新一代天气雷达站防雷接地体的分析与设计

结合玉林新一代天气雷达站的地理、地质、气象、环境特点,分析了防雷接地的特性。降低接地电阻主要采取降低接地体的接触电阻和散流电阻的方法,增加接地体围面积对接地电阻的减小有利,另外,还要充分考虑复合接地体形状和接地网内屏蔽效应对接地电阻的影响。设计时应充分考虑接地体的特性,控制在地网等效半径的有效长度内,以满足接地电阻的要求。还宜采取不等长技术、施放降阻剂和更换接地极周围土质的降阻措施。

Exploration on ecological regulation of the reservoirs

Reservoir regulation process in the Yangtze River Basin is mainly divided into two types of flood regulation and initiating benefit regulation. The present reservoir management system and operation mode are mainly fro dealing with or coordinating of flood control and benefit initiation as well as benefit distribution among various beneficial functions. From the view point of river eco-system protection, the current regulation mode has two kinds of problems: firstly, most of the reservoir regulation plans do not consider eco-system protection at downstream of dams and needs of environment protection in reservoir areas; secondly, integrated regulation or management of water resources is ignored. It is very necessary to improve reservoir regulation mode, bearing problems faced by regulation of the Three Gorges Reservoir and issues related to cascade development and regulation in Tuojiang and Minjiang River Basins in mind. In accordance with the concept of scientific development, and the philosophy of “ensuring a healthy Yangtze River and promoting the harmony between human and water”, taking flood control, benefit initiation and eco-system as a whole, this paper put forward the basic consideration to improve reservoir regulation as follows: on the basis of requirements of eco-system protection at downstream of dams and needs of environment protection in reservoir areas, we should bring the functions of reservoir such as flood control and benefit initiation into full play, control the negative influence to the eco-system at downstream of dams and the environment in reservoir areas in an endurable scope, and restore the eco-system and the environment step by step. This paper put forward the relevant regulation process aiming at the idiographic problems such as protection of eco-system at downstream of dams and environment in reservoir areas, protection of aquatic wildlife species and fish species, regulation of sediment and protection of wetland.
