Description

High Efficiency Indoor Substation Cooling System

technical field

Background technique

The substation is a place to change the voltage. When transmitting electric energy, the voltage needs to be increased through the substation to adapt to long-distance transmission when the power plant outputs electricity. When the high-voltage power reaches the user, the voltage needs to be reduced through the substation. Substations are generally divided into Indoor and outdoor substations.

Indoor substations have been widely used due to their high safety, convenient maintenance and strong scalability. Of course, the main equipment of substations are switches and transformers. When the transformers work, heat will be generated. Intrusive transformers can use heat sinks to dissipate heat, but for transformers in indoor substations, heat dissipation is an important issue. At present, in order to enhance the heat dissipation effect, it is generally used to install a power device such as a fan at the place corresponding to the heat sink at the bottom of the transformer to enhance the air flow. On the one hand, it can accelerate the flow of air, and on the other hand, it can gather cold air and output it to the heat sink. , to further enhance the cooling effect. However, the current installation structure has the following disadvantages: Although the fan gathers and transmits the cold air to the heat sink, it turns into hot air after heat exchange, and most of it is excluded from the transformer room, while the other part remains in the transformer room. The function of the fan at the bottom of the transformer makes the hot air enter from the inlet of the fan and flow to the heat sink, so that the cold air entering the inlet of the fan is reduced, which affects the heat dissipation effect.

Therefore, it is necessary to provide a new cooling system for indoor substations, which can prevent the hot air remaining in the transformer room from entering the inlet of the aerodynamic device, so that the air entering the aerodynamic device is cold air, and enhance the protection of the substation equipment. heat radiation.
