Product overview:
A Solar Power Equipment Box-type Transformer that integrates 0.27kV 0.315kV 0.69kv voltage of grid-connected photovoltaic inverter into power grid output energy through a boost transformer.
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.
Mainly used for small and medium-sized solar power generation.
Execution standard: IEC61850 series, GB/T17467, etc.
Product advantages：
Leading technology:
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.
