Kev tiv thaiv muaj nuj nqi ntawm Thermal Relays

Qee cov qauv ntawm thermal relays kuj muaj theem tsis ua haujlwm tiv thaiv kev ua haujlwm.
Cov theem tsis ua hauj lwm tiv thaiv kev ua haujlwm ntawm thermal relay yog muab los ntawm qhov sib txawv amplification mechanism tsim los ntawm sab hauv thiab sab nraud thawb pas nrig. Thaum lub cev muaj zog ua haujlwm ib txwm, qhov tam sim no ntws los ntawm cov khoom siv hluav taws xob ntawm cov thermal relay yog qhov qub, thiab ob qho tib si sab hauv thiab sab nrauv thawb rods txav mus rau qhov tsim nyog. Thaum ib theem ntawm cov khoom siv hluav taws xob raug txiav thiab ua rau ib theem poob, qhov tam sim no ntawm theem yog xoom. Lub bimetallic daim ntawm cov theem ntawd txias thiab rov pib dua, ua rau lub puab tsaig thawb mus rau sab xis. Cov bimetallic daim ntawm lwm yam ob theem yuav khoov vim qhov nce ntawm tam sim no. Nce, ua rau sab nraud thawb pas nrig txav mus rau sab laug. Vim tias qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv, qhov kev sib txuas ib txwm raug thawb kom disconnect nyob rau lub sijhawm luv luv tom qab lub sijhawm tsis ua haujlwm tshwm sim, ua rau AC contactor raug tso tawm, thiab lub cev muaj zog raug kaw thiab nres. Thiab tiv thaiv.
