Unipolar tshuab: apparatus, kev yam ntxwv thiab nta ntawm kev twb kev txuas

Circuit Court breaker - ib tug switching ntaus ntawv, cov conductive pub hluav taws xob tam sim no thiab puv tawm lub hwj chim nyob rau hauv excess ntawm lub nominal tus nqi. Nws yog siv rau kev tiv thaiv tiv thaiv overload hluav taws xob circuits. Ib leeg-ncej automatic tiv thaiv tsuas yog ib qho hlau.

Tus ntaus ntawv thiab hauv paus ntsiab lus ntawm cov lag luam

Lub ntsiab yam ntxwv ntawm tus tes hloov qhov yog nominal thiab shutdown ceev. Unipolar tshuab ua hauj lwm los ntawm ob mechanisms: ib thermal thiab electromagnetic txawv tebchaws unit. Tus thawj disables rau hauv Circuit Court nyob rau hauv cov kev tshwm sim ntawm ib tug muaj zog load ntawm kev txiav txim rau ib tug ntev lub sij hawm, thiab lub thib ob - instantly, thaum ib tug luv luv-Circuit Court.

Thermal tiv thaiv ntaus ntawv yog ib tug bimetal phaj. Thaum tam sim no kis tau los ntawm nws saum toj no lub siab tshaj plaws, nws maj mam heats thiab khoov rau ob sab, thawb lub zog, lub kaw-off tshuab. Tom qab txias lub phaj rov qab mus rau hauv qhov chaw, thiab tus tes hloov qhov yog dua npaj txhij rau lub lag luam. Yuav kom nkag mus rau hauv lub lag luam, txuas manually.

Lub electromagnetic ntaus ntawv muaj ib tug kauj nyob hauv tus tub ntxhais. Thaum dhau los ntawm lub luv luv-Circuit Court tam sim no tshwm sim winding electromagnetic teb conveying mandrel, uas disables lub tshuab. Wherein lub hwj chim hu yog qhib, de-energizing Circuit Court. Thaum lawv kis tau los ntawm ib tug loj tam sim no, ib tug arc. Nws ntog rau hauv qhov arc chamber, qhov twg thaum uas tig mus hlau paib. Nrog lawv pab, arc so li thiab disintegrates.

Lub tshuab kuj siv tau raws li ib tug mus los ntawm rotating cov phau ntawv tswj qib.

Cov kev siv ntawm ib tug ib leeg-ncej Circuit Court breaker

Thaiv nyob rau hauv lub chav tsev faib mus rau hauv ob peb pawg. Txuas ib zaug xwb-ncej tshuab yog ua nyob rau hauv cov kis ntawm cov theem neeg xyuas pib. Nws yog muab tso rau hauv DIN rail, thiab nyob rau hauv nws lub jig hwj chim hlau yog tso. Shielded hlau yog kev cob cog rua rau lub sab clamp. Yog hais tias cov nyob ntawm tej yog nias los ntawm screws, lawv yuav tsum tau nruj me ntsis kev rau siab.

Feem ntau, lub sab sauv terminals ntawm ib leeg-ncej machines muaj kev cob cog rau lub hwj huam mov los ntawm ib zuag, thiab los ntawm lub qis thaiv ua nyob rau hauv pab pawg. Koj yuav teev ntau backup pab kiag li lawm.

npav

Circuit Court tej fais fab muaj ib tug txheej txheem daim ntawv lo, uas yog nyeem los ntawm sab saum toj mus rau nram qab.

Qhov tseem ceeb npaj rau lub twj paj nruag vaj tse nws yooj yim tsis:

• trademark - EKF;
• serial tooj - VA47-29;
• yam ntxwv "C" thiab cov nyob tam sim no mus rau lub automatic ib leeg-ncej - 25A;
• nyob mov voltage - 230/415 V;
• nyiaj pab ntau tshaj pub tawm luv luv Circuit Court currents ntawm - 4500 A;
• 3 - tam sim no tsis pub tshaj hauv chav kawm ntawv.

Los ntawm hom, koj yeej paub lub chaw tsim tshuaj paus. Machine nws yog advisable rau xaiv los ntawm zoo-paub hom: Legrand, Abb, IEK, EKF, thiab lwm tus neeg.

Npe duab rau lub tshuab 230/415 B txhais tau tias tus ntaus ntawv yuav khiav lag luam nyob rau hauv ib-theem thiab peb-theem tes hauj lwm. Feem ntau ntawm cov tsheb nyob rau hauv lub tsev neeg thaiv muaj no muaj peev xwm.

Nyob tam sim no - yog tus nqi tam sim no uas lub tshuab yuav tsis ua hauj lwm rau ib tug ntev lub sij hawm. Thaum nws yog nce los ntawm 13%, nws yuav tig tawm tom qab ib teev. Qhov ntau dua tus nqi ntawm ntev-ntws tam sim no, tus ceev lub lag luam. Lub hom phiaj tseem ceeb ntawm lub tshuab - mus tiv thaiv kom txhob overheating ntawm xov thaum txuas lub load. Nws yog ib qho tseem ceeb tias cov pub neeg xyuas pib tam sim no yog loj denomination tshuab, tsis vice versa.

Lub sij hawm-tam sim no cov yam ntxwv ntawm "C" txhais tau tias lub triggering tawm ntawm ob mechanisms tshwm sim tom qab fivefold kom cov nyob tam sim no. Nws yog tsim rau illumination thiab feem ntau cov khoom siv. Yog hais tias lub tshuab yog muaj nqis tus nkag mus rau qhov no yam ntxwv, nws yuav tsum tau ntsia rau lub tshuab nrog lub ntsiab yam ntxwv ntawm lub tswv yim "B" nyob rau hauv lub tiaj vaj huam sib luag. Qhov no txhais tau tias rau tag nrho cov so tib yam ntxwv nws yuav ua hauj lwm sai. Ces koj tsis tau khiav mus rau lub qhov rooj nkag, thiab muaj xws li tsis siv neeg muaj. Kom xaiv ntaus nrog ib tug haum xeeb ceem muab yam selectivity ntawm dawm taw.

Maximum permissible tripping tam sim no qhia tau hais tias nws cov nqi siab tshaj plaws uas lub tshuab yog muaj peev xwm mus kaw cia yam tsawg ib zaug.

Number of tug

Yog hais tias koj xaiv ib zaug xwb-ncej los yog ob-ncej tshuab, nws yog ib qho tseem ceeb rau, qhov twg rau nruab nws. Nyob rau nkag mus rau lub chav tsev lub ntsiab vaj huam sib luag yuav tsum tau ntsia bipole. Qhov no yuav tso cai rau nti disconnect tus xov nyob rau hauv tsev thaum lub sij hawm kho thaum mus tua cov theem uas nruab nrab. Thaum cov hlau 2 yuav mounted tshuab nrog ib tug hluas ncej nkag tau rau hauv lub tsev. Nyob rau hauv lub xub ntiag ntawm lub grounding neeg xyuas pib muab introductory bipolar tshuab.

Nyob rau txhua ceg ntawm lub tsev network yog kev cob cog rua ib leeg-ncej tshuab nrog lub RCD.

Yog hais tias ib tug chav tsev yog powered los ntawm ib tug peb-theem Circuit Court yuav tsum tau ntsia ntawm lub ntsiab tswv yim plaub-ncej tshuab.

Tsis Siv Neeg ib-ncej: nqi

Ib leeg-ncej automatic cheaper ntawm lwm tus neeg nyob rau hauv lub lineup nrog ib tug loj tus naj npawb ntawm tug. Domestic khoom yuav yuav rau 40-50 rubles., Thiab mas hom yog twb 150-200 rubles. Nws yog ib qho tseem ceeb los mus xaiv tus pab kiag li lawm nyob rau hauv cov kev sib raug zoo zoo-nqe, es cov neeg uas yog cheaper.

Yuam kev nyob hauv Xaiv ib lub tshuab

Xaiv tej fais fab, cia cov neeg siv ib tug xov tooj ntawm tsis.

1. Coj los ntawm tag nrho cov zog noj es tsis txhob nyob ntawm tej los tiv thaiv tiv thaiv overload. Txhim kho ib tug haib tshuab rau cov uas qaug zog thaiv ua rau nws overheating. Nws yog ib qho tseem ceeb rau khaws cov ntaus ntawv tshaj tus ntoo khaub lig seem ntawm cov hlau.
2. Feem ntau muab cov tib machines rau tag nrho cov kab, uas yog vim li cas ib txhia ntawm lawv yog overloaded. Rau nyob yuav tsum tau muaj kev tiv thaiv ntawm 25 A, thiab rau teeb pom kev zoo - 16 A. Tus kab ua rau lub chav nres tsheb, yuav ua tau ntau loaded nrog haib hwj chim cov cuab yeej. Ntawm no nws yog advisable rau nruab rau hauv lub tshuab ntawm 32 A.
3. Tsis txhob xaiv machine rau tus nqi. Zoo dua yuav khoom uas nto moo hom, qhov twg zoo yog guaranteed.

xaus

Yuav kom raug xaiv ib leeg-ncej tshuab yuav tsum to taub lub code rau lub vaj tse los ntawm pem hauv ntej sab. ntaus yam ntxwv raug xaiv nyob ntawm seb lub hom kev cob cog rua load thiab hlau ntoo khaub lig seem.
