TRICONEX 3720 数字输出模块海运船舶航行防雷安全和可能存在的雷电风险：

1.火灾风险

这些风险可能是由于船舶内的电气系统导线或连接开关松动可能产生的火花造成的。此外，设备船舶机舱跳闸前系统过热也可能导致火灾。

2.短路

TRICONEX 3720 数字输出模块设备电气短路是一个危险的安全隐患，短路会造成船舶电路系统的致命损坏，一般的船舶电路都会有安全装置，但是使用不符合标准的SPD浪涌保护器，不能防止瞬时的过载雷电浪涌。这里推荐使用地凯科技智能模块式电源防雷器（100-150kA）SPD-DK-380AC100 浪涌保护器，避雷器。根据行业需要可以定制更大电流浪涌保护的产品。

3.触电风险

船舶接地系统故障，会形成一个导电的系统，这样航行的船只就是一个移动的导体！这会对船上人员造成生命的威胁，有触电的危险。雷电造成的雷击心脏骤停是致命的！

(1)完善船舶防直击雷措施。建议参照GB50057- (2010)R的技术要求，将船舶防雷等级按二类防雷标准进行设计和施工。避雷针保护范围要全覆盖船体。接地引下线应采用屏蔽电缆。

(2)完善等电位连接及屏蔽措施。从室外进入舱内的各种线缆(信号线或电源线)应穿管屏蔽并做好两端接地处理。各种设备外壳及驾驶室门窗她应进行s型等电位连接。

(3)完善电源及电子信息系统电涌保护措施。在船舶电源线路安装三级电源电涌保护器。电涌保护器的标称电流、持续工作电压、残压、安装方式应符合相关规范的要求。对进入机舱的各种信号线，要根据其工作频率、传输速率、工作电压、接口方式、特性阻抗等参数，在信号设备前端安装适配的信号电涌保护器。

(4)建立健全各项安全制度，制订雷击事故发生应急处置预案。同时，船上工作人员应重视对防雷设施的维护:按规定正确使用各种设备，尤其是通信设备，避免遭雷击损坏。雷暴天气船上工作人员应避免在甲板上尤其是桅杆.上作业。船上工作人员必须经过培训并且有能力进行自救，具备处理应急雷击突发事故的能力。

The 3720 TRICONEX is a highly reliable safety controller that provides a complete control and monitoring system. It uses triple fault tolerance technology to ensure that the system can still operate normally in the event of a failure. In addition, the 3720 TRICONEX has flexible configuration options that can be customized to meet different application needs.
TRICONEX 3720 Digital Output Module Marine Vessel navigation Lightning Protection Safety and possible lightning Risks:

1. Fire risk

These risks can be caused by possible sparks from loose electrical system wires or connection switches within the vessel. In addition, overheating of the system before tripping of the engine room of the equipment vessel may also cause a fire.

2. Short Circuit

TRICONEX 3720 digital output module equipment electrical short circuit is a dangerous safety hazard, short circuit can cause fatal damage to the ship circuit system, the general ship circuit will have safety devices, but the use of substandard SPD surge protection, can not prevent instantaneous overload lightning surge. It is recommended to use the smart modular power supply lightning arrester (100-150kA) SPD-DK-380AC100 surge protector and lightning arrester. According to the needs of the industry can be customized larger surge protection products.

3. Risk of electric shock

The failure of the ship’s grounding system will form a conductive system, so that the sailing ship is a moving conductor! This poses a threat to the lives of those on board and a risk of electrocution. Sudden cardiac arrest caused by lightning can be fatal!

(1) Improve ship anti-direct lightning measures. According to the technical requirements of GB50057- (2010)R, the ship lightning protection grade should be designed and constructed according to the second class lightning protection standard. The protection range of the lightning rod should cover the entire hull. The ground lead line should be shielded cable.

(2) Perfect equipotential connection and shielding measures. All kinds of cables (signal cables or power cables) entering the cabin from the outside should be shielded through pipes and grounded at both ends. All kinds of equipment housing and cab doors and Windows should be S-type equipotential connection.

(3) Improve the power supply and electronic information system surge protection measures. Install a three-stage power surge protector on the ship’s power line. The nominal current, continuous working voltage, residual voltage and installation mode of the surge protector shall meet the requirements of the relevant specifications. For all kinds of signal lines entering the engine room, according to their working frequency, transmission rate, working voltage, interface mode, characteristic impedance and other parameters, the adaptive signal surge protector is installed in the front end of the signal equipment.

(4) Establish and improve various safety systems, and formulate emergency response plans for lightning accidents. At the same time, the staff on board should pay attention to the maintenance of lightning protection facilities: according to the regulations, the correct use of various equipment, especially communication equipment, to avoid damage by lightning strikes. During thunderstorms, ship staff should avoid being on deck, especially on masts. Do your homework. Shipboard personnel must be trained and capable of self-rescue, and have the ability to deal with lightning emergencies.
