Cov kab hluav taws xob raug puas tsuaj ntau zaus. Txhawm rau tswj lawv txoj haujlwm, cov khoom siv rov qab tau tsim. Yuav siv tus recloser li cas thiab nws yog dab tsi?
Hauv cov ntsiab lus yooj yim, cov khoom rov qab yog cov khoom siv hluav taws xob siab. Lawv muaj kev cuam tshuam loj heev rau kev ua haujlwm ntawm cov khoom siv hluav taws xob, vim tias feem ntau muaj xwm txheej ceev thiab hluav taws xob tawm. Niaj hnub no qhov no yog qhov teeb meem tseem ceeb ntawm lub zog. Tab sis nrog kev siv cov neeg rov qab los, qhov xwm txheej tau hloov pauv. Lawv tau pib muab ntsia rau ntawm cov kab hluav taws xob siv hluav taws xob txhawm rau tswj kev ua haujlwm thiab tiv thaiv kev cuam tshuam hauv kev ua haujlwm ntawm daim phiaj hluav taws xob. Yog tsis muaj lawv, nws yuav nyuaj rau tswj txoj haujlwm ntawm txoj kab ntev.
Tom qab tag nrho, muaj cov chaw zoo li no nyob rau hauv qhov chaw nyuaj mus txog, qhov nyuaj rau ib tus neeg los tswj hwm kev ua haujlwm ntawm tes hauj lwm.
Recloser - yog dab tsi?
Cov no yog cov khoom siv tsis tau. Qhov nthuav yog tias nws yuav siv sij hawm lawv ob peb lub vib nas this los nrhiav thaj chaw uas qhov kev ua tsis tiav tau tshwm sim. Recloser tuaj yeem siv ua lub taub hauhloov ntawm kev faib network thiab cov ntsiab lus. Tsis tas li nrog nws cov kev pab nws dhau los ua kev sib txuas rau lwm tus neeg siv khoom. Nws kuj muaj peev xwm txheeb xyuas qhov yuam kev. Qhov ntawd yog, yog tias muaj teeb meem tshwm sim, nws sai sai nrhiav qhov chaw ntawm kev puas tsuaj thiab thaiv kev ua txhaum ntxiv.

Txhua lub tsev muaj hluav taws xob. Txhua qhov chaw uas muaj hluav taws xob tam sim no yog qhov nyuaj rau kev tswj xyuas yam tsis muaj cov cuab yeej tshwj xeeb. Nrog lub advent ntawm reclosers, qhov teeb meem ntawm kev tswj hluav taws xob tes hauj lwm tau daws. Vim tias nws yog ib qho khoom siv hloov pauv ntse thiab tsis tas yuav tsum tau saib xyuas. Nws tus kheej tswj cov khoom siv hluav taws xob, raws li nws muaj peev xwm ua tau raws li nws txoj haujlwm. Yog li ntawd, xws li ib tug high-voltage Circuit Court breaker ua lub hauv paus rau lub lag luam ntawm lub tis network.
Functions
Lub hom phiaj tseem ceeb tshaj plaws ntawm tus neeg rov qab los yog tiv thaiv cov kab hluav taws xob los ntawm kev sib tsoo. Vim tias qee zaum muaj xwm txheej tshwm sim thaum qhov kev siv ntawm cov khoom siv tam sim no nce, uas yog, cov kab yog overloaded. Ib tug recloser pab tiv thaiv cov txheej txheem no. Nws tswj kev tes hauj lwm. Thaum muaj overload tshwm sim, lub tshuab hluav taws xob hluav taws xob hloov pauv tau qhib. Tom qab tsim kev ua haujlwm, AC Circuit Court raug qhib. Cov haujlwm zoo li no tau muab tso rau hauv cov khoom siv hluav taws xob no txij thaum pib. Yog li ntawd, tus recloser ua hauj lwm nyob rau hauv raws li tsim ib theem zuj zus ntawm cycles. Ntxiv nrog rau lub luag haujlwm tseem ceeb, lub cuab yeej ua haujlwm ntxiv, tsis muaj qhov tseem ceeb. Cov no suav nrog:
- ua tiav ntawm kev hloov pauv tam sim hauv lub network faib;
- tawm qhov xwm txheej ceev hauv hom tsis siv neeg;
- tig rau txoj kab hluav taws xob tau txais;
- txiav txim siab thaj chaw puas;
- kho dua tshiab ntawm cov khoom siv tam sim no hauv thaj chaw ua haujlwm hauv hom qub;
- sau cov ntaub ntawv hais txog hom kev ua haujlwm ntawm cov phiaj xwm hluav taws xob, lawv cov xwm txheej;
- kev sib tham nrog lub kaw lus telematics.
Ntse
Lub ntsiab lus tseem ceeb uas lub cuab yeej ua nws txoj haujlwm yog lub tshuab nqus tsev vacuum. Nws yog qhov xav tau txhawm rau txiav txim siab sai sai rau qhov chaw luv luv tau tshwm sim txhawm rau txhawm rau txhim kho kev ua haujlwm kub ntxhov ntawm daim phiaj hluav taws xob. Recloser yog dab tsi? Qhov no yog ib qho cuab yeej siv rau kev teeb tsa sab nraum zoov. Cov cuab yeej zoo li no muaj cov yam ntxwv uas paub qhov txawv ntawm lwm yam khoom siv. Cov no suav nrog:
- compact;
- easy to install;
- tsis xav tau cov ntsiab lus tshwj xeeb thiab laj kab;
- cov khoom siv zoo li no tsis tas yuav muab kev pabcuam;
- ua haujlwm tiav lawm.
Qhov no yog qhov tseem ceeb hauv cov cheeb tsam uas nyuaj mus txog, uas tso cai rau koj los kho cov khoom siv hluav taws xob tom qab muaj kev sib tsoo hauv ntu ntawm daim phiaj hluav taws xob. Yog tias nws tsis tuaj yeem tsim cov khoom siv hluav taws xob, cov lus qhia yuav raug xa mus rau tus neeg teb xov tooj. Raws li cov khoom siv hluav taws xob thiab cov tshuab hluav taws xob, cov khoom siv rov qab tuaj yeem muab piv rau lub tshuab hluav taws xob hluav taws xob, uas feem ntau yog ntsia rau hauv qhov nkag ntawm tsev. Lawv tsuas yog txawv ntawm lub zog. Kev khiav hauj lwm voltage yog nyob rau hauvNtau yam ntawm 6 mus rau 35 kV.
Daim ntawv thov
Cov khoom siv no ua rau lub zog hluav taws xob "tsim" raws li lawv ua rau txhua qhov kev ua. Lawv tuaj yeem cais thaj chaw tsis ua haujlwm, thaum ua haujlwm ntawm lwm qhov chaw yuav tsis raug tso tseg. Thaum muaj xwm txheej, xws li cov cuab yeej tam sim ntawd hloov cov neeg siv khoom mus rau lwm qhov chaw siv hluav taws xob, txawm tias muaj kab tawg tshwm sim lossis txhawb kev poob. Recloser ua rau lub zog muab kev ntseeg siab.
Kev tsim cov cuab yeej xws li lub tshuab hluav taws xob siab yog ua los ntawm cov tuam txhab tshwj xeeb hauv kev siv tshuab hluav taws xob faib khoom.
Kwv yees li kaum xyoo dhau los cov hluav taws xob hluav taws xob twb tau siv hauv peb lub tebchaws. Tab sis lawv tsis tau zoo li lawv tam sim no. Yav dhau los, kom haum rau lawv, nws yog ib qho tsim nyog los txhim kho cov peev thiab cov vaj tse modular. Thaum lub tshuab nqus tsev pib siv, cov khoom siv rov qab los ua me me. Raws li qhov tshwm sim, lawv tus nqi tau txo qis.
Nrog kev siv cov cuab yeej tshiab thiab thev naus laus zis, nws tuaj yeem nthuav dav lub peev xwm ntawm cov neeg rov qab, vim lawv tsis tau ua yav dhau los nrog cov haujlwm tsis siv neeg.
Hnub no high-voltage circuit breakers yog tsim los ntawm cov tuam txhab hauv qab no:
- "Tavrida Electric" (Russia).
- Nulec Industries (Australia).
- Wipp&Burn (England).
Cov tuam txhab no koom nrog kev tsim cov khoom siv tsis siv neeg tshwj xeeb.
NyiajDevices
Tus nqi rov qab yog dab tsi? Tus nqi zoo rau cov khoom siv tau tsim los ntawm Lavxias lub tuam txhab Tavrida Electric. Tus nqi yog los ntawm 100,000 mus rau 500,000 rubles. Nws tag nrho yog nyob ntawm qhov xav tau ntawm tus neeg yuav khoom thiab cov yam ntxwv kev. Lawv tsim cov cuab yeej zoo uas xav tau thoob plaws ntiaj teb.
Yog li, tus rov qab kaw yog cov cuab yeej ua kom tsis muaj kev cuam tshuam ntawm kev sib txuas hluav taws xob. Yog tsis muaj cov cuab yeej zoo li no, lawv txoj haujlwm yuav tsis muaj zog.
Yog li ntawd, lawv tsuas yog tsim nyog nyob rau hauv ntau qhov chaw kom tsis txhob muaj xwm txheej tshwm sim hauv kev ua haujlwm ntawm cov kab hluav taws xob. Yog li ntawd, tam sim no nws tau paub meej tias qhov rov qab los yog dab tsi thiab yog vim li cas nws thiaj li muaj nuj nqis heev, ntsia hauv ntau qhov chaw.
