Description

Technical Field

[0001] The invention belongs to the technical field of switchboard protection in a ship manufacturing process, and in particular relates to a ship switchboard protection device and method. Background Art

[0002] The switchboard is an important part of the entire ship power system. Depending on the ship type, the number and size of the switchboards on board are also different. In particular, the maximum length of the switchboards of some large ships with a high degree of automation, such as LNG and large container ships, can reach about 10 meters. During the construction of the ship, the switchboard is often exposed to the rain or other possible top pipe or structure leakage. As a result, the switchboard is at risk of water damage. At present, the protection method of the switchboard is generally to protect the top of the switchboard with plastic paper and three-proof cloth, but the top is prone to water accumulation. For large-sized switchboards, since there is no plastic paper that meets its size, the plastic paper for protection needs to be spliced, and a small amount of water will leak into the switchboard through the splicing of the plastic paper due to water accumulation, which will cause damage to the electronic components in the switchboard and suffer huge economic losses.
