摘 要:為快速對(duì)繼電保護(hù)裝置、二次接線回路進(jìn)行合理、全面的檢修,并使檢修對(duì)正常運(yùn)行的其他設(shè)備產(chǎn)生的影響降到最低,提出了一種就地化保護(hù)裝置,該保護(hù)裝置采用無主分布式設(shè)計(jì),任一子機(jī)既可獨(dú)立運(yùn)行,又和環(huán)網(wǎng)中其他子機(jī)相互配合,集成過程層、間隔層設(shè)備于一體,接線方便、配置簡(jiǎn)單。以220 kV典型變電站為例,采用就地化保護(hù)裝置,屏柜數(shù)量降幅達(dá)60%以上,電纜、光纜使用數(shù)量大幅減少,建筑面積減少近50%,顯著提升了基建安裝的經(jīng)濟(jì)性,且減少了現(xiàn)場(chǎng)調(diào)試及運(yùn)維人員的工作量。
關(guān)鍵詞:就地化保護(hù);檢修;環(huán)網(wǎng);二次回路

Abstract: In order to fast make a reasonable and comprehensive overhaul for the relay protection device and the secondary wiring circuit and to make the impacts of the overhaul on other equipments of normal operation drop to the minimum, this paper proposed a kind of local protection device, which adopted the dereliction distribution design. Any one of the sub-machines operated independently and cooperated with other sub-machines in the ring network. This design integrated the process layer and the interlayer into the equipment with easy wiring and simple configuration. Taking 220 kV typical transformer substation for example, the local protection device was adopted to make the number of screen cabinet reduce to more than 60%, the number of cable and optical cable usage reduce dramatically and the area of structure reduce nearly 50%, which obviously promotes the economy of capital construction installation and reduces the workload of onsite debugging
and operation and maintenance personnel.
Key words: local protection; overhaul; ring network; secondary circuit
