Dab tsi yog Peb Qhov Tseem Ceeb Ntawm Switchgear?

Taw qhia

Switchgear tuaj yeem txhais tau tias yog lub tshuab hluav taws xob siv los tswj, tiv thaiv thiab cais cov khoom siv hluav taws xob. Nws yog ib qho tseem ceeb ntawm lub zog hluav taws xob thiab muaj peev xwm hloov thiab faib hluav taws xob hluav taws xob. Muaj ntau ntau hom switchgear thiab hauv tsab xov xwm no, peb yuav tham txog peb yam tseem ceeb.

Part 1: Air-insulated switchgear (AIS)

AIS yog hom hloov pauv ntau tshaj plaws thiab tau siv ntau xyoo. Raws li lub npe qhia, hom switchgear no siv cua ua qhov nruab nrab insulating. Nws yog feem ntau siv hauv cov ntawv thov hluav taws xob tsawg thiab nruab nrab.

AIS yog tsim los ntawm ntau yam xws li cov hluav taws xob hluav taws xob, hluav taws xob hloov hluav taws xob, cov hloov hluav taws xob hauv av, tam sim no transformers thiab voltage transformers. Circuit Court breakers yog siv los cuam tshuam tam sim no nyob rau hauv cov ntaub ntawv ntawm ib tug ua txhaum thiab disconnect keyboards yog siv los cais cov khoom. Grounding keyboards yog siv rau cov khoom siv hauv av thiab tiv thaiv kev tiv thaiv hluav taws xob thaum tam sim no thiab voltage transformers yog siv los ntsuas tam sim no thiab voltage feem.

Muaj ntau qhov zoo rau kev siv AIS suav nrog nws txoj kev yooj yim, kev ntseeg tau thiab kev saib xyuas qis. Txawm li cas los xij, nws muaj qee qhov tsis zoo nrog rau nws qhov loj me thiab xav tau kev saib xyuas tsis tu ncua los tiv thaiv corrosion.

Part 2: Gas-insulated switchgear (GIS)

GIS yog ib hom kev hloov pauv uas siv cov roj sulfur hexafluoride (SF6) ua qhov nruab nrab insulating. Nws feem ntau yog siv nyob rau hauv high voltage daim ntawv thov thiab yog compact dua AIS.

GIS yog tsim los ntawm ntau yam xws li cov hluav taws xob hluav taws xob, hluav taws xob hloov hluav taws xob, cov hloov hluav taws xob hauv av, tam sim no transformers thiab voltage transformers. Circuit Court breakers yog siv los cuam tshuam tam sim no nyob rau hauv cov ntaub ntawv ntawm ib tug ua txhaum thiab disconnect keyboards yog siv los cais cov khoom. Grounding keyboards yog siv rau cov khoom siv hauv av thiab tiv thaiv kev tiv thaiv hluav taws xob thaum tam sim no thiab voltage transformers yog siv los ntsuas tam sim no thiab voltage feem.

Muaj ntau qhov zoo rau GIS suav nrog nws qhov loj me, kev ntseeg siab thiab kev saib xyuas qis. Txawm li cas los xij, nws muaj qee qhov tsis zoo nrog rau nws cov nqi siab thiab xav tau cov cuab yeej tshwj xeeb los tswj thiab kho nws.

Part 3: Hybrid switchgear

Hybrid switchgear yog ib hom switchgear uas sib txuas qhov zoo ntawm ob qho tib si AIS thiab GIS. Nws siv qhov sib xyaw ntawm huab cua thiab SF6 roj raws li qhov nruab nrab insulating thiab feem ntau yog siv rau hauv cov ntawv thov hluav taws xob siab.

Hybrid switchgear yog tsim los ntawm ntau yam xws li Circuit Court breakers, disconnect keyboards, grounding switches, tam sim no transformers thiab voltage transformers. Circuit Court breakers yog siv los cuam tshuam tam sim no nyob rau hauv cov ntaub ntawv ntawm ib tug ua txhaum thiab disconnect keyboards yog siv los cais cov khoom. Grounding keyboards yog siv rau cov khoom siv hauv av thiab tiv thaiv kev tiv thaiv hluav taws xob thaum tam sim no thiab voltage transformers yog siv los ntsuas tam sim no thiab voltage feem.

Muaj ntau qhov zoo rau kev siv hybrid switchgear nrog rau nws qhov loj me, kev ntseeg siab thiab kev saib xyuas qis. Nws kuj muaj peev xwm ua haujlwm nyob rau hauv qhov kub thiab txias thiab ib puag ncig hnyav. Txawm li cas los xij, nws muaj qee qhov tsis zoo nrog rau nws cov nqi siab thiab qhov yuav tsum tau ua tib zoo saib xyuas cov roj SF6.

Xaus

Hauv kev xaus, switchgear plays lub luag haujlwm tseem ceeb hauv lub zog hluav taws xob thiab muaj ntau hom kev xaiv los ntawm. Peb hom tseem ceeb yog cua-insulated switchgear, roj-insulated switchgear thiab hybrid switchgear. Txhua hom muaj nws qhov zoo thiab qhov tsis zoo thiab kev xaiv yog nyob ntawm daim ntawv thov tshwj xeeb thiab cov kev xav tau. Nws yog ib qho tseem ceeb kom ua tib zoo xav txog txhua yam ua ntej xaiv ib hom switchgear rau ib daim ntawv thov tshwj xeeb.
