Udindo wa ma solid state relay
Ma relay a Solid-state kwenikweni ndi zida zosinthira zosakhudzana ndi ma relay omwe amagwiritsa ntchito zida za semiconductor m'malo mwa ma contact amagetsi achikhalidwe ngati zida zosinthira. SSR ya gawo limodzi ndi chipangizo chogwira ntchito cha ma terminal anayi, chomwe chili ndi ma terminal awiri owongolera olowera, ma terminal awiri otulutsa, komanso pakati pa ma input ndi otulutsa. Pakulekanitsidwa kwa kuwala, pambuyo poti terminal yolowetsayo yawonjezera chizindikiro cha DC kapena pulse ku mtengo winawake wamagetsi, terminal yotulutsa imatha kusinthidwa kuchoka pa off state kupita pa on state. Solid state relay yodzipereka imatha kukhala ndi ntchito zoteteza ma short circuit, chitetezo cha overload ndi chitetezo cha overheat, ndipo phukusi lophatikizana la logic curing limatha kukwaniritsa gawo lanzeru lomwe wogwiritsa ntchito amafunikira, lomwe lingagwiritsidwe ntchito mwachindunji mu dongosolo lowongolera.
Makhalidwe a Solid State Relays
Ma relay a Solid-state ndi ma switch amagetsi osakhudzana ndi omwe ali ndi ntchito yodzipatula. Palibe zida zolumikizirana ndi makina panthawi yosinthira. Chifukwa chake, kuwonjezera pa ntchito zomwezo monga ma relay amagetsi, ma relay a solid-state amagwirizananso ndi ma logic circuits, osagwirizana ndi kugwedezeka ndi kugwedezeka kwa makina, ndipo ali ndi malo osatha okhazikitsa. , ali ndi magwiridwe antchito abwino oteteza chinyezi, oteteza mildew komanso oletsa dzimbiri, amagwira ntchito bwino kwambiri popewa kuphulika ndi kuipitsidwa kwa ozoni, mphamvu yolowera yochepa, mphamvu yotsika yowongolera, mphamvu yotsika yowongolera, mphamvu yabwino yogwirizana ndi ma electromagnetic, phokoso lochepa komanso pafupipafupi yogwira ntchito.

Ubwino ndi kuipa kwa ma solid state relay
Choyamba, ubwino wa ma solid state relay
1. Nthawi yayitali yogwira ntchito komanso kudalirika kwakukulu: SSR ilibe zida zamakaniko, ndipo ili ndi zida zolimba kuti zigwire ntchito yolumikizirana. Popeza palibe zida zoyenda, imatha kugwira ntchito m'malo ogwedezeka kwambiri komanso ogwedezeka. Chifukwa cha chilengedwe cha zigawo zomwe zimapanga solid state relay Makhalidwe ake ndi omwe amatsimikizira kukhala ndi moyo wautali komanso kudalirika kwakukulu kwa solid state relay;
2. Kuzindikira kwambiri, mphamvu yotsika yowongolera komanso kugwirizana bwino kwa ma elekitiromagineti: ma solid state relay ali ndi ma voltage ambiri olowera komanso mphamvu yotsika yoyendetsera, ndipo amagwirizana ndi ma logic integrated circuits ambiri opanda ma buffers kapena ma driver;
3. Kusinthana mwachangu: relay ya solid state imagwiritsa ntchito solid state, kotero liwiro la kusinthana likhoza kukhala kuyambira ma millisecond angapo mpaka ma microsecond ochepa;
4. Kusokoneza pang'ono kwa ma electromagnetic: Cholumikizira cha solid state chilibe "coil" yolowera, palibe arcing ndi rebound, motero chimachepetsa kusokoneza kwa ma electromagnetic. Ma AC output solid state relay ambiri ndi switch ya zero-voltage, yomwe imayatsidwa pa zero voltage ndi zero current. Zimazimitsa, kuchepetsa kusokonezeka kwadzidzidzi mu mawonekedwe a current waveform, potero zimachepetsa zotsatira za kusintha kwa transients.
Chachiwiri, kuipa kwa ma solid state relay
1. Kutsika kwa magetsi mu chubu pambuyo pa conduction kumakhala kwakukulu, kutsika kwa magetsi kutsogolo kwa thyristor kapena bi-phase thyristor kumatha kufika 1 ~ 2V, ndipo kuthamanga kwa saturation kwa transistor yamphamvu kwambiri kuli pakati pa 1 ~ 2V. Cholowa chamagetsi choyendetsa ndi chachikulu kuposa kukana kwa kukhudzana kwa makina;
2. Chipangizo cha semiconductor chikazimitsidwa, pakhoza kukhalabe kutuluka kwa ma microamps angapo mpaka ma milliamps angapo, kotero kusiyanitsa kwabwino kwa magetsi sikungatheke;
3. Chifukwa cha kuchepa kwakukulu kwa magetsi a chubu, mphamvu zomwe zimagwiritsidwa ntchito komanso kutentha komwe kumachitika pambuyo pa conduction nazonso ndi zazikulu, kuchuluka kwa ma relay amphamvu kwambiri ndi kwakukulu kwambiri kuposa ma relay amagetsi okhala ndi mphamvu yomweyo, ndipo mtengo wake ndi wokweranso;
4. Makhalidwe a kutentha kwa zigawo zamagetsi ndi mphamvu yoletsa kusokoneza kwa ma circuits amagetsi ndi otsika, ndipo kukana kwa radiation nakonso ndi kochepa. Ngati palibe njira zogwira mtima zomwe zatengedwa, kudalirika kwa ntchito kudzakhala kochepa;
5. Ma relay a solid-state ndi osavuta kugwiritsa ntchito akamadzaza kwambiri, ndipo ayenera kutetezedwa ndi ma fuse othamanga kapena ma RC damping circuits. Katundu wa ma relay a solid-state ndi wogwirizana ndi kutentha kwa mlengalenga. Kutentha kukakwera, mphamvu ya katundu imatsika mofulumira.
