The electrostatic precipitator high-voltage isolation switch is used for switching, transferring, and grounding the high-voltage power supply of each electric field of the precipitator. Its types include two point type, three point type, and four point type. The DC high-voltage isolation switch for the electrostatic precipitator is installed between the electrostatic precipitator and the high-voltage rectifier transformer. It is used for switching the high-voltage circuit in a no-load environment. The switches are divided into: single-pole manual (left, right) bipolar manual, four-pole manual, four-point flexible shaft type, and four-point electric type, which can also be customized according to user requirements. It is installed between the high-voltage silicon rectifier and the electrostatic precipitator, and is used for switching, transferring, and grounding the high-voltage circuit of the electrostatic precipitator in a no-load environment. It is suitable for environments with an altitude not higher than 2000 meters, an ambient temperature not higher than ± 50 ℃, not lower than - 40 ℃, and an ambient relative humidity of ≤ 95% (30 ± 2 ℃). The installation environment should be clean, dry, and free of conductive dust, gases containing corrosive metals, and explosive media, and free of severe vibration.
