摘要： PROBLEM TO BE SOLVED: To provide a method and a device for snow accumulation which almost duplicates a snow accumulation state with natural wet snow. SOLUTION: In this method for snow accumulation which performs a snow accumulation simulation by accumulating natural snow pieces or artificial snow pieces to an object 13 to be snow-accumulated, the wet snow 15 is formed by snow-melting surfaces of the snow pieces 12 by irradiating an electromagnetic wave or an electron beam from an electromagnetic wave source or an electron beam source 14 on the natural snow pieces or the artificial snow pieces 12 floating in the air, and the wet snow 15 is accumulated on the object 13 to be snow-accumulated. The snow accretion device 10 performs the snow accretion simulation by accumulating the natural snow pieces or the artificial snow pieces to the object 13 to be snow-accumulated, and an electromagnetic wave generator or an electron bream generator 14 is provided, which irradiates the electromagnetic wave or the electron beam to the natural snow pieces or the artificial snow pieces 12 floating in the air.

摘要： PROBLEM TO BE SOLVED: To provide a method and program for estimating vibration lifetime of an aerial electric wire, capable of estimating the lifetime due to the vibration fatigue of the aerial electric wire mounted to an electric wire gripping section of a discharge clamp.
SOLUTION: The vibration frequency of the electric wire is calculated, based on the distance between poles and the relaxation rate of the aerial electric wire, the wind speed generating frequency is calculated based on the wind direction angle and turbulence of the wind, and the wind speed generating frequency is converted into a stress-generating frequency (S102). The stress generated for each wind speed is determined for the stress-generating frequency, the repetition number, until the wire of the aerial electric wire is disconnected is calculated, based on the vibration frequency (S106-S108). The occurrence time of the disconnection, due to vibration fatigue in the electric wire gripping section of the discharge clamp of the aerial electric wire, is predicted from the repetition number (S110).

摘要： PROBLEM TO BE SOLVED: To provide a slow snow accretion protective pipe for overhead wires, which has a simple shape and structure and is capable of reducing accretion of snow to the overhead wires. SOLUTION: The slow snow accretion protective pipe 1 for overhead wires comprises a cylindrical member 12 of a halved cylindrical structure having a pair of halved members 10, 10, and a water repellent layer 5 formed on the member 12. The cylindrical member 12 is rotatably attached so as to contact the outer circumference of an overhead wire 2 and rotates around the outer circumference of the overhead wire 2 by imbalance of a rotating moment caused by own weight of snow.
