(1) According to local customs and climate characteristics, divide the key periods of mountain fire prevention. The high incidence of mountain fires mainly includes Spring Festival, spring ploughing, going to graves to worship ancestors (Qingming, Central Plains, winter solstice and so on). ),? Straw burning (summer harvest, autumn harvest), other special (frequent festivals of mountain fires, continuous sunny, hot and dry weather, etc. ) and so on. For key road sections and key time periods, the passage shall be patrolled no less than 1 time every day, and the line inspector shall patrol continuously every day. For important transmission channels, people should be on duty 24 hours a day.
(2) Based on the line patrol, investigate and count all kinds of fire hazards in and around the protected area that may cause transmission line faults, sign safety agreements with relevant management departments, units and individuals, and establish files.
(III) For forest farms, buildings, structures and illegally stacked inflammable and explosive articles with fire hazards in and around the protected area, a Notice of Safety Hazards shall be issued to the relevant administrative departments, units and individuals, specifying the rectification requirements and eliminating the safety hazards within a time limit.
(4) Strengthen patrol inspection of the hidden dangers that have issued rectification notices, and urge relevant units and individuals to rectify within a time limit until the hidden dangers are eliminated; In view of the units and individuals that have great fire hazards but refuse to rectify, the joint government power facilities management department will stop power supply and punish them according to law.
(5) In special seasons and special time periods such as strong wind in spring, high temperature in summer, and "Tomb-Sweeping Day" sacrifice, special fire patrols will be conducted on key parts such as forest farms, garbage dumps, waste collection stations, timber factories and villages around the line to check the implementation of wind and fire prevention measures.
(6) Strengthen the operation, maintenance and management of transmission line channels. Trees and weeds around the tower and in the line corridor should be cleaned up, and trees that do not meet the specified requirements in the line corridor should be resolutely cut down.
(7) Comprehensively clean up the inflammable and explosive articles piled up in the line protection area, publicize the hazards of fire to the line and the serious consequences caused by residents who often pile up haystacks, grains, sugarcane leaves, etc. Offline, and asked to move.
(8) The occurrence of mountain fires is greatly influenced by the custom of using fire in industry and agriculture in the field, and the transmission lines pass through mountainous woodlands, shrubs, thorns and farmland. Therefore, there are serious hidden dangers of mountain fires. The prevention of mountain fires highlights six technical measures: avoidance, resistance, improvement, planting, cleanliness and innovation.
? 1) "Avoidance": Transportation inspection departments and line inspection units at all levels participate in the feasibility study, evaluation and route selection of the new line, and urge the line to avoid mountain fire-prone areas such as forest areas, bamboo forest areas, multi-grave areas, densely populated areas and agricultural habitual burning areas as much as possible, and implement measures to avoid hidden dangers of mountain fires.
? 2) "Resistance": Transportation inspection departments and line inspection units at all levels participate in the preliminary design review and project acceptance of new lines, supervise the implementation of high-span design to prevent mountain fires, improve the removal standards of trees and bamboos in important transmission channels, and enhance the ability of lines to resist mountain fires.
? 3) "Renovation": The line inspection unit, in combination with the operation experience, conducts the investigation of hidden dangers on the line, and takes technical renovation measures such as hardening, lowering the foundation, heightening the tower and diverting the road for the line sections with hidden dangers near the conductor that do not meet the requirements for preventing mountain fires.
? 4) "Planting": For the line section passing through the fast-growing forest area, the line inspection unit should negotiate with the local forestry department or the householder, take measures such as forest subletting and vegetation replacement, plant fire-resistant trees outside the line passage to form a biological fire barrier, and if necessary, build a fence or cut down the fire barrier synchronously with the forestry department. Replace flammable and fast-growing plants with low-nonflammable cash crops in line protection areas.
? 5) "Cleaning": The transportation and inspection department shall, according to the landform, vegetation types and relevant technical requirements of the line, formulate differentiated channel cleaning standards according to the importance of the line, and implement capital investment. In accordance with the standards of channel cleaning, investigate the hidden dangers of channels, and establish archives of key road sections and prevention and control measures for mountain fires.
? A capital investment: transportation and inspection departments at all levels and line transportation and inspection units should ensure the capital investment in channel cleaning, give priority to channel cleaning as an overhaul technical transformation project, and independently raise funds to ensure the implementation of channel cleaning when there is a gap in channel cleaning expenses, as shown in Figure 5-26.
? B. Personnel input: The channel cleaning is carried out in various ways, such as cleaning by the line patrol unit itself and entrusted by the local power supply company, outsourcing enterprise, line patrol and information officer, so as to ensure the full input of personnel.
? C. Cutting down trees and bamboos: The line inspection unit shall formulate standards for cutting down trees and bamboos, cut down trees and bamboos in time and transport them away from the traffic site to ensure the cutting efficiency.
? D. Shrubbery and thatch cleaning: The patrol unit strictly implements the channel cleaning standards and cleans the shrubbery and thatch in the channel in time. As shown in the following figure, the number of times of preventing mountain fires and clearing obstacles is appropriately increased during particularly sunny and hot periods.
? E. Setting up a wall: The line patrol unit should clean up the bamboo area under the transmission line and build a wall, and clean up the newly grown bamboo shoots in the wall in time every spring to prevent the bamboo from continuing to grow.
? F. Setting up mountain fire isolation belt: If necessary, cut down the mountain fire isolation belt, actively seek government support when cutting down the isolation belt, and cut down synchronously with the forest fire isolation belt.
6) "New": Transportation inspection departments at all levels and line transportation inspection units explore and popularize new technologies such as mountain fire monitoring and new fire fighting equipment.
? A. Video monitoring: A video monitoring device for mountain fires is installed in the high-incidence area of mountain fires, and the monitoring images can be observed in real time by using the computer terminal. When there is a suspected mountain fire, the system will automatically alarm to remind line maintenance personnel to take precautions.
? B. Artificial rainfall: artificial rainfall is used to increase the vegetation humidity in the high-incidence period and high-incidence area of mountain fires to prevent the occurrence of mountain fires; Or after the mountain fire, use artificial intervention in rainfall to put out the mountain fire.
? C. Fire lookout: establish a fire lookout in the high-incidence area of mountain fires, and monitor the mountain fires by manual stationing. If a mountain fire is found, notify the line maintenance personnel to take relevant emergency measures as soon as possible.
? D. First fire extinguishing by mountain fire: The first fire extinguishing by mountain fire should be carried out in high-time and high-frequency areas in the early stage of ensuring safety, and the configuration of fire prevention equipment should be reasonably arranged and unified. In the provinces prone to mountain fires, every important transmission channel? 100 km configuration is not less than? 1 set of large-scale mountain fire prevention equipment, and the configuration of the operation and maintenance team for the high and medium risk sections of mountain fires shall be no less than? 3 sets of small mountain fire prevention equipment. Cross-regional lines are configured as required according to the historical fire density, line importance and historical mountain fire trip of the line corridor.
(9) Establish and improve the emergency plan to ensure that personnel, vehicles and equipment are in place. Strengthen contact with fire, public security and forestry departments. When a mountain fire occurs, immediately take the initiative to contact the local government, police and fire forces to organize fire fighting in time. ?
(10) Make systematic prediction, monitoring and early warning to prevent mountain fires.
1) Mountain fire prediction means that the monitoring and early warning center carries out short-term and medium-term mountain fire prediction and issues a report during the high incidence period of mountain fires. The medium-term forecast of mountain fire refers to the prediction of the possibility (probability) of mountain fire near the line in the next 7 days; Short-term prediction of mountain fire refers to the prediction of the possibility (probability) of mountain fire in the next three days.
2) Mountain fire monitoring refers to the work of satellite monitoring on duty, satellite data reception, hot data analysis and identification in the monitoring and early warning center. The monitoring and early warning center conducts satellite monitoring of mountain fires every day, and implements 24-hour satellite monitoring duty during the high incidence period of mountain fires. Through the satellite monitoring system of transmission line mountain fire, the duty officer monitors the transmission line mountain fire in the provinces with high incidence of mountain fire in the State Grid in real time; The provincial equipment state evaluation center carries out the corresponding duty work through the customer access terminal or the provincial mountain fire monitoring substation system; The monitoring and early warning center calculates the fire alarm monitored by the satellite monitoring system in real time, and releases the fire alarm information to the provincial equipment condition evaluation center or line operation and maintenance personnel by telephone or SMS.
? Level 1 alarm: the distance between the hot spot of mountain fire and the line is less than or equal to 500m m.
? B secondary alarm: the distance between the hot spot of mountain fire and the line is more than 500m and less than or equal to 1000m.
C level 3 alarm: the distance between the hot spot of mountain fire and the line is greater than 1000m and less than or equal to 3000m m.
D. No alarm: the hot spot of mountain fire is more than 3000m away from the line.
? 3) Mountain fire early warning work includes the determination of mountain fire early warning level, short-term and medium-term mountain fire forecast, mountain fire early warning suggestion and power grid early warning release. The monitoring and early warning center regularly carries out short-term and medium-term mountain fire forecast in high-incidence period, compiles short-term and medium-term mountain fire forecast conclusions and mountain fire early warning suggestions for cross-regional power grids of State Grid and provincial lines, and reports them to the National Network Transportation Inspection Department and the Operation and Maintenance Department of provincial companies; According to the mountain fire monitoring and early warning suggestions, the provincial company issued a mountain fire warning to the power grid according to the feedback of wild mountain fires; The transportation and inspection unit shall, according to the early warning of mountain fire and the actual situation of mountain fire on the spot, take corresponding measures in time.
A. Warning level: The warning level is red, orange, yellow and blue from high to low.
B. Red warning: the number of monitoring hotspots in a province on the same day is greater than or equal to 300.
? C. orange warning: the number of monitoring hotspots in a province on the same day is greater than or equal to 200 and less than 300.
? D yellow warning: the number of monitoring hotspots in a province on the same day is greater than or equal to 100 and less than 200.
? E. blue warning: the number of hot spots monitored in a province on the same day is greater than or equal to 50 and less than 100.
? F. No early warning: the number of mountain fire monitoring points in a province on that day is less than 50.
I hope the above can meet your requirements.
