Wind turbines with tower-shaped center point lightning protection

Abstract

The invention discloses a wind driven generator with an iron tower shaped central point lightning arrestor and belongs to the technical field of wind power clean energy. The wind driven generator comprises a machine head and an iron tower shaped engine base, which are connected, wherein a generator winding is introduced to a control cabinet through a lead and is respectively connected to a lamp, a network camera and a wireless transponder after modulation of a power supply. The wind driven generator is characterized in that the central point lightning arrestor provided with a network camera is arranged at the top end of the machine head, so that the generator and the network camera in wind wheels are effectively protected from lightning impulse, networking can be implemented with a computer or a smart phone to automatically preform image pick-up and store or monitor the outside and the generator operating conditions at any time, so that an Internet of Things system with security monitoring is formed, a horn-shaped air inlet is arranged in the engine base and is connected to a ventilating duct and a machine head flange of an air outlet through a flange ring, the upwards rising draft force of ground heating is utilized to promote the wind wheels to rotate automatically, the natural wind source is guided to push the wind wheels to rotate from the interiors of the first wind wheel, the second wind wheel, the third wind wheel and the engine base in an omnibearing manner, so that the power generation capacity is doubled, and through the unified design type, the wind driven generator can adapt to installation in all kinds of occasions.

Description

technical field [0001] The invention relates to a wind power generator with an iron tower-shaped central point for lightning protection, and belongs to the technical field of wind power clean energy. Background technique [0002] The vertical-axis wind turbines in the prior art do not have a uniform design, so it is inevitable that the good and the bad are different, and they cannot be adapted to the large hills, beaches, grasslands, rivers and lakes, and river banks, as small as the roof, behind the house, pastures, fields, and ground. At the same time, the defect of vertical axis wind turbine is that there is no center point lightning protection device and Internet of things monitoring measures. The stator winding of wind turbine in operation is easy to be impacted by lightning, especially in the thunderstorm season in the south. The insulation resistance of the wet generator in the wind and rain is reduced. Once the lightning strikes, the insulation of the stator winding ...

[0002] The vertical-axis wind turbines in the prior art do not have a uniform design, so it is inevitable that the good and the bad are different, and they cannot be adapted to the large hills, beaches, grasslands, rivers and lakes, and river banks, as small as the roof, behind the house, pastures, fields, and ground. At the same time, the defect of vertical axis wind turbine is that there is no center point lightning protection device and Internet of things monitoring measures. The stator winding of wind turbine in operation is easy to be impacted by lightning, especially in the thunderstorm season in the south. The insulation resistance of the wet generator in the wind and rain is reduced. Once the lightning strikes, the insulation of the stator winding will break down and short circuit or the bearing arc will be stuck. The independent lightning rod must not only comply with strict safety technical specifications, but also increase the cost and waste space. Due to the distance between the independent lightning rod and the generator, it is difficult to completely solve the lightning protection effect, and there is a lack of remote safety monitoring devices.
