Ko te kōwhiringa tika o te ara iahiko takahi

E mea pinepine, mai te wa ki te whakakapi i te waea hiko, me te me kia whakakapi ara iahiko takahi i roto i te te hanga hanganga hou ranei. A, no te toro i te electricians toa tata tonu kite tatou e 99% o te whānuitanga o te mania-tuatea ake whakaaro ki hīrau ānau C. Fakatatau, kia mea he e ko te putanga taea, me te tika anake tenei. Kei te whakatapua ana tēnei tuhinga ki te arotake o tetahi o te nui ngā āhuatanga o te mania-kaiwahi - hīrau ānau.

Ko nga hononga hīrau o taiawhio-tuatea ngā o rua nga wahi:

• triggering tiaki kikī (waiariki): te, te poto te wa atu teitei te nāianei;
• hīrau i runga i iahiko poto (tuku hiko) ki te nui te nāianei te wāhi i whakaritea o te wa haerenga tiaki he iti iho i te 10 hākonamano.

Hoki ngā poto-iahiko i runga 20 nga wa te nāianei, ngā āhuatanga wā-nāianei tauanga (atu ānau) e kore e whakarato whakaaturanga pū rawaka.

Mono nui ngā poto-iahiko āhuatanga e ānau rohe o nāianei (puhake nāianei, me te pūngao). Ko te wa katoa i tangohia atu e taea e āhua rite ki te rima nga wa te uara o te ōwehenga (I2t) / (ahau) 2.

Taki te selectivity i waenganui i rua iahiko-tuatea

Na roto i te superimposing ara iahiko takahi ānau ki te ānau whakarunga takahi iahiko e taea taki mēnā tenei huinga o ngā pūrere tīpakongia i te take o te kikī (selectivity mō ngā uara katoa o nāianei, tae noa ki te pana hiko pai setpoint). He whaitake taua whakaū ina kua he wāhi huinga whakarite tetahi o nga tuatea iahiko e rua; hoki ngā pūrere ki ngā tautuhinga tamau, e taea te kitea i tika tenei kōrero i roto i te selectivity tepu. Hei whakamātau i te selectivity ki poto-iahiko ko reira e tika ana ki te whakarite i te āhuatanga pūngao o te whakaaro e rua.

Tauira: rite hīrau ānau i te ahua, te ara iahiko takahi iC60 Schneider Electric Acti 9 (ānau C, he nāianei iti o 20 A) mono nāianei 100 A (i.e. 5-korukoru te I nāianei tauanga) o:
• i te iti rawa 2 hēkona;
• he mōrahi o 7 hēkona.

āhuatanga o nāianei Wā

Te tohu i te wa me ouschestvlyatsya āhuatanga o nāianei rite ki te momo tiaki te pūnaha rite mo te tiaki o te whakaritenga pūnaha hiko e rerekē tonu. I roto i tenei hononga, i roto i te tauine taputapu e 6 ānau rerekē.

ānau B

Decoupling: 3 ki te 5 I roto i te (rated nāianei) IEC 60898
Ko te tikanga te nuinga mo te tiaki o generators, me i nei i reira he kore nāianei tihi inrush

ānau C

Decoupling: 5 ki te 10 I roto i te (rated nāianei) IEC 60898
Ko te tikanga ki te tiaki i te waea i roto i te take o te whakaaro whānui

Ānau D me K

Decoupling: 10 ki te 14 I roto i te (rated nāianei) IEC 60947,2
Ko te tikanga te reira ki te tiaki i takatakanga ki te nui o nāianei tīmatanga, me ki te tiaki i transformers imennoo me motors.

Z ānau

Decoupling: i 2.4 ki te 3.6 I roto i (rated nāianei) IEC 60898
Hangaia matua mo te tiaki o te taputapu hiko.

ānau MA

Decoupling: 12 I roto i te (rated nāianei) IEC 60898
Hangaia ki te tiaki i nga whakaaro triggering anake rite i konei kahore he pūrere hīrau waiariki.
