Background
In recent years, with the progress of transformer design and manufacturing process, the finned radiator hanging body of the transformer has become the mainstream form of the appearance of the transformer in recent years. The sheet hanging body can effectively save main materials of the transformer and reduce the use amount of steel plates and transformer oil, so that the sheet hanging body is widely applied to natural oil circulation self-cooling and air-cooling transformers. However, the bulk-hung tablet body still has certain limitations, which are mainly embodied in the following two aspects:
1. the number of tablets and powder. When the capacity of the transformer is large or the transformer is in a self-cooling mode, the number of the scattered sheets is large and exceeds the shell range of the transformer, and an oil collecting pipe mode is needed at the moment;
2. transformer tank form. Oil-immersed transformers can be divided into barrel type and bell type from the form of an oil tank shell. The barrel type oil tank is limited by the tank edge, and the heat dissipation center cannot be raised as much as possible, so that the heat dissipation effect is poor compared with a bell-type oil tank.
Therefore, a new structural form is needed for the transformer of the barrel-type oil tank, and the installation space of the plate radiator is increased under the condition that the radiating effect meets the requirement.
