Oil level monitoring and warning device for oil conservator special for transformer

Abstract

The invention relates to an oil level monitoring and warning device for an oil conservator special for a transformer. The oil level monitoring and warning device is mainly characterized by comprising a light source emitter, a light source receiver, a photovoltaic conversion unit and a warning unit, wherein the light source emitter and the light source receiver are arranged in the oil conservator special for the transformer, the photovoltaic conversion unit is connected with the light source receiver, and the warning unit is connected with the photovoltaic conversion unit; the light source emitter is installed on the inner wall of the oil conservator and located above the oil level in the oil conservator; the light source receiver is installed on the inner wall, opposite to the light source emitter, of the oil conservator and located below the oil level in the oil conservator; the light source emitter irradiates a light beam of an emitting point to the light source receiver on the other side of the oil conservator at a certain angle. The oil level monitoring and warning device is reasonable in design; according to the refraction principle of light on an interface between gas and oil in the transformer, the oil level of the oil conservator in the transformer is reflected; meanwhile, according to the photovoltaic conversion principle, optical signals are converted into electric signals, and then the electric signals are output, so that the warning function is achieved; the oil level monitoring and warning device has the advantages of being safe and reliable in detection, accurate in testing result, easy and convenient to operate, high in anti-interference capacity and the like.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a special oil conservator oil level monitoring and alarming device for transformers. Background technique [0002] Transformer oil is the main insulating material of oil-immersed transformers, and its amount in the transformer determines whether the insulation state of the transformer is good. At present, the oil level detection of the transformer special oil conservator is still limited to the visual detection by the inspectors, and because the oil level cursor often jams, it cannot accurately reflect the real situation of the oil level. Therefore, there is an urgent need for a device that is used to help inspectors intuitively and accurately discover the oil level of the transformer oil conservator and give an alarm in time. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a special oil ...
