Izixhobo kuba ngaphandle umthwalo yangoku. shintsha umthwalo

Kuba ukusebenza ekhuselekileyo, kuquka ukulungiswa kunye nokutshintshwa kwezixhobo zombane, ukulungisa yesekethe isabelo phantsi komthwalo, umbane kufuneka kumsindo. Ukwenza kube lula phantsi komthwalo ngenxa kukuvela ye arc zombane ngokuvula abafowunelwa kwefowuni. Inkqubo ukuba ekhuselekileyo, ukusebenzisa izixhobo ezikhethekileyo - umthwalo iswitshi.

Yintoni na le fowuni?

Layisha switsha sisixhobo osetyenziswayo lokuqhawula iqela lwabafowunelwa kwindawo isekethe yombane nge inyathelo mechanical, baxhotyiswa kunye amagumbi arcing. Isixhobo ifakwa kwi ombane aphezulu kunye yokusebenza lombane phantsi amandla ombane ayi-6 no-10 kilovolts. uneswitshi umthwalo isetyenziswa ngokubanzi ukupheliswa kunye omisa sezitishana distribution ombane kwimimandla yasezidolophini neyasemaphandleni, kwakunye ezivenkileni ze amashishini.

Devices for ngemixokelelwane namanzi amancinci

Ngaphandle umthwalo omkhulu iswitshi isetyenziswa ne transmission manual ngaphandle indlela ucimayo le. Oku kusetyenziswa kwiisekethe namanzi ephantsi - ngokuqhelekileyo kwiqela lenjongo zombane lwendawo zasekhaya okanye ofisi. Umzekelo kwezixhobo onjalo iswitshi umthwalo BH-32. Iyilelwe ukuba ukusebenza kwiisekethe 230-400 V kunye current umthwalo we-22 ukuya 100 A. It has polyusatsiyu ezahlukeneyo - 1 ukuya abafowunelwa 4.

device umthwalo switch

Ukuba sicinga ilungiselelo jikelele womatshini, ngokuzimeleyo uhlobo isicelo, i iswitshi umthwalo Autogas ithi isiseko welding-isakhelo, nto leyo emibonweni enamathele insulators eziphakamileyo-ombane disconnector esisigxina ezinjengeetheminali ezintathu zoqhagamshelwano ngokunxulumene ababhexeshi zesigaba intambo. Ezi abafowunelwa ibekwa Chutes arc.

Kwelinye amaziko amathathu ehambelana iqela ezisisigxina, eli qela abafowunelwa ezinokususwa emele abafowunelwa benziwa ka ezimbini iipleyiti, iimela kunye neqela esanelisa arc apha.

Umzekelo kwisixhobo enjalo ikhefu umthwalo tshintshela BHA 10 ukusebenza ngemixokelelwane ukuya ku-10 kV, nosebenzela rated efikelela kwi 630 A. Olu hlobo ezenziwa kwiinguqulelo ezahlukeneyo: nezixhobo zokucima nokuvula earthing (enye okanye amathathu), kunye iifyuzi (okanye ngaphandle kwazo).

izinto Breaking

Yakhiwa iiplastikhi kwaye ziquka yokudibanela esisigxina zigxunyekwe zokubhala engundoqo. Emacaleni kwipleyiti egumbini enyusiweyo izinto ekudaleni igesi.

Ukuze ukucima i arc, ezivele xa kwasa umxokelelwane, ezi ndidi zilandelayo damping esetyenziswa emagumbini echaphazelekayo:

- Autogas;

- avtopnevmatichesky;

- umoya;

- sulphur hexafluoride;

- iziqalelo cleaner.

Umgaqo nokusebenza breakers beesekethe

Xa plate iyunithi iintshengece zokucima uquka i arc egumbini zokucima ize idityaniswe abafowunelwa ezisisigxina engqinelanayo. Okulandelayo eze ambaxa abafowunelwa eziphambili enokususwa kunye ezisisigxina. Ngelo xesha loqhawulo kwi Autogas umthwalo iswitshi disconnects iqela lokuqala engundoqo lwabafowunelwa, yaye kuphela emva kwabo nokukhubeka iimela arc ingcinezelo kunye nabafowunelwa ezisisigxina i arc zokucima gumbi.

Njengoko imveliso ye nezitshetshe arc zokucima egumbini kwasekwa ngalo mzuzu, oko kumo izinto ekudaleni igesi. Secreted yi le mifanekiso igesi kudala egumbini xi ephakamileyo ukuhamba phakathi yakudubula eshukumayo kunye ezifakelwa, leyo ayivuthele arc longitudinally, ukwandisa ukuqina kwayo. Ngenxa yoku, yena uyahamba aphume.

Ke kaloku, malunga ukudibanisa njani iswitshi umthwalo. Le fowuni ifakwe nkqo, apho itsheki sokulungelelanisa ayisosinyanzelo kwaye inqanaba. Ukuba kuyimfuneko, sebenzisa gasket ezifanelekileyo. Ngoxa retaining iibholiti iliso ngokusisigxina inkululeko stroke Peterson iimela egumbini. Emva koko wabeka i drive (ngaphambili okanye emva - ngokuxhomekeke kuyilo). Unxulumaniso kunye iifolokhwe ozimanye iswitshi shaft lever yamacandelo actuator lever. Okukhona ulawulwa insulators, ezo iyalungiswa abafowunelwa yezihlunu. Emva 25 nangaphandle, ukuba bekungekho ezinxaxhileyo abangena yabe egumbini kunye izitenxo kwindlela yokusebenza drive, eqhagamshelwe izinikezeli sigaba iitephu intambo esisigxina kunye namaqela contact eshukumayo.

Types of breakers beesekethe

Ngendlela actuation zezi zixhobo bohlulwa babe ngamaqela amathathu:

1. Lokuqala - iswitshi ngesandla. IRR yabo emfutshane (umthwalo switsha kunye transmission manual).
2. Eyesibini - kunye Autogas spring drive. Bona designated BHA, kwaye ukufakwa kwabo ikhutshwa yi lempumelelo. Kwaye off - drive entwasahlobo cocked.
3. Kwaye uhlobo lwesithathu - kunye drive kwentwasahlobo iifyuzi. Olu hlobo ubizwa ngokuba GNP. peculiarity lwayo amanga neqiniso yokuba isebenze njenge wokukhuselwa short circuit ngokubeka phezu isakhelo womatshini fuse-link nokukhubeka baphelelwe zabo.
   

Yintoni ezahlukeneyo ukusuka iswitshi umthwalo ezenzekelayo?

Esi sixhobo isebenza kuphela kwi wesiqhelo (ebalwa) actuation lwangoku kwaye uvelisa chain scission kwi nemisinga kwisekethe elifutshane. ngobuwena Zenzekelayo na indlela efanayo yokuzahlula (qhawulo) esijikeleza elifutshane. Ukuba ivule phezu imisinga umthwalo switsha kwisekethe elifutshane, izixhobo ezongezelelweyo zokhuseleko. Umzekelo, unxibelelwano fusible, njengoko ngamayelenqe GNP-hlobo.
