Technical Field

[0001] The invention relates to the technical field of transformers, and in particular to an integrated flameproof dry-type transformer. Background Art

[0002] Flameproof dry-type transformers are mostly used in mines with methane mixed gas and coal dust and explosion hazards. As the main field equipment of the automated centralized control system, the country continues to strengthen the construction of coal mine production automation in order to realize the automation, intelligence and informatization of coal mine production as soon as possible. At present, most of the mine flameproof dry-type transformers on the market cannot be well explosion-proof and cannot effectively remove the explosive gas and coal powder inside the transformer. The explosive gas and coal powder inside the transformer are prone to explosion, and the excessive temperature of the transformer is also prone to explosion. Therefore, we proposed an integrated flameproof dry-type transformer. Summary of the invention

The serpentine cooling pipe can be equipped with a longer pipeline within the limited space of the shell to achieve a better cooling effect. At the same time, impurities such as coal powder inside the shell are injected into the drainage hole, enter the cooling pipe, and finally enter the pipeline of the explosion-proof mechanism outside the shell, thereby reducing the content of dust such as coal powder inside the shell, and further avoiding explosion.

[0004] Furthermore, a vertical partition is fixedly connected to the surface of the cooling pipe, and the surface of the vertical partition is fixedly connected to the inner side of the shell, horizontal partitions are symmetrically arranged on both sides of the vertical partition, and a number of horizontal partitions are arranged in the gaps of the cooling pipes, and the sides of the symmetrically arranged horizontal partitions close to each other are fixedly connected to the surface of the vertical partition, and the side of the horizontal partition away from the vertical partition is fixedly connected to the inner side of the shell, and the horizontal partitions and the vertical partitions divide the shell into several parts for placing multiple transformer bodies to form a transformer integration.
