Tanthauzo la Magetsi la SPD ndi Chifukwa Chake Ndi Lofunika Pa Chitetezo cha Kuthamanga

Nthawi zambiri ndimamva kupsinjika maganizo ndikaona magetsi akugwira ntchito popanda chipangizo choyenera choteteza kutentha chifukwa ndikudziwa kuti kukwera kamodzi kokha kungatseke nyumba ndi mafakitale nthawi yomweyo.

Tanthauzo lamagetsi la SPD ndi chipangizo chomwe chimasuntha ma spikes oopsa amagetsi kupita pansi kotero kuti mafundewo sangawononge zida. Chimateteza makina amagetsi ku mphezi, kusintha kwa ma transient, kusokonezeka kwa gridi, ndi mafunde amkati omwe amachitika tsiku lililonse m'nyumba, m'nyumba zamalonda, ndi m'mafakitale.

Pamene machitidwe amagetsi akuchulukirachulukira, nthawi zonse ndimapeza kuti kumvetsetsa ma SPD ndiye gawo loyamba lomanga dongosolo lodalirika loteteza. Choncho ndiloleni ndifotokoze nkhani iliyonse yofunika m'njira yomveka bwino komanso yothandiza.

Momwe Chitetezo cha 220 Chotetezera Kuwonongeka Chimaletsera Kuwonongeka Pakugwiritsa Ntchito Nyumba ndi Mafakitale

Ndimamva kusasangalala nthawi iliyonse ndikawona makina a 220 V opanda chitetezo choyenera, chifukwa nyumba ndi mafakitale onse ali ndi katundu wovuta womwe ungalephereke mosavuta ngati chiwonjezeko chadzidzidzi chachitika.

Choteteza ma surge cha 220 chimateteza kuwonongeka mwa kuyamwa ndikuwongolera mphamvu yamagetsi yochulukirapo isanafike pazida kapena zida. Chimalimbitsa chingwecho, chimateteza ku mphezi, komanso chimachepetsa ma switching amkati omwe amapezeka m'nyumba ndi m'mafakitale.

Ndikamagwira ntchito ndi oyang'anira kugula zinthu kapena mainjiniya amagetsi, nthawi zambiri ndimafotokoza kuti makina a 220 V ndi amodzi mwa magetsi omwe amapezeka kwambiri padziko lonse lapansi. Izi zikutanthauzanso kuti ndi amodzi mwa malo osavuta kwambiri olephera magetsi ngati Chipangizo Choteteza Kuwonjezeka palibe. Ndaona mafakitale akutaya mainjini, ma PLC, ndi masensa chifukwa chongodalira kwambiri gridi.

Mu ntchito za m'nyumba, ogwiritsa ntchito ambiri amaganiza kuti mphezi yokha ndi yomwe imayambitsa kuwonongeka. Komabe, ndayesa machitidwe ambiri ndipo ndapeza kuti 80% ya mikwingwirima yeniyeni imachokera mkati mwa nyumbayo—choyambitsidwa ndi ma air conditioner, mapampu, ndi mafiriji omwe amayatsa ndi kuzimitsa. Choteteza cha 220 surge protector chosavuta chimachepetsa kukwera kwamkati kumeneku ndikusunga zida zogwirira ntchito kukhala zotetezeka.

Mu mafakitale, mphamvu ya ma surge imakhala yamphamvu kwambiri chifukwa katunduyo ndi wolemera kwambiri. Ma mota, ma induction heater, ndi zida zowotcherera zimapanga switching transients zazikulu kwambiri. Chifukwa chake nthawi zonse ndimalimbikitsa SPD ya mafakitale ndi chiwongola dzanja chapamwamba pa malo ogwirira ntchito, zipinda za CNC, kapena mafakitale ang'onoang'ono omwe amagwiritsa ntchito mizere ya 220 V.

Nayi kufananiza mwachidule komwe ndimagwiritsa ntchito nthawi zambiri pophunzitsa akatswiri atsopano:

Tebulo losavuta ili limathandiza ogula kusankha mtundu woyenera mwachangu ndikupewa kugwiritsa ntchito ndalama mopitirira muyeso kapena chitetezo chochepa.

Kumvetsetsa Chitetezo cha Kuwonjezeka mu Chisipanishi kwa Ogwiritsa Ntchito Padziko Lonse

Nthawi zonse ndimamva kuti ndine wodalirika pothandiza makasitomala olankhula Chisipanishi, chifukwa kufotokozera momveka bwino kumatsimikizira kuti amasankha chitetezo choyenera cha mafunde m'mafakitale kapena m'nyumba.

Chitetezo cha mafunde m'Chisipanishi chimafotokozedwa pogwiritsa ntchito mawu monga "dispositivo de protección contra sobretensiones (SPD)" ndi "pararrayos," omwe amafotokoza momwe chipangizochi chimasinthira ma voltage okwera kwambiri ndikuteteza makina amagetsi m'malo okhala, amalonda, ndi mafakitale.

Chifukwa kampani yanga imatumiza kunja Chipangizo Choteteza Kuwonjezeka Zinthu zomwe zimaperekedwa ku Spain, Mexico, Chile, ndi misika ina yolankhula Chisipanishi, ndinaphunzira kuti ogula ambiri amavutika ndi kusiyana pakati pa “SPD,” “protector contra sobretensiones,” ndi “pararrayos.” Kotero nthawi zonse ndimagawa m'mawu osavuta.

Mu Chisipanishi, mawu onse aukadaulo ndi awa:
Chipangizo Choteteza Kuthamanga (SPD)
Izi zikutanthauza chipangizo chomwecho choteteza mafunde chomwe chimagwiritsidwa ntchito padziko lonse lapansi.

Kumbali ina, mawu akuti ndodo ya mphezi nthawi zambiri amatanthauza choletsa mphezi chakunja, osati SPD mkati mwa nyumbayo. Ogula ambiri amasakaniza mawu awa, kotero nthawi zonse ndimafotokozera kusiyana kuti atsimikizire kuti ayika zida zoyenera.

Nayi tebulo losavuta lofotokozera zinthu m'zilankhulo ziwiri lomwe ndikugawana ndi oyang'anira kugula zinthu padziko lonse lapansi:

Ndikamafotokoza za chitetezo cha ma surge pogwiritsa ntchito chilankhulo chawo, makasitomala amakhulupirira kwambiri njira imeneyi. Izi zimathandiza kupewa kusagwirizana kwa ma specifications, chimodzi mwa zinthu zomwe zimawavuta kwambiri ogula padziko lonse lapansi.

Chifukwa chiyani ABB Woteteza Wokwera Amadalira makina amphamvu a mafakitale

Ndimadzidalira ndikawona choteteza cha ABB surge mu gulu la mafakitale chifukwa khalidwe lake la kapangidwe ndi miyezo yoyesera ikukwaniritsa ziyembekezo za mafakitale opanga padziko lonse lapansi.

Chitetezo cha ABB surge ndi chodalirika chifukwa chimapereka mphamvu yolimba yosamalira mafunde, kutsekedwa kwa kutentha kodalirika, ziphaso zapadziko lonse lapansi, komanso kukhazikika kwa nthawi yayitali komwe ogwiritsa ntchito mafakitale amadalira kuti ateteze zida zobisika.

Nthawi iliyonse oyang'anira kugula zinthu akamayerekeza mitundu yosiyanasiyana ya mafakitale a SPD, nthawi zonse ndimaona kuti ABB imawonekera nthawi zonse pamndandanda wawo waufupi. Chifukwa chake n'chosavuta: mtunduwo uli ndi mbiri yayitali pakugawa mphamvu, ndipo ma SPD ake amatsatira miyezo yoyesera kwambiri.

Koma ndikufotokozanso kuti ABB si njira yokhayo yoyenera—mabizinesi monga leikexing (kampani yanga) imapereka zipangizo zogwira ntchito bwino pamtengo wopikisana kwambiri, zomwe ndizofunikira kwa makampani omwe amayang'ana kwambiri kuchepetsa TCO. Komabe, udindo wa ABB pamsika umathandiza makasitomala kumvetsetsa momwe "ubwino wabwino" umaonekera.

Umu ndi momwe ABB nthawi zambiri imafananira ndi ogulitsa ena:

Ngakhale ogula akasankha mtundu wanga, nthawi zonse ndimawalimbikitsa kugwiritsa ntchito mulingo wa magwiridwe antchito a ABB ngati muyezo. Zimasunga ziyembekezo zomveka bwino ndipo zimathandiza kumanga chidaliro cha nthawi yayitali pakati pa ogulitsa ndi makasitomala.

Pamene Chitetezo cha Kuthamanga kwa Voltage Chapamwamba Chikufunika Pa Zida Zolemera

Nthawi zonse ndimakhala wosamala ndikawona ma mota amphamvu kapena ma transformer akugwira ntchito popanda chitetezo chokwanira cha surge chifukwa mphamvu ya surge pamlingo uwu imatha kuwononga zida mumphindi zochepa.

Choteteza mphamvu yamagetsi okwera kwambiri chimafunika pamene zida zolemera zikugwira ntchito kuposa milingo yokhazikika yamagetsi otsika ndipo zikukumana ndi zoopsa kuchokera ku mphezi, kusintha kwa transformer, kuyambika kwa mota, ndi kusokonezeka kwa gridi komwe kumaposa mphamvu ya SPD yachibadwa.

Ndikamayenda m'mafakitale achitsulo, m'migodi, kapena m'mafakitale omwe amagwiritsa ntchito mphamvu zambiri, chinthu choyamba chomwe ndimayesa ndi gawo lomwe limabwera ndi mphamvu zambiri. Pa milingo iyi—3 kV, 6 kV, 10 kV, kapena kupitirira apo—mphamvu ya surge ndi yamphamvu kwambiri. SPD yachibadwa singathe kuigwira.

Zipangizo zolemera monga ma compressor, mapampu akuluakulu, ma elevator, ndi makina ophwanya amapanga ma switching surges amkati omwe amabwerera m'dongosolo. Popanda choletsa ma surge amagetsi amphamvu, ma spikes awa amawononga pang'onopang'ono kutentha kwa zinthu ndikuchepetsa nthawi ya moyo wa chipangizocho.

Nthawi zambiri ndimapereka malamulo atatu osavuta posankha ngati mukufuna SPD yamagetsi amphamvu:

1. Ngati mumagwiritsa ntchito injini zoposa 100 HP — inde

2. Ngati mphezi ikuwonekera kwambiri — inde

3. Ngati nthawi yopuma imatenga ndalama zambiri kuposa chitetezo — inde ndithu

Malamulo osavuta awa amathandiza oyang'anira kugula zinthu kuti atsimikizire chisankhocho mwachangu.

Kusankha Chipangizo Choyenera Choteteza Kuphulika kwa Magetsi

Nthawi zonse ndimakhala ndi chidaliro kwambiri pamene SPD mkati mwa gululo ikugwirizana ndi kapangidwe ka makina, chifukwa kusankha kolakwika kungafooketse unyolo wonse woteteza.

Chipangizo choyenera choteteza ku mafunde amagetsi chimasankhidwa potengera kuchuluka kwa ma voltage, kalasi ya SPD, mphamvu ya mafunde amagetsi, ndi malo oyika. Izi zimatsimikizira kuti gululo limatha kuyamwa ma spikes ndikuteteza katundu wotsatira m'madzi mosamala komanso modalirika.

Pomanga kapena kuwunikanso mapangidwe a mapanelo, nthawi zonse ndimayamba ndi mfundo zoyambira: momwe gridi ilili, mtundu wa zida, ndi mbiri ya zolakwika. Zinthu izi zimandithandiza kusankha kalasi yabwino kwambiri ya SPD.

Mwachitsanzo:

• Kalasi Yoyamba kwa machitidwe omwe amakhudzidwa ndi mphezi kapena akunja

• Kalasi Yachiwiri kwa mapanelo ambiri amagetsi a mafakitale

• Kalasi Yachitatu pa zipangizo zodziwikiratu monga makompyuta ndi ma PLC

Ndimakondanso ma SPD okhala ndi ma module osinthika, chifukwa amachepetsa nthawi yokonza komanso amachepetsa ndalama zomwe zimagwiritsidwa ntchito kwa nthawi yayitali. Izi ndizofunikira kwambiri kwa ogula ngati Jeff, omwe amasamala za kutumiza kodalirika, khalidwe lokhazikika, komanso TCO yotsika.

SPD yosankhidwa bwino imasintha gulu lamagetsi kukhala chingwe choteteza champhamvu, kuchepetsa kulephera ndikusunga chingwe chopangira chikugwira ntchito popanda kusokoneza.

Mapeto

Njira yodalirika yotetezera zida zamagetsi, imachepetsa nthawi yogwira ntchito, komanso imasunga makina onse amagetsi akugwira ntchito bwino—choncho sungani ndalama zotetezera zida zamagetsi zamagetsi zisanakwere.
