本申请基于申请号为201910828552.4、申请日为2019年09月03日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及一种柔性直流换流阀阀塔。
背景技术
目前，直流配网具有提高电容量、减小线路损耗、改善用户侧电能质量、隔离交直流故障，以及可再生能源灵活、便捷接入等一系列优点。在柔性直流配网工程运行过程中，换流阀是整个柔性直流配网系统的核心部分，在功能上起到联接交流系统和直流系统的关键作用，实现交流和直流能量的相互转换，其良好的运转能力是整个系统能量传输的最根本保障。
现有的换流阀由于所需数量极多，多以阀塔形式存在，其结构如授权公告号为CN204761307U的中国实用新型专利中公开的换流阀阀塔，包括上下分层布置的阀塔单元层，每个阀塔单元层均包括多个阀组件，每个阀组件分别包括多个子模块以及分支水管，装配时，各阀组件的分支水管对应与主水管连通，分支水管与子模块连接以实现对子模块的冷却。使用时，利用阀塔底部的支柱绝缘子支撑在地面上，并将阀塔接入交直流换流系统中即可。
实际上，一般的换流阀阀塔多是支撑布置在阀厅中，阀体上的阀组件作为功能器件也时直接暴露在阀厅中的，由于阀组件上的压力通常较高， 为避免出现意外事故，阀厅内通常不配置巡检人员，而是利用给自动巡检设备进行巡视检查的。这种巡检方式需要配置较多的感应检测器件，一旦个别感应检测器件出现故障，必然会引发意外事故，考虑到精度及可靠性，巡检设备成本通常较高，对于级别较高的换流阀来讲，巡检设备成本占据总成本比重相对较小，能够接收，但是对于较低电压的换流阀来讲，巡检设备成本占据总成本的比重较大，变相推高了整个换流阀系统的成本。
发明内容

具体实施方式
下面结合附图对本发明实施例的实施方式作进一步说明。
本发明所提供的柔性直流换流阀阀塔的具体实施例，如图1至图5所示，该实施例中的换流阀阀塔包括阀塔本体10和阀塔罩壳1，阀塔罩壳1对应罩设在阀塔本体10外侧，以起到防尘防护作用，同时，利用阀塔罩壳1封装阀塔本体10的方式，使得巡检人员能够在阀塔运行状态下进入阀厅进行巡视，便于巡检人员对带电运行阀塔的实时抵近监控。
阀塔本体10的底部固定设置底部绝缘支撑，具体为底部支撑绝缘子15，以将阀塔本体10支撑固定在相应基础地面上。阀塔本体10包括沿上下方向间隔布置的三层阀塔单元层，各阀塔单元层分别包括三个沿左右方向依次布置的阀组件11。实际上，相邻阀塔单元层之间利用层间支撑绝缘子13进行支撑，层间支撑绝缘子13上下两端分别固定装配有支撑梁14，对应的阀组件11与支撑梁14固定装配在一起，进而利用底部绝缘支撑15、层间支撑绝缘子13、支撑梁14及阀组件11形成阀塔本体10的主要部分。
阀组件11的结构如图5所示，阀组件11包括组件框架102，组件框架102上沿左右方向对应安装有七个子模块101，还设有沿左右方向延伸的阀组件分支水管104，阀组件分支水管104通过功率模块分支水管103对应与子模块101连通。无论是阀组件分支水管，还是功率模块分支水管均为分支水管，分别包括对应的进水分支水管和出水分支水管，以在阀组件分支水管与相应主水管17连通时，实现对子模块的水循环冷却。
装配时，组件框架102与支撑梁14固定装配，并对应各阀塔单元层，将阀组件分支水管104连接起来并与主水管17连通，因为阀组件分支水管是固定在子模块上的，所以，通过与各阀塔单元层的阀组件分支水管的固 定装配，即可将主水管17也对应的固定装配在阀塔本体10上。当然，主水管也对应包括进水主水管和出水主水管。为方便布置，将进水主水管和出水主水管对应布置于阀塔本体的左右端部的一端。
另外，在阀塔本体10上还固设有外接端子，外接端子具体包括直流侧铜排16、交流侧铜排12、用于接入阀塔光纤及二次线的阀塔光纤及二次线接口端子2，以满足阀塔本体的正常使用。
为实现防尘以及隔离阀塔本体，在阀塔本体10外侧罩设有阀塔罩壳1，阀塔罩壳1接地以保证安全。同时，为保证阀塔本体的正常工作，在阀塔罩壳1上对应上述的主水管17、外接端子等分别设有过孔3，而且，为方便检修，阀塔罩壳1还包括可开启的检修门板4。由于阀塔罩壳的隔离作用，在利用阀塔罩壳将阀塔本体与外界隔开时，使得巡检人员可直接进入阀厅进行抵近巡检，在需要维护检修时，将阀塔本体断电，打开检修门板，即可直接进行检修。因为整个阀塔罩壳为整体上为长方体结构，其长边沿左右方向延伸，短边沿前后方向延伸，为方便对各单元层进行维护检修，在阀塔罩壳1的前侧面和后侧面上分别设有多个沿左右方向依次布置的检修门板4。
实际上，对于阀塔本体来讲，主要依靠冷却水对子模块进行循环冷却，为进一步提高散热效果，在阀塔罩壳1上设置散热孔8。具体的，因为整个阀塔罩壳具体包括固设在阀体本体四周的框体骨架，以及安装在框体骨架上的固定面板和检修门板4，为方便安装，通常将散热孔8设置在检修门板4上，这样可以将检修门板集中制作，简化生产工艺。
另外，对应检修门板设有门控开关，门控开关可设置在阀塔罩壳1上或设置在检修门板上，门控开关用于检测检修门板的开启状态，当检修门板开启时，门控开关的辅助触头将电信号传输至后台控制器，有相应的后台控制器对整个阀塔进行高压断电操作，以避免出现带电开启而带来的事 故，这样一来，即便是误开启检修门板，能控制阀塔断电，以保证巡检人员的人身安全。
实际上，在检修门板4上安装有电磁锁9，该电磁锁用于锁止检修门板，当柔性直流换流阀阀塔带电时，带电显示灯亮起，同时，带电辅助处点断开，电磁锁线圈失电，电磁锁处于锁止状态，检修门板不能开启，防止带电误入高压设备。当阀塔失电时，带电显示灯熄灭或闪烁，此时，带电辅助触点的常闭点接通，电磁锁线圈得电，电磁锁打开解锁，检修门板可正常开启。
整个换流阀阀塔在装配时，按照施工图将底部支撑绝缘子15定位安装在基础地面上，并在对应的底部支撑绝缘子15上固定安装支撑梁14，然后用电动葫芦将预装好的阀组件11对应吊装在支撑梁14处，先将第一层的四个阀组件吊装完毕，然后依次安装层间支撑绝缘子13及支撑梁14，继续吊装第二层的四个阀组件，继续安装层间支撑绝缘子13和支撑梁14，继续吊装第三层的四个阀组件。对应各阀塔单元层，将四个阀组件的阀组件分支水管104对应连接起来，并将对应的主水管17与阀组件分支水管104固定连接。同时，将各外接端子对应的固定安装在阀塔主体上。
最后在阀塔主体的外侧设置框体骨架，在框体骨架上设置固定面板5及检修门板4以形成阀塔罩壳1，并利用阀塔罩壳1上的相应过孔3满足主水管、外接端子与外界的连接要求，保证整个阀塔正常工作。
本实施例所提供的换流阀阀塔中，阀塔罩壳罩设在阀塔本体外，以将阀塔本体与外界隔离，但是其也会受到阀塔本体的影响，所以这种阀塔罩壳适合应用在级别不高的阀塔上，例如电压等级为±10Kv，电流等级为1000A。
上述的框体骨架具体可拼接组装而成，组装而将相应的固定面板和检修门板安装在框体骨架上即可。
一实施例中，阀塔本体的结构如图4所示，阀组件的结构如图5所示，在其他实施例中，阀塔本体及阀组件的结构可采用授权公告号为CN204761307U的中国实用新型专利中公开的阀塔及阀组件。
一实施例中，阀塔本体为长方体结构，阀塔罩壳也为长方体结构，在其他实施例中，阀塔主体如果为正方体或圆柱体方式布置，阀塔罩壳也为正方体或圆柱体，与阀塔本体的结构对应即可。
一实施例中，阀塔罩壳上的散热孔设置在检修门板上，在其他实施例中，阀塔罩壳上的散热孔也可以设置在其他结构上。
本申请提供的各个实施例/实施方式在不产生矛盾的情况下可以相互组合。
以上所述仅为本申请的较佳实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
