In oil filled power equipment, if the indication in vernier is inconsistent with the oil level of transformer oil, the problem of false oil level will appear.

这是由于小隔膜外部存在气体，并缺少放气阀，可通过松开法兰螺丝将气放掉，使油位处于正常位置。

This is due to the existence of gas outside the small diaphragm and the lack of vent valve. The gas can be released by loosening the flange screw, so that the oil level is in the normal position.

变压器的隔膜保护因维修工作任务较少、保护效果较好而被广泛使用。

The diaphragm protection of transformer is widely used because of less maintenance tasks and better protection effect.

但在隔膜保护变压器的实际运行中，常出现这类问题：油位原本指在特定油温线上，但是当温度变化显著时，油位会快速上升到游标的顶端，甚至出现溢油现象；如果温度下降幅度大，游标就会下降到底端看不到的位置，甚至会使瓦斯继电器发出轻瓦斯信号。

But in the actual operation of the diaphragm protection transformer, this kind of problem often occurs: the oil level originally refers to the specific oil temperature line, but when the temperature changes significantly, the oil level will quickly rise to the top of the vernier, and even oil spill phenomenon; if the temperature drops greatly, the vernier will drop to the invisible position at the bottom, and even make the gas relay send out light gas signal.
                

出现假油位运行故障的原因有哪些？若变压器等充油电力设备中出现假油位问题时，山东变压器油为您分析此类运行故障的原因包含以下几方面：

What are the causes of false oil level operation fault? If there is a false oil level problem in oil filled power equipment such as transformer, Shandong transformer oil will analyze the causes of such operation faults for you, including the following aspects:

1、进油阀的安装位置不正确，进油的压力串在隔膜下侧，会导致隔膜中的油逐渐上升至喷出。

1. If the installation position of the oil inlet valve is not correct and the pressure string of the oil inlet is under the diaphragm, the oil in the diaphragm will gradually rise to eject.

2、油枕中的油面受到了大气压强作用，同时环境温度变化过大、冷却系统发生故障、负荷较大等因素会导致油的体积变大，占据油枕中小隔膜的空间，气体膨胀导致油枕失去呼吸作用，变压器油会随着游标流出，从而出现压力释放现象。

2. The oil level in the conservator is affected by atmospheric pressure. At the same time, the environmental temperature changes too much, the cooling system fails, the load is large and other factors will cause the oil volume to become larger, occupying the space of the small diaphragm in the conservator. The gas expansion will cause the conservator to lose its breathing function, and the transformer oil will flow out with the vernier, resulting in pressure release.
