As shown in Figure 1, between transformer station from power plant to terminal use, need to be connected by the power transmission line 1 of a large amount of towers 2 and long distance, the network that namely transducer in electrical power transmission system described in the utility model and Emergency Communications Network are made up of the transducer 3 be arranged in a large number on tower 2 and power transmission line 1.Fig. 2 is the topology diagram of sensor network, data communication is carried out by wireless network between adjacent sensors 3, a transducer can form mesh network with adjacent multiple transducers, instead of linear transmission one to one, to provide many data paths to control system 4.The utility model improves the reliability of wireless sensor network by arranging redundant path, when sensor network breaks down, the sensor network of redundant configuration is got involved and born the work of trouble unit, thus avoids suspension.
As shown in Figure 3, divide according to installation site, transducer 3 is divided into the line upper sensor 33 being arranged on tower upper sensor on tower 2 30 and power transmission line 1, line upper sensor 33 comprise near the nearly tower line upper sensor 31 of tower 2 and between adjacent two towers the tower line upper sensor 32 far away at middle part.According to be used for point, tower upper sensor 30 can arrange some large-scale measuring transducers, as for measuring tempeature, pressure, precipitation, humidity, wind speed, wind direction, airborne particle, salt granule density, the meteorological sensors such as solar radiation degree, and the transducer measuring that tower tilts; It is sagging that nearly tower line upper sensor 31 can be used for measuring power transmission line, transmission line icing thickness, line temperature and electric current etc., tower line upper sensor 32 far away is convenient to detection line vibration and distance overhead or between the trees of below, and these data are vital for the breakdown judge fallen in tower and flashover fault situation and monitoring.
A large amount of transducers 3 works for a long time under the field condition of meagrely-populated, bad environments, change the dangerous large cost of battery high, thus battery can not be only relied on to power to transducer 3, require that transducer 3 must be self-powered, and need self-contained electric system to possess high reliability and non-maintaining property.As shown in Figure 4, line upper sensor 33 of the present utility model is from the power taking of power transmission line 1 own, power pack 40 uses the alternating current transformation line as shown in US Patent No. 8437157 usually, i.e. power transmission line 1, power pack 40 comprises segmentation magnetic coil 41 and secondary coil 42, and such transducer can be installed under power failure or charged situation.Load current IL on power transmission line 1 will produce alternating current in secondary coil 42.A regulator rectifier circuit 43 changes alternating current into conventional direct current, and direct current is for charging to battery on line 47.On line, battery 47 powers to line upper sensor 33, microcontroller circuit 45 and transceiver 46.On line, battery 47 is for guaranteeing that sensor network can maintain normal work under powering-off state.Line upper sensor 33 measures transmission line performance and surrounding environment, and microcontroller circuit 45 processes transducing signal and by transceiver 46 and radio-frequency antenna, information is sent to communication network.
