summary:
Ybw-12 / 0.4 outdoor prefabricated substation (European style) is widely used in urban power grid reconstruction, residential quarters, high-rise buildings, industrial and mining, hotels, shopping malls, airports, railways, oil fields, wharves, expressways and temporary power facilities.
 
High voltage switchgear, transformer and low-voltage switchgear are Trinity with strong integrity;
 
Perfect high and low voltage protection, safe and reliable operation and simple maintenance;
 
Less land occupation, less investment, short production cycle and easy to move;
 
The wiring scheme is flexible and diverse;
 
Unique structure: unique honeycomb structure, double-layer (composite plate) shell is firm, heat insulation and ventilation, beautiful, high protection level, the shell materials include stainless steel qinalloy, aluminum alloy, cold-rolled plate, color steel plate;
 
Model meaning:
 
 
Service conditions:
 
Altitude: no more than 1000m, high altitude products can be customized;
 
Environment temperature: - 25 ℃ ~ + 40 ℃
 
Relative humidity: the daily average value shall not be greater than 95%, and the monthly average value shall not be greater than 90%;
 
Installation site: no fire, explosion, conductive dust, chemical corrosive gas and violent vibration. If the above conditions are exceeded, the user can consult with our company.
 
Transformer selection:
 
Intelligent integrated substation adopts low loss, oil immersed, fully sealed S9, S10, S11 series transformers, or resin insulation or Nomex Paper Insulation environment-friendly dry-type transformer. The bottom can be equipped with a car, and the transformer can be easily in and out.
 
Various types: universal, villa, compact, etc;
 
High voltage ring network cabinet can be equipped with network automation terminal (FTU) to realize reliable detection of short circuit and single-phase grounding fault, with "four remote" function, which is easy to upgrade distribution network automation.
 
High voltage side design:
 
The high voltage of intelligent integrated substation is generally protected by load switch fuse combination apparatus. After one phase of fuse is fused, three-phase linkage trip occurs. The load switch can be selected as air compressor type, vacuum type, sulfur hexafluoride and other types. It can be equipped with electric operation mechanism to realize automatic upgrading. The fuse is a high-voltage current limiting fuse with impact device, which has reliable action and large breaking capacity The parameters are shown in the table below. For transformers above 800kVA, ZN12, ZN28, VS1 vacuum circuit breaker protection can be selected.
 
Low voltage side design:
 
The main switch at the low-voltage side adopts universal or intelligent circuit breaker with selective protection; the outgoing switch adopts new plastic shell switch with small volume and short arcing, up to 30 loops at most; intelligent automatic tracking reactive power compensation device has two switching modes of contactor and non-contact for users to choose.
