Abstract

The invention discloses a damping and noise-reducing device for a dry-type transformer. The damping and noise-reducing device comprises a visible noise-reducing shell, a plurality of vibration isolation pieces and a noise elimination and heat dissipation mechanism. The noise elimination and heat dissipation mechanism comprises an air inlet noise reduction device and an exhaust noise reduction device. The vibration isolation piece and the noise elimination and heat dissipation mechanism are both arranged in the visible noise reduction shell. According to the visual noise reduction shell, noisegenerated by the transformer can be isolated, and meanwhile people can conveniently observe the running condition of the transformer from the outside. The vibration isolation part is used for processing resonance generated by the transformer to realize a vibration isolation function. Through cooperation of the air inlet noise reduction device and the air outlet noise reduction device, hot air generated by the transformer can be dredged in time, and the fault probability of the transformer is greatly reduced.

Description

technical field [0001] The invention relates to the field of shock-absorbing and noise-reducing equipment, and more specifically, relates to a dry-type transformer shock-reducing and noise-reducing device. Background technique [0002] With the progress and development of society, the power consumption continues to increase, and the load demand of residents increases day by day. The power supply department installs transformers in each residential area. Since the transformer will generate a certain range of noise during operation, noise complaints and disputes occur from time to time. At present, in indoor distribution stations, the noise level of 10kV dry-type transformers reaches 60-80dB. The main source of noise is the electromagnetic noise generated during the operation of transformers, and the low-frequency noise has a greater impact on residents in residential areas. The noise in the low frequency band is different from the noise in the high frequency band. The high f...
