Kev qhia ua haujlwm ntawm qhov siab thiab tsawg voltage switchgear
Jun 03, 2021
1. Chav chaw tos tsheb loj
Chav chav muab khoom noj yog teem rau sab qaum sab ntawm sab nraub qaum ntawm lub pob hluav taws xob rau kev teeb tsa thiab kev teeb tsa ntawm peb-theem siab voltage AC busbars thiab rau kev txuas nrog cov sib tiv tauj zoo li qub los ntawm ceg busbars. Txhua lub thawv thauj khoom yog cov yas ntim nrog lub ntsej muag insulating. Thaum lub npav tsheb npav dhau los ntawm qhov kev faib tawm ntawm lub txee hloov, nws yog tsau nrog lub npav bushing. Yog tias muaj qhov ua txhaum sab hauv, nws tuaj yeem txo qhov kev sib tsoo ntawm cov xwm txheej mus rau cov txee uas nyob ib sab thiab xyuas kom lub tshuab muaj zog ntawm lub tsheb npav.
2. Lub chav nres hluav taws xob sib tsoo
Cov lus qhia tshwj xeeb kev tsheb nqaj hlau tau teeb tsa hauv chav tsev saib xyuas lub tshuab hluav taws xob rau Circuit Court breaker trolley kom swb thiab ua haujlwm sab hauv. Lub laub txav tuaj yeem txav ntawm txoj haujlwm ua haujlwm thiab qhov chaw sim. Qhov sib faib (cuab) ntawm qhov sib chwv zoo li qub tau muab ntsia rau ntawm phab ntsa tom qab ntawm chav tes chav. Thaum lub laub txav mus los ntawm qhov chaw sim mus rau qhov chaw ua haujlwm, qhov kev faib tawm tau raug qhib, thiab lubcuam tes taw tau txav mus rau hauv qhov kev rov qab mus rau qhov sib xyaw ua ke, yog li xyuas kom tus neeg teb xov tooj tsis kov lub cev raug foob.
3. Cov chav cable
Cov hloov hluav taws xob tam sim no, hloov mus rau hauv av, xob laim taws, tiv thaiv hluav taws xob tiv thaiv, cov thaiv hluav taws xob thiab lwm cov khoom siv tau tuaj yeem ntsia tau rau hauv chav tsev cable, thiab lub rooj zaum rub tawm ntawm txhuas phaj tau npaj rau hauv qab kom ntseeg tau yooj yim ntawm kev tsim kho ntawm chaw.
4. Txav siab rau chav
Lub vaj huam sib luag ntawm chav rov qab yog nruab nrog microcomputer tiv thaiv cov khoom siv, kev ua haujlwm ua haujlwm, tiv thaiv lub qhov hluav taws xob tiv thaiv daim phiaj, meters, ntsuas qhov xwm txheej lossis cov xwm txheej qhia. Chav tsev relay yog nruab nrog lub davhlau ya nyob twg, microcomputer tiv thaiv kev hloov DC lub zog hloov, microcomputer tiv thaiv ua haujlwm DC fais fab khoom siv, thiab chaw cia khoom. Nws tuaj yeem hloov DC lossis AC lub zog ntawm lub cev muaj zog thiab cov khoom siv theem nrab nrog qhov tshwj xeeb.
