Abstract
The invention discloses a method for monitoring the temperature rising of a traction motor of a train. The method comprises the following steps of: setting correspondence relations between the voltage, current and ventilation quantity of the traction motor and the temperature rising by an experiment; detecting real-time values of the voltage, current and ventilation quantity of the traction motor in operation, and thus obtaining a corresponding temperature rising real-time value of the traction motor by calculation; and comparing the temperature rising real-time value with a critical value, and if the temperature rising real-time value is equal to or greater than the critical value, giving an alarm and cutting off the traction motor. The method has the advantages that: detection hardware such as a temperature sensor is not required; a traction converter control unit monitors the temperature rising of the traction motor; the temperature rising of the traction motor can be continuously and timely detected, and a temperature protection function of the traction motor is realized; the pre-installation and post-maintenance of a temperature sensor are avoided; the method is low in cost and convenient to operate; and the application reliability of the train is greatly improved.
Description
Technical field
The present invention relates to the railway locomotive technology, relate in particular to a kind of locomotive traction motor temperature monitoring method.
Background technology
During locomotive operation, the temperature rise of traction motor is an important parameter.Normally on the traction electric machine stator winding, temperature sensor is set, the signal of these sensors is sent into control module on the locomotive, detect the temperature rise situation of stator with this.But because the structure difference of motor is not that all motors all are fit to mounting temperature sensor, and temperature sensor also can send error message owing to faults itself sometimes, thereby influences the normal operation of locomotive.
Summary of the invention
Purpose of the present invention overcomes the deficiency of above-mentioned prior art exactly, provides a kind of and need not temperature sensor, detects more accurately, can avoid false alarm or the too high locomotive traction motor temperature rise monitoring method of temperature rise.
The objective of the invention is existing like this: a kind of locomotive traction motor temperature rise monitoring method is characterized in that taking the following step:
A. set the corresponding relation of traction motor voltage, electric current and ventilation and temperature rise;
B. set traction motor temperature rise critical value;
C. detect the instantaneous value of traction motor voltage, electric current and ventilation;
D. calculate corresponding traction motor temperature rise instantaneous value;
E. temperature rise instantaneous value and critical value are compared, if instantaneous value less than critical value, then returns step C;
If F. the temperature rise instantaneous value is equal to or greater than critical value, then reports to the police and excise this traction motor.
Adopt the solution of the present invention; needn't the reload temperature sensor etc. detection hardware; temperature rise by traction convertor control module monitoring traction motor; detection traction electric machine temperature rise that not only can be in good time continuously; enforcement is to the temperature protection function of traction motor, and install and later maintenance the early stage that need not temperature sensor.Cost is low, easy to operate, the reliability of locomotive operation increases substantially.

Fig. 2 sets up the workflow block diagram representation of traction motor voltage, electric current, ventilation and temperature rise corresponding relation for the embodiment of the invention.
Fig. 3 is the FB(flow block) synoptic diagram of embodiment of the invention control program.
Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Referring to Fig. 1, the communication input and output of traction convertor are connected to 1～6 end of locomotive control surveillance TCMS.The traction electric machine control loop of traction convertor is sent to 9,10 ends of locomotive control surveillance TCMS with voltage, the current signal of traction electric machine M1, air velocity transducer with motor ventilation amount signal be sent to locomotive control surveillance TCMS 11 ends.12～16 of locomotive control surveillance TCMS terminates to display screen.
Referring to Fig. 2, in experimental procedure, frame 1.1 detects electric moter voltage.Frame 1.2 detects current of electric.Frame 1.3 detects the motor ventilation amount.The corresponding relation S of electric machine temperature rise that frame 1.4 obtains and electric moter voltage, electric current and ventilation.Frame 1.5 is stored in the specified threshold value Q of the corresponding relation S of electric machine temperature rise and electric moter voltage, electric current and ventilation and electric machine temperature rise in the middle of the CPU of locomotive control surveillance.
Referring to Fig. 3, in control program, frame 2.1 detects voltage, electric current and the ventilation of motor.Frame 2.2 calculates the actual temperature rise value R of motor according to being stored in the electric machine temperature rise among the CPU and the corresponding relation S of electric moter voltage, electric current and ventilation.Frame 2.3 reads electric machine temperature rise critical value Q.Frame 2.4 compares the size of R and Q: if R is not more than Q, then program is returned frame 2.1; If R is greater than Q, then program enters frame 2.5, sends warning and excises this motor.
It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
