The invention discloses a converter transformer on-line monitoring device which comprises a fixed-point sampler and a monitoring host arranged on one side of a converter transformer. The fixed-point sampler is composed of an outer protective sleeve rod arranged on an upper sealing plate of the converter transformer in a penetrating mode, a fixed-point isolation assembly for separating different layers of transformer oil and an inner sampling pipe arranged in the outer protective sleeve rod in a sliding mode, and a depth adjusting part is arranged at the top of the fixed-point sampler; oil samples of different oil layers can be collected through the fixed-point sampler, fixed-point detection and multi-point detection are achieved, the detection accuracy is higher, the inner sampling pipe does not collide with devices in the converter transformer during collection, the fixed-point isolation assembly can separate oil samples of other layers, and when sampling is not carried out, the oil samples in the other layers can be separated by the fixed-point isolation assembly. The mobility of transformer oil in the converter transformer can be improved through movement of the fixed-point isolation assembly, and the heat dissipation effect can be improved; the power system can control the depth adjusting part and the heat dissipation part at the same time and can also independently control the heat dissipation part, flexibility is high, energy is saved, and more environmental friendliness is achieved.
本发明公开了换流变压器在线监测装置,包括定点采样器以及设于换流变压器一侧的监测主机,所述定点采样器由贯穿设置于换流变压器上封板的外保护套杆、分隔不同层变压器油的定点隔离组件以及滑动设于外保护套杆内的内采样管组成,定点采样器顶部设有深度调节部;本发明通过定点采样器能采集到不同油层的油样,实现定点检测和多点检测,使检测的准确性更高,采集时内采样管不会碰撞到换流变压器内部的器件,定点隔离组件不仅能隔开其他层的油样,且不进行采样时,定点隔离组件的移动可以提高换流变压器内部变压器油的流动性,有利于提高散热效果;动力系统能同时控制深度调节部和散热部,也能单独控制散热部,灵活性高,且节省能源,更加环保。
