Description
技术领域 technical field
本发明涉及通信局站地网距离去偶方法，尤其是涉及强电对通信局站危险影响时通信局站地网距离去偶方法。 The invention relates to a method for decoupling the ground network distance of a communication station, in particular to a method for decoupling the ground network distance of a communication station when strong electricity has a dangerous influence on the communication station.
背景技术 Background technique
随着通信和电力两个重要系统的快速发展，通信局站位于高压输电线及高压变电站附近的情况越来越普遍，当两者距离较近时，高压输电系统会对通信局站中的人和设备产生安全影响。当高压输电系统发生接地故障的情况下，在高压输电系统地网上会产生巨大的瞬间地电位升，并通过大地的阻性耦合在通信局站的地网上而感应出高电位。这个高电位将对通信局站的工作人员和通信设备产生危险影响。以往防止这种危险影响的方法只能采用距离去藕方法，即增加通信局站和高压输电系统的距离来减小高压输电系统对通信局站的危险影响。这种方法主要缺点是限制了通信局站的选址范围，使得很多位置不能建设通信局站。 With the rapid development of the two important systems of communication and electric power, it is more and more common for communication bureaus to be located near high-voltage transmission lines and high-voltage substations. and equipment security. When a ground fault occurs in the high-voltage transmission system, a huge instantaneous ground potential rise will occur on the ground network of the high-voltage transmission system, and a high potential will be induced on the ground network of the communication station through the resistive coupling of the earth. This high potential will have a dangerous effect on the staff and communication equipment of the communication station. In the past, the only way to prevent this dangerous effect is to use the distance decoupling method, that is, to increase the distance between the communication station and the high-voltage transmission system to reduce the dangerous effect of the high-voltage transmission system on the communication station. The main disadvantage of this method is that it limits the site selection range of communication bureaus, making it impossible to build communication bureaus in many locations.
