Power system ni hta n-gun lang ai lam hpe shadawn na matu core device langai hku nna, wan n-gun meter a hkrang masa gaw shi a shadawn shadang hkrak ai lam, kam hpa mai ai lam, hpaji madang ni hpe hkrak hkrak hkra machyi shangun ai. Dai ni na aten na wan n-gun meter ni hta, n-gun atsam hte seng ai shiga ni hpe shinggyin la na, galaw na, htawt sit na matu, bungli galaw ai module law law lawm ai. Ndai laika hta, wan n-gun meter a madung hkrang hte ahkyak ai arung arai ni hpe, jak hte electronic hku nna, hkrak tup tsun dan na re.
Hpaji masa hku nna wan n-gun shadawn ai
Htunghking jak hte galaw ai wan n-gun shadawn jak ni (induction meter zawn re ai ni) gaw n-gun hpe shadawn na matu madung hku nna wan n-gun shadawn ai wan n-gun shadawn ai npawt tara hpe madung tawn ai. Shanhte a core structure hta lawu na daw ni lawm ai:
1.Drive daw
Dai drive element hta voltage coil hte n-gun coil lawm ai. Voltage coil hpe load hte parallel hku matut da nna, current coil hpe gaw load hte series hku matut da ai. Ndai coil lahkawng hpe n-gun jaw ai shaloi, galai shai ai magnetic field hpe shabyin ya nna, dai gaw aluminum turntable ntsa hta bungli galaw nna, dai hpe shinggrup shangun ai.
2.Galaw ai Element
Dai shinggrup ai element gaw madung hku nna aluminum shinggrup ai table hte shaft langai lawm ai. Drive element kaw na pru wa ai magnetic field gaw, aluminum turntable hpe, n-gun lang ai n-gun hte maren, lawan ai hku shinggrup ya ai.
3.Braking daw
Brake magnet gaw, turntable a shingjawng ai lam hte nhtan shai ai maga de braking torque hpe shapraw ya ai majaw, ngang grin ai lawan ai lam hpe lu la nna, shadawn shadang hpe hkrak hkra galaw lu ai.
4. hti ai
Dai counter hpe gear train hku nna shinggrup ai shaft hte matut da ai. Dai gaw dial a shingjawng ai lam hpe ka matsing da nna, dai hpe n-gun jai lang ai lam de galai shai kau ai (galaw madang hku nna kilowatt-hours (kWh) hku nna).
Mechanical meter ni gaw asan sha rai nna manu n dan ai raitim, hkrak ai lam n law ai, tsan tsan kaw nna matut mahkai n lu ai zawn re ai shadawn sharam lam ni hpe hkrum sha nga ai. Dai ni hpe kalang ta electronic meter ni hte galai shai wa nga ai.
Electronic Meter ni a hkrang masa
Electronic meter ni gaw digital circuit hte microprocessor hpaji hpe jai lang nna, shadawn shadang hpe grau hkrak hkra galaw lu ai hte bungli galaw ai lam hpe grau jat wa shangun ai. Shanhte a madung hkrang masa hta:
1. Voltage hte ya aten hpe sample hkam la ai lam
Electronic meter ni gaw, hkrak tup ai resistor divider (sh) transformer ni hpe lang nna, n-gun hte n-gun hpe shinggyin la nna, n-gun n law ai, n-gun n law ai-n-gun hpe galaw na matu htuk manu ai hku galai shai kau ya ai.
2. Analog-de-de Digital galai shai ai jak (ADC)
Sample la ai analog signal ni hpe ADC hku nna digital signal ni de galai shai kau nna, n-gun lang ai lam hpe grau nna sawn la lu na matu, Microprocessor a matu galaw ai.
3. Microprocessor (MCU)
Microprocessor gaw electronic meter a "brain" rai nna, shiga ni hpe gram lajang ai, n-gun hpe sawn la ai, shinggyin tawn ai, madun dan ai lam ni hpe hkang ai lit nga ai. Shi gaw ra ai hku grau sawng ai jahpan ni hpe galaw lu ai, power factor hte voltage galai shai ai lam hpe yu reng ai zawn re ai ni hpe galaw lu ai.
4.Module hpe madun u
Electronic wan n-gun shadawn ai jak ni gaw, n-gun lang ai lam, wan n-gun, wan n-gun zawn re ai shiga ni hpe madun na matu, liquid crystal display (LCD) shing nrai LED display hpe lang ma ai. Nkau high-end meter ni gaw shingdu nhtoi hte-line law law hpe mung madi shadaw ya ai.
5.Matut mahkai lam Module
Dai ni na aten na hpaji rawng ai meter ni gaw RS-485, wan n-gun line htaw ai (PLC), LoRa, hte NB-IoT zawn re ai matut mahkai lam ni hpe hpawng de da nna, tsan tsan kaw nna meter hti ai, lit hpe hkang ai, grid hpe hkang ai lam ni hpe madi shadaw ya ai.
6.Myit dum ai daw
Electronic meter ni hta -n-htum n-wai ai memory (EEPROM (sh) Flash zawn re ai) hta n-gun atsam hte seng ai shiga ni hpe aten galu -hkap la lu na matu, mabyin masa ni hpe ka da ai laika buk ni, hte gram lajang ai lam ni hpe n-gun n-gun shayawm ai aten hta shiga ni n mat mat hkra galaw da ai.
7.N-gun jaw ai Module
Electronic wan n-gun meter ni gaw, n-gun jaw ai wan n-gun (transformer (sh) galai shai ai wan n-gun zawn re ai) hpe lang ma ai. Model nkau mi gaw wan n-gun yawm ai aten hta madung bungli galaw lu na matu shadawn shadang line kaw na wan hpe hkrak sha shaw la mai ai.
Wan n-gun meter ni a laksan hkrang masa ni
1.Shawng jaw da ai Meter ni
Electronic meter ni hpe madung tawn nna, ndai meter ni hta IC card (sh) radio frequency (RF) matut mahkai module hpe bang da ai majaw, wan n lang shi yang wan n-gun mari la mai ai hte wan n-gun lagut ni hpe pat shingdang na matu encryption hpe lang mai ai.
2.Lam law law-Magam Bungli Meter ni
Basic energy metering hta n-ga, ndai meter ni gaw harmonic analysis, ra kadawn ai lam ni hpe jahpan galaw ai, mara ni hpe sawk sagawn ai lam ni hpe mung galaw ya ai majaw, hpaga lam hte hpaga lam hta jai lang ai ni a matu htuk manu ai.
3.Hpaji rawng ai Meter ni
Smart meter ni gaw, electronic meter ni a gram lajang da ai version langai rai nna, Internet of Things (IoT) hpaji masa hpe hpawng de da nna, -lam lahkawng hku matut mahkai lam hpe madi shadaw ya ai, aten dep-wan manu hpe htai ya ai lam, grid hpe tinang hkrai hparan ya ai lam ni hpe madi shadaw ya ai.
Gadun dawk
Wan n-gun meter ni a hkrang masa gaw hpaji masa rawt jat wa ai hte maren rawt jat wa ai, jak hte galaw ai kaw nna electronic kaw nna smart meter ni du hkra rai nga ai. Shanhte a madung tara ni gaw galoi mung hkrak ai metering, kam hpa mai ai bungli galaw ai lam, hpaji rawng ai hku hparan ai lam ni rai nga ai. Htawm hpang de, Energy Internet hpe gyin shalat wa ai hte maren, wan n-gun meter ni gaw, shinggyim hpaji masa hte big data analytics ni hpe grau nna hpaw shalawm nna, smart grid hta ahkyak ai shara ni tai wa na re. Wan n-gun meter ni a hkrang hpe chye na ai gaw, gram lajang ai lam hte manghkang ni hpe hparan na matu loi ai sha n-ga, wan n-gun n-gun nnan ni hpe gawgap na matu npawt nhpang hpe mung gawgap ya lu ai.
