Description
技术领域technical field
本发明属于电力系统技术领域，具体涉及一种减少0.4kV封闭母线应急抢修工作时间的方法。The invention belongs to the technical field of power systems, and in particular relates to a method for reducing the emergency repair working time of a 0.4kV closed busbar.
背景技术Background technique
封闭母线：一种广泛用于发电厂、变电所、工业和民用电源的引线封闭式母线槽。它是由金属板为保护外壳、导电排、绝缘材料及有关附件组成。每隔一段距离设有插接分线盒的插接型接口。封闭式母线一般安装在地下室、电气竖井内，使用单一的中心母线系统向每层楼内供配电。Enclosed busbar: a lead-wire enclosed busway widely used in power plants, substations, industrial and civil power supplies. It is composed of a metal plate as a protective shell, conductive row, insulating material and related accessories. A plug-in interface for plugging in the junction box is provided at intervals. Enclosed busbars are generally installed in basements and electrical shafts, and a single central busbar system is used to supply and distribute power to each floor.
因为封闭母线是分段独立连接，且每一段为厂家依据现场土建实际情况而设计，采用独立的序列编码或工段号，不具备通用性，故没有预留相应的备品备件。一旦某段封闭母线发生故障损坏，只能将序列编码发回厂家定制、发货。等待配件多则1个月，少则10天，所以只能采取应急抢修、临时恢复供电的措施。Because the enclosed busbar is independently connected in sections, and each section is designed by the manufacturer according to the actual situation of the on-site civil engineering, it adopts an independent serial code or section number, which is not universal, so no corresponding spare parts are reserved. Once a certain section of closed bus fails and is damaged, the serial code can only be sent back to the manufacturer for customization and delivery. Waiting for accessories can be as long as 1 month, and as little as 10 days, so we can only take emergency repairs and temporary restoration of power supply.
应急抢修工作：电气设备发生故障，被迫紧急停止运行，需短时间内恢复的抢修和排除故障的工作。Emergency repair work: The electrical equipment fails and is forced to stop running urgently, and the repair and troubleshooting work needs to be restored in a short time.
根据“湖北营销业务应用系统生产库”查询统计，2014年精益化抢修中“0.4kV故障抢修平均用时”为68分钟，最长抢修时间为1356分钟。According to the query statistics of "Hubei Marketing Business Application System Production Database", the "average repair time for 0.4kV failure" in 2014 was 68 minutes, and the longest repair time was 1356 minutes.
按照优质服务的要求，应急抢修、恢复送电工作越快越好。In accordance with the requirements of high-quality service, the sooner emergency repairs and power transmission can be resumed, the better.
故障母线的长度最大只有8米，但现有的短接方案是从低压开关处用临时电缆接至电缆竖井内的电缆插接箱，实际展放电缆长度从100多米至300多米不等。“电缆施放用时”占“0.4kV封闭母线故障抢修时间”的63％。短接方案直接决定展放电缆的长度，对结果的影响程度大。The maximum length of the faulty busbar is only 8 meters, but the existing short-circuit scheme is to use temporary cables from the low-voltage switch to the cable plug-in box in the cable shaft. The actual length of the deployed cables ranges from more than 100 meters to more than 300 meters. "Cable deployment time" accounts for 63% of "0.4kV closed bus failure repair time". The short-circuit scheme directly determines the length of the deployed cable and has a great influence on the result.
由于封闭母线不具备直接连接电缆的功能，故每次故障点短接必须从低压开关处接至电缆竖井插接箱。对2014年更换的故障母线长度和临时短接电缆长度进行调查，实际故障母线不超过8米，临时短接电缆长度平均为253.3米。如果能够有效缩小短接距离，将有效减少0.4kV封闭母线应急抢修时间。Since the closed busbar does not have the function of directly connecting cables, the short-circuit of each fault point must be connected from the low-voltage switch to the cable shaft plug-in box. The length of the faulty busbars and temporary short-circuit cables replaced in 2014 was investigated. The actual faulty busbars did not exceed 8 meters, and the average length of temporary short-circuit cables was 253.3 meters. If the short-circuit distance can be effectively reduced, the emergency repair time of the 0.4kV closed busbar will be effectively reduced.
现场制作电缆终端头平均用时101.2分钟，也严重影响抢修工作时间。It took an average of 101.2 minutes to make cable terminals on site, which also seriously affected the repair work time.
