Desai: zano uye midziyo. Haizoshandisi vane dimmers

Special anotonga inoshandiswa kugadzirisa nokupenya incandescent mwenje. mano aya anonziwo dimmers. Ivo kuripo mushanduro dzakasiyana, uye, kana zvakakodzera, ari chitoro unogona nguva dzose kusarudza zvakakodzera womuenzaniso. Zvikurukuru, ivo kutsiva dunhu mudariki munguva incandescent rambi. The nyore nadzurudzo unosanganisira muhombe controller pamwe chinyoreso. Kana kuisa pasi luminance chinoumba zvimwe kuchinja magetsi rinodyiwa.

Kana iwe yeuka mazuva ekare, chidhiraivho nekuwedzera kupenya haisi kushandiswa. Asi, chinokosha dimmers yakaiswa. Uchibatsirwa wavo, unogona zvakare kudzorwa fluorescent mwenje. Kazhinji, pamwe mabasa Vakatsungirira zvakanaka, asi vakanga chimwe chinetso. Hwakabatana pamwe chete kudyiwa magetsi. Sezvambotaurwa, regulators ano vasapedza magetsi kana akashandiswa kwete zvakazara chinzvimbo. In nyaya resistances kuti mutemo haushandi. Shoma simba wakapedza magetsi uyewo kufadza. Nekumwisa iyi nyaya vatendeukira kuchipisa.

Scheme kwakajairika regulator

nokuda kwenhamo redunhu Simple kunosanganisira kushandiswa Linear potentiometer mhando, uye peya transistors nesimba pasi. Kudzvinyirira yakakwirira maitikiro capacitors zvinoshandiswa munyika. The cores namano ino mhando vanoda chete mhando ferrite. Pakarepo pamberi chinouraya unoiswa kuna Shockley diode thyristor.

How kutsausa raundi kuti mwenje?

To tafura rambi pamwe nokuda kwenhamo vakashanda anowanzoita, tarisa voltage mhiri semiconductor. Izvi zvinogona kuitwa pachishandiswa kwakajairika tester. Next, kundotarira bhodhi girobhu racho. Kana wakaiswa odnokalnogo mhando, zvose zvaitwa zvikuru nyore. The goho semiconductors inokosha kunofambidzana Outlet mawindo, ine kunaka polarity. Panyaya iyi kunonyanyisa nemishonga anofanira kuva 3 ohms. Kuedza mudziyo, unofanira tenderera ari controller uye murinde pamwe chete nguva nokupenya incandescent mwenje.

Nekuisa kusunda bhatani ari rambi

Kudzora nokupenya incandescent mwenje ushande zvakanaka, zvakakosha kuziva mudziyo utariri bhodhi. Next, unofanira kubatanidza ako vokukurukura zvose. Kana redunhu rinoshandiswa munhu multi-mugero, ari voltage pairi iri ndakaongorora tester. Remubatanidzwa zvakananga contactsGoogle kutakurwa brazing. Zvakakosha panguva iyoyo panguva kushanda hazvirevi kukuvadzwa resistors. Uyezve, unofanira vatarisire wiring kuputira. Asati atendeuka pamusoro controller uchida kutarisa kwokubatana zvose pakasimba. Mushure simba wedzerai zvinokosha kuti kuedza kushandura nokupenya nokutsikirira bhatani.

High Kupenya anotonga

Mukuru-voltage nokuda kwenhamo chiedza, sezvinoita mutemo, anogona kuwanikwa dzemitambo. Kune incandescent mwenje anoshandiswa simba zvikuru, uye mudziyo vanofanira kukwanisa kumira mitoro inorema. Triacs kuti chinangwa ichi, mukuru-voltage (anozivikanwa ne KU202) anoshanda. Nedambudziko transistors anoshandiswa Zvisinei, zvatinosiita okunatsiridza aro vari kuisa.

Diode mabhiriji soldered pedyo thyristors uye zvakakodzera kuti kutsanya chiratidzo hutachiwana. Zener diodes kazhinji dzinogona kuwanikwa nemuumbi D814. Vari muchitoro zvinodhura chaizvo, uye izvi zvinofanira kufungwa nezvazvo. Shanduka resistors munyika vanokwanisa kukurira voltage panogumira 60 ohms. Panguva ino, kwakajairika dzomuzana fused pamwe ohms 5 chete.

Models vane zvakarurama resistors

Desai pamwe resistors iyi mhando rakagadzirirwa incandescent avhareji simba. Zener diodes mune iyi, 12 V shanduka resistors regulators hadziwanzowaniki. Low maitikiro okunatsiridza zvinogona kushandiswa. Kuwedzera conductivity coefficient mune iyi zvinokwanisika nokuwedzera kwenhamba capacitors. Nokuti triac vanofanirwa kuiswa vaviri vaviri. Panyaya iyi, kupisa nazvo vachava usingashandi. Negative nemishonga samambure kazhinji dambudziko rakakura. Zadzisa pakupedzisira inotungamirira Kuparara zener diode. Electrolytic capacitors vane yakaderera-kakawanda ruzha kurarama zvikuru kubudirira. The chikuru chinhu pamwe ichi - regai kupa inopinza mukuru voltage kune mwenje.

The regulator redunhu resistors vysokomegaomnymi

Kupenya kudzora ichi mhando zvingashandiswa kudzora rakasiyana-siyana nemarambi. Scheme nayo unotora vysokomegaomnye resistors AC, uyewo kwakajairika zener. Thyristor iyi nyaya iri pedyo condenser. Kuderedza muganhu kakawanda nyanzvi vanowanzoshandisa fiyuzi mhando. Vanokwanisa kukurira mutoro 4 A. At ichi muganhu kakawanda kuti goho achava vaifanira 50 Hz. talk chinangwa chiyamuro voltage Triacs angakudzivisai pa 15 V.

Haizoshandisi vane regulators FET

With nokuda kwenhamo haizoshandisi pamusoro FET hwokuratidza kudzivirira zvakanaka. Short-mudunhu mugadziriro kuitika chaizvo kashoma, uye zvechokwadi kwakabatsira. Uyezve, tapota cherechedza kuti Zener regulator inogona kushandiswa chete KU202 chokuguma. Muchiitiko chino, ivo vanokwanisa kushanda pamwe yakaderera maitikiro resistors uye kukunda kukanganiswa kwazvo. Triacs mumatunhu iri seri resistors. The vakaomerwa kurwisa munyika vanosungirwa nekuchengetedzwa pa 4 ohms. The voltage pa mazano resistors abate ndezvomuzana 18 V. muganhu kakawanda, akavapindurawo, haafaniri kupfuudza 14 Hz.

Regulator pamwe trimmer

Desai pamwe trimmer capacitor zvinogona zvinobudirira kushandiswa kugadzirisa simba fluorescent mwenje. Haizoshandisi muchiitiko ichi chinofanira kuiswa kuseri diode zambuko. Zener diodes mudunhu zvaidiwa kukanganiswa kudzvinyirira. Resistors shanduka mhando iri kazhinji vakaomerwa impedance anodzokororwa pa 6 ohms.

Kana ichi thyristors anoshandiswa chete kuchengeta voltage panguva yakakodzera chechetere. Triacs kuburikidza pacharo anokwanisa kupfuura kuitika kuti azvipire A. fiyuzi mhando controllers anenge 4 hadziwanzowaniki. Dambudziko mano kwakadaro magetsi conductivity kunokwanisika kuburikidza shanduka resistor panguva goho.

Model nokungoti triac

chiedza nokuda kwenhamo nyore thyristor ndiyo yakanakisisa akakodzera kuti kusunda-bhatani yokutevedzera. kuchengetedzwa ezvinhu, sezvo mutemo, hazvina. contactsGoogle All vari regulator zviri zvemhangura. Kunonyanyisa kuramba kwakajairika thyristor anogona kukunda Inlet 10 V. For muhombe controllers vari havaratidzi akakodzera. Zvakarurama resistors vane regulators kwakadaro havagoni kushanda. Izvi imhaka yakakwirira pamwero yakaipa mumweya kutenderera.

High-kakawanda resistors akagadzira zvisinganyanyi kuitika. Panyaya iyi, ruzha pamwero achava zvinokosha uye kuchaita kuti zadzisa yacho zener diode. Kana isu nezvazvo zvatinosiita tafura marambi, zvakanakisisa kushandisa kwakajairika thyristor peya pamwe waya resistors. The conduction hazvina kumbonyanya yakakwirira chechetere. Ivo kashoma overheat, simba nounzenza mu avhareji iri kumativi 2 watts or.

Kushandiswa shanduka capacitors mudunhu

Uchishandisa shanduka capacitors makawana munhu anotsvedzerera nokuchinja nokupenya incandescent mwenje. Panyaya iyi, iyo electrolytic mhando kushanda zvakasiyana. Transistors nokuti capacitors aya akakodzera watts or kupfuura 12. The chiyamuro voltage anofanira kuchengetedzwa pa 19 V. Zvinofanira rinhi kushandisa fuses. Thyristors kazhinji kushandiswa rokuisa chiratidzo KU202. Vari unonyatsokodzera muhombe shanduro. Kuwedzera conductivity coefficient potentiometers rinoshandiswa nomumbure haizoshandisi.

The mudziyo controller unijunction

Unijunction chiedza nokuda kwenhamo inozivikanwa nyore. Resistors mairi, sezvo mutemo, yaishandiswa 4 watts or. Panyaya iyi, kufadza voltage zviri kukwanisa kuiita panguva 14 V. Kana kurishandisa, zvakakosha kuyeuka kuti kunyange chiedza anogona kudzima. The fuses namano anoshandiswa zvikuru kazhinji.

At kunonyanyisa yavose sezvavakatarirwa ano chiyamuro anogona kusiya 4 A. Thyristors KU202 mhando aigona kudaro hurongwa kushanda chete kuti vaviri ine diode zambuko. The triac mudziyo unofanira kwakabatana pamusoro resistor. Kubatanidza nokuda kwenhamo kune mwenje, unofanira kuchenesa ose vokukurukura. Dzimba nokuti mudziyo zvakakosha kushandisa dielectric. Panyaya iyi, basa kuchengeteka kuchaitwa.
