The temperature measuring device solves the problem that an existing infrared temperature measuring device for the transformer substation can not achieve remote real-time monitoring. The infrared teletransmission temperature measuring device for the transformer substation comprises thermal infrared imagers arranged at multiple positions, needing to be monitored, of the transformer substation. The thermal infrared imagers are supported on a holder and connected to a temperature measuring main control terminal through network cables. The temperature measuring main control terminal is connected to the holder and a network transmission terminal which is connected to a monitoring host through a wireless network. As high-voltage isolation is adopted, safety is high; installing is convenient and flexible, and influence of equipment structures and space is avoided; maintenance is not needed basically after installing is carried out successfully; the temperature measuring device is free from influence of environmental factors such as dust and electromagnetic fields, and can work stably for a long time; the temperature measuring device can be used for measuring the temperature of various kinds of equipment within the visible range and the range with obstacles, and can collect temperature information with high frequency, and the real-time performance of data is high.
Description
Technical field
The present invention relates to transformer station's remote image monitoring alarm equipment, be specially a kind of infrared telemetering temperature-detecting device for transformer station.
Background technology
More and more approved along with electric system temperature measurement on-line technology and pay attention to, the temperature index parameter relating to electric power safety also becomes the main contents of system telemetry.Along with the carrying out of two-channel filter banks and the popularization of Substation Automation System, unattended station gets more and more, current unattended operation transformer station generally has complex automatic system, error proof locking system of microcomputer, part transformer station also has video fire-proof and theft-proof system, and the significant points to primary equipment, as disconnecting link contact, the temperature real time on-line monitoring of busbar joint does not also realize not forming scale in other words so far completely, existing measure is generally regularly send someone scene infrared ray or laser thermodetector telemeasurement, or manual observation, paster observation etc.Therefore, really will realize the unmanned of transformer station, improve power supply reliability, this problem must solve.
Infrared measurement of temperature is as current relatively more conventional technology, and its key detects authenticity and the reliability of data result, judges accuracy and the rationality of rejected region.So, require to be engaged in the staff of this technology, factor and the Corresponding Countermeasures such as the precision that affects infrared measurement of temperature and reliability must be understood and grasped.Affect a lot of because have of infrared measurement of temperature, as atmospheric effect, testing background impact, the impact of object radiation rate, the impact of distance coefficient, the thermal-radiating impact of neighbouring device, the impact of operating wavelength area scope and the impact etc. at instantaneous field of view angle.At present, infrared detection guiding in the electric system application of domestic authority is " DL/T664 charging equipment infrared diagnosis technology application directive/guide " and " Q/GDW charged power equipment infrared detection diagnosis code ", define the basis for estimation of infrared diagnostics object, diagnostic method and equipment deficiency in directive/guide, requirement is proposed to infrared detection and diagnostic techniques management work.Portable operation detection is mostly rested on because current infrared thermal imaging detects, the heat picture stored often is rested on to the analyzing and diagnosing in background PC computer, it can only be the analysis and Control of discontinuity, can not monitor and diagnose the operations such as the nature of trouble of thermal imagery in real time to heat distribution field, this often causes and monitors delay and cause larger property loss.In addition to some special occasions as the Warm status of unattended duty substation operation equipment detects, if the infrared equipment of portable operation, often cause lifting and the diagnosis defect such as not in time of people's labour intensity.In a word, though current infrared thermography updates raising on thermal imagery treatment technology, still need artificially in addition control operation all the time, this does not alleviate convenience of work and the realtime control of people yet.
Summary of the invention
The present invention cannot realize the problem of remote real time monitoring in order to solve existing transformer station infrared temperature measurement apparatus, provide a kind of infrared telemetering temperature-detecting device for transformer station.
The present invention adopts following technical scheme to realize: for the infrared telemetering temperature-detecting device of transformer station, comprise and be located at the multiple thermal infrared imager needing monitoring position of transformer station, being specially thermal infrared imager is supported on The Cloud Terrace, thermal infrared imager is connected to thermometric main control terminal by grid line, thermometric main control terminal is connected to The Cloud Terrace simultaneously, thermometric main control terminal is connected to Internet Transmission terminal, and Internet Transmission terminal is connected to monitoring host computer by wireless network.
Thermal infrared imager realizes the collect and transmit of infrared thermal imagery to thermometric main control terminal, thermometric main control terminal can by the control to The Cloud Terrace, adjustment thermal infrared imager towards, and by controlling the Focussing of thermal infrared imager, realize the infrared thermal imagery collection of the target to different distance.Thermal infrared imager can realize adopting various ways to obtain its Warm status to multiple thermometric target under cradle head control, realization is not stopped transport, does not contact, is carried out imaging to the Warm status of power equipment at a distance, quickly and intuitively, thus passes through state and the hidden danger defect thereof of thermography intelligent diagnostics equipment.Thermometric main control terminal and monitoring host computer coordinate the process carrying out collection signal, can realize processing infrared thermal imagery thus obtain temperature data and corresponding positional information, and including the unified management of database in; Other related datas are obtained by data-interface, as: other running state data of network load, equipment etc.; Can obtain the running temperature situation of equipment on each position of electrical network very intuitively, be convenient to operational management personnel and carry out overall situation grasp, simultaneously higher to running temperature equipment carries out tracing observation.Thermometric main control terminal can also judge collecting temperature information automatically, and according to the rule that device is predetermined, point different ranks and type, carry out early warning and warning etc. in every way.Internet Transmission terminal comprises wireless routing etc., realizes wirelessly carrying out exchanges data between thermometric main control terminal and monitoring host computer.
Above-mentioned thermal infrared imager, thermometric main control terminal, monitoring host computer etc. are existing product, and its data memory transactions circuit design, control mode, image recognition processing algorithm etc. easily realize for those skilled in the art.
Beneficial effect of the present invention is as follows: the present invention utilizes thermal infrared imager and corresponding control system and data handling system, achieves continuing to monitor of transformer station's temperature.The present invention adopts high_voltage isolation, and security is high; Flexibly easy for installation, not by device structure and spacial influence; Basic Maintenance free after successful installation; Temperature measuring equipment, can long-term stable operation not by the such environmental effects such as dust, electromagnetic field; Can be widely used in the various device temperatures measured in visual range and there is barrier, and can carry out the collection of temperature information with higher frequency, real-time property is high.
