Thermal relay imagwiritsidwa ntchito kwambiri kuti ichulukitse kuteteza mota ya asynchronous. Mfundo yake yogwirira ntchito ndi yakuti pambuyo podutsa muyeso wamakono ndikudutsa muzitsulo zotentha, pepala lachitsulo lawiri limapindika kukankhira njira yoyendetsera kukhudzana, kuti athetse kayendetsedwe ka kayendetsedwe ka galimoto ndikuzindikira kutsekedwa kwa galimoto, ndikuchita nawo mbali Chifukwa cha nthawi yayitali yotenthetsera kutentha komwe kumafunikira pakupindika kwa mbale ya bimmetal, cholumikizira chotenthetsera sichingagwiritsidwe ntchito ngati chitetezo chachifupi, koma ngati chitetezo chochulukira chachitetezo chowonjezera chachitetezo chotumizirana matenthedwe.
Pamene chiwongolero chotenthetsera chimagwiritsidwa ntchito kuti chitetezeke mochulukira, kulumikiza chinthu chotenthetsera ndi mafunde a stator a mota motsatizana, kukhudzana komwe kumakhala kotsekeka kwa relay yotenthetsera kumalumikizidwa mumayendedwe owongolera a koyilo yamagetsi ya AC contactor, ndi chowongolera chamakono chosinthira chimasinthidwa kuti chiwongolero cha herringbone chikhale mtunda woyenera kuchokera ku ndodo yokankhira.Motor ikamagwira ntchito bwino, mphamvu yapano kudzera muchotenthetsera ndiyomwe idavotera. galimoto. Thermal element ikamawotha, chitsulo chapawiri chimapindika pambuyo pakuwotcha, kotero kuti ndodo yokankhira imangolumikizana ndi ndodo ya herringbone, koma singakankhire ndodo ya herringbone. mota imagwira ntchito bwino.
Ngati galimoto zimachulukirachulukira zinthu, panopa mu mapiringidzo ukuwonjezeka, kudzera panopa mu matenthedwe kalawidwe chinthu bimetallic kutentha limatuluka apamwamba, kupinda digiri, kulimbikitsa herringbone lever, herringbone lever kukankha nthawi zambiri kutseka kukhudzana, kupanga kukhudzana anadula ndi kusagwirizana AC. contactor koyilo dera, kupanga contactor kumasulidwa, kudula galimoto mphamvu, galimoto kusiya ndi kutetezedwa.
Mbali zina za relay matenthedwe ndi motere: herringbone lever mkono wakumanzere amapangidwa ndi bimetallic, pamene kutentha yozungulira kusintha, dera waukulu adzatulutsa mapindikidwe ena kupinda, ndiye dzanja lamanzere mu njira yomweyo, kuti mtunda pakati pa herringbone lever. ndipo kukankha ndodo kumakhalabe kosasintha, kuonetsetsa kulondola kwa matenthedwe relay action.Ichi chimatchedwa kutentha chipukuta misozi kanthu.
Screw 8 ndi screw yosinthira yokhala ndi reset yolumikizidwa yomwe nthawi zambiri imatsekeka.Pamene wononga malo ali kumanzere, injini ikadzaza, kukhudzana komwe kumatsekedwa kumachotsedwa, injiniyo ikasiya, kutentha kwa bimetallic sheet kuzizira kumayambiranso. Zolumikizana zomwe zimatsekedwa zimangoyambiranso pakachitika kasupe.Panthawiyi, cholumikizira chotenthetsera chimakhala chokhazikika. ngati galimotoyo yadzaza kwambiri, kukhudzana komwe kumakhala kotsekedwa kwa relay yotenthetsera kumachotsedwa.Zolumikizana zosuntha zidzafika pa malo atsopano kumanja.Kulumikizana kosuntha sikungakhazikitsidwenso injini itazimitsidwa.Butani lokonzanso liyenera kukanikizidwa lisanayambe. Pakali pano, relay yotenthetsera ili m'malo obwezeretsanso pamanja.Ngati kuchuluka kwa mota kuli kolakwika, kuti mupewe kuyambitsanso injini mosavuta, relay yotenthetsera iyenera kutengera Kuti musinthe mawonekedwe a relay yotenthetsera kuchokera pamachitidwe obwezeretsanso pamanja kupita kunjira yokhazikitsiranso yokha, ingopotoza sikona yosinthira bwererani molunjika pamalo oyenera.
