Thermal relay inonyanya kushandiswa kuwedzeredza kuchengetedza iyo asynchronous mota. Nheyo yekushanda kwayo ndeyekuti mushure mekuremerwa kwazvino kwapfuura nepakati pechinhu chinopisa, simbi yakapetwa kaviri pepa yakakotama kusundira chiitiko chekufambisa chiitiko chekubata, kuitira kuti ubvise dhizaini yekudzora mota uye kuona kuvharika kwemota, uye kutamba iro basa. Kudzivirirwa kwekuremerwa.Kupihwa nguva yakareba yekutamisa kupisa inodikanwa panguva yekudziya kwekukotama kwebimmetal plate, iyo thermal relay haigone kushandiswa sepfupi yekudzivirira yedunhu, asi chete seyakawandisa kudzivirira kwekudzivirira kwekudzivirira 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 inogadzirisa knob inogadziriswa kuti iite herringbone lever chinhambwe chakakodzera kubva kutsvimbo yekusundidzira.Kana iyo mota inoshanda zvakajairika, ikozvino kuburikidza neiyo thermal element ndiyo yakatarwa ikozvino ye mota. 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 kwechiito chekupisa relay.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. iwo anowanzo kuvharika macontacts anozozvigadzika otomatiki pasi pechiito chechirimo.Panguva ino, iyo thermal relay inodzoreredza otomatiki mamiriro.Kana screw inotenderedzwa counterclockwise kune imwe nzvimbo, kana mota yaremerwa, iyo inowanzovharwa yeiyo thermal relay inodzimwa.Iyo inofambisa maconta ichasvika kune imwe chiyero chinzvimbo kurudyi.Kubata kunofamba hakugone kugadziriswa mushure mekunge mota yadzimwa.Bhatani reset rinofanira kudzvanywa pamberi. Panguva ino, thermal relay iri mune manually reset state.Kana iyo motor overload yakanganisa, kuitira kuti udzivise kutanga injini zvakare, thermal relay inofanira kutora Manual reset mode.Kugadzirisa iyo thermal relay kubva kune manual reset modhi kuenda kune otomatiki reset modhi, ingo jikisa iyo reset yekugadziridza sikururu wachi kuenda panzvimbo yakakodzera.
