Ib qho - Theem Leakage Protector tuaj yeem txuas rau peb - ​​Theem Plaub - Hlau Circuit Court

Ib-theemleakage tswj(ua los ntawmminiature-circuit-breaker) tsis tuaj yeem txuas nrog peb-theem plaub-hlau Circuit Court.Cov txheej txheem tau tshwj xeeb,Ib-theem xau hloov MCBNyob rau hauv cov khoom siv tu hauv lub xoom-ib theem tam sim no transformer nrhiav pom yog ib theem kab (pem hauv ntej) thiab ib txoj kab null ntawm qhov seem tam sim no vector, ib zaug cov xau tam sim no tshaj 30mA, los ntawm lub davhlau ya nyob twg los tua cov cuab yeej tripping, yuam lub sab hauv tripping kev ua haujlwm, kom ua tiav lub luag haujlwm tu.

Cov kab kos duab ntawm2P hloov pauvraws li qhia hauv qab no:

Ib leeg-theem leakage tiv thaiv tuaj yeem txuas nrog peb-theem plaub-hlau Circuit Court

Ib-theem hluav taws xob hloov pauvmuaj theem kab thiab null kab tswj, muaj cais theem kab tswj.Txawm hais tias muaj ib txoj kab null nyob rau hauv peb-theem plaub-xaim fais fab mov, nws tuaj yeem tsim los ntawm 220V voltage nrog peb theem kab arbitrarily, tab sis nws tsis tuaj yeem tswj hwm ob theem kab.

Daim duab kab hluav taws xob ntawm peb-theem plaub-xaim xaim hloov pauv tau pom hauv daim duab saum toj no.

Nws yog tsim nyog sau cia tias lubpeb-theem leakage swch muab faib ua 3P thiab 3P + N, lubleakage hloovntawm cov qauv no yog me ntsis kim dua li qhov hloov pauv ib-theem to.

3P + N fais fab mov input hlau tsuas yog yuav tsum paub tias cov hlau nruab nrab txuas nrog N, thiab lwm yam L1, L2, L3 tuaj yeem txuas nrog lub davhlau ya nyob twg.

3 p + N leakage ntawm kev saib xyuas ntawm N kab ncaj nraim (txawm hais tias yog cais nyob rau hauv lub xeev channel), kev sib txuas yuav tsum ua ntej ntawm sab laug, txoj kab null los ntawm kab hauv N, yog N xaim txhaum rau pem hauv ntej tsis muaj peev xwm tswj tau qhov tripping circuit tas li muaj hluav taws xob tu.
