Dimmer: kaupapa, me te taputapu. Ngā Whakakā ki dimmers

E whakamahia ngā mana Motuhake ki te whakatika i te wherikotanga o rama aano atu. e karangatia hoki enei whakaaro dimmers. tīariari ratou i roto i putanga rerekē, me, te mea e tika ana, i roto i te taonga e taea te whiriwhiri tonu koe i te tauira e tika ana. Fele, whakakapi ratou he takahi taiawhio i roto i te rama aano atu. Ko te whakarerekētanga māmā ngā te pūmana hurihuri ki te pene. A, no te toenetanga te luminance wāhanga atu rerekētanga i roto i te kohi hiko.

Ki te mahara koe i nga ra tawhito, e kore te te mana mō te whakatikatika wherikotanga whakamahia. Engari, tāuta dimmers motuhake. Ki te to ratou awhina, hoki e taea te whakahaere e koe rama antibody. I roto i te whānui, me te mau ohipa tāia ki te pai ratou, engari i ratou kotahi ngoikoretanga. Kei te hono te reira ki te kai o te hiko. Ka rite ki whakahuatia i mua, noho tauwehe hou iti hiko, ki te kore e whakamahia i te kaha tonu. I roto i te take o te parenga e kore e tono i taua ture. pau te mana iti hiko me te i te mōrahi. Taikaha i roto i tenei take tahuri ki te wera.

Aronui regulator tikanga

Simple iahiko dimmer tā te whakamahi o te momo potentiometer rārangi, me te rua o transistors ki te kaha iti. Hei te pehi i ngā pūnga auau tiketike e whakamahia i roto i te pūnaha. Me momo ferrite anake nga otaota i roto i te whakaaro o tenei momo. Tonu i mua i te whakaturia te kāpeka ki te ngōhiko thyristor Shockley.

Me pēhea te ki te tahuri te waea ki te rama?

Ki te rama tepu ki dimmer mahi tikanga, tirohia te ngaohiko puta noa i te Semiconductor. Ka taea te mahi i tēnei te whakamahi i te pourewa tikanga. Next, tirohia te umanga poari. Ki te whakaturia ana odnokalnogo momo, mahi katoa tino noa. Ko te Semiconductors putanga tūhono nui ki te putanga tatau, e he wehenga tawhiti tōraro. I roto i tenei take me waiho te ātete mōrahi 3 ohms. Hei whakamātau i te pūrere, me huri koe i te kaiwhakahaere, me te mataara i te wa ano mo te wherikotanga o rama aano atu.

Tāuta i te pātene pana i roto i te rama

Hei whakahaere i te wherikotanga o rama aano mahi tika, he mea nui ki te mōhio ki te poari whakahaere pūrere. Next, Me koe ki te hono i tō hoapā katoa. Ki te whakamahia te ara iahiko kei te he maha-hongere, tirohia te ngaohiko ki runga reira te hei whakamatau. Pūhui tika hoapā kawea e brazing. He mea nui i kore e te wa taua i roto i te mahi kino ia pūparenga. I tua atu, e hiahia ana koe ki te tango i te tiaki o te mātao waea. I mua i tahuri i runga i te kaiwhakahaere e hiahia ana koe ki te tirohia e haumaru hononga katoa. I muri i te supply mana he tika ki te ngana ki te huri i te wherikotanga mā te pēhi i te pātene.

mana High wherikotanga

rama te-ngaohiko tiketike dimmer, rite ki te tikanga, e taea te kitea i roto i te whare. E whakamahia He rama aano tino kaha, a kia taea ki te tu atu pikaunga taimaha te pūrere. Triacs mo tenei whakaaro, tiketike-ngaohiko (tohua ki KU202) tono. E whakamahia, Heoi, kua whakatakotoria ona transistors pourua nga whakarerekētanga mua ano hoki.

piriti ngōhiko soldered tata nga thyristors me tika mō te tuku tohu nohopuku. te p Zener maha taea te kitea D814 tohua. Ko ratou i roto i te toa, ko te tino utu, me tenei kia tangohia ki pūkete. parenga tāupe i roto i te pūnaha e taea ki te tu atu rohe ngaohiko o 60 ohms. I tenei wa, tauta ritenga tikanga ki 5 anake ohms.

Tauira ki te parenga pū

Dimmer ki parenga o tenei momo te hangaia mo te aano atu te mana toharite. te p Zener i roto i tenei take, he onge te 12 V parenga Tāupe tauwehe. Ka taea te whakamahi akatuke'anga auau iti. Hei whakanui i kawe ia tau whakarea i roto i tenei take ko reira taea mā te whakapiki i te maha o ngā pūnga. Hoki triac Me whakanohoia ratou i roto i takirua. I roto i tenei take, ka waiho iti nga parekura wera. Ko maha whatunga resistance Negative he raruraru nui. Kikī te mutunga arata'i ki wehenga o te ngōhiko zener. pūnga iahiko -hiko ki iti-auau haruru fekuki rawa pai. Ko te mea matua ki tenei - e kore e hoatu e ngaohiko tiketike koi ki te rama.

Ko te ara iahiko regulator ki parenga vysokomegaomnymi

Ka taea te whakamahi mana wherikotanga o tenei momo ki te whakahaere momo rerekē o rama. Kaupapa Kei roto te reira vysokomegaomnye parenga AC, me te zener tikanga. whakaturia Thyristor i roto i tenei take e muri ki te condenser. Hei whakaiti maha whakamahi i te tohunga auau rohe Fuse momo. E taea ki te tu atu ki te kawenga o 4 A. I tenei auau rohe o te putanga ka waiho he mōrahi o te 50 Hz ratou. Triacs whakaaro whānui tāuru ngaohiko e taea te tu i te 15 V.

He huri ki te tauwehe FET

Ki te whakakā dimmer runga FET āhuatanga e korero pai. Poto-iahiko i roto i te pūnaha puta rawa uaua, a tino ko reira he painga. I tua atu, tēnā mōhio e taea te whakamahi i te regulator Zener anake ki KU202 tohu. I roto i tenei take, he nehenehe o mahi ki parenga auau iti ratou, ka akakoromaki i raweketia pai. Triacs i roto i iahiko kei muri i te pūparenga. takoto te ātete whāiti i roto i te pūnaha te ki kia tonu i 4 ohms. Ko te ngaohiko i te parenga tāuru mau āhua 18 V. rohe auau, i roto i te tahuri, e kore e nui ake 14 Hz.

Regulator ki trimmer

Dimmer ki trimmer pūnga taea te pai te whakamahi ki te whakatika i te mana o rama antibody. Me whakanohoia He huri i roto i tenei take i muri i te piriti ngōhiko. te p Zener i roto i te ara iahiko e hiahiatia ana mo te raweketia pehanga. Kei te nuinga o te wā tonu parenga momo tāupe te te parenga ia whāiti i 6 ohms.

A, no te tenei thyristors e whakamahia anake ki te mau tonu i te ngaohiko i te taumata tika. He onge Triacs roto ano nehenehe o haere nāianei ki te taumata o e pā ana ki 4 momo Fuse A. pūmana. Ko te raruraru ki taua whakaaro i roto i te kawe ia hiko tutuki e te tikanga o te iahiko tāupe i te putanga.

Tauira ki te triac ohie

marama dimmer ki thyristor ohie he pai hāngai hoki pana-pātene tauira. pūnaha tiaki, ka rite ki te tikanga, e kore e te reira. Kua hanga hoapā katoa i roto i te regulator o parahi. ātete mōrahi ki thyristor tikanga e taea te tu i te kokoru 10 V. hoki e ruarua hāngai pūmana hurihuri. e kore e taea e ki te mahi parenga pū ki taua tauwehe. he tika ki te taumata tiketike o te ātete kino i roto i te ara iahiko tenei.

whakatakotoria tino onge hoki parenga High-auau. I roto i tenei take, ka waiho nui te taumata haruru, a ka arahi ki te kikī o te ngōhiko zener. Ki te kōrero tatou e pā ana ki te rama tepu mua, he reira pai ki te whakamahi i te rua thyristor tikanga ki parenga waea. Ko te āriponga e ratou i te taumata tika tiketike. Ratou uaua overheat, te mana toreretanga i roto i te toharite, ko te a tawhio noa 2 Watts.

Ko te whakamahi o ngā pūnga tāupe i roto i te ara iahiko

Na roto i te whakamahi o ngā pūnga tāupe kua tutuki te huringa maeneene o te wherikotanga o rama aano atu. I roto i tenei take, mahi tino rerekē te tauira -hiko. He pai mō te 12 Watts te nuinga o transistors mo enei pūnga iahiko. Me te tiaki i te ngaohiko tāuru i 19 V. kia whakarato hoki te reira i mo te whakamahi o fuses. Kei te tikanga Thyristors whakamahia ki māka KU202. E pai ngā waka ratou mo putanga hurihuri. Hei whakanui i potentiometers whakarea kawe ia whakamahia ki whakakā whatunga.

Ko te unijunction pūrere pūmana

Kei te mohiotia Unijunction whakamarama dimmer mo tona tapatahi. Parenga i roto reira, ka rite ki te tikanga, e whakamahia ana e 4 Watts. I roto i tenei take, te ngaohiko mōrahi ko reira e taea ki te pupuri i 14 V. A, no te te whakamahi i te reira, he mea nui ki te mau i roto i te ngakau e ia kia kemo te marama. Ko te fuses i roto i nga whakaaro e whakamahia tino uaua.

I mōrahi e taea te waiho tauanga tāuru nāianei 4 momo A. Thyristors KU202 ahei o te pūnaha taua ki te mahi anake mo te tokorua ki te piriti ngōhiko. Me te pūrere triac hono i runga i te parenga. Hei hono i te dimmer ki te rama, e hiahia ana koe ki te horoi i te hoapā katoa. Ko te whare mo te pūrere he mea nui ki te tono i te uruhanga. I roto i tenei take, ka kia whai te haumaru mahi.
