Product details
YB Intelligent Pre installed Substation Purpose:
Widely used in urban power grid renovation, residential communities, high-rise buildings, industrial and mining areas, hotels, shopping malls, airports, railways, oil fields, docks, highways, as well as temporary power facilities and other indoor and outdoor places.
Functions and characteristics of YB intelligent prefabricated substation:
1. High voltage switchgear, transformers, and low-voltage switchgear are integrated in one, with strong completeness;
2. Complete high and low voltage protection, safe and reliable operation, and simple maintenance;
3. Small land occupation, low investment, short production cycle, and convenient mobility;
4. Flexible and diverse wiring schemes;
5. Structure: Honeycomb structure double-layer (composite board) shell is firm, with insulation, heat dissipation, ventilation, beauty, and high protection level. The shell materials include stainless steel alloy, aluminum alloy, cold-rolled plate, and color steel plate;
6. Diverse styles: universal, villa, compact, and other styles;
7. The high-voltage ring main unit can be equipped with a network automation terminal (FTU) to achieve reliable detection of short circuits and single-phase grounding faults, with the "four remote" function, making it easy to upgrade the distribution network automation.
YB Intelligent Prefabricated Substation Normal Use Condition
1. Altitude not exceeding 1000m;
2. Environmental temperature: -25 ℃ -+40 ℃;
3. Relative humidity: daily average not exceeding 95%, monthly average not exceeding 90%;
4. Installation location: A place without fire, explosion hazards, conductive dust, corrosive chemical gases, and severe vibrations. If the above conditions are exceeded, users can negotiate with our company.
YB intelligent prefabricated substation transformer
Intelligent integrated substations use low loss, oil immersed, fully sealed S9, S10, S11 series transformers, or environmentally friendly dry-type transformers with resin insulation or NOMEX paper insulation. The bottom can be equipped with a small car, and the transformer can be easily accessed.
YB intelligent prefabricated substation high pressure measurement
Intelligent integrated substations generally use load switch fuse combination electrical protection for high voltage. After one phase of the fuse is blown, the three phases are interlocked and tripped. The load switch can be selected from 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 operates reliably and has a large breaking capacity. The main technical parameters are shown in the table below. For transformers above 800kVA, QCE4, QCE2, QCE 1 and other vacuum circuit breakers can be used for protection.
YB Intelligent Prefabricated Substation Low Pressure Measurement
The low-voltage side main switch adopts universal or intelligent circuit breakers for selective protection; The outgoing switch adopts a plastic shell switch with small volume, short arcing, and up to 30 circuits; Intelligent automatic tracking reactive power compensation device, with two switching modes for users to choose from: contactor and non-contact.
