    過載保護器(又稱「電湧保護器」、「突波保護裝置」、「高壓斷路器」)是一種保護裝置,目的是確保電子設備不會因為突然的電流過載(突波)而受損。這種電流過載的情況可能是由雷擊或電氣故障而引起的。過載保護器通常會內置在其他電器中(例如拖板),但亦有作為獨立發售的過載保護器可供選擇。 

    過載保護器是如何運作的? 

    過載保護器的原理是透過阻擋過剩的電壓,並將其引導至地面,從以保護電子設備。當電壓超過預設閾值時,過載保護器就會被觸發並啟動。它們通常作為電源分配單元的一部分使用,有時亦會配備警示燈來預示故障。 

    過載保護器的類型 

    過載保護器的類型可以根據安裝方式、最大浪湧電流、以及所適用的電氣設備而有所分別。例如: 

    • 同軸電纜專用的過載保護器(用於同軸電纜
    • 6類網線專用的過載保護器(用於6類網線)

    如何選購過載保護器? 

    有些過載保護器具有額外的功能,例如過壓保護、短路保護和接地故障指示,可提供額外的安全保護,而且應選擇來自信譽良好品牌的過載保護器。選購過載保護器時可以留意以下幾點: 

    • 額定電流:過載保護器的額定電流應大於要保護的電器的額定功率。例如,如果要保護功率為1000瓦的電器,則應選擇額定電流為16安培的過載保護器。
    • 插座數量:過載保護器通常有多個插座,以滿足多個電器的使用需求。在選擇過載保護器時,應根據實際使用情況選擇合適的插座數量。
    • 附加功能:有些過載保護器具有附加功能,例如過載指示、漏電保護、電湧保護等。在選擇過載保護器時,可以根據自己的需求選擇具有合適附加功能的產品。
