High secondary current in electric demisting
Thread Content
Dear experts, for the tailings acid production system, the primary voltage of the electrostatic precipitator is 160V, the secondary voltage is 32KV, the primary current is 20A, and the secondary current is as high as 920mA. What could be the reason for this?
Check whether there is any short circuit in the equipment
Shut down the faulty electrostatic fogging equipment, ground it, and conduct an isolation inspection; it is possible that the corona wire is broken or has fallen off, the negative electric field strength is high, which causes the corona wire to be drawn in, and the quartz tube is damaged by arcs
How many tubes does the electrostatic demister have? The data shows no short circuit; whether the data is reasonable needs to be assessed comprehensively, taking factors such as changes in gas conditions into account.
The secondary current is high while the voltage is normal; the gas is too dirty
