Ibibazo byo kurwanya tester

Ikizamini cyo kurwanya ibihugu birakwiriye gupima agaciro ko kurwanya ibikoresho bitandukanye birimo hamwe no kurwanya intangarugero, insinga n'ibikoresho by'amashanyarazi no kwirinda impanuka nkamashanyarazi Abahitanwa no kwangiza ibikoresho.

Ibibazo bisanzwe byo kurwanya testers niyi ikurikira:

1. Iyo usangiye umutwaro wo kurwanya umutwaro, ni irihe sano riri hagati yumuzunguruko mugihe gito cyakarere kibangamira tester hamwe namakuru yapimwe, kandi kuki?

Ibisohoka bigufi byumuzunguruko bya test of the Testers tester birashobora kwerekana ko intangiriro yimbere ya voltage.

Ibizamini byinshi byikizamini ni imitwaro, nkinsinga ndende, moteri zifite ubushobozi bwinshi, ibibitekerezo, mugihe ikintu cyapimwe cyabayemo, intangiriro yikizamini cyo kurwanya tester igomba kwishyuza tester igomba kwishyuza Capally binyuze mu kurwanya imbere, hanyuma wishyure buhoro buhoro voltage kubisohoka byashyizwe ahagaragara voltage ya voltage ya voltage ya voltage africance tester. Niba ubushobozi bwo kwitabwaho bwikintu cyapimwe ari kinini, cyangwa kurwanya imbere inkomoko ya voltage ndende nini, inzira yo kwishyuza izafata igihe kirekire.

Uburebure bwacyo burashobora kugenwa nibicuruzwa bya R na C biremereye (mumasegonda), ni ukuvuga t = r * imitwaro.

Rero, mugihe cyo kwipimisha, umutwaro wa camputike ukeneye kwishyurwa muri voltage yikizamini, kandi umuvuduko wihuta dv / dt uhwanye na gahunda yo kwishyuza i no kwikorera ubushobozi bwo kwishyuza i no kwikorera ubushobozi C. Iyo ni dv / dt = i / c.

Kubwibyo, ibitero bito byimbere ni, nini nini yo kwishyuza ni, kandi byihuse kandi bihamye ibisubizo byikizamini ni.

2. Niyihe mikorere ya "G" iherezo ryibikoresho? Mubihe byikizamini cya voltage ndende no kurwanya cyane, kuki igikoresho gifitanye isano na "G"?

Icyiciro cya "G" cyanyuma cyigikoresho ni umupaka ukingira, kikoreshwa mugukuraho imbaraga zubushuhe numwanda mubidukikije kubisubizo byo gupima. Iherezo ryibikoresho ni ukurenganya kurimbuka hejuru yikintu cyageragejwe, kugirango ubungubu butanyuze mukipe yikizamini cyikizamini cyigikoresho, ikuraho ikosa ryatewe nubusa. Mugihe ugerageza agaciro gakomeye, g iherezo rigomba gukoreshwa.

Muri rusange, G-terminal irashobora gusuzumwa iyo iri hejuru ya 10G. Ariko, uru rutera rwo kurwanya ntabwo rwuzuye. Birasukuye kandi byumye, kandi ingano yikintu igomba gupimwa ni nto, bityo irashobora guhagarara idapima 500G kuri g-impera; Mu bihe bitose kandi byanduye, kurwanya hasi nabyo bikenera g terminal. By'umwihariko, iyo hagaragaye ibisubizo bigoye gusigaje mugihe upima cyane, G-terminal irashobora gusuzumwa. Byongeye kandi, twakagombye kumenya ko umutware wa terminal g udahujwe nigice cyingabo, ariko gihujwe na susulator hagati ya L na E, cyangwa mumutsinga mwinshi, ntabwo ari izindi nsinga.

3. Kuki ari ngombwa gupima gusa ko kurwanya gusa, ahubwo ni kandi igipimo cyo gushiramo na polarique mugihe cyo gupima insulation?

Pi ni indangagaciro yerekana, bivuga kugereranya no kurwanya inkeri muminota 10 n'umunota 1 mugihe cyo kwipimisha;

Dar nigipimo cyimirire ikurura, bivuga kugereranya hagati yo kurwanya ibiganiro mumunota umwe kandi ko muri 15s;

Mu kizamini cy'Amakuru, abasuhuza agaciro mugihe runaka ntigishobora kwerekana neza ireme ryimikorere yo kwipimisha. Ibi biterwa n'impamvu ebyiri zikurikira: Ku ruhande rumwe, inyongeramubano zo kurwanya imikorere imwe y'ibikoresho ni nto iyo ingano nini, kandi nini iyo ingano ari nto. Kurundi ruhande, harashobora kwishyurwa hamwe nibikorwa byo kwishyurwa muguhindura iyo voltage ndende ikoreshwa. Kubwibyo, sisitemu yubumenyi isaba ko igipimo cyingenzi cyo kwinjizwa (R60 kuri R15s) na polarisation yerekanaga mu kizamini cyibanze, umugozi, moteri nibindi bihe bishobora gucirwa urubanza na aya makuru.

4. Kuki bateri nyinshi zishobora kurwanya testers tester itanga voltage ndende ya dc? Ibi bishingiye ku ihame ryo guhinduka DC. Nyuma yo gutunganya imitcuit yumuriro, voltage yo hasi yazamuwe hejuru yo gusohoka hejuru dc voltage. Nubwo voltage ndende ikozwe hejuru, imbaraga zisohoka ni nto (ingufu nke na ntoya).

Icyitonderwa: Nubwo imbaraga ari nto cyane, ntabwo zisabwa gukoraho iperereza ryikizamini, hazakomeza kwigana.
