一种用于特高压直流输电换流阀的冷却系统
摘要：
本发明提供了一种用于特高压直流输电换流阀的冷却系统，特高压直流输电换流阀包括：由晶闸管换流阀模块13串联组成的换流阀18；直流输电冷却系统包括：一次冷却系统和二次冷却系统；一次冷却系统包括：冷凝器8及其所设的换热组件；二次冷却系统包括：二次冷却介质回流管14、二次冷却装置15、循环泵16及二次冷却介质出口管17。本发明提供的冷却系统维护方便，经济性好，相变冷却系统中的相变冷却介质循环动力由晶闸管和阻尼电阻等元器件热损耗提供，无需外加动力，使整个系统自成独立的自循环系统。
摘要（英）：

The invention provides a cooling system used for an ultrahigh voltage DC power transmission converter valve. The ultrahigh voltage DC power transmission converter valve comprises a converter valve 18formed by series connection of thyristor converter valve modules 13. A DC power transmission cooling system comprises a primary cooling system and a secondary cooling system. The primary cooling system comprises a condenser 8 and the equipped heat exchange component thereof. The secondary cooling system comprises a secondary cooling medium return pipe 14, a secondary cooling device 15, a circulating pump 16 and a secondary cooling medium outlet pipe 17. The cooling system is convenient to maintain and great in economic performance. The phase change cooling medium circulating power in the phasechange cooling system is provided by the thermal loss of the thyristor and the damping resistor and other components without external power so that the whole system is enabled to self-form the independent self-circulating system.
