摘要： PURPOSE:To improve the efficiency of concentration by electrodialysis processing by returning residual liquid which is on the side of concentrated liquid before the an electrodialyser starts operating to the supply liquid tank of a reverse osmosis device. CONSTITUTION:The demineralized water on the side 6a of the supply liquid of the electrodialyser is recycled to the reverse osmosis supply liquid tank 2a through a line (j). Consequently, the salt concentration of intermediate concentrated liquid supplied to the electrodialyser 6 through a line (g) decreases gradually and when the concentration of the intermediate concentrated liquid reaches the density where the efficiency of the electrodialysis processing decreases, e.g. 30g/l, the line of the intermediate concentrated liquid is switched from (g) to (f) to quit the electrodialysis processing, thereby cyclic concentration by the reverse osmosis device. In this case, the residual liquid on the concentration side 6b of the electrodialyser decreases on the whole, so this residual liquid is returned to the reverse osmosis supply liquid tank 2a through the line (j). Consequently, a decrease in the concentration of the concentrated liquid obtained finally is prevented to some extent.

摘要： PROBLEM TO BE SOLVED: To simplify the construction of connection between bushings and facilitate connecting work. SOLUTION: When enclosed electrical apparatuses are displaced adjacently to each other, the tips of horizontal conductors 22 in T-shaped bushings 20 are opposed to each other because the horizontal conductors 22 have substantially the same length as the width W of closed vessels. Therefore, T-shaped bushings 20 can be connected together just by joining together the tips of horizontal conductors 22. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To simplify the contact resistance measuring work while enhancing the contact resistance management accuracy by forming a removable plug to have a specified creeping angle with respect to the central axis so that the size can be selected easily. SOLUTION: A cable side conductor 22 is buried in an epoxy resin molded insulation layer 23 and disconnecting conductors are buried on the opposite sides of a bushing while intersecting the cable side conductor 22 perpendicularly or insulating plugs 24 are fixed in the direction matching the central axis of a machine side conductor. Outer circumferential surface of the insulating plug 24 touches the insulation layer 23 at a desired creeping angle θ with respect to the central axis of the disconnecting conductor. Furthermore, a ground layer 25 is formed by applying a conductive paint. In the relationship of the insulating plug 24, the creeping angle θand the AC breakdown voltage or the lightning impulse breakdown voltage, the breakdown voltage is maximized at a creeping angle θ=30 deg.. Consequently, the available region is limited to the range of creeping angle θ=20-40 deg..

摘要： PURPOSE: To reduce the field strength of a portion of contact for the miniaturization of the outer form of a bushing by providing a circumferential recess in the portion of epoxy resin in contact with the high pressure side of a bar-shaped conductor, the epoxy resin being injected in a cylindrical shape around the outer periphery of the conductor. CONSTITUTION: A circumferential recess 6 is formed in the portion of contact between a conductor 1 and the surface 2c of epoxy resin 2 that is made almost cylindrical at the outer periphery of the conductor 1. The field strength of a triple junction 8 where the conductor 1, the surface 2c and an insulating gas 7 make contact with one another is thereby decreased, so that even if the height L of the surface 2c is reduced the withstand voltage required is satisfied, resulting in the miniaturization of the outer form of the bushing itself. Preferably the sizes A, B of the recess 6, as measured parallel and perpendicular to the conductor 2, respectively, are both 5mm or more and 10mm or less. Alternatively, a flexible low-dielectric-constant insulating material whose dielectric constant is greater than that of the insulating gas 7 but smaller than that of the epoxy resin 2 may be packed into the recess 6 to further enhance the withstand voltage characteristic.
