10KV中压真空断路器的选用发布时间：2021-05-07T02:53:14.646Z 来源：《中国电业》（发电）》2021年第1期作者：景启刚[导读] 对中压等级的开断设备选型，被广泛应用，为10KV中压断路器选型的首选设备。

历电自动化科技（镇江）有限公司 21220010KV电压等级是我国配电的主要电压等级，10KV等级中控制开关中，真空断路器由于灭弧能力强，电气寿命长，维护方便，技术含量高等优点，在电力系统建设中，对中压等级的开断设备选型，被广泛应用，为10KV中压断路器选型的首选设备。

一、真空断路器的选择应按额定电流值和额定短路电流值进行选择，应以电网的实际容量为宜，尽可能地克服取值保险系数愈大愈好的倾向。

取值过大不仅造成大马拉小车极不经济的情况，同时也将影响开断小的感性或容性电流性能，导致截流过电压的发生。

据相关文献报导，我国运行中的10kV电网额定电流在2000及以下的约占总馈路数的93.1％，故而对额定工作电流的选择应以2000及以下为主。

对于最大短路电流值的选择应依据“城市网络规划与改造导则”的要求，避免盲目追求过大的保险系数。

目前国内市场上，主要选用的合资品牌断路器主要有施耐德HVX、ABBVD4、西门子3AE等品牌系列；自主品牌的有常熟开关CV1、上联RMVS1、宝光ZN172等系列。

产品质量现在自助品牌与合资品牌相差无几。

二、真空断路器及其特性断路器是带有特殊的灭弧室装置的一种开关电器，能够关合承载和开断正常回路条件下的电流并能关合在规定的时间内承载和开断异常回路条件(如短路条件)下的电流的机械开关装置。

适用于50Hz，3.6kV及以上电压等级的电网中，作为关合和开断负荷电流(一般不大于4000A)、过载电流及额定短路电流用(一般不大于63kA，亦可用作特殊场合关合和开断空载长线，空载变压器及电容器组等，以及在规定的时间内(1s、3s、4s)承载短路电流(一般不大于63kA，关合短路电流(一般不大于160kA)。
