Mitundu Yapamwamba ya Chitetezo cha Surge Chipinda Chilichonse Chiyenera Kumvetsetsa

Nthawi zambiri ndimamva kupsinjika ndikawona momwe kukwera kamodzi kokha kungaletsere kupanga, kotero nthawi zonse ndimafunafuna njira yodalirika Chipangizo Choteteza Kuwonjezekakuti akhale otetezeka.

Chipangizo Choteteza Kukwera kwa Mphamvu chimateteza makina amagetsi mwa kusuntha mphamvu yamagetsi yochulukirapo kuchoka pa zida, kuchepetsa mphamvu ya kukwera kwa magetsi komwe kumachitika chifukwa cha mphezi, kusintha kwa zinthu, kapena kusokonezeka kwa gridi. Chimachepetsa kukwera koopsa, chimakhazikitsa dongosolo, komanso chimachepetsa zoopsa zolephera kwa zida, makamaka m'malo opangira mafakitale komwe nthawi yogwira ntchito ndi yofunika kwambiri.

Ndikamalankhula ndi oyang'anira kugula zinthu monga Jeff, ndimadziwa kuti akufuna mayankho omveka bwino komanso zotsatira zodziwikiratu. Chifukwa chake m'nkhaniyi, ndikulongosola mitundu ya chitetezo cha surge chomwe malo aliwonse ayenera kumvetsetsa komanso momwe chilichonse chimagwirira ntchito.

Momwe Dera Lopondereza Kuthamanga Limatetezera Machitidwe Amagetsi

Nthawi zonse ndimada nkhawa ndi ma spikes obisika mkati mwa makina amagetsi, kotero ndimadalira circuit yabwino yopondereza ma surge kuti ndipewe nthawi yotsika mtengo yogwira ntchito pamalo anga.

Chida choletsa mafunde chimateteza magetsi mwa kuyamwa kapena kutumizira magetsi ochulukirapo kudzera m'zigawo monga MOVs, machubu otulutsa mpweya, ndi ma TVS diodes. Chimayendetsa bwino katundu wamagetsi ndikuletsa kukwera mwadzidzidzi kwa zida zobisika m'mafakitale kapena m'mabizinesi.

Ma circuits oletsa kugwedezeka ndi maziko a SPD iliyonse yodalirika yomwe imagwiritsidwa ntchito m'mafakitale. Ndikamayesa mayankho a SPD a mafakitale kwa ogula omwe amasamala za kukhazikika ndi TCO, nthawi zonse ndimayerekeza zigawo zamkati chifukwa zimazindikira nthawi ya moyo ndi nthawi yoyankhira.

Nayi kufananiza kosavuta komwe kukuwonetsa magawo apakati a ma circuits opondereza ma surge:

Popeza ndimakumana ndi malo osiyanasiyana ochitira ma surge m'mafakitale, ndimayang'ananso mphamvu ya clamping voltage ndi maximum discharge current. Izi zimatsimikiza ngati chitetezo cha mafunde amagetsi m'mafakitalendi yolimba mokwanira kuti igwire madera odzaza ndi mphezi kapena ma gridi amagetsi osakhazikika.

M'mafakitale ambiri omwe ndimagwira nawo ntchito, makamaka ku USA ndi India, ndimaona kuti chiopsezo chachikulu ndi mphezi yosalunjika. Izi zikachitika, chopondereza cha MOV chokha chingawonongeke mwachangu. Ichi ndichifukwa chake ogulitsa apamwamba monga leikexing amagwiritsa ntchito kapangidwe kosakanikirana kophatikiza MOV + GDT kuti ntchito ikhale yayitali.

Ndikamathandiza magulu ogula zinthu kuti afufuze ogulitsa, nthawi zonse ndimawalangiza kuti ayang'ane mfundo zitatu izi:

Ndi kapangidwe koyenera ka suppressor, SPD imagwira ntchito bwino, imakhala nthawi yayitali, ndipo imateteza nthawi zonse. Izi ndi zomwe oyang'anira kugula zinthu monga Jeff amaona kuti ndi zofunika kwambiri—kudziwikiratu.Kuti mufufuze zipangizo zoteteza ma surge zamafakitale ndi mapangidwe a hybrid MOV+GDT, mutha kuwona zinthu zathu zoteteza ma surge zamafakitale kuti mudziwe zambiri zaukadaulo.

Momwe Wotetezera Wothamanga Amagwirira Ntchito Poletsa Kuthamanga Koopsa kwa Voltage

Ndaona makina akuyambiranso mwadzidzidzi chifukwa cha kukwera kwa magetsi, choncho ndimagwiritsa ntchito zoteteza ma surge kuti makina anga akhale olimba.

Choteteza mafunde chimagwira ntchito pozindikira kuchuluka kwa magetsi kosazolowereka ndikutumiza mphamvu yochulukirapo nthawi yomweyo ku dongosolo loyikira pansi. Chimachepetsa mphamvu ya mafunde isanafike pazida, kupewa kupitirira muyeso, zoopsa za moto, kapena kuwonongeka kwa mafunde m'mafakitale amafakitale.

Ndikafotokozera ogula izi, ndimalongosola kuti ndi "valavu yotulutsa mphamvu" yamagetsi. SPD imamva kukwera koopsa ndipo nthawi yomweyo imatsegula njira yotetezeka yopita pansi.

Kuti timvetse bwino izi, nayi njira yosavuta yodziwira momwe SPD yamakampani imayankhira:

Ndimayang'ananso magawo atatu akuluakulu nthawi iliyonse ndikasankha choteteza ma surge cha mafakitale:

1.Kutulutsa Kwambiri Kwambiri (Imax)
Zinthu zapamwamba zimatanthauza chitetezo chabwino cha mphezi.

2.Mlingo Woteteza Voltage (Kukwera)
Kutsika mmwamba kumatanthauza zida zotetezeka.

3.Nthawi Yoyankha
Kuyankha mwachangu kumaletsa kuwonongeka pang'ono komwe kumapha pang'onopang'ono ma mota ndi ma PLC.

Malinga ndi zomwe ndakumana nazo, kudalirika kwa nthawi yayitali nthawi zambiri kumadalira kwambiri kasamalidwe ka kutentha kuposa mphamvu yamagetsi yapamwamba. Opanga abwino amagwiritsa ntchito zolumikizira kutentha kuti apewe kupsa kwambiri kwa MOV. Izi zimapewa njira yayikulu yolephera ya SPD—kuthawa kwa kutentha.

Jeff akandifunsa malangizo kwa ogulitsa, nthawi zonse ndimasankha makampani omwe amagwiritsa ntchito QC yokhwima komanso zinthu zomwe zimagulitsidwa mosavuta, chifukwa kukwera kwa magetsi sikulekerera kufooka kwa kuwongolera khalidwe.

Kusankha Choteteza Choyenera cha Ma Surge Panels a Circuit Breaker

Nthawi zambiri ndimamva ngati ndatopa kwambiri ndikasankha chotetezera ma surge pa panel yotanganidwa yomwe dera lililonse limawoneka lofunika kwambiri.

Choteteza ma surge cha panel yophwanya ma circuit chiyenera kufanana ndi voltage ya system, surge group, ndi malo oyika. Ma unit a SPD a Type 1, Type 2, ndi Type 3 amateteza mfundo zosiyanasiyana za system, kuonetsetsa kuti ma surge atetezedwa ndi ma surge komanso kuti mafakitale azigwira ntchito bwino.

Ndikamayesa ma SPD a gulu la makasitomala, nthawi zonse ndimatsatira njira yotetezera yokhala ndi magawo:

Ngati mukufuna kufananiza mozama, ndikufotokozeranso kusiyana pakati pa mayunitsi a SPD a Mtundu 1 ndi Mtundu 2 mu kalozera wosankha watsatanetsatane wa SPD.

Pa mafakitale akuluakulu opanga zinthu, ndikupangira mtundu woyamba kapena wachiwiri wa SPD. Izi zimapereka chitetezo chodziwikiratu popanda kukayikira.

Ma breaker panel m'mafakitale nthawi zambiri amakumana ndi ma switching surges ochokera ku ma motors, ma compressor, makina ochapira, ndi ma HVAC systems. Ma intra-up awa amkati amapezeka mobwerezabwereza kuposa mphezi, kotero panel SPD yokhala ndi mphamvu yopirira mphamvu yopitilira ndi yofunika.

Ndaona kuti malo ogwirira ntchito ku Germany ndi France amayang'ana kwambiri malamulo ogwirizanitsa zinthu monga IEC 61643-11. Kutsatira malamulowa kumatsimikizira kuti ma SPD akumtunda ndi akumunsi sakukangana.

Oyang'anira kugula zinthu akandifunsa upangiri, nthawi zonse ndimafotokoza izi:

1. Sankhani ma SPD okhala ndi zizindikiro zomveka bwino.

2. Gwiritsani ntchito mabasi a mkuwa ngati n'kotheka.

3. Onetsetsani kuti nthaka ili yolimba mokwanira kuti itulutse madzi mwachangu.

4. Pewani ma SPD opanda chitetezo choletsa kutentha.

Kukhazikitsa kwabwino kwa SPD breaker panel kumatha kusunga mzere wonse wopanga kwa zaka zambiri.

Chifukwa Chake Chipangizo Choteteza Mphezi N'chofunika Kwambiri Pachitetezo Cha Mafakitale

Ndaona zomwe mphezi ingachite pazida zakunja, kotero sindimalephera kuteteza mphezi popanga makina amagetsi.

Chipangizo choteteza mphezi chimateteza makina a mafakitale ku mphezi zachindunji ndi zosalunjika mwa kupititsa patsogolo mphamvu zamagetsi zambiri pansi mosamala. Chimaletsa kupsa kwa zida, kusungunuka kwa zingwe, ndi zoopsa zamoto, makamaka m'mafakitale omwe ali ndi malo akuluakulu akunja.

Kuphulika kwa mphezi nthawi zambiri kumafika pa ma volts zikwi makumi ambiri. Popanda mphamvu yamphamvu choletsa kukwera kwa mpweya, makina amagetsi amayamwa zambiri zomwe zawonongeka.

Nazi madera a mafakitale komwe nthawi zonse ndimayika zida zotetezera mphezi:
