The infrared energy radiating from the article to be measured is gathered by the lens (2) to be focalized on the photoelectric detector (3), and the infrared energy is converted into a corresponding electrical signal and then is transformed to be converted into a linear temperature signal value of the object to be measured after passing through the amplifier (4), the A/D converter (5), the microprocessor (6) and a processing circuit of the D/A converter (8), and finally the temperature signal value is displayed through the display screen (9). The utility model realizes the high-voltage isolation of an electronic measuring instrument and resists the interference coming from high electric fields, high magnetic fields and high electromagnetism. The utility model has the advantages of simple structure and stable work performance.
Description
Technical field
The utility model relates to a kind of temperature measuring equipment, specifically, is the online infrared temperature measurement apparatus of a kind of high-voltage board.
Background technology
At present, mainly be that the artificial thermal imaging system that regularly adopts carries out the detection of noncontact heat to high-tension switch cabinet, this detection is discontinuous measurement, can not realize real-time measurement, can not in time pinpoint the problems, cause the contact to blow easily, simultaneously, these trouble spots are charged at ordinary times, have also be in more hidden position, but after having a power failure, because there is not load, the trouble spot is difficult to determine, moreover, very big to artificial dependence, and in time do not find just may cause a serious accident.Common temperature monitoring method mainly adopts thermopair, thermal resistance, semi-conductor photodetector equitemperature sensing element to realize, these photoelectric detectors all need the plain conductor transmission signals, owing to can't guarantee to have stable insulating property, has exposed high pressure in the high-tension switch cabinet in addition, and the space is narrow and small, and common thermometry can not be used.Thereby can't realize the temperature measurement on-line of the contact in the high-tension switch cabinet, just can not in time stop fire or large-area power outage in the high-voltage board.
The utility model content
The purpose of this utility model provides the online infrared temperature measurement apparatus of high-voltage board of a kind of simple in structure, stable work in work, safety.
The purpose of this utility model realizes by following technical proposals: the utility model is by lens 2, photoelectric detector 3, amplifier 4 and A/D converter 5, microprocessor 6, telecommunication circuit 7, D/A converter 8, display screen 9 is formed, lens 2 are installed in the high-voltage board near the measured object, the far infrared wave that the target object 1 that photoelectric detector 3 is pooled to lens 2 radiates converts electric signal to, again electric signal is input to amplifier 4 input ends, after amplifying, amplifier 4 outputs to A/D converter 5, delivering to microprocessor 6 after analog to digital conversion handles, handle the back signal and output to D/A converter 8, after digital-to-analog conversion, deliver to display 9 and show by microprocessor 6.Simultaneously, the temperature signal of microprocessor is passed to panalarm and host computer by telecommunication circuit 7.
Because adopt technique scheme, the beneficial effects of the utility model are:
1) adopt Infrared to carry out signal and transmit, it has thorough, simple in structure, the characteristics such as antijamming capability strong, reliable operation of isolating;
2) overcome high-tension switch cabinet contact winding displacement forceful electric power and pressed high-intensity magnetic field, the technical barrier that temperature-sensing element can't be installed.
3) have overtemperature early warning, warning function, alarming value can be according to the customer requirements setting, report to the police output may command miscellaneous equipment or alarm sound;
4) can join standard RS-485 communication interface according to customer requirements, can network, realize concentrating temperature monitoring with host computer.
The real-time temperature rise that the utility model can be finished the switch cubicle on-line continuous detects, reach the temperature continuous monitoring, temperature-measuring range is at 0 ℃～300 ℃, by trend analysis, find secret in advance, provide warning, can note abnormalities early, take measures necessary in advance, electric fault is nipped in the bud, improved the operational safety performance of high-tension switch cabinet greatly.Can be widely used in electric power, telecommunications, metallurgy, chemical industry, finance, traffic, government bodies and enterprises and institutions etc.
Below in conjunction with specific embodiments and the drawings the utility model is further described.
