环境污染与治理一直是社会关注的热点问题,随着城市化进程快速发展,因城市规划与用地的限制,作为重要电力分配场所的配电室越来越多地安置于城市办公区或居民楼区内。配电室内变压器、风机等设备运行时会产生环境噪声污染。同时设备振动会通过地面以及建筑结构向外传播,不仅激发环境振动污染,而且还可能诱发二次结构噪声。面对日益增多的投诉与矛盾,对城市配电室所致噪声振动的产生机理、传播规律以及合理的降噪减振措施进行研究具有十分重要的意义。通过现场测试对配电室噪声振动及其传播特性进行分析,以一10 k V典型配电室为例,设计降噪减振的方案和措施,以期达到噪声振动达标排放,改善居民生活和居住环境的目的。
Environmental pollution and pollution control have always been a hot issue in the society. With the rapid development of urbanization and the restriction of urban planning and land use, more and more distribution rooms, as important power distribution sites, are increasingly placed in urban office buildings or residential buildings Area. Power distribution room transformers, fans and other equipment will produce environmental noise pollution. At the same time, the vibration of the equipment will spread out through the ground and the structure of the building, which not only excites the environmental vibration pollution but also may induce the secondary structural noise. In the face of increasing number of complaints and conflicts, it is of great significance to study the generation mechanism, propagation law and reasonable noise reduction and vibration reduction measures of noise and vibration caused by urban distribution rooms. Through the field test, the noise and vibration of the distribution room and its propagation characteristics are analyzed. Taking a 10 kV typical distribution room as an example, the schemes and measures of noise reduction and vibration reduction are designed so as to reach the standards of noise and vibration emission and improve the life and residence of residents The purpose of the environment.
