Mitir korontada: Waa maxay ugu wanaagsan?

Milkiilaha kasta oo hantida waa in loo soo dajiyo qalab gaar ah si loo tixgeliyo biyaha, korontada, gaaska iyo sida D. ah. Haddii Mudanayaasha qalab ah si loo tixgeliyo kulaylka iyo biyaha ayaa dib u dhac ah, rakibo mitirka waa in marka hore la sameeyaa.

Sida loo doorto meter tamarta ah?

Absolutely oo dhan shirkadaha soo saara qalabka sida iyaga siin muddo damaanad in xaddiga lix iyo toban sannadood ah, iyo waxa badan oo sheegay in bedelkiisa soo noqnoqda ayaa loo baahan yahay.

Laakiin marmar dhif ah marka ay timaado in weli wax iibsiga meter cusub, helana oo aan haysan macluumaadka oo dhan ka dhigi karaa doorasho khalad ah. Waa maxay mitir korontada waa ka wanaagsan in ay ku riday? First aad u baahan tahay si ay u bartaan mabda'a mitirka, iyo sidoo kale in ay kala duwan ee model jira.

meter korontada Induction

Waxaa jira laba nooc oo mitir korontada: induction oo elektaroonik ah. Waa kuwee e-mail. counter waa fiican in la isticmaalo, dooran, akhri macluumaadka hoose.

Sidaas daraaddeed, nooca ugu horeysay ee qalabka - si farsamaysan. Dhismaha danab induction ka mid ah counter ambadeen, disc bir ah iyo coil hadda. Sababtoo ah oo duurka ku magnetic taas oo u muuqata ay sabab u tahay xidhiidhka ka mid ah labada gariiradda, disk biraha bilaabaa inuu isku shaandheyn, sida giraangirihiina ku noqnoqosho leh tirooyin muujinaya lacagta bixisay tamarta korontada.

Hayso qalabka sida waa doodista iyo minuses. faa'iidooyinka loo saarin karaa in ay nolosha qiimaha iyo adeega dheer yar, iyo in ay ka biyodiiday ah - qaladka ee akhrinta ah oo ku saabsan 2%. Laakiin joogitaanka muddada dheer ah ee noocan ah ee mitir ee suuqa ku dhsan margin halkii badan oo qalad iyo iyaga ka dhigaa inay arrin ka mid ah iibsada caan ah. Sidaas si ay uga jawaabaan su'aasha ah waxa counter waa ka fiican, ha fikiri nooca labaad ee qalabka.

counter elektarooniga ah

Qalabka elektaroonik ah aasaas ahaan waa kala duwan ka kor ku xusan. Waxaa gebi ahaanba ka maqan wax calaamado ah oo farsamo, iyo hadda waxaa si toos ah bixisey in ka chips iyo semiconductors. chips iyo waxay muujinayaan xaddiga korontada baabbi'iyey, keeno lambarka ku soo dhisay-in scoreboard electronic. The sifooyinka ugu muhiimsan ee wanaagsan ee this mitir - size yar yar, xog dheeraad ah oo sax ah, qaab elektaroonik ah, oo gaabnaa sahlan oo awood u leh si ay u xisaabiso isticmaalka dhowr qorshe canshuur kala duwan. Iyo qiimaha sare iyo nolosha adeeg gaaban waa lagu daro rabin in ay.

mitir korontada Single-waji

Sida laga soo xigtay nooca network si taas oo ay jirto xiriir, qalabka la isticimaalay oo koronto ah kala qaybsan yihiin hal waji oo saddex waji.

mitir wajiga Single ku xiran yihiin hal waji network laba-silig a. load guud ee shabakadda oo ay la socdaan tirada fiilooyin jira arrimo waaweyn. unit xisaabaadka Single-waji loo isticmaalo in kiiska halkaas oo isticmaalka awooda uu ka yar yahay 10 kV. Siinayaa counter ah 220 V.

qalabka saddex waji

counters Kuwani ku xiran yihiin shabakadaha saddex waji, kaasoo noqda cad magacooda. Tan iyo markii aad u baahan tahay tamar badan ay howlgalka, ayaa codsatay in ay dhirta ama gaashaankii guryo dabaq , counters saddex waji awoodda korontada.

Waa kuwee waa ka fiican si loo soo dajiyo guri gaar loo leeyahay? Inta badan gelin, waa hal waji. Waxay la xiran karo iyo in network saddex waji leh, laakiin waa keliya haddii marxalad kasta u baahan doontaa qalab noocan oo kale ah. saddex waji rakibaadda meter cudurdaar u noqon kara oo keliya isticmaalka qalab kasta oo leh shuruudaha tamar sare, tus, qalab alxanka ama wax u eg in. Ugu wax soo saarka ee counter ku soo saarka 380 iyo ka hortagtaa dhismaha ka korontada korodha.

Qoondaynta hoos canshuur ah

On canshuur ah oo waxaa jira mitir tamarta kala duwan. Waa kuwee waa ka wanaagsan?

1. Mid ka mid ah canshuur. Xisaabayaa heerka mid keliya la doortay. Inta badan loo isticmaalo nolol maalmeedka.
2. Laba-canshuur. Waxay kuu ogolaanaysaa inaad tirin tamarta baabbi'iyey laba qorshe canshuur, tusaale ahaan, hal maalin canshuur, habeenkii oo gebi ahaanba kala duwan. Waxaa loo adeegsaday in warshado kala duwan iyo ururada halkaas oo shaqo la qabtay ee labada gelinba.
3. Multi-canshuur. Waxaa xisaabinaya tamarta dhowr canshuuraha si degdeg ah oo ay yaraysaa kharashka.

Qoondaynta nooca tamarta

qalabka Single-waji oo kaliya cabbiro tamarta firfircoon marayay iyaga, iyo saddex waji, laakiin firfircoon, waxa lagu qiyaasaa tamar badan oo Waxyeelo, iyada oo la tixgelinayo jihada socodka. Tani waxay ka caawisaa inay si wanaagsan u badbaadin on waxyaabaha waaweyn.

mitir korontada, kaas oo ka mid ah waa ka wanaagsan?

Si aad u dooratid counter ugu fiican ee aad u baahan tahay in la tixgeliyo qaar ka mid ah xuduudaha ka qalab iyo wax ku saabsan shabakadda bartaan.

1. Si loo go'aamiyo doorashada ee counter ah hal ama laba-waji, waxaad u baahan tahay in la ogaado nooca xoog, halkaas oo aad doonayso in aad saaray miiska. Si arrintan loo sameeyo, kaliya aad u baahan tahay inaad bixiso si ay counter hore fiiro: haddii ay sheegtay in 220 / 230V, markaa waa in aad iibsato hal waji, iyo haddii ay 220 / 380V ama 230 / 400V - wajiga.
2. Maxaa mitir korontada si fiican u adkeysan load ah? Dad badan oo ku mashquulsan yihiin arrintan. In la dhiso hay'adaha caadiga ah waxaa ka shaqeeya at load a ma ka sareeyaa 60A iyo xoogga 15 kw ah. Haddii si lama filaan ah shabakad ka badan tirooyinkan, waxaa lagama maarmaan ah si ay u bartaan qalabka la load a ugu badan ee 100A. Beegyada uu sida caadiga ah waxaa lagu arki karaa on furitaanka dhismayaasha mashiinada.
3. Number of heerarka waa in aad adigu la aqoonsado. Haddii aad bixiso faa'iido dheeraad ah, ka hor inta ku rakibidda qalabka gaar ah by maamulka loo baahan yahay in la caddeeyo haddii ay awoodaan si ay kuu siiyaan waxa ay kala yihiin. Haddii kale, qalabka iibsaday ma ahan mid waxtar leh.
4. Inta aanad sidoo kale waa inay bixiyaan si ay fursad u sii kordhaya dareenka. Inkasta oo uusan saamayn ku lahayn tayada counter shaqada, laakiin waxay adkayn kartaa rakibo. Haddii aad go'aansato in aad ku rakibi miiska guriga la mashiin qaybsan iyo RCD gudaha in hal sanduuq caag (HagerGolf, Fluminense bisha, dulinka ama energy) ama mid ka mid bir SCHRN gaashaan, ka dibna aad u baahan tahay mitir hal ama saddex waji in qaybsan din-tareenka (ma aha oo dhan qalabka ku saabsan din-tareenka modularity soo jireenka ah). In sanduuq caag ah oo isticmaalaya saddex handarraabbadeedii ama shirka rail KMG mitir korontada. Iyo waxa fiican in ay ku riday meter awood ka baxsan dhismaha, qiyaaso iyo unugyada difaaca? Waa BIZ habboon, CB-1 H-9, Schur-8. Ka hor inta aad ku bixisaan doorasho: midkood si ay u iibsadaan counter ee sii kordhaya on din-tareenka ama dushiisa guri. Laakiin haddii aad doorato in aad ku rakibi din-xadiid waxaa weli loo baahan yahay in laga iibsan. Kaasu wuxuu ahaan doonaa rakibo qalabka Electricity in SCHURN nooca gaashaan bir ama SCHRUN.

5. Ayaa sheegay in counter ugu wanaagsan ee uu leeyahay awoodaha kala duwan oo dheeraad ah, sida nalalka, tirin in maqnaanshaha danab ama baahin warbixin si bandhigay. Si kastaba ha ahaatee, kuwaas oo hawlaha waxqabadka ama hufnaanta qalabka saamayn kuma yeelan doono. , Waa in aad Waxay doono ama ma.
6. Absolutely oo dhan, iyada oo aan marka laga reebo, qalabka ka hor inta aadan suuqa, waxaa waajib ah in hubinta gobolka (hufnaan iyo saxsanaanta) Warshadda. Marka xaqiijin guulaha qalabka baasaboorka ku tuntay, oo kiiska - gosplomba. Sidoo kale, baasaboorka waa in ay taariikhda dhaqmaan, iyo shaabaddii laftiisa - Quarter iyo sanadka ah ee imtixaanka. counter kale waa in la shaabadeeyey iyo in la dhiso shirkad tamarta qeybinayay ah in muddo aan ka badnayn laba sano, iyo saddex waji muddada sida waa la soo gaabiyey in muddo hal sano ah. Sidoo kale waxaa lagama maarmaan ah in la xilliyo gaar loo hubiyo saxnimada oo ka mid ah xisaabaha counter iyo waxa la shaqeeya. Taasi waa sababta qalabka sida waa wax-u bareeg mezhproverochny in qalabka la isticimaalay electronic u dhaxeysa toban ilaa lix iyo toban sannadood, tan iyo taariikhda wax soo saarka.
7. Marka aad iibsato qalab in loo xisaabayaa korontada, waa in aad ilaawin in aad eegto fasalka saxnimada. Tilmaamahan kuu ogolaanayaa inaad ogaato qaladka ugu badan in looga hortagi karaa miiska ee xisaabinta. Celcelis ahaan, tirada loogu talagalay dhismayaasha la deggan yahay 2%.

Shirkadaha in soosaarka ee mitir tamarta fiican

Sida laga soo xigtay shirkadda tirooyinka Abarcad rasmi xarunteeduna tahay magaalada Moscow, 2012-kii, in ka badan siddeed milyan oo mitir korontada sameeyey dhulka ee Ruushka, kuwaas oo qayb libaax ee (90%) ay ahaayeen qalabka-hal waji. Waxaa la sheegay in ee ka howgala gudaha inta badan ka bedeli mitir korontada.

Waa kuwee waa ka fiican in la isticmaalo? Waxaa la og yahay in ka badan ¾ ee wax soo saarka oo dhan in Russia ku dhacaa saddex guuto Ruush. ka mid ah walaac "Energomer" (Stavropol), shirkada "Incotex" ah (Moscow) oo haysta "Moscow Plant Instrumentation". Taasoo keentay in meesha Seddex this qaadataa "Energomer" 40% ka mid ah wax soo saarka ee hantida, maxaa yeelay, waxay degeen "Incotex" iyo "Moscow Plant Instrumentation" 29 iyo 7% siday u kala horreeyaan. Qiimaha counters guriga aad uga hooseeya dibada, laakiin farqiga u tayo ma aha mid aad arki karo.

Madaxda suuqa mitir korontada

Si aad u go'aansato waxa u fiican in meel miiska, waxaanu ka fiirsan shirkadahan a faahfaahsan yar:

1. Concern ka Stavropol 'Energomer "leh labo ka mid ah dhirta ma aha oo kaliya in Russia laakiin sidoo kale in wadamada CIS. Waxay ku takhasustay soo saarta tayo sare leh qiyaaso qalabka of dhammaan noocyada tamarta, qiimaha oo kala duwan 13 ilaa 330 unug in lacagta Yurub.
2. "Incotex" - ururka ugu weyn ee qoyska la warshadaha ee Ruushka iyo wixii ka dambeeya. qaaska ah ee shirkadani waa horumarinta iyo ururinta qalabka elektarooniga ah, taas oo ka mid ah mitir korontada iyo cayn kasta.
3. "Moscow instrumentation Plant" (MZIP). Shirkadda Old ku hawlan wax soo saarka ee qalabka la isticimaalay korontada iyo qalabka kala duwan ee radio. Tirada qalabka soo saaray waa mitir korontada hal iyo laba-waji.
