Keywords:
YB□-12/0.4(F.R) Outdoor Prefabricated Substation (European Style)
The YB□-12/0.4 outdoor prefabricated substation (European-style) is widely used in urban grid renovations, residential communities, high-rise buildings, industrial and mining facilities, hotels, shopping malls, airports, railways, oil fields, ports, highways, and temporary power installations—suitable for both indoor and outdoor applications.
· High-voltage switchgear, transformers, and low-voltage switchgear are integrated into a single, highly complete system; featuring comprehensive high- and low-voltage protection, ensuring safe and reliable operation with straightforward maintenance.
· Requires minimal land, reduces investment costs, features a short production cycle, and is highly mobile;
· Flexible and diverse wiring solutions;
· Unique structure: The distinctive honeycomb-style, double-layer (composite panel) enclosure is robust, offering excellent insulation while also promoting efficient heat dissipation and ventilation. It boasts a sleek design, high protection levels, and comes in a variety of durable materials, including stainless steel-titanium alloy, aluminum alloy, cold-rolled steel, and color-coated steel panels.
Normal operating conditions
· Altitude: Not exceeding 1000m; high-altitude products can be customized.
· Ambient temperature: -25°C to +40°C;
· Relative humidity: daily average no more than 95%, monthly average no more than 90%;
· Installation location: Areas free from fire hazards, explosion risks, conductive dust, chemically corrosive gases, and severe vibrations. If these conditions are not met, users may contact our company for further discussion.
Transformer
The intelligent integrated substation features low-loss, oil-immersed, fully sealed transformers from the S20 and S22 series. Alternatively, eco-friendly dry-type transformers with resin insulation or NOMEX paper insulation can also be selected. Additionally, a trolley can be installed at the base, allowing for convenient in-and-out movement of the transformer.
· Diverse styles: available in universal, villa-style, compact, and other designs;
· The high-voltage ring main unit can be equipped with a network automation terminal (FTU) to reliably detect short-circuit and single-phase-to-ground faults, featuring "four remotes" functionality for seamless upgrades in distribution network automation.
High-voltage side
Intelligent integrated substations typically use load switch-fuse combination devices for high-voltage protection. Once a single phase fuse blows, the system triggers a three-phase coordinated trip. Load switches come in various types, including pneumatic, vacuum, and sulfur hexafluoride options, and can be equipped with electric operating mechanisms to enable automated upgrades. The fuses employed are high-voltage current-limiting fuses featuring striker mechanisms, ensuring reliable operation, robust breaking capacity, and performance that meets critical technical specifications—details of which can be found in the table below. For transformers rated above 800 kVA, vacuum circuit breakers such as ZN12, ZN28, and VS1 are recommended for optimal protection.
Low-pressure side
The main switch on the low-voltage side uses universal or intelligent circuit breakers for selective protection; the feeder switches are equipped with a new type of molded-case circuit breaker that features a compact design and minimal arc length, supporting up to 30 circuits. Additionally, an intelligent automatic reactive power compensation device is available, offering users the choice between contactor-based and contactless switching methods.
