摘 要：傳統(tǒng)的低壓開關柜僅有一路低壓電源，當出現配變、低壓開關及高低壓電纜故障時，需花費大量時間進行故障查找和修復工作才能使用戶恢復供電。研發(fā)了一款“新型雙電源多備用插拔式低壓開關柜”，該裝置采用雙電源進線，兩路電源互為備用，有效避免了傳統(tǒng)低壓配電柜“故障即停電”的問題。采用模塊化組裝方式，故障搶修時拆卸和組裝更加方便快捷。且箱體兩端的U形把手和底部的萬向輪方便人工運輸，減少了作業(yè)強度，提高了作業(yè)效率。
關鍵詞：雙電源；備用；插拔式；開關柜

Abstract: The traditional low-voltage switchgear has only a low-voltage power supply. When there is a distribution transform, low-voltage switch and the high & low voltage cable faults, the personnel needs to spend a lot of time on trouble shooting and repairing work, so as to restore the power supply for users. This paper developed a new type of dual power supply multi-standby plug type low-voltage switchgear. This device adopted dual power supply incoming line. The two power supplies were alternate to effectively avoid the traditional low-voltage power distribution cabinet "failure blackout" problem. The device adopted modular assembly method, so that it was more convenient to disassemble and assemble during repair, in addition, the u-shaped handles at both ends of the box and the universal wheel at the bottom were convenient for manual transportation, which reduces the working strength and improves the working efficiency.
Key words: dual power supply; standby; plug type; switchgear
