摘要：低壓斷路器是低壓配電系統的核心部件，低壓斷路器的功能和性能是否正常，直接影響到配電系統的安全，進而影響整體系統的安全性。目前行業內對低壓斷路器脫扣特性影響因素的研究主要針對的是物項本身的設計及實現，但對低壓斷路器在實際試驗驗證過程中，影響脫扣特性的外界因素的研究維度并不是非常全面，因此開展低壓斷路器熱磁脫扣特性影響因素的試驗驗證工作有很大的必要性。本文主要通過分析低壓斷路器工作原理，總結出影響低壓斷路器熱磁脫扣特性的因素，然后通過試驗驗證的方式進行論證，證明分析結論的正確性。

關鍵詞：低壓斷路器；熱磁脫扣特性

Abstract: Low-voltage circuit breaker is the core component of lowvoltage distribution system. Whether the function and performance of low-voltage circuit breaker are normal or not directly affects the safety of distribution system and then affects the safety of the whole system. At present, the research on the influencing factor of low voltage circuit breaker tripping characteristics focuses on design and realization of the items itself, but in the process of low voltage circuit breaker in the actual test, the external factors influencing the tripping characteristics research dimensions is not very comprehensive, so it is necessary carry out the thermal magnetic low-voltage circuit breaker tripping characteristics influence factors of test work. This paper mainly analyzes the working principle of low-voltage circuit breaker, summarizes the factors that affect the characteristics of low-voltage circuit breaker thermo-magnetic trip, and then proves the correctness of the analysis conclusion through experimental verification.

Key words: Low voltage circuit breaker; Thermo-magnetic trip characteristics
