13、installation and maintenance of electrical systems for navi- gation aids, both visual and non-visual, are prerequisites for the safety, regularity, and efficiency of civil aviation. To this end, this manual provides guidance on the design and installation of electrical systems for aerodrome lighting
14、 and radio naviga- tion aids. The electrical systems for aerodrome lighting and radio navigation aids include features which are not usually involved in other electrical installations. This manual therefore discusses not only the general features of electrical practices and installations but also th
15、ose features which are of special significance for aerodrome installations . It is assumed that readers of the manual will be familiar with elec- trical circuits and general design concepts, but may not be knowledgeable of certain features of aerodrome installations which are less frequently encount
16、ered in other installations. It is important to note that the material presented in this manual is intended to complement national safety codes related to electrical installations. The nranual does not discuss electrical systems for buildings located on an airport other than the effect of such build
17、ings on total power requirements for primary and secondary power supplies. Similarly, the manual does not deal with the maintenance of electrical systems. For guidance on this latter issue the reader is-advised to refer to the Airport Servgces Manual, (Doc 9137), Part 9, Airport Maintenance Practice
18、s. Future editions of this manual will be improved on the basis of experience gained and of comments and suggestions received from users of this manual. Readers of this manual are invited to give their views, comments and suggestions to the Secretary General of ICAO. Copyright International Civil Av

28、inuous, disturbance- free electric power to operate properly. 2.3.4.2 UPS equipment. The uninterruptible power supply (UPS) system consists of one or more UPS modules, an energy-storage battery, and accessories as required to provide a reliable and high quality power supply. The UPS system isolates
29、the load from the primary and secondary sources and in the event of a power interruption provides regulated power to the critical load for a specified period. (The battery typically has a 151ninute capacity when operating at full load.) (See Figure 2-2.) a) UPS module. A UPS module is the static pow
30、er conversion portion of the UPS system and consists of a rectifier, an inverter, and associated controls along with synchronizing, protective, and auxiliary devices. UPS modules may be designed to operate either individually or in parallel. Copyright International Civil Aviation Organization Provid

A nonredundant UPS system is suitable for most operations. However, if the expense is justifi
32、ed, a redundant UPS configuration (see Figure 2-3) may be used to protect against module failure or very frequent primary power failures . c) UPS battery. The battery should be a heavy-duty industrial unit of the lead-cadmium type having an ampere-hour rating sufficient to supply direct current to t
33、he inverter as required by the UPS system manufacturers installation instructi0ns.r The battery is usually furnished with two-tier racks; however, where space is limited three- tier racks may be necessary. d) Remote alarms. The UPS equipment should be supplied with a remote-alarm panel to be install
34、ed in the operating space served by the UPS unit or in another continuously occupied room, such as a guard office. Since UPS equipment rooms are usually unattended; additional remote indicating devices should be provided to monitor the environmental control and fire alarm system of UPS module and ba
35、ttery rooms. e) UPS and battery room requirements. The UPS modules and their associated battery set should be installed in separate rooms. Construction should be of a permanent type. The wall separating the UPS module room from the battery room should be fireproof (1-hour rating). When feasible, spa
36、ce should be provided in the UPS module and battery rooms for the addition of future UPS equipment. f) Environmental control. Both the UPS module and battery rooms should be provided with an environmental control system to maintain the prescribed room conditions. Each environmental control system sh
37、ouldconsist of a primary system with a secondary system capability. Upon failure of the primary environmental control system, automatic transfer to the second- ary system should occur and should sound an alarm indicating the need for maintenance. 2.3.5 Special secondary power devices 203.5.1 Other s
38、econdary power devices which may be used for special facilities are standby battery power systems, with or without dc to ac inverters; photovoltaic or wind generators with battery systems and with or without dc to ac inverters; independent generating devices, such as thermoelectric, nuclear, or chem
39、ical fuel cells; and inertia-flywheel generators. The manufacturers information should explain the functioning and installations for using these devices. 2.4 VAULTS AND SHELTERS FOR ELECTRICAL EQUIPMENT 2.4.1 Shelters 2.4.1.1 Most electrical equipment or airport lighting and other facilities is loca
40、ted in vaults or special shelters for protection from the weather and for better security. Substations for high voltage are usually outdoors, and medium voltage distribution transformers are often pole mounted or placed on fenced transformer pads. Most electrical vaults are above ground and made of
41、fireproof materials.

44、 used in these vaults. The use of such materials reduce the hazard of electric shock, shorting of electrical circuits, and fire hazards Prefabri- cated metal structures are occasionally used as shelters for transformers and engine- generator sets. These vaults are used to house the power distributio
45、n and control equipment, secondary power equipment, and the various devices used to provide power and control for the airport lighting systems. These vaults should be of adequate size to contain the necessary equipment without crowding. These vaults may be divided into moms for better segregation of
46、 equipment and activities. 2.4.2 Loestion 2.4.2.1 Electrical vaults should not be located where they would infringe on obsta- cle limitation surfaces. The distances from the control tower to the vaults should be short enough to avoid excessive voltage drop in the control cables. The permissible leng
47、th of these cables varies with the size of the cable, the control voltage, and the types of control relays used, but some of the longer control systems limit the length of control cables to about 2 250 metres. Vehicular access to the vaults in all types of weather conditions is necessary and minimum
48、 conflict with aircraft traffic is desirable. The location should be convenient for connecting to the appropriate lighting circuits and facilities to keep feeder cable lengths as short as is practical. The vaults should be isolated from other buildings and facilities to prevent the spread of fires o
49、r explosions, except the shelters for secondary engine-generator sets may be near the electrical vault to reduce cable length and size and to simplify the power transfer system. Aerodsoaes with approach lighting systems may need separate approach lighting vaults for each approach lighting system. For major aerodromes, some authorities use a vault near each end of the runway or approa
