APPARATUS FOR MEASURING CONTAMINATION LEVEL OF INSULATOR CERAMICS

摘要

PURPOSE:To measure the contamination level of insulator ceramics simply and quickly on job site by force-moisturizing an insulator to be measured with an artificial mist by means of a humidifier to indicate the contamination level of the surface thereof in terms of attachment value of equivalent salt. CONSTITUTION:An insulator 2 to be measured is housed in a capsule 1 and semi-cylindrical shell pieces 3 and 4 are closed so as to put an electrode 7 tightly thereon 2. A high frequency voltage is applied to an ultrasonic vibrator 10 of a humidifier 8 to atomize water and mist thus generated is injected into a capsule 1 through a blow-off port 9 with a fan 12 to moisturize the surface of the insulator 2 being measured amply. With the application of a fixed voltage between electrodes 7 and 7, current flowing is read out with a display section 13 to obtain the attachment value of equivalent salt.
