Basa rema "solid state relay"
MaSolid-state relay chaizvoizvo zvishandiso zvekuchinja zvisingabatanidzi zvine hunhu hwe relay zvinoshandisa zvishandiso zve semiconductor kutsiva ma contact emagetsi echinyakare sezvishandiso zve switching. Single-phase SSR mudziyo unoshanda une materminal mana, une materminal maviri ekudzora ekupinda, materminal maviri ekuburitsa, uye pakati pe input ne output. Kune optical isolation, mushure mekunge input terminal yawedzera DC kana pulse signal kune imwe current value, output terminal inogona kushandurwa kubva pa off state kuenda pa on state. Dedicated solid state relay inogona kuva nemabasa ekudzivirira short circuit, overload protection uye overheat protection, uye combination logic curing package inogona kuita intelligent module inodiwa nemushandisi, iyo inogona kushandiswa zvakananga mu control system.
Zvinhu zveSolid State Relays
Ma "Solid-state relay" ma "switch" emagetsi asingabatanidzwe ane basa rekuzviparadzanisa. Hapana zvikamu zve "mechanical contact" panguva yekuchinja. Nokudaro, pamusoro pemabasa akafanana ne "electromagnetic relay", ma "solid-state relay" anoenderanawo ne "logic circuits", anodzivirira vibration uye mechanical shock, uye ane nzvimbo dzisina muganho dzekuisa. , ane hunyoro hwakanaka, haapindi mu "mold" uye haapindi mu "corrosion performance", ane hunhu hwakanaka mukudzivirira kuputika uye kusvibiswa kwe "ozone", ane simba shoma rekupinda, ane simba rakawanda, ane simba rakaderera rekudzora, anoenderana zvakanaka ne "electromagnetic", ane ruzha rwakaderera uye ane frequency yepamusoro yekushanda.

Zvakanakira uye zvakaipa zve solid state relay
Chekutanga, zvakanakira zve solid state relay
1. Hupenyu hwepamusoro hwebasa uye kuvimbika kwakanyanya: SSR haina zvikamu zvemakanika, uye ine zvishandiso zve solid-state kuti ipedzise basa rekubata. Sezvo pasina zvikamu zvinofamba, inogona kushanda munzvimbo dzakanyanya kuvhunduka uye dzakadengenyeka. Nekuda kwehunhu hwezvinhu zvinoumba solid state relay Hunhu hunosarudza hupenyu hurefu uye kuvimbika kwakanyanya kwe solid state relay;
2. Kunzwa kwakanyanya, simba rekudzora rakaderera uye kukwirirana kwakanaka kwemagetsi: ma solid state relay ane huwandu hwakakura hwemagetsi ekupinda uye simba rekutyaira rakaderera, uye anoenderana nemazhinji ma logic integrated circuits asina ma buffers kana madhiraivha;
3. Kuchinja nekukurumidza: solid state relay inoshandisa solid state, saka kumhanya kwekuchinja kunogona kubva pamamirisekonzi mashoma kusvika kumamicroseconds mashoma;
4. Kupindirana kwemagetsi kudiki: Solid state relay haina "coil" inopinza, haina arcing uye rebound, nokudaro ichideredza kupindirana kwemagetsi. Mazhinji eAC output solid state relays iswitch ye zero-voltage, iyo inobatidzwa pa zero voltage uye zero current. dzima, zvichideredza kukanganiswa kamwe kamwe mu current waveform, nokudaro zvichideredza mhedzisiro ye switching transients.
Chechipiri, kuipa kwe solid state relays
1. Kudonha kwevoltage yechubhu mushure mekutenderera kwemhepo kwakakura, kudonha kwevoltage yemberi yethyristor kana bi-phase thyristor kunogona kusvika 1~2V, uye kumanikidzwa kwe saturation ye high-power transistor kuri pakati pe1~2V. Conduction electric ancestor yakakurawo kupfuura contact resistance ye mechanical contact;
2. Mushure mekunge mudziyo we semiconductor wadzimwa, panogona kunge paine kubuda kwemvura kwema microamps akawanda kusvika kuma milliamps akawanda, saka kupatsanurwa kwemagetsi kwakakodzera hakugone kuwanikwa;
3. Nekuda kwekudonha kukuru kwevoltage yechubhu, kushandiswa kwesimba uye kugadzirwa kwekupisa mushure mekufambisa magetsi kwakakurawo, huwandu hwema "high-power solid state relay" hwakakura zvikuru kupfuura hwema "electromagnetic relay" ane simba rimwe chete, uye mutengo wacho wakakwirawo;
4. Hunhu hwekupisa hwezvikamu zvemagetsi uye kugona kwekudzivirira kukanganiswa kwemasekete emagetsi hazvina kunaka, uye kuramba mwaranzi kwakadererawo. Kana pasina matanho anoshanda anotorwa, kuvimbika kwebasa kuchava kwakaderera;
5. Ma "Solid-state relay" anonyanya kukanganiswa nekuwedzerwa kwesimba, uye anofanira kudzivirirwa nema "fast fuses" kana kuti ma "RC damping circuits". Zviri pachena kuti mutoro we "solid-state relay" une chekuita nekupisa kwemhepo. Kana tembiricha yakwira, simba rekutakura rinodzikira nekukurumidza.
