Preferably, the detector 30 is additionally provided with the display 31 that piezoelectric voltage is climbed in display.30 one end of detector connects metal
Conducting ring 20, other end ground connection, measured voltage climb piezoelectric voltage for 10 surface of insulator, are arranged by detector 30 aobvious
Show that device 31 can be observed directly and climb electric situation, can judge whether also to deposit according to the voltage condition that detector 30 is shown after cleaning
In creepage phenomenon.The display mode of display 31 is either pointer instruction display mode, is also possible to numeric type display mode
Preferably, the master controller 40 is equipped with display screen and alarm.The settable screen display prompt side of master controller 40
Formula or warning note mode climb piezoelectric voltage when detector 30 detects, transmit signals to master controller 40, and master controller 40
It is believed that number making screen display prompt, in order to avoid personnel neglect screen display prompt information, alarm can be set simultaneously, further,
Warning lamp can be set in obvious position.
It is highly preferred that the master controller 40 is additionally provided with function set key.It is settable to climb piezoelectric voltage by function set key
Alarm limits and step-down value, the voltage value of flashover fault should occur lower than insulator for the piezoelectric voltage alarm limits of climbing, when climbing electricity
Voltage then carries out warning note when reaching alarm limits, while master controller will issue buck signal to high piezo controller, separately
One side staff sees that screen display prompt must confirm, and personnel is arranged to carry out dress watch to insulator surface；Work as hair
Out when nobody processing of warning note, master controller 40 will continue to issue prompt information, while carry out further decompression processing,
Decompression processing is depressurized to the 80% of primary voltage value by warning note for the first time, and secondary prompt is then depressurized to 60%, prompts, is depressured three times
It is then directly shut down to 40%, four prompt；Further, when climbing piezoelectric voltage close to insulator breakdown voltage, master controller 40
Then directly issue the instruction for closing power supply.
Preferably, the high-voltage electricity controller 50 connects high voltage power supply, and the closing or voltage for controlling high voltage power supply are adjusted.Institute
State master controller 40 and be connected with high voltage power supply controller 50, the high voltage power supply control device 50 control electric field clarifier shut down and electricity
Pressure is adjusted, and the master controller 40 will test the electric signal that device 30 passes over and be analyzed, and reaches setting when climbing piezoelectric voltage value
Alarm limits when, master controller 40 issues warning note, while transmitting buck signal to high voltage power supply controller 50, high-voltage electricity
Source controller 50 carries out decompression processing according to the instruction received, and with low pressure electricity operation, examination climbs electricity to eliminate, works at the same time personnel couple
10 surface of insulator is checked and is cleared up, wait all go well in the case where restore high-voltage electricity again, while electric situation is climbed in observation
Whether eliminate, then restores to operate normally if eliminating, if detector 30 still shows creepage phenomenon, then close and examine again
It repairs, until electricity is climbed in elimination；If handled after 40 warning note of master controller without personnel, master controller 40 carries out two
Secondary warning note, and secondary decompression is carried out, if still unmanned processing after secondary decompression, then alarmed and be depressured three times, three
Still untreated after secondary decompression, master controller will issue out code, and high-voltage electricity controller closes power supply, caused by because climbing electricity
Harm.
In the actual implementation process, metallic conduction ring 20 snugly fits to 10 top of insulator, 20 outer wall of metallic conduction ring
It contacts with 10 surface maximum area of insulator, and is mounted on fixed frame 11 by insulator 10, when insulator 10 climbs electricity
Phenomenon, 20 energy real-time capture of metallic conduction ring obtain climbing piezoelectric voltage by the detection of detector 30 to charge, and detector 30 will be examined
The voltage signal measured is converted into electric signal, and passes to master controller 40, and master controller 40 is settable to climb piezoelectric voltage alarm limit
Value step-down value and interval alarms, master controller 40 judge electric signal according to the voltage alarm limit value of setting, issue alarm
Prompt and sending decompression processing signal are to high-voltage electricity controller 50, and high-voltage electricity controller 50 carries out decompression processing, and decompression for the first time is
The 80% of primary voltage value climbs electricity by being depressured to eliminate, to guarantee that insulator 10 is not breakdown, works at the same time personnel to insulator 10
Surface carries out inspection cleaning, clean to 10 removing surface of insulator, and elimination restarts power supply when climbing electrical environment again.Work as main control
When device 40 issues nobody processing of warning note, master controller 40 carries out secondary warning note after 30 minutes, is simultaneously emitted by secondary
Buck signal, after voltage is down to the 60% of primary voltage, 30 minutes by secondary decompression, if still unmanned processing, then alarmed three times
Prompt, and third time decompression is carried out, voltage is down to the 40% of primary voltage, if the still unmanned processing of third time warning note, master control
Device processed, which directly issues, closes power supply prompt, and high-voltage electricity controller carries out closing processing, after staff is handled and check it is errorless after
It can start.
It is understood that for those of ordinary skills, can with technical solution according to the present utility model and
