In Force system environmental pollution complaint event, more than 60% is presented for the complaint of transformer substation in city problem of noise pollution, and such event
Letters and calls scale is increasing, complains mode increasingly sharp, the situation that aggressive behavior grows in intensity；Guangdong Zhong Shan 110kV play gulf and become
During power plant construction, due to worrying sound pollution, the too drastic resident in part repeatedly takes the aggressive behaviors such as drawing banner, rally, parade
" right-safeguarding " is carried out, though Jing all departments dredge, explain that resident is still unsatisfied with repeatedly, or even assemble a crowd to contain traffic main artery, engineering is caused
Shelve nearly 10 years；It is nearer apart from residential block due to it during Shantou, Guangdong 220kV puts into operation at wide emerging station, resident living is disturbed, receive
A lot of noises disturb residents complaint event, and many residents even repeatedly complain to the higher authorities about an injustice and request fair settlement relevant departments, cause very bad social effectiveness.Thus
It can be seen that, transformer substation in city problem of noise pollution very likely becomes the inducement of social event, serious harm social stability.
Transformer substation in city is mainly indoor substation, sound pollution process in sound-absorbing process based on, mainly by
Each metope installs the sound-absorbing material with high acoustic absorption coefficient, such as centrifugally glass-wool or rock wool additional in transformer room, so as to reach
Reduce the purpose of indoor noise.However, the acoustical technology that at present substation adopts substantially reduces electrical equipment or factory circle
The L of environmentA, have ignored the low frequency characteristic of transformer noise.
In sum, more convenient, efficient absorbing sound and lowering noise device is further developed, effective control indoor transformer is made an uproar
Sound pollution, is those skilled in the art's technical problem urgently to be resolved hurrily.
