Single-phase wan n-gun meter ni gaw wan n-gun shadawn ai hte lang ai ni a jai lang ai lam hpe hkang zing na matu ahkyak ai arung arai ni rai nga ai. Shanhte a hkrak ai lam hte kam hpa mai ai lam gaw wan n-gun jahpu hpe tara rap ra ai hku dawdan ai lam hte wan n-gun grid bungli galaw ai lam a shim lum lam hpe hkrak hkrak hkra machyi shangun ai.Aten galu-n-gun rawng ai hku bungli galaw lu na matu, meter a prat hpe galu kaba hkra galaw lu na matu, hkrat sum ai lam ni hpe shayawm lu na matu, hpaji masa hte myit sawn sumru ai hku gram lajang ai lam ni hpe galaw ra ai. Ndai laika hta, lang ai ni hte wan n-gun hparan ai magam gun ni hpe shanhte a meter hpe grau kaja hkra gram lajang lu na matu, single-phase wan n-gun meter ni hpe shani shagu gram lajang ai ladat ni, byin chye ai manghkang ni, hparan ladat ni hpe hkrak tsun dan da ai.
Single-Phase wan n-gun meter ni a matu shani shagu gram lajang ai ladat ni
1. Galoi mung san seng ai
Grai na hkra lang ai shaloi, meter case, terminal ni, display ni hta ga nhpu, sau, shing nrai hka lim ai lam ni law law hpawng de wa nna, hti ai lam asan sha byin wa chye ai hte kata na daw ni a katsi ai hpe shapraw kau lu ai. Dai majaw, meter hpe ayan jasan jaseng ra ai (shaning mali hta kalang (sh) semi-shaning shagu jasan jaseng na matu hpaji jaw da ai):
• Case hpe katsi ai, n-gun n rawng ai brush (sh) loi mi katsi ai (non-conductive) n-gun n rawng ai hpun palawng hte katsi katsang hte madun u.
• Case (sh) display hpe n hkra hkra, organic solvents (alcohol (sh) gasoline zawn re ai) shing nrai, n-gun ja ai jasan jaseng ai arung arai ni hpe koi nga u.
• Terminal ni hta oxidation (sh) nhprang wan n-gun rawng ai rai yang, kaja ai hku matut mahkai lu na matu, wan jak (sh) alcohol-based cotton swab hte shim lum ai hku kashin kau ra ai.
2. Terminal ni hpe yu yu ga .
Meter ntsa na n-gun n rawng ai (sh) oxidized terminal ni gaw, n kaja ai hku matut mahkai ai lam, grai katsi ai lam, shim lum lam hpe pyi hkra machyi shangun chye ai. Hkamja lam hpe gram lajang ai hta lawm ra ai:
• Shang wa ai hte pru wa ai terminal ni hpe n-gun ja hkra jep yu nna, ra ai rai yang torque wrench lang nna, masat da ai hku n-gun ja hkra galaw u.
• Terminal ni hpe wan hkru ai-in, oxidation, shing nrai verdigris byin ai kumla ni nga ai kun ngu ai hpe jep yu u. Nga yang, terminal block hpe alawan address (sh) galai kau u.
• Wire ni hpe n hkrat sum ai, n kaba ai, n hkrat sum ai sha, insulation hpe mung n hkra hkra galaw ra ai, shing nrai, short circuit (sh) hka lim mat na hpe koi lu na matu.
3. Magam bungli galaw ai masa hpe yu u
Shani shagu lang ai aten hta, meter a bungli galaw ai masa hpe sadi ra ai, dai hta lawm ai:
• Display Screen: Digital display gaw asan sha rai nna, n lawm ai laika man ni, n htoi tu ai, nsam hpraw ai ni n nga ai hpe yu u.
• Nhtoi Madun ai Masa: Meter nkau mi hta pulse nhtoi (sh) matut mahkai lam madun ai nhtoi nga ai. Flashing frequency hpe yu nna, shingra tara hku galaw ai hte maren sha rai nga ai hpe sadi u.
• N kaja ai nsen ni: N kaja ai hku bungli galaw ai energy meter gaw n kaja ai nsen ni hpe n shapraw ging ai. Humming (sh) discharge nsen ni nga yang, kata na daw langai hkrat sum ai hpe madun nna, alawan sawk sagawn ra ai.
4. grup yin hpe htuk manu hkra galaw lu ai lam hte gram lajang ai lam
Wan n-gun meter ni hpe gaw, garan gachyan ai box (sh) meter box ni hta bang da ai. Shanhte a bungli galaw ai makau grup yin gaw lawu na masa ni hpe hkan sa ra ai:
• Katsi ai shara hte katsi ai shara: Jan a nhtoi htoi tu ai shara, katsi ai shara (50℃jan ), shing nrai, katsi ai shara (relative humidity 85% jan) hta n jung u. Ra ai rai yang makawp maga ladat ni hpe bang u.
• Wan n-gun n-gun hpe makawp maga ai lam: N-gun kaba ai-wan jak ni, transformer ni, n-gun ja ai wan n-gun n-gun rawng ai kaga jak ni hpe tsan tsan tawn da nna, shadawn shadang shut ai lam ni hpe koi gam ra ai.
• Nbung hte katsi ai hpe shapraw kau ai lam: Kata na daw ni a asak hpe hkra machyi shangun chye ai katsi ai lam n byin hkra, n-gun meter grup yin hta nbung hpe atsawm sha shapraw na matu sadi ra ai.
Single-Phase wan n-gun meter ni hpe aten kadun laman shadawn shadang hte jep joi ai lam
1. Aten kadun shadawn shadang
Hkrak ai mungdan madang ni hte maren ("JJG 596-2012 Electronic AC wan n-gun shadawn jak ni a matu jep chyoi ai ladat ni" zawn re ai), langai sha lang ai wan n-gun shadawn jak ni hpe madung hku nna aten kadun laman shadawn shadang galaw ra ai:
•Masha nga ai single-phase meter ni: Madung hku nna 6-8 ning shagu hta hkan nna, n-gun jaw ai calibration (sh) galai shai ai lam hpe galaw ra ai.
•Sut masa (sh) hpaga lam hta lang ai single-phase meters: lang ai lang hte grup yin hta hkan nna, n-gun n law ai aten ladaw (ga shadawn, 3-5 ning) ra na re.
Calibration hta shadawn shadang hkrak ai lam, npawt nhpang n-gun, hte meter hpe mungdan madang hte maren rai hkra chyam dinglik ai lam ni lawm ai.
2. Shut ai lam hpe mu tam ai
Masha langai ngai gaw shi a meter n hkrak ai ngu myit tsang ai rai yang, wan n-gun jaw ai rung kaw nna jep sagawn na matu hpyi shawn mai ai. Shut ai lam byin chye ai lam ni gaw:
• Metering chip (sh) sampling resistor hpe hkra machyi ai zawn re ai aten galu-lang ai majaw, daw ni a asak kaba wa ai.
• Shinggan na n-gun atsam ni, nbung laru hte voltage galai shai ai lam ni gaw, metering a hkrak ai lam hpe hkra machyi shangun chye ai. • Ya na coil hpe short galaw ai (sh) program hpe galai shai ai zawn re ai ni hpe galai shai ai (sh) ahkang n jaw ai sha galai shai ai (tara n shang ai).
Masha law malawng shut ai lam ni hte hparan ladat ni
1. Meter gaw n hti ai (sh) n tara ai hku shadawn nga ai
• Byin mai ai lam ni: Line daw mat ai, current transformer n kaja ai, kata na chip hkrat sum mat ai.
• Hpa baw hparan ladat: Shang wa ai line kaw power nga ai hpe jep yu nna, load gaw normal re ai hpe jep yu u. Shinggan lam ni hpe yeng seng kau ngut ai hpang mung metering n mai galaw ai rai yang, galai na matu (sh) gram lajang na matu wan n-gun jaw ai rung de matut mahkai u.
2. Display gaw n lawm ai (sh) n kaja ai laika ni hpe madun ai
• Byin mai ai lam ni: Power n-gun yawm ai, display hkrat sum ai, matut mahkai module n kaja ai.
• Hpa baw hparan ladat: Power n-gun (galaw madang 57.7V (sh) 220V) hpe jep yu u. Power supply gaw normal rai tim screen gaw n lawm ai rai yang, hpaji rawng ai ni hku nna gram lajang ra ai.
3. Terminal block ni kaw na grai katsi ai (sh) wan hkru mat ai-
• Byin mai ai lam ni: N kaja ai hku matut mahkai ai lam, wire cross-section n kaba ai, grai law hkra lit la ai.
• Hpa baw hparan ladat: Kalang ta wan n-gun hpe dawm kau nna, terminal matut mahkai ai lam ni hpe jep yu nna, ra ai rai yang, wire (sh) terminal ni hpe grau kaba ai cross-section ni hte galai kau ra ai.
Single-phase wan n-gun meter ni hpe gram lajang ai gaw, hkrak hkrak meter galaw lu na matu hte shim lum ai hku jai lang lu na matu ahkyak nga ai. Galoi mung jasan jaseng ai, wiring ni hpe jep yu ai, bungli galaw ai masa hte grup yin hpe hkang zing ai lam ni hpe yu reng ai gaw meter a asak hpe kaja wa galu shangun nna, hkrat sum na masa hpe mung shayawm ya lu ai. Dai hta n-ga, aten dep calibration galaw ai hte n kaja ai lam ni hpe aten dep hparan ai gaw, tara rap ra ai metering hte grid hpe ngang grin hkra galaw ya lu ai. -hpaji ninghkring n re ai ni gaw, n-gun garan ai majaw byin wa chye ai shimlam tsin-yam ni hpe koi lu na matu, yak hkak ai mara ni hkrum katut yang, wan n-gun jaw ai dap (sh) hpaji ninghkring gram lajang ai magam gun ni hpe alawan matut mahkai ra ai.
