Product details

The YB27-12/0.4 high-voltage/low-voltage prefabricated substation (American style) produced by our company is developed by absorbing foreign technology and combining it with the actual situation in China. The entire product has the characteristics of small size, easy installation and maintenance, low noise, low loss, anti-theft, strong overload capacity, and full protection. Suitable for new residential areas, green belts, parks, stations, hotels, construction sites, airports, and other places.

YB27-12 series American prefabricated box type substation is suitable for 10kV ring network power supply, dual power supply or terminal power supply system, as a substation, metering, compensation control and protection device.

1. Altitude not exceeding 1000m;

2. Environmental temperature: -35 ℃ -+40 ℃;

3. Relative humidity: daily average not exceeding 95%, monthly average not exceeding 90%;

4. Installation location: A place without fire, explosion hazards, chemical corrosive gases, and good ventilation, with a ground inclination angle of no more than 3 °.

YB27-12/0.4 high/low voltage prefabricated substation (American style) model meaning

Technical parameter table of transformer:

The S9 series transformer body is selected, with low loss, good overload capacity, strong short-circuit resistance, and all fasteners have undergone anti loosening treatment, eliminating the need for hanging cores; S10 series and S11 series transformers with better performance can also be selected;

Technical parameter table of load switch:

The load switch is oil immersed, three-phase linkage switch, and spring operated mechanism; It can be operated with load, and its opening and closing speed is independent of the magnitude of the operating force. There are two station, four station T-shaped, four station V-shaped and other types to choose from;

Technical parameters of fuses (recommended configuration table for our company's oil immersed fuses):

The high-voltage side of the American box type transformer is provided with full range protection by connecting backup protection fuses and plug-in fuses in series, with a simple principle and economic reliability; The backup protection fuse is an oil immersed high-voltage current limiting fuse with a large breaking capacity, which only operates when there is an internal fault in the transformer. The plug-in fuse is equipped with a dual sensitive fuse, which can provide dual protection for current and temperature. After the dual sensitive fuse is blown, the fuse core can be easily replaced on site.
