摘要： PROBLEM TO BE SOLVED: To provide a system and a method for simplifying diagnosis of insulation of a pole transformer.
SOLUTION: Deteriorating condition of the pole transformer is diagnosed by applying the laser thereto from the ground even when the pole transformer installed on the pole is not lowered therefrom. Moreover, the distance up to the pole transformer housing wall can be measured by emitting the laser beam from the ground, and receiving the reflected light beam in order to measure vibration in the minute amplitude of the wall surface of the external wall from change of the distance with respect to time. Deterioration of pole transformer means thermal deterioration of the insulation oil and fiber material within the transformer and deterioration of electrical insulation property due to the entry of water. Partial discharge is generated due to deterioration of electrical insulation property. Deteriorating condition at the inside of transformer is detected by observing partial discharge generated therein from the measured fine amplitude of the wall surface, and operation life span is estimated from the result. Since the diagnostic job can be done easily, the pole transformer can be diagnosed totally and the power feeding quality can also be improved.

摘要： PROBLEM TO BE SOLVED: To provide an insulation deterioration diagnostic index whose reliability is high, by adding a new viewpoint to an insulation deterioration diagnostic method for a high-voltage coil. SOLUTION: As a method for evaluating the deterioration of the insulating property of the composite insulator of the high-voltage coil in which mica is stuck with resin, data on all the charge quantities of discharges which exceed a predetermined threshold out of partial discharges which occur when a high voltage is applied, are collected and recorded. On the basis of these, the distribution of the numbers of discharges, the average value of charge quantities, and the total charge quantity of discharges per cycle with respect to the charge quantity of discharges are found and computed, and are used as indexes for deciding deterioration.

摘要： PROBLEM TO BE SOLVED: To provide an ignition coil for an internal combustion engine which has high insulation durability by suppressing the generation of voids in the high voltage section thereof. SOLUTION: A resin section of a skin layer of a bobbin formed of synthetic resin is dissolved to allow the dissolved face of the bobbin skin layer to emerge. Consequently, the surface of the bobbin is activated, increasing the wettability of the surface of the bobbin and thereby suppressing the generation of voids which appear in an interface between the bobbin and an insulation resin material. As a result, the generation of destructive voids which likely appear on the surface of a secondary bobbin is suppressed, and adhesion between the bobbin and the insulation resin material is increased, resulting in an increase in the insulation durability of the ignition coil.
