Abstract
This paper describes development of technologies for substation equipment that harmonizes with social environment, and the status of their application. For transformers, noise reduction has been realized by adopting step-wrap joints and vibration absorbing steel plates that can improve the magnetic flux flow in iron core joints. A 200-MVA device has the installation space reduced to about two thirds of that for conventional devices. Transformers of 100 MVA to 200 MVA have achieved reduction in noise to less than 55 phones as a result of adopting type A iron plate sound barrier walls and vibration absorbing steel plates. In vibration reducing technologies, the iron core systems are determined of an optimally tightened construction upon analyzing and measuring the inherent values of vibration modes. In order to analyze the vibration phenomenon in operating condition, dynamic and computerized analyses are performed on windings by using a multiple material point vibration system. Non-combustible and flame-retardant constructions have been applied to developments of gas insulated switches, gas insulated transformers, and molded transformers with primary and secondary windings molded simultaneously. Efforts of making device appearance harmonize with environment include unifying the outline dimensions, simplifying and smoothing the shapes, eliminating hazardous feeling and mechanical images, and
