Capacitor Load Contactor

CovCJ19C Capacitor Load Contactoryog ib qho khoom siv hluav taws xob tshwj xeeb uas tsim los rau kev ua haujlwm tshwj xeeb ntawm kev ua thiab rhuav cov kab hluav taws xob kom qis -voltage shunt capacitors. Nws yog ib feem tseem ceeb ntawm kev them nyiaj tsis siv neeg siv rau kev kho lub zog reactive. Cov khoom siv tau zoo no yog tsim los siv rau hauv AC lub zog hluav taws xob ua haujlwm ntawm 50Hz nrog cov ntsuas hluav taws xob mus txog 380V, ua kom muaj peev xwm tuav tau qhov loj li 90kvar kom pab txhawb kev txhim kho lub zog zoo. Nws architecture ua raws li kev hloov pauv, lub tsev - thaiv txoj cai. Ib qho tseem ceeb tsim nam yog qhov chaw ntawm peb -path resistor circuit, uas yog mounted saum lub hauv paus ntsiab lus sib dhos. Cov kev sib cuag tseem ceeb ntawm lawv tus kheej yog nteg tawm rationally kom ntseeg tau tias kev ua tau zoo nyob rau hauv ib qho kev thauj khoom zoo. Txhawm rau lav nws cov haujlwm tshwj xeeb thiab kev pabcuam lub neej, lubCapacitor Load Contactoryuav tsum tau siv nyob rau hauv cov nram qab no kev ua hauj lwm thiab installation constraints: a) ambient huab cua kub yuav tsum nyob rau hauv lub cheeb tsam ntawm ib tug qis tshaj ntawm -5℃mus rau ib tug sab sauv txwv ntawm +40 degree, nrog rau qhov nruab nrab tus nqi xam nyob rau hauv 24-teev lub sij hawm tsis tshaj +35 degree. b) Qhov siab ntawm qhov chaw teeb tsa yuav tsum tsis pub tshaj 2000 meters saum toj no hiav txwv theem. c) Txog cov av noo, thaum huab cua kub ntawm +40 degree, qhov txheeb ze av noo ntawm qhov chaw teeb tsa yuav tsum tsis txhob ntau tshaj 50%. Tsis tas li ntawd, qhov nruab nrab qhov nruab nrab qhov nruab nrab ntawm lub hli ntub dej yuav tsum tsis txhob siab tshaj +25 degree, thiab qhov nruab nrab qhov nruab nrab qhov nruab nrab ntawm cov av noo nyob rau lub hli tshwj xeeb yuav tsum nyob qis dua 90%. d) Cov cuab yeej raug ntsuas rau kev ua pa phem 3 ib puag ncig. e) Nws belongs rau installation qeb III. f) Lub tsev yuav tsum tau muab tso rau qhov chaw tseem ceeb ntawm kev co, mechanical shock, lossis kev vibration tsis tuaj. g) Lub contactor lub mounting nto yuav tsum tsis txhob inclined ntau tshaj 5 degrees los ntawm ntsug dav hlau.

Lub hauv paus ntsiab lus ua haujlwm uas ua rau cov khoom siv tau zoo yog piav qhia hauv daim duab 1. Lub schematic saum cov kab dotted sawv cev rau lub capacitor switching circuit, thiab hauv qab no nws yog lub txhab nyiaj thaum lub sij hawm capacitor. Incorporated rau hauv tus tsim yog ib tug resistor switching Circuit Court tsim los ntawm thaum ntxov- ua kev sib cuag nyob rau hauv series nrog resistors. Thaum lub contactor lub electromagnetic coil yog energized, qhov resistor txoj kev kaw ua ntej. Thawj zaug tam sim no ntws los ntawm cov resistors kom them cov capacitors, ib txoj kev uas ua tiav inhibits siab inrush tam sim no txuam nrog capacitor switching. Tom qab qhov kev tswj hwm no ua ntej- nqi, cov neeg sib cuag tseem ceeb nyob ze kom nqa lub nra tas mus li. Ib qho txiaj ntsig tseem ceeb ntawm qhov noCapacitor Load Contactoryog tias nws cov resistor Circuit Court txiav tawm ntawm lub ntsiab Circuit Court thiab rov pib dua thaum lub inrush suppression tiav. Cov yam ntxwv no nquag txo qhov kev pheej hmoo ntawm cov resistors raug puas tsuaj los yog hlawv tawm thaum lub capacitors tom qab txiav tawm ntawm lub voj voog, muab kev tiv thaiv zoo tshaj thiab ua rau txo nqi tag nrho ntawm cov tswv cuab rau kev txhim kho cov khoom siv hluav taws xob.

Saib daim duab 2 rau kev sib txuas hauv Circuit Court thiab cov cim davhlau ya nyob twg ntawm CJ19C hom.

CJ19C-115 contactor muaj ib qho kev sib tiv tauj, muaj nyob rau hauv ob qho tib si; auxiliary contact ob peb ua ke yog qhia nyob rau hauv Table 1. Pab modules yuav muab ntsia tau rau ntawm ob sab ntawm tus contactor kom muaj ntau tus neeg pab sib cuag.

Ob hom auxiliary modules muaj:

LA8-DN11 (ib txwm qhib thiab ib txwm kaw)

LA8-DN20 (ob qho tib si qhib); xaiv los ntawm tus neeg siv thaum xaj.

Appearance thiab Installation Dimensions:

Lub CJ19C-115 contactor tuaj yeem ntsia tau nrog M6 screws thiab xauv lub tshuab ntxhua khaub ncaws, lossis nrog ob lub 35mm mounting ntsia, nrog rau qhov chaw nruab nrab ntawm 105mm ntawm ob txoj hlua. Cov tsos thiab kev teeb tsa qhov ntev ntawm CJ19C-115 yog qhia hauv daim duab 5.
