Test system for service life of fuses with overheating protection and warning function
Technical field
the present invention relates to test system for service life of fuses, be specifically related to have the test system for service life of fuses of overheating protection and warning function.
Background technology
fuse is a kind of being arranged in circuit, guarantees the electric elements of circuit safety operation.Its core is melt, plays the effect of cutting off electric current when fusing.When electric current flows through melt, the melt with certain resistance value can generate heat, square being directly proportional of thermal value and electric current.When circuit breaks down or extremely cause electric current constantly to increase, the thermal value of melt increases thereupon, until fusing disconnects circuit, plays the effect of protection.
before this patent, existing the applicant formerly applies for a patent " intelligent type test system for service life of fuses " (publication number: CN 101793943A), CN 101915887A) and " man-machine interactive fuse life test and evaluating system " (publication number: CN 202057754U) " fuse life characteristic data test and evaluating system and appraisal procedure thereof " (publication number:, above-mentioned three patents have solved respectively service life experiment system, become lifetime estimation method and the several problems of man-machine interaction of speedup factor, but in actual use owing to having realized unmanned, when occurring that system exception causes overheated even fire, can't find the very first time.
Summary of the invention
the purpose of this invention is to provide a kind of test system for service life of fuses with overheating protection and warning function; this system can real-time judge test system for service life of fuses appointed area running temperature; and when finding that temperature surpasses setting value; can automatic cut-off power and send alerting signal; thereby find that in time system overheat is abnormal, avoid the generation of fire.
for achieving the above object, the present invention has adopted following technical scheme: a kind of test system for service life of fuses with overheating protection and warning function comprises
the durability test module be connected with fuse to be measured, this module can provide and accelerate the stress test environment for the fuse group that a plurality of fuses to be measured that are in series form;
with the data acquisition module that described durability test module is connected, the various data messages of can the Real-time Collection described durability test module output of this data acquisition module;
the life appraisal module be connected with described data acquisition module, this life appraisal module can receive the data of described data acquisition module block transfer and analyze and process to obtain the characteristic of fuse group main life-span point within the phase in longevity;
the human-computer interaction module be electrically connected with described durability test module, described data acquisition module, described life appraisal module respectively, this human-computer interaction module has man machine operation interface, by this man machine operation interface, realizes control and the data interaction to described durability test module, described data acquisition module and described life appraisal module;
described test system for service life of fuses also comprises
overheating protection and alarm module, the running temperature that this module can the described test system for service life of fuses of real-time judge appointed area, and can be when finding that running temperature surpasses setting value automatic cutting system power supply, and send alerting signal.
during concrete enforcement, in described overheating protection and alarm module, the setting value of temperature is 55 degree.
utilization due to technique scheme; the present invention compared with prior art has following advantages: by overheating protection and alarm module; running temperature that can real-time judge test system for service life of fuses appointed area; and can be when finding that running temperature surpasses setting value automatic cutting system power supply; and send alerting signal; make the staff can find in time that system overheat is abnormal, avoids breaking out of fire.The test system for service life of fuses of this patent, have overheating protection and warning function, also provides directly perceived, friendly, operated succinct human-computer interaction interface, can automatically complete the durability test of fuse, and can carry out life appraisal according to test figure.
The accompanying drawing explanation
accompanying drawing 1 is schematic diagram of the present invention.
Embodiment
further set forth the present invention below in conjunction with accompanying drawing.
referring to Fig. 1; a kind of test system for service life of fuses with overheating protection and warning function; comprise durability test module, data acquisition module, life appraisal module, human-computer interaction module, overheating protection and alarm module 1; wherein durability test module, data acquisition module, life appraisal module, human-computer interaction module are prior art, and open in formerly patented claim.Following simple declaration is once: the durability test module is connected with fuse to be measured, can provide and accelerate the stress test environment for the fuse group that a plurality of fuses to be measured that are in series form, the durability test module mainly comprises central control unit, sampling unit, detection and isolated location, driver element and performance element, the concrete composition of durability test module and working method be referring to Chinese patent literature " intelligent type test system for service life of fuses ", publication number: CN 101793943A.Data acquisition module is connected with the durability test module, data acquisition module can Real-time Collection durability test module the various data messages of output, the life appraisal module is connected with data acquisition module, the life appraisal module can receive the data of data acquisition module block transfer and analyze and process after obtain the characteristic of fuse group main life-span point within the phase in longevity.The specific works mode of data acquisition module, life appraisal module is referring to Chinese patent literature " fuse life characteristic data test and evaluating system and appraisal procedure thereof ", publication number: CN 101915887A.Human-computer interaction module is electrically connected with durability test module, data acquisition module, life appraisal module respectively, this human-computer interaction module has man machine operation interface, realize control and the data interaction to durability test module, data acquisition module and life appraisal module by this man machine operation interface, specifically referring to Chinese patent literature " test of man-machine interactive fuse life and evaluating system ", publication number: CN 202057754U.Overheating protection and alarm module 1 can real-time judge test system for service life of fuses appointed area running temperature; and can be when finding that running temperature surpasses setting value automatic cutting system power supply 2; and send alerting signal; make the staff can find in time that system overheat is abnormal, avoids breaking out of fire.The setting value of temperature is 55 degree for example.
the test system for service life of fuses of this patent; there is overheating protection and warning function; also provide directly perceived, had, operated succinct human-computer interaction interface; by the selected durability test parameter of the mode of man-machine interaction; durability test can be waited for artificial screening testing data of life-span after finishing; then the Start-up life evaluation module carries out life appraisal according to test figure, and can the various Test Information of real-time query.
