Describe

Yb Portal Series prefabricated substation is a series of products designed and developed by our company to meet the needs of urban network construction. This series of products is a complete set of distribution equipment that combines medium voltage switchgear, transformer and low-voltage distribution equipment according to a certain wiring scheme.

This series of prefabricated substation is applicable to 12kV The three-phase AC system with rated frequency of 50Hz and capacity of 2500kVA and below is suitable for residential quarters, commercial buildings, hotels, large construction sites, high-rise buildings, industrial and mining enterprises and temporary construction sites. It is suitable for ring network power supply and radial terminal power supply.

This series of prefabricated substation has the advantages of compact structure, strong integrity, safe and reliable operation, convenient maintenance, beautiful appearance and so on; It has the characteristics of small volume, small floor area, large selectivity, small on-site installation, short installation and commissioning cycle, and moving with the load center.

Product model and meaning

Normal service conditions

1. The ambient air temperature shall not exceed + 40 ℃, and the minimum ambient air temperature shall be - 25 ℃;

2. The altitude is no more than 1000m. If special ordered transformers and low-voltage components are used, the altitude can reach 3000m;

3. Places where the vertical inclination does not exceed 5 °, without violent vibration and impact;

4. The air humidity shall not be greater than 90% (+ 25 ℃);

5. No conductive dust Gas places without explosion hazard, rotten metal and electrical components;

6. The outdoor wind speed shall not exceed 35m / S0

Product design features

1. The shell shall be designed according to the foreign technology and the actual situation. It has the characteristics of firm, heat insulation and ventilation, good performance, dust prevention, small animal prevention, moisture-proof, beautiful appearance and convenient maintenance. There are many choices of housing materials. Such as: aluminum alloy plate, steel plate, plywood, stainless steel plate, non-metallic materials (glass fiber cement), etc.

2. High voltage side generally adopts load switch or vacuum circuit breaker, and has complete anti misoperation function. If optional: XGN port-12l sulfur hexafluoride ring network cabinet, XGN port-12, hxgn15 and other ring network switchgear, the ° transformer can adopt oil immersed transformer, and the fully sealed transformer can also adopt dry-type transformer.

3. The substation has perfect protection performance and convenient operation. High and low voltage metering can be selected. Automatic no power compensation device can be equipped according to user requirements.

4. the top 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 high-voltage and low-voltage rooms are designed with independent roof, and the transformer room is equipped with anti condensation and automatic temperature control monitoring, heating and cooling devices.

5. Natural ventilation is adopted for the box, and forced ventilation equipment can also be added. A dust-proof device is installed at the position corresponding to the shutter on the outside of the door panel and side plate.
