电气产品是船舶的重要设备,随着船舶运输事业现代化发展的需要,越来越被人们所重视。如果说,船用柴油机是船舶的心脏。那末,船舶电气设备就相当于船舶的神经系统。在制订船舶电气产品的技术条件时,要考虑对电气产品有关性能、强度、寿命等各种使用要求,其工作条件是由船舶具体的工作条件决定的。它无疑与陆地上使用的工作条件有许多不同。茫茫的海洋,湿热多变的海上气候。同时,在海面上大气中含有大量的盐雾。这些都是我们在制订产品技术条件时,以及在标准验证工作中必须重视的,也是通过试验必须解决的重要问题。下面就湿热、盐雾、霉菌(简称为三防试验)对电气产品的影响谈一点看法:一、湿热与湿热试验船舶在海洋上航行或停靠在港湾,江湖上。由于太阳的幅射,引起大量水的蒸发。因此,水面上的空气往往是十分湿潮的。尤其在夏天,不但空气潮湿,气温高,而且不易散发。船用电气产品就有很长一段时间在 Electrical products are important equipment for ships. With the demand for the modernization of ship transport, more and more attention has been paid to electrical products. If you say that marine diesel engine is the heart of the ship. Then, the electrical equipment of the ship is equivalent to the nervous system of the ship. In the development of ship electrical products, technical conditions, the electrical products to be considered on the performance, strength, life and other requirements, the working conditions of the ship is determined by the specific working conditions. It undoubtedly has many differences from the working conditions used on land. The vast ocean, hot and humid sea climate. At the same time, the atmosphere on the sea contains a lot of salt spray. These are all important issues that we must pay attention to when formulating product technical conditions and standard verification work, and also important issues that must be solved through experiments. The following on the hot and humid, salt spray, mold (referred to as the three anti-test) on the impact of electrical products to talk about a point of view: First, hot and humid test vessel sailing on the ocean or docked in the harbor, rivers and lakes. Due to the sun’s radiation, it causes a lot of water to evaporate. Therefore, the air on the water is often very wet. Especially in the summer, not only the air humid, high temperature, but not easy to distribute. Marine electrical products have been around for a long time
