Model meanings

Working conditions of American type prefabricated substation

◆ Altitude not exceeding 1000 meters

◆ Environmental temperature: -35 ℃~+40 ℃:

◆ Relative temperature:, daily average value not exceeding 90%, May average value not exceeding 90%:

◆ Installation location: No fire, explosion hazard, chemical corrosive gas, and well ventilated place, ground inclination angle not exceeding 3 °.

Function features of American type prefabricated substation

◆ Fully insulated, fully sealed, maintenance free, and reliable to ensure personal safety;

◆ Compact structure, with a volume of only 1/3 to 1/5 of the same capacity of European transformers, and low height;

◆ A split box structure can be adopted to avoid oil contamination in the transformer oil tank;

◆ The high-voltage side adopts dual fuse weight range protection, greatly reducing costs;

◆ It can be used for ring networks or terminals, and the cable head can be urgently plugged and unplugged when the load current is 200A; The box adopts a honeycomb double layered composite board, which has the function of temperature insulation and heat dissipation

◆ Install an electronic phase loss protector on the low-voltage side, which can quickly disconnect the main incoming switch when abnormal voltage occurs in the system; High voltage oil immersed load switch or SF6 load switch can be upgraded electrically, laying the foundation for achieving distribution network automation; Use oil immersed S9 or better performing S11 series transformers.

Technical parameters of American type prefabricated substation

Civil engineering drawing of substation cable inlet and outlet

Technical requirements:

◆ For dimensions, please refer to the actual dimensions of the combination variable;

◆ The concrete foundation machine should have a flat surface, and the combined substation should be fixed on the foundation using pressure plates;

◆ The types of grounding bars and cable fixing brackets can be determined according to the actual situation;

◆ Cable fixing brackets and grounding bars should be pre embedded;

◆ The position of cable holes for incoming and outgoing lines depends on the specific situation;

◆ After the installation of the combination transformer, there must be a gap of no less than 1.5m on the front of the switch for easy operation;

◆ The grounding grid can be made of 12 galvanized round steel or 40 × 4 galvanized flat copper, and the grounding resistance should meet the requirements of the power department.
