Izixhobo zokukhusela izixhobo zokusetyenziswa kwemizi-mveliso

Izicelo zeshishini zibandakanya iintlobo ezahlukeneyo zezixhobo ezifuna ukukhuselwa kwiziphumo zokunyuka. Ziyabiza kumnini wenkampani: ixabiso linokuba likhulu kwaye ukungaphumeleli, okanye ukutshintshwa, kwezi zixhobo, kuya kubangela ilahleko enkulu yemali, mhlawumbi kubeka ubukho benkampani emngciphekweni. Imiba ephambili, ngokwembono yeemanyano zabasebenzi, ngabaqeshwa: basebenzisa izixhobo zombane kwaye, kwimeko yotyando, ubomi babo bunokuba semngciphekweni. Iinyani ezichazwe apha ngasentla, kunye nezinye izizathu, zibonisa izizathu ezivakalayo zokuba umntu afune ukukhuselwa kwi-surges. Lo msebenzi usebenzisa ukhuselo lwangaphakathi nolwangaphandle kumbane, ezinje ngeetheminali zomoya, isiseko, ibarbar ekhuselayo, abacinezeli bokunyuka, konke kubhekiswa ngokudibeneyo njengezixhobo zokukhusela, SPD. Kukho inani leenkampani ezivelisa ubuninzi bezixhobo, kodwa ayizizo zonke ezifanelekileyo kwizicelo zeshishini.

Intliziyo yako konke, njengoko kunjalo njalo, ilele kumyalelo okanye kwimfuno yomthetho. Kule meko ikhethekileyo, kumgangatho oqhelekileyo we-EN 62305 woKhuselo loMbane, Icandelo I ukuya kwi-4. Isicatshulwa sikwachaza iintlobo ezahlukeneyo zelahleko, umngcipheko, iinkqubo zokukhusela umbane kunye nenqanaba lokhuseleko lombane. Kukho amanqanaba amane okhuseleko lombane (I ukuya ku-IV) acacisa iiparameter zombane; amanqanaba okhuseleko ngumsebenzi wenqanaba lomngcipheko. Kuninzi lwezicelo zorhwebo, isakhiwo sihlelwa njengeNqanaba I okanye II. Oku kuyahambelana nexabiso lokuphakama kombane ngoku_imp (impembelelo yangoku eneeparameter eziyi-10/350 beings) eziphakamileyo njenge-200 kA. Uqikelelo olufanelekileyo lubonisa ukuba i-50% ye-I iyonke_imp Okwangoku kubanjwa ziitheminali zomoya kwaye kusiwa kwinkqubo yomhlaba. I-50% eseleyo isasazwa ngokulinganayo phakathi kwegalelo (okt phakathi konxibelelwano lwangaphandle olungena kwisakhiwo), ngesiqhelo kwi-IT kunye neentambo zonxibelelwano, imibhobho yesinyithi kunye neentambo zombane ze-LV.

Kwiimeko ezimbi kakhulu, i-SPD kufuneka ibambe kangange-100 kA. Xa zisasazwa zangumtya ngamnye, amaxabiso akhoyo ngoku angama-25 kA ngentambo nganye (kusetyenziswa inkqubo ye-TN-C). Kungenxa yoko le nto sicebisa ukuba abasasazi abaziintloko bezixhobo zeyunithi ye-LV (kwizakhiwo ezifanelekileyo njengeLPL I inqanaba lokhuseleko) zifakelwe I-FLP50GR isithuba esitywiniweyo sentlanzi ngokugcwaliswa kwerhasi. Ukuba luhlobo lwe-1 lwe-SPD, izixhobo ziqinisekisa ukulinganiswa kokubakho kunye nokulahlwa kombane wangoku kunye nokutshintsha kombane okwenziwa kwimigca yokuhambisa umbane engena kwisakhiwo.

Iyakwazi ukundibamba_imp imijelo enkulu kangange-50 kA. Icandelo lezinto ezakhiweyo kwizakhiwo kufuneka zifakelwe I-FLP25GR, indibaniselwano yohlobo lwe-SPD 1 kunye no-2, ebonisa ii-varistors ezimbini zokhuseleko oluphezulu kunye nokubonelela nge-25 kA ye-pulse yangoku. Ukufakwa kwesekondari kunye neekhabhathi zolawulo kufuneka zixhotyiswe ngohlobo lwe-SPD 2. Umzekelo welo klasi kuluhlu lwemveliso yethu ngu I-SLP40, enikezelwa njengeyunithi epheleleyo, etywiniweyo okanye iimodyuli ezinokubuyiselwa.

Ukuba isixhobo esikhuselweyo simi ngaphakathi kwe-5 m ukusuka kwisikhululo sesibini okanye kwikhabhathi yolawulo, inkqubo kufuneka ixhotyiswe ngakumbi ngeyunithi ye-SPD yohlobo lwe-3, umzekelo, i-TLP10. Sisicoci esinefrikhwensi ephezulu esine-min. I-30 dB kwi-frequency band 0.15 - 30 MHz ekwanazo nezixhobo zokukhusela -i-varistors eziveliselwe imilinganiselo yokulinganisa ukusuka kwi-16 ukuya kwi-400 A. Kwimeko apho, isithintelo sesahlulo sokucinezelwa kwe-LC63 kufuneka sifakwe phakathi kwe-SPD Type 2 kunye 3 ukubonelela ngolungelelwaniso oluchanekileyo yababanjiweyo. Iintambo ezikhuselekileyo kufuneka zibonelelwe phakathi kwesitishi kunye nezixhobo ezikhuselweyo ukuze zisebenze ngokufanelekileyo.

I-LSP ikwabonelela ngokhuseleko kwiimeko apho uphahla lwesakhiwo luthwala iiphaneli ze-photovoltaic. Ingcebiso yethu yile I-SLP40-PV uthotho olunyukayo phambi kwe-inverter kunye nangaphakathi kufakelwe ii-disconnectors ezisetyenzisiweyo kwimeko yokungaphumeleli (ubushushu) be-varistors kunye nokuma koomatshini, okufakwa phakathi kwee-electrode ezingacinywanga ukulungiselela iimeko ezifanelekileyo zokubulala i-arc ye-DC. Ukukhuselwa kokunyuka kokutshintsha ngoku kuyimfuneko, olona khetho lulungileyo Uluhlu lweFLP7-PV.

Sicebisa ukuba ababanjwa balolu hlobo bafakwe kumagumbi afana neeholo zeseva, amagumbi okulawula kunye neeofisi. I-Tele-Defender-RJ11-TELE yokukhusela izixhobo zonxibelelwano, iNet-Defender-RJ45-E100 yokukhusela ukuhanjiswa kwedatha kunye neempawu zolwazi, I-COAX-BNC-FM ukukhusela izixhobo ezisebenzisa inkqubo ehambisa umqondiso wevidiyo, Umkhuseli weNet-ND-CAT-6AEA zenzelwe uthungelwano lweekhompyuter ngaphambi kokungena kwikhadi lothungelwano kwaye ziyinjongo eyenzelwe ukukhusela kunye nokuhanjiswa kwedatha kwinethiwekhi yesi-5, kwaye RJ45S-E100-24U yofakelo kubasasazi be-intshi ezili-19 kwiseva yokukhusela ukuhanjiswa kwedatha kuthungelwano lweekhompyuter: isixhobo sinika iziseko zeRJ45 kunye nezihlanganisi zeLSA-PLUS. Ukukhuselwa kwedatha kunye neendlela zonxibelelwano kunye nezixhobo ze-I & C kunye nolawulo lweendlela zemveliso, oomatshini kunye nezixhobo ezibalulekileyo, sicebisa ukuba kusetyenziswe Uthotho lwe-FLD2 ezihambisa ukukhuselwa ngombane obanjiweyo kunye ne-diode-voltage-suppress diode. Banikezelwa kuyilo olwahlukeneyo ngenani elinokukhethwa lezibini kunye namandla alinganisiweyo ombane kuluhlu olunikiweyo. Ukunxibelelana nonxibelelwano lwe-RS 485 ye-serial, sinika ukhuseleko lwale migca sisebenzisa uthotho lwe-FLD2 olukhusela izixhobo ezixhunyiwe ngokuchaseneyo nokunyuka okude. Ukukhuselwa kweekhamera kunye nevidiyo yokuhlanganiswa kweempawu, ngakumbi kwiinkqubo zokhuseleko zombane kunye neenkqubo zokukhusela umlilo kwi-EPS isebenzisa i-FLPD2 enezinto ezingezizo ezomda kwimisinga ye-Imax ukuya kuthi ga kwi-6.5 kA. Ukukhuselwa kwezixhobo eziqhagamshelwe kwinkqubo ye-eriyali ngentambo ye-coaxial kufuneka ifakwe kwisikhuseli sokunyuka I-LSP ibonelela ngoluhlu olubanzi lwabakhuseli be-coaxial kwiindidi ezahlukeneyo zonxibelelwano kunye neeklasi ezithile zendlela yokusebenza enokusetyenziswa kwiindidi ezininzi zezicelo. Le SPD iqulethe umbane okhethekileyo okhupha umbane okhoyo ngoku nge-Imax (8/20 µs) = 10 kA ukubonelela ngokhuseleko oluthembekileyo lwenkqubo yokwamkelwa kunye neenkqubo zosasazo ngokuchasene nefuthe lombane kufutshane. Banikezela ukucutha okuphezulu kokuphinda kungabikho ngaphantsi kwe-20 dB.

Umxholo wokukhuselwa kwi-surges ayisiyonto ilula; uyilo olululo luxhomekeke kwinani lezinto ezinegalelo. Siyakumema ukuba unxibelelane nabameli bethu abathembekileyo bokuthengisa abaya konwaba ukukucebisa ekukhetheni uhlobo olufanelekileyo lokukhuselwa kokukhusela impahla yakho kunye nokunciphisa ilahleko nokonakaliswa kwepropathi yakho.

Izidingo zokusetyenziswa kwezixhobo eziKhuselayo zoKhuselo (ii-SPDs) kwiiPaneli zoLawulo lwezoShishino

Izixhobo zokukhusela (ii-SPDs) zihlala zisetyenziswa kwiiphaneli zolawulo lweshishini. Itheyibhile engezantsi kukuchazwa kweentlobo ze-SPD kunye nendlela ezinokusetyenziswa ngayo kwiiphaneli apho kungekho nkcazo yeNkqubo ifunwayo. Izidingo zeVoltage kunye neNdawo yokuThunyelwa kweNgcaciso yeNqanaba (NDC) ze-SPD zibonisiwe kule theyibhile ingezantsi. Ii-SPDs ezisetyenziswa ngaphandle kwezikhokelo zale tafile zifuna inkcazo yenkqubo. Kuxhomekeke kuvavanyo lwe-SPD, ezi zikhokelo zinokugqitha ukuba kuvavanywa ubunjineli.

Itheyibhile isebenza kwi-SPDs enye, exhaphake kakhulu. Apho kusetyenziswa i "Two-Port" SPD, iyakuba luhlobo oluvumelekileyo kule theyibhile ingentla, ngokusekwe kusetyenziso lwephaneli, kwaye isetyenziswe ngaphakathi kwamanqaku ayo aphawuliweyo, kubandakanya ne-Short Circuit Current Rating (SCCR). Xa izibuko ezimbini zohlobo lwe-3 SPDs zingaphawulwanga nge-SCCR, kuthathwa ngokuba yi-1000A. Ukuba isixhobo esinezibuko ezibini samkelwe ngeNqaku 4 kwiPhepha loLwazi loLuhlu (esibonisa ukuba ukhuseleko lwangaphandle olungaphezulu luyafuneka), le SPD kufuneka ibe yinkqubo echaziweyo.

• R / C ichaza into eyaziwayo

1, ibandakanya iipaneli ezibhalwe "Zilungele ukusetyenziswa njengezixhobo zeNkonzo"

2, Ukulinganiswa kwamandla ombane we-SPD kuya kuba ubuncinci kwinqanaba lesekethe (LL) yombane kuzo zonke iindlela (okt i-LN, LL, LG). Umzekelo, iiphaneli ezikalwe nge-277 / 480V ziya kusebenzisa i-SPD ekalwe nge-480V kuzo zonke iindlela; Iiphaneli ezikalwe nge-120 okanye i-120/240 ziya kusebenzisa i-SPD elinganiswe nge-240V kuzo zonke iindlela.

Isigama seSPD:

Izibuko elinye-i-SPD ingaphaya komgca.

Izibuko ezimbini-i-SPD ingaphaya komgca, kunye neesekethe ezongezelelweyo kuthotho kunye nomthwalo. Ukuhamba ngoku kwesi sixhobo akuyi kudlula kumgangatho wangoku ophawuliweyo.

Amanqaku-Ukucaciswa kweemfuno:

• Apho ireyithi yevolthi ichaziweyo, amaxabiso eMCOV (aMandla oSebenzayo aQhelekileyo oSebenzayo) amaxabiso anokuba njalo
• Ukuchithwa kwegama ngokuKhangekileyo (i-NDC): Ngamana unokubhekiswa njenge-IN. Ukulinganiswa okuqhelekileyo zi-3kA, 5kA, 10kA, okanye 20kA.Iinkcazo-ukusuka kwi-UL1449 (iyafundisa)

Uhlobo lokalisho (olusebenza kwizatifikethi ngaphambi kuka-Epreli 2010):

Uhlobo lwe-1 -Ii-SPD ezixhume ngokusisigxina ezijolise ekufakweni phakathi kwesibini sombane osiguqulayo kunye necala lomgca lezixhobo zenkonzo ezijikelezayo, kunye necala lomthwalo, kubandakanya i-watt-yure yemitha evaliweyo kunye nokujongwa ukuba kufakwe ngaphandle kokugqitha okungaphandle isixhobo sokhuselo.

Ezi zixhobo zidwelisiwe.

Uhlobo lwe-2 -Ii-SPD ezixhume ngokusisigxina ezijolise ekufakweni kwicala lomthwalo wesixhobo seenkonzo ezingaphaya; kubandakanya ii-SPD ezikwiqela lesebe.

Ezi zixhobo zidwelisiwe.

Uhlobo lwe-3-Indawo yokusebenzisa ii-SPDs, efakwe kubuncinci beekhondomu ubude beemitha ezili-10 (iinyawo ezingama-30) ukusuka kwipaneli yenkonzo yombane ukuya kwinqanaba lokusetyenziswa, umzekelo, intambo eqhagamshelwe, i-plug-in ngqo, uhlobo lwesamkeli kunye nee-SPD ezifakwe izixhobo zokusebenzisa ziyakhuselwa. Jonga ukumakisha kuma-64.2. Umgama (i-10 yeemitha) ukhethekileyo kubaqhubi ababonelelwe okanye abasetyenziselwa ukufakela ii-SPD.

Ezi zixhobo zidwelisiwe.

Chwetheza ii-SPDs zeCandelo le-4, kubandakanya izinto ezingacacanga kunye neendibano zecandelo.

Ezi zixhobo zibonwa njenge- “Type 4 for use in xxx applications” apho i-xxx isenokuba ngu-1, 2, 3, okanye “enye”. Ukulinganiswa kohlobo (olusebenza kwizatifikethi emva ko-Epreli 2010):

Uhlobo lwe-1 -Ii-SPD ezixhume ngokusisigxina ezijolise ekufakweni phakathi kwesibini sombane osiguqulayo kunye necala lomgca lezixhobo zenkonzo ezijikelezayo, kunye necala lomthwalo, kubandakanya i-watt-yure yemitha evaliweyo kunye nokujongwa ukuba kufakwe ngaphandle kokugqitha okungaphandle isixhobo sokhuselo.

Ezi zixhobo zidwelisiwe.

Uhlobo lwe-2 -Ii-SPD ezixhume ngokusisigxina ezijolise ekufakweni kwicala lomthwalo wesixhobo seenkonzo ezingaphaya; kubandakanya ii-SPD ezikwiqela lesebe.

Ezi zixhobo zidwelisiwe.

Uhlobo lwe-3-Indawo yokusebenzisa ii-SPDs, efakwe kubuncinci beekhondomu ubude beemitha ezili-10 (iinyawo ezingama-30) ukusuka kwipaneli yenkonzo yombane ukuya kwinqanaba lokusetyenziswa, umzekelo, intambo eqhagamshelwe, i-plug-in ngqo, uhlobo lwesamkeli kunye nee-SPD ezifakwe izixhobo zokusebenzisa ziyakhuselwa.

Ezi zixhobo zidwelisiwe.

Chwetheza 1, 2, 3 Iindibano zeCandelo -Ibandakanya indibano yecandelo 4 kunye nokhuseleko lwangaphakathi okanye lwangaphandle olufutshane.

Ezi ziindibano ezifanayo ne-UL508's "Open Type Devices." Banokuba ngumgaqo kaloliwe we-DIN ofakelwe ufakelo lwepaneli. Uhlobo lwe-1 kunye ne-2 yeendibano zecandelo ziye zavavanywa ngokufutshane kwesekethe.

Uhlobo lwe-4 ye-Assemblies yecandelo-Indibano yecandelo elinento enye okanye ezingaphezulu zohlobo lwe-5 kunye nokucinywa (okuhlanganisiweyo okanye kwangaphandle) okanye iindlela zokuthobela iimvavanyo ezikhoyo ngoku kwicandelo le-UL1449 44.4 (ushicilelo lwe-4). Ezi zixhobo ziyaqatshelwa, ngokungafaniyo zinendlela ethile yokukhusela i-thermal. Banokuthi okanye bangakhange bavavanywe ngokufutshane kwesekethe.

Uhlobo lwe-5 -Izinto ezinyanzelekileyo zokucinezela abaxhasi, ezinje ngee-MOV ezinokuxhonywa kwi-PWB, edityaniswe kukukhokela kwayo okanye ibonelelwe ngaphakathi kwendawo ebiyelweyo eneendlela zokunyusa kunye nokupheliswa kweentambo.

Ezi zixhobo ziyabonwa, zihlala zinqamlezileyo ngaphandle kokukhuselwa kobushushu.
