CovCJ19C 3 Ncej Contactor nrog Pab Pawg Sib Txuasyog ib qho tshwj xeeb ib zaug -theem series ntaus ntawv tsim los hloov qis-voltage ib zaug-theem capacitors lossis rau theem- ntse (split) them nyiaj ntawm peb-theem capacitor nyob rau hauv cov khoom siv hluav taws xob tsis siv neeg reactive. Cov khoom siv ntau yam no yog tsim rau AC lub tshuab hluav taws xob nrog lub zaus ntawm 50Hz thiab qhov ntsuas hluav taws xob ua haujlwm txog li 220V, muaj peev xwm ua thiab rhuav tshem cov capacitor loads txog 90kvar kom txhim kho lub zog zoo. Qhov no ib zaug -theem capacitor switching contactor yog ib qho kev txhim kho tsim los ntawm peb lub Hoobkas, raws li tus qauv CJ19C (16C) thawj. Txhawm rau kom ntseeg tau nws txoj haujlwm txhim khu kev qha, lub3 Pole Contactor nrog Pab Pawg Sib Txuasyuav tsum tau ua thiab nruab rau hauv cov kev txwv nram qab no: a) Ambient huab cua kub: qhov siab tshaj qhov txwv yog +40 degree, qhov nruab nrab tus nqi tshaj 24 teev yuav tsum tsis pub tshaj +35 degree, thiab qis dua yog -5℃. b) Qhov siab ntawm qhov chaw teeb tsa yuav tsum tsis pub tshaj 2000m. c) Cov av noo: ntawm qhov chaw teeb tsa, huab cua txheeb ze av noo yuav tsum tsis pub tshaj 50% thaum qhov kub thiab txias yog +40℃. Qhov nruab nrab qhov nruab nrab qhov nruab nrab ntawm lub hli ntub dej tsis tshaj +25 degree, thiab lub hli qhov nruab nrab qhov siab tshaj plaws ntawm cov av noo tsis tshaj 90%. d) Pollution degree: 3. e) Installation qeb: III. f) Kev poob siab thiab kev vibration: Lub contactor yuav tsum tau nruab qhov uas tsis muaj qhov tseem ceeb ntawm kev co, cuam tshuam, lossis kev co. g) Kev teeb tsa: Lub inclination ntawm tus contactor mounting nto txheeb ze rau lub dav hlau ntsug yuav tsum tsis txhob siab tshaj 5 degree.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov khoom no yog qhia hauv daim duab 1. Daim duab kos duab saum toj no cov kab dotted sawv cev rau lub voj voog rau kev hloov cov capacitors, thaum seem hauv qab no qhia txog ib qho -phase capacitor bank. Thaum ntxov- ua kom muaj kev sib cuag, txuas nrog cov khoom siv hluav taws xob, tsim cov resistor hloov hluav taws xob. Thaum lub contactor lub electromagnetic coil yog energized, lub resistor switching circuits kaw ua ntej ntawm lub ntsiab tiv tauj. Tam sim no pib dhau los ntawm cov resistors kom them cov capacitors, ib txheej txheem uas ua tiav inhibits lub capacitor kaw inrush tam sim no. Tom qab ntawd, cov kev sib cuag tseem ceeb nyob ze kom nqa tag nrho cov peev txheej capacitive. Ib qho tseem ceeb tsim txiaj ntsig ntawm qhov no3 Pole Contactor nrog Pab Pawg Sib Txuasyog tias thaum lub luag haujlwm ntawm inrush suppression tiav lawm, lub resistor Circuit Court txiav tawm ntawm lub ntsiab Circuit Court thiab rov pib dua. Qhov kev ua haujlwm ntse no ua rau txo lub sijhawm rau cov resistors puas los ntawm overheating los yog burnout thaum lub sij hawm capacitor disconnection txheej txheem, txhim khu tag nrho durability thiab kev nyab xeeb ntawm koj ib leeg -theem los yog phua-theem them nyiaj system. Kev suav nrog cov neeg pabcuam pabcuam muab kev yooj yim ntxiv rau kev tswj hwm thiab kev taw qhia nyob rau hauv cov phiaj xwm them nyiaj, ua qhov no ua tau zoo thiab txhim khu kev qha hloov kev daws teeb meem.
Internal Connections thiab Terminal Markings
CJ19C Ib leeg-Phase thiab Peb-Phase Y-Type (yuav tsum muaj peb tus contactors) Cov kab hluav taws xob muaj nyob hauv daim duab 2.
CJ19C (Ib leeg-Phase)-80 contactor muaj peb qhov chaw pabcuam, nrog rau ob qhov sib txuas.
Cov kev sib txuas lus sib txuas tau pom nyob rau hauv Table 1. Cov khoom siv sib txuas tuaj yeem ntsia tau rau ntawm ob sab ntawm tus contactor kom muaj cov neeg pab cuam ntau ntxiv.
Muaj ob hom kev pab cuam hu rau:
