Yuav Ua Li Cas Thiaj Li Tsawg -Voltage Switchgear kom ncua nws txoj sia

Tus yuam sij rau kev ncua lub neej ntawm qis -voltage switchgear yog nyob rau hauv kev saib xyuas. Kev tu tsis tu ncua, nruj kev sib txuas, kev ntsuas rwb thaiv tsev, thiab kev ua haujlwm pov thawj tuaj yeem tiv thaiv kev ua yuam kev thiab txhim kho kev ua haujlwm ruaj khov. Nrog kev saib xyuas kom zoo, cov cuab yeej siv lub neej ruaj khov tuaj yeem ncav cuag 15 txog 20 xyoo lossis ntev dua.

 

Kev tshuaj xyuas txhua hnub (pom zoo txhua hnub lossis txhua lub limtiam)

Environmental thiab Visual Inspection

Xyuas kom muaj qhov cua zoo hauv chav faib khoom, nrog qhov kub tsawg dua lossis sib npaug li 40℃thiab av noo tsawg dua lossis sib npaug li 90% yam tsis muaj condensation.

Tshawb xyuas lub txee rau deformation, xeb, thiab txheej txheej txheej. Xyuas kom lub qhov rooj vaj huam sib luag kaw kom nruj kom tsis txhob muaj plua plav, noo noo, lossis tsiaj me nkag mus.

Mloog txhua lub suab txawv txav (xws li lub suab tawm lossis kev vibrations). Saib seb cov twj paj nruag thiab qhov taw qhia teeb ua haujlwm li cas.

Ntxuav thiab tshem tawm plua plav

Siv ib daim ntaub qhuav, mos los yog lub tshuab nqus tsev ntxhua khaub ncaws kom tshem tawm cov plua plav tawm ntawm sab hauv thiab sab nraud ntawm lub txee, ua tib zoo saib xyuas cov qhov cua qhov, busbars, thiab insulator qhov chaw.

Tsis txhob siv cov ntaub ntub dej los yog cov tshuaj ntxuav corrosive los tiv thaiv luv luv Circuit Court lossis cov khoom puas.

Kos Npe thiab Cov Cuab Yeej Thaum Muaj Xwm Ceev

Txheeb xyuas tias cov cim ceeb toom, cov paib saib xyuas, thiab cov cim khawm ua haujlwm yog qhov tseeb thiab raug tso.

Paub meej tias lub teeb thaum muaj xwm ceev, crank handles, fuse handles, thiab lwm yam, yog tiav thiab siv tau.

 

Kev Saib Xyuas Tsis tu ncua (pom zoo txhua 3-6 lub hlis)

Hluav taws xob txuas Tightening

Xyuas kom meej tias cov bolts txuas busbars, cable sib txuas, cov davhlau ya nyob twg, thiab lwm yam, yog xoob. Tighten lawv mus rau tus qauv torque siv lub torque wrench.

Saib xyuas cov ntsiab lus sib cuag rau qhov kub dhau los yog xim daj (nyiaj -dawb yog qhov qub; blackening lossis discoloration yuav tsum tau kho).

Rwb thaiv tsev Performance Test

Tom qab fais fab tuag lawm, siv lub megohmmeter los ntsuas theem - mus rau -theem thiab theem - mus rau - av rwb thaiv tsev. Nws yuav tsum ntau dua los yog sib npaug rau 1MΩ.

Tshawb xyuas cov khoom siv rwb thaiv tsev rau cov kab nrib pleb, kev laus, lossis cov cim tawm.

 

Functional Component Inspection

Breaker: Manually qhib thiab kaw lub Circuit Court 3 zaug los xyuas nws cov neeg kho tshuab kev ua tau zoo rau kev yooj thiab kev ncaj ncees ntawm lub arc extinguishing chamber.

Contactor/Relay: Xyuas cov neeg rau oxidation los yog ablation; Lub coil kub yuav tsum tsis txhob siab tshaj 65 degree.

Capacitor txee: Tom qab disconnecting lub ntsiab hloov, tso tawm txhua lub capacitor ib tug los ntawm ib tug, tshuaj xyuas rau bulging, to, thiab txhim khu kev qha grounding.

Ntxuam thiab cua txias system

Xyuas seb lub txee ntxuam ua haujlwm li cas thiab yog tias cov vents raug thaiv. Ntxuav lossis hloov lub lim yog tsim nyog.
