Correlate standard、regulation and advise of setting the aviation obstruction lamps
(Accord with the international civil aciaton organization)
1、The ground and scope of the setting aviation obstruction lamps
《 the People's Republic of China civil aciation law 》 and interrelated document has specific regulation in setting the aviation obstruction lamps：
1、
Limiting high and exceed high building that in the airdrome heasroom protect area, need to setting the aviation obstruction lamps.
2、
The obstructionthat in and around the fairway that disturb the fly safe need to setting the aviation obstruction lamps.
3、
The rise floor 、 high building and establishment etc that may disturb the flying, need to setting the aviation obstruction lamps and need it to in the working state. * If there has parking apron that built for Police 、 fire fighting or traffic department and etc, the city's sky regards headroom, the high buiding in the city should set aviation obstruction lamps or the analogous symbol.
2、The relate standard、regulation and advice for aviation obstruction lamps.
《 civil airdrome flight area tachnic standard (MH5001-20000 》、 the inclosure 14 of 《 international standard and construct measure for airdrome 》 that issued by the international civil aviation organization and the People's Republic of China civil aciation calling standard 《 aviation obstruction lamps （ MH/T6012-1999) 》 has regulate that the aviation obstruction lamps setting by the obstruction must in flashing, in order to differentiate with the invariablenes that in the floor when in the sky look down .
( 1） the aviation obstruction lamps has three sorts that low light intensity, middle light intensity and high light intensity, if partition by the MH/6012-1999 and the the inclosure 14 of 《 international standard and construct measure for airdrome 》 that issued by the international civil aviation organization.
1. the low light intensity obstruct lamp is red flashing, the peak value light intensity over 32.5cd, general cooperate use with the middle light intensity and high light intensity.
2. the middle light intensity obstruct lamp is red flashing, the valid light intensity obstruct lamp is 2000cd ± 25% ， use for building and estabilishment that the high between the 90M --150M, or cooperate use with the high light intensity. 3. the high light intensity obstruct lamp is white flashing, the valid light intensity is100000cd ± 25% , main used to the building and establishment that the high over 150M. or cooperate used with middle light intensity obstruct lamp. ( 2 ) the setting of the aviation obstruction lamps
1 、 when setup the aviation obstruction lamps should point out the peak and edgeo of the obstruction.
2 、 If the peak of the obstruction is higher than 45M of the around area, must set the obstruct lamp in it, make sure the space between not over 45M. (the building in city that over 100M should consider set the obstruct lamp in the middle of the building.
3 、 the vast building group must set the obstruct lamp that make sure can make out the building figure in each angle, the level distance consider is 45m.
4. To the building 、 establishment etc that the high is between the 90m with 150m, should set the middle intensity obstruct lamp in the peak, is red flashing.
5. To the object that over 150m, should set high intensity obstruct lamp in the peak, and cooperate use with the low and middle intensity obstruct lamp.
6. The exceed high-handed transmit electricity iron tower should set high intensity obstruct lamp, and flash in three floor order . Setting in tower peak, the low-water mark of the cable and the middle.
7. To the chimney and homothetic building , the top obstuct lamp should in the top below 1.5-3m, consider the pollution of the chimney, the obstuct lamp can below 7.5m of the top.
8. whatever obstruct lamp, if have set it, should make out the object figuer in each angle , to attain the caution function.
1 、1 、 general buliding should set the obstruct lamp in the peak
2 、 to the buliding that the high between 90m with 150m, should set middle intensity obstruct lamp in the peak, and add obstruct lamp in the middle, and the best make the distance is the same.
3 、 The exceed high-handed transmit electricity iron tower should set high intensity obstruct lamp, and flash in three floor order . Setting in tower peak, the low-water mark of the cable and the middle.
4 、 To the object that over 150m, should set high intensity obstruct lamp in the peak, and cooperate use with the low and middle intensity obstruct lamp.
5 、 the vast building group must set the obstruct lamp that make sure can make out the building figure in each angle, the level distance consider is 45m.
6 、 The sketch map that set the obstruct lamp in the floor.
7 、 The sketch map that set the obstruct lamp in the peak of the building.
Notice: 1 、 When the obstruct lamp is on the pile or high-building, should be set in the protection area that around the 45 ° of the lightning road.
2、Such as electric net's electric wave is big, should bunch connect the calmed -pressure power supply.
