Description
Technical field
The present invention relates to the slip ring room of motor and rotor wiring box structures, the specially motor of rotor integrated junction box structure
Slip ring room.The slip ring room is suitable for doubly-fed wind turbine, it can also be used to other winding motors.
Background technique
Slip ring room and rotor junction box are the important composition components of doubly-fed wind turbine, and usual rotor junction box is mounted on
Outside slip ring room.Rotor junction box and slip ring system are that the rotor windings of doubly-fed wind turbine connect with user's frequency converter and connect
Mouthful, three-phase conducting copper, sensor, ground interface and insulation support device are installed inside rotor junction box.Rotor wiring
Not only component is numerous for box, inside connection complexity and higher cost.It also will increase slip ring room support construction load simultaneously, lead to slip ring
Building volume increases.
Summary of the invention
The slip ring room that the present invention solves motor especially doubly-fed wind turbine is equipped with rotor wiring case because of outside, thus
Big, the at high cost problem of volume provides a kind of motor sliding ring chamber of rotor integrated junction box structure.
The present invention is achieved by the following technical scheme: the motor sliding ring chamber of rotor integrated junction box structure, including cunning
Ring casing ontology, slip ring room body interior are equipped with slip ring, brush holder；One end of slip ring room ontology is connected with attachment base, attachment base
One side end face is equipped with brush holder bar support rim；Attachment base is fixed with a side end face of brush holder bar support rim and slip ring room ontology connects
It connects；Brush holder bar support rim, other end support brush holder are fixed in one end of brush holder bar；The lower side of slip ring room ontology is equipped with
For drawing the cable locking connector of rotor leading-out wire.In use, another side end face of attachment base and electric machine stand or end cap connect
It connects, and realizes the connection of slip ring room and motor.
The motor sliding ring chamber of rotor integrated junction box structure of the present invention, eliminates rotor wiring case, reduces body
Product, reduces costs；Since the setting of attachment base changes the support fixed structure of brush holder in slip ring room ontology, keep structure tighter
It gathers, further reduces volume；Meanwhile attachment base has separated being directly connected to for slip ring room ontology and motor bearing chamber, it is therefore prevented that
Waste lubricating oil in motor bearings room enters slip ring room ontology.The present invention is suitable for doubly-fed wind turbine, it can also be used to other
Winding motor.
