Cooling System Circuit Analysis of ±800kV DC Power Transmission Converter Valve

摘要

Converter valve cooling system circuit consisted of internal cooling system circuit and external cooling system circuit. ±800kV DC power transmission converter valve water cooling system circuit was introduced in this paper. Certain cooling medium flow rate through the pressure of the main circulating pump promotion into the outdoor heat exchanger, through outdoor for thermal equipment will change the flow valve produces heat emissions into the air, cooling medium re-entering the thyristor tube converter valve cooling heating element, with a heat back to the main circulating pump inlet, to form a closed loop converter valve cooling system.
