摘要
用电量的增加使得运行产热量大幅增大,导致变压器室温度偏高,这给变电站的安全、可靠运行带来极大的影响。根据变压器室的特点,建立了变压器室内流场的数学模型;通过数值模拟,研究了不同通风工况下的流场分布特点,模拟结果和实际运行的情况一致。可见建立的变压器室流场的数学模型可用于研究变压器室流场分布状态,这对新建变压器室以及已有变压器室改造、优化变压器室通风方案、有效降低变压器室温度都具有重大的指导意义。
The increase of power consumption makes the rapid heat production growth, and leads the temperature of power transformer room much too high, influences the safety and reliability of transformer substation. According to the peculiarities, mathematical model about flow field in power transformer room is established, features of distribution of flow field under different ventilation condition are researched by numerical simulation, the results of numerical simulation are quite consistent. Mathematical model established for power transformer room can be t^ed to research distribution of flow field in power transfarmer room, it has significant guiding sense to new or reshaped power transformer room,, optimizing ventilation project, effectively lowering the temperature of power transformer room.
