Description

Technical Field

[0001] The utility model relates to the technical field of transformer installation, in particular to an installation fixture of an EI type transformer and an application system thereof. Background Art

[0002] Transformers have been widely used in household appliances and other electronic equipment with high technical requirements. Their main function is to serve as power transformers and isolation transformers, and they are used in computers, medical equipment, telecommunications, instruments, lighting and other fields.

[0003] The EI type transformer is a type of transformer. Its core is composed of "E" type sheets and "I" type sheets superimposed on each other. It is called the EI transformer according to its shape. The EI type transformer has a relatively simple structure, is easy to process and manufacture, is convenient to wind, has low cost, and has good anti-saturation performance, making it one of the most widely used transformers.

[0004] During the installation of the EI type transformer, the prior art generally uses a fixing device to first press and fix the "E" type sheet and the "I" type sheet in the transformer, and then welds the pressed and fixed "E" type sheet and "I" type sheet to obtain the iron core, and then welds the iron core to the mounting plate, thereby completing the installation of the EI type transformer and ensuring the fixation and ventilation and heat dissipation effect of the EI type transformer after installation. However, the traditional fixing device does not have the function of placing and fixing the mounting plate, resulting in the need to weld the iron core to the mounting plate without fixing after the iron core is welded, which not only easily affects the accuracy of the welding between the iron core and the mounting plate, and then affects the firmness of the installation, but also easily affects the appearance of the EI type transformer.
