Description

Bypass Cable {BYPASS CABLE}

The present invention relates to an uninterruptible replacement bypass cable, and a work used by connecting a bypass cable and a temporary cutout switch when replacing a cut-out switch (COS) can be used without a temporary cutout switch. The present invention relates to an uninterruptible replacement bypass cable.

The cut-out switch (COS: Cut-Out Switch) is installed to electrically connect or short-circuit the middle of the branch wire that is wired to the customer from the processed high-voltage wire that is wired to the pole. It is a device to check whether there is an abnormality in the line of the customer or the customer. That is, it protects the single-phase distribution line or blocks the failure of the column transformer to prevent the failure from spreading to the entire distribution line.

In the case of replacing the cutout switch, it is necessary to proceed without interrupting the electricity supplied to the customer side. Therefore, the replacement work is performed while bypassing the electricity using the bypass cable and the temporary cutout switch. I'm going.

That is, one end of the first bypass cable is connected to the high voltage wire, the other end of the first bypass cable is connected to one end of the fuse of the temporary cutout switch, and one end of the second bypass cable is connected to the temporary cutout switch. Connect to the other end of the fuse, and perform the replacement work while the other end of the second bypass cable is connected to the transformer terminal.

However, such a replacement work has to be carried out with two bypass cables and temporary cutout switches, and thus the workability is not only degraded, but a problem that is likely to lead to safety accidents during the connection process has been raised.

In addition, there is a need to call the operator's attention because it is not known whether electricity is flowing through the bypass cable.

In addition, the bypass cable is generally finished with a silicone coating, but when the cable is damaged during work, storage and transportation, the expensive cable has to be disposed of, so there is a need to solve this problem.

(0001) Domestic registered utility model publication No. 20-0441978 (Uninterruptible replacement bypass cable of underground low voltage connection device)

The technical problem to be solved by the present invention is to provide a bypass cable configured to perform an uninterruptible replacement operation using only one bypass cable with a built-in fuse.

Another technical problem to be solved by the present invention is to provide a bypass cable configured to alert the operator to a safety accident by turning on the lamp when energized.

Another technical problem to be solved by the present invention is to provide a bypass cable that can prevent the damage to the cable wrapped with a sheath of silicon sheathed shield coating made of nylon.

The bypass cable of the present invention for achieving the above technical problem, the cable in which the wire is built-in; A first terminal coupling part connected to the wire and formed at one end of the cable and connected to any one of a high voltage wire or a transformer terminal; And a second terminal coupling part connected to the wire and formed at the other end of the cable and connected to another one of a high voltage wire or a transformer terminal. The second terminal coupling part includes a first terminal coupling part and a second terminal coupling part. One is characterized in that the removable fuse is built.

In addition, any one of the first terminal fastening portion and the second terminal fastening portion is characterized in that it is further provided with a detector which is turned on when the electricity (through).

In addition, the outer periphery of the silicone coating is characterized in that it is wrapped in a shield cloth woven in nylon material.

According to the present invention as described above, by inserting a removable fuse inside the terminal connection portion of the bypass cable, it is not necessary to use a separate temporary cutout switch can greatly improve the work convenience, separate temporary cut during work The maintenance and management is very easy because only the bypass cable according to the present invention is carried without the out switch and the extra bypass cable.

In addition, by providing a detector that is turned on when the terminal fastening part is energized, it is possible not only to call the operator's attention to safety accidents during the working time, but also to raise safety awareness.

In addition, a shield sheath made of nylon material on the outer circumference of the silicone sheath can prevent cable damage that may occur during storage, transportation, and work, thereby extending the life of expensive bypass cables. Maintenance cost can be reduced.
