交换机在使用中经常会遇到意外的电压瞬变和浪涌，从而导致内部电子器件的损坏。电压的瞬变和浪涌无处不在，电网、雷击、爆破，就连人在地毯上行走都会产生上万伏的静电感应电压，这些，都是变频器控制端口和通信端口的隐形危害源。因此，为了提高交换机的可靠性就必须对电压瞬变和浪涌采取防护措施。

在作为局域网的主要连接设备，以太网交换机成为应用普及最快的网络设备之一。针对以太网口的浪涌防护，硕凯电子给出如下解决方案：

方案说明及注意事项

1、此方案为以太网交换机千兆以太网口过压保护方案。

2、可以通过IEC61000-4-5标准波形Surge测试及IEC41000-4-2标准波形Discharge测试。

该方案中采用硕凯电子的压敏电阻SC1812-90CSMD和瞬态电压抑制器阵列SLVU2.8-8。参数如下：

一、SC1812-90CSMD

主要优势：1、容值低（<1pf）,有助于保持信号完整性，并将数据丢失率降至最低。；2、体积小，通流量大，满足IEC61000-4-5：10/700US 6KV/150A；1.2/50US&8/20US 2KV/1KA测试要求。测试记录如下：

二、SLVU2.8-8

主要优势：1、具有低电容，有助于保持信号完整性，并将数据丢失率降至最低。2、满足IEC 61000-4-2的最高标准（CONTACT DISCHARGE :8KV；AIR DISCHARGE:15KV），在安装和使用期间为设备提供最大的可靠性。测试记录如下：

硕凯电子是专业的防雷元器件生产商，防护方案设计专家，所有元器件都具有相关UL证书，REACH/ROHS有害物质检测证书，性能稳定可靠。欢迎通过世强选型测试。

【应用】RJ45以太网接口的雷击保护方案

户外以太网容易遭受雷击，雷击浪涌产生的过电压和过电流会损坏以太网电磁兼容平衡，因此做好RJ45以太网接口的雷击保护方案十分必要。使用硕凯电子的GDT和TVS可以设计出符合802.11电气标准、满足IEC61000-4-5和GBT17626.5等浪涌测试标准以及IEC61000-4-2和GBT17626.2等静电测试标准的防护方案。

【应用】国产压敏电阻14D561K用于LED路灯，通流量可达6KA

由于LED灯具有节能、响应时间短、使用寿命长、可直接替换传统灯等优点，所以LED灯的应用越来越广泛，现如今LED路灯也是随处可见。本篇主要讲述硕凯电子14D561K压敏电阻在LED路灯的应用，具有大通流量雷电在电源线路上产生感应浪涌，这个浪涌的能量会在电线上产生一个突波，即浪涌波，浪涌就是通过这样的感应方式进行传输的。
