1fae=ingLiU summarizes the selection of the lighting type and the cross section of the lighting in the lighting design of the substation; the configuration of the light type. The choice of lamps and their arrangement; the number of lighting lines and related experience. Electrical lighting is not only related to optics and electricity, but also closely related to architecture and physiology, light and vision. Because substation lighting is related to the reliability of power supply, its design should be safe and advanced. economic. The principle of beauty, but also to meet the limit string light. It is convenient to maintain, etc. The following is intended to combine the author's many years of practice, to talk about how to enter the lighting design of the substation, the exchange of lighting 1 lighting method to determine the lighting style. Partial illumination and hybrid illumination H. The substation is controlled by the main control room and the protection room. In-house power distribution unit. Outside the distribution equipment and auxiliary buildings, the design of different places should be based on the actual needs of the 1.1 main control room. The protection room and the outdoor distribution device should adopt the general illumination. However, if the local illumination requirements of the outdoor distribution device are high, the illumination method combining the general illumination and the local illumination can also be adopted, that is, the hybrid illumination assistance 1.2 is used in the indoor distribution device. Hybrid lighting, so as to eliminate the dark and dark corners of the house, but also to meet the illumination of these places. 1.3 In the design, one place should be avoided to install only local lighting, because this will cause a lot of inconvenience to operation and maintenance. 2 lighting type selection Substation lighting can be divided into common lighting and accident lighting accident lighting including general accident lighting. Partial accident lighting and evacuation photos 2.1 Common lighting is installed in all places in the substation house, and is also installed in outdoor power distribution units and open spaces where people are active at night. It adopts the 380/¥ blue phase four-wire neutral point direct grounding system. The lamp voltage is usually powered by the internal station. If there are special requirements, it can also be powered by a dedicated transformer. 2.2 Accident lighting substation inside the main control room. Protect the distribution equipment in the Dong House. Accident lighting should be installed in places such as corridors and stairwells and evacuation passages. It uses V double-wire system, lamp voltage V, and W AC power supply automatically switch as the basic power supply mode, that is, AC power supply, when AC When the power supply fails, the accident lighting is automatically switched to the DC power supply. The lighting source of the 3 light source type configuration substation should be equipped with a good light, a white light, and a high-strength gas discharge good chair. Good metal chemistry, clever light and high pressure. Different places should be selected according to their requirements for lighting, the environment of the place of use and the characteristics of the light source. 3.1 control room like the use of lower color temperature white or warm white clever light as a lighting source, it is not appropriate to use a white and smart light mixed light source, avoiding the use of white light loyalty 3.2 indoor distribution equipment room like white traitor or high pressure Good as an illumination source, when the accident lighting is powered, a white light that can be ignited instantaneously and reliably should be used. 3.3 The external power distribution device uses high-voltage or mixed light as the illumination source. 3.4 In the same place, when the color color rendering of one kind of light source can not meet the requirements, the mixed light source of two kinds of light sources can be commonly used. The mixed light flux ratio of the light source can be selected by referring to the attached table. The mixed light flux of the mixed light source is lighter than that of the mixed light source. The color discrimination is better than the individual color. The other colors are good. Some of the colors are medium and outer, other colors are good except for individual tremors, and other colors are for the side. Note: 00 corpse light high and tired 00 pin lights; 0 key in the inside; "3 in the color high-pressure smart lights; 0 篼 light effect metal oxide lamps. 3.5 Where the ambient humidity is relatively low, it is not suitable to use the gas discharge light source with difficulty in starting. 4 The selection and arrangement of the lamps 4. Main control room 4.1.1 The main control room should be properly watched when selecting the lighting, but it is not suitable to install flowers. In the design, the embedded or ceiling-type smart light is generally used; for the large and medium-sized control room, the arrangement of the embedded or flame-retardant grid ray strip, light block or illuminating day 4.1.2 main control room should be used. The equipment is arranged side by side. As shown in Figure 2, the country 2 is a good axis of the axis. Because the smart light has two axes, there are two most suitable height-to-height ratios: AA wheelbase high ratio; BB wheelbase When the ratio is higher than Ll, the actual height ratio should be appropriately less than the maximum allowable value. 4.2 Indoor distribution equipment 4.2.1 Wall lamps or ceiling lamp holders are used for lighting fixtures in the indoor distribution equipment. Use the sweet white glass cover lamp for the operation corridor, maintenance corridor and busbar layer. The installation method should be ceiling or wall mounted. 4.2.2 The installation height of the lamps in the distribution interval is greater than 6, and the direct lighting fixture with concentrated sunlight is used. When the height is 6 o'clock, the wide-light deep-illuminated illumination tail is used. 4.2.3 When the installation height of the lighting fixture is low, the lighting fixture should have safety protection measures, such as wire mesh protection, 4.2.4 lighting and bare-belt with no fence. The safety distance of the conductor or equipment must comply with the provisions of the "Technical Regulations for the Design of High-Voltage Power Distribution Devices" to ensure the safety of the staff when replacing or wiping the lighting. 4.3 Outdoor distribution equipment 4.3.1 Install a round-shaped factory near the main transformer as the illumination of the main transformer section; appropriately set the floodlights or high-pressure lamps around the power distribution equipment site as the illumination of the entire site. 4.3.2 In the road lighting, the lighting poles are arranged in a single row, but in the entrance avenue, multiple rows of symmetrical or asymmetrical arrangements should be adopted in combination with the general layout and related requirements. 5 Lighting line conductor section selection The lighting line conductor section should be selected according to the line calculation current, according to the voltage loss. The minimum wire cross-section allowed by the mechanical strength is verified and should be matched with the power supply circuit protection device. 5.1 Conductor is selected according to the line cross-section: 1 wire allows the current carrying capacity, 1 lighting circuit calculates the current due to different temperatures at different temperatures. The calibration coefficient of the current carrying capacity should be checked according to the ambient temperature to avoid waste 5.2 indoor lighting circuit. The current of each phase loop should not exceed 16, and the number of connected circuits should not exceed 25 when it is connected. No socket should be provided in the accident lighting circuit. 5.3 Indoor lighting circuit wire is the choice of polychlorination gambling insulated wire. Type 6 lighting circuit laying substation lighting circuit is provided with two types of laying and dark laying, generally using dark laying. 6.1 The direction and arrangement of the lighting circuit should be considered in conjunction with the installation location of other electrical equipment, and avoid cross-cutting with the piping equipment of water, steam and fire protection systems. When drying 6.2 lighting lines are darkly laid, hard or semi-hard flame-retardant plastic pipes should be used. When the pipes are worn, the sum of the cross-sectional areas of the wires should be designed according to the 40-flavor not exceeding the cross-sectional area of ​​the pipes. Usually, the wires in one pipe The number should not exceed the 6.3 different voltage levels and the different lighting circuits of the conductors can not be co-management 6.4 external distribution equipment and bus bridges should not have lighting overhead lines through the end of the 7 substation lighting design is detailed, thorough Work, factors to be considered, a good lighting design should ensure the quality of lighting, reduce investment costs, and the use, maintenance and maintenance of convenience and safety. The development of high-temperature superconducting components processing new technology this superconducting engineering institute and NE The 3 companies jointly developed a new high-temperature superconducting component processing technology, which solved the problem of the performance unevenness caused by the high joint difficulty of Johnfson in the past. _ Research and improvement, "The thin and thin insulation layer will be put into practical use as soon as possible. structure. Long-term manufacturing technology is too difficult, resulting in uneven performance of the shadow component. When the research group used the ion irradiation method to etch and process the thin film, it was found that the surface of the lower superconducting film changed, and about 2 amorphous layers were formed. When the edge adjustment degree was improved and the upper thin film was laminated, the non-distribution was found. The crystal belly becomes an insulating layer, which becomes a stable and uniform component. This component is 100 times faster than the __ semiconductor component, and the power consuming device is one. This will be beneficial to the next century. The research group of the ultra-high-speed computer and communication high-energy switch will be put into practical use in 2002.
