STH-40 Series Thermal Overload Relay

Lub cev muaj zog

Kev tiv thaiv lub cev muaj zog: lub luag haujlwm tseem ceeb ntawm lub thermal sib tshooj yog los tiv thaiv lub cev muaj zog los ntawm kev puas tsuaj dhau. Thaum lub cev muaj zog dhau lawm, Thermal ntau dhau Relay yuav txiav tawm ntawm lub zog mov nyob rau lub sijhawm los tiv thaiv lub cev muaj hluav taws xob vim tias overheating.

Kev tiv thaiv ntawm cov kab hluav taws xob: Ntxiv rau kev tiv thaiv lub cev muaj zog, lub thermal sib faib relay tseem tuaj yeem tiv thaiv cov kab hluav taws xob. Thaum lub cev muaj zog dhau lawm, nws tam sim no yuav nce ntxiv, uas yuav ua rau muaj kev kub ntxhov thiab yaj ntawm cov hluav taws xob kab. Los ntawm kev kuaj pom qhov hloov tam sim no, lub thermal sib luag txiav txim seb lub zog hluav taws xob puas dhau thiab txiav tawm lub zog hluav taws xob yog tias tsim nyog.

Txhim kho kev nyab xeeb ntawm lub zog hluav taws xob: thermal tshaj tawm cov kev puas tsuaj ntawm lub cev muaj zog thiab kev txo cov zog ntawm lub zog.

Lub ntsiab cai ntawm kev ua haujlwm

Lub hauv paus ntsiab lus ntawm lub thermal sib tshooj yog tsuas yog raws li cov khoom siv thermal tam sim no thiab ntsuas kub lub zog ntawm lub bimetal. Thaum muaj ntau tshaj tshwm sim hauv lub cev muaj zog, cov nce ntxiv, ua rau muaj ntau lub tshav kub kom tsim tawm hauv cov cua sov ntawm lub thermal sib tshooj. Cov cua sov no pauv mus rau bimetal, uas khoov thaum ua kom sov vim tias nws yog ua los ntawm ob alloys nrog qhov sib txawv ntawm cov coeffientions. Thaum lub bimetal khoov rau qee yam, nws yuav ua rau lub tshuab hluav taws xob, uas nyeg yuav tsav cov neeg hu thiab txiav tawm lub zog ntawm lub cev muaj zog.

Cov tau txais daim ntawv thov

Thermal sib tshooj feem ntau yog siv nyob rau hauv cov voj voog nrog AC 50Hz, ntsuas kev tiv thaiv ntawm peb-theem ua pob rau peb-theem AC motors. Nws kuj tseem siv tau los ua ib qho oob khab nrog tus neeg hu ua account adjected muab kev tiv thaiv kom muaj kev tiv thaiv rau lub cev muaj zog.

Khoom nta

Cov qauv yooj yim: Qhov thermal sib tshooj feem ntau tau txais ib qho qauv txheej txheem yooj yim, ua kom yooj yim rau nruab thiab siv.

Tag nrho cov kev tiv thaiv: Ntxiv rau qhov pib kev tiv thaiv muaj nuj nqi ntau, nws tseem muaj kev tiv thaiv theem kev tiv thaiv thiab kev them nyiaj kub.

Tus nqi qis: piv nrog lwm cov kev tiv thaiv muaj zog, tus nqi ntawm thermal overload muaj tsawg, uas txo tus nqi yuav khoom.

Kev ua haujlwm nyob ruaj khov ua haujlwm: vim tias nws tau bimetal raws li lub ntsiab lus rhiab, nws txoj kev ua haujlwm yog ruaj khov thiab ntseeg tau.
