Cov kab hluav taws xob siv hluav taws xob ua lub luag haujlwm tseem ceeb hauv kev thauj mus los ntawm lub zog, suav nrog ntau yam khoom xws li kab yees, conductors, thiab insulators. Paub txog qib voltage ntawm cov kab no yog qhov tseem ceeb rau kev saib xyuas thiab kev nyab xeeb. Cov insulators, txawm iav, ceramic, los yog composite, muab hluav taws xob rwb thaiv tsev thiab ncaj qha cuam tshuam kab kev ua tau zoo.
Ib txoj hauv kev zoo los txheeb xyuas cov qib voltage yog los ntawm kev tshuaj xyuas cov txheej txheem ntawm cov insulators. Tus naj npawb ntawm cov insulators nyob rau hauv ib txoj hlua sib txuas nrog rau qib voltage. Nov yog phau ntawv qhia ceev:
| Tus naj npawb ntawm insulators / thooj | Qhov ntev ntawm cov insulator / m | voltage /kv |
| 3-5 | 0.7 | 35 |
| 7-9 | 1.3 | 110 |
| 13-15 | 2.2 | 220 |
| 17-20 | 3 | 330 |
| 25-31 | 5 | 500 |
| 32-38 | 6.5 | 750 |
Txog 35KV Kab:
Siv tus pin insulator.
35KV kab:
Tsis pub tsawg tshaj 5 insulators nyob rau hauv ib txoj hlua.
60KV kab thiab saum toj no:
Tus naj npawb ntawm cov insulators nce nrog ntau dua voltage.
Composite insulators, nrog lawv cov yam ntxwv siab heev, tau nyiam dua hauv cov tshuab hluav taws xob niaj hnub no. Lawv txhim kho kev ua tau zoo thiab ua kom ntseeg tau kev xa hluav taws xob. Nyob twj ywm rau kev nkag siab ntau ntxiv rau hauv lub ntiaj teb muaj zog hluav taws xob!
