Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of transmission line, specifically, relate to a kind of ice shedding jump inhibiting device. BACKGROUND

[0002] Transmission line icing is a common meteorological phenomenon, usually occurs in low temperature, humidity greater environment, moisture or rainfall and snow on the conductor freeze to form frost. When the ice thickness is thin, its weight and the influence on the performance of conductor can be accepted by natural conditions or the bearing capacity of conductor itself, without special ice melting or deicing measures. However, when the transmission line encounters serious icing condition, the weight of ice layer increases significantly, which threatens the mechanical properties of conductor. At this time, through-flow short-circuit ice melting becomes a common solution, that is, by passing a large current to the line, the heat effect of current is used to melt the ice layer. During temperature rise or ice melting process, the ice layer may loosen and fall off due to gravity, which leads to sudden change of load on the conductor, and further causes the up-down vibration and lateral swing of the conductor, i.e. the so-called "ice shedding jump" phenomenon. Ice shedding jump not only increases the dynamic load of conductor, but also reduces the distance between the conductors of each phase and the distance between the conductor and ground line to below the safe insulation requirement, thereby causing inter-phase flashover, trip, conductor burn and other electrical accidents, as well as tower damage, wire breakage, fitting failure and other mechanical accidents, which seriously threatens the stability and safety of transmission line. To cope with the challenge of ice shedding jump, current technical field has explored various solutions, such as patent CN201920158154.1 discloses a transmission ice shedding jump inhibiting device, which includes a wire clamp, a fixed base, a safety spring and a safety connecting rod. The wire clamp is arranged at the top of the fixed base for fixing the transmission line. A cantilever beam is fixed to the upper part of the first side surface of the fixed base. A connecting spring is connected to the upper end of the cantilever beam and the lower end of the sliding counterweight. A groove is provided at the lower part of the first side surface of the fixed base. The sliding counterweight can slide up and down along the groove under the driving of the connecting spring. Through the combination of the wire clamp, the fixed base, the safety spring and the safety connecting rod, the sliding counterweight slides along the groove when the conductor vibrates, actively consumes vibration energy, so as to quickly stop the vibration of the conductor. However, this method cannot inhibit the jump when the ice layer starts to fall off. For example, patent CN111668794A discloses a spacer rod and transmission system suitable for ice shedding jump prevention and control of transmission line, which includes a core rod and a plurality of wire clamps connected to the front end of the core rod. When the line ice shedding causes ice shedding jump, the spacer rod is installed between the conductors to maintain a safe distance and prevent flashover relative to the ground line caused by conductor jump.

[0003] In the field of power transmission, galloping and ice shedding of overhead transmission lines are two major challenges commonly faced, especially in adverse weather conditions such as snowy and rainy weather in winter or high humidity and low temperature environments. These phenomena not only affect the normal operation of the line, but also can cause serious safety problems, leading to power outages, equipment damage, and other consequences. Galloping, as a complex dynamic phenomenon, is caused by multiple factors, including weather conditions, topography, wind excitation, and the structural characteristics of the line itself. Specifically, wind is the key driving force for galloping, and different wind speeds and directions have a significant impact on the shape and dynamic characteristics of the iced line, thereby changing the vibration mode of the line. When the wind excitation forms a specific angle with the line, increasing the lift in the vertical direction, the energy accumulates to the critical point, and the line will produce the galloping phenomenon. Ice, as another important trigger factor for galloping, significantly changes the shape and stress distribution of the line when the surface of the line is covered with ice, especially when the ice layer grows on one side under the action of wind, which aggravates the vibration tendency of the line and provides the necessary conditions for galloping. However, ice shedding and galloping have significant differences in causes and manifestations. Ice shedding occurs during the ice melting process, and the ice layer falls off the conductor, causing a sharp change in the load of the conductor, thereby causing the conductor to vibrate and displace violently. This jumping phenomenon increases the risk of flashover between conductors and between the conductor and the ground, leading to electrical and mechanical accidents, seriously threatening the safe and stable operation of the transmission line.

[0004] In the prior art, inter-phase spacers are widely used to suppress line galloping by maintaining a stable distance between conductors to reduce the resonance effect caused by wind. However, for ice shedding, the suppression effect of inter-phase spacers is limited because their original design is not directly to control the jumping displacement of the conductor during ice shedding, but rather to maintain a static safe distance between conductors to prevent short circuit risk during galloping. In addition, some mechanical ice shedding suppression devices reduce the jumping amplitude through resonance principles, but these devices often have poor effects due to the complexity of working conditions, weight, structural complexity, and high installation and maintenance costs. In summary, current ice shedding suppression schemes such as setting inter-phase spacers or mechanical suppression devices can alleviate ice shedding to some extent, but it is difficult to suppress jumping when the ice layer begins to shed.

DETAILED DESCRIPTION

[0026] It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict. The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0027] Combined with the drawings shown, Figures 1 to 6 The utility model provides an ice shedding jump inhibiting device, the ice shedding jump inhibiting device includes: ice separating main body 10 is constructed as can be clamped and fixed on conductor wire 20, along the length direction of conductor wire 20, ice separating main body 10 can cut off the ice on conductor wire 20.

[0028] In the embodiment, the ice-separating body 10 is clamped and fixed on the conductor 20, the ice can be segmented and isolated, and the formation of a continuous large ice layer is avoided. The ice on the conductor 20 is segmented by the isolation of the ice-separating body 10. Through the above arrangement, when the ice layer begins to fall off, the instantaneous load change caused by the simultaneous falling off of a large ice layer on the conductor 20 is reduced, so as to inhibit the ice-shedding jump of the conductor 20. Compared with the traditional inter-phase spacer and the mechanical anti-ice-shedding jump device, the ice-shedding jump resistance of the line can be obviously improved. When the ice layer is thick, especially when a large ice layer falls off, the distance between the conductors 20 may be shortened due to the jump, thereby causing inter-phase flashover or flashover between the conductor 20 and the ground wire, which are serious faults in the power system. The ice-separating body 10 prevents the continuous coverage and large falling off of the ice layer, thereby maintaining the safe electrical distance between the conductors 20 and improving the electrical safety. In addition, the use of the ice-separating body 10 can reduce the occurrence of the jump of the conductor 20, thereby saving the maintenance cost of the line to a certain extent and improving the economy and operation efficiency of the line.

[0029] It should be noted that the number of the ice-separating body 10 can be set as required. When the number of the ice-separating body 10 is two or more, the spacing between the adjacent two ice-separating bodies 10 can be adjusted according to actual needs.

[0030] When the ice thickness of the line is less than 10 mm, no ice removal measure is generally taken, and the ice falls off by gravity under natural conditions. Due to the long span of the line, the stress characteristics of the line change when the long-distance ice layer falls off at the same time, and the line jumps. Therefore, when the ice thickness of the line is greater than 10 mm, the through-flow ice melting method is generally used to make the ice layer quickly fall off. Due to the long span of the line, the line may jump seriously due to ice shedding. Therefore, by installing the ice-shedding jump inhibiting device of the present application on the conductor 20, the long span can be divided into several shorter sections, so that the ice layer falls off in segments and the ice-shedding jump of the line is effectively avoided.

[0031] In one embodiment, the ice-separating body 10 is made of aluminum alloy. Since the aluminum alloy has excellent corrosion resistance, no additional corrosion protection treatment is required on the surface of the ice-separating body 10, and long-term use can be achieved. In addition, the use of aluminum alloy can effectively reduce the weight of the product, and can avoid the problem of increased line load and sag due to excessive weight.

[0032] It should be noted that the ice-separating body 10 is made by a new forging process. After the aluminum bar is heated and forged, the casting defects such as pores and sand holes caused by the casting process are eliminated. After forging, the ice-separating body 10 is subjected to heat treatment such as T6 to ensure the strength and wear resistance of the ice-separating body 10.

[0033] For reference Figures 1 to 6As shown in the drawings, in one embodiment of the utility model, the ice blocking main body 10 is a rugby ball type or a spherical type.

[0034] In this embodiment, the rugby ball type or the spherical type design can form a physical barrier on the conductor 20, prevent continuous icing, and thus segment the ice layer. This segmentation can significantly reduce the overall weight and volume of the ice layer when it falls off, and avoid the large ice layer falling off causing the conductor 20 to jump due to ice shedding. On the other hand, the ice blocking main body 10 of the rugby ball type or the spherical type has a large radius of curvature, and the electric field strength distribution is more uniform, reducing the possibility of sharp end discharge. In particular, in high altitude or extra-high voltage transmission lines, the risk of corona discharge can be reduced.

[0035] It should be noted that the radius of curvature of the ice blocking main body 10 of the present application can be more than 160 mm, and the anti-corona effect is good. It can be used in high altitude areas above 4000 m and extra-high voltage transmission lines, and can meet the requirements of corona and radio.

[0036] In one embodiment of the utility model, the ice blocking main body 10 is made of a material with a thermal conductivity less than that of the conductor 20.

[0037] In this embodiment, when the transmission line is iced, current flow melting is a common response measure. During the ice melting process, the current passing through the conductor 20 generates heat to melt the ice layer. The thermal conductivity of the ice blocking main body 10 is lower than that of the conductor 20. In this way, the ice blocking main body 10 can act as a thermal insulation layer. On the one hand, it can reduce the loss of heat generated by the conductor 20 to the external environment, improving the ice melting efficiency. On the other hand, due to the actual application scenario, the ice blocking main body 10 may also be iced. Through the above setting, the ice layer on the ice blocking main body 10 and the ice layer on both sides of the ice blocking main body 10 can be prevented from falling off at the same time during current flow melting, so that the icing is segmented and falls off, thereby reducing the risk of ice shedding jump.

[0038] For reference Figures 1 to 6 As shown in the drawings, in one embodiment of the utility model, the ice blocking main body 10 includes a first ice blocking part 11 and a second ice blocking part 12 which are detachably connected. The first ice blocking part 11 and the second ice blocking part 12 both have a groove 13. When the first ice blocking part 11 and the second ice blocking part 12 are connected, the two grooves 13 together form a clamping channel for the conductor 20 to pass through and clamp and fix the conductor 20.

[0039] In this embodiment, the first ice separator part 11 and the second ice separator part 12 are connected and can be clamped and fixed on the wire 20. The detachable connection mode makes the ice separator body 10 more flexible during installation, which can adapt to wires 20 of different diameters and types. This design allows the ice separator body 10 to be installed without damaging the wire 20, and also facilitates replacement and maintenance, improving the adaptability and practicality of the device. The groove 13 design of the two ice separator parts can increase the contact area with the wire 20, thereby reducing the local pressure on the wire 20.

[0040] For reference Figures 1 to 6 As shown in an embodiment of the utility model, the groove 13 is an arc-shaped groove that is adapted to the wire 20.

[0041] In this embodiment, the design of the arc-shaped groove can better fit the surface of the wire 20, thereby evenly distributing the pressure of the ice separator body 10 on the wire 20 when fixing the wire 20, avoiding damage to the wire 20 such as indentation, deformation or wear caused by excessive local pressure, thereby prolonging the service life of the wire 20.

[0042] In an embodiment of the utility model, the inner wall of the groove 13 is provided with an insulating buffer pad that covers the inner wall surface of the groove 13.

[0043] In this embodiment, the insulating buffer pad can prevent direct contact between the ice separator body 10 and the wire 20 from causing wear on the wire 20, thereby prolonging the service life of the wire 20.

[0044] For reference Figures 1 to 6 As shown in an embodiment of the utility model, the first ice separator part 11 also has a first connecting hole 111, the second ice separator part 12 also has a second connecting hole 121, and the first connecting hole 111 and the second connecting hole 121 are correspondingly arranged. The ice-melting jump suppression device further comprises a connecting assembly 30, which comprises a connecting piece 31 and a locking piece 32. The connecting piece 31 is sequentially arranged through the first connecting hole 111 and the second connecting hole 121, and the locking piece 32 is sleeved on the connecting piece 31 and locks and fixes the first ice separator part 11 and the second ice separator part 12.

[0045] Through the above arrangement, the first ice separator part 11 and the second ice separator part 12 can be connected, and the ice separator body 10 can be clamped and fixed on the wire 20.

[0046] Specifically, the connecting piece 31 is a bolt, the locking piece 32 is a nut, and the first connecting hole 111 and the second connecting hole 121 are correspondingly arranged, so that the first ice partition body 11 and the second ice partition body 12 can be quickly aligned during installation, fixed through the connecting assembly 30, and conveniently and efficiently operated. Similarly, this design also facilitates disassembly and replacement during maintenance, and reduces the difficulty and risk of high-altitude operation. The use of the connecting piece 31 and the locking piece 32, especially the fixing effect of the locking piece 32, can improve the connection strength between the parts of the ice partition body 10, ensure that it will not loosen due to vibration or external impact during operation, and can be installed without borrowing large construction tools, which is portable and greatly improves the construction and installation efficiency.

[0047] For reference Figures 1 to 6 As shown in the embodiment of the utility model, the two nuts are sequentially sleeved on the bolt along the length direction of the bolt, which can improve the stability of the connection between the ice partition body 10 and the wire 20 and improve the anti-loosening effect.

[0049] In the embodiment, the installation gap provides an operation space for the installation of the connecting assembly 30, so that the operator can more conveniently align and connect the bolt and the nut when installing the ice partition body 10. The bottom surfaces of the first installation gap 112 and the second installation gap 122 are both flat surfaces, the first connecting hole 111 is arranged on the bottom surface of the first installation gap 112, and the second connecting hole 121 is arranged on the bottom surface of the second installation gap 122, which can ensure that the connection points of the first ice partition body 11 and the second ice partition body 12 are in a relatively stable position, thereby enhancing the structural stability of the ice partition body 10. In addition, the first installation gap 112 and the second installation gap 122 are equivalent to removing part of the arc surface with a small curvature radius, which can improve the field strength and prevent corona discharge, thereby enhancing the anti-corona performance of the ice partition body 10.

[0050] For reference Figures 1 to 6As shown in the drawings, in one embodiment of the utility model, along the length direction of the conductor 20, the first ice separator 11 and the second ice separator 12 both have oppositely arranged first ends and second ends, the first end of the first ice separator 11 and the second end of the first ice separator 11 are both provided with at least one first connecting hole 111, the first end of the second ice separator 12 and the second end of the second ice separator 12 are both provided with at least one second connecting hole 121, and the first connecting hole 111 and the second connecting hole 121 at the same end are one-to-one correspondingly arranged.

[0051] Through the above arrangement, more uniform stress distribution between the ice separator parts can be realized, local stress concentration caused by single-point connection can be avoided, the structural strength and stability of the ice separator main body 10 are enhanced, and the ice separator main body 10 can also maintain close adhesion and stable position with the conductor 20 even under extreme environmental conditions (such as strong wind, impact when ice falls off, etc.).
