文档介绍：农村35kV无人值守变电所设计
摘要
随着电网容量的增加,综合自动化水平的需求,无人值守变电所的建设已经是当今电力事业发展的潮流。
本变电所位于乡镇边缘,公路交通方便,主要为生活用电和农业用电所设计的,以三类负荷为主。35kV侧采用一回进线、主变压器采用一台S6—3150/35型双绕组变压器;主变压器35kV侧采用SW3-35型断路器配合GW5-GD600型隔离开关作为保护和控制;10kV侧采用单母线接线;出线4回;10kV主进线采用LN2-10型SF6断路器、出线采用断路器与保护控制器配合作为控制和保护。10kV侧电容器选用集合式BFM型并联电容器;电流互感器和电压互感器均选用干式互感器;35kV,10kV侧避雷器全部选用HY5W5型阀型避雷器。二次设备采用综合自动化装置LFP-900系列。

Abstract
With the increase of the capacity of the electric ting , improvement of the voltage grade, the demand for prehensive automation level, the construction of the transformer substation with no guard is nowadays trend of development of electric cause.
This transformer substation lies in the edge of villages and towns, the munication is convenient, mainly design in order to live with the electricity with electricity and agriculture, take three kinds of load as the core. 35kV side adopt one enter line , main voltage transformer adopt one capacity S6- 3150/35 type to have , transfer and pigeonhole the voltage transformer year; The main voltage transformer 35kV side adopts the circuit breaker of the Model SW3-35 to cooperate with the GW5-GD600 type to isolate the switch as protecting and controlling; 10kV side adopt single bus bar simple and easy to segment wiring; Qualify for the next round petitions 4 times; 10kV enter line adopt Model LN2-10 vacuum circuit breaker , qualify for the next round petitions , adopt circuit breaker with protect controller cooperate as controlling and protecting mainly. 10kV side condenser selects the set type BFM type for use and connects the condenser in parallel; The mutual inductor of the electric current and voltage mutual inductor select the doing type mutual inductor for use ; 35kV, all 10kV arresters select the valve type arrester of Model HY5W5 for use. Apparatus two times adopts the device LFP-900 series prehensive automation.
