Transformer structure capable of rapidly replacing sleeve and used in high-seismic-intensity areas

Abstract

The invention relates to a transformer structure capable of rapidly replacing a sleeve and used in high-seismic-intensity areas, and belongs to the manufacturing technical field of a transformer. According to the technical scheme, a high-voltage sleeve (4) is arranged on a high-voltage hoisting seat (6); a high-voltage lead (7) is arranged in the high-voltage hoisting seat (6); a high-voltage hoisting seat heat dissipation apparatus (5) is arranged on the exterior of the high-voltage hoisting seat; and a transformer in a transformer oil tank (10) and a winding (1) connected with an external high-voltage side sleeve are connected with the high-voltage lead (7) and the high-voltage sleeve (4) through a transformer hoisting seat and an oil sleeve (9) for dividing the oil tank. The transformer structure has the beneficial effects as follows: by adoption of the electric power transformer with the structure, when the high-voltage sleeve is damaged, the high-voltage sleeve can be replaced rapidly; only the oil in the high-voltage hoisting seat, instead of the oil in the overall transformer, is processed, so that the power supply recovery time is greatly shortened; and therefore, the transformer structure is of great significance to the power supply recovery of the overall power grid.

Description

technical field [0001] The invention relates to a transformer structure for rapidly replacing bushings used in areas with high seismic intensity, and belongs to the technical field of transformer manufacturing. Background technique [0002] Due to the unbalanced energy distribution and power demand in China, it is necessary for my country to establish a high-voltage long-distance transmission system. The transformer equipment used for raising and lowering the voltage level plays a vital role in the entire system, so it is necessary to ensure the power transformer in the entire system. Reliable operation is of great importance. In my country's high-voltage long-distance power transmission system, sometimes the power transmission and transformation system must pass through areas with frequent high-intensity earthquakes. At present, my country has done a lot of research on the seismic resistance of power systems, but due to the material characteristics of the high-voltage end b...

Problems solved by technology

At present, my country has done a lot of research on the seismic resistance of power systems, but due to the material characteristics of the high-voltage end bushings of UHV transformers, the structure adopted in the background technology cannot fully guarantee that the high-voltage bushings of transformers can be intact under high-intensity earthquakes. , if a high-intensity earthquake occurs and the high-voltage end bushing of the UHV transformer is damaged, it is necessary to replace the high-voltage bushing and restore power supply in a short time after the earthquake, otherwise it may have an adverse effect on post-earthquake rescue

In the existing technology, after the high-voltage bushing is damaged, the oil inside the entire transformer is polluted. After replacing the new bushing, it is necessary to perform thermal oil circulation and filter treatment on the oil inside the transformer, which is very time-consuming
