制功率的流向和調(diào)整電壓的電力設(shè)施，作為電能輸送和控制的樞紐，設(shè)計(jì)是否合理，不僅直接影響了基建投資、運(yùn)行費(fèi)用和有色金屬的消耗量，也會(huì)反映在供電的可靠性和安全生產(chǎn)方面，它和企業(yè)的經(jīng)濟(jì)效益、設(shè)備人身安全密切相關(guān)。本設(shè)計(jì)主要介紹了 220kV 變電站電氣部分的設(shè)計(jì)。首先對(duì)原始資料進(jìn)行分析，設(shè)計(jì)主接線(xiàn)形式，選擇主變壓器的臺(tái)數(shù)及容量，綜合比較各種接線(xiàn)形式的特點(diǎn)、優(yōu)缺點(diǎn)，根據(jù)實(shí)際情況選擇兩種較其他方案可靠地主接線(xiàn)形式。再對(duì)這兩種方案進(jìn)行具體的經(jīng)濟(jì)、技術(shù)比較，然后選擇其中一種最合理的方案。對(duì)此方案進(jìn)行短路電流計(jì)算，為該設(shè)計(jì)中需 要的高壓電器設(shè)備的選擇、整定、校驗(yàn)等方面做準(zhǔn)備；繼而進(jìn)行主要電氣設(shè)備的選擇與校驗(yàn)，最后進(jìn)行配電裝置設(shè)計(jì)，防雷保護(hù)設(shè)計(jì)。 關(guān)鍵字 ：變電站 變壓器 電氣設(shè)備 配電裝置 II Electric preliminary design is primarily designed for 220kV substation hub Junfei Mi (Mechanical amp。 Electrical Engineering College of Shandong Agricultural University, Tai’an, Shandong 271018) Abstract substation on the production and distribution of electricity plays a key role in converting the power system voltage, receiving and distributing power, control power flow and adjust the voltage of the power facilities, power transmission and control as a hub, the design is reasonable, not only directly affect the investment, operating costs and capital consumption of nonferrous metals, will be reflected in the reliability and safety of power production, its economic benefits and business, it is closely related to personal safety design introduces the 220kV substation electrical part of the design. First, the raw data were analyzed, the main connection form design, select the number of units and the capacity of the main transformer, a prehensive parison of the characteristics of various wire forms, advantages and disadvantages, choose two reliable forms of landlord wiring than other programs in accordance with the actual situation. Then these two programs specific economic, technical parison, then choose one of the most reasonable option. This program shortcircuit current calculation in preparation for the design of select highvoltage electrical equipment, tuning, calibration, etc。 then select and check the main electrical equipment, the final distribution equipment design, lightning protection design. Keywords: converting station, transformer, electrical equipment, distribution equipment
