Description
Technical field
The utility model relates to a kind of wireless temperature-measuring sensor, especially relates to a kind of U-shaped blade inserting transformer station wireless temperature measurement sensing device.
Background technology
Intelligent grid construction is that China disposes in the grand strategy of energy field, most possibly realizes the field that commanding elevation, the world is broken through, occupied to former plane.Intelligent grid construction will progressively promote the change of China's electric power basis production model, be positioned to utilize advanced communication, information and control technology, building and turn to leading in the world, the autonomous innovation of feature, the intelligent grid of distinct Chinese characteristics with informationization, robotization, interaction, is the developing direction of power industry.
The realization of intelligent grid, the on-line monitoring and the real-time information that first depend on the important operational factor of electrical network links are controlled, and wireless sensor network, as " intelligent information perception tip ", can become the important technical promoting intelligent grid development." the sensor network research and development of the security monitoring of smart grid-oriented, power transmission efficiency, metering and user interactions and application verification " is classified as scientific and technological key special subjects problem by country, implement in full the large-scale application of sensor network in the field such as transmission of electricity, power transformation, distribution, electricity consumption of intelligent grid, sensor network technique will be used widely and develop in intelligent grid construction.
The places such as substation cable joint, blade contact, switch contact, copper bar tie point, reactor, arc suppression coil, capacitor, cable duct power cable may because of overload, fasteningly to loosen, the reason such as bad of dispelling the heat and cause heating.The running temperature of equipment is the important exterior representations of equipment running status, and according to running temperature, the information such as temperature rise, the alternate temperature difference can more whether judgment device duty be normal relatively.
Temperature monitoring data are important foundation data of repair based on condition of component, adopt the wireless temperature monitoring device that state's net letter is logical, can meet the technical need running temperature of the equipment such as major equipment of entirely standing, joint, power cable, capacitor, reactor being realized to on-line monitoring, in order entirely to stand, repair based on condition of component informationization provides basic data support.
The conventional mounting mode of wireless temperature-measuring sensor is subject to the query of owner unit for a long time in transformer station's practical application, and leaves potential safety hazard, be badly in need of a kind of safer, stable and easily mounting means change the status quo.
1, the application of wireless temperature-measuring sensor
1.1 wireless temperature measurement principles
Wireless temperature monitoring device passes through temperature rise, the different alternate temperature difference of the same equipment of Real-Time Monitoring of Real-Time Monitoring equipment under test versus environmental, realizes the automatic management of intelligent substation equipment running temperature, for the safe operation of intelligent substation provides Data support.System also can arrange various alarm temperature value for each measurement point respectively, and the temperature information of the measurement point that all running temperatures exceed standard, temperature rise exceeds standard has eye-catching prompting, conveniently patrols and examines work.The running temperature data of full station equipment are sent to electrical substation monitoring main control system by network, for the repair based on condition of component of substation equipment provides Data support.
Control to convert equipment under test temperature to digital signal by temperature sensor by the chip microprocessor of radio temperature sensor, read write line is passed to again by wirless transmitting and receiving module, by the temperature information that microprocessor will collect, upload to a PC computing machine by 485 communication modules.
Wireless temperature online detection system is primarily of (administrative center) main frame, data transmission base station and radio temperature sensor composition.
Radio temperature sensor to be usually directly installed near monitored equipment or on, each sensor has unique ID, will record monitoring point physical location during actual installation, and is recorded into together in host data base.
1.2 radio temperature sensor mounting meanss

1.2.1 structure glue is fixed
Spray proper catalyst at tested surface, the heat-conducting base of temperature sensor coats appropriate structure glue, pasted by sensor, light pressure 1 minute, can let go after adhesive solidification.
Structure glue fixed form is the modal mounting means of current switch cubicle radio temperature sensor, but is all subject to the query of Subscriber Unit for the reliability of structure glue all the time." only fixing a class electric device by glue? ", such query cannot be avoided, and practical effect need the checking of time and environment.
1.2.2 band is fixed
Namely the bottom surface of each radio temperature sensor is the thermometric face of sensor, this face is attached to testee surface, and is fixed on testee with nylon cable tie.
Band Stationary liquid, than the mode of structure glue, greatly promotes in reliability, but still there is hidden danger.One is the high temperature resistant situation of band itself, and whether two is in later stage maintenance process, can come off, lose.Band is fixedly difficult to close to equipment heating point in addition, and the temperature data gathered can not accurately reflect equipment situation.
1.2.3 bronze medal perforate is fixed
Copper bar opens M8 threaded hole, standard thread, and hole depth is greater than 10mm or penetrates copper bar.Horizontal level is placed in the middle, and upright position is near outlet cable joint but do not affect the dismounting (M8 threaded hole central point distance cable splice end is about 30mm) of cable splice.Sensor is directly screwed in copper bar perforate.
Copper bar perforate is the most firmly mounting means, but destroys the original structure of primary equipment, usually can not adopt by Subscriber Unit.
