Te tirohanga tuatahi: He aha te MCB

MCB, e mōhiotia ana hoki kopakaru ara iahiko iti, he itipakaru hikohe mahi nui tēnei i roto i ngā pūnaha hiko. Kāore i rite ki ngā fiusi tuku iho, ka taea te whakamahi anō i ngā MCB, ka whakarato i te tiakitanga pai ake i ngā hapa hiko e puta mai ana i ngā taumahatanga ara iahiko, i ngā ara iahiko poto rānei. Ka whakarite ngā kaiwawao ara iahiko iti i te haumaru me te pono o ngā taputapu hiko mā te whakahaere ā-ringa, aunoa rānei i te whakawhiti ara iahiko.

Tirohanga tuarua: Te mahi a te MCB

Ko te kaupapa mahi a te MCB e ahu mai ana i te tikanga whakaroa aukume wera. Ina rere te iahiko i roto i te MCB, ka puta he papa aukume. Mena ka tae te iahiko ki te uara kua whakaritea, ka motu aunoa te MCB ka tapahia te ara iahiko. Hei tāpiri, ka kitea e ngā huānga wera o te MCB ngā huringa pāmahana. Mena ka nui ake te pāmahana i te uara kua whakaritea, ka motu anō te MCB, ka ārai i te ara iahiko kei wera rawa.

Tirohanga Tuatoru: Ngā Momo o ngā Waka Whakamutu Ara Iahiko Iti

Kei te wātea ngā MCB i roto i ngā tauira maha i runga i tō rātou au hiko kua whakatauria, pērā i te 6A, 32A, 64A, me ētahi atu. Ka whakarōpūtia hoki i runga i te maha o ngā pou kei a rātou, mai i te unipolar, bipolar, ki ngā whirihoranga pou-toru.

Nā tōna hoahoa kiato, he pai mō ngā whakaurunga hiko hou. Tuarua, ka taea te whakamahi anō i ngā microcircuit breakers i ngā wā maha, ā, he iti ake te utu me te whai hua. Kāore i rite ki ngā fiusi, me whakakapi i muri i ia pakaru, ka taea te tautuhi anō i ngā MCB, ka penapena i te wā me ngā rauemi.
