Description

Rack Assemblies

The present invention relates to a rack assembly coupled to an electric pole and used for wiring of an overhead distribution line.

Household electric power is supplied to electric power users through wiring of overhead power distribution lines. In detail, the power of 22.9 kV converted from the substation through the column transformer installed in Jeonju is converted into low-voltage power of about 230V and supplied to each household.

Accordingly, the overhead power distribution line is formed to extend low-voltage lines or neutral lines to the poles installed at regular intervals. The low-voltage power converted by the column transformer is supplied through a low-voltage line, and a neutral line is provided to allow an unbalanced current or a fault current to flow when a fault occurs.

In general, a low voltage line or a neutral line is coupled to a rack band formed to accommodate a low pressure human insulator in a rack band formed to surround the electric pole, and a low voltage line or a neutral line is connected to the low pressure human insulator, so that the low voltage line or the neutral line is extended and connected.

Generally, the rack assembly 20 is disposed between the electric wire 2 and the electric pole 1. The electric wire 2 may be a low voltage line or a neutral line. The electric wire 2 is coupled to each other as shown in FIG. 5 through the rack band 21, the rack 22, the low-pressure human insulator 23, the human strap 24, and the tension clamp 25.

Referring to FIG. 5, the rack band 21 may be installed on the electric pole by forming a closed shape surrounding the electric pole 1 and inserting auxiliary materials such as bolts and nuts to tighten. In addition, the rack 22 is installed in the rack coupling portion 21a of the rack band 21 by inserting subsidiary materials such as a bolt and a nut to install the rack 22, and the low pressure insulator pin on the rack 22 (23a) is inserted and coupled, and the electric wires are extended by connecting the tension clamps (25), which form wires (2), such as low-voltage wires or neutral wires, to the low-pressure human insulator (23).

However, the conventional rack band 21, rack 22, low-pressure human insulator 23, and human strap 24 are mostly made of iron and magnetic material, which is problematic.

In addition, conventional racks were formed in multiple types for one-wire, two-wire, three-wire, and four-wire, so it was difficult to apply them according to the application. In addition, in order to attach the rack to the rack band, it is combined with small sub-materials such as split pins, bolts, and nuts. There is a problem.

One object of the present invention is to provide a new type of rack assembly by supplementing the rack assembly that is complicatedly fastened by the use of various subsidiary materials.
