•  High-voltage switchgear, transformer body and protective fuse are centrally placed in the oil tank. High-voltage/low-voltage pre-installed substation is set up together with low-voltage switchgear and corresponding auxiliary equipment.

•  Ó jẹ́ ọ̀kan tí ó máa ń lò fún solar power generation kekere ati ọ̀dọ̀.

•  Execution standard: IEC61850 series, GB/T17467, etc.

Ètò ìṣẹ̀:

Technology tó dára:

•  Standard anti-corrosion and salt spray environmental plan to meet the stringent environmental requirements of the site.

•  Compact structure, small footprint, easy installation.

•  Fully enclosed, fully insulated structure, safe and reliable operation.

•  Easy to operate, maintenance-free, low equipment cost.

Enclosure:

•  Adopt cold rolled high quality hot dip galvanized sheet.

•  The surface is treated by electrostatic spray, and the paint can not be taken off for 50 years.

•  Laser numerical control equipment cutting, drilling, bending, to ensure the processing accuracy.

•  Product structure is divided into three parts: high voltage chamber, low voltage chamber and transformer.

•  The cabinet is mainly pre-installed with: lightning arrester, load switch, transformer tap switch, protection fuse, oil level thermometer, oil level gauge, pressure relief valve, amount of oil discharge valve and other accessories.

•  The low-voltage side is equipped with main circuit breaker, overvoltage protector, and can be designed and installed in complete sets of automatic measurement and intelligent control system.

•  The transformer is a low loss oil-immersed transformer produced by WONE You Electric.

Functional units:

•  Fully sealed structure, using the transformer insulating oil as the insulating medium and heat dissipation medium, overall has the advantages of compact structure, good heat dissipation performance.

•  The high-voltage indoor door should be equipped with electromagnetic lock and live display. When the high-voltage side is live, the high-voltage chamber door cannot be opened.

• The external door of the box transformer should be equipped with mechanical lock to meet the five requirements of high-pressure products and ensure personal safety.

 Components:

•  Choose high-quality brand components such as Chint, Shanghai People Electric, Changshu Electric, etc.

•  Schneider, ABB high-quality partners.

Supplementary material：

•  High quality tin - plated busbar copper bar, with insulation sleeve.

•  Hanhe cable is selected for secondary wiring.

 Processing and assembly：

• Assembly workers have been trained for at least 6 months.

• Secondary wiring is fully automatic equipment cutting to ensure reliable wiring.

• Use power tools to ensure proper torque for bolting reinforcement.

• The copper wire bus is NC punched and bent.

• All kinds of experimental tests before leaving the factory to ensure normal operation.
