YBM-12 0.4 Outdoor Prefabricated Substation ISO9001 Customizable

Product Description:
YB(M)-10/0.4 European-style box substation is a compact power distribution equipment that arranges high-voltage, distribution transformer, low-voltage distribution device and electric energy metering equipment into one according to a certain line scheme, occupying a small area.
It is suitable for urban public power distribution, high-rise buildings, residential areas, industrial and mining enterprises, oil fields and temporary construction sites.

Product features:
1, Advanced technology, safe and reliable
Body part adopts domestic and foreign advanced technology and craft, case generally adopts aluminium zinc steel plate, frame with a standard container material and production process, good anti-corrosion performance, guarantee the 20 years does not rust, photosensitive plate adopts aluminium alloy gusset plate, sandwich fireproof insulation materials, the casing installation of air conditioning and dehumidification equipment, equipment operation is not affected by natural climate environment and pollution of the outside world, It can ensure normal operation in the harsh environment of -40℃~+40℃.

2, high degree of automation
Total station intelligent design, protection system adopts microcomputer integrated automation substation equipment, installation, which can realize "four control", namely, telemetry, remote communication, remote control, remote regulating, each unit shall be independent operation function, protection function is all ready, can be set up the operation parameters of the distance, to control the casing humidity, temperature, and meet the requirements of the unattended.

3, Factory prefabrication
During the design, as long as the designer makes the design of the main wiring diagram and equipment outside the box according to the actual requirements of the substation, the specification and model of the box transformer provided by the manufacturer can be selected. All the equipment is installed and tested in the factory at a time, which can truly realize the factory construction of the substation and shorten the design and manufacturing cycle. On-site installation only needs box positioning, cable connection between boxes, outgoing cable connection, protection calibration, transmission test and other debugging work, the entire substation from installation to operation only need about 5 to 8 days, greatly shortening the construction period.

4, Flexible combination mode
European box transformer due to the compact structure, each box constitute an independent system, which makes the combination of flexible, we can all use the box type, that is, 35kV and 10kV equipment all box installation, the composition of the full European box substation; Outdoor installation of 35kV equipment and installation of 10kV equipment and control and protection system box can also be used. This combination mode is especially suitable for the transformation of the old rural power network, that is, the original 35kV equipment is not moving, and only a 10kV switch box can be installed to meet the requirements of unattended.

5, investment and quick results
Compared with the integrated substation of the same scale (35kV equipment outdoor layout, 10kV equipment in the indoor high voltage switch room and central control room), the investment of European box transformer (35kV equipment outdoor layout, 10kV equipment in the indoor high voltage switch room and central control room) reduces by 40%~50%.

6, Small footprint

Equipment installation:
(1) The box transformer position should be close to the load center. According to the load distribution of the plot, the load moment is calculated to determine the load center. The box transformer is installed near the load center
(2) Strong vibration and impact are not allowed at the use site of box transformer, and large electromagnetic induction intensity is not allowed. For buried lines of box transformer, laying paths of each circuit outlet should be arranged to meet the safe distance to underground facilities, and not affect the long-term development of power supply area;

(3) There shall be no explosive dangerous substances in the place of use, and the surrounding media shall not contain corrosive metals, gases and conductive media that destroy insulation;

(4) The vertical inclination Angle of the box installation shall not exceed 5°, the outdoor wind speed shall not exceed 35m/s, and the relative humidity of the air shall not exceed 90%(25℃);

(5) There is no need to build control room and corresponding workshop for box transformer installation. 10kV equipment has no structure and covers a small area. Only one reinforced concrete foundation can be made according to the box transformer foundation size provided by the manufacturer.
(6) Appropriate lifting equipment shall be selected according to the standard weight and relevant safety regulations, and the included Angle of the lifting rope shall be less than 60°. The rope shall be used to pull the box change diagonally during lifting to ensure its stable position;
(7) The European box transformer has been debugged when leaving the factory, just need to box transformer high voltage and low voltage cable and box transformer connection;
(8) Lightning rods should be set around the box body and the main transformer, and ensure that the equipment is within its safety protection range. The grounding network should be buried before the prefabricated foundation, and the grounding resistance should be less than 4 ω. After the box body is in place, the box body grounding terminal should be firmly connected with it;
(9) Because the European box has reached the technical requirements of unattended, do not set up background equipment, when running, to consider strengthening the anti-theft.

Features of product structure drawing

· The basic structure of the box transformer is divided into "eye" shape and "product" shape. The box frame is made of high-quality channel steel and Angle steel welded with high mechanical strength, and the box is made of woven alloy profiles. With good anticorrosion ability, the overall appearance of beauty can be coordinated with the surrounding environment by painting and coloring. The carefully designed lifting device at the bottom provides great convenience for installation, transportation and movement.

· There are independent high voltage room, transformer room and low voltage room in the transformer room, and the lighting in each room opens automatically when the door is opened. The high pressure room is equipped with high pressure ring switch equipment, which can choose pneumatic/vacuum load switch according to user needs. And has the "five protection" function, when the current limiting type high voltage fuse is used, when a certain phase fuse is broken, the load switch automatically breaks, to avoid the failure caused by the lack of phase operation.

Transformer chamber adopts natural ventilation and automatic control of forced cooling air cooling device, we also varies with temperature and exhaust system of automatic control, control can effectively reduce the temperature in the cabinet, to meet operation requirements, according to user requirements can also adopt the condensation prevention device, according to the requirements of users, is along the track can be conveniently from the pressure chamber between the both sides from the gate in and out. Box material can prevent rain and dirt from entering, with long-term outdoor use conditions, to ensure anti-corrosion waterproof, dustproof performance, long service life, maintenance of single cylinder, beautiful appearance.

· The transformer can be dry type or oil-immersed type. Oil-immersed type transformer can be fully sealed with oil pillow or without oil pillow.

· Low voltage chamber has the overall function of low voltage complete set of switches, for users to choose, arbitrary combination.

· Shell material:

Shell materials are composite plate, stainless steel composite plate, aluminum - zinc plate, stainless steel plate, metal carving board.

· Structure features: high voltage structure is reasonable and compact, SF6, FZN57, VHC ring network cabinet can be selected, all with five interlocking prevention functions.

Transformer natural ventilation and automatic ventilation cooling systems are suitable for dry and oil-immersed transformers.

· Low pressure chamber:

According to the requirements of users, it can adopt a variety of power distribution schemes, power distribution, lighting distribution, reactive power automatic compensation, energy metering and other functions, equipped with automatic lighting system.
