Problems solved by technology

In the above-mentioned transformer, although there are heat dissipation oil guide holes on the high-voltage coil skeleton wire groove, due to indirect heat dissipation, it is difficult to dissipate the heat generated by the transformer coil in time, so the heat dissipation effect is not ideal
Since there is no shielding layer between the low-voltage winding and the high-voltage winding, it is impossible to prevent the secondary high voltage from being coupled to the low-voltage winding through distributed capacitance, causing damage to the primary inverter switching circuit
