1. The relevant regulations of the Civil Aviation Administration:
The National Civil Aviation Administration has made detailed regulations on the installation of solar aviation obstruction lights. Set up one or several solar aviation obstruction lights to help navigation safety. The obstruction light must be installed between 1.2m and 3m above the top of the building. If the building is more than 45 meters above the ground around the ground, an obstruction light must be installed on the middle layer. The position of the middle layer obstruction light shall be made as far as possible between the lights on each layer as much as possible, and low and medium intensity obstruction lights shall be used. The distance between them must not exceed 45 meters. (Set the number of lamp floors N = object height meters/45 meters) For large buildings, each corner of the building should be fully considered when setting the lamp, so that the outline of the building can be seen from each corner, and the horizontal direction Refer to the design requirements of ≤45 meters per floor. For tall buildings higher than 150 meters, high-intensity aviation obstruction lights must be installed at the top, and they must be used in combination with medium-intensity obstruction lights to show their existence. 2. Selection of various light intensity obstruction lights (H is the height of the building) 45 meters ≤ H ≤ 60 meters, using low-intensity GZ220-6, GZ220-7 obstruction lights 60 meters ≤ H ≤ 105 meters, using medium light Strong GZ220-7, 7B and GZ-155 type combined use 105 meters ≤ H ≤ 150 meters, use high and medium light intensity GZ220-7B and GZ-155 type combination use H ≥ 150 meters, use medium and high light intensity GZ-155 type The design of the lamp unit used in combination with GZ-90 requires the use of the GZ series long-life aviation obstruction light produced by Suzhou Haixiang Navigation Standard Electrical Equipment Co., Ltd. 3. The effective light intensity of the obstruction lights are as follows: 1) The effective light intensity of the low-intensity obstruction lights is 150cd, with red flashing or constant light. 2) The effective light intensity of the medium-intensity obstruction light is 1600cd, generally red flashing. 3) High-intensity effective light intensity 4000cd, generally white flashing (background intensity <50cd) 4. Lightning protection: 1) The top of the obstruction lights should be installed with lightning arresters, and the lightning arrester parts should be closely connected with lightning protection belts and other facilities. 2) The lamp in the middle of the building should be protected by a metal mesh cover, and the metal parts of the lamp should be well grounded.
Relevant standards, regulations and suggestions for the installation of aviation obstruction lights
(Consistent with ICAO) 1. Location and scope of aviation obstruction lights
"The Civil Products Aviation Law of the People's Republic of China" and relevant national documents have clear regulations on the installation of obstruction lights:
1. Aviation obstruction lights and signs should be installed on the height-limit or super-high buildings and structures for airport clearance protection.
2. The artificial and natural obstacles affecting flight safety on the route and around the flight area shall be set with aviation obstruction lights and signs.
3. For towering, tall buildings and facilities on the ground that may affect flight safety, aviation obstruction lights and signs should be set up and kept in a normal state.
★Public security, fire protection, transportation and other departments have built helipads in the city. The sky above the city is regarded as clear air. The tall buildings and structures in the city should be equipped with aviation obstruction lights and signs. 2. Relevant standards, regulations and suggestions for aviation obstruction lights
"Civil Airport Flight Area Technical Standards (MH51002000)", Annex 14 of "International Standards and Construction Measures Airports" issued by the International Civil Aviation Organization and "Aviation Obstruction Lights (MH/T6012-1999)", the civil aviation industry standard of the People's Republic of China. The obstruction lights have the following regulations: the aviation obstruction lights set up by obstacles must be flashing, so that they can be clearly distinguished from the constant light source on the ground when viewed in the air and can reach the specified long visual distance.
(1) Classification of aviation obstruction lights
According to MH/T60121999 International Civil Aviation Organization, "International Standards and Recommended Practices Airports" Annex XIV, obstruction lights are divided into three categories: low intensity, medium intensity and high intensity:
1. The low-intensity obstruction light is a constant light, red, and the peak light is stronger than 32.5cd. Generally, it is not used alone, but must be used in conjunction with medium-intensity and high-intensity obstruction lights. For example, the buildings and facilities above 45 meters are equipped with multi-layer medium-intensity or high-intensity obstruction lights, and low-intensity obstruction lights can be installed between the medium-intensity or high-intensity obstruction lights. (The low-intensity obstruction light is red, and the effective light intensity is 100cd±25%)
2. Medium intensity obstruction lights are divided into three types according to luminous requirements:
A, medium-intensity A-type obstruction lights are white flashes with an effective light intensity of 20000cd-2000cd, used for buildings and facilities above 105 meters and obstacles with strong background light or used with high-intensity B-type light dimming.
B, medium-intensity B-type obstruction lights are red flashes with an effective light intensity of 2000cd±25%, used in buildings and facilities below 105 meters or used in conjunction with medium-intensity A-type and high-intensity A-type obstruction lights.
3. High-intensity obstruction lights are divided into two types according to luminous requirements:
a. The high-intensity A-type obstruction light is a white flash, and it flashes at day, dusk or dawn and night with variable light intensity. The effective light intensity is 200000cd±25% in daytime; 20000cd±25% at dusk or dawn; 2000cd±25% at night ; Mainly used for buildings and facilities over 150 meters, or used in conjunction with medium-intensity obstruction lights.
b. The high-intensity B-type obstruction light is a white flash, and it flashes simultaneously at three levels of variable light intensity at day, dusk or dawn and night. The effective light intensity is 100,000 cd±25% in daytime; 20000 cd±25% at dusk or dawn; and at night. 2000cd±25%, mainly used for marking electric wires, cable towers and high-voltage transmission line towers. Third, the distribution of aviation obstruction lights
1. The setting of obstacles should mark the highest point and the most edge of the obstacle (ie, the apparent height and width).
2. If the top of the object is more than 45 meters above the surrounding ground, obstruction lights must be installed in the middle layer. The distance between the middle layer must be no more than 45 meters and equal as much as possible. Consider adding obstruction lights in the middle layer). When installing intermediate-level obstruction lights on buildings located near cities and residential areas, consideration should be given to avoid making residents feel uncomfortable. It is generally required that only scattered light can be seen from the ground.
3. Obstruction lights installed in large-scale buildings should be able to see the outline of the object from all aspects. The horizontal direction can also refer to the installation of obstruction lights at an interval of about 45 meters.
4. For 105-meter-long ultra-high objects, facilities or cable towers, roof towers, etc., a medium-intensity A-type obstruction light should be installed at the top of the object, with white flashing, and a red medium-intensity B-type obstruction should be set on the lower part of it. light.
5. Ultra-high objects higher than 150 meters (such as radio and television towers, long-span cable-stayed bridges, etc.) should be equipped with high-intensity A-type obstruction lights at the top, and medium and high-intensity obstruction lights should be used in conjunction.
6. Ultra-high-voltage transmission line towers should be equipped with high-intensity B-type obstruction lights, and the three-layer synchronous flashing should be provided. The location is the top of the tower, the lowest point of cable sag, and the middle of the two, and it needs to be located outside the tower along the cable routing direction.
7. For chimneys or other buildings of similar nature, the top obstruction lights must be located between 1.5-3 meters from the top. Taking into account the pollution of the chimney to the lamps, the obstruction lights can be installed 4-6 meters below the chimney mouth (detailed See excerpt from national standards).
8. No matter what kind of obstruction light, the number and arrangement of obstruction lights at different heights should be able to see the outline of the object or group of objects from all directions, and the synchronized flashing of the obstruction lights should be considered to achieve an obvious warning effect. Four, generally refer to the following obstruction light setting methods
Obstruction lights installed in large-scale buildings should be able to see the outline of the object from all directions. The horizontal direction can also refer to the installation of obstruction lights at an interval of about 45 meters. Generally, the obstruction lights should be installed on the top of the obstruction lights and objects higher than 150 meters are super high. , Set a high-intensity A-type obstruction light on its top, and use it in conjunction with a medium-intensity obstruction light. For tall objects higher than 105 meters but less than 150 meters, medium-intensity A-type obstruction lights should be installed at the top, and obstruction lights should be added to the middle layer, and the spacing should be as equal as possible.
Ultra-high-voltage transmission line towers should be equipped with high-intensity B-type obstruction lights, and flashing simultaneously for the three floors. The location is the top of the tower, the lowest point of the cable drop line, and between the two. Schematic diagram of floor installation of multiple inter-control flashing obstruction lights.
The National Standard of the People’s Republic of China GB50051-2001 stipulates the distribution and marking of aviation obstruction lights in the chimney. The control probe is controlled by an advanced computer microcomputer. Through the preset program software, it can automatically control any AC flashing obstacle lights to switch at the same time, flashing at the same time, and flashing directly or slowly. When there is no need to automatically control the switch, remove the light control probe, and it can be converted to manual manual control. The product quality is very stable, especially suitable for places with electromagnetic interference. It is safe and reliable to use, easy to maintain, and an alarm system can be added when needed.
