摘要
在 AC-4条件下传统交流接触器的电寿命远小于其机械寿命，主要是由触头分断时产生的电弧对交流接触器触头的烧蚀所致。大量实验表明，触头分断相位不同产生的燃弧能量、燃弧功率不同，即对触头的损害程度也不同。相位控制可以有效减少燃弧能量进而减少触头损耗，所以对交流接触器选相分断控制技术的研究具有重要意义。本文设计了一种交流接触器选相分断控制装置并应用到交流接触器分断特性的研究中。实验表明，该装置能较准确地控制0°到180°的分断相位，选相装置误差小于1°。
Abstract
Under the condition of AC-4, the electrical endurance of a traditional AC contactor is far less than its mechanical endurance, which is mainly caused by the arc erosion generated when the contact is in breaking process. A large number of experiments indicate that different contact breaking phases produce different arc energy and nurning arc power, which cause different extents of damage to the contacts. Since the phase control can effectively reduce arc energy and thus reduce the contact damage, it is significant to the phase selection disjunctiion control technology of AC contactors. The paper designs a breaking phase control device and applies it to the research on AC contactor breaking characteristics. The experiment exposes that the device can relatively control breaking phases precisely between 0° to 180° with errors less than 1°.
