Tšebeliso ea transformer ea mofuta o bulehileng e nang le boleng ba ho fetoha

Open-type current transformers for Lisebelisoa tsa IoT. Morero ona oa Marang-rang oa Lintho o hlahisa ts'ebeliso ea li-transformer tsa mofuta o bulehileng mererong ea nchafatso, karolo ea li-transformer tsa mofuta o bulehileng tse nang le li-switches, le melemo ha e bapisoa le li-transformer tse tloaelehileng tsa mofuta o bulehileng, e kopantsoe le tlhahlobo ea linyeoe tsa boenjiniere.

Mantsoe a sehlooho: mokhoa oa ho tsamaisa matla a tlaase a motlakase, ho fetola boleng, mofuta o bulehileng, transformer ea hona joale, kgahlanong le boshodu, Lisebelisoa tsa Inthanete tsa Lintho

Ka phetoho ea likhoele tsa motlakase tsa litoropong le tsa mahaeng indastering ea motlakase ea naha ea heso le ntlafatso e tsoelang pele ea boiketsetso ba lits'ebetso tsa kabo ea matla a tlase., li-transformer tsa mofuta o bulehileng, e le karolo ea bohlokoa ea motlakase lits'ebetsong tsa kabo ea matla a tlase, phetha karolo e ntseng e eketseha ea bohlokoa phetohong ea marang-rang a matla. Ho ntse ho totobala haholoanyane hore e ’nile ea sebelisoa haholo ha ho lekanya, metering, tšireletso ea relay, tlhokomelo ea tsamaiso, tšireletso ea mobu le tlhahlobo e fapaneng ea tsamaiso ea matla.

Leha ho le joalo, ha o kenya li-transformer tsa mofuta o bulehileng oa motlakase o tlase hona joale 'marakeng, maqhama a se ke a tlangwa, ho etsa hore mokokotlo wa tshepe o se koalehe ka botlalo; Li-cores tsa tšepe tse ka holimo le tse tlaase ha lia koaloa, e amang ho nepahala ha transformer kapa ha ho tlhahiso ea hona joale. Transformer ea mofuta o bulehileng e nang le boleng ba phetoho e ka khutlisa boemo bo kaholimo ho sesebelisoa kapa bokamorao, 'me e na le litebello tse pharaletseng tsa ts'ebeliso mererong ea tlhahlobo ea motlakase.

2. Molao-motheo oa ho sebetsa oa transformer ea hona joale

Molao-motheo oa ts'ebetso oa mochine o bulehileng oa motlakase o tlaase o bontšoa ho Setšoantšo 1.

Mokokotlo o ka sehloohong oa transformer ea hona joale e bulehileng e hokahane ka letoto moleng o tlas'a teko. I1 ke mohala oa hona joale, ke hore, motlakase o ka sehloohong oa transformer ea hona joale, 'me N1 ke palo ea liphetoho tse ka sehloohong tsa transformer ea hona joale. I2 ke motlakase oa bobeli oa motlakase oa hona joale, N2 ke palo ea liphetolelo tsa bobeli tsa transformer ea hona joale, 'me Z2e ke tšitiso ea lisebelisoa tsa potoloho ea bobeli le lithapo tse hokahanyang. Ha motlakase oa mantlha o phalla ho tsoa ho terminal ea P1 ea transformer ea hajoale ebe o tsoa ho terminal ea P2, ha Z2e ea bobeli e hokahane, e ipapisitse le molao-motheo oa induction ea electromagnetic, moea oa bobeli oa transformer ea hona joale o na le I2 ea hona joale e phallang ho tloha S1, ho tloha ho Z2e ho ea ho S2, etsa sekgoqetsane se koetsoeng.

Ho tloha ho sena, e ka fumanoa hore hona joale ke I1×N1=I2×N2 boemong bo loketseng, kahoo I1/I2=N1/N2=K, 'me K ke karo-karolelano ea phetoho ea transformer ea hona joale. Leha ho le joalo, kaha mokokotlo oa tšepe oa transformer ea mofuta o bulehileng o khaotsoe, ts'ebetso ea mokokotlo oa tšepe e tla ba matla le ho feta, kahoo sebaka sa sefapano sa mokokotlo oa tšepe oa transformer se tlameha ho eketseha, 'me palo ea ho fetoha ha ampere e tlameha ho eketseha, le I1×N1=I2 ×N2≥100AN.

Holim'a moo, bakeng sa switjha boleng switjha ho transformer, ha buckle ea transformer e sa notleloa hantle kapa casing e robehile ka lebaka la botsofali ba transformer., konopo ea switjha ea hlaha, ka tlwaelo e kwetsweng e ba ka tlwaelo e bulehang, phetiso ya letshwao e fedisitswe, 'me transformer ha e na tlhahiso ea pontšo; Ha buckle ea transformer e tloaelehile, boemo ba switjha ka tloaelo koaloa, 'me transformer e sebetsa ka mokhoa o tloaelehileng.

3. Bula mofuta oa hona joale oa transformer

Li-transformer tsa mofuta o bulehileng li sebelisoa haholo mererong ea kaho ea marang-rang ea litoropo le mahaeng indastering. E tšoauoa ka ho instola tse bonolo, ha ho hlokahale ho tlosa busbar ea mantlha, hape e ka sebetsoa ka motlakase. Leha ho le joalo, li-transformer tsa mofuta o bulehileng oa mofuta o tlase o teng hona joale 'marakeng li na le mefokolo e latelang:

(1) Transformer ea hona joale ea mofuta o bulehileng 'marakeng e ka' na ea se ke ea tiisoa kapa motheo oa tšepe o ka 'na oa se ke oa koaloa nakong ea ho kenya, 'me ho ka' na ha e-ba le kotsi ea hore transformer e oe kapa e khaole nakong ea ts'ebetso;

(2) Haeba sesebelisoa sa hona joale sa mofuta o bulehileng se buloa ka mokhoa oa maiketsetso ka lekhetlo la bobeli ka mor'a ho kenya, ho tla ba le mathata a kang ho se be le pontšo.

Ho shebana le mefokolo e ka holimo, AKH-0.66/Li-transformer tsa hona joale tsa K-SW li ka rarolla mathata a ka holimo. Transformer ena e na le ponahalo e ntle, bonolo ho kenya le tlhokomelo. Joalokaha ho bontšitsoe Figure 2, transformer e na le melemo e latelang:
