Cleaning of the switching oil by a paper filter

When on-load tap changers are used in industrial transformers under extremelyonlerous conditions (defined as those involving a high switching frequency,consistently at full load and frequent over - loads), arcing will relatively soon causecontamination of the switching oil. This applies, for example, to on-load tap changersincorporated into transformers on furnace or electrolytic plants.

The oil filter unit is used to clean the switching oil in on-load tap changers. Dependingon requirements, it can be fitted with a paper filter for cleaning.

The oil filter unit allows to filter the switching oil continuously without interrupting thetransformer operation.

Filtering the switching oil increases the mechanical life of the diverter switch unitconsiderably and maintains the dielectric strength of heavily stressed insulationmaterial. It also reduces the number of inspections and oil changes which areotherwise necessary at short intervals.

■ The paper filter insert must be replaced when the max operating pressure ofapprox. 3.5bar has been reached. The exact pressure limit is set at the pressuregauge by the manufacturer.

■ Replacement of the paper filter insert should be carried out as follows :

•Shut the stop values of feed and return pipes. •Open the sample valve of the feed pipe and the bleeder screw at the return pipe

elbow oil return at the pressure tank.•Drain about 25 liters of the oil. •Unscrew 12 cover bolts M8/w.s.13 and remove the cover with gaskets. •Unscrew lock nut M12/w.s.19 and remove the filter insert with gaskets.•Install the new filter insert with gasket. Make sure that the gasket is properly

seated. Fasten with lock nut M12/w.s.19, tightening torque 30Nm. •Fasten the cover and the cover gasket (12 screws M18 with nuts, max torque

15Nm.) •Establish connection for the return pipe.•Open the stop valves for feed and return.•Bleed the pressure tank at the return pipe connection.•Bleed the feed pipe connection (suction pipe connection) at the tap changer head. •Repeat bleeding after performation of a test operation.
