Abstract

PURPOSE: To exchange a filter without lowerig the filtering efficiency even during the running of a device to be cooled, by sounding an alarm responding to the increase of press, difference between the inside and outside of said device and simultaneously closing a filtering part by a damper.
CONSTITUTION: Cooling air necessary for collector rings 2 of an generator 1 and an energizing apparatus 3 is sucked through a filter 4 or 5 and is discharged from an air discharging port 6 aftr cooling. The draft is obtained by a cooling fan 7 attached to the apparatus 3. A clogging of the filter 4 generates as the running time elapses; when the press. difference is attained a required level of the filter exchanging, an alarm is sounded by the action of a differential pressure switch 8, and a damper 10 is automatically switched through a driving device 11. An air path at the side of the filter 4 is closed by switching the damper 10, and other filter 5 is used. Accordingly, the exchanging of the filter 4 is performed without lowering the filtering function.
