Abstract
Description
Technical Field
[0001] This utility model provides an anti-galling support device for 10kV distribution lines, belonging to the field of power equipment technology. Background Technology
[0002] With the upgrading and transformation of distribution network lines, urban 10kV lines are gradually being converted to cables. However, most rural distribution network lines still rely on bare conductors. In severe cold weather, icing and dancing often occur on 10kV overhead bare conductors, causing air gap flashovers or wire contact, leading to phase-to-phase short circuits. In addition, during the summer and autumn, near 10kV overhead lines in forested or agricultural areas, the vegetation and vegetable gardens nearby attract large flocks of birds to the adjacent lines. The birds' movements can easily cause the conductors on those lines to sway, also resulting in phase-to-phase short circuits. Due to weather conditions and bird damage, distribution network lines experience a certain degree of dancing throughout the year, and the resulting phase-to-phase short circuits pose a serious threat to power supply reliability.
[0003] The unpredictable weather conditions and bird activity associated with galloping mean that distribution lines experience galloping to some extent throughout the year, leading to phase-to-phase short circuits and posing a serious threat to power supply reliability. To prevent galloping accidents, anti-galloping spacers are widely used. These spacers are effective in suppressing galloping, preventing conductor adhesion, and preventing wind deflection. However, in recent years, frequent defects in anti-galloping spacers have rendered them ineffective, even damaging conductors and causing line breaks, creating a situation where one aspect is insufficient to prevent galloping, posing serious safety hazards and challenges to the safe and stable operation of the power system. Furthermore, due to differences in meteorological and topographical environments and design and implementation standards, different distribution lines at the same voltage level will have structural differences, highlighting the issue of the universality of phase-to-phase spacers.

Detailed Implementation
[0016] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.
[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0018] like Figures 1 to 10 As shown, this utility model provides an anti-galling support device for 10kV distribution lines, including a support structure. The support structure includes multiple epoxy resin spacers 1, each epoxy resin spacer 1 having multiple first adjustment holes 2. The multiple first adjustment holes 2 are arranged in an array along the length direction of the epoxy resin spacer 1. The number of first adjustment holes 2 can be adjusted according to actual construction needs. In this embodiment, each epoxy resin spacer 1 has four first adjustment holes 2.
[0019] One end of each pair of epoxy resin spacers 1 is fixedly connected by an adjustment device, and the first adjustment hole 2 cooperates with the adjustment device. The other end of the multiple epoxy resin spacers 1 is fixedly connected to one end of a "T"-shaped wire clamp 5, and the other two ends of the "T"-shaped wire clamp 5 are fixedly connected to the conductor 7.
[0020] Specifically, when the support structure consists of two epoxy resin spacers 1, the corresponding first adjustment holes 2 on the two epoxy resin spacers 1 are one-to-one, the two epoxy resin spacers 1 are parallel to each other, and one end of the two epoxy resin spacers 1 is fixedly connected by an adjustment device, making the support structure as a whole straight. The adjustment device cooperates with the first adjustment holes 2, and the adjustment device includes an adjustment bolt 3. The length of the support structure composed of the two epoxy resin spacers 1 is adjusted by adjusting the relative position of the first adjustment holes 2 on the two epoxy resin spacers 1. That is, the spacing between the supported wires 7 is adjusted by adjusting the number of first adjustment holes 2 on the two epoxy resin spacers 1 that cooperate with each other.
[0021] When all the first adjustment holes 2 on the two epoxy resin spacers 1 correspond one-to-one and the two epoxy resin spacers 1 are fixedly connected by the adjustment device, the length of the support structure formed by the two epoxy resin spacers 1 is the shortest, such as Figure 1 As shown; when the two first adjustment holes 2 at the upper ends of the two epoxy resin spacers 1 cooperate with the adjustment device to fix the two epoxy resin spacers 1, that is, when the first adjustment hole 2 on the two epoxy resin spacers 1 furthest from the end of the "T"-shaped wire clamp 5 that is fixedly connected to it cooperates with the adjustment device to fix the two epoxy resin spacers 1, the length of the support structure formed by the two epoxy resin spacers 1 is the longest. In this embodiment, in order to ensure the stability of the connection of the two epoxy resin spacers 1, it is required that each epoxy resin spacer 1 has at least two first adjustment holes 2 that cooperate with the adjustment device to fix the two epoxy resin spacers 1, such as Figure 3 As shown.
[0022] The adjustment device also includes two sets of first epoxy resin clips 8, which cooperate with epoxy resin spacers 1, specifically with the epoxy resin spacers 1 located between the two sets of first epoxy resin clips 8. Multiple adjustment sections are formed on the first epoxy resin clips 8, each adjustment section including multiple second adjustment holes 9, which are arranged in a linear array. The number of second adjustment holes 9 in each adjustment section may be the same or different. In this embodiment, both adjustment sections include the same number of second adjustment holes 9, four in each case. Those skilled in the art can make adaptive adjustments according to the specific implementation environment.
[0023] When a second adjustment hole 9 on the edge of one of the three sets of adjustment parts on the first epoxy resin clip 8 corresponds to a first adjustment hole 2 at the upper end of one of the three epoxy resin spacer bars 1, the support structure is at its maximum size, such as... Figure 10As shown; when a second adjustment hole 9 near the center of the first epoxy resin clip 8 in the three sets of adjustment parts corresponds to a first adjustment hole 2 near the end of the "T"-shaped wire clamp 5 on the three epoxy resin spacer bars 1, the support structure is at its minimum. In this embodiment, in order to ensure the stability of the connection of the three epoxy resin spacer bars 1, it is required that each epoxy resin spacer bar 1 has at least two first adjustment holes 2 and at least two second adjustment holes 9 of its corresponding adjustment part cooperate with each other to fix the three epoxy resin spacer bars 1, such as... Figure 5 As shown.
[0024] The number of second adjustment holes 9 on each set of adjustment sections that mate with the corresponding first adjustment holes 2 on the epoxy resin spacer 1 can be the same or different, further improving the adjustability of the support mechanism. That is, three second adjustment holes 9 on two sets of adjustment sections mate with three first adjustment holes 2 on the corresponding epoxy resin spacer 1, and two second adjustment holes 9 on another set of adjustment sections mate with two first adjustment holes 2 on the corresponding epoxy resin spacer 1, as shown below. Figure 9 As shown.
[0025] In another embodiment, when the support structure is composed of three epoxy resin spacers 1, the ends of the three epoxy resin spacers 1 are fixedly connected by two first epoxy resin clips 8 of the adjusting device, so that the support structure as a whole is star-shaped. All three epoxy resin spacers 1 are located between the two first epoxy resin clips 8. To facilitate fixing the three epoxy resin spacers 1, three sets of adjusting parts are provided on the first epoxy resin clips 8. The three sets of adjusting parts are star-shaped, and each set of adjusting parts corresponds to and cooperates with the three epoxy resin spacers 1. Figure 1 As shown.
[0026] The relative positional relationship between the epoxy resin clips and the support structure can be adjusted by adjusting the number of the second adjustment holes 9 of the three sets of adjustment parts that cooperate with the first adjustment holes 2 on the three epoxy resin spacers 1, thereby further adjusting the spacing between the supported wires 7.
[0027] A reinforcing insulation component is fixedly connected to one end of the epoxy resin spacer 1 near the "T"-shaped clamp 5. The reinforcing insulation component is located between the first adjustment hole 2 and the "T"-shaped clamp 5. The reinforcing insulation component is a silicone rubber sheath 4 or a silicone rubber heat-shrinkable skirt 6. When the reinforcing insulation component is a silicone rubber heat-shrinkable skirt 6, the skirt opening of the silicone rubber heat-shrinkable skirt 6 faces the "T"-shaped clamp 5, achieving rain and snow barrier between the epoxy resin spacer 1 and the "T"-shaped clamp 5, and increasing the phase-to-phase creepage distance.
[0028] The “T” type wire clamp hardware 5 adopts the widely used bolt-type galvanized aluminum alloy T-type drain wire clamp, which is a standard prefabricated part. Different specifications can be selected for adaptation according to the wire diameter of the conductor 7, and the cost is low.
[0029] In this embodiment, epoxy resin spacer 1 is made by mixing epoxy resin E51 with polydimethylsiloxane and incorporating silica microparticles into a single casting. This process can achieve ideal strength, bonding force, and hydrophobic and antifouling capabilities, while ensuring high mechanical strength and low cost, thus balancing mechanical strength and lightweight requirements.
[0030] The working principle of this utility model: When the anti-galloping support device of this utility model needs to be applied to a 10kV power distribution line, the "T"-shaped wire clamps 5 fixedly connected to each epoxy resin spacer 1 are fixedly connected to the three-phase conductors 7 respectively. Installation can be carried out using an insulated bucket truck for live-line work, making the installation method simple. When the support structure is linear, the length of the support structure is adjusted according to the distance between the phase conductors 7, and three anti-galloping support devices are fixedly connected between each pair of phase conductors 7. When the support structure is star-shaped, the relative positional relationship between the adjusting device and the three epoxy resin spacer 1 of the support structure is adjusted according to the actual spacing of the three-phase conductors 7, and the "T"-shaped wire clamps 5 fixedly connected to the three epoxy resin spacer 1 are fixedly connected to the three-phase conductors 7 respectively. Installation can be carried out sequentially, from top to bottom.
