Solar power meter: new earthquake early-warning terminal side

Can let the plot gas cut off, the prevent post-earthquake fire; Compared with the prediction technique based on earthquake precursors, such as observation of ground stress, magnetism, etc. , and the earth resistivity based on the strong earthquake observation of earthquake early warning technology is actually used & other Run & throughout; Win seismic wave approach to provide early warning, in principle has higher reliability. （ File photo) Studies have shown that 3 seconds of warning time is available for indoor personnel find shelter, the personnel outside the building to avoid building, thus reduce more than 14% of the casualties; An earthquake incident, near the epicentre of the area affected by the earthquake time delay in turn. Therefore, earthquake early warning system installed in the power grid of substation monitoring sites, can maximize benefits while reducing earthquake monitoring site location and infrastructure costs. Modern life height of electrification, solar building grid system of earthquake damage not only cause serious economic losses, will seriously affect the earthquake disaster relief and recovery of production and life. And in the mode of implementation, the need to follow the scientific research, the heating system pilot and practical steps to implement the grid earthquake early warning. China electric science college in linyi uhv standing pilot application of the earthquake monitoring system. As early as in the last century, geophysicists study found that the seismic wave velocity in the strata generally within 8000 meters per second, and the destructive shear waves and wave propagation velocity within 5000 meters per second.

for a long time, the earthquake early warning as the important way to reduce the earthquake is a major concern. To this, the research and development in our country to implement the on-line monitoring system for substation earthquake, committed to in the grid system to carry out the earthquake early warning, and explore the key power facilities provide the earthquake early warning signal at the same time, also can provide the earthquake early warning service to the users of electric power. Therefore, in the transformer substation to set monitoring site and through the communication, communication system to carry out the early warning system has the advantage of high reliability. First of all, the distribution of the grid and height of the distribution of the national economy, large area power grid density and large area earthquake early warning requirements. 10 seconds of warning time for some people ran out of the building outside find refuge, and thus reduce more than 39% of the casualties; Scientific research stage to establish the setting method of earthquake monitoring substation, the pilot stage to examine municipal power grid is the right choice to carry out the earthquake early warning system for the pilot. Finally, on the basis of the successful practice in municipal power grid, the grid earthquake early warning technology popularization to regional power grid, the technology will really achieve the goal of increasing social disaster prevention ability. The graph is installed on the main transformer equipment of earthquake monitoring sites.

can automatic production line & other sensitive to vibration; The brake & throughout; Scrap, prevent damaged key equipment and products, and so on. Therefore, in the grid system to carry out the earthquake monitoring and early warning of ascension grid toughness is of great significance. If the number of seconds before an earthquake or tens of seconds, household electric meter can frequency different screeching alarm, prompts people to respond quickly to & ndash; — This short time, will become the gold window to reduce the earthquake casualties. More importantly, the popularity of smart meters for grid earthquake early warning system for public service provides a convenient terminal, can give full play to the early warning system of social values. Power plant operation of silicon 60 seconds of warning time more casualties can be reduced by 95%. Heating system, for example, early warning signal arrives, the smart meter output control instruction to the running of the elevator nearby safe place in the dock automatically, prevent personnel trapped inside the elevator?

smart meters as a warning, the terminal can send out sound and light alarm information, not only can realize the early warning signal and the linkage of the emergency operation. Thanks to the development of modern digital earthquake and communication technology, the earthquake early warning technology has become a reality. Monitoring system in our country has a large area of land in a seismically active seismic zone, it is necessary to strengthen earthquake prevention. Grid is an important part of lifeline earthquake engineering. Solar building power plants to monitor operating near the epicenter after the earthquake, the monitoring system for more than seismic wave propagation speed has not yet spread to place a warning signals, can achieve effective early warning. Silicon based on observation of earthquake early warning based on mandatory principle, the epicenter distance 20 km to 200 km range is the best area in earthquake early warning effect. The power grid system has a perfect infrastructure maintenance in our country, to achieve high reliability of power supply of 99. 9%. At the same time, the grid system for earthquake early warning has more technical advantages. Second, in the earthquake early warning system, monitoring site, data center and good maintenance of communication system is an important premise of system works in critical moment.
