The power switch adopts mechanical electrical double
chain protection, which completely avoids equipment damage caused by inverter
open circuit due to gas off and power failure, and can achieve the power
allocation of one power supply to induction heating load (induction
heating transformers). The conductive components are made of high-quality
copper, which overcomes burning and heating of traditional contactor contact,
and completely achieves safe and reliable high-power switching. The switcher
adopts water cooling mode, which can realize large current on-off for a long
time without heating, and it is divided into one to two, one to three, one to
four, etc., with a power range of 50-2000 kW, and frequency of 500 HZ—200kHZ.
