Product overview of 380V dry type isolation transformer
Sg-p (dg-p) series products are imported high-quality cold-rolled silicon steel sheets, with reasonable structure, high reliability, anti-interference, good safety performance, high efficiency and low noise. They are used for UPS bypass, removal of zero ground voltage, high requirements for pure sine wave power supply voltage of imported equipment, etc.
The transformer adopts three column iron core, Y / Y0 or △ / Y0 connection, good insulation between the primary and secondary coils, and double shielding isolation is adopted (shielding further eliminates the high-frequency pulse interference and noise coupled inside the transformer, but although the shielded isolation transformer can effectively prevent various N-G interference (pulse and high-frequency noise), the transformer must be properly grounded). The auxiliary circuit is protected from the interference of power grid and external high-frequency electromagnetic wave and safe manual operation. The device body is installed in the protective net cover to ensure safe and good heat dissipation.
