normal condition
◇ Altitude not exceeding 1000m;
◇ Environmental temperature: -25 ℃~+40 ℃;
Relative humidity: daily average not exceeding 95%, monthly average not exceeding 90%;
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.
Function and characteristic
High voltage switchgear, transformers, and low-voltage switchgear are integrated into one, with strong completeness;
Complete high and low voltage protection, safe and reliable operation, and simple maintenance;
◇ Small footprint, low investment, short production cycle, and convenient mobility;
◇ Flexible and diverse wiring schemes;
◇ Structure: Honeycomb structure double-layer (composite plate) shell is firm, insulated and ventilated, beautiful, and has a high level of protection. The shell material includes stainless steel alloy, aluminum alloy, cold-rolled plate, and color steel plate to choose from;
◇ Diverse types: universal, villa, compact, and other styles;
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, which facilitates the upgrade of distribution network automation.
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.
High voltage side
Intelligent integrated substations generally use a combination of load switches and fuses for high voltage protection. 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. For transformers above 800kVA, vacuum circuit breakers such as QCE4, QCE2, and QCE1 can be used for protection.
low-pressure side
The low-voltage side main switch adopts universal or intelligent circuit breakers for selective protection; The outgoing switch adopts a new 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.
