日本近几年制订了一系列海洋开发计划,现就其中与电工设备有关的项目摘要介绍如下: 海底土木施工机械系统:是在70米深海底进行平整、挖掘、钻孔、打桩等作业的遥控操作单能作业机,计有推土机、铲土机、钻孔机、打桩机等。此项目以日立造船公司为主,共15个公司参加,东芝公司承担用于这些机械的海中电动机的研制,神钢电机公司为控制系统,三菱电机为配电设备,富士电机公司协助东芝搞海中电动机,日立制作所负责海中自动控制设备。计划70年进行基础研究及基本设计,72年试制样机,预定73年进行实验。总经费预计为8亿日圆。
In recent years, Japan has formulated a series of marine development plans. The summary of the projects related to electrical equipment is presented below: Submarine civil engineering machinery system: remote control of operations such as leveling, excavation, drilling and piling at the depth of 70 meters. Operating single-energy machines, including bulldozers, power shovels, drilling machines, pile drivers, etc. This project is dominated by Hitachi Shipbuilding Corporation. A total of 15 companies participate in the project. Toshiba Corporation is responsible for the development of marine motors used in these machines. Kobelco Electric is the control system, Mitsubishi Electric is the distribution equipment, and Fuji Electric Corporation assists Toshiba in the development of the sea. As a motor, Hitachi Ltd. is responsible for the automatic control equipment in the sea. It plans to carry out basic research and basic design for 70 years, prototype production for 72 years, and experiments are scheduled for 73 years. The total funding is expected to be 800 million yen.
