摘要： PROBLEM TO BE SOLVED: To obtain a pole-mounted oil transformer containing a switch, capable of avoiding congestion of apparatus on an electric pole.
SOLUTION: A transformer body 7 having transformer coils 7U-7W is housed in the bottom of a transformer case 6, together with an insulation oil 8, and a switch 14 is housed in an upper space 13 of the case 6. A partition wall 15 for partitioning the oil 8 and the switch 14 is provided on the surface 8a of the insulation oil 8 so as to be deformed due to a rapid pressure rise in a short- circuit trouble in the case 6, thereby allowing the pressure to rise toward the switch 14. The upper part of the case 6 is structured to form an opening for discharging out the rising pressure toward the switch 14 against a rapid pressure rise in the short-circuit trouble in the case 6.

摘要： PROBLEM TO BE SOLVED: To provide an automatic voltage regulator for power distribution and a method of determining a cause of reverse power flow for determining whether the reverse power flow depends on the system switching or on cooperation of dispersed power sources when the reverse power flow is generated in an automatic voltage regulator for power distribution. SOLUTION: When the secondary side voltage of an adjusting transformer 2 shows the change of the threshold value or higher on the occasion that the tap is changed over under the condition that reverse power flow is detected with a power direction relay 9, it is determined that reverse power flow resulting from cooperation of the dispersed power sources is generated. When the secondary side voltage of an adjusting transformer does not show the change of threshold value or higher on the occasion that the tap is changed over, it is determined that reverse power flow resulting from the change-over of system is generated.
