Morteng grounding carbon txhuam yog cov khoom tseem ceeb hauv kev sib hloov lub cev muaj zog (xws li cov tshuab hluav taws xob thiab cov tshuab hluav taws xob), feem ntau yog siv los tshem tawm cov ncej tam sim no, tiv thaiv cov cuab yeej kev nyab xeeb, thiab pab saib xyuas cov tshuab. Lawv daim ntawv thov scenarios thiab functions yog raws li nram no:
I.Core Functions and Effects
- Thaum lub tshuab hluav taws xob lossis lub cev muaj zog khiav, qhov tsis sib xws hauv qhov chaw sib nqus (xws li qhov tsis sib xws ntawm huab cua lossis qhov sib txawv ntawm cov coil impedance) tuaj yeem ua rau lub zog hluav taws xob hauv lub rotating ncej. Yog hais tias tus ncej hluav taws xob tawg los ntawm cov kabmob roj zaj duab xis, nws tuaj yeem tsim cov ncej tam sim no, ua rau cov ncej bearing electrolysis, lubricant degradation, thiab txawm tias cov kabmob tsis ua haujlwm.
- Morteng grounding carbon txhuam luv luv-circuit lub rotor ncej mus rau lub tshuab vaj tse, hloov cov ncej tam sim no mus rau hauv av thiab tiv thaiv lawv los ntawm ntws los ntawm cov bearings. Piv txwv li, cov tshuab hluav taws xob loj feem ntau nruab cov pa roj carbon txhuam hauv qhov kawg ntawm lub turbine kawg, thaum lub sij hawm excitation kawg bearings yog haum nrog insulating pads, tsim cov classic 'excitation kawg rwb thaiv tsev + turbine kawg grounding' configuration.
II. Hom Daim Ntawv Thov Scenarios
-Thermal/hydropower generators: Morteng grounding carbon txhuam yog ntsia rau ntawm lub turbine kawg, ua ke nrog insulated bearings ntawm excitation kawg, kom tshem tawm cov hluav taws xob sib nqus induction ncej voltage. Piv txwv li, nyob rau hauv hydropower generators, thrust bearings cia siab rau ib tug nyias roj zaj duab xis rau rwb thaiv tsev, thiab grounding cov pa roj carbon txhuam yuav tiv thaiv electrolysis ntawm bearing shells.
- Cua turbines: Siv rau lub tshuab hluav taws xob rotors lossis kev tiv thaiv hluav taws xob, cov khoom siv feem ntau raug xaiv los ntawm cov hlau graphite (tooj liab / nyiaj-raws li), uas muaj cov khoom siv hluav taws xob siab, hnav tsis kam, thiab kev tiv thaiv tam sim no.
-High-voltage/variable-frequency motors: Cov no muaj kev pheej hmoo siab dua ntawm cov ncej tam sim no. Piv txwv li, Tonghua Lub Tuam Txhab Tsim Hluav Taws Xob tau teeb tsa cov pa roj carbon txhuam rau ntawm qhov kawg ntawm tus kiv cua lub cev muaj zog, siv cov twj tso kua mis tsis tu ncua kom muaj lub peev xwm xoom, yog li daws qhov teeb meem uas cov thawj insulated bearings tsis tuaj yeem thaiv cov ncej tam sim no.
-Railway tsheb thauj mus los: Nyob rau hauv traction motors ntawm hluav taws xob locomotives los yog diesel locomotives, grounding carbon txhuam tshem tawm cov hluav taws xob zoo li qub thaum lub sij hawm ua hauj lwm, tiv thaiv bearings, thiab tswj hluav taws xob system stability.
