Basa rehurumende yakasimba relays
Solid-state relays ndeyechokwadi isiri-yekubata switching zvishandiso zvine relay maitiro anoshandisa semiconductor midziyo kutsiva echinyakare magetsi ekubata semachinjiki emidziyo. Single-phase SSR ichina-terminal inoshanda mudziyo, iyo miviri yekuisa yekudzora materminal, maviri ekubuda materminal, uye pakati pekupinda nekubuda. Zvekuzviparadzanisa nevamwe, mushure meiyo yekuisa terminal yakawedzera iyo DC kana pulse siginecha kune imwe yazvino kukosha, iyo inobuda terminal inogona kushandurwa kubva kune imwe nyika kuenda kune imwe nyika. Iyo yakatsaurirwa yakasimba nyika relay inogona kuve nemabasa ekudzivirira dunhu repfupi, kudzivirira kuwanda uye kudzivirira kupisa, uye musanganiswa wepfungwa yekurapa pasuru inogona kuona iyo yakangwara module inodiwa nemushandisi, inogona kushandiswa zvakananga muhurongwa hwekutonga.
Zvimiro zveSolid State Relays
Solid-state relays isiri-inobata magetsi switch ine basa rekuzviparadzanisa nevamwe. Iko hakuna michina yekubatanidza zvikamu panguva yekuchinja maitiro. Naizvozvo, mukuwedzera kune mamwe mabasa akafanana nemagetsi emagetsi relays, solid-state relays zvakare inoenderana neane logic maseketi, anopokana nekuzunguzika uye kuvhunduka kwemuchina, uye ane nzvimbo dzisingaperi dzekuisa. , ine hunyoro-uchapupu hwakanaka, mildew-proof uye anti-corrosion performance, kuita kwakanakisa mukudzivirira-kuputika uye kudzivirira kusvibiswa kwe ozone, simba rekuisa rakaderera, kunzwisiswa kwepamusoro, simba rekudzora rakaderera, kuenderana kwemagetsi, kuderera kweruzha uye yakanyanya kushanda frequency.

Zvakanakira uye kuipa kweiyo solid state relays
Kutanga, zvakanakira solid state relays
1. Upenyu hwebasa repamusoro uye kuvimbika kwepamusoro: SSR haina zvikamu zvemagetsi, uye ine michina yakasimba-yehurumende kuti ipedze basa rekubatana. Sezvo pasina zvikamu zvinofamba, zvinogona kushanda mukuvhunduka kukuru uye nharaunda dzinodedera. Nekuda kwechimiro chechimiro chezvikamu zvinoumba iyo yakasimba state relay Zvimiro zvinotarisa hupenyu hurefu uye kuvimbika kwepamusoro kweiyo solid state relay;
2. Kunzwa kwepamusoro, simba rekudzora rakaderera uye kuenderana kwakanaka kwemagetsi: solid state relays ine yakakura yekuisa voltage renji uye yakaderera simba rekutyaira, uye inowirirana neakawanda logic akabatanidzwa maseketi asina buffers kana vatyairi;
3. Kukurumidza kushandura: iyo yakasimba relay relay inoshandisa nyika yakasimba, saka kukurumidza kushandura kunogona kubva kune mashoma milliseconds kusvika kune mashoma microseconds;
4. Diki remagetsi remagetsi: Iyo yakasimba state relay haina yekupinda "coil", haina arcing uye rebound, nokudaro kuderedza kukanganiswa kwemagetsi. Yakawanda AC inobuda solid state relays ndeye zero-voltage switch, iyo inobatidzwa pa zero voltage uye zero ikozvino. kudzima, kuderedza kuvhiringika kwakangoerekana kwaitika mune yazvino waveform, nekudaro kudzikisa mhedzisiro yekuchinja kwenguva pfupi.
Chechipiri, kuipa kweiyo solid state relays
1. Kudonhedzwa kwemhepo yehubhu mushure mekuita kwakakura, kudonha kwemhepo kumberi kwe thyristor kana bi-phase thyristor inogona kusvika 1 ~ 2V, uye mhepo yekuzara kwepamusoro-simba transistor iri pakati pe1 ~ 2V. Iyo conduction yemagetsi tateguru zvakare yakakura kupfuura yekubata kupikisa kweiyo mechanical contact;
2. Mushure mekunge mudziyo we semiconductor wadzimwa, panogona kunge paine kubuda kweazvino kwema microamps akawanda kune akati wandei milliamps, saka yakanakira yekuzviparadzanisa nemagetsi haigone kuwanikwa;
3. Nekuda kwekudonha kukuru kwehubhu yehubhu, kushandiswa kwemagetsi uye kugadzirwa kwekupisa mushure mekuita kwakakurawo, huwandu hwesimba repamusoro-simba relays relays yakakura kwazvo kupfuura iyo yemagetsi emagetsi ehumwe simba, uye mutengo wakakwirawo;
4. Mamiriro ekushisa ezvikamu zvemagetsi uye simba rekudzivirira-kupindira kwemaseketi emagetsi harina kunaka, uye kushorwa kwemwaranzi zvakare kwakashata. Kana pasina matanho anobudirira anotorwa, kuvimbika kwebasa kuchave kwakaderera;
5. Solid-state relays inonzwa zvakanyanya kune kuwandisa, uye inofanira kuchengetedzwa nekukurumidza fuse kana RC damping circuits. Kuremerwa kweiyo solid-state relays zviri pachena kune hukama neambient tembiricha. Kana kutonhora kuchikwira, simba rekutakura richadonha nokukurumidza.
