Chii chinonzi Basa reMudziviriri weKuputika?

Ndichiri kurangarira zuva iro mheni imwe chete yakarova mutengi wangu nemutengo wehafu yemiriyoni yemadhora. Kamwe chete, rack yake yese yePLC yakashanduka kuita simbi yakachekwa inodhura.

Chidziviriro chemagetsi chinotsausa kana kunyudza ma voltage spikes ane njodzi asati asvika kumidziyo inokuvadza, kuitira kuti michina yako, data, uye purofiti zvirambe zvakachengeteka. Ndakaona mudziyo uyu uri nyore uchichengetedza mitsetse yese yekugadzira muChina, Germany, neUK.

Kana ukatenga zvishandiso zvekudzivirira dunhu Kuti urarame, unotoziva kuti mitengo inokosha. Ramba uchiverenga uye ndichakuratidza maitiro ekuderedza mari yese yekuva muridzi pasina kuderedza dziviriro.

Kunzwisisa Sdziviriro yekukurudzira munzvimbo dzemaindasitiri nedzekutengeserana?

Ndakafamba nepakati pefekitori yemotokari inoshanda maawa makumi maviri nemana muWenzhou mwedzi wapera. Maneja akandiudza kuti awa yega yega yekushanda inodhura 38,000 USD. Kukwira kamwe chete kunogona kukonzera kushanda ikoko mumasekonzi matatu.

Dziviriro yekushandiswa kwemaindasitiri inomisa over-voltages dzinobva mumagetsi anogadzirwa nemheni, grid switching, uye Variable Frequency Drives kuti dzisasvike kumaPLC, maserver, nemarobhoti. Ndinogadzira masisitimu aya emigwagwa yemotokari yekuGermany nenzvimbo dzedata dzekuBritain vhiki rega rega.

Ungafunga kuti kukwira kwemvura kunongova pfari inopenya. Chokwadi chine njodzi, uye chakachipa kumisa pane kugadzirisa.

Kwakabva mafungu

Mheni ndiyo inonyanya kurira, asi haisi iyo inonyanya kuoneka. Ndinoyera maspikes akawanda kubva mukati kupfuura kubva mudenga. Kudzima mota ye100 hp kunogona kudzosa 1,800 V mubhazi rimwe chete rinopa sensor yako. Kukwira uku kunotora 50 microseconds chete, asi kwenguva yakareba zvakakwana kuti iboore gate oxide yeMOSFET. Ndakaona izvi mufekitori yekurongedza yeVietnamese. Takawedzera 40 kA Type 2 protector panel, uye failure rate yakaderera kubva pamabhodhi matatu pamwedzi kusvika zero mumwedzi gumi nemana.

Njodzi yacho yakakura sei?

Ndakakumbira timu yangu kuti itore data kubva kumafekitori mazana maviri atinoshandira. Takaona kuti nzvimbo isina dziviriro yekuputika kwemagetsi inosangana nekuvharwa kusina kurongwa ka7.4 pagore. Kuvharwa kwega kwega kwemagetsi kunosvika maawa 4.2. Kana mari yako iri 50 k USD pazuva, zvinoreva 1.5 miriyoni USD yekuratidzwa kwemagetsi gore rega rega. Chidziviriro chefekitori yese chinodhura zvishoma pane 0.3% yenhamba iyoyo. Nguva yekubhadhara imazuva gumi nerimwe, kwete mwedzi gumi nerimwe.

Mitemo yaunofanira kusangana nayo

Ndinotumira kuEurope, saka zvese zvinodzivirira zvandinotengesa zvine zvakanyorwa neCE neTÜV. Tinoedza zvinoenderana neIEC 61643-11. Kana ukatumira kuGermany, unodawo VDE 0675. Ndinochengeta mafaira iwayo muChirungu nechiGerman, akagadzirira kuforodha yako yekupa chitupa. Unogona kuatumira kumutengi wako wekupedzisira pazuva rimwe chete raunogamuchira zvinhu.

Mabasa Ekutanga eMudziviriri weKuputika?

Kota yapfuura ndakabatsira kambani yekubika chingwa neautomation yekuFrance. Vakatumira tambo itsva kuCanada, uye bvunzo yekutanga yekuvhiya yakakundikana. Takawedzera module yedu ye plug-in, uye system yakapasa mangwanani akatevera.

Chinodzivirira mhepo chinobuda nemhepo chinonzwa magetsi akawandisa, chinochisunga kusvika padanho rakachengeteka, uye chobva chazvigadzirisa kuti kugadzirwa kuenderere mberi pasina kupindira nemaoko.Ndinoedza midziyo yese pajenareta yedu yemagetsi ye8/20 µs isati yabuda padoko redu reWenzhou.

Ungafunga kuti michina yekusukira mabhokisi esimbi akareruka. Mukati, zvidimbu zvitatu zvidiki zvinosarudza kana tambo yako ichishanda kana kutsva.

Kutamba kwematanho matatu

Ndinogara ndichitsanangura basa iri nematanho matatu. Danho rekutanga: gas arrester inotora kurova kwekutanga. Inopfuta pa600 V uye inogadzira short. Danho rechipiri: metal-oxide varistor (MOV) inotora simba rakawanda. Danho rechitatu: TVS diode inocheka 30 V yekupedzisira kuitira kuti 24 V PLC yako isaone kupfuura 37 V. Ndakatarisa izvi pabhenji redu rekurabhoritari. Chiitiko chose chinopera mumasekonzi mapfumbamwe, nekukurumidza kupfuura HMI yako inogona kupenya.

Chinodzikisa kupisa

MOV dzinokura. Kana MOV ikakundikana, inogona kudzima moto wobva wabatira moto. Ndinoisa fuse inodziya yakasungirirwa mumuviri weMOV. Pa142 °C fuse inovhurwa yodhonza MOV isina kudzima. Ndine mapikicha ebvunzo eUL 1449 4th edition anoratidza kuti hapana moto mushure memaminitsi makumi matatu. Inishuwarenzi yenyu yemoto ichafarira faira iroro.

Kubata uri kure

Mafekitori makuru anoda kuziva kuti chidziviriro chafa chisati chasvika. Ini ndinowedzera chinhu chisingashande. Unogona kuchiisa kuSCADA yako. Kana chidziviriro chikakundikana, PLC yako inowana chiratidzo che24 V uye unoronga kuchinjana panguva yekumira kunotevera kwakarongwa. Hapana kufona pakati pehusiku, hapana kumhanyisa kutakura zvinhu.

Sei Kudzivirirwa Kwekukwira Kwemhepo Kuchikosha Kumabhizinesi?

Ndakarasikirwa nemutengi wekuUK muna 2019. Akasiya maprotectors kuti achengetedze 2,300 USD. Dutu rakarova, rakaparadza madhiraivha gumi nemasere, uye inishuwarenzi yake yakaramba chikumbiro chacho. Akavhara fekitori mwedzi miviri gare gare.

Dziviriro yekuwedzera kwemari inoita kuti mari irambe ichibuda, vimbiso dziri kushanda, uye mukurumbira wekambani iyi hauna kukanganiswa.Ndine tsamba dzinobva kuvatungamiriri vezvemari vanotiti magamba, kwete vatengesi.

Unogona kutevedzera mutengo payuniti imwe neimwe. CFO wako anotevedza EBITDA. Kuwedzera kamwe chete kunogona kubvisa mari yawakachengeta kwemakore gumi.

Mari dzakavanzwa dzaunokanganwa

Kana dhiraivha ikakundikana, unobhadhara chikamu, technician, crane, uye batch yakarasika. Ndinozvinyora mupepa riri nyore remutengo wega wega. Dhiraivha ye75 kW inodhura 4,800 USD. Crane inodhura 600 USD. Kurasikirwa kwebatch i12,000 USD. Huwandu hwese i17,400 USD. Chidziviriri changu chinodhura 89 USD. Masvomhu haana kunaka, asi ndeechokwadi.

Mitemo yewarandi

Ndinopa waranti yemakore mashanu pamudziviriri wega wega, asi chete kana ukatevera IEC 60364-5-53 woiisa mupanera rekurudyi. Kana ukadarika dziviriro, waranti yako yeOEM padhiraivha inogona kusashanda. Ndakaona Siemens ichiramba chikumbiro che25 k USD nekuti saiti yacho yakanga isina SPD. Mutengi akatipa mhosva, asi mhosva yaive sarudzo yake.

Inishuwarenzi yepamusoro

Ndinoshanda nekambani yeinishuwarenzi yekuGermany inopa 5% kubva pamari yeprimiyamu kana fekitori ine maSPD akanyoreswa padanho rega rega. Pamutemo we400 k USD unochengetedza 20 k USD gore rega rega.

Unganzwa wakarasika pakati pemazita emhando ye1, 2, uye 3. Ndaderedza ruzha ndokukupa mibvunzo mitatu.

Mubvunzo 1: Mheni iri kupi?

Ndinovhura Google Maps ndotarisa huwandu hwemheni. Kana fekitori yako iri munzvimbo ine ma flashes mana/km² pagore, unoda Type 1 pagedhi rebasa. Kana uri pasi pe 0.5 flashes, Type 2 yakakwana. Ndinochengeta mepu yepasi rose ine data iri. Ndinoitumira mahara nemutengo wega wega.

Mubvunzo 2: Ndeipi short-circuit current yako?

Ndakaverenga nameplate yenyu yetransformer. Transformer ye1,600 kVA inopa 35 kA fault current. Chidziviriri changu chinofanira kurarama nacho. Ini ndinosarudza unit ine 50 kA SCC rating. Kana ukatenga mudziyo we15 kA kuti uchengetedze 12 USD, ichaputika panguva yekukanganisa kwekutanga. Ndine mapikicha, uye haana kunaka.

Mubvunzo 3: Unoda plugable here?

Vamwe vatengi havadi kuti zvinhu zvisashande. Ini ndinopa katuriji inogona kubhurwa. Kana module ikakundikana, unoichinja mumasekonzi mapfumbamwe. Hapana sikurudhiraivha, hapana waya itsva. Fekitori inoramba ichishanda. Module yekusara inodhura 28 USD. Kuchinja kamwe chete kunochengetedza mari yakawanda kupfuura iyoyo panguva yekusashanda.

Mafambiro Emangwana muKudzivirira Kuputika Kwekombiyuta?

Ndakamira pachikuva cheHannover Messe munaKubvumbi wadarika ndikamuratidza mudziyo wekudzivirira une QR code. Vateereri vakaseka, kusvika ndauongorora ndikaona data riripo pachiratidziro.
