Description

technical field

[0001] The invention relates to the field of power supplies, in particular to a drive power supply for electrostatic oil fume purification. Background technique

[0002] The electric field of the electrostatic oil fume purifier uses a cylindrical honeycomb structure, so that the electrostatic field can evenly reach the maximum average electric field strength, greatly increasing the area of ​​electric field purification, and making the electric field and oil fume particles combine for a longer time, thus determining The equipment has extremely high oil fume removal efficiency. The sampling method adopted by the detection circuit in the electrostatic oil fume purification driving power supply is to add a current limiting circuit before the high voltage package, which can only protect against overcurrent, but cannot automatically match various electrostatic fields and automatic gear switching, and cannot detect open circuit, short circuit, Overvoltage and fire ...
