ABNORMALITY DETECTOR FOR OZONIZER

摘要

PROBLEM TO BE SOLVED: To secure the stabilized supply of ozone and to improve reliability and safety by dispensing with an expensive ozone detector to reduce cost and securely detecting water incorporation abnormality of water content. SOLUTION: An current detecting part 5 for detecting current Ip flowing in a power line 4 of a high voltage generating circuit 3 in an ozone generating part 2 and an abnormality judging part 6 for outputting an abnormality signal Sa if the detected value of the current Ip detected by the current detecting part 5 becomes lower than a reference value previously determined by the relation between the water content in a raw material for ozone generation and the current Ip are provided and the water incorporation abnormality that water is contained in the raw material for ozone generation is detected.
