摘要： PURPOSE:To avoid danger such as rupture and scattering by comprising filler composed of single silicon gel or composite substance of silicon gel and inorganic grain insulating material. CONSTITUTION:Filler which is composed of single silicon gel or composite substance of silicon gel and inorganic grain insulating material is comprised. The silicon gel 18 has not only excellent electrical and thermal property but also has cohesion and adhesion in a gelatin form after curing. As a result, if an insulating tube 11 is damaged or broken due to lopsided heat, because it is separated in pressure from an electric apparatus mainframe no rupture occurs resulting from inner pressure. The cohesion and adhesion of the silicon gel prevents the fragments of an insulator portion from scattering. It is thus possible to ensure safety that is free from rupture and scattering if damages such as crack, rib-chipping, etc., to the bushing insulating tube 11 take place.

摘要： PURPOSE:To reduce accidents due to lightning surge voltage, by providing discharge electrodes at tip parts of elastic conductors, which have one ends fixed to input terminals of a watthour meter and are parallel with each other, to absorb a lightning surge voltage in the input terminal side of the watthour meter. CONSTITUTION:Elastic conductors 10 have one ends fixed to input terminals 1 and 2 in the power source side of a watthour meter, which is fitted to an insulating base 9, in parallel with each other by tightening screws 12, and discharge electrodes 11 face to each other at tip parts of elastic conductors 10 with a gap interposed and are fixed by welding. An insulating spacer 13 is inserted near discharge electrodes 11 between elastic conductors 10 to hold a discharge gap length. If a lightning surge higher than the protection level invades between input terminals 1 and 2, the gap between discharge electrodes 11 is discharged to limit the lightning surge voltage to a level lower than the protection level, and an electromangetic repulsive force acts upon elastic conductors 10 by a dynamic current accompanied with discharging to increase the gap length between discharge electrodes 11, thus cutting off the lightning surge. As the result, the dielectric breakdown in the indoor load side, the electric shock, and the occurrence of a fire are prevented.

摘要： PURPOSE:To secure insulating reliability by connecting an end of a crossover to a lead conductor of a propulsion coil and relay-connecting the middle of the conductor in a connecting vessel and the other end of the crossover to the lead conductor of an adjacent other propulsion coil and then, filling the inside of the connecting vessel with silicone gel. CONSTITUTION:The conductor 103 of a crossover 21A is supported to the inside center of a cylindrical vessel 101 by each insulating spacer 102. Then one end of the conductor 103 is screwed in and connected to the end part of a lead conductor 4 of a propulsion coil 2 and the other end of its conductor 103 is connected to the conductor 108 of a crossover 40A at almost the center of a connecting vessel 31A through a connecting conductor 110. Then, after finishing connection and sealing of the conductor, silicone gel which is vacuum-deaerated is injected into the inside of the connecting vessel 31A and deaeration under reduced pressure is performed. Then, after setting at a normal temperature, properties of an agar-like shape are obtained. Silicone gel is superior in a resistance to breakdown strength, heat-resisting, a resistance to an environment, and safety properties and is equipped with vibration absorptive, stickness and adhesion properties. Highly insulating reliability even to vibration and shock is thus obtained for a long period.
