Joalo ka sesebelisoa sa mantlha sa ho metha tšebeliso ea matla lits'ebetsong tsa motlakase, moralo oa sebopeho sa methara ea motlakase o ama ka kotloloho ho nepahala, ho ts'epahala le boemo ba bohlale ba ona. Limithara tsa sejoale-joale tsa motlakase hangata li na le li-module tse ngata tse sebetsang 'moho ho bokella, ho sebetsa le ho fetisa data ea matla. Sengoliloeng sena se tla qaqisa sebopeho sa mantlha le likarolo tsa bohlokoa tsa metara ea motlakase ho tsoa ponong ea mochini le ea elektroniki.
Sebopeho sa Mechanical Motlakase Meter
Limithara tsa khale tsa motlakase (joalo ka limithara tsa induction) li itšetleha haholo ka molao-motheo oa ho kenya motlakase ho lekanya matla. Sebopeho sa bona sa mantlha se kenyelletsa likarolo tse latelang:
1.Drive Element
Karolo ea koloi e na le coil ea voltage le coil ea hona joale. Coil ea motlakase e kopantsoe ka tsela e tšoanang le mojaro, ha coil ea hona joale e kopantsoe letoto le mojaro. Ha li na le matla, li-coil tsena tse peli li hlahisa matla a khoheli a chenchana, a sebetsang holim'a aluminium turntable, e etsang hore e potoloha.
2.Potoloho Element
Ntho e potolohang haholo-holo e na le aluminium turntable le shaft. Matla a khoheli a hlahisoang ke karolo ea koloi a potoloha aluminium turntable ka lebelo le lekanang le matla a sebelisoang ke mojaro.
3.Braking Element
Brake magnet e hlahisa torque ea braking ka nqa e 'ngoe ea ho potoloha ha turntable, e netefatsa lebelo le tsitsitseng, kahoo tekanyo e nepahetse.
4. Counter
Khaontara e hokahantsoe le shaft e bilikang ka terene ea likoloi. E tlaleha palo ea liphetoho tsa ho daela 'me e fetolela sena hore e be tšebeliso ea matla (hangata ka li-kilowatt-lihora (kWh)).
Mechini ea mechine e bonolo ebile ha e theko e tlaase, empa e na le mefokolo e kang ho nepahala ho fokolang le ho se khone ho buisana ka thōko. Butle-butle li nkeloa sebaka ke limithara tsa elektroniki.
Sebopeho sa Limithara tsa Elektronike
Limithara tsa elektroniki li sebelisa li-circuits tsa dijithale le theknoloji ea microprocessor, e fanang ka tekanyo e phahameng ea tekanyo le ts'ebetso e atolositsoeng. Sebopeho sa bona sa mantlha se kenyelletsa:
1. Lipotoloho tsa Voltage le tsa Hona Joale Sampling
Limithara tsa elektroniki li bokella mats'oao a motlakase le a hona joale ho sebelisoa li-resistor divider kapa li-transformer 'me li a fetole hore e be mats'oao a tlase-, a tlase-a hona joale a loketseng ho sebetsa.
2. Analog-ho{2}}Digital Converter (ADC)
Matshwao a sampuli a analoge a fetolwa ke ADC hore e be matshwao a dijithale bakeng sa microprocessor ho tswela pele ho bala tshebediso ya matla.
3. Microprocessor (MCU)
Microprocessor ke "boko" ba meter ea elektroniki, e ikarabellang bakeng sa ts'ebetso ea data, lipalo tsa matla, polokelo le taolo ea ponts'o. E ka etsa lipalo tse rarahaneng ho feta kamoo ho hlokahalang, joalo ka matla a motlakase le tlhahlobo ea ho feto-fetoha ha motlakase.
4.Bontša Mojule
Limithara tsa motlakase oa elektroniki hangata li sebelisa ponts'o ea kristale ea metsi (LCD) kapa ponts'o ea LED ho bonts'a tlhahisoleseling joalo ka tšebeliso ea matla, voltage, le hajoale. Limithara tse ling tse phahameng- li boetse li tšehetsa khanya e ka morao le{2}}li-line displays.
5.Communication Module
Limithara tse bohlale tsa sejoale-joale li kopanya likhokahano tsa puisano tse kang RS-485, carrier ea lithapo tsa motlakase (PLC), LoRa, le NB-IoT, tse tšehetsang ho baloa ha limithara tse hole, taolo ea mojaro, le taolo ea marang-rang.
6.Setsi sa Memori
Limithara tsa elektroniki li hahile-ka har'a-mokholi o sa fetoheng (joalo ka EEPROM kapa Flash) nako e telele{2}}ea polokelo ea data ea matla, lintlha tsa liketsahalo, le litlhophiso tsa lipeakanyo, ho netefatsa hore data ha e lahlehe ha motlakase o khaoha.
7.Mojule oa Phepelo ea Matla
Limithara tsa motlakase oa elektronike hangata li sebelisa phepelo ea motlakase e thusang (joalo ka transfoma kapa phepelo ea motlakase). Mefuta e meng e ka hula matla ka kotloloho moleng oa tekanyo ho netefatsa ts'ebetso ea mantlha nakong ea ho khaoha ha motlakase.
Likarolo tsa Sebopeho sa Mefuta e Khethehileng ea Limithara tsa Motlakase
1.Prepaid Meters
Ho ipapisitsoe le limithara tsa elektroniki, limithara tsena li kenyelletsa mojule oa puisano oa karete ea IC kapa radio frequency (RF), e lumellang basebelisi ho reka motlakase pele o sebelisoa le ho sebelisa encryption ho thibela bosholu ba motlakase.
2.Multi-Function Meters
Ntle le metering ea mantlha ea matla, limithara tsena li boetse li fana ka tlhahlobo ea harmonic, lipalo-palo tsa tlhokeho, le ho rema lifate ka liphoso, ho li etsa hore li tšoanele basebelisi ba indasteri le ba khoebo.
3.Smart Meters
Smart metres ke mofuta o ntlafalitsoeng oa methara ea elektroniki, o kopanyang theknoloji ea Internet of Things (IoT) ho ts'ehetsa-khokahanyo ea litsela tse peli, karabelo ea theko ea motlakase ea nako ea sebele-, le tsamaiso e ikemetseng ea grid.
Kakaretso
Moralo oa sebopeho sa limithara tsa motlakase o bile teng ka tsoelo-pele ea theknoloji, ho tloha ho tsa mochini ho ea ho tsa elektroniki ho isa ho tse bohlale. Melao-motheo ea bona ea mantlha esale e le metering e nepahetseng, ts'ebetso e tšepahalang, le taolo e bohlale. Nakong e tlang, ka nts'etsopele ea Marang-rang a Matla, limithara tsa motlakase li tla tsoela pele ho kopanya bohlale ba maiketsetso le litlhahlobo tse kholo tsa data, e be li-node tsa bohlokoa ho marang-rang a bohlale. Ho utloisisa sebopeho sa limithara tsa motlakase ha ho thuse feela tlhokomelo le ho rarolla mathata empa hape ho rala motheo oa kaho ea lisebelisoa tse ncha tsa motlakase.
