Accompanying drawing explanation
Fig. 1 is the structural representation of existing hydrogenerator center brush part.
Fig. 2 is that the structural representation moving back control device thrown by this utility model brush.
In figure: 1-collector ring, 2-conducting ring, 3-brush carrier, 4-brush, 5-brush is thrown and is moved back actuator.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is further described.
All features disclosed in this specification, or disclosed all methods or during step, except mutually exclusive
Speciality and/or step beyond, all can combine by any way, unless specifically stated otherwise, all can by other equivalence or there is class
Replaced like the alternative features of purpose, i.e. unless specifically stated otherwise, in a series of equivalences of each feature or similar characteristics
Individual embodiment.
As in figure 2 it is shown, this utility model brush throw move back control device include collector ring 1, conducting ring 2, brush carrier 3, brush 4,
Brush current and state sensor (not shown), brush are thrown and are moved back actuator 5 and brush is thrown and moved back controller and (do not show in figure
Go out).Brush 4 is located between collector ring 1 and conducting ring 2, and described collector ring 1 is rotatable parts, and described conducting ring 2 is stationary part
Part, described brush 4 and the brush carrier 3 for fixed brush 4 are conductive component.
Described brush current and state sensor are located on brush 4, the outfan of brush current and state sensor and electricity
Brush is thrown and is moved back the input of controller and be connected, and brush is thrown and moved back the outfan of controller and throw with brush and move back actuator 5 and be connected, brush throwing
Move back actuator 5 to be connected with brush 4.Described brush throw move back actuator 5 be pneumatic machinery, hydraulic machinery, cam drive machinery,
