Umgaqo-siseko woYilo kunye noMzobo woNxibelelwano lwe-Dual Power Automatic Transfer Switch ATSE

Ukhetho lweizixhobo zokutshintsha ezizenzekelayo (ATSE)kufuneka ihlangabezane nezi mfuno zilandelayo:

1. Xa usebenzisaPC-iklasi utshintshelo oluzenzekelayo izixhobo zombane, kufuneka ikwazi ukumelana nokulindelweyo kwi-short-circuit current ye-circuit, kunye ne-rated current yeATSEkufuneka ingabi ngaphantsi kwe-125% yombane wokubala wesekethe;
2. Xa iklasiCB ATSEisetyenziselwa ukunika amandla kumthwalo womlilo,ATSEebandakanya i-breaker circuit kunye nokukhusela isiphaluka esifutshane kuphela siya kusetyenziswa.Ukukhethwa kwayo kokukhusela kufuneka kuhambelane nezixhobo zokukhusela eziphezulu kunye nezantsi;
3. I-ATSE ekhethiweyo kufuneka ibe nomsebenzi wokulondoloza nokwahlula;NiniUmzimba we-ATSEayinalo umsebenzi wokulondoloza wedwa, amanyathelo okuzihlukanisa kufuneka athathwe kuyilo.
4. Ixesha lokutshintsha kweATSEkufuneka kulungelelaniswa kunye nexesha lokukhusela i-relay yonikezelo lwamandla kunye nenkqubo yokusabalalisa, kunye nokunqunyulwa okuqhubekayo kufuneka kugwenywe;
5. NiniATSE iimpahlaamandla kumthwalo omkhulu wemoto, ixesha lokutshintsha kufuneka lilungiswe ngokufanelekileyo ukuze kuqinisekiswe ukutshintshwa okukhuselekileyo nokuthembekileyo ngexesha lenkqubo yokutshintsha.

YEQ3 CB Class ATSE

Amanqaku aphambili okuqonda kunye nokuphunyezwa ngolu hlobo lulandelayo: I-ATSE isetyenziselwa ukuguqulwa okuzenzekelayo phakathi kokunikezelwa kwamandla amabini, kwaye ukuthembeka kokunikezelwa kwamandla kwimithwalo ebalulekileyo kubalulekile.Imveliso yahlulwe ibeIklasi yePC(eyakhiwe zizitshixo zomthwalo) kunyeIklasi ye-CB(eyakhiwe ngabaphuli beesekethe), kwaye uphawu lwayo lunomsebenzi "wokuzifaka kunye nokuziphendulela".

Ixesha lokuguqulwa kwe-ATSE lixhomekeke kwisakhiwo sayo.Ixesha loguqulo lweIklasi yePCngokuqhelekileyo yi-100ms, kwaye leyo yeklasi ye-CB ngokubanzi ngu-1-3S.Kukhetho lwePC iklasi transfer oluzenzekelayo switsha, umthamo wayo olinganisiweyo akufanele ube ngaphantsi kwe-125% ye-calculation calculation current, ukwenzela ukuba kuqinisekiswe ukuba ukutshintshwa kokutshintshwa ngokuzenzekelayo kunomda othile.Ngenxa yePC iklasi ATSEngokwayo ayinayo umsebenzi wokukhusela ogqithisiweyo, ngoko ke abafowunelwa bayo kufuneka bakwazi ukujamelana nokulindelweyo kwi-short-circuit current yesekethe, ukuqinisekisa ukuba uqhagamshelwano aludityaniswanga phambi kokuba i-ATSE superior short-circuit breaker inqumle impazamo, kwaye ingaba itshintshe ngokuchanekileyo.

Xa iklasiCB ATSEzisetyenziselwa ukubonelela amandla kwimithwalo yokulwa nomlilo, i-atses equkethe kuphela i-breaker circuit breaker kunye nokukhusela i-circuit breaker kufuneka isetyenziswe ukukhusela ukusilela kwamandla ezixhobo zokulwa nomlilo ngenxa yokukhubeka komthwalo ongaphezulu.Ukukhuselwa kwayo okukhethiweyo kufuneka kuhambelane nezixhobo zokukhusela eziphezulu kunye nezisezantsi ukukhusela uluhlu olukhulu lokungaphumeleli kwamandla okubangelwa ukukhubeka.

umzobo wocingo lwe-ATSE

NiniATSEisetyenziselwa ukuguqulwa kwamandla amabini, ngenxa yokhuseleko, kuyafuneka ukuba ube nomsebenzi wokuhlala wedwa.Apha, ukubekelwa bucala kwesondlo kubhekiselele kulondolozo lodwa lwelophu yokuhambisa ye-ATSE.Xa uyila unikezelo lwamandla kunye nenkqubo yokuhambisa inomsebenzi wokuvala ngokuzenzekelayo, okanye nangona kungekho msebenzi wokuvala ngokuzenzekelayo kodwa kwinqanaba eliphezulu le-substation ephezulu inomsebenzi, sebenza amandla ngokukhawuleza alahlekelwa amandla, i-ATSE ayifanele iphoswe kwicala lokubonelela ngamandla ngoko nangoko, kufuneka dodge oluzenzekelayo ukulibaziseka ukuvala ixesha, ukuphepha ukutshintshela nje kwicala lonikezelo lwamandla olindileyo, kwaye ukusuka entsonkothileyo ukuya kumandla okusebenza, olu hlobo lokutshintsha okuqhubekayo luyingozi ngakumbi.

Ngenxa yokusabela okuphezulu kwe-inductive yomthwalo omkhulu wemoto, i-arc inkulu kakhulu xa ivula kwaye ivala.Ngokukodwa xa umbane olindileyo uqhagamshelwe kumbane osebenzayo, zombini izixhobo zombane zihlawuliswa ngexesha elinye.Ukuba akukho kulibaziseka kwinkqubo yokudluliselwa, kukho ingozi ye-arc isiphaluka esifutshane.Ukuba ukulibaziseka kwe-50 ~ 100ms yongezwa kwinkqubo yokutshintsha ukuphepha ixesha xa ukukhanya kwe-arc kuveliswa ngexesha elifanayo, ukutshintsha okuthembekileyo kunokuqinisekiswa.
