Tsawg Voltage Power Supply Reactive Power Compensation Txee Cheebtsam

Raws li qhov tseem ceebTsawg voltage fais fab mov reactive fais fab them nyiaj txee Cheebtsam, CJ19C ib zaug -theem series contactor yog ib qho khoom tshwj xeeb tsim los rau kev hloov qis -voltage single-theem capacitor lossis rau kev faib nyiaj them rau hauv peb lub tsev txhab nyiaj theem -theem capacitor. Nws yog lub hauv paus tseem ceeb hauv cov khoom siv nyiaj tsis siv neeg siv rau kev kho lub zog reactive. Cov khoom tseem ceeb no tsim nyog rau kev sib koom ua ke rau hauv AC lub zog hluav taws xob nrog zaus ntawm 50Hz thiab qhov ntsuas hluav taws xob ua haujlwm txog li 220V, muaj peev xwm ua thiab tawg kev sib txuas mus rau lub capacitor loads txog 90kvar los pab txhawb kev txhim kho lub zog zoo. Qhov no ib zaug -theem capacitor switching contactor yog ib qho kev txhim kho thiab ua kom zoo nkauj tsim los ntawm peb qhov chaw, tsim los ntawm lub hauv paus ntawm tus qauv CJ19C (16C). Los xyuas kom meej seamless kev ua tau zoo thiab compatibility raws li ib tugTsawg voltage fais fab mov reactive fais fab them nyiaj txee Cheebtsam, nws yuav tsum tau siv raws li cov qauv kev ua haujlwm thiab kev teeb tsa hauv qab no: a) Cov huab cua nyob ib puag ncig yuav tsum nyob nruab nrab ntawm qhov txwv qis ntawm -5℃mus rau qhov txwv siab tshaj ntawm +40 degree, nrog rau qhov nruab nrab tus nqi suav dhau 24-teev lub sijhawm tsis tshaj +35℃. b) Qhov siab ntawm lub txee installation qhov chaw yuav tsum tsis pub tshaj 2000m. c) Cov av noo nyob rau hauv lub txee ib puag ncig yuav tsum tau tswj; ntawm huab cua kub ntawm +40 degree, tus txheeb ze av noo yuav tsum tsis txhob ntau tshaj 50%.

Ntxiv mus, qhov nruab nrab qhov nruab nrab qhov nruab nrab qhov nruab nrab ntawm lub hli ntub tshaj plaws yuav tsum tsis txhob siab tshaj +25 degree, thiab lub hli qhov nruab nrab qhov nruab nrab cov av noo siab tshaj plaws yuav tsum nyob qis dua 90%. d) Cov tivthaiv yog npaj rau siv nyob rau hauv ib puag ncig uas cais raws li cov pa phem℃3. e) Nws cov installation qeb yog III. f) Lub contactor yuav tsum tau mounted rau hauv lub txee nyob rau hauv ib txoj hauj lwm uas tsis muaj kev co tseem ceeb, cuam tshuam, los yog kev co. g) Lub mounting nto rau cov khoom no yuav tsum tsis txhob inclined ntau tshaj 5℃los ntawm ntsug. Lub hauv paus ntsiab lus ntawm kev ua haujlwm, qhov tseem ceeb rau kev tsim cov txee, muaj nyob rau hauv daim duab 1. Lub schematic saum toj no cov kab dotted sawv cev rau lub switching Circuit Court, thiab hauv qab no nws yog ib qho -phase capacitor bank. Cov sib txuas sib txuas ntawm cov hluav taws xob hloov hluav taws xob, muaj qhov ua ntej- ua kom muaj kev sib cuag nrog cov resistors, qhib ua ntej thaum coil energization. Txoj kev no tso cai rau cov capacitors kom them los ntawm qhov tam sim no - txwv cov resistors, yog li damping qhov hloov pauv - ntawm inrush tam sim no. Ua raws li qhov no, cov kev sib cuag tseem ceeb ze rau nqa cov capacitive tam sim no. Qhov tseem ceeb durability feature ntawm noTsawg voltage fais fab mov reactive fais fab them nyiaj txee Cheebtsamyog qhov tsis siv neeg disengagement thiab rov pib dua ntawm lub resistor Circuit Court tom qab nws ua tiav nws inrush suppression hauj lwm. Qhov no txo ​​qis txoj hauv kev ntawm cov hluav taws xob hluav taws xob thaum lub sij hawm capacitor disconnection, txhim kho tag nrho cov kev ntseeg siab, kev nyab xeeb, thiab kev pab lub neej ntawm cov khoom nyob rau hauv koj qhov qis -voltage fais fab mov reactive fais fab nyiaj them txee.

CJ19C Ib leeg-Phase thiab Peb-Phase Y-Type (yuav tsum tau peb tus contactors) Cov duab kab hluav taws xob muaj nyob hauv daim duab 2.

CJ19C (Ib leeg-Phase)-43 contactor muaj ob lub chaw pabcuam, nrog peb 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:

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

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

Sab nrauv Dimensions thiab Installation Dimensions

Lub CJ19C (ib zaug-theem)-43 contactor tuaj yeem ntsia tau siv M4 screws thiab xauv lub tshuab ntxhua khaub ncaws, lossis siv 35mm mounting rail.
