Description
Technical field
It the utility model is related to a kind of generator, more particularly to a kind of generator of the rotor windings temperature of measurement in real time.
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, temperature sensor is difficult to pass temperature signal
It is sent in the instrument and equipment of 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, at this moment if 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 continues to run with, to 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
The purpose of this utility model is to provide a kind of generator of the rotor windings temperature of measurement in real time.It has structure simple
The advantages of single, easy to use, cost is low.The requirement of measurement generator amature winding temperature in real time can be met.
The utility model is achieved like this, a kind of generator of the rotor windings temperature of measurement in real time, it includes generating electricity
Machine, temperature sensor, rotor windings, slip ring, carbon brush, rotating shaft, bearing cap, outlet box；It is characterized in that：Set respectively on generator
There are temperature sensor, rotor windings, slip ring, carbon brush, rotating shaft, bearing cap, outlet box, the rotating shaft rear end processing temperature sensor
Wire hole, rotating shaft afterbody is provided with the shaft extension of an installation slip ring；In the embedding TEMP in rotating shaft bottom during rotor windings coiling
Device；Slip ring is arranged on to the rear end of rotating shaft；The lead wire of temperature sensor passes through the rear wire hole of rotating shaft, the temperature sensor
Lead wire be connected on slip ring；The mounting hole of processing installation carbon brush, carbon brush is arranged on bearing cap, by carbon brush on bearing cap
Lead wire be connected in outlet box.
Temperature sensor described in the utility model 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.
It is of the present utility model to have the technical effect that：The utility model has the advantages of simple in construction, easy to use, cost is low.
The temperature of the rotor windings of rotation can be measured in real time, when generator overload, slow-speed of revolution operation, rotor interturn short-circuit
Temperature when being raised etc. rotor windings temperature caused by abnormal conditions is measured, and the instrument that temperature signal is sent to correlation is set
It is standby that rotor windings temperature is carried out to monitor in real time, alarmed, the too high abnormal conditions of generator amature winding temperature are found in time, are had
Effect ensures the safe and reliable operation of generator.
Brief description of the drawings
Fig. 1 is the front view of the utility model generator.
In figure, 1, generator 2, rotor windings 3, temperature sensor 4, rotating shaft 5, slip ring 6, carbon brush 7, bearing cap
8th, outlet box.
Embodiment
The utility model is achieved like this, a kind of generator of the rotor windings temperature of measurement in real time, it includes generating electricity
Machine 1, rotor windings 2, temperature sensor 3, rotating shaft 4, slip ring 5, carbon brush 6, bearing cap 7, casing 8；As shown in figure 1, after rotating shaft 4
The wire hole of processing temperature sensor 3 is held, in the shaft extension of the installation slip ring 5 of the afterbody of rotating shaft 4 increase by one.During 2 coiling of rotor windings
The embedding temperature sensor 3 in its bottom.Slip ring 5 is arranged on to the rear end of rotating shaft 4, then the lead wire of temperature sensor 3 is passed through and turned
The lead wire of temperature sensor 3, is then connected on slip ring 5 by the rear wire hole of axle 4.The processing installation carbon brush 6 on bearing cap 7
Mounting hole, carbon brush 6 is arranged on bearing cap 7, then the lead wire of carbon brush 6 is connected in outlet box 8.So can be from outlet box
The real time temperature signal of rotor windings 2 is obtained in 8, this signal can be connected to the instrument and equipment of correlation, generator 1 is run by user
When rotor windings 3 temperature monitor in real time, alarm, reach the protection safe operation purpose of generator 1.
