Description
技术领域technical field
本发明属于节能和环保交叉技术领域，具体涉及一种全户内变电站诱导通风系统。The invention belongs to the cross-technical field of energy saving and environmental protection, and in particular relates to an induced ventilation system for an all-indoor substation.
背景技术Background technique
随着城市居民对生活环境噪音要求的逐步提高，全户内变电站已成为现在和将来变电站的主要布置方式。变电站电气设备的散热能力是全户内变电站运行能力的主要影响因素，改善变电站室内空间的散热能力，有利于增加变压器的负荷，提高变电站的供电稳定性。With the gradual improvement of urban residents' requirements for living environment noise, all-indoor substations have become the main layout method of substations now and in the future. The heat dissipation capacity of the electrical equipment in the substation is the main factor affecting the operation capacity of the whole indoor substation. Improving the heat dissipation capacity of the substation's indoor space is conducive to increasing the load of the transformer and improving the power supply stability of the substation.
全户内变电站将变压器和散热器分体布置在相邻室内，为了减小对周边环境的噪音污染和防止灰尘进入变压器室，目前通常不在变压器室内设置直接对外的排风口，而是将变压器室排风口分体布置在变压器室和散热器室相邻墙壁的上部。但上述布置方式存在如下不足：从变压器排风口排出的气流会对散热器室内的上升气流形成隔断作用，导致在散热器室下部空间产生大量的涡流或紊流，进入散热器室的冷空气没有与散热器充分接触换热，散热器室下部空间温度梯度较大，导致散热器的散热能力下降，影响变压器的运行能力。在夏季全户内变电站高负荷运行时，变压器室内自然通风散热能力不足，散热器室内环境温度也较高，导致变压器运行温度过高，会影响变电站稳定运行。The whole indoor substation arranges the transformer and the radiator separately in the adjacent room. In order to reduce the noise pollution to the surrounding environment and prevent dust from entering the transformer room, at present, the direct external air outlet is usually not set in the transformer room, but the transformer The room exhaust outlet is arranged separately on the upper part of the adjacent wall of the transformer room and the radiator room. However, the above arrangement has the following disadvantages: the airflow discharged from the transformer exhaust port will form an isolation effect on the upward airflow in the radiator chamber, resulting in a large amount of eddy current or turbulent flow in the lower space of the radiator chamber, and the cold air entering the radiator chamber Without sufficient contact with the radiator for heat exchange, the temperature gradient in the lower space of the radiator chamber is relatively large, resulting in a decrease in the heat dissipation capacity of the radiator and affecting the operating capability of the transformer. During the high-load operation of the indoor substation in summer, the natural ventilation and heat dissipation capacity of the transformer room is insufficient, and the indoor ambient temperature of the radiator is also high, resulting in high operating temperature of the transformer, which will affect the stable operation of the substation.
