Abstract

The invention provides a dry-type electric transformer, including an upper platen, a lower platen, support columns, and a transformer main body. The transformer main body comprises an iron core. The iron core is coiled with a high-voltage winding and a low-voltage winding. The outer sides of the high-voltage winding and a low-voltage winding are provided with insulating cylinders. The middle partof the upper platen is provided with a main terminal. The main terminal is electrically connected with the transformer main body. The support columns are arranged on two sides of the upper platen andthe lower platen. One side of the support column is provided with a cooling fan. The bottom of the lower platen is provided with a damping device. Adjustable bottom feet are arranged under the dampingdevice. The adjustable bottom foot comprises a fixing portion fixed on the lower platen. The fixing portion is connected with an adjusting portion by threads. The bottom end of the adjusting portionis provided with a non-slip mat. The upper part of the upper platen is provided with a lightning arrester. The dry-type electric transformer is advantaged by simple and rational structure, good seismic stability, good heat dissipation, and convenient overhaul.

Description

Technical field [0001] The invention belongs to the technical field of power equipment, and specifically relates to a dry-type power transformer. Background technique [0002] With the continuous improvement of the power supply requirements of the urban power grid and the advancement of transformer technology, the use of dry-type transformers in my country has become quite common. The role of the transformer is multi-faceted, not only can increase the voltage to send electrical energy to the electricity consumption area, but also reduce the voltage to use voltage at all levels to meet the needs of electricity. Generally, transformers are widely used in local lighting, high-rise buildings, airports, and terminal CNC machinery and equipment. In just a few years, dry-type transformer technology has developed rapidly. However, the existing transformer installation process is complicated, its own weight is heavy, time-consuming and labor-consuming, and it is inconvenient to transport...
