Special Mic What is obstacle lighting and aviation disorder lighting lighting
1. Obstacle lighting
Install the lighting on the building for obstacles.Such as the flying obstacle logo on the top of the high -rise building, the navigation obstacle logo lamp installed on the buildings on both sides of the channel.Obstacle lighting should use lamps that can transmit red light. When installing obstacles, the following requirements should be met:
(1) General high -rise buildings only install obstacle lighting at the top, buildings with large horizontal area or intensive high -rise buildings, in addition to installing obstacles at its highest top, but also equipped with obstacle Lights on the top of its outside corner.Items
(2) The height of the chimney is more than 100m. In addition to installing obstacles at the top, an obstacle light should also be installed at a height of one -half.In order to reduce the degree of pollution of the barrier light at the top of the chimney, the obstacle light can be set lower than the 4-5m of the chimney mouth.In order to ensure reliability, the three obstacle Lights are generally installed into an equivalent triangle so that one of the obstacles can still see the light from the direction of the direction.
2. What are the aviation barriers
Aviation obstacles are special lamps that identify obstacles.The light -strong aviation obstacle light is Changliang. The mid -light strong aviation obstacle light and high -light strong aviation obstacle light are flashing. The flash frequency is not less than 20 times per minute and 70 times per minute.
Aviation obstacle Lights are generally divided into three types: low light, strong light, and high light strong. The vertical and horizontal distance between the aviation obstacle Lights is greater than 45 meters and its facilities. The three obstacle logo Lights can be used with each other.
A clear warning effect.
3. Under what circumstances must set up aviation barrier Lights
Aviation obstacles are special lamps that identify obstacles.The function is to show the outline of the structure, enabling the aircraft operator to judge the height and outline of the obstacles, and play a lamp in a warning function installed on the obstacle.
In order to distinguish the lighting Lights of general uses, the aviation barrier Lights are not often on but shiny. The low -light and strong aviation obstacle Lights are often on.It is less than 20 times per minute, not more than 70 times per minute.
Aviation obstacle Lights are generally divided into three types: low light, strong light, and high light strong. The vertical and horizontal distance between the aviation obstacle Lights is greater than 45 meters and its facilities. The three obstacle logo Lights can be used with each other.
A clear warning effect.
Situation 1: The high -protection of the airport is high or the ultra -high buildings and structures should be set up. All aviation obstacles and signs should be set up.
Situation 2: For artificial and natural obstacles that affect the safety of flight safety on the route and the flight area, aviation obstacles and signs should be set up.
Situation three: For the tall, tall buildings and facilities that may affect the safety of the flight, you should set up an aviation obstacle light and logo and pay attention to maintaining normal working conditions.
Fourth, setting distribution of aviation barriers
1. Obstacles The highest point and edge of the obstacle to the setting of the obstacle light (ie, the height and the width) of the obstacle.
2. If the top of the object is more than 45 meters above the ground on the ground, an obstacle light must be added to the middle layer.Consider the intermediate layer to add obstacles).When the building is equipped with an intermediate barrier light near the urban and residential areas, it should be considered to avoid making residents feel uncomfortable.It is generally required to see the light from the ground.
3. The obstacle lamps set up by the vast building complex should be seen from all aspects of the outline of the object. The horizontal direction can also be set at a distance of about 45 meters.
4. For 105 meters of ultra -high objects, facilities, or pull towers, roof tower, etc., the light -strong A -type obstacle light at the top should be set on its top, and the white flash should be set.lamp.
5. Ultra -high objects above 150 meters (such as radio and television tower, large crossing cable bridge, etc.) shall be set up at the top of the highlights and strong A -type obstacle Lights, and it should be used in conjunction with the middle and high -light strong obstacles.
6. The tower of the ultra -high voltage transmission wire should be set up with a high -light strong B -type barriers and a three -layer synchronous flash.The position of the tower is the minimum drooping point and the middle position of the two, and it needs to be located along the direction of the cable.
7. For chimneys or other similar buildings, the top obstacle light must be between 1.5-3 meters at the top. Considering the pollution of the chimney to the lamp, the obstacle light can be installed in the area below 4-6 meters (detailsSee the National Standard Festival).
8. Regardless of the obstacle light, the number and arrangement of the obstacles of the obstacles at different heights should be seen from the outline of the object or object group from all directions, and the synchronous flashes of the obstacle light should be considered to achieve an obvious warning effect.
