Description

Indirect live line extension arm and method for securing a safe distance for indirect live line work using the same, indirect live line uninterrupted power distribution method based on the method for securing a safe distance for indirect live line work.

[0001] The present invention relates to an indirect live-line uninterruptible power distribution work based on securing a safety distance for indirect live-line work and a method for securing the safety distance for the work, and more specifically, to an indirect live-line uninterruptible power distribution work, which enables simple and safe work such as changing a pole, replacing a steel bar, replacing a suspension insulator, replacing an LP insulator, adjusting the angle, installing and removing LA, installing a new pole, replacing a pole, installing and removing protective gear, replacing a jumper wire, replacing a wire, inspecting each line, and installing and removing a switch, for one or more distribution lines and their upper distribution lines, while securing a sufficient indirect live-line work safety distance for the work, and a method for securing a safety distance for indirect live-line work using the same, and an indirect live-line uninterruptible power distribution work method based on the method for securing a safety distance for the work.

[0002]

[0003] In response to the recent surge in electricity demand, power facilities are continuously being expanded, and as power users' demands for electricity quality are increasing, even momentary power outages are becoming the subject of public complaints, leading to an increase in collective actions and lawsuits by power users seeking compensation. Therefore, uninterruptible power construction methods are being implemented to ensure a high-quality power supply during power distribution construction without cutting off the power.

[0004] Meanwhile, the existing distribution construction using the uninterruptible power method consists of the mobile transformer car construction method, the bypass cable construction method, and the construction switch construction method, but the bypass jumper cable construction method is equipped with a cable car, cables required for the work section, construction switches, a mobile transformer car, a live-line bucket truck, and all pneumatic tools for live-line work, and bypasses the power supply by installing bypass cables, etc. through direct live-line work, and then replaces the distribution lines and replaces and relocates the wires, and then removes the bypass cables, etc. through direct live-line work to complete the distribution construction.

[0005] In addition, for distribution lines with a power line electric capacity exceeding 5,000 KW, when the existing bypass jumper cable method is applied, since the allowable capacity of the cable for the existing cable method is 5,000 KW or less, a lot of time and labor costs are wasted in transferring the power load to other distribution lines to reduce the capacity of the distribution line to 5,000 KW or less, and there are serious problems with the effective operation of the distribution line system.

[0006] Accordingly, indirect live-line work, which involves using insulated tools such as live-line work sticks to work indirectly, is being utilized recently to solve the above-mentioned problems.

[0007] However, although the general indirect live-line work described above can be very useful for work on a single line of a distribution line, in the case of distribution lines with more than one upper and lower line, there is no suitable work method because the safety clearance for indirect live-line work is not secured for performing work on the upper distribution line.

[0008] Therefore, uninterrupted work is being done by applying the bypass cable method, which not only requires 3 to 10 times more construction costs but also causes frequent accidents in construction switches.

[0132] To this end, the joint (100) is formed in a tubular shape that is open forward so that it can be joined to the complete iron, and is preferably formed in a square tubular shape.

[0133] The above extension part (200) is configured to be extended to the rear end of the connecting part (100) when forming the indirect live wire extension arm (1) of the present invention, and can preferably be configured to be extendable through the connecting configuration.

[0134] At this time, the extension part (200) has a square tube shape like a normal iron, and a plurality of mounting holes (210) are formed vertically or horizontally through the middle part to enable mounting of a ball screw or the like for installing an LP insulator or a suspension insulator.

[0135] The above-mentioned mounting means (300) is formed on the connecting portion (100) to form the indirect live wire extension arm (1) of the present invention, and is configured to provide a fastening force when the connecting portion (100) is connected to the connecting portion, thereby enabling stable mounting and fixation.

[0136] To this end, the mounting means (300) is first configured with a support plate (310), and the support plate (310) is configured in a plate shape having a front-back length. In the present invention, the support plates (310) may be configured to form a single or symmetrically spaced pair according to the first to third embodiments of the connecting portion (100) described below.

[0137] At this time, the support plate (310) is configured with spacers (311) protruding in all directions on its surface, and the support plate (310) is configured with a guide pin (312) protruding in the center of the rear end thereof, and a spring support pin (313) is formed protruding in the middle, and a lever guide hole (314) in the form of a horizontal hole in the front-back direction is formed through the rear side of the spring support pin (313). When the support plates (310) are configured as a pair, the spacers (311), the guide pins (312), and the spring support pins (313) can be connected to each other so as to be spaced apart from each other.

[0138] In addition, the mounting means (300) is configured with an operating plate (320) using the support plate (310) as a guide, and the operating plate (320) is configured to be accommodated between the spacers (311) and to slide back and forth.

[0139] At this time, the operating plate (320) is provided with a protruding catch (321) to prevent the unfolding of the fastener (330) (330') described later at the tip thereof.

[0140] And, in the middle part of the front side of the operating plate (320), a horizontal hole-shaped spring guide groove (322) is formed through which the spring support pin (313) passes, and a spring (323) is elastically installed between the spring support pin (313) and the spring guide groove (322), thereby providing forward movement force to the operating plate (320).

[0141] In addition, the operating plate (320) is configured such that the guide pin guide groove (324) is opened rearward so that the guide pin (312) is received and guided at the rear end, thereby enabling stable sliding operation of the operating plate (320).

[0142] In addition, the mounting means (300) is configured with a pair of fastening members (330) (330') on both sides in the width direction that are deployed or folded by sliding the operating plate (320) to provide fastening force to the complete iron.

[0143] `At this time, each fastener (330)(330') is configured such that its rear is connected to the front side of the support plate (310) by an axis (331) and rotates in opposite directions in the width direction, and each is configured such that an opening spring (332) is elastically installed to have elasticity for the front side to unfold.

[0144] And, in each fastener (330)(330'), a pin fixing groove (333) in the shape of a semicircular groove is formed in the front facing each other, and a catching groove (334) is formed in the rear facing each other to catch the catching portion (321) of the operating plate (320).

[0145] At this time, in the present invention, it is preferable that the catch groove (334) be configured to form a step, such that the front is narrow and the rear is wide, so that when the catch protrusion (321) of the operating plate (320) is positioned in front of the catch groove (334), the opening spring (332) is compressed, so that the front of the fastening opening (330) (330') is folded and the pin fixing groove (333) is closed, and when it is positioned in the rear of the catch groove (334), the front of the fastening opening (330) (330') is expanded and the pin fixing groove (333) is opened by the elasticity of the opening spring (332).

[0146] Additionally, the mounting means (300) is configured with an operating lever (340) that controls the sliding movement of the operating plate (320).

[0149] That is, the mounting means (300) moves together with the operating plate (320) when the operating lever (340) is retracted rearward with reference to FIG. 10, and at this time, the engaging portion (321) of the operating plate (320) moves rearward of the engaging groove (334), and at the same time, the fastener (330)(330') rotates around the axis (331) and unfolds forward by the elasticity of the opening spring (332) to open the pin fixing groove (333), and when the retracting force of the operating lever (340) is released, the pin is caught on the step of the engaging groove (334) configured in a step.

[0150] Afterwards, when a bolt for fixing a conventional iron, a fixing pin of an insulator, a ball screw fixing pin (cotter pin), etc., installed in the open pin fixing groove (333) is received in the pin fixing groove (333) and the pin fixing groove (333) is pressed, the fastening member (330)(330') opens to a predetermined extent and the operating plate (320) moves forward by the return elasticity of the spring (323) and the catch (321) is inserted into the inside of the catch groove (334). At this time, the pin fixing groove (333) is closed to fasten and fix the bolt for fixing a conventional iron, a fixing pin of an insulator, a ball screw fixing pin (cotter pin), etc., by hooking them.

[0151] Meanwhile, the indirect live wire extension arm (1) of the present invention can be configured to enable various extension applications, such as pin poles, built-in poles, or single-type built-in built-in poles of distribution lines, through various embodiments of the above-mentioned connecting portion (100).

[0152] First, the coupling part (100) according to the first embodiment can be configured as a coupling part (110) for pins that can be applied to the complete removal of pins of a distribution line.

[0153] To this end, referring to FIGS. 1 and 2, the pin-type connecting portion (110) is first configured to form a hollow insertion space (111) that is open forward and has a front end so that a pin-type screw can be inserted.

[0154] And, on the upper surface, a guide groove (112) is formed to allow the iron to advance into the iron insertion space (111) by being opened forward.

[0155] And on both sides, a pair of fixed pin guide grooves (113) are formed so that the middle part is opened forward to accommodate fixed pins (not shown in the drawing) installed as an accessory to the pin holder.

[0156] And, when installing the pin-type connecting part (110) with the fixed pin guide groove (113) as the center, a pin hooking part (114) is formed on the upper part of both sides so that it can be hooked onto the fixed pin installed as mentioned above by protruding forward and having a predetermined downward slope.

[0157] And on the bottom surface, a work hole (115) is formed through which tools, etc. can enter so as to be connected to the above-mentioned full-steel insertion space (111).

[0160] And the above operating lever (340) is fixedly mounted on the operating plate (320) so as to pass through the lever through hole (118) and the lever guide hole (314).

[0161] Accordingly, when configuring the configuration of the connecting part (100) as the pin-type connecting part (110) as described above, with reference to FIG. 11, a separate fixing pin (25) for installing the indirect live wire extension arm (1) of the present invention can be installed horizontally through the pin-type connecting part (21a).

[0162] And, when connected to the pin-length fitting (21a) through the pin-length fitting joint (110), the pin-length fitting (21a) is horizontally connected so that the pin-length fitting (21a) is received in the pin-length fitting guide groove (112) formed at the top while the upper part of the fixed pin (25) is hooked and supported by the pin hook (114).

[0163] Accordingly, the fixed pin (25) is inserted and hooked into the fixed pin guide groove (113), and the end of the pin-length-use wrench (21a) is inserted into the wrench insertion space (111). At this time, interference with the LP insulator (52) is prevented through the wrench guide groove (112) cut out at the top, and the indirect live wire wrench extension arm (1) of the present invention can be coupled to the pin-length-use wrench (21a) through the pin-length-use connecting portion (110). When coupled in this way, the extension portion (200) protrudes horizontally, enabling the length of the pin-length-use wrench (21a) to be extended.

[0164] Meanwhile, as described above, when the pin-type joint (110) is coupled, the fastening and fixing of the mounting means (300) is possible by hooking the fixing pin (25) to the fastening hole (330) (330') through the unfolding or folding operation of the fastening hole (330) (330') by operating the operating lever (340) using the live-line work stick as described above.

[0165] In addition, the coupling part (100) according to the second embodiment can be configured as a coupling part (120) for built-in poles applicable to the complete installation of built-in poles of distribution lines.

[0167] And, on the upper and lower surfaces, a pin guide groove (122) is formed on which a cotter pin of a ball shackle (not shown in the drawing) is guided to install a suspension insulator on a built-in main body by being cut out to be open forward.

[0168] And on both sides, a pair of bolt guide grooves (123) are formed so that the middle part is opened forward to accommodate bolts (not shown in the drawing) for connecting the inner main body to each other.

[0169] And, on one side, a mounting means housing (125) for configuring the mounting means (300) is further configured. At this time, the mounting means housing (125) is opened forward, and a bolt guide groove (126) corresponding to the bolt guide groove (123) is formed at the front end, and a lever through hole (127) is formed through the middle portion to correspond to the lever guide hole (314) of the support plate (310).

[0170] And on the other side, a slanted reinforcing member (128) is protruded to enable insertion and installation by passing through the inside of a conventionally folded ball screw.

[0171] Accordingly, the mounting means (300) is fixedly mounted on the inner surface of the mounting means housing (125) with the support plate (310) so that the fastening hole (330)(330') is positioned in the front, and one end of the opening spring (332) is elastically installed at the rear of the fastening hole (330)(330') and the other end is supported on the side of the mounting means housing (125) so that the fastening hole (330)(330') has elasticity that opens.

[0172] And the above operating lever (340) is fixedly mounted on the operating plate (320) so as to pass through the lever through hole (127) and the lever guide hole (314).

[0174] At this time, the cotter pin (26a) of the ball screw (26) is received and guided in the pin guide groove (122) formed on the upper and lower sides of the inner main joint (120), the inclined reinforcement portion (128) formed on the other side is inserted and supported into the inside of the ball screw (26), and the M bolt (27) connecting the inner main screws (21b) on both sides is received in the bolt guide groove (123) and the bolt guide groove (126), so that installation is possible without interference with the ball screw (26) and the M bolt (27).

[0175] Accordingly, the indirect live wire extension arm (1) of the present invention can be connected to the built-in cast iron (21b) through the built-in cast iron connecting portion (120), and when connected in this manner, the extension portion (200) protrudes horizontally, enabling the length of the built-in cast iron (21b) to be extended.

[0176] Meanwhile, as described above, when the built-in main joint (120) is coupled, the fastening and fixing of the mounting means (300) is possible by hooking the cotter pin (26a) to the fastening hole (330) (330') through the unfolding or folding operation of the fastening hole (330) (330') by operating the operating lever (340) using the live-line work stick as described above.

[0177] In addition, the coupling part (100) according to the third embodiment can be configured as a single built-in main coupling part (130) applicable to a single built-in complete steel of a distribution line.

[0178] To this end, referring to FIGS. 5 and 6, the single-inner-type connecting member (130) is first configured to have a diameter smaller than the diameter of the single-type inner-type steel plate so that it can be inserted into the single-type inner-type steel plate.

[0179] And, in the center of the upper and lower surfaces, a pin guide groove (131) is formed on which a cotter pin of a ball shackle (not shown in the drawing) is guided to install a suspension insulator in a single-type built-in shackle by being cut out to be open forward.

[0180] And on the upper surface, a lever through hole (132) corresponding to the lever guide hole (314) is formed through the rear of the pin guide groove (131).

[0182] And the above operating lever (340) is fixedly mounted on the operating plate (320) so as to pass through the lever through hole (132) and the lever guide hole (314).

[0183] Accordingly, when configuring the configuration of the connecting part (100) as described above with a single internal main connecting part (130), refer to FIG. 13 and connect it to the single internal main connecting part (130) through the single internal main connecting part, but insert the single internal main connecting part (130) horizontally into the end of the single internal main connecting part (21c).

[0184] At this time, the single built-in main joint (130) is guided by the cotter pin (26a) of the ball screw (26) in the pin guide groove (131) formed on the upper and lower portions thereof.

[0186] Meanwhile, as described above, when the single built-in main joint (130) is coupled, the fastening and fixing of the mounting means (300) is made possible by hooking the cotter pin (26a) to the fastening hole (330) (330') through the unfolding or folding operation of the fastening hole (330) (330') by operating the operating lever (340) using the live-line work stick as described above.

[0187] At this time, it is desirable to perform the extension work with the operating lever (340) facing downward when extending using the single built-in main joint (130) of the present invention, thereby making it easy to operate the live work stick.

[0188] Hereinafter, a method for securing a safety distance for indirect live line work using the indirect live line extension arm of the present invention having the above-mentioned configuration will be examined.
