Description
Technical field
The utility model is related to a kind of motor temperature detection devices.
Background technology
The rise of temperature during motor running directly influences service life and the operational reliability of motor.It accurately estimates simultaneously
The Wen Sheng of motor is detected, can not only ensure the safe operation of motor, but also to improving the service life of motor, saving material
And electric energy and realization the Automation Design have important realistic meaning.There was only the specific pre-buried temperature of motor interior at present
Outside sensor, most of motor all rise warning function without temperature, and temperature sensor is used for the iron core temperature of measurement motor,
But electric machine iron core does not have pre-buried temperature sensor.In the prior art, the temperature of electric machine iron core is measured, it just need to be by temperature sensor
It is placed at winding, it is necessary to motor be dismantled, embedment sensor.But the difficulty for dismounting motor is larger, and can change original match somebody with somebody
Precision is closed, and the sensor being once embedded to breaks down, and maintenance is also extremely inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of motor temperature detection device, common motor can be made to possess Wen Sheng
Data provide function.Its corresponding control system is enable to read the temperature parameter of motor, and is handled it in real time, plays protection
Motor realizes the purpose of closed loop automation control.
The technical solution adopted in the utility model is：
A kind of motor temperature detection device is matched somebody with somebody including the mounting groove being arranged on motor body and with mounting groove screw thread
The bushing of conjunction and the temperature sensor for monitoring motor temperature value size, slot bottom and the motor machine of the mounting groove
The thickness of core is no more than 2cm；The probe of the temperature sensor is metal probe, and outside is provided with external screw thread；It is described
Bushing for hollow cylinder body, hollow cylinder body middle position is provided with annular extension ear, hollow with cylinder vertical direction
Internal thread corresponding with the external screw thread that temperature sensor probe is set is provided on the hollow inner wall of cylinder；And the bushing
Thermal grease layer is additionally provided between being threadedly coupled with mounting groove.
Thermal grease layer is also equipped between the annular extension ear of the bushing and installation groove face.
Processor and alarm, the input terminal of the input terminal connection temperature sensor of the processor, place are further included
Manage the input terminal of the output terminal connection alarm of device.
The utility model is by setting mounting groove on existing motor body and being passed simultaneously with mounting groove and temperature
Sensor size three agrees with the bushing being process, and temperature sensor is mounted on bush inside, is then commonly mounted on electronic
In the mounting groove of machine, motor is made to possess the function of providing temperature parameter, handled by corresponding control system and its parameter is carried out
Processing, the upper limit of design temperature.When the temperature of motor in operation is more than the upper limit of setting, control system control motor
It shuts down, plays protection motor, the purpose for realizing closed loop automation control.Further by setting processor and alarm
Device carries out Realtime Alerts to overtemperature, increases protective effect.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
As shown in Figure 1, the utility model includes a kind of motor temperature detection device, including being arranged on motor body
Mounting groove 1 and temperature sensor 3 with the bushing 2 of mounting groove thread fitting and for monitoring motor temperature value size,
The slot bottom of the mounting groove 1 is not more than 2cm with the thickness of motor movement；The probe of the temperature sensor 3 is visited for metal
Head, and outside is provided with external screw thread；The bushing 2 is hollow cylinder body, and hollow cylinder body middle position is hung down with cylinder
Nogata is provided with outer with temperature sensor probe setting to annular extension ear 6 is provided on the hollow inner wall of hollow cylinder body
The corresponding internal thread of screw thread；And the bushing be threadedly coupled with mounting groove between be additionally provided with thermal grease layer 5.
Hole for hoist may be employed in mounting groove described in the utility model.Hole for hoist is that motor designs processing when dispatching from the factory
It finishes, but existing hole for hoist hole depth is smaller, and it is distant with the movement of motor, the measurement error of generation is larger, institute
Generally still to take new processing, the thickness for making the slot bottom of hole for hoist namely mounting groove and motor movement is 2cm, theoretically away from
It is more near more accurate from motor movement, if mounting groove 1 is through hole, although error is smaller, but motor can be influenced
Performance；Temperature sensor is installed to by its external screw thread in bushing；Temperature sensor and bushing are installed to electronic by mounting groove
On machine.
The temperature sensor 3 uses finger that can experience temperature and is converted into the sensor of usable output signal.Choosing
With the PT100 of three-wire system, measurement range is 0-150 degrees Celsius.
Thermal grease layer 5 is also equipped between annular extension 1 groove face of ear 6 and mounting groove of the bushing, heat conduction can be made
Effect is more preferable, while indirectly plays the role of sealing thermal insulation.Further included processor and alarm, the processor it is defeated
Enter the input terminal of end connection temperature sensor, the input terminal of the output terminal connection alarm of processor.It is big by set temperature value
It is small, carry out moment detection temperature, and play the role of overtemperature alarm.
The utility model is installed to by bushing outside motor by setting mounting groove on motor housing, temperature sensor
On shell, the temperature of motor housing is measured, so both favourable installations, be also beneficial to the maintenance in later stage.The temperature of motor housing is general
Lower than iron core temperature 10% or so, so specific error amount is known that according to setting measurement, by measuring skin temperature
It is concluded that go out the temperature of electric machine iron core.
