摘要： PROBLEM TO BE SOLVED: To obtain a transformer in which the impact of voltage drop on a system is below a fixed level at the time of power-up of the transformer and loss evaluation is enhanced by low loss.SOLUTION: A low loss transformer is designed so that the scale factor of an excitation rush current to a rated current is less than a predetermined vale while limiting the voltage drop rate to a design value, and the short circuit impedance has a value within a standard range determined by the voltage rank of the transformer or a value of the same level as that of an existing transformer. The rated flux density of the transformer is estimated to be less than 1.2 Tesla.

To connect connecting terminals 3a, 3b of the two circuits downward, the connecting surfaces of the connecting terminals 3a, 3b are disposed perpendicularly to the connecting surface of the terminal 2 and to hold the branch adapter. Further, the branch adapter 7 is formed in the structure in which the branch adapter 7 can be clamped separately by respective clamping bolts 5b so that the connecting terminals 3a, 3b are separately attached to or detached from the branch adapter. To connect the connecting terminal 3c upward, the branched adapter 7 is formed in the structure in which the connecting surfaces of the connecting terminal 3c are disposed in parallel to the connecting surface of the terminal 2 and can be clamped.

摘要： PROBLEM TO BE SOLVED: To provide with a simple structure a bushing, capable of relieving the inner pressure of a transformer and improving hermeticity at the bonding portion of a mold cone portion to a porcelain tube. SOLUTION: The inside cylindrical portion of a porcelain tube 1 on a mold cone 2 bonding portion side is shaped as a truncated cone, and the molded portion 3 of an outdoor wiring side lead wire which is embedded and bonded in the porcelain tube 1 is shaped as a truncated cone. The inside of the larger- diameter side bottom inside the truncated cone is grooved concentrically with the lead wire on its axis and molded in a skirt form, and the groove is filled with synthetic resin, which is hardened. This constitution can relieve the inner pressure of a transformer by through the means of the side surface of the truncated cone of the portion 3. Furthermore, the lead wire can be easily put into the tube 1 by making cutaways 4 in the portion molded in a skirt form.
