Embodiment Construction

[0024] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0025] refer to Figure 1 to Figure 3 , a noise reduction device for a converter transformer, comprising a space sound absorber 7, a ventilation and noise reduction device 9, a sound absorption and sound insulation barrier 3, a first sound absorption and sound insulation connecting plate and a second sound absorbing and sound insulating connecting plate 4. The noise reduction device is installed on the body of the converter transformer 6. The noise reduction device surrounds the top surface and the side of the converter transformer, and forms a whole with the converter transformer 6, and can isolate the noise generated when the converter transformer 6 is running. . When the converter transformer 6 is in operation, the entire converter tra...

Abstract

The invention provides a noise reduction device for a converter transformer. The noise reduction device comprises a space sound absorption body, a ventilation sound elimination device, a sound absorption and isolation device, a first sound absorption and isolation connection plate and a second sound absorption and isolation connection plate. The noise reduction device is simple in structure and good in noise reduction effect.

Description

technical field [0001] The invention is designed for noise control, and in particular relates to a noise reduction device for a converter transformer. Background technique [0002] When the converter transformer is running, due to the large number of harmonics generated by the commutation threshold and the DC bias flowing through the converter coil, the noise of the converter transformer is significantly larger than that of the AC transformer, which is the noise of the converter station. Noise sources that need to be focused on during treatment. [0003] The existing commonly used converter transformer noise control methods are as follows: [0004] The barrier method in front of the converter transformer, this method is to install a sound insulation barrier in front of the converter transformer cooler or between the converter transformer body and the cooler. The top of the plug floats out, and the entire sound insulation barrier needs to be removed when the converter trans...
