Qhov Primary Current Injector Tester yog dab tsi?
CovPrimary Current Injector Testeryog qhov tshwj xeeb siab-tam sim no, qis-voltage test set tsim los txhaj tshuaj AC tam sim no ncaj qha rau hauvthawj sabntawm hluav taws xob apparatus. Tsis zoo li kev txhaj tshuaj thib ob teeb tsa uas simulate cov teeb liab rau relays, thawj qhov kev txhaj tshuaj tiv thaiv qhov ntsuastag nrho txoj kev tam sim no, nrog rau tam sim no transformers (CTs), thaiv, kev sib txuas, thiab cov thawj conductors ntawm Circuit Court breakers lossis busbars.
Qhov system no yog qhov tseem ceeb rau kev txheeb xyuas qhov tseebkev ua haujlwm tiag tiagntawm kev tiv thaiv. Nws lees paub tias CTs raug xaim kom raug, muaj qhov tseeb qhov sib piv thiab polarity, thiab tag nrho cov saw hlau tiv thaiv - los ntawm thawj tus neeg xyuas pib mus rau relay - ua haujlwm raws li xav tau raws li qhov tseeb load lossis txhaum tam sim no.
Peb cov tshuab muaj xws li los ntawm cov chav nyob portable (500A-1000A) rau qhov chaw tu mus rau siab -chaw nres tsheb-chav kawm units (2000A-50000A) rau substation commissioning thiab Hoobkas kuaj. Lawv yog cov cuab yeej indispensable rautransformer commissioning, kev ntsuam xyuas switchgear, thiabtiv thaiv relay pov thawj

Daim ntawv thov Scenario
Kev Ntsuas Cov Khoom Siv Hluav Taws Xob thiab Kev Kho: tuaj yeem siv rau kev tshaj tawm, kub nce, thiab tiv thaiv qhov ntsuas hluav taws xob ntawm cov khoom siv hluav taws xob xws li cov hluav taws xob hluav taws xob, cov contactors, thiab cov relays, nrog rau tam sim no - nqa lub peev xwm thiab kev ntsuas hluav taws xob ntawm cov cables thiab busbars.
Kev Tshawb Fawb Cov Khoom Siv thiab Kev Ua Haujlwm: tuaj yeem siv los ntsuas cov hluav taws xob conductivity ntawm cov ntaub ntawv thiab tuaj yeem ua tiav cov hlau yaj thiab vuam los ntawm electrothermal cua sov.
Kev Tshawb Fawb thiab Kev Qhia: Simulates cov kev ua haujlwm tiag tiag hauv kev tshawb fawb xws li hluav taws xob hluav taws xob thiab kev xa hluav taws xob. Kuj tseem siv tau rau kev qhia ua qauv qhia thiab kev sim ua haujlwm hauv hluav taws xob engineering cov haujlwm hauv tsev kawm qib siab.
Cov ntsiab lus dab tsi yuav tsum nco ntsoov thaum siv?
1. Kev ceeb toom txog kev nyab xeeb (tseem ceeb)
** Kev txwv nruj nruj rau qhov qhib -Circuiting the CT Secondary side:** Qhov no yog txoj cai kev nyab xeeb tseem ceeb tshaj plaws. Thaum txhaj tam sim no rau hauv CT thawj sab, CT thib ob sab * yuav tsum * muaj kev ntseeg siab luv luv -circuited lossis txuas nrog lub nra. Nws yog txwv tsis pub qhib CT thib ob Circuit Court thaum muaj zog; ua li ntawd yuav ua kom muaj hluav taws xob siab heev (muaj peev xwm ntau txhiab volts), ua rau muaj kev phom sij rau cov neeg ua haujlwm kev nyab xeeb thiab cov khoom siv rwb thaiv tsev.
**Risk of High-Tam sim no Burns:** Cov zis tam sim no loj heev (xws li ntau pua mus rau txhiab tus amperes), ua rau cov kev xeem coj mus kuaj thiab tus neeg xyuas pib nyob rau hauv qhov kev xeem kom sov heev. Tsis txhob kov qhov kev sim clamps, tus neeg xyuas pib nyob rau hauv kev sim, los yog cov hlua hluav taws xob los tiv thaiv kev kub nyhiab heev.
** Strong Magnetic Field Interference:** High tam sim no tsim muaj zog magnetic teb; qhov chaw xeem yuav tsum tau khaws cia ntawm qhov chaw nyab xeeb ntawm cov cuab yeej precision, cov khoom siv sib nqus, thiab cov tib neeg hnav cov tshuab pacemakers.
2. Kev siv hluav taws xob thiab kev ua haujlwm
**Test Lead Selection:** Koj *yuav tsum* siv cov kev xeem coj mus kuaj uas muaj tus ntoo khaub lig loj txaus -sectional area. Kev siv cov hlau lead uas tsis muaj txoj kab uas hla tsis txaus yuav ua rau muaj hluav taws xob ntau dhau ntawm txoj kab, tiv thaiv lub cuab yeej los ntawm kev tso tawm nws cov ntsuas tam sim no thiab ua rau muaj kev kub ntxhov.
** Txhim khu kev sib cuag: ** Qhov kev sim clamps * yuav tsum * ceev ceev rau lub busbar lossis lub davhlau ya nyob twg hauv kev sim. Kev sib cuag tsis zoo ua rau muaj kev tiv thaiv ntau dhau, ua rau muaj cua sov hnyav thiab ua rau cov clamps fuse (sinter).
**Circuit Impedance:** Lub impedance ntawm Circuit Court nyob rau hauv kev ntsuam xyuas yog feem ntau tsis tshua muaj siab (piv txwv li, luv luv -circuit busbar); yog li ntawd, cov cuab yeej yuav tsum ua haujlwm nyob rau hauv siab -tam sim no, qis-voltage hom. Xyuas kom meej tias cov khoom siv qis -voltage, siab - tam sim no tso zis muaj peev xwm ua tau raws li cov kev xav tau tshwj xeeb ntawm kev sim.
**Grounding:** Cov khoom siv chassis * yuav tsum * muaj kev ntseeg tau hauv av.
3. Kev soj ntsuam cov txheej txheem
** Kev ntsuas kub:** Thaum lub sij hawm ntev ntawm qhov siab - cov zis tam sim no, saib xyuas qhov ntsuas kub ntawm qhov ntsuas thiab cov neeg nyob hauv kev sim ntsuas kom tsis txhob muaj cua sov.
** Kev soj ntsuam ntsuas: ** Ua tib zoo saib xyuas lub ammeter thiab voltmeter kom paub meej tias tam sim no tseem nyob ruaj khov ntawm tus nqi teev thiab qhov voltage tsis tshaj nws qhov txwv.
4. Ib puag ncig yuav tsum tau muaj
** Qhov cua thiab cua sov Dissipation:** Cov cuab yeej ua kom muaj cua sov ntau thaum ua haujlwm; yog li ntawd, yuav tsum tau ua kom muaj cua txaus txaus.
**Site Enclosure:** Qhov chaw xeem yuav tsum tau cordoned tawm nrog cov teeb meem thiab cim nrog cov cim ceeb toom los tiv thaiv cov neeg ua hauj lwm tsis tau tso cai los ntawm inadvertently nkag mus rau hauv lub cheeb tsam.
