I. Cov ntsiab cai ntawm Dual tawg - effe pov thawj mechanism
1. Tawg {{-} Cov ntaub ntawv pov thawj cais tawm hauv ib puag ncig sab nraud los ntawm kev tawg sab nraud thiab tuaj yeem tiv thaiv kev tawg sab hauv tawg.
2. Kev muaj kev nyab xeeb Circuit Court: Qhov txwv tsis pub tshaj tawm cov hluav taws xob (xws li voltage thiab tam sim no) kom ntseeg tau tias lub zog hluav taws xob tsim tawm hauv qab lossis kev sib xyaw ua ke tsis tuaj yeem nres.
Ii. Daim Ntawv Thov Kev Noj Qab Haus Huv
1. Xaiv thiab kev teeb tsa tsim nyog: Xaiv cov raug tawg- Cov ntaub ntawv ua pov thawj (piv txwv li ntawm thaj chaw (piv txwv li 0, cheeb tsam 1).
Cov tawg -} ntawv pov thawj yuav tsum tsis txhob muaj kev tsis zoo ntau dua lossis sib npaug nrog cov neeg ua haujlwm tshwj xeeb lossis sib npaug nrog cov tshuaj tiv thaiv tshwj xeeb.
Kev saib xyuas hluav taws xob muaj kev nyab xeeb yuav tsum muaj kev tiv thaiv kev nyab xeeb thiab kev nyab xeeb cable kom paub tseeb tias kev ntseeg ncaj ncees.
2. Kev sib khi thiab sib khi: cov xaim hluav taws xob tau qhia los ntawm kev tawg- ein}} ntaub ntawv pov thawj yog siv los ua kom tsis txhob xoob lossis xau dej. Siab - voltage thiab tsawg {{{{{{{{Voltage wiring yuav tsum tau sib cais nyob rau hauv ib qho loj dua los yog sib npaug rau 80mm kom tiv thaiv kev cuam tshuam.
3. Kev tshuaj xyuas thiab tshuaj xyuas: tsis tu ncua sckion {{}} Cov ntaub ntawv pov thawj sib xyaw, thiab ntxuav plua plav thiab ntxuav plua plav thiab cov roj.
Kev siv PTFE daim kab xev lossis sealant ntawm tawg -} ntawv pov thawj yog txwv; Tsuas yog kev tiv thaiv - rust grease yog tso cai.
III. Kev Ua Tshwj Xeeb
1. Cov Txheej Txheem Tseem Ceeb: GB 3836.1 - 2021 (Qhov Kev Tshawb Fawb), GB 3836.4-2021 (intrinsically).
2. Kev teeb tsa yuav tsum tau ua: Qhov nkag yuav tsum tau ntim; Threaded kev sib txuas tau zoo ntau dua los yog sib npaug rau 8 hli; Wrapping nrog tsis- tawg - ntawv pov thawj yog txwv.
3. Kuaj cov txheej txheem: tawg {{}} eC} Ua daim ntawv pov thawj 50PA, siab poob qis dua lossis sib npaug ntawm 3% tom qab 30 feeb); Intrinsically strellcuit Court parameter ua pov thawj.
IV. Cov kev tiv thaiv kev phom sij
1. Tawg {{- Cov teeb meem pov thawj: zam kev sib qhia ntau qhov hluav taws xob, ploj lawm bolts, lossis cov chaw sib khi.
2. Qhov kev ua kom lub zog siab zoo: Xyuas kom muaj qhov ua tau zoo kiv cua ua haujlwm nquag thiab txiav tawm lub zog thaum lub siab poob qis dua 30PA.
