Description
Technical field
The utility model relates to the icing simulation field, especially relates to a kind of icing analogue means.
Background technology
The powerline ice-covering problem of waving is universally acknowledged technical barrier, and anti-to wave research all significant to prevent and reduce natural disasters technology and even national economy etc. of national grid safety, electrical network.The icing analogue means is that a kind of transmission line wire that is installed on is used for the state of analog conducting wire icing and then the device that research is waved.This device will successfully be simulated and waved, and except the excitation of external condition wind, one of important factor is necessarily to wave in the cycle, and simulation ice production apparatus and wind direction have certain suitable angle.
Traditional icing analogue means is formed by aluminium section bar, two kinds of materials processings of timber.
As shown in Figure 1, aluminium section bar simulation ice cross sectional shape is half elliptic, and the right part inboard is provided with convexity, is installed on the lead 2.Because transmission line wire is steel-cored aluminium strand, fixedly the time, surface of contact is little with it for aluminium section bar simulation ice, and friction force is little, is difficult to combine closely; And simulation ice is mainly used in the analog line icing and waves; Require itself and lead to remain the installation of fixed angle, aluminium section bar simulation ice can not be closely fixing with lead owing to its natural speciality; Situation with respect to the lead rotation often takes place, and its angle with wind direction is difficult to fixing more and adjusts.When therefore it is installed on transmission line of electricity, need other auxiliary anchor ear that itself and lead are tightened, this has just increased Master Cost and construction cost.In addition, aluminium section bar material and processing charges are high, and be when producing the simulation ice of same weight, more expensive more than 70% than PVC section bar simulation ice.
As shown in Figure 2, timber simulation ice production apparatus has same problem with aluminium section bar, and timber simulation ice medial surface is the semicircle coaxial with lead, and at first it can not well be fixed with lead, more can not adjust the angle of itself and wind direction easily.
The state that simulation ice why can analog conducting wire be waved, one of reason are that its density and the ice and snow density and the weight of adhering to are approaching, and when reaching suitable wind direction and forming stable updraft, lead is promptly waved.And timber simulation ice is difficult to artificial control because itself density receives the self-sown restriction of timber, more can't be with the unified density value for confirming of all devices that is installed on circuit; Add man-hour in addition; It is difficult to pour out accurately, glibly angle, radian with wire-bonds the decision of the speciality of timber itself, thereby it is when fixing with lead, the smoothness excessively inadequately of two kinds of materials; Be difficult to form stable updraft, the weak effect that simulation is waved.The 3rd, timber is the same with aluminium section bar with the combination between the lead, can not fix well, and perhaps needing fixedly the time so both increase executive cost by certain external force means, has increased difficulty of construction again.
Simulation ice can successful analog conducting wire wave depend on following some:
1, approaching with natural icing density weight, while consistent in density, adjustable; 2, with wind direction suitable angle is arranged; 3, closely fixing with lead, refer to that mainly both fix by relative position when setting angle is confirmed, can not produce rotation with respect to lead, situation such as mobile; The aerodynamic force characteristics of waving when 4, profile, density meet ice and snow attached to lead.
In addition, consider real feasibility, simulation ice material should have cheap, durable; Processing and fabricating is convenient; Be convenient to characteristics such as operation installation at the scene, construction cost is low, use is flexible.
