When the primary and secondary currents of the wet electrostatic precipitator reach the rated value, the primary voltage is 280~330V, and the secondary voltage is 40 ~ 50kV, without flashover. What's going on here?

The cause of this phenomenon may be serious leakage of the high-voltage cable and the terminal head.

Handling: Redo high voltage cable with terminal head.

The secondary voltage of the 1. is low, the secondary current is small, and the primary current is very large. When the secondary current rises, the 1. secondary current is out of proportion. The primary current increases sharply and suddenly, which may explode and melt quickly, and the transformer has obvious abnormal sound. How to solve this situation?

This situation may be caused by the short-circuit fault of the low-voltage package of the rectifier transformer or the insulation damage of the core of the rectifier transformer (including the core bolt) and the serious eddy current.

Treatment:(1) Replace the low-voltage package;(2) Re-insulate the iron core.

If the primary voltage and secondary voltage are low, the secondary current is too small. The primary current is much larger and rises fast, which is out of proportion to the rise of the secondary current. How to deal with such a situation?

This situation may be the rectifier transformer has a turn-to-turn short circuit or the silicon stack has the existence of open circuit or breakdown short circuit.

Treatment: do open circuit test, there is a current on the primary side, that is, there is device damage inside the transformer, partial excitation or short circuit. It is necessary to repair the hanging core and replace the damaged device.

If the use of circulating water volume gradually decreased, dust removal efficiency gradually decreased the phenomenon of how to deal with it?

Pipeline and circulating water pump fouling may be the cause of this phenomenon.

Treatment: appropriately reduce the PH value of the circulating water tank to 5.2 operation.
