The Importance of UV Sterilizer Germicidal Lamp and Ballast Matching

The importance of UV sterilizer germicidal lamp and ballast matching Ultraviolet sterilizer is a general term for new ultraviolet water disinfection and sterilization equipment. According to the shape and structure, it is divided into open channel type ultraviolet sterilizer and pipeline type ultraviolet sterilizer. The basic composition of the ultraviolet sterilizer is the ultraviolet germicidal lamp tube and the power distribution system, and the most important part of the power distribution system is the ballast. So it can be said that the ultraviolet sterilizer is composed of ultraviolet germicidal lamp tube and ballast.

According to the disinfection specification for ultraviolet sterilizers promulgated by the Ministry of Health, when the power supply voltage is 220V, the intensity of ultraviolet radiation with a wavelength of 253.7nm must not be lower than 70μW/cm2, and the level of ultraviolet intensity directly affects the effect of disinfection. The intensity of ultraviolet rays depends on the matching of ultraviolet germicidal lamps and ballasts. At present, the ballasts of ultraviolet sterilizers mostly use electronic ballasts.

Electronic ballasts have the advantages of energy saving, low-voltage start-up, and high power factor. They have become the replacement product for ultraviolet germicidal lamps and are basically used in ultraviolet germicidal lamps. Good quality and high power factor. When the same ultraviolet germicidal lamp is replaced with an electronic ballast, the power consumption can be reduced by more than 25%, while the radiation intensity can be increased by more than 12%, and the service life of the lamp is greatly extended. Especially for some ultraviolet germicidal lamps that use magnetic ballasts and the radiation intensity cannot meet the disinfection requirements, as long as the radiation intensity is above 60μW/cm2, the use requirements can basically be met when replaced with electronic ballasts.

Electronic ballasts do not have high requirements for the power supply voltage of the ultraviolet sterilizer. As long as the power supply voltage is higher than 180V, the minimum standard radiation intensity of 70μW/cm2 can be achieved. The ultraviolet sterilizer replaces the traditional magnetic ballast with an electronic ballast. Although the one-time investment is relatively high, its potential economic benefits are very considerable in the long run. Of course, the premise of realizing the above functions is that the ultraviolet germicidal lamp and the ballast must match.

When the electronic ballast of the ultraviolet sterilizer is more powerful than the ultraviolet germicidal lamp tube, the ultraviolet germicidal lamp tube is easy to ignite, but the ultraviolet germicidal lamp tube is easy to age and shorten its life. Because the inductance of the electronic ballast is too small and the current passing through it is too large, the voltage at both ends of the ultraviolet germicidal lamp is too high, and the life of the filament is reduced. When the power of the electronic ballast is too small than that of the ultraviolet germicidal lamp, it is difficult to ignite or cannot be ignited.

Because the inductive reactance of the ballast is too large and the passing current is too small, the voltage at both ends of the ultraviolet germicidal lamp tube is too low, and the filament cannot be ignited. Therefore, the electronic ballast is more powerful than the ultraviolet germicidal lamp tube, and the lamp tube withstands too much current, and the life of the ultraviolet germicidal lamp tube is reduced.
