BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-

The present invention relates to a connection insulator structure of an extra high voltage distribution machined wire in the field of distribution technology, and more particularly, to a connecting insulator structure of a high voltage distribution distribution wire which can be installed relatively easily and stably on the upper end of the insulator main body, The present invention also relates to a connection insulator structure of a high-voltage power distribution processing wire so as to be smoothly replaced with an inspection of the insulator main body.

Generally, electric power generated by a power plant is supplied to a demanding place of industry or each household through a substation through a high-voltage transmission / distribution line. A transmission / distribution line for supplying electricity from a power plant to a substation is made up of a steel tower, Or shape depending on voltage or terrain.

The steel tower usually supports two wires of three phases, ie six wires, and the distance between the towers is about 20 ~ 30m. The electric wires installed on the tower are determined by the electric equipment technology from the ground.

However, when a railway crosses a river or a deep valley, the tension of the wire increases as the span becomes longer. Therefore, a steel tower with a stronger structure is required.

In this case, the transmission / distribution line is normally installed at a high position, so that it can be managed relatively safely. However, when a crane, an excavator, a ladder or the like is used, a direct impact may be applied to the transmission / distribution line due to carelessness.

When the strong shock is applied to the transmission and distribution line through the insulation insulator, the insulation between the insulation insulator and the transmission and distribution line is broken and the connection is released or the transmission and distribution line is crashed and the transmission and distribution line is severely broken Electric shock accidents may occur.

As a conventional technique which partially improves such a problem, Korean Patent Registration No. 10-1365654 (Feb. 24, 2014) discloses a connection plug of an extra-high voltage distribution processing wire.

However, since the insulator main body supports the first cushioning member, there is a problem that it is difficult to smoothly replace the insulator main body with the check of the insulator main body.

In addition, when the insulator main body is separated from the main body, detachment of the insulator main body from the first cushion member can not be easily performed only by detaching the fixing bolts, and it is difficult to draw in the new insulator main body with the first cushion member .
