Disturbed caused by limitation and environmental factor caused by method detection, during shelf depreciation can with the generation of light harmony, by
Synchronously produced in light harmony so that light harmony possesses relatively uniform changing rule and characteristic.Supersonic sensing can so be passed through
Device 3 and UV sensor 4 gather acoustic and light information, according to its consistency, analyze the acoustic and light information collected；Due to shelf depreciation
Possess randomness, and strength of discharge presentation is dynamic, can nature is metastable ultraviolet dry according to these characteristics
Disturb and filter out, by using blind type UV sensor 4, it is insensitive to the ultraviolet component in natural light, utilizes this spy
Property filters out the interference of natural light.The ultrasonic sensitiveness to electric discharge, discharge information can be detected, but due to the close frequency in the external world
The sound wave interference source of section is a lot so that the sensitivity of type local-discharge ultrasonic decreases.Ultraviolet detection and ultrasound examination combine can be with
Mutually make up respective deficiency so that the sensitivity detected is further strengthened.Due to ultraviolet generation on power equipment and circuit
Uniqueness so that the degree of accuracy of detection is higher.In addition, the present invention uses non-electrical detection mode, high-tension electricity side is not directly contacted with,
Security is relatively good, has good independence；Using ultraviolet light and ultrasonic wave comprehensive survey, two methods complement each other, and resist
Interference performance is significantly larger than the single detection method of tradition.Due to the particularity of the monitoring mode of the device so that monitoring cost
Substantially reduce, monitoring device volume is substantially reduced.The present invention can effective monitoring taiwan area insulation, arrester self deterioration or due to
Pollution flashover and wet sudden strain of a muscle reason guiding discharge；Discharged caused by taiwan area inside transformer winding and oil ageing；Taiwan area circuit, open
Because the reasons such as temperature, humidity, vibrations cause to put caused by localized contact is bad between pass, gold utensil, transformer, insulator
Electricity.
