Demand Analysis
Major accidents such as conductor dancing, tower falling, wire breaking and insulator flashover caused by ice-covering have seriously threatened the stability and safe operation of the power system. At present, there is still a lack of in-depth research on the ice-covering calculation model, the scientific utilization of massive data for online monitoring so as to carry out research on the online assessment of ice-covering status, and the prediction of short-term development trend of ice-covering is still blank. Therefore, it is of great scientific significance to carry out the research on online monitoring of transmission line ice-covering calculation model, state assessment and prediction and warning, and it is a key technology that needs to be solved in the application of online monitoring of transmission lines.
Working Principle
Transmission line visualization mobile ice-covering monitoring technology using ice-covering measurement technology, can accurately measure the thickness of ice-covering, accuracy ± 1mm, the measurement accuracy will be greatly improved. Convenient installation, simple measurement principle, without changing the original structure of the line; monitoring device low temperature resistance, improve the online rate; charging unit with anti-snow, anti-icing, anti-wind and sand functions and SMS grading alarm function; can directly watch the wire ice-covered images; with a key melting function; integrated design, modular function, with good scalability, reserved for a variety of functional interfaces; with a set of monitoring devices According to the use of different environments and purposes can choose one or more functions, arbitrary collocation, greatly saving costs for users.
product features
1、Real-time image browsing (video): the camera is installed on the cross-stretcher, and the camera with low illumination can directly capture the image or video of the conductor and the analog conductor no matter in daytime or nighttime, so that it can directly observe the overlay on the analog conductor and the analog conductor.
can directly observe the simulation of the ice-covered conductor, so that the conductor ice-covered at a glance;
2, real-time data collection and information query and management: through the platform client to realize the monitoring data real-time data reading, historical sampling data query, real-time query and management of the state of the equipment.
The following chart shows the system status;
3、Visualization of battery management: systematic management of batteries Centralized management of front-end battery power consumption, timely adjustment of the system inspection task strategy to extend standby time, real-time charging and discharging status;
4、Three-level alarm: alarm according to the thickness of the ice cover, you can freely set the thickness of the ice cover for each level of alarm;
5, with optical fog: the camera uses for infrared band imaging special optimization of the lens, through the filter on the specific near-infrared band light to intercept, so as to use the fog in the infrared light
Imaging. Optical fog for fog penetration is very strong, the imaging effect is better;
6, anti-icing design: camera, micro-weather and other heating insulation layer design, when the temperature is lower than 4 degrees and simulate the growth of ice on the wire, the camera and micro-weather heaters began to
When the temperature is lower than 4 degrees and when there is ice growth on the analog wire, the heaters of the camera and micro-weather will start to work and dissolve the ice on the micro-weather and camera, so that the micro-weather and the camera can work normally under ice.
