摘 要

工程為徐州市山水康橋2號樓電氣工程，本樓為一梯兩戶，一共有24層。本工程為二級負(fù)荷，供電電源均引自小區(qū)變電站，電壓等級為380V/220V，采用樹干式，供電供電電源引自小區(qū)內(nèi)變電站，住宅用電負(fù)荷為每戶8KW。
設(shè)計內(nèi)容包括強電和弱電設(shè)計兩個部分。其中，強電設(shè)計內(nèi)容包括配電系統(tǒng)設(shè)計、照明系統(tǒng)設(shè)計及防雷與接地系統(tǒng)設(shè)計；弱電設(shè)計包括有線電視系統(tǒng)設(shè)計、訪客對講系統(tǒng)設(shè)計、計算機(jī)網(wǎng)絡(luò)系統(tǒng)的設(shè)計、電話系統(tǒng)的設(shè)計及火災(zāi)自動報警系統(tǒng)的設(shè)計。
照明系統(tǒng)按環(huán)保節(jié)能標(biāo)準(zhǔn)設(shè)計，其中包括照度計算、燈具的選擇、照明干線、插座導(dǎo)線截面積的選擇以及導(dǎo)線的敷設(shè)方式。建筑物為第三類防雷建筑，防雷系統(tǒng)設(shè)計在屋面上裝設(shè)避雷針與避雷帶相結(jié)合的接閃器。有線電視系統(tǒng)采用分配分支方式，用戶輸出口信號電平為68±4dB。本工程為一類高層建筑，消防系統(tǒng)及部分重要負(fù)荷采用雙電源同時供電，電源由變電站引來，三相四線制。
關(guān)鍵詞：配電系統(tǒng)設(shè)計；照明系統(tǒng)設(shè)計；弱電系統(tǒng)設(shè)計；防雷接地系統(tǒng)設(shè)計

ABSTRACT

The project entitled Electrical Engineering design of Shanshui Kangqiao Building 2, this floor is a staircase 2, a total of 24 layers. This works for two loads, power supplies are drawn from district substation, voltage level for the 380V/220V, works with the trunk type, power supply power supply substations in the region cited a young age, household electricity load is 8 kW.
Design elements include electric and electronic design two parts. Among them, the strong electrical design include power distribution system design, lighting system design and the design of lightning protection and grounding system; weak design include cable system design, the intercom system design, computer network system design, telephone system design, fire alarm system design.
Lighting design by environmental and efficiency standards, including the illumination calculation, the choice of lamps, lighting, trunk, plug wires and wire cross-sectional area of the choice of laying mode. Lightning Protection for the third type of building construction, lightning protection system installed in the roof with lightning rods and lightning combination Jieshan Qi. Distribution of branches by way of cable television system, the user output signal level was 68 ± 4dB. Meet user requirements. This project for a class of high building, fire control system and some important load with double power and power supply, power substation, drew by three phase four wire.
Keywords: electrical system design；lighting system design；weak system design；lightning protection and grounding system design
