Outdoor Electric Compact Transformer Substation 33KV 400V YB
Prefabricated Substation Used In Ethiopia Uzbekistan
Product description
YB-12/0.4 series prefabricated substation is suitable for AC50HZ,
6KVand 12KV power system, as a power of acceptance and
distribution. It is widely used in industrial and mining
enterprises, residential quarters, hospital, mall, high-rise
buildings and other distribution systems.
The European type substation, is a complete set of new power
transformer equipment developed by our company on the basis of
transformation of national urban network making the optimal
combination for the oil-immersed sealed power transformer and high
and low voltage electrical components. Through structure
optimization, the switchgear shall be miniaturized to extreme
extent which greatly reduce the occupied area of the combined
transformer with such advantages as small volume, low noise,
reliable power supply, reasonable structure, blexible for
installation, easy for operation and capable of going deep into the
load center to maximum extent, etc.It can assemble network
automation terminal (FTU) in the high-voltage ring network cabinet,
realize the reliable detection of short circuit and single-phase
grounding fault, and has the function of "four remote", which
facilitates the automatic upgrade of network distribution. It is
widely used in residential quarters commercial centers stations
industrial and mining enterprises airports railroads schools
hospitals, high-rise buildings and places.
· Use condition
1. The maximum ambient air temperature shall not exceed 45℃, and
the minimum shall not exceed - 45℃;
2. The altitude shall not exceed 1000m. If special customized
transformers and low-voltage components are used, the altitude can
reach 4000m;
3. It shall be placed in a place with a vertical inclination of no
more than 5°and no severe vibration or impact;
4. The air humidity is not more than 90% (+ 25℃);
5. Gas place without conducting dust, explosion hazard, corrosion
metal and electrical components;
6. Outdoor wind speed shall not exceed 35m/s.
7. If the above normal use environment conditions are exceeded, the
customer can customize it with our company.
· Structure characteristic
1. The box shell is designed according to the actual situation with
reference to foreign advanced technology, and it has the
characteristics of firmness, heat insulation and ventilation,
stable performance, corrosion prevention, dust prevention,
waterproof, small animal prevention, beautiful appearance, etc.
There are many choices of shell materials, such as steel plate,
composite plate, stainless steel plate, cement plate, etc.
2. There are high-voltage switchgear such as xgn15, hxgn17 or
kyn28a and other equipment in the high-voltage room for
high-voltage incoming line, high-voltage metering and high-voltage
outgoing line. The high-voltage side can be arranged with ring
network power supply, terminal power supply, dual power supply and
other power supply modes, and high-voltage metering elements can
also be installed to meet the requirements of high-voltage
metering. The main switch is generally load switch or vacuum
circuit breaker, with compact and reasonable structure and perfect
anti misoperation function.
3. There are low-voltage switchgear such as GGD, GCS or MNS and
other equipment in the low-voltage room for low-voltage incoming
line, reactive compensation and low-voltage outgoing line. The
low-voltage side adopts the panel type or cabinet mounted structure
to form the power supply scheme required by the user, which can
meet the power distribution, lighting distribution, reactive
compensation, electric energy metering and other functions. The
main switch generally adopts the universal circuit breaker or the
intelligent circuit breaker, which is flexible in installation and
simple in operation.
4. The transformer in the transformer room can use the fully sealed
oil immersed transformer or dry-type transformer. The oil immersed
transformer can be S9, S11, S13 or SH15, and the dry-type
transformer can be scb10, scb11, SGB10 or scbh15. According to the
actual needs of customers, it can be configured freely, which has
the advantages of more selectivity and flexibility.
5. The cover of the box is designed with double-layer structure,
and the interlayer is filled with foam plastics, which has good
heat insulation function. The transformer room is equipped with
anti condensation and automatic temperature control monitoring,
heating and cooling devices. A dust-proof device is arranged on the
position of the door sheet and the louver outside the side plate.
Note: Due to continuous product improvement, the dimensions provided in
this sample are for reference only. If necessary, our company can
design and produce according to user requirements. Please contact
the company in time.
