Description
Technical field
The utility model is related to a kind of hydraulic turbine, particularly a kind of hydraulic turbine collector ring.
Background technology
At present, in traditional hydrogenerator collector ring structure, exciting current passes through carbon brush and conducting ring, conductive lever
And excitation lead, it is that unit sets up magnetic field.This form seems complicated in structure, there is the spiral shell of support between two conducting rings
Bar, the screw rod for also having conduction；Exciting current increases by a ring intermediate links, adds stream by the conduction of copper conductive lever
Logical hidden danger, and overcurrent load capacity must be considered, otherwise there is the too high potential safety hazard of temperature；And traditional structure is in electricity
Stand in field-mounted process, site operation personnel installs cumbersome, after the excitation lead extension that one is drawn by pole coil, palpus will
The curved punching of lead, reconnects on conductive lever and is tightened by nut, the trouble in assembling, unloading process.
Utility model content
The purpose of this utility model is just to provide one kind and is convenient to mount and dismount, and can effectively prevent the collector ring of ground connection.
The purpose of this utility model realized by such technical scheme, a kind of hydraulic turbine collector ring, including rotating shaft
And support, conductive lever is vertically arranged with described support, the brush holder with carbon brush is provided with the conductive lever, in institute
State and collector machine is provided between brush holder and rotating shaft, the collector machine is connected by fixed mount with rotating shaft, the current collection
Loop device is contacted with the brush holder.
Wherein, the collector machine includes vertical and be arranged in parallel screw rod with conductive lever, is set on the screw rod
There is insulating barrier, conducting ring A and conducting ring B, the conducting ring A and conducting ring are respectively arranged with the upper and lower part of the screw rod
B is connected by excitation lead A and excitation lead B with the rotating shaft lead being arranged in rotating shaft respectively；The conducting ring A and conducting ring
B is contacted with carbon brush respectively.
Further, described fixed mount one end and the middle part of screw rod are connected, and positioned between conducting ring A and conducting ring B, it is described
The fixed mount other end is connected with rotating shaft.
For the ease of dismounting, the rotating shaft bottom is provided with platform, the outer face of the platform is provided with collets；
Insulating part is provided with the fixed mount；The excitation lead A pass through insulating part, the excitation lead A, excitation lead B and
Rotating shaft lead is connected with collets,.
By adopting the above-described technical solution, the utility model have the advantages that it is simple in construction, with low cost, using it not
But area of dissipation can be increased, potential safety hazard is reduced, but also facilitate dismounting, production cost is reduced.
Brief description of the drawings
Brief description of the drawings of the present utility model is as follows：
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings, but the utility model
These embodiments are not limited to, any improvement or replacement on the present embodiment essence spirit still falls within the utility model
Claim scope claimed.
Embodiment 1：As shown in figure 1, a kind of hydraulic turbine collector ring, including rotating shaft 1 and support 2, it is vertical on described support 2
Conductive lever 3 is provided with, the brush holder 5 with carbon brush 4 is provided with the conductive lever 3, between the brush holder 5 and rotating shaft 1
Collector machine is provided with, the collector machine is connected by fixed mount 6 with rotating shaft 1, the collector machine and the brush
Frame 5 is contacted.
Wherein, the collector machine includes vertical and be arranged in parallel screw rod 7 with conductive lever 3, is set on the screw rod 7
Insulating barrier 8 is equipped with, conducting ring A9 and conducting ring B10, the conducting ring A9 are respectively arranged with the upper and lower part of the screw rod 7
It is connected respectively by excitation lead A11 and excitation lead B12 with the rotating shaft lead 13 being arranged in rotating shaft 1 with conducting ring B10；Institute
Conducting ring A9 and conducting ring B10 is stated to contact with carbon brush 4 respectively.
Further, described one end of fixed mount 6 is connected with the middle part of screw rod 7, and positioned at conducting ring A9 and conducting ring B10 it
Between, the other end of fixed mount 6 is connected with rotating shaft 1.
For the ease of dismounting, the bottom of rotating shaft 1 is provided with platform 14, is provided with absolutely in the outer face of the platform 14
Edge block 15；Insulating part 16 is provided with the fixed mount 6；The excitation lead A11 passes through insulating part 16, the excitation lead
A11, excitation lead B12 and rotating shaft lead 13 are connected with collets 15.
In the utility model, excitation lead A11 and excitation lead B12 are connected to conducting ring A9 and conducting ring B10
On, which not only adds both positive and negative polarity conducting ring spacing, while increasing distance to the ground, the probability of appearance over the ground is dropped significantly
It is low so that the width and conducting ring cross sectional shape of conducting ring change, and add area of dissipation, lead directly connects with conducting ring
Connect, it is ensured that pick-up current density is smaller；Platform 14 and collets 15 are set to be used for excitation lead A11, excitation lead B12 and turn
The fixation of axle lead 13 so that lead is operationally safer, while also allowing for assembly and disassembly.
