Embodiment one

One kind disclosed in one or more embodiments can pinpoint local discharge detection device, including host 1, ultra-high frequency signal acquisition module, high-frequency current signal acquisition module, AE sensor, ultra-high frequency signal sensor, high-frequency current Signal transducer, the channel Ultra monitoring headpone, USB data line and synchro source wireless trigger device.

Wirelessly connect between host 1 and ultra-high frequency signal acquisition module, between host 1 and high-frequency current signal acquisition module It connects and carries out data transmission, signal connects between ultra-high frequency signal sensor and ultra-high frequency signal acquisition module, high-frequency current letter Signal connects number between sensor and high-frequency current signal acquisition module, is equipped on host 1 and to connect with AE sensor signal LEMO interface 18,1 bottom of host be equipped with for connect the Audio interface 14 of the channel Ultra monitoring headpone, usb 15, with it is outer Power interface 16, the Ant interface 17, USB for being connect with the external antenna of synchro source wireless trigger device for connecing power supply connection Interface 15 is connect by USB data line with computer.

As shown in Figure 1, host 1 has insulation crust, host display 11 and switch 12 are equipped on host 1, wherein leading Machine display screen 11 is touch screen, Ultra sensor built in host 1 and TEV sensor, and Ultra sensor and TEV sensor are through passing Sensor detection mouth 13 is detected, as shown in Fig. 2, having the advantage that Ultra is sensed using Ultra sensor detection sound wave Device is more ear-sensitive than people, and the operation independent of operator is horizontal and on audible frequency range, and has directionality.

As shown in figure 4, LEMO interface 1818 is equipped on the right side of host 1, for connecting with AE sensor.

Ultra-high frequency signal sensor (type UHF sensor): ultra-high frequency signal sensing is placed at the external disk insulator of GIS Device, for detecting the ultra-high frequency signal of its internal shelf depreciation excitation.

High-frequency current signal sensor (HFCT sensor): it when power cable generates shelf depreciation, can generally inspire High-frequency pulse signal and ultrasonic signal.High-frequency pulse signal frequency, can be in the circuit of cable run generally in 300kHz or more High-frequency current signal sensor is directly clamped among on cable grounding line by middle propagation, to detect the pulse issued from shelf depreciation point Signal carries out coupling output, carries out real-time monitoring and analysis using analytical equipment.It is connect since pulse current of PD can flow through Ground wire can therefrom detect high-frequency discharge signal by high-frequency current signal sensor card on the ground line of cable.

AE sensor: when partial discharge phenomenon occurs, intermolecular sharp impacts simultaneously form a kind of pressure in macroscopically moment, Ultrasonic pulse is generated, by being tightly attached to GIS, cable or transformer shell or body surface can receive and propagate along shell Ultrasonic signal of the frequency between 10kHz-200kHz, according to the amplitude, phase, original signal characteristic of the signal received with The comparison of background signal, and the analysis of the correlation properties with power frequency, can carry out fault degree assessment, abort situation analysis and Fault type tentatively identifies.Acoustic method is non-intrusion type and is influenced by external electromagnetic noise smaller, is more satisfactory show Field detecting method.When using AE sensor measurement, since AE sensor cannot be placed directly within cable accessory surface, to prevent from causing Personal safety, it is necessary to come the shelf depreciation of detection cable in such a way that waveguide rod and ultrasonic sensor combine.

TEV sensor built in host 1 and Ultra sensor, the right side of host 1 are equipped with LEMO interface 18, multiplexing AE sensing Device and Ultra sensor.As shown in figure 3, setting in the bottom of host 1, there are four interfaces, are respectively as follows: (1) Audio interface 14, use In connecing the channel Ultra monitoring headpone, the signal that Ultra sensor receives is monitored；(2) usb 15 pass through usb 15 The data that equipment is surveyed are transferred on computer or mobile phone with USB data line；(3) Power interface 16, Power interface 16 with it is external Power supply connection is charged, and is charged using mating charger, and indicator light is red on charger when underfill, full of when be green Color；(4) Ant interface 17, for being connect with the external antenna of synchro source wireless trigger device.

Synchro source wireless trigger device can patch the two hole socket of common wiring board or cable reel, have blue on trigger Indicator light has blue light instruction after energization；When field application, visual actual conditions external antenna.Lithium electricity is additionally provided in host 1 The charging to host 1 is realized by charger in pond.

(1) when the battery icon of host 1, which reddens or is switched on, not to work, user needs to charge to host 1 in time, and uses The charger (12.6V/1A) of this coordinative composition of equipments gives host 1 to charge, and has charging indicator light on charger, is red when underfill, Full of when for green；

(2) when the battery capacity indication lamp of module reddens color, user needs to charge to host 1 in time；And use charger (8.4V/1A) gives module charging, there is charging indicator light on charger, is red when underfill, full of when for green；

(3) when host 1 or module for a long time when not used, should charge every three months to host 1 or module, avoid built-in lithium electricity Pond is because decompression causes to scrap.When host 1 or module are in charged state, partial discharge test please don't be carried out and equipment is allowed to be in shutdown State.

When host 1 is in off-mode, the switch 12 on host 1 is pressed, host display 11 can be shinny immediately, simultaneously " ticking " sound can be issued and show that power supply has already turned on, occur self-test information interface on host display 11 about 3 seconds, at this 3 seconds For interior click screen automatically into touch screen screen calibration function, no touch screen skips mark display main interface automatically.

When host 1 is in open state, the switch 12 on host 1 is pressed, the built-in booting delay function of host 1 (avoids Quick-break speed is opened to internal device damage), user need to can just turn back on after shutdown three seconds.Main menu can be shown after booting Come, there is following icon on main menu:

(1) database TEV&Ultra: into the database set interface of TEV&Ultra, the interface is particular for switch 12 The feature of cabinet measurement carries out data file storage setting；At database TEV&Ultra, user can by new buttons 61 into Row database is newly-built, also selectes current database by the serial number before selection database；

(2) it is arranged: enters and each system parameter mode and display device system information are set；

(3) Ultra is measured: measurement Ultra sensor obtains signal；

(4) Ultra map: Ultra sensor is measured with map mode and obtains signal；

(5) TEV is measured: measurement TEV sensor obtains signal；

(6) TEV map: TEV sensor is measured with map mode and obtains signal.

(7) UHF is measured: measurement type UHF sensor obtains signal；

(8) UHF map: type UHF sensor is measured with map mode and obtains signal；

(9) HFCT is measured: measurement HFCT sensor obtains signal；

(10) HFCT map: HFCT sensor is measured with map mode and obtains signal；

(11) AE is measured: measurement AE sensor obtains signal；

(12) AE map: AE sensor is measured with map mode and obtains signal；

(13) hidden function: when clicking the region Logo in main interface, Logo picture will do it switching, and equipment state also exists Switching in " use " and " connection ", in " connection " state, equipment can directly connect transfer detection data with computer or mobile phone.
