An important aspect of these automation, is in power system malfunction or abnormal operation state, can automatically respond and handle failure. Such as: the parameters and the determination of position of fault, the fault equipment put into standby equipment removal, etc., relay protection and automation device for power system of these devices called. The socalled relay, refers to the mutual replacement of circuit and continuation. By using the circuit this mutual replacement and continuity and protection measures of power system structure called the relay protection. Relay protection and automation technology is in a science and technology developed rapidly in recent decades. Protection most early, is a reaction line short circuit fault and the current increase in current protection. Usually use the fuse (fuse) is one of the most simple current protection. However, with the development of power system, the fuse has been far can not meet the requirement of power system protection, and the emergence of a relay. With the change of reaction current relay, and the circuit breaker tripping fault removal equipment, plays a role in protection, which formed the socalled relay protection. The relay protection is an important measure to ensure the safe and reliable operation of power system. In the modern power system relay protection device, if no new is good, it is impossible to maintain the normal work of the system. Not only that, development and relay protection device of the relay protection technology to further improve, will effectively promote the development of the electric power system. 陜西鐵路工程職業(yè)技術(shù)學(xué)院畢業(yè)設(shè)計（論文） 3 目錄 1. 牽引變電所一次設(shè)備概述 ....................................................................................................4 電氣化鐵道牽引供電系統(tǒng)概況 ....................................................................................4 牽引變電所的分類 .....................................................................................................5 牽引供電系統(tǒng)向接觸網(wǎng)的供電方式 .............................................................................6 ..........................................................................................................8 電氣主接線 .............................................................................................................. 10 主變壓器 ................................................................................................................. 10 高壓斷路器 ....................................................................................................
