Chinangwa cheMudziviriri weKuputika ndechei?
Ndichiri kurangarira kunhuhwirira kwebhodhi remadhora zviuru zvipfumbamwe rePLC raitsva mushure mekurohwa kamwe chete—chikamu chimwe chete chakachipa chaigona kurichengetedza.
Chidziviriro chemagetsi chinotora simba rakawanda, chobva chazvisundira pasi kuitira kuti michina yenyu igare yakachengeteka. Ndinovaka mayuniti aya zuva nezuva muWenzhou uye ndinoedza imwe neimwe maererano neIEC 61643-11.
Kana uchiziva kuti nei mafungu achibuda uye kuti bhokisi diki rinoamisa sei, unogona kusarudza chikamu chakakodzera worega kubhadhara kukuvara kwausina kuronga.
Sei Kudzivirirwa Kwekuvhiyiwa Kunodiwa? Njodzi Nekukuvara Kunokonzerwa Nekuvhiyiwa?
Ndakamboona mheni ichimisa mutsetse wese muMilan—madhiraivha, HMI, uye kunyange muchina wekofi wakafa panguva imwe chete.
Kukwira kwemhepo kunogona kubva mumheni, kuputika kwemhepo, kana mota hombe, uye zvinouraya madhiraivha, mabhodhi, uye data. Kurova kamwe chete kunogona kudhura anopfuura gore rekuchengetedza kukwira kwemhepo.
Kunobva Kupi?
Kukwira kwesimba ipfupi kuputika kwemagetsi akakwira kunotora masekondi mashoma. Mheni ndiyo sosi huru, asi kurova kwakawanda kunobva mukati mefekitori. Kana mota ye100 kW yamira, coil inosundira simba kumashure mumutsara. Spike iyoyo inogona kurova 2 kV uye kufamba netambo imwecheteyo inodyisa PLC yako. Ndinoedza zviitiko zvakadaro vhiki rega rega murabhoritari yangu. Tinobatidza mota, toimisa zvakasimba, uye toona scope ichisvetuka. Kurova kuri pedyo pagrid kunowedzera simba rakawanda. Musanganiswa wezvinhu zvese zviri zviviri ndizvo zvinoonekwa nemuchina wako pazuva redutu.
Zvinoita Kukwira Kwemhepo Kumidziyo Yako
Madhiraivha emazuva ano anoshandisa maMOSFET eV 600 anofa pa900 V. Simba re1.5 kV rinouraya kamwe chete. Mushure mekurovera, madhiraivha mapfupi, fuse inoputika, uye tambo inomira. Basa rinoramba richishanda pamadhora mazana maviri paawa. Mumwe mutengi akarasikirwa nemadhora zviuru makumi matatu nemasere nemazana manomwe emadhora muhusiku humwe chete. Madhiraivha anobikawo insulation mumamota nematransformer. Ungasaona ronda pazuva rekutanga, asi mhangura inoshanduka kuita dema uye chikamu chinokundikana mwedzi mitanhatu gare gare. Kukuvara ikoko kwakavanzika ndiko kunoita kuti vatengi vazhinji vafunge kuti "hazvimboitiki pano" kusvika bhiri radonha.
Tafura yeMari Chaiyo Yandakaona

Tafura inoratidza kuti kunyangwe kumira kwenguva pfupi kunodhura kupfuura SPDs dzese.
Njodzi Yakavanzika: Data uye Kuchengetedzeka
Mafungu anodzima data muPLCs uye trip safety relay. Imwe fekitari yegirazi yakandiudza kuti spike imwe chete yakagadzirisa batch counter, saka furnace yakadurura musanganiswa usiriwo. Girazi raifanira kucherwa nemaoko. Izvi zvakawedzera maawa makumi maviri ekushanda nesimba uye kurasikirwa nemadhora makumi mashanu ezviuru. Kana system yekuchengetedza ikadonha panguva isiriyo, vashandi vanogona kukuvara. Ndinotengesa SPDs nemhangura, asi ndinorara zviri nani kana ndichiziva kuti vanhu vakachengetekawo.
Nei Inishuwarenzi Isina Kukwana?
Vamwe vatengi vanovimba neinishuwarenzi. Inobhadhara mari, asi haidzose vatengi vakarasika. Kana ukarasikirwa nemazuva ekutumira, mutengi wako anowana imwe nzvimbo. Kuramwa kamwe chete kunogona kukutorera chibvumirano chemakore mashanu. SPD inodhura isingasviki awa imwe chete yekuzorora uye inochengetedza bhuku reodha rakazara.
Chinangwa cheMudziviriri weKuputika ndechei? — Basa rekutanga uye Nheyo dzeKushanda?
Ndichiri kunyemwerera pandinoona LED yegirini pane panel—zvinoreva kuti bhokisi diki rakarova uye dhiraivha ichiri kushanda.
Chinodzivirira simba remagetsi chinonzwa simba remagetsi rakawanda, chinotora simba rakawedzerwa, uye chinoritumira pasi mumasekonzi mashoma. Chinosunga tambo kuitira kuti mutoro uone mwero wakachengeteka, uye ndinoedza batch yega yega kusvika ku20 kA muWenzhou.
Mashandiro anoita MOV Basa
Metal-oxide varistor (MOV) idhisiki receramic rinoita seswitch. Pa 230 V rinovhurika uye rinodhonza pasi pe 0.3 mA. Kana mutsetse ukasvetuka pamusoro pe 275 V, dhisiki rinovhara uye resistance yaro inodonha kusvika pasi pe ohm. Surge current inomhanya nemu MOV, kwete kuburikidza ne drive yako. Voltage iri mu drive inoramba iri pedyo ne 700 V, iri pasi pe 900 V danger line. Mushure mekunge surge yapera, MOV inovhura zvakare uye inomirira kurova kunotevera. Ndakaona dhisiki rimwe richitora ma shots makumi maviri nematatu risati raneta.
Nei Kureba kweWaya yePasi Kuchikunda Saizi yeMOV
Vatengi vazhinji vanobvunza kuti "kA yakakura" asi vanokanganwa nezve tambo. Muswe wepasi mupfupi we 25 cm unopa 980 V let-through. Wedzera 55 cm uye let-through inosvetuka kusvika 1,450 V. Dhiraivha inofa kunyangwe MOV yakafanana. Ndinodzidzisa vanoisa kuti vakotamise muswe kamwe chete vousunga zvakananga kuPE bar. Danho iroro rinokunda kubhadhara chikamu che 100 kA.

Gas Discharge Tube Backup
MOV inopera. Chubhu yekuburitsa gasi (GDT) inogona kutora simba rakawanda asi inononoka. Tinoisa waya dzese dziri mbiri panguva imwe chete. MOV inotanga ne25 ns uye inovhara spike yekutanga. GDT inobatidza pa600 V uye inotora simba guru remagetsi kune 100 µs inotevera. MOV inozorora uye inogara kwenguva refu. Tinoti iyi dhizaini yehybrid, uye ikozvino ndiyo yakajairika kune mapurazi ezuva ekuGermany anoda hupenyu hwemakore makumi maviri.
Kudzima Moto Kunodzivirira Moto
Kana MOV yafa, inogona kupfupika yopisa. Chinobatidza chiri mukati meyuniti yedu chinoputika pa120 °C uye chinobvisa chikamu chacho pamutsetse. Chinobatidza chinoenderana neMOV disk, saka chinonzwa kupisa kwakafanana. Ndinochiedza muovheni pa1 °C paminiti. Chinofanira kuvhurika diski isati yatanga kuputa. Chikamu ichocho chesendi chinochengetedza panel nezita rangu.
Chiratidzo Chekure Chemasayiti Akangwara
Mafekitori makuru anoda kuziva izvozvi, kwete mwedzi unouya. Tinowedzera micro-switch inoita kuti pave nekubatana kwakaoma. Kubatana kunopa 24 V PLC. Kana SPD yafa, HMI inoshanduka kuva tsvuku. Mutengi anoraira katuriji yekusara isati yatanga dutu rinotevera. Ndinoitumira zuva rimwe chete uye nguva yekushanda inoderera kubva pamaawa kusvika pamaminitsi.
Ungasarudza Sei Mudziviriri Akakodzera weKuvhiya?
Ndakambotumira chikamu che40 kA kune mumwe murume aida 10 kA chete—iye akabhadhara kaviri asi achiri kuitumidza kuti inishuwarenzi yakachipa.
Sarudza voltage yakaderera yaunogona kutenga, enzanisa simba remagetsi rinouya nenjodzi, uye iva nechokwadi chekuti chikamu chacho chinoenderana nepaneru yako uye maitiro ako ekugadzirisa. Ndinotumira bepa rekunyepedzera rine peji rimwe chete rine mutengo wega wega.
Danho 1: Tsvaga Njodzi Yako
Tarisai panopinzwa magetsi. Mitsetse yepamusoro munzvimbo dzine dutu inoda Type 1. Tambo dzepasi pevhu muhofisi yakachena dzinoda Type 2. Tambo refu dzinoenda kuPLC dzinoda Type 3. Ndinobvunza mibvunzo mitatu: (1) Chivako chakarohwa kare here? (2) Mutoro wacho wakakosha here? (3) Tambo yacho yakareba here? Imwe "hongu" tobva tawedzera kanenge Type 2.
Danho rechipiri: Sarudza Voltage Rating Yakakodzera
Pa 230 V tinoshandisa 275 V max continuous. Pa 480 V tinoshandisa 550 V. Chikamu chakayerwa kuti chakaderera chichapera nekukurumidza. Chikamu chakayerwa kuti chakakwira chichanonoka kuvharwa uye chinoita kuti drive ione mavolts akawanda. Ndinoenzanisa chiyero nemutsetse pamwe ne15% headroom. Izvi zvinoita kuti igare kwenguva refu uye isapinda zvakanyanya.
Danho rechitatu: Enzanisa Surge Current
IEC 62305 inopa mazinga: 25 kA, 40 kA, 60 kA. Hofisi yeguta ine 10–15 kA pagore. Fekitori yegungwa ine 40 kA. Ini ndinotengesa 40 kA sechinotangira kushandiswa mumaindasitiri. Kana nzvimbo yacho iine mwenje, tinowedzera 25 kA Type 1 pabhodhi guru uye 40 kA Type 2 pazvikamu zvidiki. Mutengo wakaderera uye chifukidziro chakazara.

Tarisa Chinonyanya Kukosha paFomu
Mamwe mapaneru akamanikana. Tinopa upamhi hwe18 mm ne36 mm. Kana njanji yakazara, tinopatsanura SPD neDIN rails mbiri kana kushandisa plug-in base kuitira kuti mushandisi atsinhane cartridge chete. Ndinokumbira mufananidzo wepaneru uye ndinomaka nzvimbo dzakasununguka netsvuku. Hapana anoda zvinoshamisa pazuva rekuisa.
Funga Nezvekutsiva
LED yegirini yakanaka kune nzvimbo diki. Kubata kure kuri nani kune hombe. Kana nzvimbo yacho ichishanda maawa makumi maviri nemana pazuva, mazuva manomwe pasvondo, tinowedzera harness ye fly-wire kuitira kuti chikamu chacho chitsiviwe. Mutengo wacho unowedzera nemadhora matatu uye nguva yekushanda haisipo. Jeff anondiudza kuti shift imwe chete yakachengetwa inobhadhara odha yese yeSPD.
Mhedziso
Chidziviriro chemuchina wekudzivirira kumhanya chinodya simba rakawanda uye chinoita kuti tambo yako irambe iri mhenyu. Sarudza tambo yakaderera, enzanisa njodzi, uye unotenga rugare kwenguva isingasviki awa imwe chete yekurega kumhanya.
