Description
Technical field
The present invention relates to a kind of yaw system of wind turbine generator, be specifically related to the main power slip ring of a kind of wind-powered electricity generation.
Background technology
The wind of occurring in nature is a kind of resource of instability, and its speed and wind direction are indefinite.In order to make wind-driven generator absorb the power of wind energy maximum, play maximum efficiency, cabin must accurately to wind, therefore must make impeller normal direction and wind direction basically identical.When change of the wind exceedes permissible error scope, component computer sends instruction of automatically going off course, and what transducer and yaw motor formed performs corrective action to wind system, makes cabin accurately to wind.The problem caused by driftage is that wind-powered electricity generation cable can reverse along with the rotation of wind power generator cabin, if wind power generator cabin repeatedly rotates to same direction, may cause wind-powered electricity generation cable winding, and hang even to twist and break.Existing technical solution is untied the mooring rope by the system of untying the mooring rope, and different wind-driven generator needs winding number of turns when untying the mooring rope to have relevant regulations.When reach blower fan regulation untie the mooring rope the number of turns time, system automatic cable-releasing, now start yaw motor rotate round about be wound around the number of turns untie the mooring rope, by cabin loop back cable without winding position.Wind-driven generator also specify the extreme value number of turns, and when fan trouble automatic cable-releasing function does not work, if when the torsion of wind-powered electricity generation cable reaches the extreme value number of turns, turn round cable switch activated, report and turn round cable fault, shutdown is waited for and manually being untied the mooring rope by wind-driven generator.In automatic cable-releasing process, automatic yaw maneuver must be shielded, namely untie the mooring rope and go off course and can not carry out simultaneously.
System of untying the mooring rope is made up of position transducer, controller, the motor etc. that unties the mooring rope, and uses this system protection cable to have following shortcoming: (1) adds system complexity and technical difficulty, makes the failure situations of whole wind generator system more complicated various; (2) in the process of untying the mooring rope, yaw system stops controlling the accurate to wind work of generator bay, it reduces the wind energy absorbed power of wind-driven generator, have impact on electricity generation efficiency; (3) when meeting with the extreme weather conditions such as typhoon, if by chance need to untie the mooring rope, because yaw system is delayed, generator bay can not make correct response to wind in time, adds the damage probability of Wind turbines under extreme weather conditions.
For overcoming prior art defect; the present invention proposes the main power slip ring system of a kind of wind-powered electricity generation; system configuration is simple; can ensure that wind turbine generator carries out electrical communications with main power rating; system of untying the mooring rope is replaced to protect cable; while minimizing failure rate, improve Wind turbines electricity generation efficiency, and reduce the damage rate of blower fan under extreme weather conditions.
Summary of the invention
The present invention is intended to prevent the distortion of Wind turbines main power cable generation wide-angle, makes system no longer need the system of untying the mooring rope, and reaches the effect simplifying Wind turbines yaw control system.
For realizing above-mentioned functions, the present invention adopts following technical scheme:
Wind-powered electricity generation of the present invention main power slip ring is the main power slip ring of following a kind of wind-powered electricity generation, is made up of multiple parts: interior chassis, outer chassis, bearing, interior insulation board, external insulation plate, copper ring, elastic connection contact, binding post.Described interior chassis and outer chassis are concentric discs, and be installed in bottom the main power slip ring of wind-powered electricity generation, the two is connected by bearing.Described interior insulation board and external insulation plate all have multiple, are strip structure, are parallel to the axis of the main power slip ring of wind-powered electricity generation, are arranged on interior chassis bottom interior insulation board, and be distributed in circumferentially, be installed on outer chassis, and be distributed in circumferentially bottom external insulation plate.Described copper ring comprises many groups, and suit is fixed on interior insulation board successively, and mounting plane, perpendicular to the axis of the main power slip ring of wind-powered electricity generation, insulate between each copper ring group and keeps a safe distance, and copper ring electric conductivity meets Wind turbines main power transmission of electricity requirement.Described elastic connection contact is divided into many groups, often group comprises multipair elastic connection contact, and often pair of symmetry is arranged on external insulation plate, often organize elastic connection contact and correspond to one group of copper ring, and the mounting plane of mounting plane and copper ring is coplanar, elastic connection contact is pressed on to ensure current lead-through on copper ring by spring all the time, and elastic connection contact electrical parameter and the main power of Wind turbines rated value of transmitting electricity mates.Binding post is installed on inside copper ring, as the electrical connection of slip ring inside cable and copper ring.The main power slip ring of described wind-powered electricity generation can be divided into inner ring and outer shroud two parts, copper ring, interior insulation board and interior chassis are connected composition inner ring, elastic connection contact, external insulation plate and outer chassis be connected composition outer shroud and outer shroud fix, by the connection of interior chassis, outer chassis and bearing, inner ring can be rotated relative to outer shroud, realize slip ring function, prevent the distortion of wind-powered electricity generation cable generation wide-angle, Wind turbines yaw system is made no longer to need the system of untying the mooring rope, be pressed on copper ring by elastic connection contact, realize the electrical communications of inner ring and outer shroud.
Compared with prior art, tool of the present invention has the following advantages:
1, the present invention is while ensure that wind turbine generator carries out electrical communications with main power rating, eliminate complicated mechanism of untying the mooring rope, simplify Wind turbines yaw system, reduce technical difficulty and manufacture, maintenance cost, the failure rate of Wind turbines can be reduced;
2, owing to saving the system of untying the mooring rope, would not occur that in the process of untying the mooring rope, yaw system stops the phenomenon accurately to wind again, improve the power that wind-driven generator absorbs wind energy, electricity generation efficiency is effectively increased;
3, when meeting with the extreme weather conditions such as typhoon, yaw system is no longer subject to the interference of the system of untying the mooring rope and delays, and can make correct response immediately, generator bay is adjusted to safest position, the probability of Wind turbines damage during reduction extreme weather conditions greatly.
