汾西礦業(yè)集團(tuán)水泥廠地面變電所的設(shè)計(jì)
摘 要
本設(shè)計(jì)根據(jù)汾西礦業(yè)集團(tuán)下屬某水泥廠的電力負(fù)荷資料，做出了該水泥廠的35KV變電所的整體設(shè)計(jì)，包括負(fù)
荷計(jì)算及無功補(bǔ)償、系統(tǒng)主接線方案的選擇、高壓電氣設(shè)備的選擇、短路電流的計(jì)算及對所選的高壓電氣設(shè)備
的校驗(yàn)、繼電保護(hù)的設(shè)計(jì)、防雷及接地的設(shè)計(jì)等。本設(shè)計(jì)以實(shí)際負(fù)荷為依據(jù)，以變電所最佳運(yùn)行方式為基礎(chǔ)，
按照有關(guān)規(guī)定和規(guī)范，做出了滿足該水泥廠生產(chǎn)需求的設(shè)計(jì)。
設(shè)計(jì)中先對負(fù)荷進(jìn)行了統(tǒng)計(jì)與計(jì)算，選出了所需的主變壓器型號，然后根據(jù)負(fù)荷性質(zhì)及對供電可靠性要求擬定
主接線設(shè)計(jì)，考慮到短路對系統(tǒng)的嚴(yán)重影響，設(shè)計(jì)中進(jìn)行了短路電流計(jì)算。設(shè)計(jì)中還對主要高壓電氣設(shè)備做出
了選擇與計(jì)算，如斷路器、隔離開關(guān)、 壓開關(guān) 等。 還進(jìn)行了繼電保護(hù)以及防雷保護(hù)的設(shè)計(jì)和計(jì)算，
高了整 變電所的 性。

ABSTRACT
This is an overall 35KV substation design of a cement plant, which is affiliated
to the FenXi Mining Group. And the design is based on the statistics of the
cement factory. The design includes load calculation and reactive power
compensation, the choice of system main wiring scheme, selection of high voltage
electrical equipment, the calculation of short-circuit current and high voltage
electrical equipment of the selected calibration, the relay protection design,
the lightning protection and grounding design and so on. This design based on
the actual load, the substation optimal operation mode, the relevant regulations
and norms, is in accordance with the demand of the cement production.
Firstly, I collect the statistics and make calculation. Based on the calculation
result, I choose the main transformer model. Secondly, according to the nature
of the load and the power supply reliability requirements to formulate the main
wiring design, considering the influence of short circuit on the system, and in
the design of the short circuit current calculation. Besides, in the design of
the main high voltage electrical equipment has made the selection and
calculation, such as circuit breaker, disconnecting switch, low-voltage
switchgear, etc. And lastly, the design and calculation of the relay protection
and lightning protection, improve the security of the whole substation.
