Description

Box type substation

technical field

The utility model relates to a box type substation.

Background technique

In the power system, box-type substations are widely used. Box-type substations are a kind of factory prefabricated indoor/outdoor compact power distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage power distribution devices according to a certain wiring scheme. Realize functions such as high-voltage power receiving, transformer step-down, and low-voltage power distribution. The box-type substation includes a box body composed of a bottom plate, a wall plate and a top cover. The box body is divided into a high-voltage room, a transformer room and a low-voltage room by a partition. The high-voltage room, the voltage room and the low-voltage room correspond to the high-voltage switchgear, Distribution transformer and low-voltage power distribution device, the whole box is fully enclosed, which can prevent moisture, dust, rats, fire and heat insulation. There are several ventilation holes on the bottom plate for heat dissipation. However, unlike high-voltage switchgear and low-voltage power distribution equipment, distribution transformers will generate a lot of heat during operation, and if the heat is not dissipated in time, the temperature in the transformer room will be too high, and in severe cases, it will affect the normal operation of the transformer. work, and the fully enclosed structure of the existing box-type substation, the ventilation holes of the bottom plate cannot meet the heat dissipation, and the wall board of the box body uses a heat insulation board, although it can play a good role in heat insulation, especially in hot In summer, but in winter, there is the disadvantage that heat is not easy to dissipate.

The utility model has the following beneficial effects:

The wall panels constituting the transformer chamber are composed of inner and outer wall panels arranged at intervals, so that a transition chamber is formed between the inner and outer wall panels. When the temperature inside the transformer chamber is too high, it can pass through the The exhaust fan discharges the hot air in the transition chamber to form a negative pressure, and the hot air in the transformer chamber enters the transition chamber through the communication port opened on the inner wall panel, so that the hot air in the transformer chamber can be discharged in time to prevent the heat from being caused by the heat in the transformer chamber. If it is too high, it will affect the normal operation of the transformer, and the transition chamber can also play a good role in heat insulation in hot summer; the connection port is set on the top of the inner wall, combined with the ventilation hole on the bottom plate, the exhaust fan can make the transformer work. A bottom-up airflow is formed inside the chamber, which is more conducive to discharge all the heat in the transformer chamber; the heat in the transformer chamber can be transferred to the transition chamber through the inner wall board, which is more conducive to the heat transfer in the transformer chamber. Discharge of heat; there are louvers or filters on the connecting port of the inner wall panels, which can prevent rats and dust; the inner and outer wall panels are made of heat-conducting materials, which is conducive to the heat in the transformer room being transferred to the transition zone through the inner wall panels. The heat in the chamber and in the transition chamber is conducive to transfer to the outside of the box, thereby improving the heat dissipation efficiency, especially in winter, this effect is particularly obvious; a temperature sensor connected to the exhaust fan controller is installed in the transformer chamber, and the temperature sensor can be Detect the temperature in the transformer chamber, and transmit the temperature information to the exhaust fan controller. When the temperature reaches a certain level, the controller will start the exhaust fan by itself to perform exhaust and heat dissipation, thereby improving the automation of the utility model.
