TusDC WINDING PRINANGE TESTERNyob rau hauv Wuhan UHV tuaj yeem pab cov neeg ua haujlwm ua haujlwm ntau lub zog ua ntau yam kev sim hluav taws xob ntau dua {}}
Kuv .} npaj
Lub Zog Tawm & Tawm:
Disconnect txhua qhov hluav taws xob (Armature, teb windings, tswj kev ncig) .
Rau cov neeg muaj zog loj, tshem tawm cov armature: luv luv thiab tsis zoo rau hauv av siv ib lub insulated hlau rau {}}.
Cuab Yeej:
Digital multimeter (tsawg tsis taus ntau): siv rau kev ntsuas ntsuas ntsuas (txwv tsis pub) {}}
Micro Ohmeter (lossisSim Piv Tes): Cov cuab yeej pom zoo pom zoo nrog qhov tseeb ntawm 0 . 1 μ μ ω ~ 1 ω, tshem tawm cov cawv ntawm cov hlau tsis kam.
Qhov ntsuas kub infrared: sau qhov ntsuas kub infraring (tsis kam yuav hloov dua siab tshiab rau hauv qhov kub) .
Looj hnab looj tes thiab hnab looj tes .
II {. ntsuas cov kauj ruam
{{0 {}} riam phom winding (rotor)
Nqa cov tuav tus txhuam hniav lossis tshem cov txhuam txhuam kom cais tawm cov rotor Colrcuit Court .
Ntsuas siv cov micro-ohmermeter 4- xaim (kelvin) txoj kev:
Ib qho tig: Qhov chaw ua haujlwm ntawm ob lub sijhawm uas nyob ib sab sib npaug .
Parallel txoj kev: qhov chaw ua haujlwm ntawm cov neeg ua haujlwm nyob rau 180 degrees sib cais .
Zuag qhia tag nrho: Kev ntsuas nruab nrab ntawm qhov zoo thiab tsis zoo txhuam cov chaw (kom ntseeg tau zoo) .
Cov Txheej Txheem Tseem Ceeb: Maj mam tig lub rotor thiab coj ntau yam kev ntsuas ntawm cov haujlwm sib txawv; xam cov nruab nrab .
2. teb winding (stator)
Disconnect sab nraud hlau thiab ntsuas ncaj qha thoob plaws winding terminals .
NCO TSEG: shunt / series teb tsis kam yog siab dua (tens ntawm kω), cais cov kev zam dhau yog qis dua (ob peb .
Iii {. kev txiav txim siab tseem ceeb
Txhua zaus yuav tsum siv 4- xaim (kelvin) txoj kev:
Txuas cais tawm tam sim no thiab voltage ua rau tshem tawm cov kev ua yuam kev tsis kam ua yuam kev (voltage tiv tauj<1cm from the terminal).
Kub kho mob (tooj liab =0.00393}} / degree):
Cov Qauv: R₂₀=rₜ / [1 + 0.00393 ×} {2} {.
Tshem tawm kev cuam tshuam:
Clean terminals for good contact; pause measurement if humidity >80%; Siv lub ntsuas lub ntsuas kev thim rov qab los thim cov thermal emf .
Iv .} txhaum kev kuaj mob
Infinite tsis kam (ol):Qhib winding los yog tawg lead .
Tseem ceeb tsis kam:Tig-rau-tig luv luv lossis rwb thaiv tsev denadation .
Fluctuitating Readings:Cov pob qij txha txias rau ntawm cov neeg ua haujlwm lossis cov pa roj teeb tsim kho .
>± 3% sib txawv ntawm cov ceg sib txawv:Asymmetrical winding lossis zos luv .
V .} kev nyab xeeb
Txheeb xyuas tsis muaj cov voltage voltage ntawm high-voltage motors (siv voltage Schaer); cov twj hauv av hauv av los tiv thaiv cov esd; Ua raws li iec {{{{60034-27 lossis GB / T 1029 tus qauv .
Tswv yim:Tshawb xyuas cov kev sim ua ke nrog kev ntsuam xyuas (500v / 1000}
