Ese ibikoresho byo kurinda indwara y’ubwiyongere bw’izuba ni itegeko?

Ndacyibuka umunsi inkuba imwe yakubise umukiriya wanjye ama-€ 180.000 mu ma-PLC yakase.

Nyobora uruganda rw'ibikoresho byo gusukura rufite ubuso bwa metero kare 2,000 i Wenzhou, kandi ndakubwira: SPDs Ntabwo bihatirwa n'amategeko ahantu hose, ariko iyo ubirenzeho uba ukina urusimbi rw'igihe cyo kuruhuka, ubwishingizi, n'izina ryawe.

Hasi ndakwereka ibibazo bitanu buri muyobozi ushinzwe kugura ambaza mbere yuko atumiza B2B.

Kuki Ibikoresho byo Kurinda Ubushyuhe Ni ingenzi ku bikorwa remezo by'ubucuruzi bwawe?

Ndabona inganda zitakaza 3-5% by'inyungu ku mwaka bitewe n'ibyangiritse bikabije bya 19 € SPD yashoboraga guhagarara.

Ingufu zituruka ku nkuba, gusimbuza ibikoresho by'amashanyarazi, cyangwa moteri nini zikubita ku kabati ka 6 kV; iyo hatabayeho SPDs, ingufu zishongesha disiki, seriveri, na sensor.

Mu by'ukuri, kwiyongera kw'ingufu ni iki kandi bituruka he?

Ingufu ni umuvuduko muke w’amashanyarazi menshi umara amasegonda make ariko utwara amagana ya amperes.

Inkomoko zo hanze: inkuba, guhindura imiyoboro y'amashanyarazi, imirongo yaguye.

Inkomoko y'imbere: VFDs, robo zisudira, moteri nini za HVAC, ascenseurs.

Namaze icyumweru kimwe ngenzura imiterere y’amazi mu cyumba cyo gupakiramo ibikoresho mu Budage. Twapimye ahantu 42 harenze kV 1; nini cyane yageze kuri kV 3.8. Nta na kimwe cyaturutse ku nkubi y’umuyaga—inkubi yose yaturutse ku mashini zari mu nyubako.

Amafaranga wishyura iyo usibye SPDs

Ongeraho iyi mirongo maze SPD ya €19 isa nkaho ihendutse.

Amahame agushishikariza gushyiraho SPDs

IEC 60364-4-44 na NFPA 70 byombi bivuga: niba ingaruka z'izamuka ry'ikirere ari inkongi y'umuriro, gukomereka, cyangwa gufunga sisitemu z'umutekano w'ubuzima, ugomba kugira uburinzi bw'izamuka ry'ikirere.

Muri EU, EN 50550-2023 nshya ituma SPDs ari itegeko ku nyubako rusange n'ibigo by'amakuru.

Nubwo iyo kode itagaragara, abacuruzi b'ubwishingizi ubu bandika "ubwishingizi bw'inyongera gusa iyo SPD ishyizwemo" muri politiki z'uruganda.

Mfasha abaguzi gushyira akamenyetso mu gasanduku gasanzwe kohereza raporo z'ibizamini bivuye muri laboratwari yacu yemewe na TUV; impapuro zituma ishami ryabo rishinzwe ibyago rikomeza kwishima.

Ni gute ibikoresho byo kurinda ubucuruzi bwawe bishobora kurinda ubucuruzi bwawe ibyangiritse bihenze?

Nigeze kureba agasanduku k'ibishyimbo bikonjeshejwe gafite uburebure bwa metero 40 kuko inshuro imwe byishe PLC ikora firigo; SPD ya 35 € yari kuzigama imizigo ya 200.000 €.

SPDs zigabanya umuvuduko w’amashanyarazi mbere yuko ugera ku bice by’ingenzi, bigabanya ikiguzi cyo gusimbuza n’igihe cyo kudakora ku kigero cya 90%.

Gahunda yo kwirwanaho y'ibyiciro bitatu ndayiha buri muguzi wese

Ntwara ubwoko bwose butatu buturutse i Wenzhou kugira ngo abaguzi bashobore kugura rimwe kandi birinde ibibazo byo kuvanga.

Inkuru nyayo: uruganda rw'imodoka muri Birmingham

Bafashe ubwoko bwa mbere gusa ku muntu winjije amafaranga. Imodoka yaguye ku muhanda wa busbar yica robots eshatu za KUKA.

Twongeyeho ubwoko bwa kabiri bwa DIN-rail units iruhande rwa buri kabati. Nyuma y'umwaka umwe indi nkubi y'umuyaga yateye; robots zakomeje kubaho, zikiza ibice 120.000 by'amapawundi n'amasaha 18 yo kuruhuka.

Formula yihuse y'inyungu nsangira n'abashinzwe imari n'umutungo (CFOs)

Ikiguzi cy'inyongera cya SPDs: €3,500

Igihombo giteganijwe cyo kwiyongera kw'inyongera kidafite SPDs: €50.000 buri myaka 3

Kwishyura: 3.500 ÷ (50.000 ÷ 3) = 0.21 umwaka ≈ amezi 2.5

Nyuma y'ibyo, uruganda rutanga amayero 47.500 buri myaka itatu.

Uburinzi bw'ingufu zidasanzwe ugereranije n'ingufu zisanzwe: Itandukaniro ni irihe ku bucuruzi?

Ndatungurwa iyo mbonye amashanyarazi ya £3 arinda seriveri 30.000; zitanga amasoko y'inyongera gusa, nta gufunganya nyako.

SPD nyazo zikoresha varistors za metal-oxide n'imiyoboro ya gaze kugira ngo zitware ingufu, ntabwo zigacamo ibice gusa.

Imbonerahamwe yo kugereranya impande n'impande

Ikinyuranyo cya €23 ni munsi y'isaha imwe yo kuruhuka.

Impamvu abaguzi bagihitamo ibicuruzwa bitari byo

Abaguzi bakunze kwitiranya "uburinzi bw'umutwaro mwinshi" n' "uburinzi bw'umuraba".

Gushyiramo umuriro mwinshi bihagarika inkongi z'umuriro ziturutse kuri ampli nyinshi; ntacyo bimarira imitsi ya 3 kV.

Nohereje igitabo cy'amashusho cy'urupapuro rumwe kugira ngo amakipe agura abashe gutanga amakuru ku bahanga mu by'amashanyarazi mu minota itanu.

Inama yanjye: koresha ibara ry'amabara

Ncapa ibirango by'umuhondo kuri SPDs n'ubururu ku mirongo y'ibanze. Abakozi bashinzwe kubungabunga bashobora kugenzura itsinda ry'abashinzwe kubungabunga ibidukikije mu masegonda make no kugabanya uburinzi mbere y'igihe cy'inkubi y'umuyaga gitaha.

Ni gute ibikoresho byo kurinda amashanyarazi bishobora kongera igihe cyo kubaho kw'ibikoresho byawe by'amashanyarazi?

Nakurikiranye VFD 200 mu nganda eshanu z'imyenda; ibice biri inyuma ya SPD byamaze imyaka 8.4, ibyo nta myaka 5.1 gusa.

Uduce duto twa buri munsi twangiza ubushyuhe bw'amashanyarazi; SPDs zirya ibyo bintu bito kandi zigatuma moteri zikomeza kubaho.

Imibare y'imihangayiko ya Dielectric ushobora kwereka injeniyeri wawe

Buri gipimo kiri hejuru ya kV 1 kigabanya ubuzima bwacyo mo kabiri. SPD zigumana igipimo kiri munsi ya kV 0.7.

Amafaranga yo kubungabunga yagabanutse

Imoteri yo gusubiza inyuma ya 15 kW igura €900 hamwe n'amasaha abiri yo gukora.

Iyo SPDs zikubujije gusubira inyuma kabiri mu myaka icumi, uzigama €1,800 kuri buri moteri.

Gabanya moteri 50 hanyuma uzabona ubuntu bwo gukoresha amafaranga 90.000 € kuri capex aho kuyisana.

Akamaro kahishe: ububiko buhamye bwa PLC

Ukwiyongera kwa micro-surges gutera bit flips zifunga PLC muri fault mode.

Nyuma yo gushyira ubwoko bwa gatatu bwa SPD ku murongo w’amacupa wo mu Bufaransa, ku wa gatanu nijoro, amakosa y’abazimu yagabanutse ava kuri 11 ku kwezi agera kuri zeru. Abakoresha bahagaritse kongera gukoresha umurongo saa mbiri za mu gitondo, bituma bagabanya umushahara w’amasaha y’inyongera n’imihangayiko.

Ese ibikoresho byo kurinda indwara ni ishoramari rimwe cyangwa ni ngombwa?

Ndabwira buri muguzi SPDs nk'amapine: aramba buhoro buhoro, uyagenzura buri mwaka, hanyuma ukayasimbuza iyo umukandara ushize.

Igice cyiza kimara imyaka 5-10, ariko ahantu hakungahaye ku nkuba hashobora gukenera gusimbuzwa nyuma yo gukubitwa cyane.

Ibipimo by'iherezo ry'ubuzima ugomba kureba

LED y'icyatsi kibisi irazimye = simbura ubu.

Raporo za TUV zigaragaza ko 70% bya SPD zananiwe ziracyakoresha ingufu, bityo abakoresha bibwira ko bafite umutekano mu gihe uburinzi butakiriho.

Nkongeraho ikarita y'ubuntu yoroshye imenyesha SCADA igihe LED ipfuye; abaguzi babona inzogera mbere y'inkubi y'umuyaga itaha.

Gahunda y'ibiciro ntanga ku kugura

Nubwo wasimbura buri myaka itanu, ikiguzi cya buri munsi ni amasenti 3—ahendutse kurusha ikawa.

Uburyo bwo gukoresha ingengo y'imari nta gutungurwa

Nashyize igiciro mu isanduku ya mbere y'akazi mu gihe cy'amezi 24.

Abaguzi bashobora guteganya ko ibicuruzwa bizatangwa buri gihembwe kugira ngo ibicuruzwa bishya bibe byateguwe neza nyuma y’izamuka ry’ibicuruzwa.

Ibi bihagarika gutwara ibintu mu kirere byihutirwa kandi bigatuma TCO ikomeza guteganya igihe cyo kubitwara.

Umwanzuro

Inkuba imwe ishobora gusibanganya inyungu nyinshi kurusha igihembwe cyawe cyiza.

Gufata SPD zemewe uyu munsi, uryame neza iri joro, hanyuma unyoherereze imeri kugira ngo ubone icyitegererezo cy'ibikoresho ku buntu.
