談漏電保護器的選用、正確的接線方法及安裝中注意事項
摘要：漏電保護器是一種常用的具有安全保護功能的電器，本文介紹了如何正確選型、安裝。
關鍵詞：漏電保護器&安裝方法&確保功能
0. 前言
目前我國工業與民用低壓配電系統中，一般均采用接地和接零保護，也就是我們通常所說的TT和TN接地系統。 這兩種系統對供電安全保護起到了一定的作用， 但由于TT和TN系統本身存在一定的缺陷和不足，在實際運行中仍有某些不安全因素，安裝漏電保護器能彌補TT和TN系統的不足，是防止電擊事故的有效措施之一，也是防止漏電引起電氣火災和電氣設備損壞事故的技術措施， 可以進一步提高供電的安全可靠性。因此，漏電保護器在低壓配電系統中被廣泛地采用。

0. Foreword
At present China's industrial and civil low voltage distribution system, generally used to protect ground and then zero, that is what we usually TT and TN grounding system. Both systems supply security played a role, but TT and TN system itself has some flaws and shortcomings, in practice there are still some insecurity run, earth leakage protection devices can make up for TT and TN drawback of the system is to prevent electrical shock one of the effective measures is to prevent electrical fires and electrical leakage caused by the accident damage to equipment technology, we can further improve the safety and reliability of electricity supply. Therefore, the leakage protective device in low power distribution system has been widely adopted.
