It can be used and is easy to use.
配電用変圧器が故障等で交換する場合、或いは
変圧器、高圧側機器の点検、修理、工事を行う場
合、変圧器接続体より分岐用接続体を外して変圧
器近辺の取付け杆に取付け、分岐用接続体を利用
して容易、迅速、安全にバイパス回路を構成し、
無停電で需要家に電力を供給しながら、交換、点
検、修理、工事等の作業を行うことができる。 When replacing a distribution transformer due to a breakdown, or when inspecting, repairing, or constructing a transformer or high-voltage side equipment, remove the branch connector from the transformer connector and attach it to the mounting rod near the transformer. Configure bypass circuits easily, quickly, and safely using branch connectors.
It is possible to carry out work such as replacement, inspection, repair, and construction while supplying power to consumers without interruption.
変圧器接続体の一端を螺杆として既存の変圧器
の内部端子に接続できるようにしたので、既存の
変圧器の螺子締め接続端子と交換でき、現在大量
に使用されている既存の変圧器を容易にバイパス
給電型の変圧器とすることができる。 One end of the transformer connection body is a screw rod that can be connected to the internal terminal of an existing transformer, so it can be replaced with the screw connection terminal of an existing transformer, making it easy to connect existing transformers that are currently being used in large quantities. It can be a bypass-fed type transformer.
さらに変圧器接続体と分岐用接続体は柱上の変
圧器の外部に設けるため接続状態が外部から目視
でき、通常配電、バイパス配電の区別を判別し易
い。 Furthermore, since the transformer connection body and the branch connection body are provided outside the transformer on the pole, the connection state can be visually observed from the outside, and it is easy to distinguish between normal power distribution and bypass power distribution.
