HM306 Zinc Oxide Arrester Resistive Tam sim no Tester Wiring thiab Teem Parameter Video
Product Overview & Application Scenarios
HM306 Zinc Oxide Surge Arrester Resistive Current Tester yog ib qho cuab yeej tshwj xeeb uas tsim los ntsuas cov hluav taws xob ua haujlwm ntawm zinc oxide surge arresters. Cov cuab yeej no tsim nyog rau kev sim zinc oxide surge arresters ntawm ntau theem voltage, txawm tias lub zog los yog de-energized, ua kom lub sij hawm tshawb pom cov teeb meem tsis zoo xws li cov rwb thaiv tsev hauv cov dej noo ingress thiab disc aging.
vaj huam sib luag Description
1. Vaj Huam Sib Luag Paub meej
Daim duab 1
Main Unit:Tau txais PT theem nrab-sab voltage lossis Theem B induction phaj hluav taws xob lub zog hluav taws xob (yeem), muab ob txoj kev tau txais hluav taws xob.
Tam sim no nrhiav tau los ntawm lub ntsiab chav tsev yog ua los ntawm kev ua piv txwv nyob rau hauv lub txee terminals los yog los ntawm sampling tus ntes grounding hlau siv tam sim no clamps (yeem), muab ob txoj kev tau txais tam sim no. Cov ntaub ntawv yam ntxwv ntawm zinc oxide ntes tau los ntawm FFT suav.
Synchronization Method:Tus tswv tsev synchronizes ntawm wired synchronization (nrog voltage). Xwb, ib qho hluav taws xob - txoj kev pub dawb tuaj yeem siv los simulate voltage ntawm software, tshem tawm qhov xav tau ntawm qhov hluav taws xob teeb liab txuas.
2. Kev xeem Lead Connection Method
(1) Txoj Kev Ib: Nyob -Txoj Kev Sib Txuas (Tam sim no piv txwv ntawm ob qho kawg ntawm qhov tam sim no transformer, voltage sampling los ntawm ob sab ntawm lub voltage PT, los yog sampling los ntawm lub txij nkawm lub hwj chim davhlau ya nyob twg lub thawv voltage (txog rau lub busbar))
Daim duab 2
Txoj kev kuaj kev sib txuas ntawm cov hlau lead yog qhia hauv daim duab 2. Ua ntej txuas lub ntsiab chav tsev tam sim no cov hlau lead (ob lub xov hlau rub los ntawm 4-pin aviation connector), ntsaws rau hauv lub ntsiab chav tsev aviation connector, ces txuas cov hlau dub mus rau hauv av qis ntawm lub txee. Tom ntej no, txuas cov xaim liab mus rau lub davhlau ya nyob twg qis ntawm qhov ntsuas theem surge arrester thiab lub davhlau ya nyob twg sab sauv ntawm lub txee.
(A) PT Secondary Measurement Terminal Connection Method: Tom ntej no, txuas tus tswv tsev voltage xov hlau (ob lub xov hlau los ntawm 5-pin aviation connector) mus rau aviation connector. Tom qab ntawd txuas cov PT thib ob ntsuas cov davhlau ya nyob twg, txuas cov xov hlau liab thiab dub rau cov theem sib txuas ntawm cov ntsuas ntsuas thib ob. Ua tib zoo ceev faj thaum xaim hluav taws xob tiv thaiv luv luv hauv PT thib ob lossis qhov ntsuas hluav taws xob.
Software Settings:
Tam sim no Clamp: Xaiv "Tsis yog".
Synchronization Method:Xaiv "Wired Synchronization" (nrog voltage). Rau hom voltage, xaiv "Peb-Phase Voltage".
PT Ratio: Tawm tswv yim raws li PT's voltage piv. Feem ntau: 35kV voltage theem=350, 220kV voltage theem=2200, 500kV voltage theem=5000, thiab lwm yam.
Anti- cuam tshuam: Xaiv "Tsis yog".
(B) Txuas rau Maintenance Power Terminal Box: Txuas cov voltage coj los ntawm lub ntsiab chav tsev (2 xov hlau los ntawm 5-pin aviation connector). Ntxig rau hauv lub aviation connector, ces txuas mus rau lub tu lub hwj chim davhlau ya nyob twg lub thawv. Txuas cov xov hlau liab thiab dub rau theem B voltage feem. Ua tib zoo ceev faj thaum xaim hluav taws xob tiv thaiv luv luv.
Software Settings:
Tam sim no Clamp: Xaiv "Tsis yog".
Txoj kev synchronization: Xaiv "Wired Synchronization" (nrog voltage). Rau txoj kev voltage, xaiv "Maintenance Power Supply".
Qib voltage: Tawm tswv yim raws li qib voltage. Feem ntau, 35kV sib raug rau 35, 220kV rau 220, 500kV rau 500, thiab lwm yam.
Anti- cuam tshuam: Xaiv "Tsis yog".
