Lub luag haujlwm ntawm Low-Voltage Capacitor
Nov 27, 2025| I. Dab tsi yog Tsawg-Voltage Capacitor?
Tsawg-voltage capacitor yog cov cuab yeej siv hauv lub tshuab hluav taws xob los them nyiaj rau lub zog reactive thiab txhim kho lub zog zoo. Raws li International Electrotechnical Commission (IEC) cov qauv, qhov ntsuas hluav taws xob qis ntawm -voltage capacitors feem ntau qis dua 1000 volts (V), thiab lawv lub zog reactive feem ntau qhia hauv kvar (kilovolt-amperes reactive).
II. Tsawg-Voltage Capacitors Ua Haujlwm li cas
Lub luag haujlwm tseem ceeb ntawm qis-voltage capacitor yog khaws cia thiab tso tawm hluav taws xob hluav taws xob, yog li txhim kho lub zog ntawm lub zog hluav taws xob. Thaum inductive loads (xws li motors, transformers, thiab lwm yam) muaj nyob rau hauv lub hwj chim system, lawv tsim ib tug thov rau reactive hwj chim, ua rau ib tug txo nyob rau hauv lub hwj chim yam. Los ntawm kev muab lub zog reactive, qis-voltage capacitors zoo them rau lub zog reactive siv los ntawm inductive loads, yog li txhim kho lub zog thiab txhim kho kev ua haujlwm ntawm kev siv hluav taws xob.
Lub hauv paus ntsiab lus ua haujlwm ntawm qis-voltage capacitor yog qhov yooj yim. Hauv ib lub voj voog, lub capacitor tuaj yeem raug saib raws li lub zog cia khoom. Thaum qhov hluav taws xob siv rau lub capacitor hloov, lub capacitor tsub nqi thiab tawm raws li nws cov nqi capacitance, tsim kom muaj kev sib pauv ntawm cov hluav taws xob hluav taws xob. Cov txheej txheem no them rov qab rau lub zog reactive hauv Circuit Court, yog li txo cov hluav taws xob poob.
