<p>PROBLEM TO BE SOLVED: To provide a method of preventing breakage of an insulator by preventing the dust and mist from entering in the insulator box, and by preventing the oil of the oil seal from sticking to the insulator. SOLUTION: In the breakage preventing method of an insulator that supports the bus bar 1 for feeding electricity to the discharge electrode of an electric dust collector, an insulating material 11 is filled in the gap between the bus bar and the insulator, and hot air is blown to the outer face of the insulator. And it is desirable that, after the hot air is blown to the insulator through the air blower tube 9, the hot air is exhausted from the air exhaust tube 10 at the upper part of the hot air blowing position.</p> |
