Lub luag haujlwm ntawm cov khoom siv hauv xeev khov kho
Cov relays khov kho yog cov khoom siv hloov pauv tsis sib cuag nrog cov yam ntxwv relay uas siv cov khoom siv semiconductor los hloov cov khoom siv hluav taws xob ib txwm muaj ua cov khoom siv hloov pauv. Ib-theem SSR yog plaub-qhov kawg khoom siv nquag, uas muaj ob lub qhov kawg tswj hwm, ob lub qhov kawg tso zis, thiab ntawm qhov nkag thiab tso zis. Rau kev rho tawm qhov muag pom, tom qab lub qhov kawg tso zis ntxiv DC lossis lub teeb liab pulse rau qee qhov tam sim no, lub qhov kawg tso zis tuaj yeem hloov pauv los ntawm lub xeev tawm mus rau lub xeev qhib. Lub relay khov kho tshwj xeeb tuaj yeem muaj cov haujlwm ntawm kev tiv thaiv luv luv, kev tiv thaiv overload thiab kev tiv thaiv overheat, thiab pob khoom siv kho kom zoo tuaj yeem ua tiav cov module ntse uas tus neeg siv xav tau, uas tuaj yeem siv ncaj qha hauv lub kaw lus tswj hwm.
Cov yam ntxwv ntawm Cov Khoom Siv Hluav Taws Xob
Cov relays khov kho yog cov hloov hluav taws xob tsis sib cuag nrog kev ua haujlwm cais tawm. Tsis muaj cov khoom sib cuag thaum lub sijhawm hloov pauv. Yog li ntawd, ntxiv rau cov haujlwm zoo ib yam li cov relays hluav taws xob, cov relays khov kho kuj sib xws nrog cov voj voog logic, tiv taus kev co thiab kev poob siab, thiab muaj qhov chaw teeb tsa tsis txwv. , muaj kev ua tau zoo tiv thaiv dej noo, tiv taus pwm thiab tiv thaiv xeb, ua tau zoo heev hauv kev tiv thaiv kev tawg thiab kev ua qias tuaj ntawm ozone, lub zog nkag qis, kev nkag siab siab, lub zog tswj qis, kev sib raug zoo electromagnetic zoo, suab nrov qis thiab zaus ua haujlwm siab.

Cov txiaj ntsig thiab qhov tsis zoo ntawm cov khoom siv hauv xeev khov kho
Ua ntej, qhov zoo ntawm cov khoom siv hauv xeev khov kho
1. Lub neej ua haujlwm siab thiab kev ntseeg siab siab: SSR tsis muaj cov khoom siv kho tshuab, thiab muaj cov khoom siv khov kho kom ua tiav qhov kev sib cuag. Vim tias tsis muaj cov khoom txav mus los, nws tuaj yeem ua haujlwm hauv qhov chaw poob siab thiab kev co siab. Vim yog qhov xwm txheej ntawm cov khoom uas ua rau lub xeev khov kho relay Cov yam ntxwv txiav txim siab lub neej ntev thiab kev ntseeg siab siab ntawm lub xeev khov kho relay;
2. Kev rhiab heev, lub zog tswj qis thiab kev sib raug zoo ntawm lub zog hluav taws xob: cov relays khov kho muaj qhov dav dav ntawm qhov hluav taws xob thiab lub zog tsav tsheb qis, thiab sib xws nrog feem ntau cov logic integrated circuits yam tsis muaj buffers lossis drivers;
3. Kev hloov pauv sai: lub xeev khov kho relay siv lub xeev khov kho, yog li qhov hloov pauv ceev tuaj yeem yog los ntawm ob peb milliseconds mus rau ob peb microseconds;
4. Kev cuam tshuam me me ntawm electromagnetic: Lub relay solid state tsis muaj input "coil", tsis muaj arcing thiab rebound, yog li txo qhov cuam tshuam electromagnetic. Feem ntau AC output solid state relays yog lub qhov hloov xoom-voltage, uas tig rau ntawm xoom voltage thiab xoom tam sim no. tua, txo qhov cuam tshuam tam sim ntawd hauv cov waveform tam sim no, yog li txo cov teebmeem ntawm kev hloov transients.
Qhov thib ob, qhov tsis zoo ntawm cov khoom siv hauv xeev khov kho
1. Qhov poob hluav taws xob ntawm lub raj tom qab kev sib txuas lus yog loj, qhov poob hluav taws xob pem hauv ntej ntawm thyristor lossis bi-phase thyristor tuaj yeem ncav cuag 1 ~ 2V, thiab qhov siab ntawm lub transistor muaj zog siab yog nruab nrab ntawm 1 ~ 2V. Tus poj koob yawm txwv hluav taws xob conduction kuj tseem loj dua qhov tiv taus ntawm kev sib cuag ntawm cov khoom siv kho tshuab;
2. Tom qab lub cuab yeej semiconductor raug kaw, tseem yuav muaj qhov xau hluav taws xob ntawm ntau lub microamps mus rau ntau lub milliamps, yog li ntawd kev rho tawm hluav taws xob zoo tagnrho tsis tuaj yeem ua tiav;
3. Vim yog qhov hluav taws xob loj poob ntawm lub raj, kev siv hluav taws xob thiab kev tsim cua sov tom qab kev sib txuas lus kuj loj, qhov ntim ntawm cov khoom siv hluav taws xob siab dua li ntawm cov hluav taws xob electromagnetic relays ntawm tib lub peev xwm, thiab tus nqi kuj siab;
4. Cov yam ntxwv kub ntawm cov khoom siv hluav taws xob thiab lub peev xwm tiv thaiv kev cuam tshuam ntawm cov hluav taws xob tsis zoo, thiab kev tiv thaiv hluav taws xob kuj tsis zoo. Yog tias tsis muaj kev ntsuas zoo, kev ntseeg siab ua haujlwm yuav qis;
5. Cov relays solid-state muaj kev nkag siab zoo rau kev thauj khoom ntau dhau, thiab yuav tsum tau tiv thaiv los ntawm cov fuses ceev lossis RC damping circuits. Lub nra hnyav ntawm cov relays solid-state yog qhov tseeb cuam tshuam nrog qhov kub thiab txias. Thaum qhov kub nce siab, lub peev xwm thauj khoom yuav poob sai sai.
