Thetha malunga nemiba ethile yezixhobo zokhuselo lotyando (SPDs)
1. Ezinye iingxaki ze "OBO style structure"
Izixhobo zokukhusela zaseTshayina (SPDs) imveliso yobuninzi esekwe kwiDehn, OBO, kunye noyilo lwesakhiwo seCitel. Nangona kunjalo, ngophuhliso lwetheknoloji kunye nokusebenza, ukuqokelela kwemveliso evuthiweyo kutshintsha rhoqo, njengeDehn, iPhoenix, iRaycap, i-OBO, i-Citel, i-Hakel, i-Saltek yokukhusela i-surge, isoloko iqhubeka iza kunye neendlela ezintsha kunye neemodeli. Olu tshintsho alugcini nje ukwenza utshintsho olufashiniweyo, ulwahlulo, kodwa kuninzi lwesakhiwo kunye nomsebenzi wokuphucula. Kodwa jonga uninzi lweefektri zase China SPDs, zisasebenzisa uyilo lwakudala lwesakhiwo esinjengesitayile se-OBO:
1.1 Isimbo soqhagamshelwano lokhuseleko lwesekethe emfutshane
Ngaphambi kokwenza uvavanyo lwangoku lokukhupha okukhulu
Emva kovavanyo, unamathele kunye nokukhutshwa okukhulu kwangoku.
Amagqabantshintshi: Ukuhlangabezana nokuqina okuhambelanayo kombane okhoyo ngoku, ukunciphisa indawo enqamlezayo yabafowunelwa kunokuphucula amandla okhuseleko olufutshane lwesekethe, kodwa kufuneka baqonde ukuba ukukhupha i-fusing yangoku kunye ne-short-circuit fusing ngumba ophikisanayo, kufuneka kuthathwe. imifuniselo emininzi, ayinciphisi ngokumfamekileyo indawo enqamlezileyo yabafowunelwa.
1.2 Uyilo lomgca
Kukho isiphene soyilo kwisakhiwo se-OBO, indlela yokuhamba, kunye ne-MOV kwigumbi elifanayo, lithetha uqhagamshelwano oluphezulu lwe-voltage kunye ne-low-voltage contacts kwigumbi elinye.
(i-copper braid snap; ukunyibilika kwe-solder)
Ngokomgaqo we-electromagnetism, ulwalathiso olufanayo lwangoku lutsala omnye nomnye, njengoko kubonisiwe ngasentla, xa ubhedu uluka ixesha elide, iya kutsala phakathi komqhubi wesalathiso esifanayo ngoku kunye nomqhubi wesalathiso esichaseneyo, kuba ubhedu braid bunitha kwaye banakho Ukolula, kwenza isiphumo esingentla
1.3 I-Welding ayinamandla phakathi kwe-copper braid kunye ne-copper strip
Ubume besitayela se-OBO, kukho indawo eninzi yomsebenzi kule ndawo, kulula ukutsala umgca emva kwempembelelo yangoku yokukhupha, i-welding ilula ukuqhawula.
1.4 Ibha yeplastiki eluhlaza kulula ukuyonakalisa
Inqaku elibalulekileyo kwi-bar yeplastiki eluhlaza kukuhla ngokulula, ubomvu bubonisa kwifestile ebonakalayo, yenza i-misoperation (isenzo esingalunganga). Ibangela ngesizathu esifanayo nesentla kwenqaku lesi-3.
1.5 Umgama wokukhubeka ukhutshiwe mxinwa kakhulu
I-Solder tin kancinane ngakumbi, ukhuseleko lobushushu obungaphezulu aluyi kukwazi ukukhulula ngokupheleleyo. Umgama wokukhutshwa kwe-tripping ungaphantsi kwe-5mm kule sakhiwo sesitayela se-OBO, abavelisi be-SPD kufuneka banikele ingqalelo kuyo.
Ukongeza, phinda-phinda isakhiwo sokukhulula se-DEHN esiphelelwe lixesha
I-MOV kunye nenkqubo yokukhutshwa kokukhutshwa kwigumbi elahlukileyo, umgama wokukhutshwa kokukhutshwa u-approx. I-10mm, ibha yeplastiki ayichatshazelwa ngamandla e-electrodynamic.

Umba ongahoywayo wesixhobo sokhuselo se-IP20
Ukutyhubela iminyaka, uvavanyo lwe-SPDs lukhathalela i-voltage eshiyekileyo, i-excharge current, i-transient overvoltage (TOV), ukuzinza kwe-thermal, ii-pulses ezininzi, kodwa ayihoywa olona vavanyo lusisiseko lwezixhobo zombane ezisezantsi zokunxibelelana ngokuthe ngqo.
Kwisiqingatha sonyaka, i-SPD yokuvavanya i-laboratory ifumana i-SPD eninzi engafanelekanga kwiklasi ye-IP20, le ngxaki iyenzeka kakhulu kwisiseko sesitayela se-OBO endala, ukubiza iifektri zaseTshayina ze-SPD azisayivelisi, kukho iingxaki ezininzi kunye nesiphene sesakhiwo kwisitayile esidala se-OBO ye-SPD. .
Ziziphi iindlela ze-IP20?
Inani '2' lithetha ukukhusela i-12mm eqinileyo (efana nobukhulu boMnwe) ukungena, usebenzisa iminwe yokulinganisa ukuqinisekiswa.
Inani '0' lithetha inqanaba lokungangeni kwamanzi.
Sukucinga ukuba akukho ngxaki kwimveliso yakho, uhlolo olubonakalayo lunokuba sisigwebo esiqatha.
Ukufota ngasekhohlo: ufanelekile, umphezulu we-screw subsidence malunga ne-1.5 mm
Ukufota okufanelekileyo: akufanelekile
Xa uqina kwaye ukhulule, indawo yobuso be-screw kufuneka ingatshintshi.
Ubume bokuqina
Emva kokujonga, phantsi kwemeko yezindlu ze-SPD ngaphandle kokwahluka, fumana izikrufu ze-IP20 ezingafanelanga nokuba azifaneleki xa zifakwa kwizindlu eziqeqeshiweyo.
Njengokufota apha ngasentla, ukufota ekhohlo: kungachukunyiswanga, ukufota okufanelekileyo, ukufota ngasekunene: ukuchukunyiswa, isikrufu esingafanelekanga
Emva kokulinganisa, ukucaciswa kwe-screw kuhambelana, Ingxaki iyenzeka kwisakhiwo seendawo zetsimbi.
Umphezulu we-screw awulingani xa ufakwe kwisakhiwo seengxenye zetsimbi.
kwaye kufunyenwe ukuba kukho iiyantlukwano kwimilo yesakhiwo.
Ukuba ufuna ukuhlangabezana neemfuno zeklasi ye-IP20, ubungakanani besakhiwo sesinyithi kufuneka bungaphantsi kwe-2 cm.
okanye usebenzise i-terminal cover, ngaphandle koviwo.
