A sbh15-m sealed amorphous alloy power transformer

Abstract

The invention discloses a SBH15‑M sealed amorphous alloy power transformer, which belongs to the field of power transformers. A SBH15‑M sealed amorphous alloy power transformer includes a transformer body, an oil tank is installed at the inner end of the transformer body, and the upper left of the transformer body An oil column is installed at the end, and the oil column communicates with the oil tank. A self-vibrating funnel is inserted in the oil column. The self-vibrating funnel includes a wide-mouth oil storage bucket and a thin-mouth oil leakage pipe, which can be used for oil replenishment by vibrating the four-way ball. Vibration is generated, thereby accelerating the transformer oil into the oil tank, which greatly improves the oil replenishment efficiency. At the same time, due to the use of the vibrating four-way ball, the operator does not need to manually shake the oil replenishment funnel during oil replenishment, thereby improving the oil replenishment efficiency. Safety, reducing the chance of accidental spillage of transformer oil. At the same time, the use of color inspection and sampling mechanism combines oil replenishment and sampling inspection into one operation, which can not only reduce the number of oil column openings, but also reduce the workload of operators.

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
