Description
Technical field
The utility model relates to a kind of pressure limiting device, is specifically related to a kind of circuit structure of blower fan rectification pressure limiting device.
Background technology
The output pressure limiting technology of present blower fan is generally off-load bearing power disposable integral access technology; the off-load bearing power can not be adjustable continuously; cause off-load load inactivity regulatory function, can only play basic system protection function, make complete machine reliability relatively a little less than.
The utility model content
The utility model has been designed and developed out a kind of wind power generation that maximally utilises at the deficiencies in the prior art, guarantees wind generator system fail safe and reliability simultaneously, and less, the easy to use blower fan pressure limiting circuit structure of forming of device volume.
The utility model is achieved through the following technical solutions:
A kind of pressure limiting circuit structure of wind-driven generator includes load, off-load load, thyristor three-phase half control rectifier bridge, control circuit and the output of blower fan three-phase, and described circuit structure includes thyristor three-phase half control rectifier bridge; Described blower fan three-phase output is connected to thyristor three-phase half control rectifier bridge; The off-load load is connected between the both positive and negative polarity of thyristor three-phase half control rectifier bridge direct current output; The output of described control circuit is connected with the gate pole of thyristor three-phase half control rectifier bridge.
A kind of pressure limiting circuit structure of wind-driven generator, described load are connected with the output of blower fan three-phase or link to each other with the direct current output of thyristor three-phase half control rectifier bridge.
The utility model adopts thyristor three-phase half control rectifier bridge, thereby the access of angle of flow decision off-load load that can be by the control thyristor whether with the size of load access power, than adopting switching device to insert the mode of off-load load, has the reliability height, long service life, can regulate the power of off-load load according to the blower fan actual output voltage continuously, thereby have the advantage of high reliability and flexibility.When blower fan output voltage or power are excessive, control circuit output triggers the control signal of thyristor, thyristor three-phase half control rectifier bridge is converted to the three-phase alternating current of blower fan output direct current and inserts the off-load load, this signal also can be by the angle of flow of control thyristor, thereby adjust the power of off-load load continuously, consume unnecessary energy.When improving system effectiveness, reducing cost, maximally utilise wind energy and generate electricity by way of merging two or more grid systems, guarantee the safety and the reliability of wind generator system simultaneously.
Description of drawings
Accompanying drawing is an electrical block diagram.
Embodiment
Shown in accompanying drawing.
The utility model includes load 1, thyristor three-phase half control rectifier bridge 4, off-load load 2 and control circuit 3 and blower fan three-phase output 5; Blower fan three-phase output 5 is connected to thyristor three-phase half control rectifier bridge 4; Off-load load 2 is connected between the both positive and negative polarity of thyristor three-phase half control rectifier bridge 4 direct currents output.The output of control circuit 3 is connected to the gate pole of thyristor three-phase half control rectifier bridge 4.
The rectifier DC outlet side connects off-load load 2.Control circuit 3 detects the input voltage and the power of rectifier, by the thyristor three-phase half control rectifier bridge in the adjustable gate pole control signal of the output duty cycle control the rectifier 4 whether conducting and the angle of flow, thereby in wind-force the is excessive adjustable off-load load 2 of continuous access power when causing the blower fan output voltage too high.
The utility model allows load 1 to link to each other with blower fan three-phase output 5 as required, or promptly in parallel with off-load load 2 with the output of thyristor three-phase half control rectifier bridge 4, the flexibility that has improved system.
