Description
Technical field
The utility model relates to wind-driven generator, is specifically related to a kind of Ultra-Low Speed of obtaining by electronic circuit control, the novel permanent magnetic wind-driven generator of super wide working speed scope.
Background technology
In existing technology, can effectively generate electricity under low speed in order to guarantee generator, often the capacity of motor make bigger, the volume of motor also can increase simultaneously simultaneously, thereby causes a large amount of wastes of material and lower operating efficiency.In the actual motion of wind-driven generator, require generator also must have the working range of non-constant width, purpose is, in order under less wind speed, can effectively to send utilizable electric power, because the magnetic field intensity of permanent magnet generator is substantially invariable, pressure regulation is very difficult, people usually reach the working range of its broad by the mode of leakage field design for this reason, yet this mode makes the volume of generator, weight raise significantly, stock utilization is low, loss strengthens, and causes the waste of the various materials and the energy.
The utility model content
The technical problems to be solved in the utility model is, a kind of Ultra-Low Speed, wide speed range, little, in light weight, the high efficiency permanent-magnetic wind driven generator of volume are provided.
The technical scheme that the utility model provides is: by a kind of specific generator unit stator winding, adopt its winding string of electronic circuit control or mode in parallel to adjust, make its its serial or parallel connection of conversion under certain rotating speed, to reach the purpose of ultralow, super wide rotating speed output effective voltage; Because what this conversion was adopted is the mode of direct series and parallel winding, so conversion efficiency is very high, can reach permanent power transfer, thereby whole efficiency is very high.
A kind of novel permanent magnetic wind-driven generator, it is characterized in that adopting the generator unit stator winding adopt two-wire and around form carry out coiling, being cascaded by switching device end to end of two windings, control circuit B passes through D1, D2 powers to the voltage comparator circuit of being made up of operational amplifier IC1, the voltage comparator circuit that operational amplifier IC1 forms detects the voltage on winding L1 and the L2, and output signal, this signal amplifies by triode Q1, driving switch device J1, J2, by the comparison circuit of forming by IC1 output voltage is controlled, by to switching device J1, J2's is logical, disconnected, changing generator unit stator winding L 1 and L2 is serial or parallel connection.
When relay J 1, J2 were in shutoff, generator unit stator winding L 1, L2 were series connection, and at this moment generator can be under the rated speed below a times, output rated voltage; When relay J 1, J2 energising, generator unit stator winding L 1, L2 parallel connection, at this moment under normal design speed, work output rated voltage and rated power of generator.
Its operation principle is:
Generator unit stator winding L 1 in the A master section, L2, its structure adopt two-wire and around form carry out coiling, when generator operation reaches rated speed 1/2, voltage on the stator winding L1 is rated voltage 1/2, because relay contact J1-1, J2-1 are in normally off, be that voltage on L1, the L2 is in series connection, so output voltage just can reach rated voltage under 1/2 rotating speed, thereby can effectively provide sufficiently high electric power to the outside.When the generating rotating speed continues to raise, voltage on stator winding L1 and the L2 also increases, when reaching certain numerical value, as: (the purposes different parameters was different in about 75% o'clock for rated voltage, in comparison circuit, can be provided with arbitrarily), the voltage comparator circuit of being made up of operational amplifier IC1 detects data, and output signal, this signal amplifies driving relay coil J1 by triode Q1, J2, relay contact after the closure makes generator unit stator winding L 1, be in state in parallel with L2, at this moment output voltage has only L1 or one group of winding voltage of L2, like this because electric current can increase 1 times, so power output can reach rated value.When output voltage was lower than the decline test point that operational amplifier IC1 sets, as 75% o'clock of: rated voltage, relay contact J1-1, J2-1 discharged, and output voltage repeats to get back to initial series connection again, thereby forms Automatic Cycle control.
