Kodi Zipangizo Zoteteza Kuwonjezeka Ndi Zofunikira?

Ndikukumbukirabe tsiku lomwe mphezi imodzi inagunda kasitomala wanga ndalama zokwana €180,000 mu PLC zokazinga.

Ine ndimayang'anira fakitale ya zida zoyeretsera ma surge ya 2,000 m² ku Wenzhou, ndipo ndikukuuzani: Ma SPD Sikuti amakakamizidwa mwalamulo kulikonse, koma ngati muwasiya, mumatchova njuga ndi nthawi yopuma, zopempha za inshuwaransi, komanso mbiri yanu.

Pansipa ndikukufotokozerani mafunso asanu omwe woyang'anira kugula aliyense amandifunsa asanayike oda ya B2B.

Chifukwa chiyani Zipangizo Zoteteza Kuwonjezeka Kodi Ndi Ofunika Kwambiri pa Zomangamanga za Bizinesi Yanu?

Ndikuona mafakitale akutaya 3-5% ya phindu la pachaka chifukwa cha kuwonongeka kwakukulu komwe kumawononga €19 SPD akanatha kusiya.

Mphamvu yochokera ku mphezi, kusintha kwa magetsi, kapena ma mota akuluakulu imagunda 6 kV mkati mwa makabati; popanda ma SPD mphamvuyo imasungunula ma drive, ma seva, ndi masensa.

Kodi kukwera kwa mpweya ndi chiyani kwenikweni ndipo kumachokera kuti?

Kukwera kwa mphamvu ndi kuphulika kochepa kwa mphamvu yamagetsi yomwe imatenga masekondi ang'onoang'ono koma imakhala ndi ma amps mazana ambiri.

Magwero akunja: mphezi, kusinthana kwa gridi, mizere yotsika.

Magwero amkati: Ma VFD, maloboti olumikizira zitsulo, ma HVAC motors akuluakulu, ma elevator.

Ndinalemba mafunde mkati mwa holo yogulitsira zinthu ku Germany kwa sabata imodzi. Tinayesa mafunde 42 pamwamba pa 1 kV; lalikulu kwambiri linafika 3.8 kV. Palibe lomwe linachokera ku mphepo yamkuntho—kukwera kulikonse kunachokera ku makina omwe anali mkati mwa nyumbayo.

Ndalama zobisika zomwe mumalipira mukadumpha ma SPD

Onjezani mizere iyi ndipo ndalama ya €19 SPD ikuwoneka yotsika mtengo.

Miyezo yomwe imakukakamizani kukhazikitsa ma SPD

IEC 60364-4-44 ndi NFPA 70 onse amati: ngati zotsatira za kukwera kwa galimoto ndi moto, kuvulala, kapena kuzimitsidwa kwa machitidwe otetezera moyo, muyenera kukhala ndi chitetezo cha kukwera kwa galimoto.

Mu EU, EN 50550-2023 yatsopano imapangitsa kuti ma SPD akhale ofunikira pa nyumba za anthu onse komanso malo osungira deta.

Ngakhale pamene malamulowo ali chete, makampani a inshuwalansi tsopano amalemba kuti "chivundikiro cha surge pokhapokha ngati SPD yayikidwa" mu ndondomeko za fakitale.

Ndimathandiza ogula kusankha zinthu mwa kutumiza malipoti a mayeso kuchokera ku labu yathu yovomerezeka ndi TUV; mapepalawo amasangalatsa dipatimenti yawo yoona za zoopsa.

Kodi Zipangizo Zoteteza Kuwonjezeka Kwakanthawi Zingateteze Bwanji Bizinesi Yanu Ku Zowonongeka Zokwera Mtengo?

Ndinaonera chidebe cha shrimp yozizira cha mamita 40 chikusungunuka chifukwa cha kukwera kamodzi komwe kunapha PLC yoziziritsa; SPD ya €35 ikanapulumutsa katundu wa €200,000.

Ma SPD amaletsa kukwera kwa galimoto asanafike pazigawo zovuta, zomwe zimachepetsa ndalama zosinthira ndi nthawi yopuma ndi 90%.

Ndondomeko yodzitetezera ya magawo atatu yomwe ndimapatsa wogula aliyense

Ndimatumiza mitundu yonse itatu kuchokera ku Wenzhou kuti ogula athe kugula kamodzi kokha ndikupewa mavuto osiyanasiyana.

Nkhani yeniyeni: fakitale yamagalimoto ku Birmingham

Anakwera mtundu woyamba wokha pa munthu wopeza ndalama. Mphamvu inakwera pa basi ndipo inapha maloboti atatu a KUKA.

Tinawonjezera mayunitsi a sitima yamtundu wa II DIN pafupi ndi kabati iliyonse. Patatha chaka chimodzi mphepo yamkuntho inagwa; maloboti anakhalabe ndi moyo, zomwe zinapulumutsa £120,000 m'zigawo ndi maola 18 osagwira ntchito.

Fomula yachangu ya ROI yomwe ndimagawana ndi ma CFO

Mtengo wowonjezera wa SPDs: €3,500

Kutayika kwa surge komwe kumayembekezeredwa popanda SPDs: €50,000 zaka zitatu zilizonse

Kubwezera: 3,500 ÷ (50,000 ÷ 3) = 0.21 chaka ≈ miyezi 2.5

Pambuyo pake fakitaleyo imasunga €47,500 pazaka zitatu zilizonse.

Chitetezo cha Kuthamanga Kwambiri vs. Mphamvu Zamagetsi Zachizolowezi: Kodi Kusiyana Kwa Mabizinesi N'kutani?

Ndimanjenjemera kwambiri ndikaona zida zamagetsi zokwana £3 zikuteteza ma seva okwana £30,000; zimangopereka ma soketi owonjezera, palibe zomangira zenizeni.

Ma SPD enieni amagwiritsa ntchito ma varistor a metal-oxide ndi machubu a gasi kuti atenge mphamvu, osati kungoigawa.

Tebulo loyerekeza mbali ndi mbali

Kusiyana kwa €23 ndi nthawi yochepera ola limodzi yopuma.

Chifukwa chiyani ogula amasankhabe chinthu cholakwika

Ogula nthawi zambiri amasokoneza "chitetezo chowonjezera katundu" ndi "chitetezo chowonjezera katundu".

Kuchuluka kwa mphamvu kumaletsa moto chifukwa cha ma amp ambiri; sikuthandiza chilichonse pa ma spikes a 3 kV.

Ndimatumiza chitsogozo cha zithunzi cha tsamba limodzi kuti magulu ogula zinthu athe kuuza akatswiri awo amagetsi mumphindi zisanu.

Malangizo anga: gwiritsani ntchito kulemba mitundu

Ndimasindikiza zilembo za lalanje za SPDs ndi buluu za mizere yoyambira. Ogwira ntchito yokonza amatha kuyang'ana gululo m'masekondi ochepa ndikupeza chitetezo chomwe sichinapezeke nyengo yamkuntho isanafike.

Kodi Zipangizo Zoteteza Kuthamanga Kwambiri Zingawonjezere Bwanji Moyo wa Zipangizo Zanu Zamagetsi?

Ndinatsata ma VFD 200 m'mafakitale asanu opangira nsalu; mayunitsi omwe anali kumbuyo kwa ma SPD adatenga zaka 8.4, omwe analibe zaka 5.1 zokha.

Kukwera pang'ono kwa tsiku ndi tsiku kumawononga chitetezo chamthupi; ma SPD amadya zinthu zazing'ono zomwe zimachitika ndipo amasunga ma mota amoyo.

Manambala a kupsinjika kwa dielectric omwe mungawawonetse mainjiniya anu

Kukwera kulikonse kopitilira 1 kV kumachepetsa moyo wa chipangizocho ndi theka. Ma SPD amasunga nsonga pansi pa 0.7 kV.

Ndalama zokonzera zasungidwa

Kubwezeretsa injini ya 15 kW kumawononga €900 kuphatikiza ntchito ya maola awiri.

Ngati ma SPD aletsa kubwerera m'mbuyo kawiri pazaka khumi, mumasunga €1,800 pa mota iliyonse.

Chulukitsani ndi ma mota 50 ndipo mumapereka ndalama zokwana €90,000 pa capex m'malo mokonza.

Ubwino wobisika: kukumbukira kokhazikika kwa PLC

Ma micro-surges amachititsa kuti ma bit flips atseke ma PLC mu fault mode.

Titayika ma SPD a Mtundu wa III pa chingwe cha mabotolo cha ku France, zolakwika za Lachisanu usiku zinatsika kuchoka pa 11 pamwezi kufika pa zero. Ogwira ntchito anasiya kuyambitsanso chingwe nthawi ya 2 koloko m'mawa, zomwe zinapulumutsa malipiro ndi nkhawa pa nthawi yowonjezera.

Kodi Zipangizo Zoteteza Kuwonjezeka Ndi Ndalama Yokhazikika Kapena Ndi Yofunikira Kwambiri?

Ndimauza wogula aliyense kuti ma SPD ali ngati matayala: amawonongeka pang'onopang'ono, mumawayang'ana chaka chilichonse, ndipo mumawasintha akachoka.

Chipangizo chabwino chimatenga zaka 5-10, koma malo okhala ndi mphezi angafunike kusinthana pambuyo poti chagunda kwambiri.

Zizindikiro za mapeto a moyo zomwe muyenera kuziyang'anira

LED yobiriwira yazimitsidwa = sinthani tsopano.

Malipoti a TUV akusonyeza kuti 70% ya ma SPD omwe alephera amapitilirabe kugwiritsa ntchito mphamvu, kotero ogwira ntchito amaganiza kuti ali otetezeka pomwe chitetezo sichinathe.

Ndimawonjezera khadi laulere lokhala ndi chizindikiro cha SCADA pamene LED yafa; ogula amalandira alamu mphepo yamkuntho isanayambe.

Ndondomeko ya mtengo yomwe ndimapereka kwa ogula

Ngakhale mutasintha zaka zisanu zilizonse, mtengo wa tsiku ndi tsiku ndi masenti atatu—wotsika mtengo kuposa khofi.

Momwe mungapangire bajeti popanda zodabwitsa

Ndatseka mtengo mu PO yoyamba kwa miyezi 24.

Ogula akhoza kukonza nthawi yotumizira katundu kotala lililonse kuti katundu watsopano akhale pashelefu yawo, okonzeka pambuyo pa chochitika cha kuchuluka kwa katundu.

Izi zimaletsa kunyamula katundu wa ndege mwadzidzidzi ndipo zimapangitsa kuti TCO izidziwike.

Mapeto

Mphezi imodzi imatha kuchotsa margin ambiri kuposa gawo lanu labwino kwambiri.

Khalani ndi ma SPD ovomerezeka lero, gonani bwino usikuuno, ndipo nditumizireni imelo kuti mupeze zitsanzo zaulere.
