Transformer

The intelligent integrated substation adopts low-loss, oil-immersed, fully-sealed S9, S10, and S11 series transformers, as well as resin-insulated or NOMEX paper-insulated environmentally friendly dry-type transformers.

High Pressure Side

The high voltage of the intelligent integrated substation is generally protected by a load switch-fuse combination electrical appliance. After one phase of the fuse is blown, the three-phase linkage trips. The fuse is a high-voltage current-limiting fuse with an impactor, which has reliable action and large breaking capacity. The main technical parameters are shown in the table below. For transformers above 800kVA, vacuum circuit breakers such as QCE4, QCE2, and QCE1 can be used for protection.

Low Pressure Side

The main switch on the low-voltage side adopts a universal or intelligent circuit breaker for selective protection; the outgoing switch adopts a new type of plastic case switch, which is small in size and short in arcing, and can reach up to 30 circuits; intelligent automatic tracking reactive power compensation device with contactor There are two switching methods of contactless and non-contact for users to choose.
