    摘 要:研究不同頻率對(duì)氣體絕緣金屬封閉開(kāi)關(guān)設(shè)備 (GIS) 穩(wěn)態(tài)溫升特性的影響,對(duì)提高 60 Hz 條件下 GIS 的穩(wěn)定運(yùn)行具有重要意義。建立了 GIS 電-磁-熱多物理場(chǎng)耦合仿真模型,并考慮了接觸電阻和相間渦流效應(yīng)的影響,仿真計(jì)算了 50 Hz 和 60 Hz 下的生熱功率、溫度等分布,探究了不同頻率對(duì) 110 kV 三相共箱式 GIS 溫升特性的影響。仿真結(jié)果表明,60 Hz 下 GIS 的能量損耗比 50 Hz 下 GIS 的能量損耗增加了 4.62% ;GIS 在 60 Hz 條件下溫升相對(duì)于 50 Hz 有所升高,增幅在 3K 以內(nèi);相對(duì)而言,頻率對(duì)三工位開(kāi)關(guān)溫升的影響比對(duì)斷路器更為明顯。
    關(guān)鍵詞: 穩(wěn)態(tài)溫升;氣體絕緣金屬封閉開(kāi)關(guān)設(shè)備(GIS) ;頻率;多物理場(chǎng)耦合

    Abstract: It is vital to study the influence of different frequencies on the characteristics of the stable temperature rise of gas-insulated switchgear (GIS). The result could help improve the steady operation of GIS at 60 Hz.This paper constructed an electromagnetic heating coupling of the multi-physics simulation model, considered the contact resistance and the interphase eddying effect, calculated the distribution of heating power and the temperature at 50 Hz and 60 Hz, and explored the influences of different frequencies on the temperature rise characteristics of 110 kV three-phase common tank of GIS.The simulation results showed that the energy loss of GIS at 60 Hz increased by 4.62%. After comparison, the temperature rise of GIS at 60 Hz increased more than 50 Hz, and the amplification was under 3 K. Compared to the circuit-breaker, the influence of frequency on the temperature rise of the three-position switchgear is distinct.
    Key words: stable temperature rise; gas-insulated switchgear (GIS); frequency; coupling of the multi-physics
