摘要
电弧故障是引起电气火灾的原因之一,介绍了一种新型智能控制电弧故障断路装置。研究了电弧故障发生原理,开发了故障发生装置和完成了相应的电弧采集工作,并在此基础上提出了电弧故障复合判据。同时针对判断的需要设计了断路装置的硬件结构和软件流程,为低压配电保护系统增添了新的功能。研究结果表明,该装置的研制成功为低压保护电气开辟了新的领域。
Arc fault is always to be the reason why the electrical machine fires. A new type of intelligent control deviceIarc fault circuit interruputer was introduced. On the basis of studying the occurrence of arc fault and the corresponding collection of the arc, a composite criterion of arc fault was brought forward. Aiming at protecting the low-voltage distribution system,the hardware structure anti software processes of circuit device were designed, and new features to protect were added. The results indicate that the successful development of the dcviee has opened up a new area for low voltage electrical protection.
