Embodiment Construction

[0030] In order to make the above-mentioned features and advantages of the present invention more comprehensible, exemplary embodiments are exemplified below and described in detail in conjunction with the accompanying drawings.

[0031] Considering that the magnetostriction coefficient of the amorphous alloy is relatively high, the vibration of the amorphous iron core caused by magnetostriction is relatively small, the vibration magnitude is relatively large, and the corresponding noise is also relatively large. In order to reduce noise, the present invention arranges sound-insulating felts on both the inner surface and the outer surface of the amorphous alloy iron core to effectively isolate the propagation path of noise and significantly reduce the noise of the amorphous alloy iron core.

[0032] For details, please refer to figure 1 , which is a schematic structural view of an amorphous alloy transformer core provided by an embodiment of the present invention. As shown in...

Abstract

The invention discloses a low-noise amorphous alloy transformer iron core which comprises an inner side wrapping sheet, an outer side wrapping sheet, an amorphous alloy core and deadening felts. The amorphous alloy core is arranged between the inner side wrapping sheet and the outer side wrapping sheet, and the deadening felts are arranged on non-touch surfaces of the inner side wrapping sheet, the outer side wrapping sheet and the amorphous alloy core. The deadening felts are arranged on the inner side surface and the outer side surface of the amorphous alloy transformer iron core, so that noise transmission routes of the amorphous alloy iron core can be effectively isolated, and the low-noise amorphous alloy transformer iron core is simple in process, convenient to operate, low in cost and remarkable in noise reduction effect.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a low-noise amorphous alloy transformer core. Background technique [0002] A transformer is a device that uses the principle of electromagnetic induction to transmit electrical energy. A simple single-phase transformer consists of two conductors and an iron core. When an indeterminate current (such as alternating current) passes through one of the conductors, a changing magnetic field will be generated. According to the principle of electromagnetic induction, the changing magnetic field will cause the second conductor to generate a potential difference; if the second conductor is part of a closed circuit, the closed circuit generates a current and energy is transferred. Since the magnetic field generated by the coil is much larger than that of a straight wire, the conductor is often composed of a coil wound by a wire (such as a copper wire), and the two conductors are call...
