Description

换流阀晶闸管组件散热器 技术领域
本发明属于直流输电换流阀领域，特别涉及一种换流阀晶闸管组件散热器。
背景技术
直流换流阀是直流输电的核心设备，换流阀通常由多个组件组成，换流阀组件包括晶闸管组件、阳极电抗器等，晶闸管组件内还包括晶闸管、散热器、阻尼电阻、阻尼电容以及与其配套的冷却系统，换流阀结构复杂、零件繁多，在运行过程中会因各种原因发生故障，故障发生后需及时进行检修以尽快恢复换流阀的正常运行，因此在换流阀的设计过程中需要在各环节考虑设备检修的便利性。
目前晶闸管组件内阻尼电阻主要有两种形式，第一种：阻尼电阻为水电阻，阻尼电阻与冷却水直接接触，独立散热，与晶闸管散热器及其冷却水管互不干涉，冷却系统正常运行时，阻尼电阻能够得到良好的散热，但若阻尼电阻异常需要检修时，需要将换流阀内的冷却水全部排出后才能开始检修工作，检修难度大、耗时长；第二种：阻尼电阻为棒电阻，多个棒电阻布置于晶闸管散热器内预先设置的通孔中，阻尼电阻通过晶闸管散热器间接散热，减少了晶闸管组件内的接头，专利CN201937444U公开了一种晶闸管换流阀模块，其中提到棒电阻及冷却水管的连接方式，但部分棒电阻与晶闸管散热器的冷却水管存在干涉的现象，检修棒电阻时仍需将换流阀内的冷却水全部排出后才能拆卸冷却水管，检修困难，耗时长。
