Problems solved by technology

However, it is obvious that for ships with large main dimensions, such a lighting arrangement will lead to low illumination in the cargo hold area and dead angles in the cargo hold lighting, which cannot fully meet the requirements of the shipowner.
[0003] At present, some of the newly launched LED cargo compartment floodlights on the market can meet the explosion-proof requirements of IICT4, and there is a tendency to replace ordinary metal halide lamps. However, at this stage, there are generally disadvantages such as high prices, quality and lifespan that have not been effectively verified. , resulting in an increase in shipbuilding costs

Abstract

The invention discloses an application system and method of a common metal halide lamp for occasionally carrying dangerous goods in the cargo area of a ship, wherein the application system of the common metal halide lamp for occasionally carrying dangerous goods in the cargo area of the ship comprises a cargo space lighting sub-box with a circuit breaker, a metal halide discharge lamp, wherein themetal halide discharge lamp is connected to the circuit breaker; the circuit breaker is provided with a shunt trip coil, and is further provided with a cargo space discharge lamp control board, and the shunt trip coil is connected to the cargo space discharge lamp control board; the cargo space discharge lamp control board is provided with a mechanical locking device which is used to control thecargo space discharge lamp control board in an operable or non-operable state. According to the application system, the construction cost of the ship is greatly reduced, and the application system hasthe advantages of compact structure, convenient operation and high safety.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a system and method for applying a common metal halide lamp in the cargo hold area of ​​a ship occasionally carrying dangerous goods. Background technique [0002] At the beginning of the ship design, in order to enhance its ability to collect cargo as much as possible, it is generally designed to be able to carry dangerous goods. However, in actual operation, most ships do not carry dangerous goods on many voyages, and only occasionally carry dangerous goods. Once the ship is designed to carry dangerous goods, the cargo hold area will be designated as a dangerous area. The rules and regulations of IEC and major classification societies must comply with the highest explosion-proof standards for dangerous goods intended to be carried for all electrical equipment used in the hazardous area. The type is selected according to the grade, and the explosion-proof grade is generally requir...
