Description

Electric wire processing device for distribution line and solar power generation line, and overhead line processed using the same

The present invention relates to a wire processing apparatus and an overhead line, and more specifically, cutting the wire used for solar power generation and distribution line construction to a required length and at the same time spaced a certain distance from both sides of the cut portion to give a sheath to the sheath , Pull the wire outward from the cut part to expose some of the core wire, connect the wire by heat-sealing the covered part from which the core wire was partially discharged, and then rotate the heat-sealed part to wrap the end of the core wire and then return the reel. It relates to a wire processing device for a distribution line and a photovoltaic power generation line that is continuously wound and stored in the present invention, and an overhead line processed using the same.

In general, an overhead line refers to a line from a photovoltaic module to a junction panel, an inverter, and a low-voltage panel along the connection of electric wires to the distribution line and the photovoltaic lead-in line.

In addition, the photovoltaic module of the photovoltaic device is a form in which solar cells are connected vertically and horizontally, and electricity produced from individual solar cells is collected at the same time in the module. Solar power generation is divided into fixed type and tracking type BIPV.

In addition, the principle of photovoltaic power generation using such a photovoltaic module is carried out by the photovoltaic effect, and when n-type doping on silicon crystal and irradiating sunlight to a pn junction solar cell, the photovoltaic energy is used to destroy electron holes. An electromotive force is generated, which is called the photovoltaic effect. As many solar panels are connected in series and parallel as desired, the desired power is produced and used. It is called a grid-connected solar power system. When this grid is connected, it is joined with an overhead power line.

In particular, DC power produced by the solar module of the photovoltaic device is converted into AC power through an inverter device and then connected to the grid through an overhead wire.

Such grid-connected photovoltaic power generation is affected by the transformer capacity of the substation.

Such grid-connected power generation facilities, such as private vehicles, are related to cutting and connecting electric wires in distribution lines, which is consistent with the present invention.

The electric wires required for such photovoltaic power generation and line construction have a problem in that the operator cuts the electric wires to the required length one by one, strips the coating on both ends, and then connects them to the connector, consuming a lot of time for the work.

In order to solve this problem, the wire is cut to the length required by the factory, and the wire harness bundled by length is delivered to the construction site by stripping the coverings at both ends, and the operator collects the necessary wires and performs the work.

However, since such a wire harness is cut to a certain length and tied to the same length, when the length is relatively short, it is difficult to roll it into a roll shape, so storage or transport is difficult.

The present invention is to solve the above problems, and at the same time as cutting the electric wire used for photovoltaic power generation and distribution line construction to the required length, at the same time spaced a certain distance from both sides of the cutting site to give a sheath to the sheath, and then to the cutting site Pull the wires outward on the basis of , partially exposing the core wires, heat-seal the covered parts where the core wires are partially discharged to connect the wires, rotate the heat-sealed parts to wrap the ends of the core wires, and then connect them continuously on the recovery reel. An object of the present invention is to provide a wire processing device for a distribution line and a photovoltaic power generation line to be wound and stored, and an overhead line processed using the same.

In addition, the present invention reduces the working time by allowing a worker at a construction site to quickly use an electric wire cut to a certain length by cutting the exposed part of the core wire while unwinding the wire from the roll or pulling the core wire out of the sheath by applying force. Another object of the present invention is to provide a wire processing device for a distribution line and a photovoltaic power generation line, and an overhead line processed using the same.
