Description

  The present invention, for example, simplifies the connection work even when the terminal shape of the counterpart device to which the bypass cable is connected is a battledore terminal board when performing temporary power transmission work in a state where the distribution path is uninterrupted. It relates to an adapter for cables.

When a device placed in the distribution line breaks down or is replaced regularly, a bypass path that bypasses the device is formed using a bypass cable, and the consumer is supplied with commercial power ( The emergency restoration method is performed after the current at the work site is stopped while maintaining the power transmission from the utility pole (electric pole) and the emergency power supply (high-voltage generator car).
When emergency repair work without a power outage is performed in the event of a supply hindrance in front of a customer's electrical facility, for example, a power receiving facility, temporary power transmission should be performed with a bypass cable directly connected to a normal power receiving facility. Temporary power transmission methods are performed, but in many cases, a battledore terminal plate is used as a terminal on the power receiving facility side to which the bypass cable is connected.

The battledore terminal plate is formed by penetrating a plurality of bolt fastening holes on the plate surface of the conductor plate, and with the bolts in a state where the surfaces are joined so that the bolt holes of the two battledore terminal plate are aligned. By fastening, an electromechanical connection is ensured.
In such a case, it is possible to connect a battledore terminal plate to the end of the bypass cable in the field work after preparing a battledore terminal plate having a size and shape that can be connected to the battledore terminal plate on the power receiving equipment side. Not easy. Therefore, normally, as shown in FIGS. 7A and 7B, the connection fitting 101 is connected to the end of the conductor exposed by peeling off and removing the insulating coating at the end of the bypass cable 120, and this connection is made. In the state where the holes of the metal fitting 101 are communicated with the respective bolt holes 111 of the battledore terminal board 110 on the power receiving equipment side, an operation of individually connecting and fixing using the bolts 115 and the nuts 116 is performed.
However, this work is also an inefficient work that requires labor and time.

Patent Document 1 (Japanese Patent Laid-Open No. 6-351146) discloses a bypass cable adapter that can be plug-in connected to a bypass cable terminal portion and can be connected to various types of lead wires having different wire diameters. This adapter has a battledore terminal at one end and a cylindrical portion (screw groove) for connection to another cable at the other end. The tubular part has a structure in which a bypass cable terminal part is screwed.
Patent Document 2 (Japanese Patent Laid-Open No. 2002-199572) discloses a trunk branch structure having a radial configuration in which one end portions of a plurality of battledore terminals are connected.
Further, Patent Document 3 (Japanese Patent Laid-Open No. 6-351145) discloses a bypass cable terminal portion in which the angle of a battledore terminal plate attached to the end of the cable is changed.

By the way, if the total current value required to be supplied from the bypass cable to the battledore terminal board on the power receiving facility exceeds the allowable current value of one bypass cable, multiple bypass cables can receive power. Although it is necessary to connect to one battledore terminal board on the equipment side, the adapter disclosed in the above Patent Documents 1, 2, and 3 and the structure of the bypass cable terminal part have one battledore terminal as an emergency measure on site. It was difficult to perform an operation of connecting a plurality of battledore terminal boards to the board.
The above problem occurs not only in the power receiving equipment but also in various voltage regulators equipped with a battledore terminal plate and high voltage devices such as a high voltage switch, and therefore, improvement is required.
