Opening and changing all-in-one machine

Abstract

The invention discloses an opening and changing all-in-one machine. The machine comprises a shell, an iron core and a high-voltage switch, the iron core is arranged in the shell, the high-voltage switch is directly connected with the iron core in the shell, the other binding post of the high-voltage switch penetrates through the wall surface of the shell to serve as an external connection position, and the shell is filled with a cooling working medium. Cooling fins are arranged on the outer surface of the shell. The shell comprises a main shell, shunting pipes, converging pipes and heat dissipation pipes, the number of the shunting pipes is the same as that of the high-voltage switches, the bottom ends of the shunting pipes are connected to the upper end of the main shell, the upper ends of the shunting pipes converge and are concentrated to the converging pipes, the end portions of the converging pipes are bent downwards and connected with the heat dissipation pipes, the heat dissipation pipes are attached to the outer surface of the main shell, a return opening is formed at the bottom end of each heat dissipation pipe, the return openings are inserted into one side of the bottom of the main shell, the opening and changing all-in-one machine further comprises a circulating pump, the circulating pump is arranged at the bottom in the main shell, an inlet of the circulating pump is connected with the return opening, an outlet of the circulating pump pumps a cooling working medium to the bottom in the main shell, and the roots, connected with the shell, of the cooling fins penetrate through the heat dissipation pipes to be inserted into the side face of the main shell.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an all-in-one switching machine. Background technique [0002] Transformers and high-voltage switches are commonly used devices in power systems. In the prior art, both are produced separately and then installed together on site. The process of on-site installation and commissioning is significantly complicated. Moreover, the connection reliability between high-voltage switches and transformers is improved. No further improvement. [0003] The transformer will emit a lot of heat during operation, and there will be partial arcs when the high-voltage switch performs on-off actions, which need to be reliably eliminated and limited. How to further improve the heat dissipation performance of the device on the basis of the structure combining the high-voltage switch and the transformer is also a problem that needs to be further considered and solved in the prior art.
