Mu rwego rwo gukumira ikibazo cyo kuva amazi, hiyongereyeho no gufunga ubutakaikirundo cyo gusharija, guhitamo uburyo bwo kurinda amazi kuva nabyo ni ingenzi cyane. Dukurikije ibipimo ngenderwaho bya GB/T 187487.1 by’igihugu, uburyo bwo kurinda amazi kuva kuri charger bugomba gukoresha ubwoko bwa B cyangwa ubwoko bwa A, butarinda amazi kuva kuri AC gusa, ahubwo bunarinda DC itera. Itandukaniro rikomeye hagati y’ubwoko bwa B n’ubwoko bwa A ni uko ubwoko bwa B bwongereye uburinzi ku mazi ava kuri DC. Ariko, bitewe n’ingorane n’ibiciro byo kumenya ubwoko bwa B, abakora benshi muri iki gihe bahitamo ubwoko bwa A. Ingaruka nini zo kuva kuri DC kuva kuri DC si imvune ku muntu, ahubwo ni ibyago byihishe biterwa no kwangirika kw’igikoresho cyo kurinda amazi kuva kuri DC cya mbere. Dushobora kuvuga ko uburyo bwo kurinda amazi kuva kuri charger piles buriho ubu bufite ibyago byihishe ku rwego rusanzwe.
Ubwoko bwa A: Ikigabanya urujya n'uruza rw'amashanyarazi
Imashini igabanya urujya n'uruza rw'amashanyarazi yo mu bwoko bwa A n'imashini igabanya urujya n'uruza rw'amashanyarazi yo mu bwoko bwa AC muri rusange ni bimwe mu bijyanye n'imikorere (agaciro k'urujya n'uruza gapimirwa binyuze muri transformateur y'amashanyarazi ikoresha zeru), ariko imiterere ya rukuruzi ya transformateur irarushaho kuba myiza. Ituma igwa mu bihe bikurikira:
(a) Kimwe n'ubwoko bwa AC.
(b) Umuyoboro wa DC usigaye utera.
(c) Umuyoboro wa DC ugenda neza wa 0.006A ushyirwa hejuru y'umuyoboro wa DC usigaye utera.
Imashini igabanya urujya n'uruza rw'amashanyarazi yo mu bwoko bwa B —— (UBUSHINWA ishobora gukora RCD Type B)
Utwuma duto two mu bwoko bwa B dushobora kurinda neza ibimenyetso bya AC byo mu bwoko bwa sinusoidal, ibimenyetso bya DC bitera imbaraga n'ibimenyetso byoroshye, kandi dufite ibisabwa mu miterere yabyo kurusha utundi duto two mu bwoko bwa A. Bituma habaho kugwa mu buryo bukurikira:
a) Kimwe n'ubwoko bwa A.
b) Umuvuduko w'amashanyarazi usimburana wa sinusoidal ukagera kuri 1000 Hz.
c) Umuyoboro wa AC usigaye urimo umuyoboro wa DC ugenda neza inshuro 0.4 z'umuyoboro wa AC usigaye
d) Umuyoboro wa DC usigaye utera hejuru y’umuyoboro usigaye utera hejuru y’umuyoboro usigaye ukubye inshuro 0.4 z’umuyoboro usanzwe cyangwa umuyoboro wa DC ugenda neza wa 10mA (uwo ari wo wose uruta uwo ari wo wose).
e) Imiyoboro ya DC isigaye ikorwa n'imiyoboro ikurikira yo gukosora:
- umurongo uhuza ikiraro cy'igice cy'umuraba n'umurongo uhuza ibyuma bigabanya amashanyarazi bifite inkingi ebyiri, eshatu na enye.
- Ku byuma bigabanya ikirere cy’ubutaka gifite inkingi 3 n’inkingi 4, ibyuma 3 bifite inyenyeri zihuza igice cy’umuraba cyangwa ibyuma 6 bifite uruziga rw’umuraba.
