Description

双断口隔离开关模块 技术领域
本发明涉及220kV及以上电压等级的换流站/变电站的设备领域，更具体地说，涉及双断口隔离开关模块。
背景技术
隔离开关(俗称“刀闸”)，一般指的是高压隔离开关，即额定电压在1kV以上的隔离开关，通常简称为隔离开关，是高压开关电器中使用最多的一种电器，它本身的工作原理及结构比较简单，但是由于使用量大，工作可靠性要求高，对变电所、电厂的设计、建立和安全运行的影响均较大。隔离开关的主要特点是无灭弧能力，只能在没有负荷电流的情况下分、合电路。隔离开关用于各级电压，用作改变电路连接或使线路或设备与电源隔离，它没有断流能力，只能先用其它设备将线路断开后再操作。一般带有防止开关带负荷时误操作的联锁装置，有时需要销子来防止在大的故障的磁力作用下断开开关。
但随着电力技术的进步以及国民经济的发展，GIS产品在市场上依靠自身结构占地面积小，运行故障率低、重量轻、免维护等一系列优势得到越来越多的应用。
目前从国内外各大主流GIS设备厂家对于备用间隔扩建结构的设计来看，备用扩建间隔与运行母线中间只有一个隔离断口，因此在进行GIS备用间隔扩建安装以及交接耐压试验时均需对原运行母线进行停电处理，避免对接安装时隔离断口放电击穿造成的人身伤害，同时防止交接试验时隔离断口两端反向叠加过电压导致放电击穿的设备安全事故的发生。对于运行单位来说，协调变电站母线停电意味着工程进度的延误、人力物力的浪费以及停电带来的直接或间接的经济损失。据粗略估算，对于一个500kV变电站，停电一天的直接经济损失可达数百万元以上，更有一些变电站，由于上下游客户的特殊性，如大型冶炼工厂、重要政府机关部门等，导致协调母线停电的难度极高，严重影响工程的投运时间，间接造成巨大的经济损失。因此在项目招标初期，很多业主已经在GIS的技术规范书中明确：GIS备用间隔设计方案需满足在GIS在后期扩建过程中不停运行母线的要 求。
传统的GIS上使用的单断口隔离开关模块(DS：Disconnector Switch)将不适应于现今工业的需求。
综上，为满足GIS间隔扩建安装及交接耐压试验时不停母线停电的需求，急需设计一种新型的隔离开关模块，在实现扩建过程中以及交接耐压试验时原GIS运行设备不需停电过程中提供安全、稳定、可靠的开关模块，以满足对GIS间隔不停电扩建的需求。

通过简单紧凑的机械联动结构使双断口开关装置稳定、可靠。
