Description

Bypass device for separating jumpers in overhead transmission lines{BYPASS DEVICE FOR SEPARATING JUMPER OF OVERHEAD TRANSMISSION}

The present invention relates to a bypass device for separating jumpers of an overhead transmission line, and more particularly, an overhead transmission line capable of preventing a safety accident of a worker due to an abnormal current and an induced current flowing from a live line to a cease-fire line when working on a transmission line. It relates to a bypass device for separating a jumper from a furnace.

In general, work on the transmission lines disposed along the transmission tower is performed in a cease-fire state in which the supply of electricity is cut off, and even during the cease-fire (diagonal) work of such a transmission line, it flows into the work line from a live line located nearby. Electric shock accidents due to abnormal current and induced current are frequently occurring.

Accordingly, various grounding devices for line work are used to prevent injuries to workers due to electric shock in the process of working on the transmission line, but since the voltage induced from the live line is high depending on the type and angle of the transmission line, it is necessary to separate the jumper lines from the truce line. There is an urgent need for a jumper wire bypass connection tool.

Conventionally, the separation of jumper wires is performed after thermal image diagnosis of a connection part or connection point between a new line of a transmission line and an existing line is preceded. As a result, urgent and precise inspections are carried out on the target extraction site where heat has occurred, and even during detailed inspection, the tightening condition of the socket connection part of the compression human clamp is also checked. In this process, when the presence of an oxidizing plant at the connection portion of the jumper socket is confirmed, the operation of separating the jumper socket and then removing the oxide film is often performed.

However, even in such a work, there is no specified bypass connection tool, so when connecting and disconnecting jumper wires in transmission lines, conventionally, a method of winding and fixing an arbitrary bypass bind wire on the surface of the transmission line and jumper wire is used, or by connecting a ground wire to the clamp. Since it is used as a grounding clamp by cutting the ground wire or cutting the ground wire, there has been a problem in that there is a problem in that there is a problem of occurrence of an electric shock accident due to an induced current and a lack of safety due to the separation of jumper wires due to unstable contact.

In particular, when disconnecting and connecting jumper wires of conventional compression human clamps, there is a risk of poor contact of wires and separation of jumper wires due to the use of arbitrarily manufactured bypass wires or copper binds. When the bypass line is arbitrarily connected to the overhead transmission line and the jumper line without the use of, the risk of a safety accident is further increased due to voltage induction due to induction.
