Description

本発明は、配電線と柱上変圧器の間に介在させる高圧引下げ用電線の柱上配線装置に関するものである。   The present invention relates to a pole-side wiring device for a high-voltage pull-down electric wire interposed between a distribution line and a pole transformer.

変圧器の装柱に際し、送電線や配電線などと変圧器の間に高圧引下げ用電線を介在させ、かつ、該高圧引下げ用電線の中間部に高圧カットアウトを配して、過負荷による変圧器の故障防止、当該変圧器以降の短絡電流が高圧線へ波及させるのを防ぐようにしている。   When installing transformers, a high-voltage pull-down wire is interposed between the transmission line, distribution line, etc. and the transformer, and a high-voltage cut-out is placed in the middle of the high-voltage pull-down wire to transform the transformer due to overload. It prevents the failure of the transformer and prevents the short circuit current after the transformer from spreading to the high voltage line.

そして、前記高圧カットアウトは、変圧器と別個に装柱するのが一般である（例えば、特許文献１）が、別個に装柱するには応分の資材を必要とし、そのために配線作業も煩雑となることから、変圧器自体に高圧カットアウトを装備して装柱する手段も採られている（例えば、特許文献２）。   In general, the high-voltage cutout is mounted separately from the transformer (for example, Patent Document 1). However, in order to mount the high-voltage cutout separately, appropriate materials are required, and therefore wiring work is complicated. Therefore, means for mounting a high-voltage cutout on the transformer itself is also employed (for example, Patent Document 2).

The PD adapter and the high-voltage cutout are connected by a second high-voltage pull-down electric wire.

本発明によれば、配電線より分岐した高圧引下げ用電線を電柱に沿わせて配線して柱上変圧器に設けたアダプタに接続するものであるから、前記配電線と柱上変圧器（のアダプタ）間に装柱機器や樹木などの障害物の位置や大きさと無関係に配線でき、電柱に沿わせる一方で、変圧器に支持金具を介して取付けた（定形化して取付けられる）アダプタ、高圧カットアウトを介して変圧器に接続するものであるから、配線状態の画一化を図れ、常に均質な配線状態を得ることができる。   According to the present invention, the high-voltage pull-down wire branched from the distribution line is wired along the utility pole and connected to the adapter provided in the pole transformer. The adapter can be wired regardless of the position and size of the pole equipment and obstacles such as trees, and is installed along the power pole while being attached to the transformer via a support bracket (fixed) and high voltage Since it is connected to the transformer via the cut-out, the wiring state can be made uniform and a uniform wiring state can always be obtained.
