Background technology
Due to factors such as the ANOMALOUS VARIATIONS of weather, cause China recent years high voltage transmission line icing phenomenon frequently to occur, icing, in increasing the weight of wire own wt, directly causes the electric power facility such as wire, shaft tower to occur damage in various degree, is having a strong impact on the people's household electricity and national economy.
China's electric power system in 2007 has now entered large capacity, ultra high voltage, the brand-new stage of long distance powedr transmission, the especially big ice damage in January, 2008 comes out the potential safety hazard of China's electrical network and auxiliary facility existence thereof completely, for the harmfulness of icing, is badly in need of a kind of safety, stable, low cost, low-power consumption, the practicable device of high effect escorts for national grid.But expensive, high power consumption that traditional de-icing method not only exists, complex structure, poor stability, need the shortcomings such as power-off, the personal safety that especially also may endanger staff in the time of the particular surroundings operations such as mountain region.
Summary of the invention
The utility model is exactly that cost is high in order to solve high voltage transmission line deicing difficulty, inefficient problem, and a kind of high voltage transmission line running status automatic monitoring deicing device is provided.
The technical solution adopted in the utility model: high voltage transmission line running status automatic monitoring deicing device, comprises
CT electricity taking coil group 1, for power taking from high-voltage fence;
Pressurizer 2;
Supervisory circuit element 3, for to monitoring-controlling system signal identification, transfer of data and for power-off;
Electricity is led and is surveyed ice sensor 4, and the icing on high voltage transmission line is detected;
Electric heating group 5, energising produces heat;
Wireless data transfer module 6;
Terrestrial wireless data reception module 7;
Wherein, CT electricity taking coil group 1 produces alternating current on high-voltage fence, alternating current passes to electric heating group 5 by supervisory circuit element 3 after pressurizer 2 and electricity is led survey ice sensor 4, electric conductivity value when electricity is led and surveyed ice sensor 4 and freeze on electrical network by measuring is judged the state of icing, the icing information detecting is passed to supervisory circuit element 3, supervisory circuit element 3 is identified icing information, while reaching icing limit value, supervisory circuit element 3 is connected to the voltage of electric heating group 5, lead and survey ice sensor 4 signal that deicing is completed and pass to after supervisory circuit element 3 when electricity, supervisory circuit element 3 is controlled 5 power-off of electric heating group, wireless data transfer module 6 receive real-time working status data from pressurizer 2 and supervisory circuit element 3 by fixed frequency range (2.4G frequency range) to be uploaded to supervisory circuit element 3 data messages, the operating state data that terrestrial wireless data reception module 7 sends from wireless data transfer module 6 by wireless receiving.
The utility model compared with prior art its beneficial effect is: the feature of the utility model low cost, low energy consumption, can realize electrical network do not have a power failure automatically monitoring, automatic defrosting, greatly improve the service efficiency of electrical network, this device can carry out Long-range Data Transmission simultaneously, realizes the real-time monitoring of ground centralized control center to electrical network.
Brief description of the drawings
Fig. 1 is Structure and Process schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, high voltage transmission line running status automatic monitoring deicing device, takes out AC220V and AC5V alternating current by CT electricity taking coil group 1 to high voltage transmission line, and wherein AC220V is controlled to electric heating group 5 and powered by supervisory circuit element 3 after pressurizer 2 voltage stabilizings.AC5V leads survey ice sensor 4 to after pressurizer 2 rectifications wireless data transmission unit module 6, electricity and supervisory circuit element 3 provides power supply.Electric conductivity value when electricity is led and surveyed ice sensor 4 and freeze by measuring is judged the state of icing, thereby transmits the whether information of icing of circuit to supervisory circuit element 3.Supervisory circuit 3 is led and is surveyed the signal of ice sensor 4 and identify electricity, once high voltage transmission line is while occurring that icing reaches 1～3mm, supervisory circuit element 3 is powered to electric heating group 5 immediately, starts ice-melt; Send after the signal having completed every ice until electricity is led survey ice sensor 4, supervisory circuit element 3, immediately to 5 power-off of electric heating group, finishes ice-melt.Wireless data transfer module 6 be by the operating state of stabilized voltage power supply group 2, supervisory circuit element 3 and malfunction by wireless mode (2.4G frequency range) earthward terrestrial wireless data reception module 7 transmission of centralized control center realize the time real monitoring to each device, once find that fault gets rid of in time.
