Description
Technical field
The present invention relates to a kind of generator, more particularly to a kind of generator of real-time measurement rotor windings temperature.
Background technology
In order to ensure the safe and reliable operation of generator in teeth in synchronous generator calculating, it will usually to the stator of generator
Winding temperature, bearing temperature are measured in real time.Because rotor windings are rotary bodies, being difficult to of temperature sensor passes temperature signal
In the instrument and equipment for being sent to correlation, ordinary circumstance is not measured rotor windings temperature in real time.When generator overload, the slow-speed of revolution
The abnormal conditions such as operation, rotor interturn short-circuit can cause rotor windings temperature to raise, when temperature increases above permission temperature
When spending, if at this moment there is no rotor windings temperature real-time measurement, by temperature signal be sent to correlation instrument and equipment to rotor around
Group temperature monitor in real time, alarmed, and generator, which is continued to run with, will cause rotor windings to burn out.It can not thus be effectively ensured
The safe and reliable operation of generator.
The content of the invention
It is an object of the invention to provide a kind of generator of real-time measurement rotor windings temperature.It has it is simple in construction,
Easy to use, low cost advantage.The requirement of measurement generator amature winding temperature in real time can be met.
The present invention is achieved like this, a kind of generator of real-time measurement rotor windings temperature, and it includes generator, temperature
Spend sensor, rotor windings, slip ring, carbon brush, rotating shaft, bearing cap, outlet box；It is characterized in that：Temperature is respectively arranged with generator
Sensor, rotor windings, slip ring, carbon brush, rotating shaft, bearing cap, outlet box are spent, the rotating shaft rear end processing temperature sensor goes out
String holes, rotating shaft afterbody is provided with the shaft extension of an installation slip ring；In the embedding temperature sensor in rotating shaft bottom during rotor windings coiling；Will
Slip ring is arranged on the rear end of rotating shaft；The lead wire of temperature sensor passes through the rear wire hole of rotating shaft, and the temperature sensor draws
Wiring is connected on slip ring；The mounting hole of carbon brush is installed in processing on bearing cap, carbon brush is arranged on bearing cap, by drawing for carbon brush
Wiring is connected in outlet box.
Temperature sensor of the present invention is PT100 or is thermistor.
Rotor windings temperature signal is sent in outlet box by the present invention in real time by slip ring, carbon brush.
The solution have the advantages that：The present invention has the advantages that simple in construction, easy to use, low cost.Can be to rotation
The temperature of rotor windings measured in real time, when the abnormal feelings such as generator overload, slow-speed of revolution operation, rotor interturn short-circuit
Temperature when rotor windings temperature caused by condition is raised is measured, and temperature signal is sent into the instrument and equipment of correlation to rotor
Winding temperature monitor in real time, alarmed, and the too high abnormal conditions of generator amature winding temperature are found in time, hair is effectively ensured
The safe and reliable operation of motor.
