Yuav Ua Li Cas Cov Tuam Txhab Qhuav-hom Transformers Ua Cov Kev Ntsuas Kev Ntsuas (2)

1. Tus nqi ntawm cov av tsis kam ntawm qhov kev sim qhuav-hom transformer grounding hlau yog siab dhau. Yog hais tias nws yog nrog los ntawm rwb thaiv tsev puas ntawm cov theem qis-voltage kab thiab grounded, piv txwv li, yog theem A yog grounded, yuav muaj ib tug tam sim no ntws los ntawm qhuav-hom transformer grounding hlau. Qhov voltage ntawm theem A yuav muab ntxiv rau hauv av thiab grounding kuj. Piv txwv tias qhov loj dua qhov kev tiv thaiv hauv av, qhov ntau dua qhov kev faib hluav taws xob ntawm cov av tiv thaiv. Lub sijhawm no, yog tias ib tus neeg yuam kev kov cov xaim hauv av lossis cov xaim nruab nrab ntawm lub tshuab ziab khaub ncaws qhuav, nrog rau lub plhaub ntawm lub tshuab ziab khaub ncaws, tib neeg lub cev yuav tsim ib qho kev sib txuas nrog cov av tiv thaiv, thiab qhov hluav taws xob siv. rau tib neeg lub cev yuav siab heev, ua rau muaj hluav taws xob poob siab.
2. Thaum lub grounding kuj nqi ntawm cov hlau nruab nrab ntawm peb-theem plaub hlau fais fab mov qhuav-hom transformer siab dhau los yog tawg, vim qhov tsis sib xws ntawm peb-theem load, qhov nruab nrab point ntawm qhuav-hom transformer. yuav raug offset, thiab lub peev xwm hauv av yuav tsis yog xoom, ua rau qee theem voltages nce thiab hlawv cov khoom siv hluav taws xob.
3. Thaum tus nqi grounding kuj siab dhau lawm, nws kuj ua rau lub grounding resistance tus nqi ntawm cov qhuav-hom transformer xob laim ntes kom siab dhau. Thaum xob laim overvoltage, lub teeb ntes hluav taws xob tsis tuaj yeem tawm mus rau hauv av ib txwm, ua rau lub teeb ntes hluav taws xob lossis lub tshuab hluav taws xob qhuav hlawv tawm.
