【正文】 ize but also highcapacity shortcircuit. enclosure size is a lot smaller than the original cabinets, circuit breakers without any oil, fire performance greatly improved. with a total of home and other lowvoltage equipment in a room, saving both space and convenience of management. The large volume of lowvoltage circuit breaker from the past, the development of small to large shortcircuit current capacity, the ability to continue to score small in size, stable, which makes the system more secure and reliable, and designed to bring the convenience. Intelligent direction toward another recent low voltage circuit breaker, breaker various parameters can be controlled through the bus industry, Signals transmitted to the puter directly. The emergence of drytype transformers, electrical design for the building posed a great convenience, Because there is no possibility of transformer oil spills and fires, so that it can be easily installed in the building itself, even go directly to the load center. It also eliminated restrictions on capacity building in the transformer oil, building greater capacity for drytype transformers can be used. In the designs of the project, on the application of four Taiwan2500kVA drytype transformers. Used emergency power generators, from the performance and size perspective,there is a lot of progress than in the past. In addition to the use of diesel generators works, as emergency lighting, we use EPS. Allowing a millisecond interruption in the supply of equipment, we can use UPS.Power equipment controlled from a single control to the control relay. Apart from the better performance of various ponents that are smaller in size and so reduce the volume control box, As a result of the digital technology is more controlled and controlled state control equipment at its best. further the energy saving effect. Lighting Project is a single source from the past, light lamps and the low efficiency of state toward even broader prospects. The light source used in the building are a number of varieties to choose from, toward a luminous efficiency of light, light color, develop in the direction of high colorrendering index, and lamps have been continuously improved its efficiency and allocationform so that the application of different example, the fluorescent lamp ballasts Inductance ballasts from the ordinary inductance ballasts to energysaving electronic ballasts. but also against the size of the harmonic ponents, to produce low harmonic electronic ballasts. Many technologies, accessories and lamps, can satisfy the design and design options, and fully meet the varied architecture, Lighting requirements for the various sites. Regardless of the lighting or indoor decorative or road lighting and outdoor courtyard of the building of light illumination, all of the show lighting technology to the development of the architectural lighting benefits and convenience. Another design used in electrical devices and other equipment, such as coswitching power supply switch of mutual investment. from the traditional production of specialized products,in addition to the conventional power switching meet, also a dual power supply can meet each other electronic equipment investment, greatly increasing the reliability and continuity of supply.Electric power supply cables and wires is widely used products. Look past the wire and cable samples, the species is scarce, and now, introducing various cable, From ordinary to the flameretardant PVC cables, fire resistance, Lowsmoke halogenfree cableradiation environment。 Bus Bus closed to regular insulation, precable, etc. branches. Electrical construction of these technologies are safe, reliable, convenient, providing an effective environmental protection. Targeting special needs of the construction of distribution, some new device has been widely applied. For example, large hospital operating room medical establishments leakage protection, residual current monitoring system.The development of the technology for strong, and it is obvious to the engineering and technical personnel, as well as our own experience. Such a great development for China39。 1990s, the civil Lighting Design Standards GBJl3390。civil Electrical Design Standards Lighting design standards of industrial enterprisesGB5003492。 Supply and Distribution System Design Standards GB5005295。Low Voltage Distribution Design Standards GB5005495。 GB5005794 Building mine design,
