CEFB1-42浪涌保護器的類型和用途

1、雷擊的形成和危害

CEFB1-42過電壓作為電力問題的一種對電力係統的損害十分明顯，導致電力係統的設備故障或者設備損壞。過電壓分為內過電壓和外過電壓，而內過電壓一般對於民用電以及配電係統和設備不會造成危害；外過電壓對於設備的危害比較大，是由空氣中大量放電所導致的，即雷擊作用，必·採取有效措施才能避免其對電子設備的破壞。

2、國內浪涌保護器的現狀和用途

CEFB1-42浪涌保護器主要是對電子設備起過電保護作用，以避免雷擊效應對電子設備和用電設施產生巨大的瞬態電壓而導致過壓損壞。浪涌保護器既能夠防止過電壓又能夠分走浪涌的電流，隨著工業科技的快速發展以及防雷擊等災害的日漸重視，浪涌保護器取得了快速的發展。

3、浪涌保護器的原理和分類

CEFB1-42浪涌保護器的工作原理就是通過限壓或者分流避免電路中過壓現象的發生，主要由氣體放電管、放電間隙、半導體、濾波器及二極管構成。按用途分可以將浪涌保護器分為電源浪涌保護器、電流浪涌保護器以及天饋線浪涌保護器；按工作原理可以分為電壓開關型、限壓型以及組合型。
