Product Description
Product Overview
YBW-12/0.4(F·R) high and low voltage pre-assembled substations (European style) are widely used in urban power grid renovation, residential communities, high-rise buildings, industrial and mining enterprises, hotels, shopping malls, airports, railways, oil fields, docks, highways, and temporary power supply facilities in indoor and outdoor locations.
Model Meaning
Usage Conditions
● Altitude not exceeding 2000m;
● Ambient temperature: -25℃~+40℃;
● Relative humidity: at 25℃, the daily average value should not exceed 95%, and the monthly average value should not exceed 90%;
● Installation location: places without fire, explosion hazards, conductive dust, corrosive gases, and severe vibrations. If the above conditions are exceeded, users can negotiate with our company.
Functional Features
● High voltage switchgear, distribution transformers, low voltage switchgear, energy metering devices, and reactive power compensation devices are combined according to a certain scheme, with strong completeness;
● Complete high and low voltage protection, safe and reliable operation, simple maintenance;
● Occupies less land, saves investment, short production cycle, and is easy to move;
● Flexible and diverse wiring schemes;
● Unique structure: unique honeycomb structure double-layer (composite board) shell is sturdy, heat-insulating, ventilated, aesthetically pleasing, with high protection level. Shell materials include stainless steel titanium alloy, aluminum alloy, cold-rolled plate, and color steel plate options;
● Various types: general type, villa type, compact type, and other styles;
● The high voltage ring network cabinet can be equipped with a network automation terminal (FTU) to achieve reliable detection of short circuits and single-phase grounding faults, with "four remote" functions, facilitating the upgrade of distribution network automation.
Transformer
The intelligent integrated substation uses low-loss, oil-immersed, fully sealed S11, S13 series transformers, and can also use resin-insulated environmentally friendly dry-type transformers. It can be equipped with a small cart at the bottom for easy entry and exit of the transformer.
High Voltage Side
The high voltage side of the intelligent integrated substation generally adopts a load switch-fuse combination for protection. After one phase of the fuse blows, the three-phase linkage trips. The load switch can be selected from pressure gas type, vacuum, sulfur hexafluoride, etc., and can be equipped with an electric operating mechanism for automation upgrades; the fuse is a high voltage current-limiting fuse with an impact device, reliable action, and large breaking capacity. The main technical parameters are shown in the table below. For transformers above 800kVA, ZN12, ZN28, VS1 vacuum circuit breakers can be selected for protection.
Low Voltage Side
The main switch on the low voltage side uses universal or intelligent circuit breakers for selective protection; the outgoing switch uses a new type of plastic shell switch, which is small in size and has a short arc, with up to 30 circuits; the intelligent automatic tracking reactive power compensation device offers both contactor and non-contact switching methods for users to choose.
