High Voltage Dc Contactor

China suppliers ICHYTI Low Price high voltage dc contactor is suitable for applications with high DC voltage and high current variations. In recent years, in the fields of photovoltaic, energy storage, wind energy, and electric vehicles, products require vacuum cleaning or filling with nitrogen and inert gas for arc extinguishing. In vacuum, with low pressure, there are fewer gas molecules, and the breakdown voltage between contact gaps increases, thereby reducing the possibility of arc formation and achieving the goal of arc extinguishing. Inflated inert gas decomposes and ionizes at high temperatures, possessing the properties of adsorbing free electrons and forming negative ions. Its arc has a lower arc voltage, smaller arc diameter, and smaller thermal inertia of the arc column. These two sealing technologies require high process capability and cannot damage the airtightness of the product throughout its entire lifespan, otherwise the product's lifespan will be greatly shortened.
