Abstract
The utility model discloses a special lightning protection arrester of wind generating set cabin cover. The technical scheme that adopts includes and forms according to the structural welding of " T " style of calligraphy through three root circle steel columns that its bottom is equipped with the mounting panel, and every root circle steel column front end is equipped with sharp portion. The utility model discloses an above -mentioned technical scheme compares prior art and has following advantage: utilize special design's wind generating set cabin cover lightning protection arrester, can install on wind generating set cabin cover surface for all -round protection wind generating set's effect. Its simple structure, simple to operate is convenient for realize, and can connect the lightning that the sudden strain of a muscle is left and right, go up three direction, has improved unit safety nature, and the cost is lower.
Description
Technical field
The utility model relates to a kind of lightning protection for engine room cover of wind turbine and connects sudden strain of a muscle device.
Background technology
Wind energy is the renewable clear energy sources that current techniques is the most ripe, possess scale development condition most. Wind power generation is that harmony between man and nature development provides basis. It is work under physical environment due to wind power generating set, inevitably it is subject to the impact of natural disaster. Due to the fast development of modern science and technology, the single-machine capacity of wind power generating set is increasing, in order to absorb more multi-energy, tower height and impeller diameter are along with increasing, relative too increases the risk being struck by lightning, and has been struck by lightning into wind power generating set safe operation endangers in nature maximum a kind of disaster. The huge energy of thunder and lightning release can cause that wind generator set blade damages, generator insulating punctures, balancing boom device burns.
China's Coastal Areas is with a varied topography, and thunder storm day is more, answers grave danger that pay abundant attention is struck by lightning and brings to wind-force Wind turbines and operation personnel. In order to reduce the loss that natural disaster is brought, it is necessary to fully understand it, and make the precautionary measures targetedly. The lightning protection of blower fan is a comprehensive lightening protection engineering, whether putting in place of lightning Protection Design, be directly connected to blower fan when thunderstorm weather can normal operation, and guarantee that the various equipment in blower fan are undermined etc.
Problem is also had to be the ground connection of the wind-force machine being arranged on hills and ridge. The soil conductivity performance in these areas is relatively poor. Usually, the engine room cover matrix material of modern large scale wind power machine is made, such as, with Fibreglass Reinforced Plastics or Timber veneer. When thunderbolt does not add the blade of protection with this kind of material manufacture, owing to these materials can not conduct lightning current, always occur damaging. Therefore, this kind of lightning protection is required it is important. Engine room cover of wind turbine Fibreglass Reinforced Plastics is made, and they should direct lightning protection aerogenerator be the most extensive topmost equipment of current Wind Power Utilization.
And engine room cover of wind turbine lightning-protection system design quality is directly connected to engine room cover internal electric loop; engine room cover is equivalent to the protective shell of wind power system, and therefore whether reasonable in design the lightning-protection system of engine room cover is is directly connected to the working order of aerogenerator and the safety of equipment. It is bear direct attack thunder due to engine room cover, cannot verify by experiment, it is necessary to lightning current size, direction should be considered at the beginning of design. Therefore the reasonableness of engine room cover lightning-protection system design just seems particularly important. The design of traditional engine room cover lightning-protection system installs lightning rod by engine room cover top, and in conjunction with go between under engine room cover and run through cover body and carry out lightning current and dredge, there is certain lightning protection limitation in it, comprehensive cannot carry out the problem of protection engine room cover.
Practical novel content
The practical novel technical problem to be solved is to provide a kind of engine room cover of wind turbine Special lightning protection and connects sudden strain of a muscle device.
For solving the problem, the technical scheme of practical novel employing comprises welds formation by three round steel posts by " T " font structure, is provided with mounting plate bottom it, and every root round steel post front end is provided with tip.
Described Special lightning protection connects sudden strain of a muscle device, it is characterised in that: the length L of described round steel post is 500mm, and diameter of phi is 12mm.
Described Special lightning protection connects sudden strain of a muscle device, it is characterised in that: described mounting plate is provided with four and installs screw.
Technique scheme of the present utility model has the following advantages compared to existing technology:
The engine room cover of wind turbine lightning protection of specialized designs is utilized to connect sudden strain of a muscle device, it is possible to be arranged on engine room cover of wind turbine surface, for the effect of omnibearing protection wind power generating set. Its structure is simple, easy for installation, be convenient to realize, and can connect the lightning dodging three directions left and right, upper, it is to increase unit safety, and cost is lower.
Accompanying drawing explanation
It is described further practicality is novel below in conjunction with Figure of description.
Fig. 1,2 is that the utility model lightning protection connects the structural representation dodging device different angles.
Embodiment
Shown in Fig. 2, engine room cover of wind turbine Special lightning protection of the present utility model connects sudden strain of a muscle device, and described lightning protection is connect sudden strain of a muscle device and formed by the welding of " T " font structure by three round steel posts 1, is provided with mounting plate 2 bottom it, and every root round steel post 1 front end is provided with tip 3.
Optimizing such scheme further, the length L of described round steel post 1 is 500mm, and diameter of phi is 12mm. Described mounting plate 2 is provided with four and installs screw.
Described in upper, not do any restriction in form to practicality is novel, disclose as above with better case study on implementation although practical novel, but and be not used to limit practical novel, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when the structure and technology contents that can utilize above-mentioned announcement make a little equivalent case study on implementation changing or being modified to equivalent variations, but every content not departing from technical solutions of the utility model, the any simple modification above case study on implementation done according to technical spirit of the present utility model, equivalent variations and modification, all still within the scope of true new technique scheme.
