Feem ntau txawv txav ntawm tam sim no Transformers
Nov 21, 2022| Thaum peb siv lub tshuab hluav taws xob tam sim no, peb-theem hluav taws xob tsuas yog tsis sib npaug, thiab thaum ib theem txo qis, ob theem yog qhov qub heev thiab cov kab hluav taws xob tsis zoo los yog nrog lub suab thiab lub teeb pom kev zoo. Hauv qhov no, nws muaj feem ntau tias nws yog kev sib nrig sib inductance. Nws yog tau hais tias lub high-voltage los yog low-voltage fuse ntawm lub cuab yeej tau tshuab.
Thaum peb muaj cov txheej txheem hauv av zoo heev ntawm qhov nruab nrab ntawm qhov nruab nrab thiab qhov peb-theem voltage qhia tau hais tias qhov tsis sib npaug ntawm ib theem poob tab sis lwm ob theem nce los yog lub pointer viav vias, ces tej zaum yuav muaj qhov txhaum lossis qhov tseem ceeb zaus resonance thaum ib theem. yog grounded tab sis Yog hais tias peb-theem voltage nce nyob rau tib lub sij hawm thiab tshaj cov kab hluav taws xob, nws yuav tshwm sim vim muaj zaus division los yog high zaus resonance.
Yog hais tias lub high-voltage fuse yog cua tshuab ntau zaus, nws yuav zoo li hais tias ib feem ntawm lub rwb thaiv tsev ntawm cov cuab yeej raug puas lawm, xws li luv luv Circuit Court ntawm winding txheej los yog lem, thiab lwm yam yog ib tug zoo heev nruab nrab grounding system. . Thaum lub busbar raug kaw, theem voltage nce thiab oscillates ntawm ib tug tsawg zaus, uas yog feem ntau yog ib tug tshwm sim ntawm series resonance. Thaum lub sij hawm voltage dheev nce los yog ntog txawv txav, nws yog zoo li hais tias lub transformer yog nyob rau hauv insulated. Kev puas tsuaj, piv txwv li, yog qhov ua txhaum ntawm kev txhawb nqa insulating thiab luv luv ntawm cov khaubncaws sab nraud povtseg lossis nruab nrab ntawm cov lem.
Yog hais tias lub voltage transformer nyob rau hauv nruab nrab point ranger lub grounding system qhia tau hais tias tsis ruaj tsis khov heev ntawm lub voltmeter thaum nws muab tso rau hauv lub lag luam, tej zaum nws yuav hais tias qhov kev sib cuag ntawm high-voltage winding kawg yog tsis zoo thaum nws yog grounded. Nws yooj yim heev rau tus kheej hem.
