FZRN21-12D Nqus Load So Hloov Thiab Fuse thaum lawv tseem Apparatus
hauj lwm:
FZRN21-12D sab hauv tsev nqus load so mus thiab fuse ua ke apparatus siv rau lub hwj chim system ntawm nyob voltage 12kV, AC 50 / 60Hz. Nws muab hwj chim, tswj thiab tiv thaiv hluav taws xob apparatus. Lub apparatus hloov kim Vcb rau kev pab nyob rau hauv hluav taws xob network. Nws kuj yuav siv tau nyob rau hauv uas nyob deb nroog thiab hauv nroog fais fab mov systems mus ua txhaum thiab ua nyob rau hauv cov movies tam sim no thiab luv luv- Circuit Court tam sim no thaum lub Circuit Court lov. Nws tseem yog muaj feem xyuam rau tswj thiab tiv thaiv transformers.

FZRN21-12D Nqus Load So Hloov thiab Fuse thaum lawv tseem Apparatus
Cov load-tawg hloov yog ib tug QHAIB ntaus ntawv ntawm peb-
theem. The Vcb is ua los ntawm hluav taws xob caij nplooj ntoos hlav los yog Covendent phau ntawv no. Thyognbsp;qhib lag luam is ntawm ob qho tib si dependent phau nnyob;thiab dependent hwj chim.
Muaj yog txhim khu kev qha QHAIB ntawm lub tshuab nqus tsev arc-tua chamber, disconnect hniav thiab grounding hniav. thaum the fuse so cia, the&nlub;load-
tawg switch qhib los ntawm the QHAIB mechanism. Cov load so shloovnbsp;tau yuav mounted nyob rau hauv Switchgear thiab dai-olubbsp;the phab ntsa rau
tiv thaiv transformers.
