The DC switch is mainly used for the disconnection and connection of the DC circuit device. The current DC side voltage of the new energy market such as solar photovoltaic power generation and wind power generation is upgraded from the original DC1000V to DC1500V. The same DC line needs maintenance. For personal and property safety, a switch that can open and close the circuit when the DC voltage is loaded with DC1500V is needed. For this, Linbai Electric successfully developed a 1500VDC switch for two years, which is widely used in solar photovoltaic DC combiner boxes , DC power distribution cabinet, currently leading in China
