Problems solved by technology

Among them, the method of protecting insulated wires with lightning arresters cannot completely solve the problem of wire disconnection caused by lightning strikes.
If the method of overhead lightning conductors for distribution bare conductor lines is directly applied to insulated conductor lines, the cross-arm must be removed and the installation position must be lowered to leave space for the lightning conductor support. Therefore, the construction volume is large and the cost is high.

Embodiment 1

[0021] like figure 1 As shown, on the line cement pole 1, the linear lightning protection wire support is fixed at the position corresponding to the original horizontally arranged insulated wire line 1780mm cross-arm fitting 2, and the lightning protection wire support is composed of angle steel bracket 5 and two groups of installation hoops 6, 7 structure, hang the lightning protection wire suspension clamp 4 on the angle steel bracket 5, the upper and lower distances of the two sets of installation hoops 6 and 7 are kept between 400-500mm, one group of installation hoops 6 is close to the top of the cross-arm fittings 2, and the other The group installation hoop 7 is located under the cross-arm fittings 2, and the distance between the installation hoops 6 and 7 and the angle steel bracket 5 is kept at 30-35 mm to ensure that they do not overlap with the cross-arm round steel hoop 3; the height of the angle steel bracket 5 is 1900 -2000mm, to ensure that the lightning protect...

Embodiment 2

[0024] like Figure 5 , Image 6 As shown, on the line concrete pole 1, corresponding to the original horizontally arranged insulated wire line 1780mm cross-arm fittings 2 positions, the tension-resistant lightning protection wire support is fixed. , 7 constitute, the angle steel support 5 is installed with rhombus hanging plate 9, on the rhombus hanging plate 9 hanging lightning wire suspension clamp 4, two groups of installation hoops 6, 7 keep the upper and lower distance between 400-500mm, one of them One group of installation hoops 6 is close to the top of the cross-arm fittings 2, and the other set of installation hoops 7 is located below the cross-arm fittings 2. A distance of 30-35mm is maintained between the installation hoops 6 and 7 and the angle steel bracket 5 to ensure that they do not interfere with the cross-arm fittings 2. The round steel hoop 3` overlaps; the height of the angle steel support 5 is 1900-2000mm, so as to ensure that the lightning protection an...

Abstract

The invention discloses a method for mounting overhead ground wire on horizontally-arranged 10KV insulated wire lines and a lightning arrester support, which can reduce the lighting striking rate of a wire, construction amount and operation cost. A ground wire support is fixed at a position, corresponding to the position of 1,780mm cross beam hardware of an original horizontally-arranged insulator wire line, on a line cement post. The ground wire support is comprised of a steel angle support and two sets of mounting loops; the up and down distance between the two sets of mounting loops is between 400 and 500 millimeters; one set of mounting loops are close to the upper side of the cross beam hardware, while the other set of mounting loops are positioned below the cross beam hardware; the distances between the mounting loops and the steel angle support are kept between 30 and 35 millimeters, so that the mounting loops cannot be overlapped with a cross beam round steel loop nor an inserting bolt; and the height of the steel angle support is kept between 1,90 and 2,000 millimeters, so that the lighting protection angle of a steel strand is between 29 and 33 degrees.

Description

Technical field: [0001] The invention relates to a method for installing an overhead lightning protection line on a horizontally arranged 10KV insulated line circuit and a support for the lightning arrester. Background technique: [0002] There are two ways for power lines to prevent lightning: 1. Overhead lightning protection wires are generally installed on the top of the transmission line tower or the top of the cement pole of the distribution bare wire line to prevent the bare wire from being subjected to lightning. 2. The insulated wire line adopts the method of connecting various lightning arrester equipment to guide the lightning current. Among them, the method of protecting insulated wires with lightning arresters cannot completely solve the problem of wire disconnection caused by lightning strikes. If directly apply the method of the overhead lightning conductor of the distribution bare wire line to the insulated conductor line, it is necessary to remove the cross ...
