Hwj huam zoo

Hwj huam zoo

Ntau yam teeb meem yuav ua los ntawm cov hwjchim tsis zoo, tshwj xeeb tshaj yog nyob rau hnub no txoj microelectronics. Yav tag los, hluav taws xob disturbances rau mechanical khoom mus unnoticed. Tam sim no, tsis tas li ntawd, hluav taws xob disturbances yuav chim hnub no lub high-tech khoom haujlwm loj heev.

Kwv yees li ntawm 80 feem pua ntawm cov hwjchim zoo keeb kwm ntawm tus neeg sab nrauv hais txog lub meter. Nws tseem ceeb heev rau cov tswv tsev, tswj, designers thiab lwm cov neeg siv high-tech cov neeg siv to taub thiab kawm kom tsis txhob muaj hwj huam disturbances. Ntsuam xyuas cov nram qab no rau ib tug general overview ntawm cov hwjchim zoo:

Hwj huam zoo thiab voltage stability

Nws yog ib qho zoo rau koj cov hluav taws xob voltage los sib txawv nyob rau hauv cov ntaub ntawv txwv. Cov fluctuations no yuav ua tau los ntawm lub lag luam ntawm lub chaw tso dej fais fab tuag thiab tis lawv, ntawm lwm yam. Cov kev hloov no yuav tsis ua teeb meem rau koj cov khoom los yog tej chaw. Tej yam khoom siv hauv hluav taws xob tej zaum yuav rhiab heev rau cov fluctuations, tsis tas li ntawd, uas tej zaum yuav ua teeb meem.

Koj yog lub luag hauj lwm los muab tej li yuav tsum tau tiv thaiv koj rhiab khoom uas tsis tau khiav lag luam nyob rau hauv lub voltage variations ntawm peb cov kev pab cuam hluav taws xob. Hluav taws xob txoj cai 2, rau cov ntaub ntawv nrog rau California Public Utilities Commission, specifies cov variations. PG& E tsis yog liable rau koj cov khoom los yog lwm yam kev puas tsuaj los ntawm variations nyob rau hauv qhov kev pab cuam voltage uas nyob rau hauv txoj cai no.

Hwj huam zoo

Hwj huam zoo teeb meem arise thaum lawv incompatibility tshwm sim ntawm lub HWJ HUAM AC thiab cov khoom. Xws li qhov zoo tshaj ntawm cov AC distribution lawv los yog cov AC voltage yuav ua rau muaj teeb meem zoo. Yuav kom nrhiav tau cov tshuaj los yog tov, nws tseem ceeb heev uas yuav tau tshawb xyuas cov teeb meem kom yog. Ib txhia raug fais fab zoo yog:

• Txheej txheem yuam kev
• Soft failures xws li lub computer reset los yog lockout
• Nyuaj tsis ua hauj lwm ntawm electronic components
• Nuisance tripping nyob rau hauv cov khoom tswj cov khoom

Analyze fais fab zoo

Thaum analyzing ib tug neeg hwj huam zoo, nws tseem ceeb heev uas yuav tau khaws ib tug teeb meem log. Qhov no yuav pab txuas qhov teeb meem rau lwm yam txheej xwm xws li khoom ua haujlwm los yog txawm tias cov teeb meem. Xyuas SEB PG&E tus "Checklist los daws teeb meem rau rhiab khoom" pab qhia thiab mitigate fais fab teeb meem rau rhiab khoom.

Cov checklist muaj lus nug txog koj yuav tsum teb nyob rau hauv koj cov teeb meem log kom paub tseeb tias ua tau thiab tov. Thaum koj twb kuaj tau qhov teeb meem (e.g., voltage sags, outages, impulses, harmonics, hluav taws xob nrov, voltage thiab tam sim no imbalances, cuam tshuam los yog wiring thiab grounding, etc.) kom yog, koj yuav tiv thaiv tau kev ntsuas los mitigate qhov teeb meem. Tej zaum cov tshuaj yuav yooj yim li kho koj cov khoom kom nws rhiab rhiab rau cov hwjchim variations. Nco ntsoov kho nyob rau hauv ib tug txiv neej uas tsis void tej warranties.

Hwj huam Notes

Peb PG& E hwj huam Notes rau hauv qab no tej zaum yuav pab koj paub thiab daws tau koj cov teeb meem zoo los yog kev txhawj xeeb.

Hwj huam zoo Bulletins

PG& E lub hwj huam zoo Bulletins kuj yuav pab koj paub thiab daws tau koj cov teeb meem zoo los yog kev txhawj xeeb.
