        摘 要:氣體絕緣開關設備 (GIS) 和氣體絕緣輸電線路 (GIL) 產品的出廠電氣試驗通常是在總裝車間內進行的,根據某 1 100 kV GIS/GIL 總裝車間電氣試驗需求,設計了滿足工頻耐壓試驗、局放試驗及沖擊試驗的專用工裝。采用六氟化硫(SF6)氣體絕緣試驗變壓器和沖擊發生器降低了廠房高度,節約了廠房建設投資;為確定工頻電源補償容量,計算了計及試驗工裝后的負載電容電流,還利用 ATP-EMTP 評估了 GIS/GIL 工裝電容、電阻和電感對雷電沖擊試驗波形參數的影響,可供相關的試驗技術人員參考。

        Abstract: The electrical test of GIS/GIL is usually carried out in assembly workshop. Due to product assembly, inflation and standing time is long and electrical test time is short. In order to improve test efficiency, the manufacturers usually adopt the technological process of assembling multiple products at the same time and then to conduct electrical test one by one. Therefore, the design of special electrical test apparatus is particularly important. According to the electrical test demand of an 1 100 kV GIS/GIL assembly workshop, the special test apparatus is designed to meet the demand of power frequency withstand voltage test, partial discharge test and impulse voltage test. The SF6 type test transformer and impulse voltage generator are used to reduce the height of workshop and save the construction investment. In order to determine the compensation capacity of power supply, the load capacitance current considering test apparatus is taken into account and calculated. In addition, ATP-EMTP is used to evaluate the influence of GIS/GIL capacitance, resistance and inductance on lightning impulse test waveform parameters, which can be referred by relevant test technicians.
        Key words: gas insulated switchgear; test apparatus; partial discharge; electrical test
