The intelligent integrated substation adopts low loss, oil immersed, fully sealed S9, S10, and S11 series transformers, and can also choose resin insulated or NOMEX paper insulated environmentally-friendly dry type transformers. The bottom can be equipped with a small car, and the transformer can be easily accessed.
Intelligent integrated substations generally use a combination of load switch and fuse for high-voltage protection. After one phase of the fuse is fused, the three-phase linkage is tripped. The load switch is available in compressed air, vacuum, sulfur hexafluoride, and other types, and can be equipped with an electric operating mechanism to achieve automation upgrade; The fuse is a high-voltage current limiting fuse with an impactor, which is reliable in operation and has a 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.
