Yuav tiv thaiv lub hwj chim transformer los ntawm xob laim?
Lub zog hloov hluav taws xob peb feem ntau siv qee zaum muaj hluav taws xob puas tsuaj hauv cov khoom siv hluav taws xob xaim hluav taws xob thaum muaj cua daj cua dub, feem ntau yog vim lub overvoltage ntawm kev hloov mus rau pem hauv ntej thiab thim rov qab thaum lub zog faib hluav taws xob raug kev puas tsuaj los ntawm xob laim, thiab rov qab hloov pauv overvoltage puas tsuaj. Saib yuav ua li cas fais fab transformers tiv thaiv xob laim.
Kev hloov pauv zoo tshaj qhov hluav taws xob thaum txoj kab qis-voltage sab raug ntaus los ntawm xob laim, lub xob laim tam sim no nkag mus rau hauv qhov qis-voltage winding thiab nkag mus rau hauv av los ntawm qhov nruab nrab point grounding device, thiab cov av tam sim no ua rau lub zog poob rau hauv av tsis kam. Qhov kev poob qis no ua rau muaj kev nce siab hauv qhov nruab nrab ntawm qhov muaj peev xwm ntawm sab qis-voltage. Nws superimposes lub overvoltage ntawm qhov qis-voltage winding thiab ua rau muaj kev phom sij rau qhov qis-voltage winding. Nyob rau tib lub sijhawm, qhov hluav taws xob no tau nce mus rau sab siab-voltage raws li qhov hloov pauv hloov pauv los ntawm electromagnetic induction ntawm high- thiab low-voltage windings, thiab superimposed nrog rau theem voltage ntawm high-voltage winding, uas ua rau muaj kev cuam tshuam ntawm lub zog hluav taws xob. txaus ntshai overvoltage nyob rau hauv high-voltage winding. Qhov no tshwm sim hais tias lub low-voltage winding yog raug rau xob laim tawm tsam overvoltage thiab hloov mus rau high-voltage sab los ntawm electromagnetic induction, ua rau lub overvoltage ntawm high-voltage winding yog hu ua zoo transformation overvoltage.
Inverse conversion overvoltage Thaum lub high-voltage sab kab raug ntaus los ntawm xob laim, lub xob laim tam sim no yog tawm mus rau hauv av los ntawm high-voltage sab ntes, thiab cov grounding tam sim no ua ib tug voltage poob rau hauv av kuj. Qhov hluav taws xob poob qis no ua rau ntawm qhov nruab nrab ntawm qhov qis-voltage sab, thiab cov kab hluav taws xob qis sab tawm yog sib npaug rau hauv av los ntawm cov resistor nyob rau lub sijhawm no, yog li feem ntau ntawm qhov hluav taws xob yog siv rau qhov qis-voltage winding. Tom qab electromagnetic induction, qhov no voltage poob nce mus rau high-voltage sab nrog ib tug transformation piv, thiab yog superimposed nyob rau theem voltage ntawm lub hwj chim transformer ntawm high-voltage winding, uas ua rau ib tug overvoltage nyob rau hauv lub high-voltage winding thiab tawg. xwm txheej. Qhov tshwm sim uas sab high-voltage raug ntaus los ntawm xob laim, ua rau sab qis-voltage, thiab hloov mus rau sab high-voltage los ntawm electromagnetic induction, ua rau overvoltage ntawm high-voltage winding, uas yog hu ua inverse transformation overvoltage. .
Kev siv fais fab transformers yuav tsum tsis tsuas yog them sai sai rau kev hloov pauv mus rau pem hauv ntej thiab thim rov qab, tab sis kuj tseem tiv thaiv kev tiv thaiv hluav taws xob ntawm kev faib hluav taws xob.
