  • Electrical tree is studied widely by manufacture state of insulating material fare and blazing fire diagnosis system of use in phenomenon of part discharge that happen for main cause of dielectric breakdown of equipment for electric power. Use process that draw tree pattern here measuring above zero to study special quality of this electricity tree, real-time processing by image processing is proposed because reproduction of tree blazing fire process drops and pattern of tree is difficult correct quantification of tree growth by existent visual observation by involution. This research presents general process that need in image processing of tree blazing fire, and that remove various noises that happen in above zero by measuring electrical tree dividing background and complete view in measured above zero taking advantage of specially proposed complete view object abstraction techniques effectively and quantification of tree becomes easy naturally, can apply to dielectric breakdown estimate because can chase growth process of tree.

  • In the fire there are fusion signs and damage by fire, and insulation aging and carbonization of the electric wiring in the ignition spot because of special characteristic of the appliance in the electricity fire. Because of the physical factor applied in the damage of fire, the decision of ignition spot by eye investigation is insufficient. In this paper, the cause of electricity fire is researched. The focus is on the operation state of operated MCCB(Molded Case Circuit Breaker) at the time of electricity fire. Through grasping the operation principle of MCCB and the experiment, the state of MCCB after fire suppression is discriminated. The distinction possibility on the exist of electricity fire is proposed.

  • According to the principle of ascending water and descending fire, water has the property of wetting downward, which is the opposite of fire, which has the property of blazing upward. Thus, they work differently according to their innate properties. Nature and the human body maintain harmony through the interaction of ascending water and descending fire. When applied to the human body, the heart and kidney are the center of this principle. In other words, the heart above is the fire and the kidney downward is water. When the heart-fire harmonizes downward, the kidney becomes warm, enabling genuine vital functions to be active. When the kidney yin moves upward, the heart receives the nourishing yin to harmonize nutrients and blood. Thereby, physiological functions become normal throughout the blood meridians. However, in the ascending kidneywater and descending heart-yang of the heart and the kidney, the liver and lung are the major functional organs. In other words, the liver through the dispersing and raising yang functions moves water, which is the vital essence of the kidney, upward. And the lung, through the astriction?clearing of the lung and descending Qi?dispersing functions, moves the heart-fire downward. These functions are deeply related with changing seasons; thus, these functions can be explained with the ascending kidney-water and descending heart-yang of the five viscera.

  • Problem of repairing by boring is that it deteriorates stabelety and durability of structure by permeation of seawater from underneath after damage and repair of reinforcing rod regarding of spot. The purpose of this study is to improve the porblem by using the repair method of general boring to mend the of large mat basis. Direction of thes experiment is to apply the new repair material and the method to control the blazing fire factor caused by the crack from the foundation of large mat and also to estimate it's integrity. New method of construction is method of contruction that do speace scurity in vertical drilling and bottom useing water jet. New material used bantonite and rubberized asphalt. Test result existent repair method of construction large size mat basis perforation is difficult and reinforcing rod can be damaged coule there were a lot of problems with re-water leakage of crack repair region, but overcomes existent short coming by method that apply in this study.

  • This paper through shift norm of insulator and research by accident prevention countermeasure special skill authoritativeness verification of insulator and Long Term aging factor for power transmission analysis and evaluate and prove quality of insulator wish to. Assessment technique by aging of own porcelain insulator observes ageing factor for reciprocity comparison through several examinations. Through cool and heat accelerated Aging test, can measure the leakage current change amount that ensue to each Cycle. Can confirm own blazing fire factor as distribution freshness that ensue in HRB Test's hardness value.
