LXK Na Cikin Gida Zero Sequence Instrument na Yanzu Masu Canzawa Don Rarraba Wutar Lantarki

Tsarin sifili na yanzu na yanzu shine nau'i na musamman na na'ura mai canzawa wanda akafi amfani dashi don gano jerin sifilin halin yanzu a tsarin wutar lantarki. Sifili na halin yanzu yana nufin halin yanzu wanda jimlar igiyoyin igiyoyi uku ba daidai suke da sifili ba lokacin da nauyin da ba shi da ma'auni na matakai uku ko kuskuren ƙasa-lokaci ɗaya ya faru. Juyin sifili na yanzu na'urorin wuta suna da mahimmancin ƙimar aikace-aikacen a cikin tsarin wutar lantarki, saboda suna iya ganowa da kare amintaccen tsarin wutar lantarki.

1. Sifili-sequence na yanzu tasfofi an tsara su musamman don auna ragowar halin yanzu a cikin tsarin wutar lantarki, wanda ke da mahimmanci don gano kuskuren ƙasa da tabbatar da amincin kayan lantarki. .

2. waɗannan LXJ Type Zero-sequence transformers suna da babban matakin daidaito, yana sa su dogara ga ainihin ma'auni na yanzu.

3. LXJ jerin sifili-jeri na yanzu na'ura mai ba da hanya tsakanin hanyoyin sadarwa ne m a cikin girman, sa su sauki shigar da dace da daban-daban aikace-aikace.

4. Sifili-jeri na yanzu tashoshi suna da fadi da kewayon mita, kyale su yadda ya kamata auna igiyoyin a cikin ƙananan da kuma high mita tsarin.

5. Wadannan sifili-sequents na yanzu taswirar suna da matukar damuwa ga ƙananan igiyoyin ruwa, yana sa su dace don gano ko da ƙananan rashin daidaituwa a cikin tsarin lantarki. Gabaɗaya, sifili-jeri na yanzu na'urorin wuta sune mahimman abubuwa a cikin tsarin wutar lantarki don auna daidai ragowar igiyoyin ruwa da tabbatar da cikakken aminci da ingancin hanyar sadarwar lantarki.

1. Rated secondary current: 5A ko 1A

2. Ƙarfin wutar lantarki: cosφ=0.8(lag)

3. Ƙididdigar mitar: 50Hz ko 60Hz

4. Ƙididdigar farko na halin yanzu, ƙimar fitarwa, da ingantaccen matakin duba tebur 1

5. Insulating dukiya: na farko winding zuwa sakandare winding da ƙasa, da kuma sakandare winding zuwa ƙasa iya ɗaukar ikon mitar jure ƙarfin lantarki 3kV for 1min.
