Sib Nqus oob khab - dab tsi nws yog ib thiab yuav ua li cas mus cuag

Yuav kom to taub li cas mus cuag ib tug sib nqus oob khab, koj yuav tsum to taub lub hauv paus ntsiab lus ntawm nws cov lag luam. Nws yog yooj yim thiab tag zoo tib yam mus rau ib tug nyob rau hauv uas lub kev khiav hauj lwm tej relay.

Lub ntsiab hauj lwm ntawm lub magnetic oob khab - ib tug haib thaj chaw deb kev twb kev txuas load, uas yuav ua tau yog nyob rau hauv phau ntawv hom los yog nyob rau hauv lub algorithmic ua hauj lwm uas muaj cia installation.

Lub ntsiab Cheebtsam ntawm lub magnetic Actuator yog inductive kauj tsim ib tug sib nqus teb, ib tug thauj tog rau nkoj mechanically ua ke nrog ib tug ntawm cov kev sib cuag pawg, thiab lwm khub hu.

Lub inductor yog muaj nyob rau hauv cov kev tswj Circuit Court, muaj raws ntawm series-kev cob cog rua "Stop" nyees khawm nrog nquag kaw hu thiab lub "Start" feem ntau qhib. Parallel mus rau lub "Start" khawm kom tig rau lwm hu rau khub uas yog kaw ib txhij nrog lub load kev cob cog rua.

Sib Nqus hloov tej hauj lwm raws li nram no: thaum koj nias lub "Start" kaw hluav taws xob Circuit Court, tam sim no kis tau los ntawm lub "Tsis txhob" kaw cov neeg uas cov nyees khawm thiab (vim hais tias lawv yog feem ntau kaw), uas txhais tau tias - nws yog tsis tau nyem rau ntawm no khawm, rau hauv Circuit Court yog tsis tau qhib. Nrog rau cov zaj uas hluav taws xob tam sim no los ntawm ib tug kauj nyob rau hauv nws muaj ib tug sib nqus teb uas attracts lub armature, uas, nyob rau hauv lem, txuas rau cov neeg - ib tug tag nrho ntawm plaub officers. Peb ntawm lawv yog cov yooj yim thiab yog npaj kom muaj xws li ib tug peb-theem ntawm lub payload, xws li ib tug haib electric tsav. Plaub khub kev cob cog rua nyob rau hauv thaum uas tig mus nrog tus txhais khawm, uas muaj peev xwm ces yuav cia mus, thiab tam sim no nyob rau hauv lub Circuit Court yuav ntws los ntawm cov hu.

Nyob rau hauv thiaj li yuav disconnect tus load sufficiently qhib lub solenoid Circuit Court. Rau lub hom phiaj no thiab yog npaj "Stop" khawm, hu pab pawg neeg uas nyob rau hauv lub qub txoj hauj lwm yog raug kaw thiab qhib thaum pressed. Tam sim no txhua yam tshwm sim nyob rau hauv rov qab txiav txim: cov saw hlau yog tu ncua, lub magnetic teb ntawm lub kauj disappears, muaj yog ib tug disconnection ntawm tag nrho cov muaj mob - ob qho tag nrho lub hwj chim thiab restraint. "Nres" khawm, koj yuav tau cia mus - tam sim no nce tswj Circuit Court yuav tsis ua hauj lwm, vim hais tias cov kev sib cuag "Pib" khawm nyob rau hauv lub qub txoj hauj lwm qhib. Tag nrho cov sib nqus contactor yog muab tua.

Feem ntau, cov magnetic contactor kauj yog xam ntawm 220 volts AC nrog ib zaus ntawm 50-60 Hertz. Devices, uas yog siv nyob rau hauv lub tswvyim ntawm magnetic coils los yog transformers, xam thiaj tau tuaj rau lub zaus ntawm 60 Hertz, peb yuav tsum tsis txhob siv - tej zaum lawv yuav yuav puas ntsoog, tab sis lub domestic los yog European magnetic contactor yuav siv tau nyob rau hauv lub tebchaws United States tsis muaj kev txwv.

Raug yuam kev thaum lub sij hawm installation - hloov tswj Circuit Court tsis ntawm theem thiab nruab nrab thiab ntawm theem. Nyob rau hauv rooj plaub no tus bobbin yog flagged 380 volts es tsis txhob 220, thiab nws yog combusted.

Dua li ntawm qhov simplicity ntawm tus dais qhov sib nqus Actuator tsim yog lossi zoo tuaj. Tsim chaw ua hauj lwm, tsim tshiab switching pab kiag li lawm yuav txo suab nrov thaum triggered, thiab txo tau kom tsim thaum lub sij hawm ntawm kev twb kev txuas los yog disconnection ntawm cov neeg ib tug hluav taws xob arc. Qhov no yog tshwj xeeb tshaj yog muaj tseeb ntawm high-voltage contactors, tsim los ua hauj lwm nrog ntau txhiab tus ntawm volts. Yog li, ib leeg Swiss-Swedish lub tuam txhab Asea Brown Boveri Ltd ua Switchgear rau hluav taws xob circuits nyob rau hauv lub lig thib kaum cuaj xyoo pua, nws tau sau loj heev kev nyob rau hauv cov khoom no. Sib Nqus oob khab Abb - tib yam li cov "Yob Royce" ntawm lub tsheb.
