TRICONEX 3720 數(shù)字輸出模塊海運(yùn)船舶航行防雷安全和可能存在的雷電風(fēng)險(xiǎn)：

1.火災(zāi)風(fēng)險(xiǎn)

這些風(fēng)險(xiǎn)可能是由于船舶內(nèi)的電氣系統(tǒng)導(dǎo)線或連接開(kāi)關(guān)松動(dòng)可能產(chǎn)生的火花造成的。此外，設(shè)備船舶機(jī)艙跳閘前系統(tǒng)過(guò)熱也可能導(dǎo)致火災(zāi)。

2.短路

TRICONEX 3720 數(shù)字輸出模塊設(shè)備電氣短路是一個(gè)危險(xiǎn)的安全隱患，短路會(huì)造成船舶電路系統(tǒng)的致命損壞，一般的船舶電路都會(huì)有安全裝置，但是使用不符合標(biāo)準(zhǔn)的SPD浪涌保護(hù)器，不能防止瞬時(shí)的過(guò)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(hù)器，避雷器。根據(jù)行業(yè)需要可以定制更大電流浪涌保護(hù)的產(chǎn)品。

3.觸電風(fēng)險(xiǎn)

船舶接地系統(tǒng)故障，會(huì)形成一個(gè)導(dǎo)電的系統(tǒng)，這樣航行的船只就是一個(gè)移動(dòng)的導(dǎo)體！這會(huì)對(duì)船上人員造成生命的威脅，有觸電的危險(xiǎn)。雷電造成的雷擊心臟驟停是致命的！

(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(jí)按二類(lèi)防雷標(biāo)準(zhǔn)進(jìn)行設(shè)計(jì)和施工。避雷針保護(hù)范圍要全覆蓋船體。接地引下線應(yīng)采用屏蔽電纜。

(2)完善等電位連接及屏蔽措施。從室外進(jìn)入艙內(nèi)的各種線纜(信號(hào)線或電源線)應(yīng)穿管屏蔽并做好兩端接地處理。各種設(shè)備外殼及駕駛室門(mén)窗她應(yīng)進(jìn)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(hù)措施。在船舶電源線路安裝三級(jí)電源電涌保護(hù)器。電涌保護(hù)器的標(biāo)稱(chēng)電流、持續(xù)工作電壓、殘壓、安裝方式應(yīng)符合相關(guān)規(guī)范的要求。對(duì)進(jìn)入機(jī)艙的各種信號(hào)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(hào)設(shè)備前端安裝適配的信號(hào)電涌保護(hù)器。

(4)建立健全各項(xiàng)安全制度，制訂雷擊事故發(fā)生應(yīng)急處置預(yù)案。同時(shí)，船上工作人員應(yīng)重視對(duì)防雷設(shè)施的維護(hù):按規(guī)定正確使用各種設(shè)備，尤其是通信設(shè)備，避免遭雷擊損壞。雷暴天氣船上工作人員應(yīng)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(guò)培訓(xùn)并且有能力進(jìn)行自救，具備處理應(yīng)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.
