Intruduction:

Substation: "change the place of voltage, control and distribution of electric energy. The small size of the call".

Substation  is a power system in which a number of devices are assembled and used to cut off or connect, change or adjust the voltage.

Substation can be divided into: hub substation, terminal substation; step-up substation, step-down transformer substation; power system substation, industrial and mining substation, railway substation (27.5kV, 50Hz); 1000kV and 750kV, 500kV and 330kV and 220kV, 110KV, 66kV, 35kV, 10kV, 6.3kV and voltage grade substation; 10kV substation; box type substation.

The main equipment and connection mode of the transformer substation are different according to their function.
