Ua haujlwm kev nyab xeeb tshuab ntawm cov khoom siv vuam tshuab

1. Cov neeg ua haujlwm welder yuav tsum tau txais kev cob qhia kev nyab xeeb, kev soj ntsuam, thiab ua haujlwm nrog cov ntawv pov thawj.

2. Nws tsis raug tso cai ua haujlwm hauv huab cua qhib thaum huab cua los nag, daus thiab cua zog qib 6 lossis siab dua (nrog rau qib 6). Tom qab los nag thiab daus, cov tsub zuj zuj thiab daus yuav tsum tau muab tshem tawm ua ntej ua haujlwm.

3. Cov khoom tawg thiab tawg yuav tsum tsis txhob muab tso rau hauv 10m ib ncig ntawm qhov chaw vuam.

4. Hnav cov khaub ncaws ua haujlwm, cov khau insulating, hnab looj tes rau qhov chaw vuam tshuab, tiv thaiv lub ntsej muag, tsom iav thiab lwm yam khoom siv tiv thaiv thaum ua haujlwm, thiab hnav txoj siv sia thaum ua haujlwm siab.

5. Kev siv cov khoom siv vuam tshuab yuav tsum tau ua raws li cov cai hauv qab no:

(1) Kev teeb tsa, kho thiab tshuaj xyuas cov khoom siv vuam yuav tsum tau ua los ntawm cov kws tshaj lij. Thaum lub vuam tshuab thiab kab tsis ua haujlwm, lub zog yuav tsum raug txiav tam sim ntawd thiab tus kws kho hluav taws xob yuav tsum tau ceeb toom rau kev kho.

(2) Lub tshuab hluav taws xob xa hluav taws xob hloov pauv thiab cov khoom siv tiv thaiv ntawm qhov chaw vuam tshuab yuav tsum muaj kev nkag siab thiab siv tau zoo, thiab cov xaim hluav taws xob yuav tsum zoo.

(3) Kev ua haujlwm ntawm AC qhov chaw vuam tshuab yuav tsum tau ua raws li cov kev cai hauv qab no: peb-theem load yuav tsum sib npaug thaum txuas ntau lub tshuab vuam, thiab yuav tsum muaj qhov hloov pauv thiab fuse tiv thaiv ntawm thawj kab. Qhov chaw vuam tshuab yuav tsum tau zoo insulated. Lub rwb thaiv tsev tiv thaiv ntawm thawj coil winding thiab theem nrab coil winding ntawm vuam transformer thiab nruab nrab ntawm winding thiab casing yuav tsum tsis pub tsawg tshaj 1MΩ. Lub tshuab welding qhov chaw yuav tsum tau nruab nrog lub npog tiv thaiv rau kev xaim ntawm cov xov hlau tseem ceeb thiab theem nrab. Kev ua haujlwm ntawm qhov chaw vuam tshuab yuav tsum ua raws li cov qauv tsim thiab yuav tsum tsis txhob overloaded. Thaum lub sijhawm ua haujlwm, qhov kub ntawm qhov chaw vuam tshuab yuav tsum tau kuaj xyuas ntau zaus, thiab kev ua haujlwm yuav tsum tau nres thaum qhov kub siab tshaj 60 degree rau Class A thiab 80 degree rau Class B.

(4) Ua ntej siv lub tshuab welding, cov rwb thaiv tsev thiab cov hlua yuav tsum tau kuaj xyuas, thiab cov hlua yuav tsum tsis txhob corroded, damped los yog xoob.

(5) Cov hlua hluav taws xob ntawm qhov chaw vuam tshuab yuav tsum tau zoo insulated thiab qhov ntev yuav tsum tsis txhob siab tshaj 5m.

(6) Lub tshuab vuam tshuab yuav tsum tau muab tso rau hauv qhov cua zoo, qhuav, tsis muaj corrosive nruab nrab, kom deb ntawm qhov kub thiab txias, av noo thiab plua plav. Lub tshuab vuam siv nyob rau hauv cov huab cua qhib yuav tsum tau nruab nrog ib tug los nag vaj tse, lub vuam tshuab yuav tsum tau padded nrog insulating cov ntaub ntawv, thiab qhov siab ntawm padded yuav tsum tsis txhob tsawg tshaj li 20cm, thiab cov khoom siv tua hluav taws yuav tsum tau muab raws li qhov xav tau.

(7) Sab hauv ntawm qhov chaw vuam tshuab yuav tsum tau ua kom huv si, thiab cov plua plav yuav tsum tau tshuab tsis tu ncua. Lub hwj chim yuav tsum tau muab tua thaum ntxuav.

(8) Lub plhaub ntawm qhov chaw vuam tshuab yuav tsum muaj kev tiv thaiv kev ruaj ntseg rau xoom kev sib txuas. Kev tiv thaiv xoom kab ntawm qhov chaw vuam tshuab yuav tsum tau kuaj xyuas tsis tu ncua.

(9) Tom qab qhov chaw vuam tshuab tau pib, nws yuav tsum khiav tsis muaj kev thauj khoom rau lub sijhawm. Kho cov vuam tam sim no thiab lub polarity hloov yuav tsum tau nqa tawm nyob rau hauv tsis muaj load. Qhov tsis muaj qhov hluav taws xob ntawm DC vuam tshuab yuav tsum tsis pub tshaj 90V, thiab qhov tsis muaj qhov hluav taws xob ntawm AC vuam tshuab yuav tsum tsis pub tshaj 80V.

(10) Lub vuam cable ntawm qhov chaw vuam tshuab yuav tsum siv ntau txoj hlua hlau nyias nyias, thiab nws cov ntu ntu yuav tsum raug xaiv raws li qhov yuav tsum tau ua ntawm qhov chaw vuam tshuab. Lub cable sheath yuav tsum zoo thiab mos, thiab nws cov rwb thaiv tsev yuav tsum tsis txhob tsawg tshaj li 1MΩ. Qhov ntev ntawm lub vuam cable yuav tsum tsis pub tshaj 30m.

(11) Lub tshuab vuam qhov chaw yuav tsum tau nruab nrog lub zog hloov pauv thiab tsis siv neeg lub hwj chim tawm. Lub tshuab hluav taws xob hloov hluav taws xob thiab lub tshuab hluav taws xob tsis siv neeg yuav tsum tau muab tso rau hauv lub thawv los nag los tiv thaiv, ntsia rau hauv qhov chaw uas yooj yim rau kev khiav lag luam, thiab sab laug nrog kev nyab xeeb.
