Un solid state relay, kana SSR (Solid State Relay), mudziyo unoshanda zvakafanana seyakajairika relay, asi ine zvimwe zvakanakira pamusoro payo sezvauchaona muchinyorwa chino. Kana iwe usingayeuke zvakanaka kuti relay chii kana kuti ndeyei, iwe unogona zvakare Ona rumwe ruzivo mune chimwe chinyorwa ichi.
Tataura izvozvo, ngatione zvese zvaunoda kuziva nezve izvi mudziyo wemagetsi:
Chii chinonzi electromechanical relay?
Un electromagnetic relay, inowanzodaidzwa kunzi relay, mudziyo wemagetsi unoshandiswa kudzora dunhu remagetsi kuburikidza nekushandiswa kweiyo electromagnetic coil. Iyo inonyanya kushandura iyo inoshandiswa nekuisa kana kubvisa magetsi emagetsi mune relay coil. Kana iyo coil ikasimbiswa, inogadzira simba remagineti rinokwezva kana kudzoreredza chibatiso kana kushandura mukati meiyo relay, kuvhura kana kuvhara magetsi emagetsi, zvichienderana nekuti ari NC kana NO, sezvatakaona mune chimwe chinyorwa chandinokukurudzira. verenga pakutanga.
Aya mareyi anoshandiswa mumhando dzakasiyana dzekushandisa kuita mabasa akadai kuchinja kwemasimba emagetsi emagetsi emagetsi emagetsi kana kuparadzaniswa kwemagetsi pakati pemaseketi maviri anoshanda nemhando dzakasiyana dzezvino, senge DC neAC. Izvo zvinonyanya kubatsira mumamiriro ezvinhu apo iwe unofanirwa kudzora dunhu kure kana iwe kana iwe uchida kuparadzanisa control redunhu kubva kune yakakwirira simba. Relays inogona kuwanikwa mumhando dzakasiyana dzemidziyo uye masisitimu, kubva kumidziyo yemumba uye maindasitiri midziyo yekudzora uye otomatiki masisitimu.
Chii chinonzi solid state relay?
Un Solid mamiriro ataure chinhu chemagetsi chinoshandura chinobvumira kuyerera kwemagetsi emagetsi kana diki ikozvino inoshandiswa kune zviteshi zvayo zvekutonga, kana kudzivirira kana pasina ikozvino inoshandiswa. Ndiko kuti, mupfungwa iyi yakafanana zvikuru nekushanda kweiyo yakajairika relay.
Aya akasimba mamiriro ekudzoreredza anosanganisira sensor inopindura kune yekudzora chiratidzo, yemagetsi solid state switch inobata dunhu rekutakura, uye coupling meshini iyo inomutsa switch pasina kudiwa kwekufambisa ma mechanical components, sepanyaya ye electromagnetic. Kune rimwe divi, idzi relay dzinogona kugadzirwa kuti dzishandure zvose AC uye DC ikozvino.
Kuita kuti izvi zvigoneke pasina zvidimbu zvinofamba, simba semiconductors, senge thyristors uye transistors, kudzora mafambiro anosvika anopfuura zana amperes musimba. Uyezve, kuve yakasimba, ivo vanoratidzwa nekugona kwavo kushandura nekumhanya kwakanyanya, muhurongwa hwemamilliseconds, zvichienzaniswa nemagetsi emagetsi, uye havana ma mechanical contacts anopera nekufamba kwenguva. Zvisinei, hazvisi zvose zvakanakira, sezvatichaona gare gare.
Pakuparadzaniswa kwemagetsi pakati pemaseketi maviri, chiratidzo chekudzora chinosanganiswa nedunhu rekutonga, uye mazhinji maSSR anoshandisa optical coupling. Izvi zvinoreva kuti simba rekutonga rinoita kuti mukati me LED inovhenekera uye inomutsa photosensitive diode (photovoltaic), iyo inodzora TRIAC (inoshandiswa muAC), SCR kana MOSFET (inowanzova imwe kana yakawanda yakafanana neCC) kuchinja nekuenda kubva pakavhurika kuenda pakavharwa kana zvakasiyana…
Zvakanakira uye kuipa kweiyo solid state relay
Sezvaunogona kufungidzira, iyo solid state relay ine zvinobatsira kupesana ne electromechanical relay, yakadai se:
- Saizi diki.
- Low voltage operation, ine activation inobvira kubva 1,5V kana pasi.
- Sezvo isingabatanidzi zvikamu zvinofamba, yakanyarara zvachose.
- Iwo anokurumidza kupfuura magineti, sezvo aine nguva dzekupindura dzemamilliseconds.
- Nekusava nemechani zvikamu zvinosakara kana zvinobatika zvinodzikira pamhepo yakakwira, idzi relay dzinovimbika uye dzinogara kwenguva refu.
- Iko kupikisa kunobuda kunoramba kuripo pasinei nekushandiswa.
- Bounce-yemahara yekubatanidza, kudzivirira kuchinjika mukubata switching.
- Haaburitse sparks kana magetsi arcs anogona kuve nengozi munzvimbo dzinopisa.
- Kuwedzera kushingirira kuvhundutsa, vibrations, nezvimwewo, sezvo isina zvikamu zvinofamba zvinogona kutyora.
- Iwo haaburitse mafungu emagetsi anogona kukonzera kukanganisa mune mamwe maturusi.
Kufanana nezvose, ivo vanewo zvayakaipira, sei:
- Vanobudisa kupisa nekuda kwekupikisa, izvo zvinoreva kurasikirwa.
- Iyo polarity yezvinobuda inogona kukanganisa solid state relays, chimwe chinhu chisingaitiki mumagetsi emagetsi.
- Nekuda kwekugona kwavo kukurumidza kushandura, solid state relays inogona kusangana nekuchinja kwenhema nekuda kwekuremerwa kwenguva pfupi.
- Vanowanzoramba vari munharaunda yakavharwa kana paine chikanganiso, nepo electromechanical relays inowanzoramba iri munzvimbo yakazaruka. Izvi zvinogona kuve zvakanaka kune mamwe maapplication, kunyangwe zvisiri zveese...
Applications
Solid State Relays (SSR) inogona kushandiswa mukati kuwanda kwekushandisa, sei:
- Kudzora kudzora mune zvese DC uye AC, kudzora maheater emagetsi, mwenje, mota, midziyo, kudziyisa, kutonhora, pombi dzemvura dzekudiridza, nezvimwe. Semuyenzaniso, anogona kushandiswa dunhu rinoita feni kana tembiricha ichikwira kune mamwe madhigirii, uchishandisa tembiricha sensor.
- Industrial automation. Nekuti ari azvino-anodzorwa switch, anogona kushandiswa mumaindasitiri ekudzora masisitimu e automation yemichina uye maitiro.
- Midziyo yekurapa yakadai semichina yeMRI, michina yekuongorora kiriniki, uye masisitimu ekurapa ekudzora simba nemidziyo yemidziyo iyi.
- Resistive uye reactive load control. Solid state relays inobatsira mumashandisirwo apo mitoro inodzivirira (senge hita) uye mitoro inotenderera (yakadai semotor) inoda kuchinjika nekuda kwekugona kwavo kubata dzakasiyana siyana dzemhando dzekutakura.
- Masisitimu ekufambisa, senge munjanji uye zvifambiso zvevoruzhinji, maSSR anoshandiswa kudzora masaini, mwenje, uye masisitimu ekudzora traffic.
- Vamwe…
Kupi kutenga yakasimba state relay?
Kana iwe uchida tenga yakasimba state relay, unogona kuzvitenga zvishoma muzvitoro zvine hunyanzvi kana pamapuratifomu ekutengesa epamhepo seAmazon:
Shandisa iyo yakasimba state relay neArduino
Kushandisa solid state relay neArduino, kubatana kuri nyore, kunyanya kana ukashandisa SSR module. Kuti ubatanidze iyi relay kuArduino board, unofanirwa gadzira zvinotevera zvinongedzo:
- DC +: iyi relay yekupinza yakabatana ne5v yekubatanidza yeArduino board.
- DC-: Iyi imwe yekupinza yerelay inobatanidza neGND kana pasi kubatana kweArduino board.
- CH1: kana iri single-channel solid state relay, senge yatiri kuzopa semuenzaniso, iyi relay yekuisa ichave yakabatana neArduino digital goho rekutonga, semuenzaniso, iyo D9.
- HAPANA / C: ndizvo zvinobuda zveiyo solid state relay iyo ichave yakabatana kune mudziyo watinoda kudzora. Somuenzaniso, girobhu. Funga nezvedhetate reiyo relay yaunotenga, uye iyo yakatemerwa miganhu. Semuenzaniso, vamwe vanongoshivirira mutoro we 250V AC uye huwandu hwepamusoro hwe2A, ita shuwa kuti haupfuure ...
Tataura izvozvo, zvino ngationei yaizorongwa sei, uchishandisa iyi muenzaniso sketch:
const int pin = 9; //Pin de control del relé en el que lo hayas conectado, en este caso D9.
void setup()
{
Serial.begin(9600); //Iniciar puerto serie
pinMode(pin, OUTPUT); //Definir pin D9 como salida para el envío de señal.
}
void loop()
{
digitalWrite(pin, HIGH); // Poner el D9 en estado alto para activar el relé
delay(5000); // Esperar 5 segundos
digitalWrite(pin, LOW); // Poner el D9 en estado bajo, para desactivar.
delay(5000); // Esperar 5 segundos
}
Sezvauri kuona, iri nyore kwazvo kodhi, saka unogona kuigadzirisa uye kudzidza mashandisiro eiyo relay. Muchiitiko ichi isu takangogadzira loop kuitira kuti relay igare ichibva kune imwe nyika kuenda kune imwe ...
