Product Overview
Widely used in urban power grid renovation, residential communities, high-rise buildings, industrial and mining, hotels, shopping malls, airports, railways, oil fields, docks, highways, temporary and temporary electricity facilities, and other indoor and outdoor places.
Function and Characteristics
◇ High voltage switchgear, transformer, and low-voltage switchgear are integrated, 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;
◇ Unique Structure: Unique honeycomb structure with double-layer (composite plate) outer shell that is sturdy, insulated and ventilated, beautiful, and has a high level of protection. The outer shell materials include 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 cabinet can be equipped with a network automation terminal (FTU) to achieve reliable detection of short circuits and single-phase grounding faults, and has the "four remote" function, which is convenient for upgrading distribution network automation.
Normal Usage Conditions
◇ The altitude shall not exceed 2000m;
◇ Environmental temperature: -25 ℃ ~+40 ℃ ;
◇ Relative humidity: The daily average value shall not exceed 95%, and the monthly average value shall not exceed 90%;
◇ Installation site: A place without fire, explosion hazards, conductive dust, chemical corrosive gases, and severe vibrations. If the above conditions are exceeded, users can negotiate with our company.
Transformer
The intelligent integrated substation adopts low loss, oil immersed, fully sealed S9, S10, and S11 series transformers, and can also choose 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.
High Voltage Side
Intelligent integrated substations generally use a combination of load switch and fuse for high-voltage protection. After one phase of the fuse is fused, the three-phase linkage is tripped. The load switch can be selected in various types such as compressed air, vacuum, and sulfur hexafluoride, and can be equipped with an electric operating mechanism to achieve automation upgrading; The fuse is a highvoltage current limiting fuse with an impact device, which is reliable in operation and has a large breaking capacity. The main technical parameters are shown in the table below. For transformers above 800kVA, vacuum circuit breakers such as QCE4, QCE2, and QCE1 can be used for protection.
Low Voltage Side
The low-voltage side main switch adopts universal or intelligent circuit breakers for selective protection; The outgoing switch adopts a new type of plastic shell switch with small volume, short arc length, and up to 30 circuits; The intelligent automatic tracking reactive power compensation device has two switching methods for users to choose from: contactor and contactless.
