Description

Technical Field

[0001] The utility model relates to the field of ice prevention in power distribution networks, and particularly relates to an on-line mechanical wave ice prevention device for distribution network lines. Background Art

[0002] The statements in this section only provide background information related to the present disclosure and may not constitute prior art.

[0003] In the power distribution network system, iced lines are a common and serious potential safety hazard. Under extreme weather conditions, a large amount of ice and snow may accumulate on the surface of the lines, resulting in increased weight, decreased electrical conductivity, and even accidents such as wire breakage and short circuit.

[0004] After the lines are iced, their load-bearing capacity will increase and the windward area will also increase. If there is a strong wind, the lines will dance, resulting in serious consequences such as wire strand breakage, wire breakage, and even tower collapse and pole breakage, threatening the stability and safety of the lines. In addition, line dancing may also cause phase-to-phase flashover, insulator ice flashover, etc., seriously affecting the safe operation of the power grid.

[0005] Moreover, the dancing of iced conductors or the shedding of ice on a certain section will cause the conductors to jump, and these two situations are likely to cause impact loads. The characteristics of impact loads are that the action time is very short, but the force generated instantaneously is very large, which will cause serious harm to the lines. In snowy and icy weather, once icing occurs, especially in mountainous area distribution network lines, the terrain in mountainous areas is complex and changeable, vehicles cannot pass, and manual material handling and de-icing are required. The de-icing is difficult and the safety risk is high. After de-icing, due to weather reasons, the lines are iced again, so de-icing needs to be carried out back and forth, causing great losses to human and material resources.

[0006] And the current de-icing methods are as follows:

[0007] 1. Manually knocking ice or using a heavy-duty drone to knock ice with an ice-knocking rod;

[0008] 2. Using blank cartridges to vibrate and de-ice;

[0009] 3. Using a DC ice melting device to melt ice;

[0010] And there are the following problems:

[0011] 1. All of them wait until the ice has formed or is relatively serious before de-icing, with difficult de-icing and high safety risks;

[0012] 2. The de-icing method of manually knocking ice has a high manual labor intensity and high danger; the drone needs to be operated by a special person and is not suitable for removing freezing rain type ice (with tight adhesion);

[0013] 3. There are still certain safety risks during the operation of blank cartridge vibration de-icing, and the impact force is difficult to accurately control, which may cause damage to the wire.

[0014] 4. The cost of the DC de-icing device is high, the technical difficulty is high, and power outage is required for de-icing. Summary of the Utility Model
