Whakakā rocker - āhuatanga hoahoa, momo

Circuit kaiwahi - he motuhake papahiko. Kei te whakamahia te reira no te whakawhiti i te ara iahiko hiko mō te whakahaere hiko. mahi e te actuator ā-peheé pūnaha. Hei tauira, i roto i te tirohanga hanga o te pūnaha hiko ranei kahore pūrere o tenei ahua e kore e mahi. Changeover whakakā i roto i te whānui ko tetahi o nga whakarerekētanga māmā o te whakakā o te rōpū.

Taupānga me te whakarōpū

Ki te kōrero tatou e pā ana ki te maha o ngā hoapā, ka taea e enei whakaaro e:

1) Maha-pou.

2) e toru-pou.

3) pourua.

4) Single-pou.

I tua atu, e taea te tutaki changeover whakawhiti ki te hua lateral pokapū ranei.

Hei hāngai tenei pūrere pinepine whakamahi pouaka tiaki motuhake. I te taha ki waho i te hua mana, ko te putanga.

Ka taea te ngāwari te whakamahi ēnei whakaaro i roto i te tāuta ahumahi kore anake, engari ano hoki mō ngā take kāinga. He ao Tetahi pana changeover.

He aha kia titiro ahau mo ina hoko?

I roto i te tikanga ki te hanga i te whiriwhiri tika, he mea e tika ana i te omuaraa ki te whakatau he aha e kia whakamahia rite tenei pana. I muri i taua kua taea te neke koe i runga i ki ētahi atu kōwhiringa. I tua atu, he mea nui ki te mohio he aha te mana o taputapu hiko, ngā i roto i tetahi ki tetahi whatunga ranei.

Tohunga whakahua i te tawhā torutoru e kia utu koutou whakarongo, te toro toa motuhake. Tenei tūranga whakahaere, whakaturia wa whakahaere kore, whakanohonga kāwai rite ki GOST me mahi makariri, ngaohiko tauanga, tauanga whawhati nāianei, me te maha o amo.

Me pēhea te ki te kīa te tohu?

Ki te whakaatu i te mōkihi e rua tau, e pā ana te tuarua ki te nāianei tauanga, me te tuatahi - te maha o amo. Ki te te whakakā changeover Kei te tapa te b reta, te tikanga reira e kei te whakamahi koe i te hua taha. C - ko te ti'araa mo te pokapū. A, no te e nga reta e rua, me te tuarua o ratou titau, te auraa te waea mua. I te pae hopea, n me te p - pana, me te whakawhiti aua.

He bit e pā ana ki te hoahoa

pūnaha momo mata Whakapā - he wāhanga whakahauanga o tetahi whakakā o tenei momo. I tua atu, i reira e tonu taipitopito i roto i te puka o ngā topenga puna. E ngā maripi Metal i roto ratou, ka katia te pūnaha te. Nā ki tenei changeover whakawhiti whakamahi e kore e whatiia whakapā.

mōhiohio atu

Te ngaro ranei aroaro dugogasilnyh ruma - hanganga pea mō te pūrere ki te hua actuator hapai i te taha ranei. Ki te faatumuhia te reira, te kāmera motuhake e ngaro tonu. Ko reira te mea he hoapā Purangi arrester. Ko te kupu, ka momotuhia taputapu, e kore e whakawhirinaki ai i runga i te tere ki i tītaka te hua. Ki te he nui atu i te 200 amperes te nāianei pūrere, hei tauira, i reira te mea he 400A changeover whakakā, ka whakarei i te pūrere e ki puna maitai.

I tua atu, kia honoa te tauira ki fuses, e whakarato tiaki atu. Hei tauira, ka taea ki te whakatau i te whakakā changeover hanganga 250A te taua.
