Description

The present invention relates to a jumper opening / closing device for connecting or disconnecting jumper wires.
In the present invention, fitting the male opening / closing tool to the female opening / closing tool or sliding the fitting to fit the female opening / closing tool is based on the female opening / closing tool. Or sliding to fit.

  When a customer line (factory, etc.) is a transmission line that branches off from a main line, etc., and an accident occurs that makes it difficult to recover quickly, such as a broken power line, a branch tower, etc. is used to isolate the accident section and eliminate supply problems. A switchgear is installed in the jumper. When an accident occurs, the accident section can be separated by disconnecting the jumper opening / closing device attached to the accident section.

  As the jumper opening / closing device, a PG clamp and a compression type opening / closing jumper sleeve are often used. In the case of the PG clamp, when removing the jumper wire, there is a risk of dropping the PG clamp body in order to remove the PG clamp body. On the other hand, in the case of a compression-type opening / closing jumper sleeve, there is a risk of dropping the bolts and nuts used for connection.

  In addition, the operation of opening and closing the jumper switchgear is an unstable task because the operator gets on the overhead ladder, and as soon as possible when opening, the jumper switchgear may fall. There is also a nature, and the physical and mental burden of workers is great. The open jumper line is fixed to the folded power line with a bind line. However, considerable skill, labor and time are required to fold the jumper line. For this reason, in the conventional opening / closing operation of the jumper opening / closing device, it takes about 40 minutes to process one phase, and the number of people is 4-5.

  In order to solve the above problems, several jumper opening / closing devices have been proposed so far. For example, there is a jumper device in which a compression / fixing portion that compresses and fixes one jumper wire and a detachable clamp integrally provided with a clamp-like detachable gripping portion that detachably holds the other jumper wire (for example, Patent Document 1). In this jumper device, one jumper wire is compressed and fixed, so even if one jumper wire is disconnected when it is opened, the jumper device does not fall off, and the attachment / detachment grip for attaching / detaching the other jumper wire is boltless structure This eliminates the need for bolt tightening operations.

  In addition, an opening / closing device capable of remotely operating a jumper wire has been developed in order to isolate an accident section within a short time and to enable recovery (see, for example, Patent Document 2). This jumper opening / closing device performs an opening / closing operation by rotating an electrode blade in the same manner as a disconnector used in a substation or the like.

The same members and configurations as those of the male opening / closing tool 3 shown in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. The movable claw 53 is formed by bending an elastic metal plate into a triangular shape in plan view. One end portion 55 is fixed to the connecting portion 13, and the connecting portion 13 is provided with a storage portion 47 into which the movable claw 53 enters. Since the movable claw 53 has a simple structure, it can be easily manufactured.

  FIG. 9 is a configuration diagram of a jumper opening and closing device as a second embodiment of the present invention. The jumper device is configured by using two jumper opening / closing devices 1 of the first embodiment. Since the configuration of the jumper opening / closing device 1 has already been described, the method of use will be described here. Here, in order to distinguish between the two jumper opening / closing devices 1, one jumper opening / closing device is 1A, and the other jumper opening / closing device is 1B.

  Among the two jumper opening / closing devices 1A, 1B, the jumper opening / closing device 1A is attached to the jumper wires 101, 103. The male opening / closing tool 3A is attached to the jumper wire 101, the female opening / closing tool 5A is attached to the jumper wire 103, the male opening / closing tool 3A and the female opening / closing tool 5A are connected, and the jumper wires are connected. The attachment procedure of the male opening / closing tool 3A and the female opening / closing tool 5A to the jumper wires 101, 103 and the connection procedure of the male opening / closing tool 3A and the female opening / closing tool 5A are as described in the first embodiment. The direction in which the male opening / closing tool 3A and the female opening / closing tool 5A are attached to the jumper wires 101, 103 is important.

  Since the jumper wires 101 and 103 to which the male opening / closing tool 3A and the female opening / closing tool 5A are connected are floating in the air as shown in FIG. 9, a load is applied to the jumper wires 101 and 103 in a direction to separate them from each other. . Therefore, the male opening / closing tool 3A with respect to the jumper wire 101 is such that the direction in which the male opening / closing tool 3A is fitted into the female opening / closing tool 5A is opposite to the direction in which the jumper wires 101, 103 are separated from each other. The female opening / closing tool 5 </ b> A is attached to the jumper wire 103.

  When the male opening / closing tool 3A and the female opening / closing tool 5A are connected in this state, even if the jumper wires 101 and 103 try to separate each other, the movable claw 35 is locked to the fixed claw 36 so that it does not come off. . Even if the direction in which the male opening / closing tool 3A is fitted into the female opening / closing tool 5A and the direction in which the jumper wires 101 and 103 are to be separated from each other coincide with each other, the stopper 37 prevents the movement of each other, so However, it is more reliable to lock the movable claw 35 to the fixed claw 36.

  The other jumper opening / closing device 1B attaches the male opening / closing tool 3B and the female opening / closing tool 5B to the power lines. Specifically, the female opening / closing tool 5B is attached to the power line 105 connected to the jumper wire 101, and the male opening / closing tool 3B is attached to the power line 107 connected to the jumper wire 103. The attachment positions of the male opening / closing tool 3B and the female opening / closing tool 5B with respect to the power lines 107 and 105 are the clamp 109 that connects the power line 105 and the jumper line 101, and the clamp 111 that connects the power line 107 and the jumper line 103. The vicinity is preferable. The attachment procedure of the female opening / closing tool 5B to the power line 105 and the male opening / closing tool 3B to the power line 107 is the same as the attachment procedure to the jumpers 101 and 103.

  If the female opening / closing tool 5B is attached to the power line 105, even if the jumper opening / closing device 1A is opened and the jumper line 101 is disconnected, the male opening / closing tool 3A attached to the jumper line 101 is connected to the female line on the power line 105 side. It can be easily connected to the mold opening / closing tool 5B, and the terminal processing of the jumper 101 line can be easily performed. The same applies to the jumper 103 line. The attachment direction of the female opening / closing tool 5B with respect to the power line 105 and the male opening / closing tool 3B with respect to the power line 107 is such that the jumper wires 101 and 103 are separated when the male opening / closing tool 3A and the female opening / closing tool 5A are connected. The direction in which the intended load is applied and the direction in which the movable claw 35 is engaged with the fixed claw 36 are matched. This is the same as when the male opening / closing tool 3A and the female opening / closing tool 5A are attached to the jumper wires 101, 103.

  As described above, in the jumper opening and closing device shown in the second embodiment, the terminal opening of the separated jumper wires 101 and 103 does not require a bind wire, and the male opening and closing tool 3A is slid into the female opening and closing tool 5B. Since it is only necessary to slide the mold opening / closing tool 5A into the male opening / closing tool 3B, terminal processing can be performed very easily. When the male opening / closing tool 3A is slid into the female opening / closing tool 5B or the female opening / closing tool 5A is slid into the male opening / closing tool 3B, the movable claw 35 is locked to the fixed claw 36 even during the insertion, so that it falls off. It is very easy to use because it prevents it.

  The present invention is not limited to the above-described embodiment, and various modifications can be used without departing from the spirit of the present invention.
