Ndiyidinga nini i-surge protector ukuze ndikhuseleke kumbane?

Mnaintshayelelo

Njengoko izixhobo ze-elektroniki zingena kuzo zonke iikona zobomi banamhlanje, ingxaki yamandla engabonakaliyo iyavela. Ukunyuka kwamandla ombane - oku kwenzeka ngequbuliso kwamandla ombane agqithisileyo - kubangela ukuba izigidi zezixhobo ze-elektroniki kwihlabathi liphela "zithathe umhlala-phantsi" ngaphambi kwexesha minyaka le. Njengesixhobo "esikhusela iimbumbulu" kwinkqubo yamandla, ukubaluleka kwezixhobo zokukhusela amandla ombane (ii-SPD) kuye kwathathelwa ingqalelo kakhulu.

Ⅰ. Yintoni isikhuseli sokunyuka?

Isixhobo sokukhusela ukuvuza (i-SPD) sisixhobo esisetyenziselwa ukunciphisa i-transient overvoltage kunye ne-discharge surge current, esenzelwe ukukhusela izixhobo zombane neze-elektroniki kwi-voltage surges ebangelwa ngumbane okanye ukusebenza kwegridi.

1.1 Imisebenzi Engundoqo

• Ukufunxa okanye ukujika i-overvoltage: Xa kwenzeka i-voltage ephezulu engaqhelekanga kwigridi yamandla okanye kwiintambo, i-SPD ikhawuleza iqhube kwaye idlulisele amandla angaphezulu emhlabeni.

• Ukukhusela izixhobo ezibuthathaka: Ukuthintela iikhompyutha, izixhobo zonxibelelwano, iinkqubo zolawulo lwemizi-mveliso, njl.njl. ukuba zonakaliswe ngenxa yokuguquguquka kwamandla ombane.

• Ukuphucula ukuthembeka kwenkqubo: Ukunciphisa ixesha lokungasebenzi kunye neendleko zokulungisa ezibangelwa kukunyuka okukhulu.

1.2 Izikhuseli zokunyuka ikani zihlelwe ngokweemeko zazo zokusetyenziswa kunye namanqanaba okhuseleko ngolu hlobo:

- Uhlobo 1 (Ukhuseleko Oluphambili): Lusetyenziswa kwisiphelo sombane wesakhiwo ukuzikhusela ekubethweni ngumbane ngokuthe ngqo.

- Uhlobo 2 (Ukhuseleko Lwesibini): Isetyenziswa kwinkqubo yokusasazwa kwamandla ukukhusela umbane obangelwayo kunye nombane ogqithisileyo osebenzayo.

- Uhlobo 3 (Ukhuseleko Oluphezulu): Isetyenziswa kwizixhobo zesiphelo, ezifana nokhuseleko lwesokhethi.

Ⅱ. Nini Ngaba kufuneka usebenzise i-surge protector?

2.1 Umbane-iindawo ezisengozini

Umbane yenye yezona zinto ziphambili ezibangela ukunyuka kwamanzi. Izikhuseli zokukhuphuka kwamanzi kufuneka zifakelwe kwezi meko zilandelayo:

- Izakhiwo eziphakamileyo: Amathuba okuba kubekho umbane othe ngqo aphezulu, ngoko ke ii-SPD zohlobo lwe-1 kufuneka zifakwe kwinkqubo yokusasazwa kwamandla.

- Izitishi zonxibelelwano: Ukubetha kombane kunokubangela ukuphazamiseka kwesignali, ngoko ke ii-SPD kufuneka zongezwe kwimigca yesignali.

- Izitishi zamandla elanga: Izixhobo ze-photovoltaic zisengozini yokubethwa ngumbane, ngoko ke ii-SPD kufuneka zifakwe kwii-inverters nakwiibhokisi ze-combiner.

Ityala: Kwisixeko esiselunxwemeni, inqaba yonxibelelwano yonakele ngenxa yombane kuba akukho SPD ifakiweyo. Ilahleko idlule kwi-1 yezigidi zeeyuan.

2.2 Imizi-mveliso kunye nemeko yokuvelisa

Izixhobo zoshishino zinobuthathaka kakhulu kutshintsho lwe-voltage. Ezi meko zilandelayo zifuna ukusetyenziswa kwe-SPD:

- Imigca yemveliso ezenzekelayo: Izixhobo ezichanekileyo ezifana nee-PLC kunye nee-frequency converters zisengozini yokuhlaselwa ngamandla.

- Amaziko edatha: Iiseva kunye nezixhobo zokugcina zifuna i-SPD ukuthintela ukulahleka kwedatha.

- Izixhobo zonyango: Izixhobo zonyango ezikumgangatho ophezulu ezifana noomatshini be-MRI kunye ne-CT zinemfuno ephezulu kakhulu yomgangatho wamandla.

Inkxaso yedatha: Ngokwezibalo, malunga ne-35% yeemeko zomonakalo wezixhobo zoshishino zinxulumene nokunyuka kwamandla ombane.

2.3 Indlu kwaye Umbane woRhwebo

- Inkqubo yasekhaya ekrelekrele: IiTV ezikrelekrele, iikhamera zokhuseleko, njl.njl. zifuna ukhuseleko lwe-SPD.

- Izakhiwo zeeofisi zorhwebo: Izixhobo ezinkulu ezifana neelifti kunye nee-air conditioner zifuna amanyathelo okukhusela ukuxinana kwamanzi.

- Umbane ofumaneka kwiindawo ezikude: Iindawo ezineegridi zamandla ezingazinzanga zisengozini yokuguquguquka kwamandla ombane.

Ingcebiso: Kubasebenzisi basekhaya, i-Type 2 SPD ingafakwa kwibhokisi yokusasaza, kwaye i-Type 3 SPD ingongezwa phambi kwezixhobo ezibalulekileyo (ezifana neekhompyutha).

2.4 Entsha amandla kunye neziseko zophuhliso zamandla

- Ifama yomoya: Inkqubo yokulawula i-wind turbine ifuna ukhuseleko lwe-SPD.

- Isikhululo sokutshaja izithuthi zombane: Ukutshaja ngamandla aphezulu kunokubangela i-overvoltage yokusebenza ngokulula.

- Isitishi esingaphantsi: Ii-SPD kufuneka zifakwe kwisiphelo somgca ongenayo ukuthintela ukungena kombane.

2.5 Ekhethekileyo imboni izicelo

- Ishishini le-Petrochemical: Iindawo ezingenakudutyulwa zifuna ukusetyenziswa kwee-SPD ezingenakudutyulwa.

- Oololiwe kunye nezothutho: Iinkqubo zemiqondiso kufuneka zixhotyiswe ngee-SPD ezithembekileyo kakhulu.

III. Njani ukukhetha isikhuseli sokushushuluza esifanelekileyo?

Misela inqanaba lokhuseleko (Uhlobo 1/2/3).

Cinga ngomlinganiselo ophezulu wokukhupha umbane (i-Imax) kunye nenqanaba lokukhusela i-voltage (Phezulu).

Khetha iimveliso ezihambelana nemigangatho yamazwe ngamazwe (njenge-IEC 61643, UL 1449).

Ukuhlolwa rhoqo kunye nokutshintshwa: Ii-SPD ziya kwaluphala ngenxa yokunyuka okuphindaphindiweyo, kwaye kufuneka zihlolwe rhoqo.

IV. Ikamva Iindlela Ezithandwayo kunye noBuchule boBugcisa

- I-SPD ekrelekrele: Ingajonga iziganeko zokusasazeka kwesantya ngexesha langempela kwaye ivuse ii-alamu nge-Intanethi yezinto.

- Uyilo lweModular: Lunceda ukutshintshwa nokugcinwa kwesakhiwo.

- Ukunyamezela amandla aphezulu: Iyaziqhelanisa neemfuno zegridi zamandla amatsha.

Ⅴ. Isiphelo

Ngenxa yokuvela rhoqo kwemozulu embi kakhulu kunye nokusetyenziswa ngokubanzi kwezixhobo ezichanekileyo, imakethi yezixhobo zokukhusela ukuvuza (i-SPD) ikhula ngokukhawuleza. Idatha yeshishini ibonisa ukuba ezi zixhobo, ezaziwa ngokuba "zizithintelo zokuvuza ngombane", zandise iimeko zazo zokusetyenziswa ukusuka ekusasazweni kwamandla okwakha ngokwesiko ukuya kwiindawo ezikhulayo ezifana nezikhululo zesiseko ze-5G, izikhululo zamandla ze-photovoltaic, kunye namaziko edatha.

"Umonakalo wezixhobo udla ngokuqala ngokunyuka kwamandla ombane angabonakaliyo," ingcali yokhuseleko lombane yelebhu yesizwe itshilo. Uphando lubonise ukuba ukufaka ii-SPD ngokufanelekileyo kunokunciphisa izinga lokungaphumeleli kwezixhobo ze-elektroniki ezibangelwa kukubetha kombane ngaphezulu kwama-70%. Nangona kunjalo, kubalulekile ukuqaphela ukuba ukusebenza kweemveliso kwimarike kwahluka kakhulu - ukusuka kwiimodeli ezisisiseko ukuya kwezikrelekrele ezihlengahlengiswayo, kunye nomahluko wenqanaba lokhuseleko ukuya kuthi ga kwi-10.

Ukungaqondani ekukhetheni imveliso kuxhaphake kakhulu. Abanye abasebenzisi balandela iimveliso ezixabiso liphantsi ngokungaboniyo kodwa bayayityeshela imilinganiselo ephambili efana nesantya sempendulo kunye nomthamo wokuphuma. Umngcipheko ofihlakeleyo ngakumbi ukwinyani yokuba ezinye izixhobo ezibhalwe "njengezinga lemizi-mveliso" zihlangabezana kuphela nemigangatho yoluntu. Iingcali zicebisa ukuba kusetyenziswe icebo "lokuhlela umngcipheko wokusingqongileyo": iindawo ezibalulekileyo ezifana nezibhedlele kunye namaziko emali kufuneka zixhotyiswe ngenkqubo yokukhusela enamanqanaba amathathu, ngelixa izindlu eziqhelekileyo zinokusebenzisa isisombululo esidibeneyo esingabizi kakhulu.

Ngenxa yokwanda ngokukhawuleza kwezixhobo ze-IoT, isizukulwana esitsha se-SPDs sidibanisa imisebenzi efana nokubeka esweni ubushushu kunye ne-alamu ekude. Umphathi wolondolozo wenkampani yegridi yamandla utyhile ukuba emva kokufaka inkqubo yokukhusela ekrelekrele, iindleko zonyaka zokugcinwa kwezikhululo zazo zinciphile ngama-230,000 yuan. Nangona kunjalo, ukuphuculwa kwetekhnoloji kuzisa nemingeni emitsha. Indlela yokulinganisela ukusebenza kokhuseleko kunye nokuhambelana kwenkqubo iye yaba yeyona nto iphambili kuphando nophuhliso lweli shishini.
