を接続し分流抵抗に電流を流していた。[Prior Art] Conventionally, in this type of arrester aging circuit, when the discharge start voltage of the arrester is high, the secondary current of the transformer becomes discontinuous, resulting in a rush state in which the current flowing through the transformer transiently increases. Therefore, a shunt resistor was connected to the secondary side of the transformer and a current was passed through the shunt resistor.

スタ５とを有して構成される。FIG. 1 is a circuit diagram of an embodiment of the present invention. In this embodiment, a transformer 2 for transforming an AC primary voltage supplied to the primary side through a switch 1 to output a predetermined secondary voltage from the secondary side, and a transformer 2 connected in parallel to the secondary side. The shunt choke coil 3 and the arrester 5 that is connected to the secondary side of the transformer 3 via the aging current limiting resistor 4 for current limiting and is discharged at a predetermined voltage to supply the aging current for testing. Configured.
開閉器１を閉じトランス２の二次電圧がアレスタ５の放
電開始電圧以上になるとアレスタに電流が流れる。二次
電圧が下がり０「Ｖ」になるとアレスタは再び二次電圧

連続とならず、しかも分流用チョークコイル３に流れる
電流は位相が90°遅れているため電力を消費せず発熱も
ない。また、トランス２の一次電流も低くなる。When the switch 1 is closed and the secondary voltage of the transformer 2 becomes equal to or higher than the discharge start voltage of the arrester 5, a current flows in the arrester. When the secondary voltage drops to 0 “V”, the arrester does not discharge again until the secondary voltage becomes equal to or higher than the discharge start voltage, so that no current flows in the current limiting resistor 4. However, since the current flows through the shunt choke coil 3, the primary current of the transformer 2 does not become discontinuous, and because the phase of the current flowing through the shunt choke coil 3 is delayed by 90 °, no power is consumed and no heat is generated. Absent. Further, the primary current of the transformer 2 also becomes low.
