Description

Electric wire transfer mechanism in electric pole and uninterruptible power distribution method using same {wire-changing device inside of electric pole and non-power-failure power distribution method}

The present invention in the replacement and relocation of the distribution line connected to each pole and change of transition site, by using the wire transfer mechanism installed in each pole without the use of a separate bypass cable to bypass the old and new wires The present invention relates to a wire transfer mechanism that enables uninterrupted electric wire replacement, electric pole replacement, electric pole relocation, and change of location by uninterrupted electrical connection by means of sequential electricity.

As the demand for electric power increases, electric power facilities have been expanded in response. As the demand level of electric power 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 work is composed of a transformer transformer method, a bypass (By-pass) cable method, a switchgear method for construction as shown in Figure 9, the bypass cable method is a cable car and work section Equipped with necessary cables, construction switchgear, mobile transformer car, live basket truck, and air port for live work, and install bypass cable to bypass power supply, replace and relocate distribution line, and then bypass cable again. Dismantling the power distribution work is completed.

In addition, in order to reduce the capacity of the distribution line to 5,000 KW or less since the allowable capacity of the cable for the existing cable method is 5,000 KW or less in the work where the existing bypass cable method is applied when the distribution line electric capacity exceeds 5,000 KW. Waste time and labor costs in switching power loads to other distribution lines, and there are serious problems in the system operation of effective distribution lines, and in particular, the distribution lines of two or more lines above and below one electric pole are currently in operation. There is a problem that can not be built by 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 bypass cables, which are standardized at 50m, in the range of 200 ~ 300m. It is necessary to repeat the installation and dismantling frequently, which wastes a lot of labor costs and damages the bypass cable, which makes it a more dangerous threat, and if there is a safety accident or an unexpected power failure, to secure electricity quality at a high cost. It is not only for the purpose and can bring more civil complaints, economic loss and casualties, but also the unstable operation of the uninterrupted distribution line system and the uninterrupted construction of the upper line of the two or more distribution lines due to excessive load switching.

The present invention eliminates these problems, by using a wire transfer mechanism and wire twisting device in the pole pole to secure the working space between the old and new wire replacement and relocation wire in the electric pole and separate bypass by the electrical connection between the old and new wires Provides a method for replacing and relocating new power lines with uninterruptible power outage without using cables, enabling uninterrupted work on top distribution lines of two or more lines without switching power loads. It is an object of the present invention to enable safe construction at low cost as a new technology that does not use the vehicle construction method other than transformer replacement, and does not interfere with the pedestrian walking or passing through the vehicle by the bypass cable even during construction.

The uninterruptible power distribution method using the wire wire mechanism as described above is described as follows.

First, the distribution method is as shown in Fig. 1, and the wire wire mechanism installation process for installing the wire lead mechanisms for human and internal pins for pins and pins ,

Wire transfer process to move the demolition cable to other spaces of the complete and complete extension means by the wire transfer mechanism to secure the space for replacement and relocation cables;

To protect live wires of wires that have been wired and to install wire stranding mechanisms on the pin insulators;

A wire installation process for installing new wires by performing twisted wires and long wires on the wire installation space secured and secured to the live wire, and the twisted pair mechanism installed on the upper part of the LP insulator

The process of maintaining the space between new and old wires to ensure the safety by preventing contact between the installation wire and the demolition wire during wire stranding work;

An uninterruptible electrical separation process that connects the installation wire and the demolition wire to each other and bypasses the electricity of the demolition wire

It is a demolition process to remove electric wires that are cut off from electricity.

At this time, such as changing the transition place, such as when there is no wire stranding process in the existing poles, it is necessary to skip the respective processes that are not necessary.

Such a process will be described in detail by way of examples.

In the installation process of the electric wire lead installation mechanism, the electric wire lead mechanism is installed according to the pole type of each pole.

For example, a human race line and a built-in column, in which a suspension insulator 2 is installed and the wires are connected to the suspension insulator 2, completes the wire transfer mechanism for the human race and the embedded line as shown in FIG. Insert the support plate (11) (11 ') into the finishing (1) to be fixed with a fixing bolt 12,

After rotating the shaft bar 32 and the shaft pipe 33 supported by the clamp 34 to the axial point by rotating in the other direction by the shaft rotation means 30 to adjust the required angle to the work, the inner surface of the shaft pipe 33 The spline 35s of the position fixing tool and the position fixing tool 35 on which the flange 35f is formed are fitted with respect to the axial pipe spline 33s formed in the upper and lower arm bodies. The length (height) of 23 and 23 'is adjusted by fixing the lower arm body 23' with the arm fixing clamp 31c, and the upper arm body 23 by adjusting the height adjusting clamp 24. To do it,

It is installed in the middle of humanism and internalism, and the pin insulator which has the LP insulator (3) installed in the finish (1) to allow the wire to pass through is fixed in the pin holder. It is fixed to the complete by the support plate 11 and the fixing bolt 12, which means (10).

In addition, when it is necessary to install the electric wire mechanism which has been electric wired according to the position of the electric wire and the working conditions outside, the supporting plate 41 for the completion of the extension means 40 as shown in FIG. And the insertion hole 42 and the pinned pins 45 and 45 ', which are coupled with the complete and protrude outward from the extension arm 43 and the finished 1 so that the wire is installed to install the wire. Safe and convenient operation is possible by securing space.

In this way, after the wire wire mechanism is installed, the wire wire process is performed by removing the dead and clamps from the suspension insulator 2 of the humanitarian and internal poles. After moving the live joist, the jumper wire is inserted into the insulated twisted pair rollers 21 and 21 ', and the wire to be demolished and moved is fixed while being moved to another position in the pole as shown in FIG. 7A.

At this time, since the rod 32 and the clamp 34 can be fixed or separated from each other, the position can be changed so that the left and right lengths can be adjusted, and even if the width of the finish is slightly different, the shaft rotation means 30 and the existing suspension The insertion length of the two arm bodies 23 (23 ') by the jumper arm fixing clamp 24 and the arm fixing clamp 31c formed on the arm body 23 of the rotating arm means according to the distance from the insulator 2 The length can be adjusted by moving and fixing.

In addition, in the case of pin length, as shown in Fig. 7B, the wires fixed to the side of the LP insulator are moved into the rollers 21 and 21 'by the expandable rollers 21 on the upper end of the arm body 23' of the lead wire mechanism. After the wires are accommodated, the binding of the LP insulator is released, and the shaft rotation means 30 is rotated to the other side. As the wires mounted on the LP insulator are moved to the other side, the installation space of the new wire is generated.

In addition, among the three wires installed in the pole, the center of the wire is located in the narrower working space, so it is necessary to move the outer wire to the outside of the complete line to secure the working space.

At this time, as shown in FIG. 7c, the extension arm 43 is coupled to the end of the arm by means of the support plate 41 and the insertion port 42, and the extension arm 43 is installed to protrude outward from the arm. In this case, after the wire is installed in the same manner as the wire installation means, the outside of the wire can be moved to the outside in the same way.

After the cable is completed, the live protective wire should be put on the live wire demolition cable.If there is a branch line or a transformer in the work area, use a jumper bypass cable or COS bypass cable to wire the wire to be dismantled. Bypass connection is possible, and a live protective cover is installed.

After the live wire protection process is completed, new wires are installed in the wire installation space on the upper part of the pin-jangju LP insulator secured by the wires being transferred, using the wire twisting mechanism as shown in FIG. Doing twisted pair work,

When installing the wire twisted pair mechanism on the LP insulator, first open the pad 71, which is the insulator coupling means 70 at the lower side, centering on the rear axis point, and insert it into the upper groove of the LP insulator. By tightening the clamping clamp 72 of the wire connecting roller can be firmly coupled to the upper portion of the LP insulator, the pad 71 can be made of a soft plastic material of the insulating material can block the current of the wire, when combined The LP insulator can be prevented from being damaged.

In this way, with respect to the wire stranded roller installed on the upper part of the LP insulator, first open the L-shaped roller support 81, which is the opening and closing means 80, to the left and right to insert the wire for installation in the state where the inner space is opened. The upper portion of the vertical roller 82 of the L-shaped roller support 81 is rotated to the upper side of the LP insulator by the insulator coupling means 70, and the L-shaped roller support 81 is rotated inward. Locking is supported by the spring force by fitting into the engaging groove 64 of the 61 so that the electric wire is trapped between the rollers as shown in Fig. 7d and the lower roller 84 of the L-shaped roller support 81 Rotating around the axial point as the projecting upwards upwards to raise the support wire 94 in the upper portion.

Therefore, since the wire is interviewed on the roller while being separated from the LP insulator, the movement is smooth and free, and when the wire is moved for the stranded or long wire of the wire, the operation is convenient and easy, and the wire or insulator surface can be prevented from being damaged.

When the stranded wire is in a state where the tension is not adjusted, the gap between the new and old wires is irregular during the stranded wire work. As a result, the wire clamp 92 is fastened by tightening on the oral wire, and the new wire is inserted into the stranded wire roller 91 to maintain the wire spacing as much as the spacing bar 90, thereby achieving safe work.

In this way, the stranded wire is pulled to the tension insulator with the appropriate tension, and the wire is fixed to the dead end clamp of each suspension insulator. Complete the process.

After the installation of the new wire is completed, bypass the live wire demolition wire which is still alive and the new wire, and if there is a branch line or transformer in between, connect it to the new wire. Remove the jumper bypass cable and the COS bypass cable while supplying uninterrupted power.

When the preparation is completed, the uninterruptible electrical separation process is completed, in which the wire to be removed is completely disconnected from the power source to cut off electricity.

Since the demolition wire that is cut off from electricity does not pass through electricity, a safe operation is possible, and as shown in FIG. 8, the arm body 23 of the wire twist mechanism is released by unwinding the clamp 24 to alleviate the tension of the wire. Afterwards, it is possible to safely and easily dismantle the safety rope and the tensioner winch for distribution at a lower position than the newly live wire.

When the wire is removed, all the wires and wires installed in Jeonju are removed, so that the uninterrupted wire replacement, Jeonju replacement, Jeonju relocation, and the change of transition site are completed.

As described above, in the present invention, in the replacement and relocation of the distribution lines connected to each pole, and the change of the transition paper, the wires to be replaced and relocated in the live state are moved by using the wire transfer mechanism in the pole, and the new wire is replaced in place. After the installation, bypass current is required without the need for a separate bypass cable, so it is very safe and simple to carry out wire replacement, electric pole replacement, electric pole relocation and transit change work in uninterrupted state. It is possible to operate the system efficiently and stably by not overloading the large-capacity distribution line, and to perform uninterrupted work on the upper line of two or more distribution lines. In addition, the transformer transformer method can be applied only when necessary to replace the transformer. While being a cost-saving miracle is effective to minimize the complaints do not interfere due to cable installation with respect to pedestrians or passing vehicles.
