SBH15-M sealed amorphous alloy power transformer

Abstract

The invention discloses an SBH15-M sealed amorphous alloy power transformer, and belongs to the field of power transformers. The SBH15-M sealed amorphous alloy power transformer comprises a transformer body, wherein the transformer body is internally provided with an oil tank; an oil column is mounted at the left upper end of the transformer body; the oil column is communicated with the oil tank;a self-vibration funnel is inserted in the oil column; the self-vibration funnel comprises a large-mouth oil storage bucket and a narrow-mouth oil leakage pipe; vibration can be generated during an oil complementation operation through a vibrating four-way ball, so as to enable transformer oil to enter the oil tank rapidly, thereby greatly improving the oil complementation efficiency; due to the using of the vibrating four-way ball, the operators do not need to manually swing the oil complementation funnel during the oil complementation, so that the oil complementation safety is improved and the sudden sprinkling probability of the transformer oil is reduced; and through the using of a color checking and sampling mechanism, oil complementation and sampling detection are synthesized into aone-step operation, so that the frequency of opening the oil column is decreased and the workload of the operators can be reduced.

Description

technical field [0001] The invention relates to the field of power transformers, in particular to a SBH15-M sealed amorphous alloy power transformer. Background technique [0002] A power transformer is a static electrical device that is used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. When the primary winding is supplied with alternating current, alternating magnetic flux is generated, and the alternating magnetic flux induces an alternating electromotive force in the secondary winding through the magnetic conduction of the iron core. The level of the secondary induced electromotive force is related to the number of turns of the primary and secondary windings, that is, the voltage is proportional to the number of turns. The main function is to transmit electric energy, therefore, the rated capacity is its main parameter. Rated capacity is a customary value for expressing power. It...

Problems solved by technology

[0003] When the existing sealed transformer replenishes the oil tank, it generally replenishes the oil tank through the ordinary funnel, but when the ordinary funnel is used for oil replenishment, the transformer oil is easily blocked in the funnel due to the effect of the air flow. Affect the oil replenishment efficiency. When this happens, the oil replenisher needs to free one hand to manually shake the funnel to speed up the transformer oil entering the oil tank. In this case, the operator only holds the oil pot carrying the transformer oil with one hand , so it is very easy to accidentally drop the oil pot and spill the transformer oil, resulting in a waste of resources. The transformer oil in the transformer needs to be checked regularly, but it is also for the operation of the oil tank, and the sampling test and oil replenishment are carried out separately. Step-by-step operation increases the workload, and opening the oil column multiple times at the same time will cause the transformer oil in the oil tank to be easily oxidized and deteriorated
