(4) close before angle valve and back angle valve, circulating fan and heater and whole evacuation system are isolated, utilize vacuum pump to vacuumize to the said air of getting back in the closed container then, be low vacuum at this moment;
(5) once more closed container is vacuumized, be high vacuum this moment;
(6) said closed container is vacuumized simultaneously again and cool off;
(7) after cooling finishes, capacitor is carried out oiling;
(8) at last capacitor is flooded.
With prior art mutually this, there is following technique effect in the present invention:
The first, the present invention opens preceding angle valve, back angle valve and main line angle valve successively after the container heating is opened; Impel the pipeline in the whole system unimpeded, open condenser, blower fan and heater then, flow in the condenser through the air that heated; Airborne oil, steam flow to after the condensation in condenser in the water collector, and the air through condenser is sent in the heater and heats, and gets back in the container from container bottom through 4 arms at last; These 4 arms are arranged on the place, 4 angles of container bottom; The air that from heater, comes out can be evenly distributed in the container, make the gas temperature in the container reach balanced, improve the efficiency of heating surface.
Second; After the container heating is opened; Airborne oil and steam condense into liquid through condenser and flow in the water collector and then outside the amount discharge container in capacitor and the container, thereby reach preliminary removal capacitor internal moisture, alleviate the vacuum pump load, prevent that Residual oil in the container from polluting the purpose of capacitor packet.
