[0002] A transformer is a device used to convert an AC voltage of one value into another with the same frequency or several voltages with different values. The iron core vibrates periodically with the change of the excitation frequency, resulting in noise, and the transformer usually cools the radiator through the fan, and the fan and the oil pump vibrate during operation, which also produces a lot of noise, and with the internal parts of the transformer Aging and loss of oil between transformer parts are also one of the reasons for transformer noise

Embodiment Construction
[0025] In order to make the purpose and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the examples. It should be understood that the following words are only used to describe a noise reduction transformer or several specific implementations of the present invention, and do not imply the present invention. The scope of protection specifically claimed by the invention is strictly defined. As used herein, the terms up-down and side-to-side are not limited to their strict geometric definitions, but rather include reasonable and inconsistent tolerances for machining or human error, which are described in detail below. The specific characteristics of a noise reduction transformer:
[0026]Referring to the accompanying drawings, a noise reduction transformer according to an embodiment of the present invention includes a platform 11, and two symmetrical support rods 12 are fixed on the top surface of the platfor...

The invention discloses a noise reduction transformer. The noise reduction transformer comprises a platform, two supporting rods which are in bilateral symmetry are fixedly arranged on the top face of the platform, a sliding plate is arranged between the two supporting rods in a sliding mode, a shell is fixedly arranged on the top face of the sliding plate, a transformation cavity is formed in the shell, and an upper cover plate and a lower cover plate are arranged in the transformation cavity in a sliding mode; an upper transverse iron is fixedly arranged on the bottom face of the upper cover plate, a lower transverse iron is fixedly arranged on the top face of the lower cover plate, three vertical irons which are arranged at equal intervals from left to right are fixedly arranged on the bottom face of the upper transverse iron, a radiator is fixedly arranged on the left side face of the shell, a cooling box is fixedly arranged on the left side face of the shell, and a heat removal box is fixedly arranged in the platform. By installing the four hydraulic shock absorbers, shock absorption of the iron core of the transformer in multiple directions can be achieved, springs are installed in the middle of the iron core of the transformer for buffering, vertical shock of the iron core of the transformer is further reduced, and therefore noise generated by shock of the iron core of the transformer is reduced.
Description
technical field [0001] The invention relates to the technical field of transformers, in particular to a noise reduction transformer. Background technique [0002] A transformer is a device used to convert an AC voltage of one value into another with the same frequency or several voltages with different values. However, under the action of an alternating magnetic field, the iron core inside the transformer will undergo a slight change, that is, magnetostriction. Magnetostriction makes The iron core vibrates periodically with the change of the excitation frequency, resulting in noise, and the transformer usually cools the radiator through the fan, and the fan and the oil pump vibrate during operation, which will also generate a lot of noise, and with the internal parts of the transformer Aging and loss of oil between transformer parts are also one of the reasons for transformer noise. Contents of the invention [0003] The object of the present invention is to provide a noi...
