Abstract
The invention relates to a cooling device for thermal control cable of turbine end bearing of combined cycle unit, which comprises a protective sleeve, a cooling air pipeline of 1 W thermal control cable and an inlet valve, wherein, the protective sleeve is ganged outside the thermal control cable, the air outlet of the cooling air pipeline of 1 W thermal control cable is connected to the gap between the protective sleeve and the thermal control cable, the cooling air flows along the cooling air pipeline of 1 W thermal control cable into the space between the protective sleeve and the thermal control cable, and the air inlet valve is arranged on the cooling air pipeline of 1 W thermal control cable to connect and disconnect the cooling air pipeline of 1 W thermal control cable. Compared with the prior art, in the invention, protective sleeve is arranged on the thermal control cable, and the cooling air is introduced into the gap between the protective sleeve and the thermal control cable, thus avoiding direct contact between the thermal control cable and the hot air discharged from the turbine exhaust outlet. In addition, the cooling air reduces the ambient temperature in the protective sleeve and produces good cooling effect, which effectively guarantees the safety of the thermal control cable, ensures the safe operation of the unit, and greatly improves safety and reliability.
