Prefabricated Mobile Transformer Substations Assembly Electrical
Substation Used For Power Distribution
Product description
Our YBM, YBP series of prefabricated substation is the combination
of the HV electrical apparatus, transformer, and low voltage
transformer equipments and therefore is used in the high-rise
buildings, residential districts, urban and rural construction,
hi-tech development zone, small and medium size enterprise, mine
and oil fields and the temporary construction sites to receive and
distribute the power.
YBM, YBP series of prefabricated substation is complete set, small
sized, compacted structure, running safely, easy maintenance, and
mobile. And it only takes the 1/10-1/5 of the space of the same
capacity of civil construction distribution, and therefore greatly
reduces the construction cost. It can be used in the ring net
distribution system, double power distribution system or radiator
terminal distribution system. It is the new complete set equipment
used for rural and urban substation construction and reformation.
amorphous alloy substations china
YBM, YBP series of prefabricated substation is fully in accordance
with the standard of SD320-1992 (the technology of Boxes
substation) and the standard of IEC,GB/T 17467-1998 (HV/LV
prefabricated substation). The shell is made of non-metal,
composite board or the steel sheet as per the users.
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.

·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.
·Ordering instruction
1. Conceptual drawing or electrical schematic diagram of main
circuit.
2. Model, specification and quantity of main components.
3. Incoming and outgoing line mode and cable specification, etc.
4. Shell material and appearance: composite plate, steel plate,
stainless steel plate, cement plate, etc.
5. Other order requirements.
