Description

Non-power-failure power distribution method using wire-changing device and bypasscable}

The present invention, in the replacement and relocation of the distribution line connected to each pole and change of transition place, by installing the wire lead mechanism in each pole, the sequential electricity between the new and old wire by the bypass cable installed on the ground or pole It is possible to replace the electric wires, replace electric poles, move electric poles and change the transition site by uninterrupting by disconnecting and connecting them. Improved workability by allowing replacement and relocation by uninterruptible power, but by the applicant of the present invention, the patent application No.0407376, "Uninterrupted power distribution method using wire transfer mechanism in electric pole" and patent registration of pre-registered It is made by applying the "Uninterruptible power distribution method of single phase line using a processing temporary line" by the arc.

In response to the surge in electric power demand, electric power facilities have been expanded in response. As the demand for electric quality of electric power users increases, the momentary power failure is also subject to civil complaints. Increasingly, uninterrupted construction methods are being performed in which the construction is performed without disconnecting the power for high quality power supply during power distribution construction.

Existing uninterrupted power distribution works consist of a transformer transformer method, a bypass cable method, and a switchgear method for construction.Bypass cable method is a cable car and a work section necessary for a cable car and work section. Equipment, mobile transformer car, live bucket truck, and air port for live work, and install bypass cable to bypass power supply, replace and relocate distribution line, and remove bypass cable again. Construction is complete.

In addition, in order to reduce the capacity of the distribution line to 5,000 KVA or less, the distribution line having a capacity of more than 5,000 KVA is less than 5,000 KVA at the time of applying the existing bypass cable method. Wastes a lot of time and labor costs when switching power loads to other distribution lines, and there is a serious problem in the system operation of an effective distribution line, and in particular, uninterrupted work on upper distribution lines of two or more lines is needed. There is a problem that construction is impossible with the current uninterrupted construction method.

Therefore, a lot of construction manpower is required for the electric power distribution work, and a lot of special high voltage connection points are created to install the bypass cable, which is standardized at 50m, in the 200 ~ 300m section. By repeating installation and dismantling frequently, waste of labor cost and damage of bypass cable are accelerated, which is a more dangerous threat to safety, and in case of safety accident or sudden power failure, to secure electricity quality at high cost. Contrary to the purpose, more civil complaints, economic loss and casualties can be brought, as well as unstable operation of the distribution line system due to excessive load transfer work and the uninterruptible method work of the upper line of the distribution line of two or more lines.

In order to solve the problems described above, the inventor of the present invention uses a wire transfer mechanism and a wire twisted pair mechanism in Jeonju to secure a working space between the old and new wires and the relocation wire in Jeonju, as in 2001 Patent Application No. 32587. The uninterrupted operation of two or more upper distribution lines without switching power is provided by providing a method to replace and relocate new power lines with an uninterruptible uninterruptible power without using a separate bypass cable. It is possible to improve the power quality and also to use the mobile transformer car construction method except when replacing the transformer, which enables safe construction at low cost, and does not interfere with pedestrians' walking or passing through the vehicle even when it is under construction. Wire transfer mechanism in an electric pole and uninterrupted power using the same Bar has devised a major laws.

However, by using the electric wire transfer mechanism and wire twisted wire mechanism in the above pole, the new wire can be replaced and relocated by separating the electric wire between the old and new wires while securing the working space between the old and new wires in Jeonju. This is a method of installing and removing wires and twisted wires for each wire to be replaced and relocated.However, by repeating the wire reworking process in the process of replacing and rewiring a large number of wires with one wire. There was a problem that a lot of time and manpower was consumed in the work.

Accordingly, the applicant of the present invention, as in Patent Registration No. 407376, in the uninterruptible power distribution method using a wire transfer mechanism in the electric pole that cuts electricity of the demolition wire without a power failure by a bypass by the connection of the installation wire and the demolition wire, Install the wires on only one side and transfer only one wire to the other side, and then replace the wires by the uninterrupted power distribution method in which the corresponding replacement wires are transferred, but the remaining replacement wires use the reverse wires as bypass cables without any separate wire process. By repeating the installation process of wire twisted wire installation, the installation wire installation, the demolition wire removal process and the uninterrupted connection method by bypass, it is necessary to install and wire the wire once and for the replacement and relocation of new and old wires. To minimize the time and manpower required for work by replacing and relocating multiple wires An uninterruptible power distribution method using a wire transfer mechanism in a pole was proposed.

However, the uninterruptible power distribution method as described above has a problem that it is difficult to separate the side of the electric wires when a building, a street lamp, a signboard, a roadside tree, or a guard tree are adjacent to each other in order to separate the electric wires on one pole on the electric pole in a downtown area. Have

In addition, if it is impossible to separate the wires to the side due to the site conditions, the existing distribution method, which is complicated and requires a lot of work time and a large number of workers, must be applied as it is.

The present invention is to solve the problems as described above, by using the "Uninterrupted power distribution method using electric wire transfer mechanism in the electric pole in accordance with the prior registration No. 10-0407376" sideways the one-phase wire on the electric pole in the metropolitan city area When it is difficult to be separated for safety due to the side of buildings, street lamps, signs, protective water, etc., in case of separation, it is impossible to separate one phase wire to the side in the field condition or for the safety of work in the field conditions. An uninterruptible power supply that completes three-phase work by sequential separation and connection of electricity one by one by using cable and wire that temporarily installs one of three phases of bypass cable and installs one phase among bypass cables. Development of "Uninterrupted Power Distribution Method Using Wire Transfer Mechanism and Bypass Cable", which enables wire replacement, Jeonju replacement and relocation work It aims to provide a more mature uninterrupted process according to the skills and preferences of workers in the field.

The present invention for achieving the object as described above, one phase of the bypass cable is installed in the ground or the main phase by using the wire transfer mechanism to the ground or main phase by using a cable and wire to temporarily transmit the phase of electricity It is made by working with new technology developed to allow uninterrupted electric wire replacement, electric pole replacement and relocation work for jijangjeon pole that completes three phase work by separate connection.

The present invention, the uninterruptible power distribution method using the wire transfer mechanism in the downtown area of the metropolitan area when the wire to be moved to the side by installing the transfer mechanism in the Jeonju when the work distance is less than the distance from the building, signboard or streetlight, etc. In some cases, the above-mentioned problems can be solved through the ground or air laying of the bypass cable according to such a case and necessary work conditions, and the selection and utilization of the uninterruptible method is widely available depending on the work proficiency and taste of the uninterruptible major. It is possible to improve safety by improving the scope of uninterruptible work and psychological stability of workers, and it is effective in reducing power outage and improving the power quality due to the expansion of work range.
