摘要： PURPOSE:To reduce the ratio of a dielectric in total one turn of a conductor and raise the space factor of the conductor by integrally connecting split wires through a semiconductive layer. CONSTITUTION:Total single wire conductors 10a-10d constitute a layer conductor and each conductor is coated with a semiconductive layer 10j-10m, then kept in contact with each other consecutively and wound with a common insulating paper roll 10i of a dielectric material. The semiconductive layers 10j- 10m have the effect of electrically connecting each single wire conductor substantially for an impulsive electric potential oscillation and the resistivity is selected a value as low as possible which can prevent an eddy current within a wide range of 10 -10 OMEGAm. This construction requires no insulation between single wire conductors and the space factor of the single wire conductors is improved.

摘要： PURPOSE:To prevent moisture absorption of winding in a static inductor device and eliminate necessity of redrying process of the winding of a transformer by storing the wire winding within a container, while only the magnetic legs of iron core are passed through the container, and detaching only the iron core when transporting a transformer whose yoke is located out of the container, transporting it separately and then assempling them in the field. CONSTITUTION:A winding 1 wound with copper wires and insulator paper is accommodated in a container 2 made of thermoplastic resin having a through hole for passing magnetic legs of an iron core 4 and cover 3. Then, silicon steel sheet laminate iron core 4 is brought into close contact with the outside of the container while inserting the magnetic legs into the hole, an outer box 5 is mounted on the lower end of the core 4, and a cooling insulating oil is filled in the container 2 by utilizing the cover 3 to form a transformer 10. When the transformer 10 is thus assembled and transported to a field, only the iron core 4 is pulled out of the transformer, but the winding 1 is retained in oil. After the transformer is transported to the field with such configuration, it is unnecessary to redry or retest the transformer at the field.

摘要： PURPOSE:To relatively simply catch a generating condition of static electricity, by such method that a generating quantity of static electricity in the equipment be obtained on the basis of measurement of a level of drift charge in the insulating fluid made from a fluid directly or indirectly extracted to outside the equipment. CONSTITUTION:With an oil pick-up valve 6 actuated, a fluid is processed sampling from outlet port of an oil pump 5. The fluid, made sampling, flows into a container 10 through a valve 8, where specific resistance or dielectric loss factor of the fluid is measured by a sensor 11, and then drifting in a measuring unit 9. In the container 10, a residual charge, existent in the fluid, is moderated and dissipated before flowing into the measuring unit 9, with a so called pretreatment operated for a measurement of level of the drift charge. If the fluid moves drifting in the measuring unit 9, static electricity is generated in the measuring unit 9, with a signal, that indicates its level, obtained, and its analysis can provide a generating quantity of static electricity in a transformer main unit 1.

摘要： PURPOSE:To improve the dielectric strength over all working temperature ranges as well as to simplify the appliance for reliability improvement by operating a fine droplets generating unit only at the low-temperature time when the detected value of a detector is not greater than a prescribed value. CONSTITUTION:Cooling is carried out by a forced coolant circulation system comprising a pump 17, a condenser 13, a spreader 8 and the like. At the low- temperature start-up time, a fine droplets generating unit 22 is driven first to concentrate ultrasonic waves to the liquid surface of a liquid coolant 5 for allowing an acoustic spring 24 to ascend, thereby causing a tank 1 to be filled with fine droplets having high insulation power, so that a high dielectric strength is provided within the tank and the transformer can safely be introduced into the system even if the vapor pressure of the liquid coolant is low or the previously sealed insulation gas was dissolved into the coolant. After the start-up, due to the temperature rise of the transformer, the vapor pressure of the liquid coolant 5 becomes high and the insulation gas dissolved into the coolant is liberated, so the operation of the fine droplets generating unit is stopped when the liquid temperature detected by a liquid temperature detector 100 reaches a prescribed value.

摘要： PURPOSE:To improve the dielectric strength of a lead wire by a method wherein a part of the insulation at the middle part of a lead wire, i.e. the connection part or bending part, is composed of an insulating layer which is continuous with the insulating layers of the other parts. CONSTITUTION:After a transformer is installed, connecting conductors 5a and 5b are connected. After 1st insulation 7c is applied by taping to the part between 2nd insulation 7a and 3rd insulation 7b, a continuous insulating layer 9a is formed by taping over the connected middle part B and the other parts of a lead wire 3. With this construction, the insulations are mutually bound mechanically and oil gaps are not created between the insulations even if a little external force is applied. Moreover, with this construction, as the surface part of the conductor, where an electric field is highest, is covered with an insulating layer 9b, even if a fine oil gap is created between the insulations, partial discharge is suppressed. With this constitution, the dielectric strength and the mechanical strength of the lead wire can be improved.

摘要： PURPOSE:To test the insulation of a transformer accurately without requiring any large scale installation, by covering the high voltage terminal of the transformer to be tested with an insulator. CONSTITUTION:The high voltage terminal part 4 of a transformer 1 to be tested is covered with a case 6 filled with an insulating oil 7 and the case 6 is connected to the housing of the transformer 1 and is thereby grounded. Since the part 4 is insulated with the oil 7, no large bushings as compared to air bushings are required and since there is virtually no partial electric discharge generated through the parts except the body of the transformer 1, the accurate testing of insulation is made possible.
