Description

Three-phase wire insulation fixing bracket

technical field

The invention relates to a tool used for the operation of the live hanging end of a 10 kV long line (trunk line) at a 60°-90° corner, especially a three-phase wire insulation fixing bracket.

Background technique

Now, with the continuous development of the city, some newly built areas require supporting installation of power equipment. In some cases, existing wires need to be extended into new areas. Among them, one of the more common operations is the 10 kV long line (trunk line) 60°~90° corner upper line live hanging end operation. This operation extends the line that was originally a right-angle turn to a branch in a straight line. Since it is a live operation, it is necessary to absolutely avoid contact between wires during the operation and cause a short circuit. Existing methods require multiple elevated vehicles and multiple workers to work together to set up the newly extended lines. This method is very costly, but its efficiency is very low, and it is increasingly unsuitable for the work tasks that are now increasing rapidly with urban development.

Contents of the invention

The technical problem to be solved by the present invention is to provide a three-phase wire insulation and fixing bracket, which can adopt a simple and practical structure, and reduce the workload and cost of the 60°-90° corner of the upper line of the 10 kV long line (trunk line). .

In order to solve the above-mentioned technical problems, the technical scheme of the three-phase wire insulation and fixing support of the present invention is to include a support base, a support platform, a support diagonal brace, a support iron, a support stand, a support brace and a support bar, the support base and The support irons are all fixed on the utility poles, the support irons are located directly below the support base, the support platform is rectangular, a short side of the support platform is connected to the support base, and the support The platform is in a horizontal posture, one end of the support brace is connected to the support iron, and the other end is connected to the end of the support platform away from the utility pole; the support stand is installed vertically upward on the side of the support platform away from the utility pole One end, one end of the support brace is connected to the end of the support platform close to the utility pole, the other end of the support brace is connected to the upper end of the support stand, and the upper end of the support stand is also provided with a support A horizontal bar, the horizontal bar of the bracket is provided with grooves for accommodating electric wires.

The structure of the invention is simple and firm, greatly reduces the workload of the 10 kV long line (trunk line) at the 60°-90° corner of the upper line to hang the end of the live line, reduces the number of workers participating in the operation and the equipment used, and greatly reduces the cost.

Detailed ways

The present invention provides a three-phase wire insulation fixing bracket, as shown in Figures 1 to 8, comprising a bracket base 1, a bracket platform 2, a bracket brace 3, a brace iron 4, a bracket stand 5, a bracket brace 6 and Support bar 7, the support base 1 and the support iron 4 are all fixed on the utility pole 8, the support iron 4 is located directly below the support base 1, the support platform 2 is rectangular, and the support A short side of the platform 2 is connected to the support base 1, the support platform 2 is in a horizontal posture, one end of the support brace 3 is connected to the support iron 4, and the other end is connected to the support platform 2 away from the One end of the utility pole; the support stand 5 is installed vertically upward on the end of the support platform 2 away from the utility pole, and one end of the support brace 6 is connected to the end of the support platform 2 close to the utility pole, and the support The other end of the brace 6 is connected to the upper end of the support stand 5, and the upper end of the support stand 5 is also provided with a support bar 7, and the support bar 7 is provided with a groove 9 for accommodating electric wires.

The support platform 2 is connected to the support iron 4 through two support braces 3 , and the two support braces 3 are installed on both sides of the support platform 2 respectively.

The support platform 2 is connected to the support stand 5 through two support braces 6 , and the two support braces 6 are respectively installed on both sides of the support platform 2 .

Three grooves 9 for accommodating electric wires are arranged on the bracket bar 7 .

As shown in Figure 9, when carrying out the 10 kV long line (trunk line) 60 ° ~ 90 ° corner upper line live hanging end operation, use the insulator 9 to cover the wires D and F, and then install the drain wire under the wire, said Drainage line connects line A and line D, then fixes the support base 1 on the utility pole, installs the support platform 2 on the support base 1, and then installs the supporting iron 4 and the support under the support base 1 Diagonal brace 3, install support vertical frame 5 and support brace 6 on support platform 2 afterwards, install support horizontal bar 7 on support vertical frame 5 at last. After the three-phase wire insulating and fixing support is installed, the extended wire is clamped in the groove on the bracket bar 7, and the extended wire is connected to the original wire on the utility pole, as shown in Figure 9, the wire H is connected to line A, line I is connected to line B, and line J is connected to line C. After the other end of the extended wire is installed so that the wire does not sag, the three-phase wire insulation fixing bracket is removed.

In summary, the structure of the present invention is simple and firm, which greatly reduces the workload of the 10 kV long line (main line) at the 60° to 90° corner of the upper line to hang the end of the live line, reduces the number of workers participating in the operation and the equipment used, and greatly Reduced costs.
