinguishing medium of the SF6 circuit breaker and the temperature of the working environment of the operating mechanism, and improves the work stability of the circuit breaker.
