Product category: Product Center dry type transformer series product description: green power, safe and reliable, green power, low electromagnetic radiation pollution; The key technical parameters are well balanced to effectively reduce the non characteristic harmonic; Strong overload capacity, reliable operation under VI level load condition. Product details and technical innovations: 1. 24 pulse rectifier, less harmonic; 2. Axial double splitting, eliminating balance reactor; 3. Nomex Paper Insulation System; 4. The single unit can also operate under 12 pulse; 5. Swiss robot fully automatic lamination. Performance features: 45 degree full oblique step joint core adopts imported high-quality grain oriented cold-rolled silicon steel sheet with high magnetic conductivity, 45 degree full oblique step joint adopts special square tube pull plate structure, and the core column is bound with insulating tape; The surface is coated with special resin to prevent moisture and rust, effectively reducing no-load loss, no-load current and core noise. The high-voltage winding conductor of multi-layer segmented cylindrical high-voltage coil is made of F-grade insulated copper wire, reinforced by long and short cut glass fiber felt, and poured with epoxy resin mixture in vacuum (1-3mbar). The partial discharge can be restrained effectively, and the amount of partial discharge is less than 5pc. The low-voltage coil with longitudinal airway foil structure is made of high-quality foil conductor wound on the automatic foil winding machine, with argon arc welding and high welding accuracy; Prepreg DMD is used as interlayer insulation, prepreg glass fiber cloth is used as insulation inside and outside, epoxy resin is used to seal the upper and lower parts, and then it is cured in the curing furnace as a whole; The solid and beautiful protective shell IP20 can prevent the entry of solids larger than 12mm in diameter and resist accidental impact; IP23 not only has the function of IP20, but also can prevent water droplets from flowing into the vertical line within 60 degrees, which is suitable for outdoor installation and use; Customizable. Perfect temperature protection and control device, overheat protection device mainly through the PT thermistor embedded in the low-voltage coil to achieve transformer temperature detection and control. The temperature value of three-phase winding is displayed in circuit during the operation of transformer; Display the temperature value of the hottest phase winding; Temperature alarm trip; Sound and light warning, fan start; Fan overload protection and computer interface.
