摘要： PURPOSE:To enable effective cooling of an electric apparatus throughout the use temperature region, by a method wherein at least two sorts of cooling media being different from an insulating medium in vapor pressure characteristic and boiling point are charged in a casing to enclose the electric apparatus and a stirring device is installed in liquid part of the cooling medium formed at lower side of the casing. CONSTITUTION:Cooling media are required to be different in vapor pressure characteristic and boiling point. When two sorts of cooling media are used, one cooling medium having low vapor pressure and high boiling point realizes effective liquid cooling throughout the use temperature region of the apparatus. Other cooling medium having high vapor pressure and low boiling point secures necessary and sufficient vapor pressure even at low temperature since cooling medium of lower boiling point (higher vapor pressure) first evaporates at higher rate, thereby effective evaporation cooling is performed throughout the use temperature region. Insulating medium and cooling medium may be selected widely from many materials. From materials which have been used with good results in gas insulation transformers and reactors, SF6 gas is applied to an insulating medium and fluorocarbon C8F16O and C7F15ON to a cooling medium.
摘要翻译：目的：为了在整个使用温度范围内有效地冷却电气设备，通过一种方法，其中将至少两种不同于具有蒸气压特性和沸点的绝缘介质的冷却介质装入壳体中以封闭电气设备并且在形成在壳体的下侧的冷却介质的液体部分中安装有搅拌装置。构成要素：蒸气压特性和沸点要求冷却介质不同。当使用两种冷却介质时，具有低蒸气压和高沸点的一种冷却介质在装置的整个使用温度区域实现有效的液体冷却。具有高蒸气压和低沸点的其他冷却介质即使在低温也确保了必要且足够的蒸气压，因为低沸点（较高蒸汽压）的冷却介质首先以更高的速率蒸发，从而在整个使用温度区域进行有效的蒸发冷却。绝缘介质和冷却介质可以从许多材料中广泛选择。从气体绝缘变压器和反应堆中使用的材料取得良好效果，将SF6气体施加到绝缘介质和碳氟化合物C8F16O和C7F15ON到冷却介质。

摘要： PURPOSE:To increase the heat resistance, oil resistance and cold resistance of an oil-immersed electric apparatus, by constituting a packing by a rubber material obtained by mixing nitrile rubber and dioctyl sebacate in a predetermined mixing ratio, and employing an insulating oil having an intrinsic resistance value larger than a specific value. CONSTITUTION:Nitrile rubber and dioctyl sebacate are mixed together so that, when the unit quantity of acrylonitrile in the nitrile rubber is A wt%, the pts.wt. of the used dioctyl sebacate with respect to the 100pts.wt. of the rubber is within the range represented by the following expression of relation: 38 OMEGAcm is employed.

摘要： PURPOSE:To save the energy shortening the process time by a method wherein the grooves between the adjusting windings of coil are coated with the adhesive mainly composed of the optical setting synthetic resin radiating ultraviolet rays to the adhesive which is solidified fixing the windings. CONSTITUTION:The grooves 4 formed between the adjoining windings of coil 1 constituted by wound windings 2 are coated with the adhesive 3 mainly composed of the optical setting resin. Then the adhesive is radiated with ultraviolet rays to be solidified fixing the windings. The recommended adhesives 3 are oligoesteracrylate, urethaneacrylate, epoxyacrylate, unsaturated polyester-resin and the like. When the heating process is required after producing the coils, the adhesive may be composed of peroxide producing radical at the temperature added to optical setting resin together with photopolymerization initiator and promoter.

摘要： PURPOSE:To eliminate static charge at a carta without losing cooling effect by installing polyolefin member in a flow passage of mineral oil to make the carta contact with the mineral oil. CONSTITUTION:A carta 1 positively charges mineral oil. On the other hand, polyolefin fibrous paper 2 such as polyethylene, polypropylene negatively charges the mineral oil. Accordingly, the negative charge generated by the carta 1 is recoupled with positive charge generated by the polyolefin fibrous paper 2 to be thus neutralized to thereby prevent static charge at the carta 1.
