Description
Technical field
Electric machines test maintained equipment field is the utility model is related to, motor insulation values can be improved automatically more particularly to one kind
Heating arrangement.
Background technology
In plum rain season due to the moisture increase in air, the insulation of motor, which is easily reduced, will influence electrical security
Can, traditional method is that motor is put into baking oven continuously to dry regular hour or in a dry environment, and this method has behaviour
The shortcomings of making inconvenient overlong time, this heater are by adding low-voltage, high-current direct current to be heated up by winding to machine winding
Reach and drive the purpose that moisture allows insulation to rise, this has the features such as safe ready small volume simple to operate.
Utility model content
The utility model mainly solving the technical problems that provide a kind of heating arrangement that can improve motor insulation values automatically,
Solves the problems, such as machine winding automatic detection heating, drying.
In order to solve the above technical problems, the technical scheme that the utility model uses is to provide one kind and can improve electricity automatically
The heating arrangement of machine insulation values, including be arranged in motor：Switching Power Supply, temperature sensor, display, control circuit and field
Effect pipe；The Switching Power Supply is provided with two；Connection composition pulsewidth of two Switching Power Supplies by FET and control circuit
Modulation circuit；The pulse-width modulation circuit accesses the winding of motor；The control circuit is also connected with the temperature sensor；The temperature
Spend the real-time temperature of sensor detection machine winding；Electric signal is transferred to the display by the temperature sensor；The control
The temperature that circuit processed detects according to temperature sensor adjusts the size of input current.
Preferably, the specification of the Switching Power Supply is 12V/1000W；The winding resistance of motor is no more than 50 milliohms.
Preferably, the display is charactron.
The beneficial effects of the utility model are：A kind of heating arrangement that can improve motor insulation values automatically is provided, utilization is low
The principle heating machine winding of high current is pressed, Frequency Conversion Design adapts to the inductance value of motor automatically.It can be achieved not dismantling motor completion
Repair the insulation of motor.And motor need not be torn open, the line that need to only connect with the mains turns on the power switch, and heating-up temperature can automatically control.
Brief description of the drawings
Fig. 1 is a kind of structure connection diagram for the heating arrangement that can improve motor insulation values automatically of the utility model；

Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
Accompanying drawing 1 to 3 is referred to, the utility model embodiment includes：
It is a kind of to improve the heating arrangement of motor insulation values automatically, including be arranged in motor：Switching Power Supply 1, temperature
Sensor 4, display 6, control circuit 3 and FET 2；The Switching Power Supply 1 is provided with two；Two Switching Power Supplies 1 are passed through
The connection composition pulse-width modulation circuit of FET 2 and control circuit 3, the electric current being transported on winding 5 can reach 400A；Should
Pulse-width modulation circuit accesses the winding 5 of motor；Control circuit 3 is also connected with the temperature sensor 4；The temperature sensor 4 is examined
The real-time temperature of measured motor winding；Electric signal is transferred to the display 6 by the temperature sensor 4；The control circuit 3
The size of the temperature adjustment input current detected according to temperature sensor 4, the data obtained in real time according to temperature sensor 4 are carried out certainly
Dynamic control heating, heating frequency realize automatic frequency-conversion with motor inductances amount, so as to reach maximum operating efficiency.The switch electricity
The specification in source 1 is 12V/1000W；The resistance of winding 5 of motor is no more than 50 milliohms.The display 6 is charactron.The motor is exhausted
Edge heater heats machine winding using the principle of low-voltage, high-current, and Frequency Conversion Design adapts to the inductance value of motor automatically.It can be achieved
Motor is not dismantled to complete to repair the insulation of motor.And motor need not be torn open, the line that need to only connect with the mains turns on the power switch, heating temperature
Degree can automatically control.This programme is also suitable the fixation maintenace point of motor, by reality suitable for the after-sales service of motor producer
Using effect it is more satisfactory.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model description, or directly or indirectly it is used in other phases
The technical field of pass, similarly it is included in scope of patent protection of the present utility model.
