变压器压力释放阀在线试验初探

Initial investigation of on-line test of transformer pressure relief valve

变压器压力释放阀在运行中存在一定的隐患,目前还没有现场校验的手段,为及时发现和消除隐患,介绍了一种在线试验方法的试验步骤及注意事项。但在线试验只能进行定性检查,不能取代压力释放阀的校验工作。

In the operation of transformer pressure relief valve,there is a certain hidden trouble. There is no in-situ inspection which can discover and eliminate the hidden trouble in time. An online test is introduced,together with the test method,procedures and matters needing attention. But the online test can only be carried out as qualitative check. It cannot replace the verification of pressure relief valve.
