防雷隔离器以及防雷隔离电路
摘要：
本发明公开了一种防雷隔离器及防雷隔离电路。防雷隔离器包括壳体、隔离器主板、防雷隔离器输入端子A1-A3、防雷用的浪涌保护模块以及连接单元，浪涌保护模块、隔离器主板、均固定在壳体内，防雷隔离器输入端子A1-A3固定在壳体上，浪涌保护模块通过连接单元与隔离器主板电连接，连接单元还与防雷隔离器输入端子A1-A3电连接。防雷隔离电路包括隔离电路、浪涌保护电路以及用于连接所述浪涌保护电路与所述隔离电路三个协调电阻R54、R31、R22。本发明防雷隔离器及防雷隔离电路可消除残压、自检其寿命，更换浪涌保护模块时，不影响隔离器工作，提高了系统的可靠性，同时也降低了成本。
摘要（英）：

The invention discloses a lightning-protection isolator and a lightning-protection isolating circuit. The lightning-protection isolator comprises a shell, an isolator mainboard, lightning-protection isolator input terminals A1-A3, a surge protecting module for lightning protection and a connecting unit, the surge protecting module and the isolator mainboard are fixed in the shell, the lightning-protection isolator input terminals A1-A3 are fixed on the shell, and the surge protecting module is electrically connected with the isolator mainboard through the connecting unit which is electrically connected with the lightning-protection isolator input terminals A1-A3. The lightning-protection isolating circuit comprises an isolating circuit, a surge protecting circuit and three coordinate resistors R54, R31 and R22. By the lightning-protection isolator and the lightning-protection isolating circuit, residual voltage can be eliminated, and service lives of the lightning-protection isolator and the lightning-protection isolating circuit can be detected automatically; when the surge protecting module is replaced, work of the isolator is unaffected, reliability of a system is improved, and cost is lowered.
