Description
Technical field
The present invention relates to a kind of machinery security fields, what be specifically related to a kind of small-sized wind power generator prevents cable twist device.
Background technique
In physical environment, because natural wind is to being change at random, in order to make full use of at any time wind energy, the fan blade of wind-driven generator regulates direction windward automatically, the winding that current most small-sized wind power generator application conductive hoop solves outgoing cable twists off problem, because natural wind causes the sharp pounding of blower fan to the sudden change with wind speed, the elastic force of spring is recovered slow and is caused brush and electric slip ring bad connection and the scaling loss of striking sparks affects the normal operation of wind-driven generator.
The slip ring assembly (slip ring is drawn wire with three-phase and is connected) that prior art adopts, brush assembly of electric (brush is connected with the three-phase lighting outlet of generator) is fixed on fuselage by screw.When wind-driven generator is looked for wind, fuselage rotates and to drive brush assembly of electric cylinder not rotate simultaneously, and the surface of contact by brush and slip ring conducts electricity, and can effectively prevent that like this wind-driven generator lighting outlet in looking for wind process from not twisted off.
But having in strong wind and wind direction and unsettled situation thereof, can cause the sharp pounding of generator, once the surface of contact bad connection of brush and slip ring, and the elastic force of spring can not be recovered in time, produce in a short period of time electric arc, the insulating material meeting scaling loss of brush and slip ring, causes generator short circuit, thereby causes wind-driven generator to lose efficacy.
