Description
Technical field
The utility model relates to large-size machine stator winding lead-out wire interconnection technique, is related specifically to a kind of large-size machine stator winding lead-out wire collector ring structure.
Background technology
The stator winding of big current large-size machine usually adopts the meticulous coiling of electromagnetic wire and is divided into several windings, and the two ends of each winding need to collect phase line lead-out wire corresponding to connection or zero line lead-out wire.Such as, for the stator winding of the three phase electric machine of star connection, one end of its several X phase windings needs to connect X phase lead-out wire, and the other end connects zero line lead-out wire.Stator winding due to big current large-size machine way in parallel and and all more around radical, make the quantity of multiple winding exit cable more (sometimes as many as tens of cables), make it be connected with lead-out wire comparatively difficult.Meanwhile, because tens of cables need the space being fixed on motor stator side, and need to ensure not come off in motor operation course, make the connection of large-size machine stator winding termination and fixing comparatively difficulty.Prior art large-size machine stator winding outgoing line connection structure adopts the device of pressing plate one class winding cable to be tied up the inwall being fixed on space, motor stator side, grouping connection is being carried out after cable being drawn motor stator casing, not only complex structure, but also bring difficulty to grouping connection, heat radiation and maintenance.Obviously, prior art large-size machine stator winding outgoing line connection structure also exists complex structure, brings the problems such as difficulty to grouping connection, heat radiation and maintenance.
Summary of the invention
For solving the complex structure that prior art large-size machine stator winding outgoing line connection structure exists, bringing the problems such as difficulty to grouping connection and maintenance, the utility model proposes a kind of large-size machine stator winding lead-out wire collector ring structure.The utility model large-size machine stator winding lead-out wire collector ring structure is evenly provided with more than three groups or three groups set bolts on the side surface circumference of stator, often organize set bolt along stator radial distribution and be two, set bolt is provided with collector ring clamp, and three phase line collector rings are fixed on set bolt by clamp overlap; The zero line link of stator winding is provided with zero line collector ring; The copper coin ring of described collector ring to be cross section be rectangle, the outside of collector ring and inner side are respectively arranged with the orifice plate of stube cable; Described orifice plate refers to and extends collector ring radial outside or inner side and the cable connection plate being provided with link bolt hole.

Accompanying drawing 1 is the schematic diagram of the utility model large-size machine stator winding lead-out wire collector ring structure;
Accompanying drawing 2 is the close-up schematic view of accompanying drawing 1.
Below in conjunction with the drawings and specific embodiments, the utility model large-size machine stator winding lead-out wire collector ring structure is further described.
Detailed description of the invention
Accompanying drawing 1 is the schematic diagram of the utility model large-size machine stator winding lead-out wire collector ring structure, and accompanying drawing 2 is the close-up schematic view of accompanying drawing 1, and in figure, 1 is stator, and 2 is set bolt, and 3 is phase line collector ring, and 4 is clamp, and 5 is zero line collector ring.As seen from the figure, the utility model large-size machine stator winding lead-out wire collector ring structure is evenly provided with more than three groups or three groups set bolts 2 on the side surface circumference of stator, often organize set bolt 2 along stator radial distribution and be two, set bolt 2 is provided with collector ring clamp 4, three line collector rings 3 to be fixed on set bolt 2 by clamp 4 overlap; The zero line link of stator winding is provided with zero line collector ring 5; Described collector ring (3,5) for cross section be the copper coin ring of rectangle, the outside of collector ring (3,5) and inner side are respectively arranged with the orifice plate of stube cable; Described orifice plate refers to and extends collector ring radial outside or inner side and the cable connection plate being provided with link bolt hole.When specifically installing, x, y can be connected on the orifice plate inside corresponding phase line collector ring by connecting bolt with the end cable that is connected of z phase winding.According to the number of each phase winding quantity, the orifice plate quantity be arranged on inside collector ring can be selected to be more than two or two.The winding of each phase can be facilitated, the simple and direct end cable that will be connected is connected on corresponding phase line collector ring by orifice plate, and do not need long cable.Meanwhile, the zero line link cable of each winding is connected on zero line collector ring by orifice plate.Then, each phase lead cable and zero line lead cable are connected to outside collector ring on orifice plate by connecting bolt, then it is outside to be drawn out to motor stator shell.Obviously, in the inner side of collector ring or outside, orifice plate can be set, and adopt Welding Structure to be connected on collector ring by cable.
Obviously, the Advantageous Effects of the utility model large-size machine stator winding lead-out wire collector ring structure can be connected on collector ring easily by three-phase windings at motor internal, and structure is simple, is easy to install and maintenance.
