Txhob Them Nyiaj rau Blown Transformers: Vim Li Cas Txhua Lub Pauv -Mounted Unit Xav Tau Tam Sim No -Tam sim no txwv cov fuse tam sim no

Txhua xyoo, cov khoom siv hluav taws xob, cov chaw tsim khoom lag luam, thiab cov tuam tsev lag luam tau ntsib kev tsis txaus siab txog kev hloov pauv. Lub hauv paus feem ntau yog dab tsi? Tsis txaus luv luv- tiv thaiv Circuit Court- tshwj xeeb, kev siv dav dav - lub hom phiaj fuses es tsis txhob siv tam sim no - txwv cov fuses thaub qab.

Pad-mounted transformers muaj cov yam ntxwv tshwj xeeb: cov qauv compact, tsawg thermal muaj peev xwm, thiab kev ua haujlwm tsis muaj neeg saib xyuas, ua rau lawv nkag siab rau lub zog ua txhaum.

General -Lub hom phiaj fuses uatsis yogtiv thaiv transformers. Kev khiav hauj lwm ceev ntawm ib tug dav - lub hom phiaj fuse yog 1/2 lub voj voog (kwv yees li 8 milliseconds). Hauv 8 milliseconds no, luv luv -circuit tam sim no surges los ntawm transformer windings zoo li lub tsheb ciav hlau khiav.

Vim li cas tam sim no muaj peev xwm - txwv cov thaub qab fuses tiv thaiv transformers?

Tam sim no - txwv tsis pub thaub qab fuses tau ntim nrog siab -purity quartz xuab zeb. Thaum ib tug luv luv Circuit Court tshwm sim, lub fuse caij vaporizes nyob rau hauv1-2 milliseconds, thiab hluav taws xob arc yog nruj nreem kaw los ntawm quartz xuab zeb.

General-lub hom phiaj fuse=airbag (xa tawm tsuas yog tom qab cuam tshuam; kev puas tsuaj tseem tshwm sim)

Tam sim no - txwv tsis pub thaub qab fuse=tsis siv neeg nres nres (nres ua ntej kev sib tsoo; tsis muaj kev cuam tshuam tag nrho)
