Thermal relay inonyanya kushandiswa kuwedzeredza kuchengetedza iyo asynchronous mota.Nheyo yayo yekushanda ndeyekuti mushure mekuremerwa kwazvino kwapfuura nepakati pechinhu chinopisa, simbi yakapetwa kaviri shiti yakakotama kusundira chiito chekufambisa chiitiko chekubata, kuitira kuti ubvise dhizaini yekudzora mota uye kuona kuvharika kwemota, uye kutamba iro basa. Yekudzivirira kwekuremerwa.Kupihwa nguva yakareba yekupisa kupisa kunodiwa panguva yekudziya kwekukotama kwebimmetal plate, iyo thermal relay haigone kushandiswa sepfupi yekudzivirira yedunhu, asi chete seyakawandisa kudzivirira kwekuremedza kuchengetedzwa kwemafuta relay.
Kana iyo thermal relay ichishandiswa kuremedza chengetedza mota, batanidza iyo inopisa chinhu uye stator mhepo yemota munhevedzano, iyo inowanzovharwa yekubata kweiyo thermal relay yakabatana mukudzora dunhu reiyo electromagnetic coil ye AC contactor, uye iyo yekugadzika ikozvino kugadzirisa knob inogadziriswa kuita kuti herringbone lever ive chinhambwe chakakodzera kubva pamudonzvo wekusundira.Kana iyo mota inoshanda zvakajairika, ikozvino kuburikidza neiyo thermal element ndiyo yakatarwa ikozvino yemota.Kana iyo thermal element ichidziya, simbi yakapetwa kaviri inokotama mushure mekupisa, kuitira kuti simbi yekusundidzira inongobatana neherringbone lever, asi haigone kusundira herringbone rod. Iyo inowanzovharwa maconta anovharwa, iyo AC contactor inoramba yakabatikana, uye iyo mota inoshanda zvakajairika.
Kana iyo mota yakawandisa mamiriro, iyo iripo mumhepo inotenderera ichiwedzera, kuburikidza neyazvino mu thermal relay element bimetallic tembiricha inokwira kumusoro, bending degree, kusimudzira herringbone lever, herringbone lever push kazhinji inovhara iyo yekusangana, ita kuti iyo yekubata ibviswe uye bvisa iyo ac. contactor coil circuit, ita kuti contactor isunungurwe, cheka simba remotokari, motokari inomira uye yakachengetedzwa.
Zvimwe zvikamu zve thermal relay ndezvizvi zvinotevera: herringbone lever ruoko rweruboshwe rwakagadzirwa nebimetallic, kana tembiricha yakadzika ikachinja, dunhu guru rinoburitsa kumwe kuchinjika kwekukotama, ipapo ruoko rweruboshwe munzira imwe chete, kuitira kuti chinhambwe chiri pakati peherringbone lever. uye tsvimbo yekusundidzira inoramba isina kuchinjwa, iva nechokwadi chekururama kweiyo thermal relay action.Ichi chiito chinonzi tembiricha muripo chiito.
Screw 8 is a adjusting screw ine kazhinji yakavharwa contact reset.Kana iyo screw position iri kuruboshwe, mushure mekunge mota yakawandisa, iyo inowanzovharwa inovharwa inobviswa, mushure mekunge mota yamira, inopisa relay bimetallic sheet inotonhorera reset. iyo inowanzovharwa macontacts anozogadzirisa otomatiki pasi pechiito chechirimo.Panguva iyi, iyo thermal relay inodzoreredza otomatiki mamiriro.Apo screw inotenderedzwa counterclockwise kune imwe nzvimbo, kana mota yaremerwa, iyo inowanzovharwa yekubatana kwe thermal. relay yabviswa in a manually reset state.Kana iyo motor overload yakanganisa, kuitira kuti udzivise nyore kutanga motokari zvakare, thermal relay inofanira kutora manual reset mode.Kugadzirisa relay relay kubva kune manual reset mode kune automatic reset mode, zviri nyore. screw iyo reset gadziriso sikururu newachi kuenda panzvimbo yakakodzera.
