摘要
通过对线路变压器组接线方式及其适用场所,灵活性、可靠性及占地面积等方面优缺点以及继电保护要求的分析,明确线路变压器组接线方式是变电站主接线的最简单形式,用在终端变电所并不影响可靠性,不仅适用于用户终端变电所,条件许可时也可用于用户总降压站,采用线路变压器组接线方式时变压器高压侧应采用负荷开关,以减少断路器数量。
This paper states that the wiring method of line-transformer unit is the simplest form of main wiring of substation by analyzing the wiring form and its applicable place,flexibility,reliability and occupied area as well as the requirements for relay protection,which is applicable to the user’s end substation and general voltage dropping station if condition permits.The load switch shall be adopted on the high-voltage side of transformer when using the line-transformer unit wiring method so as to reduce the quantity of circuit breaker.
