新型双电源多备用插拔式低压开关柜的研制

Development of New Type of Dual Power Supply Multi-Standby Plug Type Low-Voltage Switchgear

传统的低压开关柜仅有一路低压电源,当出现配变、低压开关及高低压电缆故障时,需花费大量时间进行故障查找和修复工作才能使用户恢复供电。研发了一款"新型双电源多备用插拔式低压开关柜",该装置采用双电源进线,两路电源互为备用,有效避免了传统低压配电柜"故障即停电"的问题。采用模块化组装方式,故障抢修时拆卸和组装更加方便快捷。且箱体两端的U形把手和底部的万向轮方便人工运输,减少了作业强度,提高了作业效率。

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.
