Power switch:It adopts mechanical electrical double chain protection,Website: , 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 many quenching load  (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 500HZ—200KHZ.
