Description

[Detailed Description of the Invention] The present invention relates to a conductor support device for a reduced type switchgear, etc., and is particularly characterized by a structure in which the support height position of the conductor can be freely adjusted.

Electrical equipment such as switches and disconnectors are housed in the tank of the reduced-size switchgear, and these electrical equipment are connected by conductors.

This type of conductor is supported by a support device on the tank wall as shown in FIGS. 1 and 2.

To explain about Figures 1 and 2, 1 is the tank wall of the reduced type switchgear, 2, 2... are the conductors installed inside the tank wall, 3, 3... ... is a conductor support.

This conductor support is attached to a support plate, side wall, etc., which are not shown in FIGS. 1 and 2.

The conventional support has a structure as shown in FIG. 3, in which 4 is a side wall (or support plate) disposed inside the tank, 5 is a molded support insulator that integrally has a mounting bracket 6 at its lower end,
Screw the threaded part of the mounting bracket 6 into the side wall 4 and tighten the nut 7.
It is fixed by tightening it.

Reference numeral 8 denotes a conductor (bus bar) supporting metal fitting integrally molded on the upper end of the mold supporting insulator 5, and a holding metal fitting 9 is applied from the upper surface of the metal supporting metal fitting 8, and the conductor 2 in the support hole 11 is tightened with a bolt 10.

In the support device of the above structure, the height position of the wiring of the conductor 2 must be adjusted, but as described above, the mounting bracket 6
The support insulator 5 and the support insulator 5 are integrally molded, and when adjusting the height, it is necessary to remove the support insulator 5 and insert a seat plate or the like between it and the side wall. This was difficult and required a lot of man-hours to install.

In addition, since the conductor 2 was held between the support fitting 8 and the holding fitting 9 and fixed by tightening bolts, the number of parts was large and manufacturing was not easy.

Furthermore, the installation work in a narrow space inside the tank is even more difficult, and the work of tightening the retainer using a tool such as a screwdriver is no longer easy.

The present invention improves the above-mentioned drawbacks, and will explain the embodiment shown in the drawings.In FIG. 4, reference numeral 12 denotes a mold support insulator, and embedded metal fittings 13. each have a right-handed thread and a left-handed thread at both ends thereof. 13' is molded.

On the other hand, a tap 14 is made on the conductor 2, and a stud bolt 15 is screwed together between the tap 14 and the screw of the embedded metal fitting 13 provided on one end side of the mold support glass 12. By turning the support height of the conductor 2 is adjusted via the gap G.

Further, by embedding the other end of the support insulator 12, the support insulator screws the tip of a bolt 17 inserted into the support column 16, thereby fixing the support glass 12 to the support member 16 such as the support column.

In the fifth illustration, the bolt 17 is attached to a support member 18 such as a side wall (or support plate), and its tip is attached to the support glass 1.
An example is shown in which it is tightened to the screw of the second embedded fitting 13'.

Since the conductor support device according to the present invention has the above-mentioned configuration, the support glass is fixed to the mounting surface such as the support column or the side wall of the support plate by molding embedded metal fittings having reverse threads at both ends of the support insulator. However, since the conductor is supported by the support insulator by the stud bolt, the height of the conductor can be easily adjusted by rotating the support insulator and threading the stud bolt through the gap G. can.

Further, since the shape of the support insulator is simplified, it is easy to manufacture and easy to assemble, even by an unskilled assembly worker.

Furthermore, it is easy to install the conductor in a narrow space inside the tank of the reduced-size switchgear equipment, and the height of the conductor can be easily adjusted, making the work easier.
