Comparative Analysis of Similarities and Differences of Valve Cooling Systems

Since the domestic valve cooling system and valve cooling system equipment are quite different in terms of structural configuration, control and protection logic, the operation methods are also quite different. In the pole control system, the ambient temperature used for overload capacity calculation depends on the maximum value of the ambient temperature measured by the two-valve groups. When the valve group converter transformer is not charged, the default ambient temperature of the valve group is 2°C. When the valve group converter transformer is charged (the valve group is unlocked or locked), the valve group will use the measured ambient temperature to participate in the ambient temperature calculation of the maximum value. Therefore, the ambient temperature at which any valve group sends pole control will affect the overload capacity of the pole.
