Ibyiciro byingenzi nibicuruzwa biranga amashanyarazi make yumuriro (guhinduranya ikirere)

Ibyiciro byingenzi nibicuruzwa biranga voltage nkeya imiyoboro yamashanyarazi (guhinduranya ikirere)

Uburyo nyamukuru bwo gutondekanya ibyuma bitwara amashanyarazi make, bishingiye kumiterere yabyo, birakinguye nubwoko bwibikoresho, nibisanzwe mubicuruzwa. Gufungura byitwa kandi ubwoko bwikadiri cyangwa ubwoko rusange, mugihe ibikoresho byitwa ubwoko bwa plastiki shell.

Ihame rusange ryo gutoranya kumashanyarazi.

Umuvuduko ukabije wumurimo wumurongo wumurongo wumurongo ugomba kuba munini cyangwa uhwanye numuvuduko wapimwe wumurongo wumurongo.Umuyoboro wapimwe wumurongo wumuzunguruko ugomba kuba munini cyangwa uhwanye numuyoboro wumutwaro wumurongo. kurekura ako kanya kumeneka wumuzunguruko.Umubyigano wapimwe wumuriro wa volvoltage urekura icyuma cyumuzunguruko ugomba kuba uhwanye na voltage yagenwe kumurongo.Umuvuduko wapimwe wa shunt irekura amashanyarazi yamashanyarazi agomba kuba angana na voltage yo kugenzura amashanyarazi. Moderi zimwe zumuzunguruko zemerera gusa umurongo winjira uhereye hejuru, mugihe moderi zimwe zemerera umurongo kwinjira kuva hejuru cyangwa hepfo.

Amahame yo gutoranya amashanyarazi make

1.Menya ubwoko nuburyo bwo gukingira kumashanyarazi ukurikije ibisabwa byo kurinda umurongo: hitamo ubwoko bwikadiri, ubwoko bwibikoresho cyangwa ubwoko bugabanya imipaka, nibindi.
Ubwoko bwibikoresho byumuzunguruko: Ifite igishishwa cya pulasitike gikingira, cyubatswe muri sisitemu yo guhuza, arc kuzimya icyumba no kurekura, nibindi, kandi birashobora gufungwa intoki cyangwa amashanyarazi (kubimena amashanyarazi manini). Ifite ubushobozi bukomeye bwo kumeneka, imbaraga zidasanzwe, kandi ugereranije nibikorwa byuzuye byo kurinda. Ikoreshwa cyane mumirongo yo gukwirakwiza. Kugeza ubu, ibicuruzwa bikunze gukoreshwa birimo DZ15, DZ20, DZX19, C45N (ubu byazamuwe kuri C65N) hamwe nizindi seri. Muri byo, C45N (C65N) yameneka yumuzunguruko ifite ibyiza byubunini buto, ubushobozi bukomeye bwo kumeneka, imikorere myiza igabanya imikorere, imikorere yoroshye, hamwe nicyitegererezo cyuzuye nibisobanuro. Birashobora guhuzwa byoroshye mubice bibiri, pole eshatu na pole enye zomuzunguruko zishingiye kumiterere imwe, kandi zikoreshwa cyane mumashami yamurika yabaturage hamwe numurongo wamashami ya 60A na munsi (cyane cyane bikoreshwa mumirongo yinjira kubakoresha kubakoresha no gucana amashami mumasoko yubucuruzi).
2.Ibikoresho byo mu bwoko bwa frake-yamashanyarazi yameneka: ubushobozi bunini, imbaraga zogucika intege zumuzunguruko, imbaraga zidasanzwe, zikwiranye na AC 50Hz, umuyoboro wa voltage 380V wagabanijwe, nkuburinzi nyamukuru bwimirongo ikwirakwizwa. Imashini yamashanyarazi yamashanyarazi igizwe ahanini na sisitemu yo guhuza, uburyo bwo gukora, kurekura inshuro nyinshi, kurekura shunt, kurekura amashanyarazi, ibikoresho hamwe nibikoresho, nibindi byose. Kugeza ubu, ibisanzwe bikoreshwa muburyo bwa frame-voltage yamashanyarazi yamenetse mugihugu cyanjye ni DW15, ME, AE, AH nizindi seri. Imiyoboro ya DW15 yamashanyarazi yatunganijwe kandi ikorerwa mugihugu cyanjye. Urukurikirane rwuzuye rurimo moderi nyinshi nka 1000, 1500, 2500, na 4000A. ME, AE, na AH zikurikirana zumuzunguruko zakozwe hifashishijwe ikoranabuhanga ryatumijwe mu mahanga, hamwe nibisobanuro byuzuye hamwe na moderi (mpindura urwego rwubu ruri hagati ya 630A kugeza 5000A, urwego 13 rwose), kandi ubushobozi bwo kumena amanota bukomeye kuruta ubwa DW15. Bakunze gukoreshwa mukurinda nyamukuru kurinda amashanyarazi make.
3.Icyuma cyumuzunguruko cyubwenge: Kugeza ubu, hari ubwoko bubiri bwubwenge bwumuzunguruko bwubwenge bukorerwa mugihugu cyanjye: ubwoko bwikadiri nubwoko bwa plastike. Ubwoko bwa frame yamashanyarazi yamashanyarazi akoreshwa cyane cyane nkumuzunguruko wingenzi wa sisitemu yo gukwirakwiza ibyuma byikora, mugihe ibyuma bya pulasitike byubwoko bwamashanyarazi bikoreshwa cyane mugukwirakwiza amashanyarazi mumiyoboro yo gukwirakwiza no kugenzura no kurinda imirongo nibikoresho bitanga amashanyarazi. Byakoreshejwe nkigenzura ryibyiciro bitatu byimodoka idafite moteri. Ibiranga imiyoboro yamashanyarazi ifite ubwenge ni uko bakoresha imashini zifite ubwenge (ibikoresho byurugendo rwubwenge) hamwe na microprocessor cyangwa microcomputer imwe ya chip nkibyingenzi, kandi bafite imirimo yo kugenzura kumurongo, guhinduranya byikora, gupima, kwipimisha, kwisuzumisha, itumanaho, nibindi byerekeranye namashanyarazi yumuzunguruko (ikigezweho, voltage, imbaraga, ibintu byingufu, nibindi), kandi birashobora kwerekana, gushiraho no kugenzura ibipimo byibikorwa mubikorwa byo kurinda, guhindura imikorere, ububiko budahindagurika bwibibazo. Imikorere isanzwe yo mumashanyarazi yamashanyarazi irimo DW45, DW40, DW914 (AH), DW18 (AE-S), DW48, DW19 (3WE), DW17 (ME), nibindi.

Mugihe uhitamo icyuma kizunguruka, hagomba gusuzumwa amahame akurikira:

1. Umuvuduko wapimwe (UN) wumucyo wumuzingi ugomba kungana cyangwa kurenza voltage yagenwe kumurongo urinzwe.
2. Umuvuduko uringaniye wumuzenguruko wumurongo wumuriro wa volvoltage ugomba guhuza na voltage yagenwe kumurongo urinzwe.
3. Ikigereranyo cyagenwe cyumuzenguruko wumuzenguruko hamwe no kurekurwa kwayo kugomba kuba kurenze cyangwa kangana numuyoboro wabazwe wumuzingi urinzwe.
4. Ubushobozi buhebuje bwo kumeneka kumashanyarazi bugomba kurenza agaciro keza k'umurongo muto muto-wumurongo wumurongo.
5. Ibiranga kurinda ibiranga uruziga rwo hejuru nu munsi mumurongo wo gukwirakwiza bigomba guhuzwa, hamwe nurwego rwo hasi rwo kurinda rwashyizwe munsi kandi ntiruhuze nibiranga urwego rwo hejuru.
6. Umwanya muremure wo gutinda kugendagenda kumashanyarazi yameneka bigomba kuba munsi yumurongo wemewe wogukomeza.

Kumashanyarazi yamashanyarazi yamashanyarazi, amahame yo guhitamo akurikira:

1. Igenamiterere ryumuzenguruko wumurongo wigihe kirekire wogukora ntigomba kurenza ubushobozi bwemewe bwo gutwara insinga. Kubikoresho byinsinga na kabili, nibyiza gukoresha 80% byinsinga na kabili byemewe byogutwara.
2. Igihe gisubizwa inshuro eshatu-ndende-gutinda gukora igenamigambi ryagaciro rigomba kuba rirenze cyangwa rihwanye nigihe cyo gutangirira kuri moteri hamwe nintangiriro yo gutangira kumurongo.
3. Agaciro gahita gashiraho agaciro kagomba kuba byibuze inshuro 1,1 yumubare wumurongo wo kubara umurongo (Ijx) hamwe nigicuruzwa cya moteri itangira coefficient yingaruka (k1, mubisanzwe 1.7-2), moteri itangira amashanyarazi menshi (k), hamwe numuyoboro wagenwe wa moteri nini (Icdm).

Kubimoteri birinda moteri, amahame akurikira akurikizwa:

1. Umwanya muremure wo gutinda kugena agaciro bigomba kungana na moteri yagenwe.
2. Umuyoboro uhita uhita kumeneka wumuzingi urinda moteri ya cage ugomba kuba wikubye inshuro 8-15 moteri yagenwe na moteri, mugihe kuri moteri ya rot rot, igomba kuba inshuro 3-6 moteri yagenwe.
3. Igihe cyo kugaruka kumwanya wikubye inshuro esheshatu gutinda kugihe cyagenwe kigomba kuba kinini cyangwa kingana nigihe moteri yatangiriye, hamwe namahitamo ya 1S, 3S, 5S, 8S, 12S, cyangwa 15S ukurikije uburemere bwumutwaro mugitangira.

Mugihe uhuza ibice byumuzunguruko hamwe na fus, hagomba gusuzumwa amahame akurikira:

1. Niba ibyateganijwe bigufi byumuzunguruko mugihe cyo kwishyiriraho biri munsi yubushobozi bwo kumeneka kumashanyarazi, fuse irashobora gukoreshwa nkuburinzi bwinyuma bitewe nubushobozi bwayo bukomeye bwo kumeneka. Nkuko bigaragara ku gishushanyo cya 1, imiterere ya backup fuse iranga (1) ihuza nibice byumuzunguruko (2). Mugihe habaye umurongo mugufi-umuzenguruko, igihe cyo kumena fuse ni kigufi kuruta icyuma cyumuzunguruko, bikarinda umutekano wumuzunguruko. Ihererekanyabubasha kubiranga rishobora gutoranywa kuri 80% byumuzunguruko wumurongo wagabanutse ubushobozi buke bwo kumeneka.
2. Fuse igomba gushyirwaho kuruhande rwingufu zumuzunguruko kugirango ikoreshwe neza.
