Vehicle-mounted movable type substation

The utility model provides a vehicle-mounted movable type substation, which comprises a substation body and a base. The two sides of the base are provided with channel steel pieces. A concealed telescopic supporting leg apparatus is arranged outside the channel steel pieces on both sides of the base. The profile dimension of the substation body is just as that of a standard container, and the bottom of the substation body is provided with container corner fittings. Therefore, the substation can be conveniently connected with the chassis of a transport vehicle. Through arranging the concealed telescopic supporting leg apparatus on the base, the substation is prevented from getting overlarge, so that transportation requirements can be met. When the above product is carried to an operation site, the supporting leg apparatus is unfolded. Meanwhile, the chassis of the transport vehicle is moved away. The supporting leg apparatus is provided with spacing and locking means, thus being prevented from rotating and off
