Zvinotsanangurwa zveiyi Multifunction Partial Discharge Tester
● Edza nzira: 4 nzira dziri dzoga
● Sample's capacity range: 6pF ~250 μ F
● Sensitivity: 0.1 pC
● Kururama: 12 bit
● Sampling rate: 20 M/S
● Ratidza maitiro:
a) Ratidza: Ellipse-sine-yakatwasuka mutsara
b) Trigger synchronization nzira: mukati: 50Hz, kunze: 50 ~ 400Hz
c) Chiratidzo chechikamu chechiratidzo: ellipse kuratidzwa iri mu polar coordinate mode, sine inoratidzwa mune sine wave modhi, panotangira girafu yekuratidzira ndiyo zero point yemagetsi ekuyedza, uye kureba kwegirafu yekuratidzira kutenderera kumwe chete. bvunzo simba rekupa. Iyo sisitimu ndeyechokwadi uye yakarurama mune yekunze inokonzeresa synchronization modhi Inoratidza kutenderera uye chikamu cheyedzo magetsi ekupa.
d) Hwindo renguva: Saizi yechikamu inogona kusarudzwa zvisina tsarukano, uye hwindo renguva rinogona kukwidziridzwa zvine simba uye kuratidzwa. Mahwindo maviri enguva anogona kuvhurwa zvakasiyana kana panguva imwe chete.
e) Kusefa frequency band: 3dB yakaderera-frequency kupera frequency L yakakamurwa kuita gumi, 20, 40kHz magiya, 3dB yakakwira-frequency end frequency fH yakakamurwa kuita 80, 200, 300kHz magiya, uye isu tinogona kuchinjika kunyora akasiyana mafirita passbands.
Signal amplifier
a) Gadzirisa kugadzirisa: Wana kurongeka kwakashata uye uwane kugadziridzwa kwakanaka, kukwenenzvera kugadziridzwa kunokamurwa kuita 5 magiya, iyo mutsauko pakati pegiya ndeye 20dB (10 nguva), iko kukanganisa kunogadziriswa ne ± 1dB; iyo kuwana yakanaka-tuning renji> 20dB
b) Iyo asymmetry yeamplifier yakanaka uye yakaipa polarity mhinduro: <1dB.
c) Chiyero chechiratidzo chekuburitsa chikamu: Chiratidzo chekuburitsa chikamu chinogona kuyerwa mukuenderera, kukwidziridzwa uye mamwe maitiro ekuratidzira nekukanganisa kwe ± 5% (muchiyero chakazara).
d) Chengetedza uye yekutamba mabasa, kudhinda basa, uye kugadzira yakajairika test report
e) Kushanda tembiricha: -10 ~ 45 ℃
f) Hukama Humidity: ≤ 95%, isina-condensing
g) Simba rekushandisa: AC 220V, 50Hz
h) Simba: 300 W
Chimiro cheChishandiso chekuyedza
1.Hapana chikonzero chekusangana nehupenyu chikamu che switchgear, yakachengeteka uye nekukurumidza bvunzo.
2.No vanoda simba kudzima panguva bvunzo maitiro, hapana kudiwa HV bvunzo magetsi.
3.Effectively ziva switchgear kunyange pasi pekuedzwa kumwe, uye kuvaka dhatabhesi yemamiriro ayo
4.Ne ultrasonic test function, zvakare inogona kushandiswa pachikamu chekubuda bvunzo yeSF6 ring main unit uye tambo.
5.Built-in ultrasonic uye TEV sensor.
6.Embedded neine hungwaru yekushandisa system, iri nyore kushandisa.
