Kev tu thiab kho ntawm qis-Voltage Switchgear

Lub hauv paus tseem ceeb ntawm qis -voltage switchgear txij nkawm thiab kev tu vaj tu tsev yog kev tshuaj xyuas tsis tu ncua, ntxuav thiab tshem tawm plua plav, kev sib txuas kom nruj, thiab kev ntsuas rwb thaiv tsev thiab kev ua haujlwm kom ruaj ntseg thiab ruaj khov cov khoom siv. Kev saib xyuas kom zoo tuaj yeem tiv thaiv kev ua haujlwm tsis zoo, txuas ntxiv cov cuab yeej siv lub neej, thiab ua kom lub zog txuas ntxiv.

 

Kev Saib Xyuas Txhua Hnub (Txhua Hnub / Lub Limtiam Kev Pom Zoo)

Cov tsos mob thiab kev soj ntsuam ib puag ncig

Tshawb xyuas lub txee rau deformation, corrosion, lossis txheej txheej. Xyuas kom lub qhov rooj ntsaws ruaj ruaj kom tsis txhob muaj plua plav thiab ya raws.

Xyuas kom lub chaw khiav hauj lwm kub tsawg dua los yog sib npaug li 40 degree, av noo tsawg dua los yog sib npaug li 90% tsis muaj condensation, qhov cua zoo, thiab tsis muaj kev pheej hmoo ntawm cov dej to los yog cov tsiaj me me.

Mloog cov suab txawv txav hauv lub txee (xws li cov suab nrov tawm lossis lub suab vibration), thiab saib seb cov twj paj nruag thiab cov teeb pom kev ua haujlwm zoo 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 tshuaj ntxuav corrosive los tiv thaiv kev puas tsuaj rau cov khoom siv hluav taws xob.

Labeling thiab Tool Check

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 cov cuab yeej thaum muaj xwm ceev, lub teeb, crank handles, fuse handles, thiab lwm yam, yog ua 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

Circuit Breaker: Manually qhib thiab kaw lub Circuit Court breaker 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.
