Abstract
The invention discloses a kind of ultraviolet light transducer pulse power supply method, the first voltage and the second voltage alternately and repeatedly, first voltage 300 ~ 350V, duration 50 ~ 500ms；Second voltage 0 ~ 24V, duration 500 ~ 950ms.Through substantial amounts of experimental verification, during normal working voltage minimum duration 50ms per second, it still can reach early warning effect.Compared with prior art, the present invention uses the method for pulse power supply, in the case of the forewarning function not affecting ultraviolet light transducer, improves service life.
Description
Technical field
The present invention relates to a kind of ultraviolet light transducer pulse power supply method, belong to fire-fighting sensor field.
Background technology
Ultraviolet light transducer is the sensor of the C-V characteristic utilizing C-V characteristic photovoltaic detector that ultraviolet signal is converted to signal of telecommunication photovoltaic detector by light-sensitive element.
Ultraviolet light transducer has very important effect in terms of fire alarm.The common running voltage of ultraviolet light transducer is 325 ± 25V, service life 10000h, service life is shorter.
Through retrieval, do not find that document records and use the method for pulse power supply to improve the service life of ultraviolet light transducer.
Summary of the invention
For the problems of the prior art, the invention aims to provide a kind of ultraviolet light transducer pulse power supply method.
In order to achieve the above object, the technical scheme is that a kind of ultraviolet light transducer pulse power supply method, the first voltage and the second voltage alternately and repeatedly, first voltage 300 ~ 350V, energization period at least 50ms per second；Second voltage is no-voltage or low-voltage.
Further, first voltage 300 ~ 350V, energization period 50 ~ 500ms per second；Second voltage 0 ~ 24V, energization period 500 ~ 950ms per second.
Further, described first voltage is 325V, time a length of 50ms；Second voltage position 10V, duration 950m.
Through substantial amounts of experimental verification, during normal working voltage minimum duration 50ms per second, it still can reach early warning effect.
Compared with prior art, the present invention uses the method for pulse power supply, in the case of the forewarning function not affecting ultraviolet light transducer, improves service life.
