Mangani maJoules ekudzivirira Surge? Gwaro Rakazara Rekutenga
Ndakakangwa bhodhi reCNC remadhora zviuru zvitatu gore rapera nekuti ndakatenga strip ye200-Joule zvishoma; hwema hwacho huchiri kundimutsa.
Chidziviriro chakanaka che surge chinotangira pa600 Joules yegiya diki uye chinokwira kupfuura 2,000 Joules yemaseva kana michina yeCNC. Enzanisa nhamba nemutengo wechinhu chawaisa.
Pazasi apa ndinotsanangura nhamba chaidzo dzaunoda, kuti sei kuyera kukosha, uye kuti ikozvino ndinotsanangura sei mitsetse yefekitori yangu kuti ugone kukopa pepa uye usazomborasikirwa nebhodhi zvakare.
Sei Uchifanira Kufarira Nezve Kuyera Joule?
Ndakamboramba "Joules" ndichiti inyaya yekushambadza isina basa—kusvikira kukwira kamwe chete kwaita kuti ndibvise vhiki rese rekugadzira uye kwakandibhadharisa mari yekutakura zvinhu nendege.
Kana chibodzwa cheJoule chakaderera zvakanyanya, mutsetse unofa mushure mekurovera kamwe chete uye michina yako inoramba ichidya maspikes. Sarudza nhamba chaiyo uye mutsetse mumwe chete unotora kurohwa mushure mekurovera kwemakore.
Ndisati ndaraira chero mudziyo une zvidimbu, ndinomhanya nekukurumidza kuongorora njodzi: nyora mudziyo wega wega uri pabhenji, nyora mutengo wekutsiva, wobva wawedzera 20% yekuchengetedza. Tafura iri nyore inondiudza maJoules mashoma andinogona kugamuchira. Kana sampuro yefekitori ikapinda pasi penhamba iyoyo, ndinoramba lot—hapana email yechipiri, hapana kutaurirana. Ndakadzidza nenzira yakaoma kuti strip yakachipa ye $0.50 inogona kudzima odha ye $50,000.
Mashandiro anoita Joules muhupenyu chaihwo
Funga nezve Majoules anofarira tangi remafuta mumotokari yako. Tangi re500-Joule rinogona kunwisa simba re500 "spike" risati rapera metal-oxide varistors (MOVs). Tangi re2,000-Joule rinogara kwenguva yakareba ka4 pasi pemaspikes akafanana. Masvomhu acho akarongeka, saka ndinochengeta pepa rekunyepedzera rakanamirwa padhesiki rangu:
| Rudzi rweChishandiso | Saizi Yakajairika yeSpike | MaJoules Akachengeteka |
| Chaja yefoni | 50 J | 300 J |
| Laptop PSU | 150 J | 600 J |
| Bhodhi reCNC rine mativi matatu | 400 J | 1,800 J |
| Raki yeseva PSU | 600 J | 2,500 J |
Mutengo Wakavanzika we "Just Enough" Joules
Vatengi vanoda kubvisa mari shoma muBOM, asi mutsetse unofa mushure mekurova kamwe chete unomanikidza kuti ubve wachinja-chinja panguva yekugadzirisa inotevera. Nguva iyoyo yekushaikwa kwemagetsi inogona kudhura kupfuura bhajeti rese rekuchengetedza surge. Iye zvino ndinofungidzira kuti mutsetse wacho upfuure kaviri pane Joules dzakaverengerwa kuitira kuti urambe uripo kusvika nguva inotevera yekudzima yakarongwa.
Ndezvipi maJoules ari paSurge Protector?
Ndichiri kurangarira chiso chemutengesi wangu pandakamukumbira kuti andiratidze nhamba dzezvikamu zveMOV—aiziva kuti mutambo wacho wapera.
Majoules ndiwo simba rese rinogona kumedza MOV pack isati yapera. Verenga UL sticker, kwete font yakasimbiswa iri pamberi, nekuti mamwe mabrandi anowedzera nhamba dzeMOV nhatu kunyangwe nzira imwe chete iri kushanda.
Mukati mechidimbu chimwe nechimwe muchawana dhisiki rebhuruu rimwe chete kana anopfuura ane saizi yekota. Idzodzo MOVs. Dhayamita neukobvu hwadzo zvinopa chiyero chesimba, kwete imba yepurasitiki. Ndinoda dhisiki re14 mm remaJoules chiuru uye 20 mm remaJoules chiuru. Kana fekitari ikatumira madhisiki e10 mm, ndinobva ndaenda.

Nei Vamwe Vachireva Nhema?
Chinhu chisina kunaka ndechekubatanidza MOV nhatu dziri pakati pema "line-to-neutral", "line-to-ground", "neutral-to-ground", wobva wawedzera "ratings" dzavo. UL inongoverenga nzira diki chete, saka nhamba chaiyo chikamu chimwe muzvitatu chemusoro wenyaya. Ndinogara ndichikumbira mushumo webvunzo weUL 1449 ndotenderedza "single-point rating". Kana mutengesi akatadza, ndinodzima "quote".
Mangani maJoules anodiwa pazviitiko zvakasiyana?
Ndinochengeta kadhi rakaiswa laminated muchikwama changu chepasipoti rine zvirevo chaizvo zveJoule zvechigadzirwa chega chega chandinotenga; vamiririri vemitero vanofunga kuti ndiri munhu asinganzwisisike, asi mutsetse wangu haumbofi wakaderedzwa.

Makesi eEdge Vanhu Vanokanganwa
Madhiraivha emota anodzosera kumashure maspikes eEMF anogona kupetwa kaviri kupfuura voltage yemutsara. Ndinogara ndichipeta Joule rating kaviri kana mutoro wacho uchibatsira. Macharger emabhatiri ndeimwe nzira yekutambisa—anotaridzika seasina njodzi, asi switched-mode supply inogona kudzosera 800 J mumutsara kana relay yavhurwa. Ndakarasikirwa neoscilloscope yemadhora mazana mapfumbamwe nenzira iyoyo; ikozvino bhenji rega rega rekuyedza rinowana 1,500 J zvishoma.
Nei High Joule Rating Yakakosha Pamidziyo Yako Yemagetsi
Musi wakamira mutsetse wangu wekutora nekuisa, ndaiva nevashandisi gumi nevaviri vakamira vasina chekuita nemutengo wemadhora makumi masere paawa imwe neimwe—madhora mazana mapfumbamwe nemakumi matanhatu paawa nekuti mutsetse we400-Joule wakarega.
Mitsetse yeHigh Joule inoshanda sechipanji chakakura; inonwisa marobhoti anodzokororwa kuitira kuti michina yako irambe ichishanda uye vimbiso dzako dzewaranti hadzina.
Kurova kwega kwega kweMOV kunonetsa. Chishandiso che500-Joule chinofa mushure mekunge chimwe chezvishandiso zve400-Joule charova, asi chishandiso che2,000-Joule chinobvisa zvitambiso zvina zvakafanana. Izvi zvinoreva kuti unochinjana ma strips paPM inotevera, kwete panguva yekufona kwe emergency.

Masvomhu acho akaomarara: kuchengetedza $1.60 pakutanga kunogona kudhura mari yakawanda gare gare. CFO wangu akazorega kupopotedzana pandakamuratidza bepa iri.
Mufananidzo Wandinochengeta weKukundikana Kwenyika Chaiyo
Ndakabaya chidimbu che600-Joule pabhodhi rezviziviso padyo newachi yenguva. MOV yakavhurika sebhisikiti ndokupisa purasitiki. Padivi payo pane chidimbu che3,000-Joule chakarova mheni imwe chete asi chichiri kuyedzwa zvakanaka. Hapana chikonzero chekutaura; mufananidzo ndiwo unoita kudzidziswa.
Mangani maJoules ari Akanaka Anodzivirira Surge?
Ndinoudza mutengi wese mutsva mutongo mumwe chete: "Zvakanaka zvinotanga pa1,000 Joules uye zvinokwira kusvika mutengo waderera zvishoma pane nguva yekuzorora."
Chidziviriro chakanaka che surge chine maJoules chiuru, UL 1449 certification, uye voltage ye clamping iri pasi pe400 V. Chero chipi zvacho chiri pasi i power strip, kwete dziviriro.
Ndinoita checklist yekupedzisira ndisati ndasaina PO: UL file number, single-point Joule rating, 14 mm MOV minimum, uye 100 kA short-circuit test. Kana fekitori ikaongorora zvese zvina, strip yacho inowana logo yangu uye waranti yemakore mashanu.
