YBW-12/0.4 outdoor prefabricated substation (European) is widely used in urban power grid reconstruction, residential quarters, high-rise buildings, industrial and mining, hotels, shopping malls, airports, railways, oil fields, terminals, highways, and temporary power facilities. Inside and outside places.
1. High-voltage switchgear, transformer, low-voltage switchgear, three-in-one, strong set;
2. High and low voltage protection, safe and reliable operation and simple maintenance;
3.Small land occupation, low investment, short production cycle and convenient movement;
4. Flexible wiring scheme;
5. Unique structure: unique honeycomb structure double-layer (composite board) shell is firm, heat-insulating, heat-dissipating, beautiful, high level of protection, shell material is stainless steel alloy, aluminum alloy, cold-rolled plate, color steel plate optional;

The intelligent integrated substation uses low-loss, oil-immersed, fully-sealed S9, S10, and S11 series transformers. It can also be used with 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.
1. Various types: general style, villa type, compact type, etc. 2. High-voltage ring network cabinet can be equipped with network automation terminal (FTU) to achieve reliable detection of short-circuit and single-phase grounding faults. It has "four remote" function, which is convenient for automatic distribution network upgrade.

The intelligent integrated substation high voltage generally adopts the load switch-fuse combination electric appliance protection. After the fuse is blown by one phase, the three-phase linkage trips, the load switch has the types of compressed air, vacuum, sulfur hexafluoride, etc. The operating mechanism realizes automatic upgrade; the fuse is a high voltage current limiting fuse with a striker, the action is reliable, and the breaking capacity is large. The main technical parameters are shown in the following table. For transformers above 800kVA, vacuum circuit breakers such as ZN12, ZN28 and VS1 can be used for protection.

The low-voltage side main switch adopts a universal or intelligent circuit breaker for selective protection, the outlet switch adopts a new plastic shell switch with small volume, short arcing. Up to 30 loops; intelligent automatic tracking reactive power compensation device, with contactor and non-contact switching methods for users to choose.
