Udindo wa solid state relays
Maulumikizidwe a Solid-state ndi zida zosinthira zosalumikizana zomwe zili ndi mawonekedwe olumikizirana omwe amagwiritsa ntchito zida za semiconductor m'malo mwa zida zamagetsi zachikhalidwe ngati zida zosinthira. Single-phase SSR ndi chipangizo chogwiritsa ntchito ma terminal anayi, pomwe ma terminals awiri olowera, ma terminals awiri otulutsa, komanso pakati pa zolowetsa ndi zotulutsa. Pazodzipatula zowoneka bwino, cholumikizira cholowera chikawonjezera chizindikiro cha DC kapena pulse pamtengo wina wapano, malo otulutsa amatha kusinthidwa kuchoka kudziko kupita ku boma. The odzipereka olimba boma relay akhoza kukhala ndi ntchito za chitetezo dera lalifupi, chitetezo mochulukira ndi kutenthedwa kutenthedwa, ndi kuphatikiza logic kuchiritsa phukusi akhoza kuzindikira gawo wanzeru chofunika ndi wosuta, amene angagwiritsidwe ntchito mwachindunji dongosolo ulamuliro.
Mawonekedwe a Solid State Relays
Solid-state relay ndi ma switch amagetsi osalumikizana ndi ntchito yodzipatula. Palibe magawo olumikizana ndi makina panthawi yosinthira. Chifukwa chake, kuwonjezera pa ntchito zomwezo monga ma electromagnetic relays, ma relay olimba amagwirizananso ndi mabwalo omveka, osamva kugwedezeka ndi kugwedezeka kwamakina, ndipo amakhala ndi malo opanda malire. , ili ndi chitetezo chabwino cha chinyezi, mildew-proof ndi anti-corrosion performance, imagwira bwino ntchito poletsa kuphulika ndi kupewa kuwononga ozoni, mphamvu yochepa yolowera, kukhudzidwa kwakukulu, mphamvu yochepetsera mphamvu, kugwirizanitsa kwamagetsi, phokoso lochepa komanso maulendo apamwamba ogwiritsira ntchito.

Ubwino ndi kuipa kwa solid state relays
Choyamba, ubwino wa olimba boma relays
1. Moyo wautumiki wapamwamba ndi kudalirika kwakukulu: SSR ilibe zigawo zamakina, ndipo ili ndi zipangizo zolimba kuti amalize ntchito yolumikizana. Popeza palibe ziwalo zosuntha, zimatha kugwira ntchito modzidzimutsa komanso kugwedezeka. Chifukwa cha chibadwidwe cha zigawo zomwe zimapanga malo olimba a relay Makhalidwe amatsimikizira moyo wautali ndi kudalirika kwakukulu kwa relay state relay;
2. Kumverera kwakukulu, mphamvu zochepetsera mphamvu komanso kugwirizanitsa kwamagetsi: ma relay olimba ali ndi njira zambiri zolowera magetsi ndi mphamvu zochepa zoyendetsa galimoto, ndipo zimagwirizana ndi mabwalo ambiri osakanikirana opanda ma buffers kapena madalaivala;
3. Kusintha kwachangu: chigawo cholimba chimagwiritsa ntchito malo olimba, kotero kuti liwiro la kusintha likhoza kukhala kuchokera ku milliseconds kupita ku ma microseconds ochepa;
4. Kusokoneza kwakung'ono kwa ma electromagnetic: Kulumikizana kolimba kwa state state kulibe "koyilo" yolowera, palibe ma arcing ndi rebound, motero kumachepetsa kusokoneza kwamagetsi. Ma relay ambiri a AC olimba ndi zero-voltage switch, yomwe imayatsidwa paziro voteji ndi ziro panopa. kuzimitsa, kuchepetsa kusokoneza mwadzidzidzi mu mawonekedwe a mafunde apano, potero kuchepetsa zotsatira za kusintha kwa transients.
Chachiwiri, kuipa kwa olimba boma relays
1. Kutsika kwamagetsi kwa chubu pambuyo pa conduction ndi kwakukulu, kutsika kwapakati kwa thyristor kapena bi-phase thyristor kumatha kufika 1 ~ 2V, ndipo kuthamanga kwa machulukidwe a transistor apamwamba kwambiri kuli pakati pa 1 ~ 2V. Kholo lamagetsi la conduction ndilokulirapo kuposa kukana kukhudzana ndi kukhudzana kwamakina;
2. Pambuyo pozimitsa chipangizo cha semiconductor, pangakhalebe kutayikira kwa ma microamp angapo mpaka ma milliamp angapo, kotero kuti kudzipatula kwamagetsi koyenera sikungapezeke;
3. Chifukwa cha kutsika kwakukulu kwa voteji ya chubu, mphamvu yogwiritsira ntchito mphamvu ndi kutentha kwa kutentha pambuyo pa conduction imakhalanso yaikulu, kuchuluka kwa mphamvu zamphamvu zolimbitsa thupi zimakhala zazikulu kwambiri kuposa zomwe zimagwirizanitsa ma electromagnetic relays ofanana, ndipo mtengo wake ndi wokwera;
4. Makhalidwe a kutentha kwa zipangizo zamagetsi ndi mphamvu zotsutsana ndi kusokoneza kwa mabwalo amagetsi ndi osauka, ndipo kukana kwa ma radiation kulinso kosauka. Ngati palibe njira zogwirira ntchito, kudalirika kwa ntchito kudzakhala kochepa;
5. Ma relay olimba amakhudzidwa kwambiri pakuchulukira, ndipo amayenera kutetezedwa ndi ma fuse othamanga kapena ma daping circuits a RC. Katundu wa ma relay olimba-boma mwachiwonekere amagwirizana ndi kutentha kozungulira. Kutentha kukakwera, mphamvu ya katundu idzatsika mofulumira.
