| 摘要: | 本研究透過自行開發之保護裝置可在電氣異常升溫而潛在電氣火災發生前，即可提早發訊通知屋主或管理者，以立即採取應變預防措施；甚至溫度若持續升高達到第二危險點時，即啟動自動斷電反應，以保護電器設備、預防火災發生。經由花線試驗、半斷線試驗、實際電器負載測試；了解電器設備的電源花線於負載時，花線銅質溫度之變化及半斷線不同斷線率與負載處、斷線處之溫度變化。經實驗得知，使用花線之線徑愈小，則銅溫的升溫愈大，代表其危險性愈高。花線在50%半斷線以內，溫控預警保護裝置仍可有效達到預警通報效果。吹風機測試結果，插頭已有發燙及焦味現象，導致插座安全性破壞；表示插座雖在符合法規電流值12A內；但不容忽略插座的PVC材質，若時常在此電流值（高溫）下，將會使其材料劣化，易引起電氣火災。對於消耗功率較大(700W以上)的電器設備，若能使用本溫控預警保護裝置進行監控，並定期檢查與更換劣化之電源插座；以落實事先預防勝於事後補救之防災觀念，必能有效降低電氣火災的發生率。
The study developed an electrical protection device to send an information to the user under abnormal temperature rise, it maybe occur an electrical fire; even if the temperature continues to rise reaching the second danger point , it initiates automatic power-off reaction to protect the electrical equipment to prevent fires.Through flowers line test, semi- break test , the actual electrical load testing ; to load , change the temperature of the spent copper wire and semi- break disconnection rate different from the load, the temperature at the broken understanding of electrical equipment, power flower line Variety.The study found that the floral wire diameter was smaller, the risk of copper temperaturerise was greater, the higher its behalf. Flowers line at 50% or less and a half break, temperature warning protection device can still be effective to achieve the effect of early warning notification. Hairdryer test results, the plug has been hot and burnt phenomenon, leading to a security breach outlet ; outlet , although showing compliance with regulations in the current value 12A; but it can not be ignored socket PVC material, if often in this current value (high temperature ), the will make material deterioration, can lead to electrical fires.For larger power consumption (700W or more) electrical equipment, if we use the temperature warning protection device, and regularly check and replacement of deteriorated power outlet; prior to the implementation of the concept of prevention is better than a pound of cure of disaster prevention, will be able to effectively reduce the incidence of electrical fires. |
