Description

  The present invention relates to a switch that switches a primary-side electric wire and a secondary-side electric wire to an electrically connected state or an edge-cut state.

  Various works (for example, replacement work, expansion work, etc.) are carried out on supporting objects (for example, utility poles) that support overhead lines that supply power and installations such as transformers that are electrically connected to the overhead lines. May be.

  In such construction, a power outage work is performed in which only the construction section is cut off. More specifically, a branch line (hereinafter referred to as the first branch line) is connected to the overhead line on the primary side of the construction section, and another branch line (hereinafter referred to as the first branch line) on the secondary side of the construction section. By connecting the first branch line and the second branch line electrically, only the construction section is interrupted.

  When performing the power outage operation described above, if the first branch line and the second branch line are directly electrically connected, the first branch line and the second branch line are immediately charged and dangerous. Therefore, when performing the above-mentioned power failure operation, a switch (so-called construction switch) that switches between a state where the first branch line and the second branch line are electrically connected or a state where the first branch line is cut off is used.

  As such a switch, a switch body having a first connection part that connects the first branch line and a second connection part that connects the second branch line, and a posture changeable with respect to the switch body. In connection with the change, the first branch line electrically connected to the first branch line connected to the first connection part and the second branch line connected to the second connection part, and the first connected to the first connection part Some include an opening / closing part that can be switched to a cut state in which the branch line and the second branch line connected to the second connection part are cut off, and a lifting member provided in the switch body (for example, a patent) Reference 1). Moreover, this type of switch is provided with the control member which can control the attitude | position change of the switch part in a cut state.

Is provided. Therefore, if it is going to lift a switch using a lifting member when an opening-and-closing part is an ON state, a lifting member will remove from a switch main part. Therefore, the switch cannot be lifted with the opening / closing part in the on state. On the other hand, the switch can be lifted using the lifting member by setting the opening / closing part to the off state and fixing the lifting member to the switch body by the locking means.

  In this case, when the lock means is in a lock operation state for fixing the lifting member to the switch body, the change in posture of the opening / closing portion is restricted, and the lock operation state of the lock means is released. It is also possible to provide a restricting means capable of releasing the restriction on the posture change of the opening / closing part when the opening / closing part is in the open position.

  If it does in this way, the posture change of an opening-and-closing part will be controlled with fixing a lifting member to a switch body. Therefore, even if an external force acts on the opening / closing part when the lifting member is lifted, it is possible to prevent the opening / closing part from changing its posture. That is, the switch can be lifted after preventing the switching part from switching from the cut state to the on state.

  As one aspect of the present invention, the lock means is a lock member main body provided in the switch body, the lock member main body into which the lifting member can be inserted, and the lock member main body inserted into the lock member main body. A retaining member for preventing the lifting member from being removed, a state in which the lifting member inserted into the lock member main body is retained by the retaining member, and the suspension inserted into the lock member main body You may make it provide the switching member which can switch the state from which the retaining of the said retaining member with respect to the member was cancelled | released.

  If it does in this way, it can switch to the state by which the lifting member inserted in the lock member main body is prevented by the retaining member by the switching member. In other words, the lifting member can be fixed to the switch body by the switching member. Thereby, the lifting member can be brought into a state capable of being lifted.

  In this case, the restricting means is formed in a long shape, and has a first end in the longitudinal direction and a second end opposite to the first end, and the first end of the restricting means is the switching member. A second end of the restricting means is connected to the opening / closing portion, and the length of the restricting means is such that the switching member is connected to the lock member main body when the opening / closing portion is not in the on state but in the off state. You may make it set to the reachable length.

  In this way, when the opening / closing part is in the on state, the switching member cannot reach the opening / closing part. That is, in order to fix the lifting member to the switch body, it is necessary to switch the opening / closing part from the on state to the off state. Therefore, it is possible to more reliably prevent the lifting member from being lifted when the opening / closing part is in the on state.

  As described above, the switch according to the present invention can have an excellent effect that the switch can be prevented from being lifted when the switch is in the on state.

Therefore, the switch 1 cannot be lifted with the opening / closing part 3 in the on state. On the other hand, the switch 1 can be lifted using the lifting member 4 by turning the opening / closing part 3 and fixing the lifting member 4 to the switch body 2 by the lock means 5. Therefore, the switch 1 according to the present embodiment can have an excellent effect that the switch 3 can be prevented from being lifted when the switch 3 is in the on state.

  Moreover, according to the switch 1 which concerns on this embodiment, it is comprised so that the lifting member 4 may be fixed to the switch main body 2, and the attitude | position change of the switch part 3 may be controlled. Therefore, even if an external force is applied to the opening / closing part 3 when the lifting member 4 is fixed to the switch body 2, the posture of the opening / closing part 3 can be prevented from being changed. That is, when the lifting member 4 is lifted, the opening / closing part 3 can be prevented from switching from the cut state to the on state.

  When the switching member 52 is rotated while being inserted into the closing portion 512 and the rotating portion 510, the lifting member 4 is prevented from coming off and the switching member 52 is also prevented from coming off. Therefore, it is possible to prevent the switching member 52 from falling off from the closing portion 512 and the rotating portion 510 when the lifting member 4 is lifted. Therefore, the switch 1 can be installed on the utility pole more safely.

  It should be noted that the switch according to the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention.
