Codsiga ASJ Hadhaaga Relay-ga hadda ee Mashruuci Dejinta Generator ee Maldives

1. dulmar mashruuca

Mashruucani wuxuu ku yaalaa Maldives. Ujeedada wareejinta hadda jirta ee hadhaaga ah ee la rakibay waa in la ogaado hadhaaga hadda oo la barbar dhigo qiimaha hadda jira iyo qiimaha saldhiga. Marka qiimaha hadda jira uu dhaafo qiimaha saldhiga, waxa ay soo diri doontaa calaamada damisa makaanikada (si loo sameeyo daaranaha makaanikku jabay ama aaladda acousto-optic alaarmiga waxa ay soo dirtaa alaarmiga). contactor danab hoose, iwm qalab ilaalinta hadda hadhaagii la isku daray, inta badan codsatay in ay ac 50 Hz, danab lagu qiimeeyay 400 v iyo ka hooseeya TT iyo TN wareegga qaybinta nidaamka, loo isticmaalo in dhulka ilaalinta qaladka wareegga korontada, ka hortagga dhaawaca qalabka ay keento cillad dhulka hadda iyo korontada shilalka dabka, sidoo kale waxaa loo isticmaali karaa in si toos ah loola xiriiro qofka helo khatarta shoogga koronto, sidaas darteed waxaa si ballaaran loo isticmaalaa sahayda korantada hoose iyo nidaamka qaybinta.

2. Isticmaalka ugu muhiimsan ee gudbinta hadda jirta

2.1 Ilaalinta Shubka Korontada ee Xiriirka Dadban

Cabbirka xiriirka aan tooska ahayn ee ilaalinta shoogga korontadu waa in si toos ah loo gooyo korontada. GB. Qalabka. Marka dhaawaca dahaarka wareegga uu keeno cilladda dhulka. Sida laga soo xigtay cilmi-baarista, qiimaha nabdoon ee danab xiriirku waa 50V. Badbaadada shakhsi ahaaneed, marka dahaarka ay ku dhacdo qayb kasta oo ka mid ah qalabka korantada, marka korantada xiriirku dhaafto 50V, waxaa lagama maarmaan ah in si toos ah loo gooyo qaybta cilladda korontada ee wakhtiga la cayimay. Qalabka ilaalinta ee hadda ka badan waxa xaddidaya wareegga korantada iyo qalabka iyo qiimihiisu waxqabad, oo si toos ah uma jari karo korontada. Aaladda ilaalinta hadhaaga ah ee hadda jirta ma saamayso culayska hadda socda waxaana loo isticmaali karaa iyadoo lala kaashanayo aaladda ka-hortagga xad-dhaafka ah ee ilaalinta shoogga korantada ee aan tooska ahayn.

2.2 Ilaalinta khaladka dhulka

Grounding waa xidhiidhka ka dhexeeya kirishbooyada nool iyo dhulka, qolof bir ah oo dhulka ah ama qayb ku xiran dhulka. Guuldarradeedu waxa ay u horseedi kartaa khasaare nafeed oo koronto ah oo shakhsi ah iyo burbur qalabeed, waxana laga yaabaa inay keento dab koronto xaalado halis ah. Ilaalinta khaladka dhulka ee loo isticmaalo in lagu ilaaliyo aaladda ilaalinta hadda jirta. Marka cilada dhulka ee hadda uu ka weyn yahay qiimaha go'an ee qalabka ilaalinta hadda ka badan, wareegga cilladda waxaa gooyaa qalabka ilaalinta ee hadda taagan.

Nidaamka TT, xariiqda leh khad qaybinta hadda la qiimeeyay oo dheer, cilada dhulka ee kirishbooyada nool, cilad dhulka birta ah oo aan badbaado lahayn iyo cilad dhulka arc ee nidaamka TN ayaa dhici karta in cilada dhulka ee hadda jirta ay ka yar tahay goobta hadda ee ilaalinta xad-dhaafka ah. wax qabad, iyo qalabka ilaalinta ee hadda ka badan ma dhaqmo. Qalabka ilaalinta hadhaaga ah ee hadda jira, ama wareegtada wareegga leh ee leh ilaalinta cilada dhulka, ayaa si kalsooni leh u fulin karta ilaalinta cilladda dhulka.

2.3 Ilaalinta dabka korantada

Dabka korantada waxaa badanaa sababa koronto gaaban, oo ay ku jiraan wareegga gaaban ee birta iyo wareegga gaaban ee arc. Midka hore waa wareeg gaaban oo u dhexeeya kirishbooyada nool (sida inta u dhaxaysa wejiyada, inta u dhaxaysa wejiyada iyo khadadka N). Cilladda hadda jirta waxaa lagu xisaabiyaa kilo ampere. Heerkulka sare waa sahlan tahay inuu keeno oksaydhaynta dahaarka iyo gubasho kedis ah.

Inkasta oo khatarta dabku ay aad u weyn tahay, waxaa lagu ilaalin karaa fiyuusyada wareegga wareegga iyo fiyuusyada ilaalinta wareegga gaaban, korontadu waxay goysaa ficil degdeg ah oo wareeg ah si looga fogaado dabka. Midka dambe waa kaari nool oo gaaban oo wareeg ah oo dhulka ah, inta badan arc sida waddada, inkasta oo ciladda hadda jirta ay yar tahay, laakiin dhinaca kale, arcku wuxuu soconayaa waqti dheer, heerkulka maxalliga ah ayaa sarreeya, way fududahay in la shido. walxaha guban ee ku hareeraysan oo keena dab. Sidaa darteed, khatarta dabka ee ay keento wareegga gaaban ee arc ayaa aad uga weyn kan wareegga gaaban ee birta ah. Xakamaynta wareegga leh ee hadhaaga ilaalinta ficilka hadda jirta waxay gooyn kartaa wareegga taageerada iyada oo aan la shaqeynin qalabka ilaalinta ee dheeraadka ah si looga hortago dabka korantada ee uu keeno wareegga gaaban ee arc.
