Description
Technical field
The invention belongs to the thunderstorm electricity protective device field, be specifically related to a kind of lightning protection device of protecting the microgrid small-sized fan.
Background technique
Because being incorporated into the power networks, uses seldom small-sized fan; Also there is not at present ripe lightning protection scheme, in most cases, small-sized fan thunder protection in the air facility; Just lightning-protection module is set in electric loop, prevents that thunder and lightning from damaging electrical distribution system and can not protect the outdoor wind-force generator.Microgrid small-sized fan system often needs small-sized fan to be arranged in roof, and usual way is on the roof or lightning conductor is set up in higher position.The roof is established the lightning conductor lightning protection effect and is had wretched insufficiency: 1, not attractive in appearance, and often cause architectural design to be difficult to through local planning requirement.2, the lightning conductor that increases has increased building height, attracts thunderbolt all the better easily.3, lightning conductor since with the low-voltage equipment close together, low-voltage equipment generation lightning surge accident probability improves, and has bigger potential safety hazard.
Summary of the invention
It is good or do not have directly to the present situation of small-sized fan lightning protection a kind of lightning protection device of protecting the microgrid small-sized fan to be provided to the objective of the invention is to overcome present small-sized fan lightning protection effect.
The present invention realizes through following technological scheme:
A kind of lightning protection device of protecting the microgrid small-sized fan; By cage type steel cage, steel base support, fixing upper end arbor bearing, fixedly lower end arbor bearing, building lightning protection ground connection band iron, fan blade, blower fan axle, generator, the blower fan axle upper end insulation collar, the blower fan axle lower end collar that insulate constitutes; The lower end of cage type steel cage is coaxial to be packed on the steel base support, and four jiaos of this steel base support are packed on the building lightning protection ground connection band iron; The coaxial installation blower fan axle at the axis position of cage type steel cage; The upper end of this blower fan axle adopts blower fan axle upper end to insulate through fixing upper end arbor bearing, and the collar is coaxial to be installed on the cage type steel cage; The lower end of this blower fan axle adopts the insulation collar in blower fan axle lower end to be installed on the cage type steel cage through fixing lower end arbor bearing; On the blower fan axle between two arbor bearings, install fan blade, said generator is packed in the steel base support and its output shaft is connected with the blower fan axle is coaxial.
And the height of said cage type steel cage is a little more than blower fan arbor height.
Advantage of the present invention and good effect are:
It is good or do not have directly the present situation of small-sized fan lightning protection has been solved the lightning protection problem that places the small-sized fan of roof or eminence in the microgrid system that the present invention has overcome present small-sized fan lightning protection effect, can effectively protect generator to avoid the thunder and lightning infringement.Adopt apparatus of the present invention not need to build the roof lightning conductor again, avoided the negative influence on the designed appearances that blower fan brings complex building.Practical, have important popularization demonstration meaning.
