Kev tiv thaiv kev ntsuas tam sim no Transformer hlawv
Feb 17, 2023| 1 Ua rau tam sim no transformer burnout
(1) Qhov thib ob qhib Circuit Court ntawm tam sim no transformer generates high voltage thiab burns tawm tam sim no transformer.
(2) Lub neej kev pab cuam ntawm lub tam sim no transformer ntev dhau lawm, lub rwb thaiv tsev yog aging, lub zos tawg los yog paug tshwm sim, thiab overvoltage yog generated, uas ua rau tam sim no transformer kom sov thiab hlawv tawm.
(3) Kev sib cuag ntawm qhov tam sim no transformer ib zaug txuas nrog txhuas kab yog oxidized hnyav heev, kev tiv thaiv kev tiv thaiv yog loj heev, thiab lub tshav kub ua rau lub transformer tam sim no hlawv.
(4) Tus neeg siv yog overloaded rau lub sij hawm ntev, ua rau tam sim no transformer kom sov thiab hlawv tawm.
2 Muaj teeb meem nrog lub Circuit Court breaker thiab xaim ntawm cov neeg siv tshwj xeeb transformer
(1) Feem ntau, 10kV nqus Circuit Court breakers thiab SF6 Circuit Court breakers yog nruab nrog overcurrent thiab overload tiv thaiv. Thaum muaj ib theem-rau-theem luv luv Circuit Court los yog overload, lub Circuit Court breaker tuaj yeem mus kom raug, thiab overvoltage raug txiav tawm los ntawm cov ntsia hlau zinc oxide ntes. Tam sim no transformers rau high-voltage metering ntawm cov neeg siv khoom siv hluav taws xob nyob rau hauv peb txoj cai yog tag nrho nruab nrab ntawm qhov kev hloov pauv thiab lub Circuit Court breaker, yog li ntawd ib zaug lub transformer tam sim no tsis ua hauj lwm, tsis yog lub Circuit Court breaker los yog xob laim ntes tau tshem tawm qhov txhaum, thiab lub Circuit Court breaker nyob rau theem siab yuav tawm mus thiab tshem tawm nws. txhaum, yog li nthuav dav ntawm lub zog hluav taws xob, thiab tib lub sijhawm, tam sim no transformer yuav raug hlawv vim qhov kev ncua ntawm kev tshem tawm qhov txhaum.
(2) Thaum cov av ib-theem tshwm sim ntawm cov neeg siv sab, vim hais tias lub Circuit Court breaker tsis tawm mus, nws yog ib qho tsim nyog yuav tsum rub cov ceg ntoo tawm ntawm ib qho kab ib los ntawm ib qho los nrhiav qhov chaw hauv av, uas tseem yuav ua rau cov pej xeem kab yuav tsum tau deactivated thiab ua kom muaj zog ntawm hluav taws xob.
(3) Lub rwb thaiv tsev ntawm lub surge arrester ntawm tus neeg siv sab yog laus thiab tsis tuaj yeem tiv thaiv overvoltage zoo.
3 coj tawm tsam
(1) Txhim kho lub ntsuas hluav taws xob tiv thaiv hluav taws xob tiv thaiv cov ceg tsis ua haujlwm los ntawm kev cuam tshuam rau tag nrho cov khoom siv hluav taws xob, tshwj xeeb tshaj yog kom ntseeg tau tias cov ceg hluav taws xob hluav taws xob tuaj yeem tuaj yeem ntseeg tau thaum lub hwj chim sab yog ib theem hauv av.
(2) Txuas lub metering tam sim no transformer mus rau sab nraum qab ntawm Circuit Court breaker kom paub meej tias lub Circuit Court breaker thiab xob laim ntes ua haujlwm kom raug tshem tawm qhov txhaum thaum lub ntsuas hluav taws xob tam sim no ua tsis tiav.
(3) Txhim kho qhov ntsuas hluav taws xob hluav taws xob siab ntawm cov neeg siv hluav taws xob ntsuas hluav taws xob tam sim no thiab surge arresters (tsis pub ntau tshaj 4 xyoo raws li kev cai), kev tshawb pom ntxov ntawm cov hluav taws xob hluav taws xob hluav taws xob ntawm cov ntsuas tam sim no transformers thiab surge arresters, thiab raws sij hawm. hloov kom tsis txhob muaj hluav taws xob tawm los ntawm burnout ntawm metering tam sim no transformers.
(4) Tsis tu ncua ntxuav tus neeg siv cov cuab yeej tseem ceeb kom txo tau cov pa phem flashover thiab tsis txhob cuam tshuam cov rwb thaiv tsev.
