Description
Technical field
The utility model relates to field of temperature measurement, particularly, relates to the equipotential temperature measuring equipment for power transmission line.
Background technology
Along with the fast development of national economy and the continuous expansion of city size, transmission line of electricity is more and more intensive, and running environment is increasingly sophisticated; Numerous transmission line of electricity is across highway, railway, bridge, river, lake and pass through high mountain, groups of building etc., and the safety of transmission line of electricity is more and more subject to the serious threat of various construction violating the regulations, the architecture against regulations, trees violating the regulations, floating thing and bird pest etc.
Transmission line of electricity in all parts of the country happens occasionally by outside destroy accident, as: scene, construction site to be in below transmission line of electricity or near, construction appliance (mainly the tall and big construction machinery such as crane, excavator, truck mixer) in operation, cause circuit to discharge to it in the safe range line that its tall outshot enters transmission line of electricity sometimes, even touch and be suspended to transmission line of electricity and cause tripping operation, power outage.And for example transmission line of electricity is when crossing highway, and due to vehicle super-high, transmission line of electricity lacks warning mark, causes transmission line of electricity to be damaged; Also have some transmission lines of electricity cross over rivers time, some large ships, the equipment such as dredger when at the incoming tide again non-cargo pass through below transmission line of electricity, its superelevation part causes the destruction etc. of transmission line of electricity.Also have some line crossings building or forest zone, the growth of trees and the effect of wind-force cause circuit to discharge not to the insulation distance of trees.
According to investigation, more existing preventing damage to power transmission line caused by external force devices are tried out in electric system at present, be divided into two kinds according to its installation site: one is fixed on steel tower, with laser ranging or tellurometer survey for ultimate principle, adopt solar panel and storage battery power supply; Another kind is installed on high-voltage conducting wires, based on ultrasonic ranging, adopts induction way to take power directly from wire, to obtain power supply.The span of 220kV transmission line of electricity is generally more than 200 meters, and the width between twice wires of multiple-circuit on same tower is greater than 15 meters, and the ground clearance of wire minimum point may be less than 10 meters; For the anti-outside destroy device be installed on steel tower, its distance measuring sensor is also installed on steel tower, and it wants the difference in height at 0.5 meter, measuring distance 200 meters of, requires that its vertical scan angle accurately reaches 0.2 degree.The wave beam of tellurometer survey antenna is difficult to accomplish within 0.5 degree, and bulky; Shaft tower wave and vibration can affect the work of laser scanning system, make it also be difficult to the vertical scanning precision of guarantee 0.2 degree; Further, the impact of laser distance measuring system (being worth lower than 100,000) climate is very large on a small scale, and under the weather conditions such as haze and cloudy day, the range finding distance that it can ensure is not more than 100 meters.Meanwhile, because the span between shaft tower is very large, circuit minimum point distance to the ground is relatively very little, and the trees of shaft tower periphery etc. form interference to the measurement of this kind of device, are easy to cause false alarm.The anti-outside destroy ball device be directly installed on transmission pressure generally adopts ultrasonic measuring distance technology, and be limited to the restriction of ultrasonic ranging distance, its conductor area that can protect is very limited.
Traditional transmission line of electricity supervising device such as video monitoring equipment etc. can only be arranged on iron tower of power transmission line, bulky, installs complicated; It adopts the power supply mode of sun power and accumulator.Because the setting angle of solar panels is undesirable, site pollution, continuously life-span etc. that is overcast and rainy and accumulator cause the poor reliability of this equipment, substantially reduce the serviceable life of equipment.Meanwhile, this kind equipment does not have measurement function, cannot position the object near transmission pressure, thus is difficult to carry out effective identification and accurately report to the police, cannot available protecting transmission line of electricity.
In sum, transmission line of electricity safety device by laser three-D range finding is and responds to based on power taking, be directly installed on need protection wire on, by laser quick three-dimensional scanning range finding, realizing take mounting points as the hemisphere region overlay of the centre of sphere; Different alarm distance values is set according to the position of every bit in hemisphere, realizes the protection early warning to rectangular region below wire.Its work is not tilted by shaft tower, vibrate, wave and the impact of trees etc. near shaft tower.Device obtains working power by induction mode, makes it also not by impact cloudy continuously.Compared to the system of employing large area solar cell array etc. being arranged on shaft tower, this device volume is small and exquisite, and in-site installation is simple, can run reliably and with long-term.
Traditional transmission pressure thermometric realizes mainly through infrared thermometer or thermal infrared imager, and not only equipment cost is high, and needs on-the-spot manual operation, cannot realize real-time monitoring.In order to not damage wires, need soft rubber to cushion, but avoid high-voltage conducting wires to discharge to equipment, need again metal to be electrically connected between transmission line of electricity device and wire, traditional wound copper establishment band mode not only inconvenient operation, also easily causes point discharge.Therefore need a kind of structure simple, temperature measuring equipment easy for installation solves the temperature survey problem of high voltage electricity transmission conductive wire, also solves the electric connectivity problem of equipotential of power transmission line monitoring device and wire simultaneously.
