Electrical cabinets are indispensable equipment in power systems and mainly play the role of protecting, controlling and distributing electrical energy. Electrical cabinets can be divided into various types according to their uses and structural features.
First of all, low-voltage electrical cabinets are the most common type, and their rated voltage is generally below 1000V. Low-voltage electrical cabinets are widely used in various occasions, such as residential buildings, commercial buildings, industrial plants, etc. Its main function is to introduce electric energy from the transmission line into the building and then distribute it to various electrical equipment.
Secondly, the rated voltage of medium-voltage electrical cabinets is generally between 1kV and 35kV, and is mainly used in urban power grids, industrial and mining enterprises, etc. The structure of medium-voltage electrical cabinets is more complex than that of low-voltage electrical cabinets, and requires higher safety and reliability.
In addition, the rated voltage of high-voltage electrical cabinets is generally above 35kV and is mainly used in power transmission and substations in power systems. The structure of high-voltage electrical cabinets is more complex and requires higher insulation and voltage resistance.
To sum up, there are various types of electrical cabinets. Choosing different types of electrical cabinets according to different occasions and uses can better ensure the safe and stable operation of the power system.
