Inzitizi z'umutekano zigabanya ingufu zinjira kurubuga, ni ukuvuga voltage n’umupaka uriho, kugirango umurongo wumurima utazabyara ibicu munsi yigihugu icyo aricyo cyose, kugirango bidatera igisasu.Ubu buryo butarinda guturika bwitwa umutekano w'imbere.Inzitizi z'umutekano duhuriyemo zirimo inzitizi z'umutekano wa zener, inzitizi z'umutekano wa transistor, hamwe n'inzitizi z'umutekano zitandukanya.Izi nzitizi z'umutekano zifite inyungu zazo kandi zose ni abafasha mubikorwa byinganda.Abanditsi bakurikira ba Suixianji.com bazamenyekanisha ihame ryakazi nimirimo yinzitizi yumutekano, kimwe no gutandukanya inzitizi yo kwigunga.
Inzitizi z'umutekano ni ijambo rusange, rigabanijwemo inzitizi z'umutekano wa zener n'inzitizi z'umutekano zo kwigunga, inzitizi z'umutekano zitandukanijwe zitwa inzitizi yo kwigunga.
Uburyo inzitizi yumutekano ikora
1. Ihame ryakazi ryo gutandukanya ibimenyetso:
Ubwa mbere, ikimenyetso cya transmitter cyangwa igikoresho gihindurwa kandi gihindurwa nigikoresho cya semiconductor, hanyuma kigatandukana kandi kigahindurwa nigikoresho cyumva urumuri cyangwa rukuruzi rukuruzi, hanyuma kigacika intege hanyuma kigasubira mubimenyetso byambere mbere yo kwigunga, nimbaraga gutanga ibimenyetso byitaruye byitaruye icyarimwe..Menya neza ko ibimenyetso byahinduwe, amashanyarazi nubutaka byigenga rwose.
2. Ihame ryakazi ryinzitizi yumutekano wa Zener:
Igikorwa nyamukuru cyinzitizi yumutekano ni ukugabanya ubushobozi bubi bwahantu hizewe bwo kwinjira ahantu hateye akaga, no kugabanya voltage numuyoboro woherejwe ahantu hateye akaga.
Zener Z ikoreshwa mukugabanya voltage.Iyo voltage ya loop yegereye agaciro k'umutekano ntarengwa, Zener irakinguye, kugirango voltage hejuru ya Zener ihore ibitswe munsi yumupaka wumutekano.Resistor R ikoreshwa mukugabanya ikigezweho.Iyo voltage igarukira, guhitamo neza agaciro ka résistoriste birashobora kugabanya umuvuduko uri munsi yumutekano ntarengwa.
Imikorere ya fuse F ni ukurinda voltage yumuzingi kugabanya kunanirwa bitewe numuyoboro wa zener uhuhwa numuyoboro munini utemba mugihe kirekire.Iyo voltage irenze igipimo cyumubyigano ntarengwa ikoreshwa kumuzunguruko, umuyoboro wa Zener urafungura.Niba nta fuse ihari, umuyoboro unyura mu muyoboro wa Zener uzamuka bitagira akagero, kandi amaherezo umuyoboro wa Zener uzaturika, ku buryo ruswa itakaza umupaka wa voltage.Kugirango umenye neza ko ruswa ya voltage igabanya umutekano, fuse ihuha inshuro icumi kurenza Zener ishobora guhuha.
3. Ihame ryakazi ryikimenyetso cyitaruye inzitizi yumutekano:
Ugereranije na bariyeri yumutekano wa zener, inzitizi yumutekano yitaruye ifite umurimo wo kwigunga kwa galvanic hiyongereyeho imirimo ya voltage no kugabanya ubu.Inzitizi yo kwigunga isanzwe igizwe nibice bitatu: igice cyo kugabanya ingufu za loop, igice cyo kwigunga cya galvanic hamwe nigice cyo gutunganya ibimenyetso.Igice cyo kugabanya ingufu ni igice cyibanze cyumutekano.Mubyongeyeho, hariho amashanyarazi yingirakamaro yo gutanga ibikoresho byo gutwara ibibuga hamwe no gutahura ibikoresho byo kugura ibimenyetso.Igice cyo gutunganya ibimenyetso gikora ibimenyetso bikurikije ibisabwa byinzitizi yumutekano.
Uruhare rwinzitizi z'umutekano
Inzitizi z'umutekano ni ibikoresho byumutekano byingirakamaro mu nganda nyinshi.Ikoresha cyane cyane cyangwa ikoresha ibikoresho bimwe na bimwe byaka, nk'amavuta ya peteroli hamwe n’ibikomoka kuri peteroli, inzoga, gaze gasanzwe, ifu, n'ibindi. Kumeneka cyangwa gukoresha nabi kimwe muri ibyo bintu bizavamo ibidukikije biturika.Kubwumutekano winganda nabantu ku giti cyabo, birakenewe ko ibidukikije bikora bitazatera ibisasu.Mubikorwa byo kurinda, inzitizi yumutekano igira uruhare runini.uruhare rukomeye,
Inzitizi yumutekano iri hagati yicyumba cyubugenzuzi nibikoresho byimbere imbere ahantu hateye akaga.Ifite uruhare runini rwo kurinda.Ibikoresho byose byamashanyarazi mubikorwa byo kubyaza umusaruro bishobora gutera guturika, ibishashi bitandukanye byo guterana amagambo, amashanyarazi ahamye, ubushyuhe bwinshi, nibindi byose byanze bikunze mubikorwa byinganda, bityo inzitizi yumutekano itanga ingamba zo kurinda umusaruro winganda.
Hagomba kubaho sisitemu yizewe cyane mugihe cyo kwishyiriraho, kandi ibikoresho byo mumurima biva ahantu habi bigomba kuba byitaruye.Bitabaye ibyo, ibimenyetso ntibishobora koherezwa neza nyuma yo guhuzwa nubutaka, bizagira ingaruka kumikorere ya sisitemu.
Itandukaniro hagati yinzitizi yumutekano ninzitizi yo kwigunga
1. Ikimenyetso cyo kwigunga
Rinda urwego rwo hasi rwo kugenzura.
Ongeraho ingaruka zurusaku rwibidukikije kumuzingo wikizamini.
Kurwanya kwivanga kumurongo rusange, guhinduranya inshuro, solenoid valve na pulse itazwi kubikoresho;icyarimwe, ifite imirimo yo kugabanya voltage no kugereranya ibiciro kubikoresho byo hasi, harimo transmitter, ibikoresho, guhinduranya inshuro, solenoid valve, PLC / DCS ibyinjira nibisohoka hamwe nuburyo bwo gutumanaho kurinda kwizerwa.
2. Inzitizi z'umutekano zitaruye
Inzitizi yo kwigunga: Inzitizi y’umutekano yitaruye, ni ukuvuga, kongeramo ibikorwa byo kwigunga hashingiwe ku mbogamizi y’umutekano, ishobora kubuza kwivanga kw’umuyaga w’ubutaka ku kimenyetso, kandi icyarimwe ukarinda sisitemu ingaruka z’ingufu z’ingaruka zituruka kuri ibibera.Kurugero, niba nini nini yinjiye mumurongo, bizaca inzitizi yo kwigunga bitagize ingaruka kuri IO.Rimwe na rimwe, birashobora kandi kumvikana nkumuntu wigunze udafite imikorere yumutekano wumutekano, ni ukuvuga, ifite gusa umurimo wo kwigunga kugirango wirinde kwangiriza ibimenyetso no kurinda sisitemu IO, ariko ntabwo itanga umuzenguruko wimbere.Kubidasaba guturika-gusaba.
Ifata imiterere yumuzunguruko itandukanya amashanyarazi ibyinjira, ibisohoka nimbaraga zitangwa hagati yabyo, kandi byujuje ibisabwa byumutekano wimbere kugirango bigabanye ingufu.Ugereranije nimbogamizi zumutekano wa Zener, nubwo igiciro gihenze, ibyiza byimikorere byayo bizana inyungu nyinshi kubakoresha porogaramu:
Bitewe no gukoresha inzira eshatu zo kwigunga, ntihakenewe umurongo uhuza sisitemu, izana ibyoroshye cyane mugushushanya no kubaka ahakorerwa.
Ibisabwa kubikoresho ahantu habi biragabanuka cyane, kandi nta mpamvu yo gukoresha ibikoresho byitaruye kurubuga.
Kubera ko imirongo yerekana ibimenyetso idakeneye gusangira ubutaka, ubushobozi bwo guhagarara hamwe no kurwanya-kwivanga mubimenyetso byo gutahura no kugenzura ibizunguruka byongerewe cyane, bityo bikazamura ubwizerwe bwa sisitemu yose.
Inzitizi yumutekano yitaruye ifite imbaraga zo kwinjiza ibimenyetso byimbaraga, kandi irashobora kwakira no gutunganya ibimenyetso nka thermocouples, irwanya ubushyuhe, hamwe na frequence, ibyo inzitizi yumutekano wa zener ntishobora gukora.
Inzitizi y’umutekano yitaruye irashobora gusohora ibimenyetso bibiri byitaruye kugirango itange ibikoresho bibiri ukoresheje isoko imwe yerekana ibimenyetso, kandi urebe ko ibimenyetso byibikoresho byombi bitabangamirana, kandi icyarimwe bigateza imbere imikorere y’umutekano w’amashanyarazi hagati yahujwe ibikoresho.
Ibyavuzwe haruguru bijyanye nihame ryimirimo nimirimo yinzitizi yumutekano, hamwe nubumenyi bwo gutandukanya inzitizi yumutekano ninzitizi yo kwigunga.Ikimenyetso cyerekana ibimenyetso muri rusange bivuga ibimenyetso bitandukanya sisitemu idakomeye, irinda sisitemu yo mu rwego rwo hasi ibimenyetso byerekana ingaruka no kwivanga kwa sisitemu yo hejuru.Inzitizi yo gutandukanya ibimenyetso ihujwe hagati yumuzenguruko utekanye imbere n’umuzunguruko udafite umutekano.Igikoresho kigabanya voltage cyangwa amashanyarazi yatanzwe kumuzunguruko wimbere mumutekano muke.
