In addition, when thunder arrester equipment normally runs, current in resistance property accounts for circuital 10% 20%. Sending out sheet catabiosis for the thunder arrester occurred, under generally showing as running voltage, obviously increasing occurs in current in resistance property higher harmonic components; If thunder arrester makes moist, then under showing as running voltage, obviously increasing occurs in resistive current first harmonics component. But the impact being subject to the environmental factorss such as such as running voltage size, atmospheric moisture due to lightning arrester live-line test result is relatively big, so not by the I in simple comparison data over the yearsXPAnd IRPDraw the conclusion that thunder arrester makes moist.
Practical novel content
The purpose of this utility model is to provide GIS electrified tester for zinc oxide arrester device, obtains voltage signal by 220 power supplys in maintenance power supply or station and realizes GIS lightning arrester live-line test, and can reduce the error in test.

Accompanying drawing explanation
Fig. 1 is the Facad structure schematic diagram of the utility model GIS electrified tester for zinc oxide arrester device.
Embodiment
The utility model discloses GIS electrified tester for zinc oxide arrester as shown in Figure 1, comprise main frame 1, data transmission system; Wherein main frame 1 comprises reference signal input terminus, current input terminal, reception of wireless signals end, ground terminal, also comprises voltage isolator 2, and voltage isolator 2 comprises reference voltage input terminal, voltage signal output end; Also being provided with phase-detection device 3 in described main frame 1, described phase-detection device 3 connects phase calibrator 4, and described phase-detection device 3 connects 220 power supplys in maintenance power supply or station and obtains voltage signal. Described voltage signal output end is provided with wireless transmitter. Main frame 1 is also connected with induction plate 5. Described induction plate 5 is the rectangular plate of 40cmX50cm.
GIS substation all runs due to equipment in sealed gas chamber, cannot obtain running voltage signal, finally causes cannot carrying out revealing current sample test online. for addressing this problem, we attempt surveying 220V power taking pressure signal from low pressure, and arrange compensating parameter and the phase differential between once and two times carries out automatically compensation to reach and get the same effect of voltage signal, thus obtain revealing online current data. the focusing on of this technology calculated once by fuzzy algorithm and between two times phase differential and carry out automatic makeup and repay, the final voltage signal obtained in running. when using maintenance power supply or 220V voltage of supply to make reference, between maintenance voltage of supply and the voltage of PT bus terminal case, fixed angles difference is at 30 degree or 60 degree, as long as it is poor that this sampling instrument can calibrate this angle automatically, so get maintenance voltage of supply and replace PT secondary voltage to make reference test arrester resistance current. such as measure A phase thunder arrester total current and current in resistance property, voltage signal obtains from maintenance power supply, but the maintenance power supply in substation is converted to by transformer change used, therefore real work does not know to overhaul the actual phase of power supply, assume that maintenance power supply is B phase, so obtain the voltage signal phase place of A phase by compensating 120 degree and obtain corresponding voltage signal data by Fuzzy Calculation, the reference voltage signal data needed for the measurement of A phase thunder arrester can be obtained, by the utility model namely by obtaining voltage signal from maintenance power supply, realize the test of GIS lightning arrester live-line test.
In actual applications, we carry GIS electrified tester for zinc oxide arrester targetedly and carry out rig-site utilization and detection to dissimilar substation.
The north suburb is become by test personnel, the change of Wu state carries out Zinc oxide lightning arrester live-line test test, this test is measured by identical thunder arrester with GIS electrified tester for zinc oxide arrester and conventional electrified tester for zinc oxide arrester, then test data being contrasted, whether the every technical indicator specifying GIS electrified tester for zinc oxide arrester is up to standard. Each electric substation test data is as shown in the table:
Provide the testing data of wherein three substation field tests below:
From the data form above, we can find, makes reference Voltage Technique by the inner 220kV voltage of supply arbitrarily of substation and realizes lightning arrester live-line test, there is a fixing phase shift between reference voltage and bus voltage. This phenomenon is called as power supply phase shift, voltage range this phase shift more high is more big, its reason is often have necessarily delayed through its output voltage phase place of stage transformer, the transformer number of degrees of process is more many, delayed more big, general 110kV only 1 �� of 220kV having about 2 ��, but 500kV may up to more than 5 ��. And can effectively correct this deviation by the phase-detection device in the utility model and phase calibrator.
