一种换流变呼吸器紧固专用工具的研制

Development of a Special Fastening Tool for Converter Transformer Respirator

换流变压器是高压直流输电工程中重要的组成部分,为换流阀提供整流电源。换流变压器发生故障可导致换流阀闭锁、停电等一系列严重事故。换流变呼吸器能够过滤空气中的水汽等其他杂质,起到变压器绝缘油吸湿作用,以保证内部的绝缘强度和稳定性,因此换流变呼吸器的检修维护较为重要。设计一种便携式换流变呼吸器紧固专用工具,适用于形状特殊的蝶形螺母,不损坏呼吸器本体,简化作业难度,提高检修效率。

Converter transformer is an important part of high Voltage DC transmission project,providing rectifier power for converter valve.The converter transformer failure will lead to a series of accidents such as converter valve locking,and power failure,etc.The converter transformer respirator can filter water vapor and other impurities in the air,achieve the moisture absorption of transformer insulation oil,and ensure the internal insulation strength and stability.Therefore,the maintenance of converter transformer respirator is more important.Through the design of a special fastening tool for portable converter transformer respirator,it is suitable for butterfly nut with special shape,without damaging the respirator body,which simplifies simplifying the operation difficulty and improves the maintenance efficiency.
