Description

Technical Field

[0001] The invention relates to the technical field of temperature detection devices for prefabricated cabins of transformer substations, and in particular to a temperature detection device for prefabricated cabins of transformer substations and a ventilation and heat dissipation system. Background Art

[0002] Substation prefabricated cabin, as the name implies, is a prefabricated building that can be directly installed on site without the need for on-site pouring, saving a lot of time and labor costs. The prefabricated cabin integrates control, power distribution, cable joints, integrated machine room and other functions, and can be quickly combined into a new substation. Substation prefabricated cabin is mainly used in urban power grid construction and expansion projects, industrial and mining enterprise power distribution systems, new energy power stations, airports, subways, highways and other infrastructure fields. Due to the use of prefabricated cabin construction methods, it can greatly shorten the construction period and improve the construction quality of the project. At the same time, the impact on the on-site environment is also small. The substation prefabricated cabin needs to have a good ventilation and heat dissipation system during construction. Therefore, a substation prefabricated cabin temperature detection device and ventilation and heat dissipation system are needed to meet people's use needs.

[0003] At present, the prefabricated cabins of substations are ventilated and cooled by simple air circulation. This ventilation and cooling method is prone to cause rainwater to enter the interior of the prefabricated cabin of the substation through the ventilation and cooling system on rainy days, thereby causing short circuits in electrical components. At the same time, it is easy for dust and lint in the air to enter the interior of the prefabricated cabin of the substation, thereby causing short circuits in the prefabricated cabin of the substation, posing a safety hazard. Based on this, we propose a temperature detection device and ventilation and cooling system for the prefabricated cabin of the substation. Summary of the invention
