Relay thermal - device nangemigaqo yokusebenza

shintsha thermal yi isixhobo sombane ekhusela isithuthi kuyo nayiphi na isixhobo amaxabiso kakhulu obushushu. Xa iimeko ephezulu umthwalo injini yokucakaca nayiphi na indlela kumatshini yombane okanye isixhobo kuyidla imali olongeziweyo lombane. Le amandla kuba amaxesha amaninzi isicelo ye-injini imithetho. Ngenxa yoko, ukucima kombane yenkqubo ngaphakathi yesekethe yombane iqala ukwandisa ngokukhawuleza lobushushu. Kakade ke, kungakhokelela kakuhle yomonakalo kwesi sixhobo. Ukuthintela oku eesekethe zombane ziquka isixhobo ekhethekileyo ozikhethelayo eyenzelwe wean igunya kwenzeka ukuba naziphi na iindlela engxakeko (transients e networks zombane, ingxinano njl njl). Oku ukhusela yunithi ibizwa relay thermal (ngamanye amaxesha uyakwazi ukufumana igama "thermostat" kwi ncwadi). Umsebenzi ophambili we-relay thermal kukugcina indlela yokusebenza ye kwisixhobo kunye nesikhundla sayo okusebenza lulonke.

Le relay thermal unalo ipleyiti ekhethekileyo bimetallic kubume yayo yangaphakathi. Phantsi yesenzo nomthwalo kunye overvoltages kuthungelwano lombane, ipleyiti onjalo uzimisele (likhubazeke), kwaye imeko yaso yesiqhelo has a kumphezulu othe tyaba ngokwaneleyo. Le ipleyiti bimetallic ambathe wahlamba ngaphandle lwabafowunelwa zombane, ngoko ke ngoku nga ngokukhululekileyo kuqukuqela kwisekethe yombane.

Overvoltage nasekukhuliseni ixabiso le yangoku yombane kwisekethe uqalisa ukwandisa ngokukhawuleza lobushushu. Oku kunegalelo ngokushushubeza i element olusisiseko relay thermal - umaleko-ezimbini metal nembasa. Le yokugqibela iqala ukugoba kwaye iphela ukuhamba kwamandla, ekubeni relay thermal yenzelwe ukuba kunqumle umthwalo kunye ombane xa ukulayisha-mbane.

Noko ke, nesiqwenga bimetallic deflects ngokwaneleyo kancinci. Ukuba contact ezinokususwa kwaye inxibelelene ngqo kuyo, izinga aphambuke eliphantsi ukunika ucimayo zisenzeka ngexesha ngokwaphula wesekethe. Ngoko ke, lo isixhobo eyanda inikezelwa kuyilo relay thermal, ebizwa njalo-"zoqhagamshelwano Bouncing." Oku kulandela uluvo lokuba ukhetho gqatso thermal kusekelwe iimpawu zayo ezifana ixesha lokuphendula ixhomekeke ubukhulu ye yangoku yombane.

Ngenxa umsantsa yomsebenzi umatshini ziza kupheliswa. Emva kwexesha elithile (ngokuqhelekileyo isiqingatha seyure - ngeyure) lupholayo ipleyiti kunye yabuyela kwimeko yayo yangaphambili, oko ulibuyele ndzhendzheleko yesekethe yombane. Isixhobo ebuyela kwimeko entsha.

relay thermal ke iintlobo. Egqugqisileyo yexeshana relay (kuba umthwalo kwisigaba esinye) TPH (ukuba umthwalo kwisigaba-mabini), ukuthumela thermal PTT (ngokuba ukucima kombane eqhubekayo kwisiphaluka ontlantlu-ntathu) kunye RTL switch thermal (ukhuselo iinjini zombane nxamnye ukucima kombane elide).
