Ọrụ nke relays steeti siri ike
N'ezie, relays steeti siri ike bụ ngwaọrụ mgbanwe na-anaghị emetụ aka nwere njirimara relays nke na-eji ngwaọrụ semiconductor dochie kọntaktị eletriki ọdịnala dị ka ngwaọrụ mgbanwe. SSR nke otu-phase bụ ngwaọrụ na-arụ ọrụ nke anọ, nke nwere ọdụ njikwa ntinye abụọ, ọdụ mmepụta abụọ, na n'etiti ntinye na mmepụta. Maka mwepụ anya, mgbe ọdụ ntinye tinyechara akara DC ma ọ bụ pulse na uru dị ugbu a, enwere ike ịgbanwe ọdụ mmepụta site na steeti na-adịghị mma gaa na steeti na-agba ọkụ. Relays steeti siri ike raara onwe ya nye nwere ike inwe ọrụ nke nchekwa sekit dị mkpụmkpụ, nchebe oke ibu na nchekwa oke ọkụ, na ngwugwu ọgwụgwọ usoro njikọta nwere ike imezu modulu ọgụgụ isi nke onye ọrụ chọrọ, nke enwere ike iji ozugbo na sistemụ njikwa.
Atụmatụ nke Relays Steeti Solid
Ihe ndọghachi azụ siri ike bụ ihe ndọghachi azụ eletrọniki na-anaghị emetụ aka nke nwere ọrụ iche. Enweghị akụkụ kọntaktị mekanikal n'oge usoro mgbanwe. Ya mere, na mgbakwunye na ọrụ ndị yiri ihe ndọghachi azụ eletrọniki, ihe ndọghachi azụ siri ike dakọtara na sekit logic, na-eguzogide mkpọtụ na ujo mekanikal, ma nwee ọnọdụ nrụnye na-akparaghị ókè. , nwere ezigbo mmiri na-eguzogide, arụmọrụ mgbochi mildew na mgbochi corrosion, arụmọrụ dị mma na mgbochi mgbawa na mgbochi mmetọ ozone, ike ntinye dị ala, mmetụta dị elu, ike njikwa dị ala, ezigbo ndakọrịta eletrọniki, obere mkpọtụ na ugboro ọrụ dị elu.

Uru na ọghọm nke relays steeti siri ike
Nke mbụ, uru nke relays steeti siri ike
1. Ndụ ọrụ dị elu na ntụkwasị obi dị elu: SSR enweghị akụkụ igwe, ọ nwekwara ngwaọrụ siri ike iji mezue ọrụ kọntaktị. Ebe ọ bụ na enweghị akụkụ na-agagharị, ọ nwere ike ịrụ ọrụ na gburugburu ebe mkpọtụ na ịma jijiji dị elu. N'ihi ọdịdị nke ihe ndị mejupụtara relay steeti siri ike. Àgwà ndị a na-ekpebi ogologo ndụ na ntụkwasị obi dị elu nke relay steeti siri ike;
2. Nnukwu mmetụta uche, ike njikwa dị ala na ezigbo ndakọrịta elektrọnik: relays steeti siri ike nwere oke voltaji ntinye sara mbara na ike ịnya ụgbọ ala dị ala, ha dakọtara na ọtụtụ sekit agbakwunyere na-enweghị nchekwa ma ọ bụ draịva;
3. Mgbanwe ngwa ngwa: relay steeti siri ike na-eji steeti siri ike, yabụ ọsọ mgbanwe nwere ike ịdị site na milliseconds ole na ole ruo microsekọnds ole na ole;
4. Obere nnyonye anya elektrọnik: nnyonye anya steeti siri ike enweghị "coil" ntinye, enweghị arcing na rebound, si otú a na-ebelata nnyonye anya elektrọnik. Ọtụtụ nnyonye anya steeti siri ike nke AC na-emepụta bụ mgbanwe voltaji efu, nke a na-agbanye na voltaji efu na ọkụ eletrik efu. gbanyụọ, na-ebelata nkwụsịtụ mberede na ụdị ebili mmiri ugbu a, si otú a na-ebelata mmetụta nke ịgbanwe transients.
Nke abụọ, ọghọm dị na relays steeti siri ike
1. Mbelata voltaji nke tube ahụ mgbe emechara conduction buru ibu, mbelata voltaji n'ihu nke thyristor ma ọ bụ thyristor bi-phase nwere ike iru 1~2V, nrụgide saturation nke transistor ike dị elu dịkwa n'etiti 1~2V. Nna nna eletriki conduction dịkwa ukwuu karịa iguzogide kọntaktị nke kọntaktị igwe;
2. Mgbe agbanyụrụ ngwaọrụ semiconductor ahụ, enwere ike ịnwe ọkụ ntapu nke ọtụtụ microamps ruo ọtụtụ milliamps, yabụ enweghị ike nweta ikewapụ eletriki zuru oke;
3. N'ihi nnukwu mbelata voltaji nke tube ahụ, oriri ike na mmepụta okpomọkụ mgbe emechara conduction dịkwa oke ibu, olu nke relays steeti siri ike dị elu buru ibu karịa nke relays electromagnetic nke nwere otu ikike ahụ, ọnụ ahịa ya dịkwa elu;
4. Àgwà okpomọkụ nke ihe ndị e ji eletrọnịkị rụọ na ikike mgbochi mgbochi nke sekit eletrọnịkị adịghị mma, iguzogide radieshọn adịghịkwa mma. Ọ bụrụ na e meeghị ihe dị irè, ntụkwasị obi ọrụ ga-adị ala;
5. Ihe ndọghachi azụ siri ike na-enwe mmetụta dị ukwuu na oke ibu, a ga-echekwa ha site na fuse ngwa ngwa ma ọ bụ sekit RC damping. O doro anya na ibu nke ihe ndọghachi azụ siri ike metụtara okpomọkụ gburugburu. Mgbe okpomọkụ rịrị elu, ikike ibu ga-ada ngwa ngwa.
