Power transformation framework and transformer substation
The invention relates to a power transformation framework and a transformer substation, the power transformation framework comprises a framework column, a framework beam and a turbulent flow structure, one end of the framework column is connected with the ground, and the other end of the framework column is connected with the framework beam; the framework girder is provided with an upper half portion and a lower half portion which are symmetrical about the horizontal plane, and the turbulent flow structure is arranged on the outer surface of the upper half portion and/or the outer surface of the lower half portion of the framework girder in a protruding mode so that the flowing path of airflow on the outer surface of the upper half portion of the framework girder can be different from the flowing path of airflow on the lower half portion of the framework girder. According to the technical scheme, the turbulent flow structure is arranged on the outer surface of the upper half part and/or the outer surface of the lower half part of the framework girder, so that when airflow blows to the framework girder, the flowing direction and the flowing path of the airflow are changed under the interference of the turbulent flow structure; therefore, the phenomena that the air flow generates vortex shedding behind the framework girder and vortex excitation occurs to the framework girder are avoided, the stability of the framework girder is improved, and the service life of the framework girder is prolonged.
本公开涉及一种变电构架以及变电站，变电构架包括构架柱、构架梁以及扰流结构，构架柱的一端与地面连接，构架柱的另一端与构架梁连接；构架梁具有关于水平面对称的上半部和下半部，扰流结构凸出设置在构架梁的上半部的外表面和/或下半部的外表面，以能够使得气流在构架梁的上半部的外表面的流动路径与气流在构架梁的下半部的流动路径不同。通过上述技术方案，通过在上述构架梁的上半部的外表面和/或下半部的外表面设置扰流结构，当气流吹向构架梁时，在扰流结构的干扰下，改变了气流的流动方向及流通路径，以避免气流在构架梁的后方产生涡流脱落及构架梁发生涡流激振的现象，从而提升构架梁的稳定性及使用寿命。
