Description

A connection device for combined electric bushing and lead wire

technical field

The utility model relates to a connecting device, in particular to a device used for connecting lead wires and combined electric appliances.

Background technique

Combined electrical appliance is a device that combines two or more electrical appliances and connecting wires into a whole according to requirements, and each electrical appliance still maintains its original performance. It is now widely used in substations and industrial power automatic control systems. As the application of combined electrical appliances increases, the requirements for combined electrical bushings also increase. Commonly used combined electrical bushings include composite bushings and porcelain bushings. The connection boards provided on the conventional combined electrical bushings are long strip-shaped terminal blocks, which are directly connected to the connecting leads, which is not beautiful, but also increases the traction force of the connecting leads to the combined electrical bushings.

Utility model content

The technical problem to be solved by the utility model is to provide a connecting device for a combined electric bushing and connecting lead, which can ensure that the bushing, the upper jumper and the connecting lead are in the same plane, and can also reduce the distance between the connecting lead and the connecting lead. traction.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A connection device for a combined electric bushing and lead wire, comprising a first aluminum row connected to the bushing terminal row, the top of the first aluminum row is connected to an arc-shaped guide block with an angle of 90°, and the arc-shaped guide block The outer end is equipped with a second aluminum row; the second aluminum row is provided with a groove matching the arc-shaped guide block, and the end of the second aluminum row connected to the arc-shaped guide block is provided with two through holes, and the second aluminum row The through hole on the inside of the row is hinged with the inner corner edge of the arc-shaped guide block through the pin shaft, and the outer corner edge of the arc-shaped guide block is provided with several arc-shaped threaded holes corresponding to the through holes on the outside of the second aluminum row; The aluminum row and the second aluminum row are respectively provided with several bolt holes for assembling pressing bolts.

Owing to having adopted above-mentioned technical scheme, the technical progress that the utility model obtains is:

The utility model provides a connecting device for a combined electrical bushing and connecting lead wires, which can ensure that the bushing, the upper jumper and the connecting lead wires are in the same plane, and can also reduce the traction force of the connecting lead wires on the bushing. The first aluminum row and the second aluminum row are hinged through the arc-shaped guide block with a pin shaft, which can adjust the angle of connection between the connecting row and the lead wire; the threaded hole at the outer end of the arc-shaped guide block is used to locate the angle of the two aluminum rows. The position of the connecting row is stabilized, and no deviation occurs during operation, thereby ensuring the minimum external force on the bushing of the combined electrical device and avoiding the influence on the electric field strength inside the bushing.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

A connection device for a combined electric bushing and lead wire, as shown in Figure 2, including a first aluminum row 201 connected to the bushing terminal row, and an arc-shaped guide with an angle of 90° is set at the top of the first aluminum row The block 202 is equipped with a second aluminum row 203 at the outer end of the arc-shaped guide block.

The second aluminum row 203 is provided with a groove 204 matching with the arc-shaped guide block 202, and the second aluminum row 203 and the arc-shaped guide block 202 are connected by a pin shaft 207, and the pin shaft 207 is arranged on the arc-shaped guide block 202 On the edge of the inner corner of the second aluminum row 203 and the inner corner edge of the arc guide block 202, it is ensured that the second aluminum row 203 and the arc guide block 202 can be rotated by 90°. On the outer corner edge of the arc-shaped guide block 202, there are several arc-shaped threaded holes 206 matched with the outer through holes of the second aluminum row 203 to fix the angle between the second aluminum row 203 and the arc-shaped guide block 202 Location.

Both the first aluminum row 201 and the second aluminum row 203 are provided with a plurality of bolt holes 205 used as connection terminals and used for assembling pressing bolts.

The connection bar used to connect the combined electrical bushing and the lead wire is shown in Figure 1. One end of the second aluminum bar 203 of the connection bar 2 is connected to the lead wire 1, and each bolt hole 205 in the connection bar 2 is equipped with a set Bolts and nuts are used as terminals to connect with wires. One end of the first aluminum row 201 is connected to the terminal row on the bushing of the combined electrical appliance. The bushing is a porcelain bushing with good insulation, and a shielding layer and a conductive rod are arranged inside the bushing. , The conductive rod is coaxial with the bushing to avoid causing internal discharge of the bushing.

Since the two aluminum bars in the connecting row 2 are hinged through the arc-shaped guide block and the pin shaft, the angle of the connecting row 2 can be adjusted according to the installation angle of the combined electrical bushing, so that the connecting lead wires and the upper spanning wires are in the same plane, If the installation angle between phase A of the bushing and the horizontal plane is 30°, the angle of the two aluminum rows in the connection row can be adjusted to 120°; if the installation angle between phase A of the bushing and the horizontal plane is 60°, the two aluminum rows in the connection row The angle can be adjusted to 150°. Always keep the lead wire perpendicular to the horizontal plane, reduce the traction force caused by the lead wire to the bushing, and ensure the stability of the electric field strength inside the bushing.
