Zero-hla Switching Contactless Switch
Jan 09, 2026| I. Kev txhais ntawm Zero- hla kev hloov pauv
Zero- crossing switching yog hais txog cov txheej txheem ntawm kev txuas lub capacitor ntawm qhov hluav taws xob xoom point thiab txiav nws ntawm qhov xoom tam sim no.
II. Qhov tseem ceeb ntawm Zero- hla Hloov Hloov
1. Vim li cas txuas ntawm qhov voltage xoom point?
Kev sib txuas ntawm qhov ntsuas hluav taws xob xoom tiv thaiv qhov sib txawv ntawm qhov sib txawv lossis qhov sib txawv ntawm lub capacitor thiab Circuit Court, yog li tshem tawm inrush tam sim no thaum hloov. Qhov no zam cov teeb meem tshwm sim los ntawm cov dej ntws tawm, txo cov hluav taws xob poob, ncua kev pab cuam lub neej ntawm cov khoom siv hluav taws xob reactive, thiab txo qhov cuam tshuam rau lwm yam khoom siv hluav taws xob.
2. Yog vim li cas disconnect ntawm lub zero point tam sim no?
Thaum lub sij hawm reactive zog them, capacitors nqa high tam sim no rau ncua sij hawm. Kev txiav tawm ntawm qhov chaw xoom tam sim no tiv thaiv qhov tshwm sim xws li arcing, yog li tshem tawm cov kev phom sij uas yuav tshwm sim los ntawm kev cuam tshuam cov dej ntws siab.
III. Cov cuab yeej siv kom ua tiav Zero- hla Hloov Hloov
1. Hybrid hloov
2. Thyristor(Silicon Tswj Rectifier, SCR)
3. Sib nqus latching hybrid hloov
