Description
Technical field
The present invention relates to on-line monitoring field, particularly relate to a kind of temp measuring method based on infrared thermometer and system.
Background technology
The fault of power equipment has varied, but great majority are all with the phenomenon of heating.From the angle of infrared diagnostics, be usually divided into external fault and internal fault.As everyone knows, in Operation of Electric Systems, because current effect produces ohmic loss, and can there is the various web member of quantity, joint or contact in current－carrying conductor on the whole loop of electric energy conveying.In the ideal case, various web members, joint or contact resistance in transmitting loop are lower than the resistance of connected conductor part, so, the loss heating of connecting portion can not higher than the heating of adjacent current－carrying conductor, but once some web member, joint or contact are because of bad connection, cause contact resistance to increase, this position just has the temperature rise of more ohmic loss and Geng Gao, thus causes local overheating.This type of belongs to external fault usually.The feature of external fault is: local temperature rise is high, and as do not processed in time, be worse off fast, easily formation accident, causes damage.It is larger that external fault accounts for defective proportion.
The internal fault of so-called high voltage electric equipment, mainly refers to the electric loop fault and the deteriorated various faults caused of insulating medium that are enclosed in solid insulation and apparatus casing inside.Because this kind of fault appears at the inside of electrical equipment, the temperature rise of the equipment appearance therefore reflected is very little, usually only has a few K.Detect the sensitivity requirement of this fault to checkout equipment higher.The feature of internal fault is: defective proportion is little, and temperature rise is little, and harm is large, high to infrared detection equipment requirement.
Infrared ray is a kind of electromagnetic wave, has the essence the same with radiowave and visible ray.Ultrared discovery is that the mankind are to the once leap be naturally familiar with.The electronic installation utilizing certain special converts the Temperature Distribution of body surface to human eye visible image, and is referred to as infrared thermal imaging technique with the technology of different colours display object surface Temperature Distribution, and this electronic installation is called thermal infrared imager.
Infrared thermometer (also referred to as thermal infrared imager) utilizes infrared eye, the infrared energy distribution pattern that optical imagery object lens and optical mechaical scanning system (also can save optical mechaical scanning system under focal plane technology advanced at present) accept measured target is reflected on the light activated element of infrared eye, between optical system and infrared eye, an optical mechaical scanning mechanism (utilizing the focal-plane thermal image systems of focal plane technology then without this mechanism) is had to scan the infrared thermal imagery of testee, and focus in unit or spectroscopic detectors, infrared energy is converted to electric signal by detector, through amplifying process, conversion or video standard signal show Infrared Thermogram by TV screen or monitor.
This Infrared Thermogram is corresponding with the heat distribution field of body surface, is thus in fact the thermal imagery distribution plan of measured target object each several part infrared radiation.And due to infrared signal very weak, compared with visible images, level and stereoscopic sensation can be lacked, therefore, can for more effectively judging the infra-red heat distribution field of measured target in actual act process.
In power industry, very early thermal infrared imager is applied on the safety inspection of equipment, detected by its thermal defect to electrical equipment and circuit, as transformer, sleeve pipe, isolating switch, disconnecting link, mutual inductor, power capacitor, lightning arrester, power cable, bus, wire, combined electrical apparatus, insulator chain, low-voltage electrical apparatus and the secondary circuit etc. of equipment with electric current, voltage-caused heating or other thermal effects, this generation for Timeliness coverage, process, prevention major accident can be played very crucial and effectively act on.
Device temperature in current transformer station detects and measures mainly through librarian use Portable infrared imaging instrument, the equipment heat radiation detected due to Portable infrared imaging instrument is vulnerable to the interference of the factors such as temperature, humidity, wind speed, sunlight irradiation, this not only requires higher to the overall qualities of testing staff, often increase staff labour intensity and can not the defect of Timeliness coverage equipment.Also there is detection frequency in addition low, human users affects the problems such as testing result, cannot reflect the practical operation situation of equipment timely and effectively, specifically comprise:
Problem one, measure interval long, malfunction monitoring rate is low:
Current patrolling and examining adopts regular personnel's routine inspection mode mostly, and due to employing, personnel patrol and examine, and patrol and examine and there is discontinuity.Different substation to patrol and examine interval different, emphasis large-scale substation patrols and examines interval mostly monthly, and Small Substation patrol and examine half a year even annually, patrol and examine the neutral gear phase that existence is larger.Be just the period of the protection of electricity of the Olympic Games, the emphasis large-scale substation of 500KV, equipment routing inspection can only carry out several times every day, still there is undetected possibility.
Problem two, checkout equipment initialization condition are inconsistent, and data wander is large:
Because inspection device is discontinuity work, the basic status that the temperature measuring equipment for sensitivity is started shooting at every turn is all different, and equipment is shorter relative to the working time, and cannot enter long-term steady state (SS), thus system exists relatively large deviation when patrolling and examining.Repeatedly data are patrolled and examined for same equipment, owing to there is system deviation, cannot precise alignment be carried out, also make the rate of patrolling and examining of system reduce.
Problem three, fault instantaneity detect, and trendless is predicted:
Detection for equipment is the current running status of judgment device, i.e. the running status of a time point, instead of equipment continuous print state, more cannot analyze the running status trend of equipment.The temperature trend change of equipment often can reflect the time of day of equipment, and therefore patrolling and examining of instantaneity exists certain error.
Problem four, tables of data stratification, without analysing in depth:
For the fault that equipment is early stage, often the local temperature of equipment there will be toward renaturation change.If the running temperature of equipment is normal when patrolling and examining, can not investigate the fault of equipment completely, namely data are the data on top layer, and cannot carry out deep analysis and judgement, also make system rate of patrolling and examining reduce.
Problem five, alarm threshold are fuzzy, and error in judgement is large:
The temperature survey of equipment can be subject to the impact of temperature and sunlight, thus has suitable difficult point when judging alarm temperature, early stage especially in equipment failure, and patrol officer often because the judgement of mistake, loses best servicing time.
Problem six, human factor are more, and equipment Inspection error is large:
Because equipment routing inspection is mainly through personnel's routine inspection mode, be no matter the position of testing of equipment, or all there is more human factor in the setting of device parameter.For the personnel of different experience, it is also far from each other to patrol and examine effect, thus in equipment routing inspection, there is comparatively big error.
Problem seven, patrol and examine and there are differences at every turn, easily produce omission:
At every turn patrolling and examining of equipment affects comparatively large by human factor, environmental factor, apparatus factor, and there is certain otherness, the fault diagnosis for equipment easily produces omission.
Problem eight, cruising inspection system are on-the-spot formula, cannot be synchronous with command centre:
Process of at every turn patrolling and examining is all that designated person detects to scene, after patrolling and examining end, data preparation is reported command centre.Thus the data that obtain of command centre, there is larger time lag, the process of fault also exists asynchronous.
Problem nine, cruising inspection system are standalone, cannot complete data real-time interconnection:
Inspection device is unitization design, and without network savvy, the mode that data can only be reported by personnel is carried out, cannot unified management.
Problem ten, image data are few, and malfunction monitoring rate is low:
Because monitoring time is relatively short, data acquisition amount is less, thus cannot carry out multianalysis to data, and malfunction monitoring rate reduces.
