3720 TRICONEX是一種高度可靠的安全控制器，能夠提供完整的控制和監(jiān)測系統(tǒng)。它采用了三重容錯技術(shù)，確保在發(fā)生故障時系統(tǒng)仍能夠正常運行。此外，3720 TRICONEX還具有靈活的配置選項，可根據(jù)不同的應用需求進行定制。
TRICONEX 3720 數(shù)字輸出模塊海運船舶航行防雷安全和可能存在的雷電風險：

1.火災風險

這些風險可能是由于船舶內(nèi)的電氣系統(tǒng)導線或連接開關(guān)松動可能產(chǎn)生的火花造成的。此外，設備船舶機艙跳閘前系統(tǒng)過熱也可能導致火災。

2.短路

TRICONEX 3720 數(shù)字輸出模塊設備電氣短路是一個危險的安全隱患，短路會造成船舶電路系統(tǒng)的致命損壞，一般的船舶電路都會有安全裝置，但是使用不符合標準的SPD浪涌保護器，不能防止瞬時的過載雷電浪涌。這里推薦使用地凱科技智能模塊式電源防雷器（100-150kA）SPD-DK-380AC100 浪涌保護器，避雷器。根據(jù)行業(yè)需要可以定制更大電流浪涌保護的產(chǎn)品。

3.觸電風險

船舶接地系統(tǒng)故障，會形成一個導電的系統(tǒng)，這樣航行的船只就是一個移動的導體！這會對船上人員造成生命的威脅，有觸電的危險。雷電造成的雷擊心臟驟停是致命的！

3720

(1)完善船舶防直擊雷措施。建議參照GB50057- (2010)R的技術(shù)要求，將船舶防雷等級按二類防雷標準進行設計和施工。避雷針保護范圍要全覆蓋船體。接地引下線應采用屏蔽電纜。

(2)完善等電位連接及屏蔽措施。從室外進入艙內(nèi)的各種線纜(信號線或電源線)應穿管屏蔽并做好兩端接地處理。各種設備外殼及駕駛室門窗她應進行s型等電位連接。

(3)完善電源及電子信息系統(tǒng)電涌保護措施。在船舶電源線路安裝三級電源電涌保護器。電涌保護器的標稱電流、持續(xù)工作電壓、殘壓、安裝方式應符合相關(guān)規(guī)范的要求。對進入機艙的各種信號線，要根據(jù)其工作頻率、傳輸速率、工作電壓、接口方式、特性阻抗等參數(shù)，在信號設備前端安裝適配的信號電涌保護器。

(4)建立健全各項安全制度，制訂雷擊事故發(fā)生應急處置預案。同時，船上工作人員應重視對防雷設施的維護:按規(guī)定正確使用各種設備，尤其是通信設備，避免遭雷擊損壞。雷暴天氣船上工作人員應避免在甲板上尤其是桅桿.上作業(yè)。船上工作人員必須經(jīng)過培訓并且有能力進行自救，具備處理應急雷擊突發(fā)事故的能力。

3720

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.
