The detection method of a kind of platform district discharge fault detection device based on acoustooptic technique, comprises the steps:
Step one: platform district discharge fault is detected device and is arranged on 0.6～2 meter of above platform district transformator, and make single-chip microcomputer 8 connect with supply unit；
Step 2: the discharge scenario of insulator, crane and transformator in the discharge fault of platform district described in step one detection device real-time detection scaffold tower district to be checked；
Step 3: when one of insulator, crane or transformator produce discharge scenario in the scaffold tower district to be checked described in step 2, UV sensor 4, first it is detected that the ultraviolet data that produces of electric discharge, and transfers data to single-chip microcomputer 8；
Step 4: the single-chip microcomputer 8 in described in step 3 controls the ultrasound data produced when ultrasonic sensor 3 gathers electric discharge immediately after receiving ultraviolet data, and makes this ultrasound data feed back to single-chip microcomputer 8；
Step 5: ultraviolet data described in step 3 and ultrasound data described in step 4 are delivered to data analytics server 2 by transmission antenna 5 by single-chip microcomputer 8 after treatment；
Step 6: the data analytics server 2 in described step 5 by being analyzed to judge the electric discharge grade of insulator, crane and transformator in platform district to ultraviolet data and ultrasound data；When ultraviolet pulse number of times is less than 5 times, when ultrasound wave changes voltage into 1V, electric discharge grade is one-level, it was demonstrated that this district's equipment exists slight discharge scenario, can investigate by emphasis in regular visit；When ultraviolet pulse number of times less than 10 times be more than or equal to 5 times, when ultrasound wave changes voltage into 2V, electric discharge grade is two grades, it was demonstrated that this district's equipment exists a large amount of discharge scenario, need to investigate immediately；When ultraviolet pulse number of times is not less than 10 times, and ultrasound wave changes voltage into 3V, electric discharge grade is three grades, it was demonstrated that it is serious that this district's equipment exists discharge scenario, need to overhaul replacing immediately.
This utility model is for insulator, crane and transformer discharge situation in probe station district；When using this utility model, this utility model is installed on the distance of about 1 meter above platform district transformator, when platform district insulator or transformator are because of fault discharge, UV sensor 4 can detect the ultraviolet data that electric discharge produces, and transfer data to single-chip microcomputer 8, single-chip microcomputer 8 can control ultrasonic sensor 3 immediately, the ultrasound data produced when gathering electric discharge, single-chip microcomputer 8 carries out simple algorithm process after obtaining ultraviolet data and ultrasound data, sent data in data analytics server 2 by transmission antenna 5 by wireless network afterwards, and judge insulator in platform district by data are analyzed to, the discharge scenario of crane and transformator；This utility model can in the discharge scenario in round-the-clock monitoring station district.When long-time 1 little time discharge off data, its geographic location information can be sent to data analytics server 2 by this utility model；Described can be half an hour for a long time, 1 hour or 2 hours etc..
This utility model utilizes the interference that method that UV detection and ultrasound examination combine is brought to the limitation detecting shelf depreciation single method detection can being avoided to bring and environmental factors, can with the generation of light harmony during shelf depreciation, owing to light harmony synchronizes to produce so that light harmony possesses relatively uniform Changing Pattern and characteristic.So can pass through ultrasonic sensor 3 and UV sensor 4 gathers acoustic and light information, according to its concordance, analyze the acoustic and light information collected；Owing to shelf depreciation possesses randomness, and strength of discharge presents dynamic, the interference of metastable for nature ultraviolet can be filtered out according to these characteristics, by using blind type UV sensor 4, it is insensitive to the ultraviolet component in natural light, utilizes this characteristic to filter the interference of nature light.The ultrasonic sensitivity to electric discharge, it is possible to detect discharge information, but owing to the sound wave interference source of extraneous near frequency band is a lot so that the sensitivity of type local-discharge ultrasonic decreases.Ultraviolet detection and ultrasound examination combine and can mutually make up respective deficiency so that the sensitivity detected is strengthened further.Due to the uniqueness that ultraviolet on power equipment and circuit produces so that the accuracy of detection is higher.It addition, this utility model adopts non-electrical detection mode, being not directly contacted with high-tension electricity side, safety is relatively good, has good independence；Adopting ultraviolet light and ultrasound wave comprehensive survey, two kinds of methods complement each other, and capacity of resisting disturbance is significantly larger than the detection method that tradition is single.Particularity due to the monitoring mode of this device so that monitoring cost is substantially reduced, monitor device volume is substantially reduced.This utility model can the insulation of effective monitoring platform district, spark gap self deterioration or due to pollution flashover with wet dodge reason guiding discharge；The electric discharge that platform district inside transformer winding and oil ageing cause；Owing to the reasons such as temperature, humidity, vibrations cause the electric discharge that localized contact is bad and causes between platform district circuit, switch, gold utensil, transformator, insulator.
