Single - Phase Leakage Protector Atha Kulumikizidwa ku Atatu - Gawo Lachinayi - Wire Circuit

Gawo limodzikutayikira wosamalira(yopangidwa ndikakang'ono-circuit-breaker)singathe kulumikizidwa ku gawo la magawo atatu a waya.Tekinolojeyi ndi yapadera,single-phase leakage switch MCBmu chipangizo chokonzera kutayikira mkati mwa zero-sequence current transformer kuzindikira ndi mzere wagawo (kutsogolo) ndi mzere wopanda kanthu wa vekitala yotsalayo, pamene kutayikira kwapano kupitirira 30mA, kupyolera mu terminal kuti agwiritse ntchito chipangizo chodumpha, kukakamiza kulowa mkati. dongosolo zochita, kukwaniritsa ntchito yokonza.

Chithunzi cha wiring cha2P kusintha kusinthamonga momwe zilili pansipa:

Single - gawo kutayikira mtetezi akhoza olumikizidwa kwa atatu - gawo 4 - waya dera

Single-phase leakage switchali ndi gawo la mzere ndi mzere wa null line control, pali zosiyana zowongolera mzere.Ngakhale pali mzere wopanda pake mu magawo atatu amagetsi amagetsi anayi, amatha kupangidwa ndi voteji ya 220V yokhala ndi mizere itatu mosasamala, koma sangathe kuwongolera mizere ina iwiri.

Chojambula cha mawaya a magawo atatu a mawaya akutayikira mawaya akuwonetsedwa pachithunzi pamwambapa.

Ndikoyenera kudziwa kutimagawo atatu leakage switchh agawidwa mu 3P ndi 3P+N, ndileakage switchza kapangidwe kameneka ndizokwera mtengo pang'ono kuposa kusintha kwa gawo limodzi lotayirira.

3P + N mawaya opangira magetsi amangofunika kudziwa kuti waya wosalowerera ndale walumikizidwa ndi N, ndi zina L1, L2, L3 zitha kulumikizidwa ndi ma waya.

3 p + N kutayikira kwa kukonza kwa mzere wa N ndikowongoka (ziribe kanthu kaya padera panjira), kulumikizana kuyenera kukhala kutsogolo kumanzere, mzere wopanda mzere ndi mzere mu N, ngati waya wa N wolakwika kutsogolo. sikutha kusunga mayendedwe oyenda mosalekeza kukhala ndi kukonza magetsi.
