Description
Technical field
The utility model relates to a kind of engine room cover of wind turbine Special lightning-protection needle 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 going between under engine room cover and run through cover body and carry out lightning current and dredge; traditional it be applied to nacelle cover with lightning protection pin it exists certain lightning protection limitation, comprehensive cannot carry out protecting the problem of engine room cover.
Practical novel content
The practical novel technical problem to be solved is to provide the engine room cover of wind turbine Special lightning-protection needle device of the multi-faceted protection of a kind of energy.
For solving the problem, the lightning rod that the technical scheme of practical novel employing comprises framework and is arranged on framework, it is characterized in that: the flexible pull bar that described framework comprises vertical bar, big cross bar and is rotationally connected with big cross bar, lightning rod is all installed at described big cross bar two ends.
Described Special lightning-protection needle device, it is characterised in that: described lightning rod upper end is fixedly connected with the handrail being welded on big cross bar.
Described Special lightning-protection needle device, it is characterised in that: being provided with little cross bar above described lightning rod, described little cross bar two ends install anemoscope, wind indicator respectively.
Described Special lightning-protection needle device, it is characterised in that: aviation obstacle lamp is not installed in the extension at described big cross bar two ends.
Described Special lightning-protection needle device, it is characterised in that: connecting big ear stud bottom described vertical bar, described big ear stud is connected with backing plate by bolt.
Described Special lightning-protection needle device, it is characterised in that: described lightning rod is set on sleeve pipe and is fixed by stationary installation, and described sleeve pipe is fixed on big cross bar and/or handrail.
Described Special lightning-protection needle device, it is characterised in that: described stationary installation is the stainless steel pin and split pin being located on sleeve pipe.
Described Special lightning-protection needle device, it is characterised in that: it is connected grounding wire between described big ear stud and vertical bar.
Technique scheme of the present utility model has the following advantages compared to existing technology:
By dual lightning rods apparatus design, increase engine room cover lightning strike protection point, it is to increase engine room cover thunderbolt security, avoid the interference of engine room cover internal electric components and parts, also improve the stability of communication simultaneously. In addition, this arrester device installation, maintenance are also more prone to.
Accompanying drawing explanation
It is described further practicality is novel below in conjunction with Figure of description.
Fig. 1,2 is the structural representation of the utility model arrester device different angles;
Fig. 3,4 is the partial enlargement figure of Fig. 1.
Embodiment
Shown in Fig. 4, engine room cover of wind turbine Special lightning-protection needle device of the present utility model, the lightning rod 2 comprising framework 1 and being arranged on framework 1. The flexible pull bar 5 that described framework 1 comprises vertical bar 3, big cross bar 4 and is rotationally connected with big cross bar 4, lightning rod 6 is all installed at described big cross bar 4 two ends.
Optimizing such scheme further, described lightning rod 6 upper end is fixedly connected with the handrail 7 being welded on big cross bar 4, by handrail 14, lightning rod 6 is installed more firm, prevents from being blown down by strong wind. Being provided with little cross bar 8 above described lightning rod 6, described little cross bar 8 two ends install anemoscope 9, wind indicator 10 respectively. Aviation obstacle lamp 12 is installed in the extension portion 11 at described big cross bar 4 two ends respectively. The benefit of installation 2 anemoscopes 16, wind indicator 17 is simultaneously: even if one of them fault, another can continue to use, and does not affect measurement. Connecting big ear stud 13 bottom described vertical bar 3, described big ear stud 13 is connected with backing plate 14 by bolt. Replace prior welding mode install, make installation, change convenient. Described lightning rod 6 is set on sleeve pipe 15 and is fixed by stationary installation, and described sleeve pipe 15 is fixed on big cross bar 4 and handrail 7. Described stationary installation is the stainless steel pin 16 and split pin 17 that are located on sleeve pipe 15. When lightning rod 6, anemoscope 16 or wind indicator 17 are out of order, it is not necessary to whole device is pulled down, as long as taking down stationary installation, lightning rod being glided and changes relevant equipment, substantially increasing the convenience of maintenance.
