Gushakisha ibintu biranga voltage nkeya DC 500V SPD STGE ARTER

Mu isi y'amashanyarazi, amashanyarazi n'ibikoresho bya elegitoroniki ahura n'iterabwoba rihoraho mu mvururu z'amashanyarazi zidateganijwe zishobora gutera ibyangiritse no guhungabana.Umukinnyi muto wa voltageKugaragara nkabarinda abarinzi bashinzwe amashanyarazi, gutanga uburinzi bwingenzi kuri voltage yinzozi no kugabanuka bishobora guhitana ibikoresho byoroshye. Ibi bikoresho bihanitse bikora nk'inzitizi zikomeye, gutabaza no kohereza ingufu z'amashanyarazi zikabije kubera ibikorwa remezo bikomeye, bityo bikabungabunga ubunyangamugayo n'imikorere ya mudasobwa, imashini z'itumanaho, na elegitoroniki.

Gukorera hejuru ya voltage zitandukanye, mubisanzwe muri sisitemu yo hasi nka sisitemu 500V DC, kwishyurwa kwungurube bakoresha ikoranabuhanga rihamye kugirango tumenye kandi tudatesha agaciro amashanyarazi ashobora gusenya muri miliseconds. Mugukuramo, gukomera, cyangwa kuyobya amashanyarazi, ibi bikoresho birinda ibikoresho byangiza, bigabanya ibiciro byo kubungabunga, no kuzamura sisitemu muri rusange. Kubera ko mu kurinda ibikoresho by'ubuvuzi buhanitse mu bitaro byo kurengera Sisitemu ikomeye yo kurwanya inganda n'inzu yo mu rugo, umuryango wa Voltage uhagarare uhagarariye igisubizo cy'ikoranabuhanga mu gihe cya none, mu gukumira kwangirika kw'amashanyarazi.

Kurinda voltage

Gutembera kwishyurwa bikorwa kugirango bikore mu rwego rwo kurinda voltage (mubisanzwe bikemura uburyo buke bwa voltage muri 50v kugeza 19V AC cyangwa DC. Ubu buryo butandukanyemerera kurinda ibikoresho by'amashanyarazi n'ibikoresho bya elegitoroniki mu nganda zitandukanye. Ubushobozi bwibikoresho byo gucunga itandukaniro rya voltage butuma kurinda byuzuye ibipfukisho bito ndetse nibizunguruka byingenzi bya voltage. Mubuyobozi neza voltage, surge Argerest irinda ibikoresho byangirika mugihe ukomeje imikorere myiza y'amashanyarazi.

Igihe cyo gusubiza igihe

Kimwe mubintu bikomeye cyane byihuta voltage voltage arter nigisubizo cyigihe gito cyigihe gito. Ibikoresho byo gukingira bigezweho birashobora kubyitwaramo no kudindira bishobora kwangiza amashanyarazi muri Nanoseconds, akenshi bitarenze 25 nanoseconds. Iyi mizi-igisubizo cyihuse cyemeza ko ibice bya elegitoroniki byitiriwe bikingiwe na voltage yangiza mbere yuko bishobora gutera ibyangiritse. Uburyo bwo gusubiza vuba bukoresha tekinoroji ya semicnductor nkuru yicyuma (mogs) hamwe na gaze ibituba byoroshye kumenya no kuyobya imbaraga zumuriro.

Kwerekana no gutesha agaciro kwerekana

Abaterankunga bakuze barimo ikoranabuhanga ryo kwishyuza kwishyiriraho kwemerera gukomeza ubushobozi bwo kurinda kabura na nyuma yibyabaye byinshi byo kwiyongera. Ibi bikoresho byateye imbere bikoresha ibikoresho byihariye n'amahame agenga imihangayiko yimbere kandi agabanya ubuyamamare. Incuro nyinshi zigezweho zirimo ibipimo byubatswe cyangwa gukurikirana sisitemu zitanga ibimenyetso bisobanutse mugihe ubushobozi bwo kurinda ibikoresho bwagabanutse cyane. Iyi mikorere iremeza ko abakoresha bashobora gusimbuza neza gutora burundu mbere yo gutsindwa burundu, birinda inkumi zitunguranye. Uburyo bwo kwikiza ubusanzwe bukubiyemo indangantego ya okiside ya valeside (mov) ishobora gusubirwamo imihangayiko y'amashanyarazi kandi ikagumana imikorere ihamye hirya no hino.

Kwiyongera kumwanya uhanganye

Gutembera kwiyongera byateganijwe kwihanganira urwego runini ruteye imbere, mubisanzwe bapimirwa muri Kiloamperes (KA). Ibikoresho byo mu rwego rw'umwuga birashobora gukora imigezi yo kwiyongera kuva kuri 5 KA kugeza 100 KA, bitewe na porogaramu runaka. Iyi miti ihamye ihanganye nubushobozi bwo kwiyongera bushobora gucunga neza imivurungano ikabije, harimo nibibamo imirabyo, guhinduranya imbaraga, cyangwa guhungabanya amashanyarazi. Ubukwe bufite ubushobozi bujyanye nibice byimbere byimbere nkibikoresho byihariye bya semiconductor, inzira zakozwe na precion, hamwe nuburyo bwo gucunga ubushyuhe. Ibi bishushanyo byemerera gutora kwiyongera kwihuta cyane ingufu z'amashanyarazi zitabangamiye imikorere yo kurinda igihe kirekire cyangwa bigatuma ibyago byisumbuye bihujwe na sisitemu y'amashanyarazi.

Ubushobozi bwo kwinjira

Kuzenguruka abarushye byateguwe hamwe nubushobozi bukomeye bwo kwinjiza ingufu, bipimirwa mu fatizo. Ukurikije icyitegererezo cyihariye no gusaba, ibi bikoresho birashobora gukuramo imbaraga zo kwica kuva kuri 200 kugeza 6.000. Ibipimo byinshi byerekana ubushobozi bwo kurinda uburinzi, kwemerera igikoresho guhangana nibyabaye byinshi byo kwiyongera utabangamiye imikorere yacyo yo kurinda. Uburyo bwo kwinjiza ingufu busanzwe burimo ibikoresho byihariye bishobora guhita bitandukanya byihuse imbaraga z'amashanyarazi n'ubushyuhe, kubibuza kwamamaza binyuze muri sisitemu y'amashanyarazi no kwangiza ibikoresho by'amashanyarazi.

Uburyo bwinshi bwo kurinda

Iterambere rya VoltageTanga uburinzi bwuzuye hejuru yuburyo bwinshi bwamashanyarazi, harimo:
- Uburyo busanzwe (umurongo-utabogamye)
- Uburyo busanzwe (umurongo-kugeza hasi)
- Uburyo butandukanye (hagati y'abayobora)
Ubu buringanire-muburyo bwinshi buremeza ubwishingizi bukabije bwo kwirinda imivuruke itandukanye, ikemura inzira zitandukanye zo gukwirakwiza. Mukingira uburyo bwinshi icyarimwe, ibi bikoresho bitanga uburyo bwo kwirwanaho mu kirere bugoye amashanyarazi na sisitemu ya elegitoroniki.

Ubushyuhe no kwihangana ibidukikije

Umwuga wo kwizihiza umwuga wubatswe kugirango uhangane nibidukikije bivuguruzanya. Mubisanzwe bishyirwa ku bushyuhe buva kuri -40? C to +85? C, kwemeza imikorere ihamye hirya no hino mubidukikije bitandukanye. Byongeye kandi, ibi bikoresho biranga uruzitiro rukomeye rurinda ibice byimbere mu mukungugu, ubuhehere, hamwe nubushake bwakani. Ibikoresho byihariye byo kumarana hamwe nibikoresho byateye imbere byongera iramba ryabo, bigatuma bakwiranywa n'inganda, ubucuruzi, ndetse no guturamo.

Ubushobozi bwo gukurikirana no gukurikirana

Inshuro zigezweho zirimo zinjiza ikoranabuhanga ryambere rikora imiterere-nyayo. Ibikoresho byinshi byerekana ibipimo byerekana uburyo bwo kwerekana imikorere, uburyo bwo kunanirwa, no gukwirakwira. Ibikoresho bimwe bifatika bitanga ubushobozi bwo gukurikirana kure binyuze muri digitale, bituma habaho isuzuma ryimikorere yo kurinda umutekano. Ibiranga Gukurikirana bifasha kubungabungwa, gufasha abakoresha kumenya kwangiza mbere yo gutsindwa kw'ibitago bibaho.

Igishushanyo cyoroshye kandi cya modular

Kwiyongera kw'ibice byo kwiyongera byakozwe mu kirere no guhinduka mubitekerezo. Ibintu byabo byiza byemerera guhuza ibintu bidafite ishingiro mumashanyarazi ariho, imbaho ​​zo kugabura, nibikoresho byibikoresho. Ibishushanyo mbonera byoroshya byoroshye kwishyiriraho, gusimbuza, no kuzamura sisitemu. Model nyinshi zishyigikira gari ya mocol igenda, ibirindiro byamashanyarazi, kandi bigatanga uburyo bwo guhuza hamwe, butuma guhuza amashanyarazi atandukanye.

Kubahiriza no kwemeza

Inkongo zifite ireme ryinshi zirimo gahunda zidasanzwe zo kwipimisha kandi zemeza, dukurikiza amahame mpuzamahanga nka:
- IEC 61643 (ibipimo bya ngombwa komisiyo mpuzamahanga)
- IEEE C62.41 (Ikigo cy'amashanyarazi na elegitoroniki ibyifuzo)
- UL 1449 (Abakinnyi ba laboratoire Ibipimo byumutekano)
Iyi mpamyabumenyi yemeza imikorere yigikoresho, kwizerwa, hamwe nibiranga umutekano. Kubahiriza biremeza ko kwiyongera kwubaka guhuza ibisabwa mu nganda kandi bitanga uburinzi bwizewe kuri sisitemu y'amashanyarazi na porogaramu.

Umwanzuro

Umukinnyi muto wa voltageGuhagararira igisubizo kinegura tekinoroji yo kurinda ibikorwa remezo bigenda byiyongera. Muguhuza ikoranabuhanga rya semiconductor ryateye imbere, ubwo buhangane, kandi ingamba zuzuye, ibi bikoresho birinda ibikoresho bihenze kandi byihariye biva mu mivurungano y'amashanyarazi. Mugihe twishingikirije kuri sisitemu ya elegitoronike ikomeje kwiyongera, akamaro ko kurinda bikomeye bigenda byiyongera. Gushoramari mu rubuga rwo mu rwego rwo hejuru ntabwo ari ugutekereza kwa tekinike gusa ahubwo uburyo bushoboka bwo kubungabunga ibikoresho bihenze, no gukumira imigenzo ihenze.
