Embodiment Construction
[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0030] see Figure 1-Figure 4, an oil-immersed transformer for a power distribution system, comprising an outer box body 1, a fixed platform 2 is fixedly installed on both sides of the inner cavity of the outer box body 1, a transformer device 3 is fixedly installed on the top of the fixed platform 2, and the outer box body 1 A circular through-hole I is opened at the center of the top, an exhaust device 4 is fixedly installed on the top of the circular throug...

The invention relates to the technical field of power supply transformation, and discloses an oil-immersed transformer for a power distribution system. A circular through hole I is formed in the center of the top of an outer box body, an exhaust device is fixedly mounted at the top of the circular through hole I, an air guide pipe is fixedly mounted on the outer surface of the exhaust device, and the air guide pipe communicates with an inner cavity of the exhaust device; heat dissipation devices are fixedly installed on the two sides of the outer surface of the outer box body. When the temperature in the outer box body is too high to cause high-pressure oil gas, the oil gas enters the exhaust pipe through a circular through hole I in the center of the top of the outer box body, so that the stroke ring is jacked up, and due to the fact that a single through hole is formed in the center of the single-pass plate, the oil gas cannot penetrate through the single-pass plate through the single through hole, and the stroke ring is jacked up. And the oil gas pressure jacks the one-way plate to the position above the gas guide hole, so that the oil gas enters the gas storage cavity through the gas guide pipe and is cooled under the action of the cooling fan, the problem that high-temperature oil gas is directly discharged by traditional equipment to cause deflagration and tempering is solved, and the safety performance of the device is improved.
Description
technical field [0001] The invention relates to the technical field of power supply transformation, in particular to an oil-immersed transformer for a power distribution system. Background technique [0002] Transformer is a very common type of power equipment. Existing transformers can be divided into two types, one is dry-type transformer, and the other is oil-immersed transformer. Insulating oil is used for insulation, so that it has good heat dissipation performance and a high transformation range. Compared with dry-type transformers, the cost of oil-immersed transformers is also lower, and it is currently the most widely used type. transformer. [0003] Although the existing oil-immersed transformer has many advantages, there are still some limitations in the actual use process. Because the current and voltage inside the transformer are at a relatively high level, the heat dissipated is very high, and The outer insulating layer will gradually corrode, and the arc gene...
