Description

Overhead distribution line fixing device with branching capability

[0001] The present invention relates to an overhead distribution line fixing device capable of branching wires.

[0002] Typically, overhead distribution lines (1) are installed on poles (2), and power is distributed to each user from the installed overhead distribution lines (1). As shown in Fig. 1, jumper wires (4) are supported by jumper wire fixing insulators (3), and overhead distribution lines (1) are connected through the jumper wires (4).

[0003] However, in the past, there was a problem that it was not easy to branch the electricity of the overhead distribution line (1) to an overhead transformer or underground.

[0004] Meanwhile, the jumper wire fixing member (3) is installed on the complete iron (5).

[0005] However, jumper wire fixing insulators (3) made of magnetic material are heavy and have a risk of breaking, so recently, jumper wire fixing insulators (3) made of polymer material are widely used.

[0006] However, polymers undergo photodegradation by ultraviolet light. Furthermore, when exposed to moisture while the polymer surface is contaminated with various contaminants, leakage current flows and discharge-induced tracking occurs. This tracking can cause insulation breakdown.

[0007] Therefore, when the polymer material jumper wire fixing insulator (3) is damaged, the need for replacement arises. However, in the past, replacing the polymer material jumper wire fixing insulator (3) was cumbersome and required a lot of cost.

[0008] The present invention was invented to solve the above-mentioned problem, and the problem is to provide an overhead distribution line fixing device that can easily branch electricity to an overhead transformer or underground, and that makes it convenient to replace a jumper wire fixing insulator (20) while reducing the maintenance cost of the jumper wire fixing insulator (20).

[0073]

[0074] Fig. 10 is a diagram illustrating the operation of the present invention. The operation of the present invention is described below with reference to Fig. 10.

[0075] First, in the present invention, the protective cap (40) is installed on the jumper wire fixing member (20) and the protective cap (40) is moved upward as shown in Fig. 10. At this time, the protective cap (40) is made of an elastic material, so that it is easy to move upward from the lower end of the sleeve connecting member (24).

[0076] Afterwards, the jumper wire (J) and branch wire (B) are inserted and fixed into the jumper wire connection part (32) and branch wire connection part (33) of the branch sleeve (30), respectively.

[0077] Next, when the protective cap (40) is lowered, the jumper wire (J) passes through the cut insertion hole (42) of the protective cap (40) and is placed in the jumper wire passage hole (43), so that the branch sleeve (30) is protected by the protective cap (40) as shown in Fig. 7.

[0078] Meanwhile, the replacement method of the jumper wire fixing member (20) in the present invention is described as follows.

[0079] When the jumper wire fixing insulator (20) is damaged by birds or sunlight and needs to be replaced, the worker separates the first housing (22a) and the second housing (22b) from each other to separate the polymer housing (22) from the insulator core (21).

[0080] Afterwards, the worker installs a new polymer housing (22) into the azalea core (21).

[0081] That is, the worker inserts the coupling projection (22b2a) of the first housing (22b) into the coupling groove (22a2a) of the first housing (22a), while inserting the first and second fixing grooves (22a1b, 22b1b) of the first and second housings (22a, 22b) into the first and second fixing projections (21b, 21b') of the insulator core (21), respectively.

[0082] Then, the first housing (22a) and the second housing (22b) are integrated and installed in a new polymer housing (22) on the insulator core (21).

[0083] At this time, the first housing (22a) and the second housing (22b) are stably fixed to each other, and the first and second fixing projections (21b, 21b') of the insulator core (21) are inserted into the first and second fixing grooves (22a1b, 22b1b) of the first and second housings (22a, 22b), respectively, so that the polymer housing (22) does not rotate around the insulator core (21) as its axis center.

[0084]

[0085] As described above, the present invention has a replaceable branch sleeve (30) provided at the bottom of a jumper wire fixing member (20), so that electricity can be conveniently branched to various locations such as a processing transformer or underground, and furthermore, has the effect of safely protecting the branch sleeve (30) from external factors (water, dust).

[0086] In addition, the present invention can see the effect of replacing the jumper wire fixing insulator (20) by replacing only the polymer housing (22) while the insulator core (21) is installed as is on the complete iron (10). Therefore, the present invention has the effect of allowing convenient replacement of the polymer type jumper wire fixing insulator (20) and reducing the maintenance cost of the polymer type jumper wire fixing insulator (20).

[0087]

[0088] Meanwhile, the present invention further includes a structure capable of branching electric (wire) lines in a structure for fixing overhead distribution lines, and thus the title of the present invention is defined as an overhead distribution line fixing device capable of branching wires, and the subject matter of the present invention is defined as an overhead distribution line fixing device.
