Ke kuleana o nā relays moku'āina paʻa
ʻO nā relays solid-state he mau mea hoʻololi pili ʻole me nā ʻano relay e hoʻohana ana i nā mea semiconductor e pani i nā pilina uila kuʻuna e like me nā mea hoʻololi. ʻO ka SSR hoʻokahi-phase kahi mea hana ʻehā-terminal, nona ʻelua mau kikowaena hoʻokele hoʻokomo, ʻelua mau kikowaena hoʻopuka, a ma waena o ka hoʻokomo a me ka hoʻopuka. No ka hoʻokaʻawale optical, ma hope o ka hoʻohui ʻana o ke kikowaena hoʻokomo i kahi hōʻailona DC a pulse paha i kahi waiwai o kēia manawa, hiki ke hoʻololi ʻia ke kikowaena hoʻopuka mai kahi mokuʻāina off i kahi mokuʻāina on. Hiki i ka relay solid state i hoʻolaʻa ʻia ke loaʻa nā hana o ka pale kaapuni pōkole, ka pale overload a me ka pale overheat, a hiki i ka pūʻolo hoʻōla logic hui ke hoʻokō i ka module akamai e pono ai ka mea hoʻohana, hiki ke hoʻohana pololei ʻia i ka ʻōnaehana hoʻokele.
Nā Hiʻohiʻona o nā Relays State Solid
ʻO nā relays solid-state he mau kuapo uila pili ʻole me ka hana hoʻokaʻawale. ʻAʻohe ʻāpana pili mechanical i ke kaʻina hana hoʻololi. No laila, ma waho aʻe o nā hana like me nā relays electromagnetic, kūpono pū nā relays solid-state me nā kaapuni logic, kū i ka haʻalulu a me ka haʻalulu mechanical, a he mau kūlana hoʻonohonoho palena ʻole. , he hana maikaʻi ka pale ʻana i ka makū, ka pale ʻana i ka mildew a me ka anti-corrosion, hana maikaʻi loa i ka pale ʻana i ka pahū a me ka pale ʻana i ka haumia ozone, ka mana hoʻokomo haʻahaʻa, ka ʻike kiʻekiʻe, ka mana hoʻomalu haʻahaʻa, ka hoʻohālikelike electromagnetic maikaʻi, ka walaʻau haʻahaʻa a me ke alapine hana kiʻekiʻe.

Nā pono a me nā hemahema o nā relays moku'āina paʻa
ʻO ka mea mua, nā pono o nā relays moku'āina paʻa
1. Ola lawelawe kiʻekiʻe a me ka hilinaʻi kiʻekiʻe: ʻAʻohe ʻāpana mīkini o SSR, a he mau mea paʻa-moku e hoʻopau i ka hana pili. ʻOiai ʻaʻohe ʻāpana neʻe, hiki iā ia ke hana i nā wahi haʻalulu kiʻekiʻe a me ka haʻalulu. Ma muli o ke ʻano kūlohelohe o nā ʻāpana e hana ana i ka relay mokuʻāina paʻa, hoʻoholo nā ʻano i ke ola lōʻihi a me ka hilinaʻi kiʻekiʻe o ka relay mokuʻāina paʻa;
2. ʻIke kiʻekiʻe, mana hoʻomalu haʻahaʻa a me ka hoʻohālikelike electromagnetic maikaʻi: loaʻa i nā relays mokuʻāina paʻa kahi ākea ākea o ka volta hoʻokomo a me ka mana hoʻokele haʻahaʻa, a kūpono me ka hapa nui o nā kaapuni hoʻohui logic me ka ʻole o nā buffers a i ʻole nā ​​​​mea hoʻokele;
3. Hoʻololi wikiwiki: hoʻohana ka relay moku'āina paʻa i ka moku'āina paʻa, no laila hiki ke wikiwiki ka hoʻololi ʻana mai kekahi mau milliseconds a i kekahi mau microseconds;
4. Ke komo ʻana o ka electromagnetic liʻiliʻi: ʻAʻohe "coil" hoʻokomo o ka relay mokuʻāina paʻa, ʻaʻohe arcing a me ka rebound, no laila e hōʻemi ana i ke komo ʻana o ka electromagnetic. ʻO ka hapa nui o nā relay mokuʻāina paʻa AC output he kuapo zero-voltage, kahi i hoʻā ʻia ma ka zero voltage a me ke au ʻole. e pio, e hōʻemi ana i nā hōʻoki koke i ke ʻano o kēia manawa, no laila e hōʻemi ana i nā hopena o ka hoʻololi ʻana i nā transients.
ʻO ka lua, nā hemahema o nā relays moku'āina paʻa
1. Nui ka hāʻule ʻana o ke anakahi uila o ka paipu ma hope o ke alakaʻi ʻana, hiki i ka hāʻule ʻana o ke anakahi uila i mua o ka thyristor a i ʻole ka thyristor bi-phase ke hiki i ka 1 ~ 2V, a ʻo ke kaomi saturation o ka transistor mana kiʻekiʻe ma waena o 1 ~ 2V. ʻOi aku ka nui o ke kūpuna uila alakaʻi ma mua o ke kū'ē ʻana o ka pilina mechanical;
2. Ma hope o ka pio ʻana o ka hāmeʻa semiconductor, hiki nō ke loaʻa kahi kahe o ke au mai kekahi mau microamps a i kekahi mau milliamps, no laila ʻaʻole hiki ke hoʻokō ʻia ka hoʻokaʻawale uila kūpono;
3. Ma muli o ka hāʻule nui o ke ana uila o ka paipu, nui nō hoʻi ka hoʻohana ʻana i ka mana a me ka hana wela ma hope o ke alakaʻi ʻana, ʻoi aku ka nui o ka nui o nā relays mokuʻāina paʻa kiʻekiʻe ma mua o nā relays electromagnetic o ka mana like, a kiʻekiʻe hoʻi ke kumukūʻai;
4. ʻO nā ʻano mahana o nā ʻāpana uila a me ka hiki ke kūʻē i ke komo ʻana o nā kaapuni uila he haʻahaʻa, a ʻo ke kūʻē ʻana i ka radiation he haʻahaʻa hoʻi. Inā ʻaʻohe hana kūpono e lawe ʻia, e haʻahaʻa ka hilinaʻi o ka hana;
5. He koʻikoʻi loa nā relays solid-state i ka overload, a pono e pale ʻia e nā fuses wikiwiki a i ʻole nā ​​​​kaapuni damping RC. ʻIke maopopo ʻia ka ukana o nā relays solid-state i ka mahana ambient. Ke piʻi ka mahana, e hāʻule koke ka hiki ke ukana.
