1. Raug manifestations thiab kev pheej hmoo ntawm cov tshuab ua tsis ua tiav
1.1 Ntau dhau los qhib / Kaw lub sijhawm
Cov Qauv Yuav Tsum Tau: Piv txwv li, ABB VM1 Circuit Court cov neeg yuav tsum tau qhib lub sijhawm qhib lub sijhawm tsawg dua lossis sib npaug ntawm 55ms thiab sib npaug li 70ms. Yog tias lub sijhawm qhib tau tshaj li lub Hoobkas muaj nuj nqis los ntawm 10% (xws li ntau dua lossis sib npaug ntawm 38.5ms), nws yuav ncua cov kev sib haum xeeb, ua rau muaj kev ua tiav.
Kev Kawm Txog: Ntawm ib qho kev hloov 500kv, lub sijhawm qhib ncua sijhawm ntawm 42ms tshwm sim kev tiv thaiv backupation, ua rau tag nrho cov chaw nres tsheb tsaus nti ploj ntawm$85,000.
1.2 lub sijhawm sib tiv tauj lub sijhawm
Lub tshuab: Kev co tshuab kev co thaum lub sijhawm kaw ua rau rov ua dua bouncing. Yog lub sijhawm tshaj2ms(Ib tus IEC {62271-100), Hu rau yaig kev nrawm, nrog qhov kub nce siab tshaj 15%.
Kev pom: Use high-voltage switch testers (e.g., Kelm-CI) to record contact travel curves. A bounce amplitude >{{0 {0}}. 5 hli qhia tau tias txawv txav.
1.3 Tshuav Hauv Lub Tshuab
Qho cas: Hauv 2022, ib qho cua ua liaj ua teb txom nyem ib qho kev ua txhaum cai 35kv colution1,200 mwhntawm tiam.
2. Kev kuaj mob: Ntau-seem yuam kev ua txhaum hauv zos
2.1 Kev Ncig Xyuas Lub Sij Hawm Tus Kheej
Kev ua:
Ntsuas txav mus ncig ua si nrog cov ntsuas hluav taws xob siab sensors (daws teeb meem: 0. 1 hli).
Piv nrog Hoobkas curves; Yog tias kev qhib dej ntws tawm ntawm 10% (piv txwv li, los ntawm 4.2m / s rau 3.8m / s), yuav tsum tau saib xyuas tam sim ntawd.
Soj ntsuam cov nqe rooj sib txuas tas li (± {0. 05mm kam rau) thiab ntas roj.
Cov cuab yeej: OMICRON CPC 100 lossis Doble F6150, muaj peev xwm ua rau muaj txiaj ntsig IEEE-raws li kev tshaj tawm.
2.2 coil tam sim no seattormate tsom xam
Kev kuaj mob yuam kev:
Kev kaw ib txwm kaw coil tam sim no peaks ntawm ~ 15a (duration: {{1} ms).
Yog hais tias peak ncua ntau dua20msLos yog cov vervforms qhia pom "Ob chav Peaks" (Daim duab 1), nws qhia tias tseem muaj kev sib tshuam. Cov taw qhia huv huv thiab hloov kua nplua khoom.
Cuab tam: Oscilloscope with ≥10 kS/s sampling rate and >100kHz bandwidth (piv txwv li, tuav tseg dsox1204a).
2.3 Kev co kos duab soj ntsuam
Cov tswv yim tseem ceeb:
Nruab triaxial lub nrawm nrawm (zaus ntau yam: {{{}}} cme khz) ntawm kev ua haujlwm vaj tse.
Thov wavelet hloov pauv (DB4 hauv paus) rau denOe thiab rho tawm cov xeeb ceem ntau zaus (piv txwv li {{1} hz qhia los ntawm lub zog hluav taws xob).
Abnormal vibration energy >50mv / g qhia cam coj los yog iav misalignment.
Rooj plaub: Ib lub tshuab roj petrochemical ntes tau lub caij nplooj ntoo hlav Quav Qoob Luv Tawm ntawm Online Kev co tshuaj xyuas 7 hnub ua ntej, zam$320,000nyob rau hauv unplanned downtime.
2.4 SF6 roj roj ceev soj ntsuam
Threshold: Ntawm 20 degree, yog sf6 siab poob{{0 {0}}. 02 MPa hauv qab tus nqi(Xws li, lub tswb ntawm {{{{0}}}
Kev kuaj kom tau: Siv cov ntsuas laser dej xau (rhiab heev: 1ppmatan ·) txhawm rau scan flange ntsaws ruaj ruaj. Hloov cov O-Rings (Rings (Vitoroelasomer pom zoo) yog tias tsis tshaj{{0 {}}. 5% / xyoo.
3. Kev tiv thaiv kev ntsuas: Kev tswj lub sijhawm puv nkaus
3.1 ib puag ncig huab kev yoog
Huab cua huab cua txias huab cua: Rau qhov kub<-20°C, verify heater power ≥200W and use low-temperature grease (e.g., Mobilgrease XHP 461, pour point: -45°C).
Rooj plaub: Ib qho kev hloov pauv hauv sab hauv Mongolia tau txais kev lom zem rau roj ua tsis tau zoo vim muaj lub sijhawm ua haujlwm, nce sijhawm ntawm 32ms rau 58ms. Kev ua haujlwm ib txwm rov pib dua tom qab hloov chaw.
3.2 Cov Khoom Tiv Thaiv Cheeb Tsam
Lub Caij Nplooj Ntoos Hlav: Lub lim piam tiv thaiv ib zaug corrosion; Siv Molybdenum Disulfide Chruant (50-80 μm tuab) mus khawm. Kev ntsuas ntsev yuav tsum tsis pom480 teev yam tsis xeb.
Arc Chambers: Yuav tsum tau hloov chaw Nozzle hloov (PTFE / tooj-tungsten Composite) tom qab2, {{000 kev ua haujlwm lossis 10 qhov kev cuam tshuam luv-circuit txwv(Per IEEE C37.09).
3.3 Cov khoom hloov tshiab
Cov Txiaj Ntsig Xyuas Kev Kho Mob (CMS): Sib xyaw ua ke cov neeg kho tshuab tsis muaj roj, roj ceev, thiab kub, siv AI kom kwv yees lifespan) (<5% error).
Kev Kho Chaw Taws Teeb: 4G / 5G Cov Ntaub Ntawv Kis Los Huab Cua Los Siv Tsis Siv Neeg Lub Cim Hluav Taws Xob (piv txwv li, f} "
4. Kws muaj txuj pom zoo
Testing Team:
Cov Kev Hloov Hloov Tshiab: Puv Ntsuam Xyuas Txhua 3 hlis rau thawj xyoo.
Breakers >5 xyoo dhau los: txhua hli chev tam sim no thiab kev co ntsuas.
Kev Tswj Xyuas Qhov Chaw: Tshuag ntau dua lossis sib npaug ntawm 2 lub tshuab ua haujlwm thiab 10% ntawm cov neeg siv khoom (piv txwv li, cov ntsaws ruaj ruaj hloov hauv4 teev.
Kev Txhawb Nqa: Rau cov phiaj xwm txij nkawm lossis cov cim kev kuaj mob, hu rau
