Embodiment Construction

[0009] Accompanying drawing is a kind of specific embodiment of the present invention.

[0010] The low-noise amorphous alloy transformer of the present invention comprises a plurality of iron cores 5 connected together, and coils 6 are sheathed on the iron cores. The frame of the transformer body is formed by clips 3 and the iron cores. Plate 1, the transformer body is placed in the oil tank; the iron core is made of the latest amorphous alloy 2605 HB1M material with high magnetic flux saturation density; after the iron core lap is completed, an 8mm thick rubber pad 7 is placed on the bottom to reduce the Noise generated by hysteresis shrinkage; wrap a layer of 1mm thick nitrile rubber skin 4 on the outside of the iron core 5 to hinder the propagation path of noise and reduce noise; place a 20mm thick shock-absorbing rubber pad 8 on the bottom of the fuel tank, and place a 20mm thick shock absorbing rubber pad 8 on the body hanging plate 1. A 10mm rubber pad 2 is placed at th...

Abstract

The invention discloses a low-noise amorphous metal transformer. An iron core is made of an amorphous metal 2605HB1M material with high saturation flux density; after the iron core is lapped, the bottom of the iron core is provided with a rubber pad which is 8mm in thickness to reduce noise generated by magnetic-lag contraction; the outer side of the iron core is coated with a layer of nitrile rubber which is 1mm in thickness to hinder a travel path of the noise and reduce the noise; a shock-reducing rubber pad which is 20mm in thickness is arranged at the bottom of an oil tank, a joint of a transformer body hanger plate and a clamp is provided with a rubber pad which is 10mm in thickness, and the noise generated by vibration of the iron core is reduced. The noise is reduced by changing the material of the iron core and arranging the rubber pads to hinder the travel path of the noise and reduce vibration frequency, so that the noise of the amorphous metal transformer can be controlled to be lower than 45dB and the noise is obviously reduced. The iron core is made of the new amorphous metal 2605HB1M material, the noise is reduced and the energy-saving effect is better.

Description

technical field [0001] The invention belongs to transformers, and relates to a low-noise amorphous alloy transformer. Background technique [0002] At this stage, amorphous alloy transformers have low no-load loss and are very energy-saving. However, due to the large noise (mostly between 50 dB-60 dB), when installed in residential areas, it seriously affects the living environment of residents and restricts this energy saving. Promotion of consumption-reducing amorphous alloy transformers. Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the invention provides a low-noise amorphous alloy transformer with simple structure, energy saving and consumption reduction, and low noise. [0004] The present invention is achieved through the following technical solutions: [0005] The low-noise amorphous alloy transformer of the present invention is characterized in that it includes several iron cores connected together, the...
