某用户 35kV 变电所及其综合自动化系统设计摘要 : 35kV 变电所综合自动化系统主要为无人值班形式，其设计应服从电网调度自动化的总体设计，其配置、功能包括设备的布置应满足电网安全、优质、经济运行以及信息分层传输、资源共享的原则。因此,本次设计我们将以此作为设计指导原则展开设计工作。整个设计过程包括总降压变电所电气设计、10kV 中性点接地设计与所用电设计、微机保护及综合自动化系统设计。我们将从各种相关方案中比较确定出最佳设计方案。其中总降压变电所采用内桥式的接线方式，10kV 中性点采用经过小电阻接地，所用电采用接地变压器兼所用变压器的形式。本设计提供一整套可用于指导施工的工程设计图纸。关键词 ：变电所，综合自动化，微机保护，中性点接地Design on Customer 35kV Substation And The Synthesize Automation System Abstract: The complex automatic system nobody's form on duty 35kV transformer substation mainly it designs overall design that should obey automation of dispatching of power netwoks , it dispose, including equipment to decorate and should meet electric wire netting safe, high-quality, economical operation and information strata transmit, principle of resource-sharing function. Design we regard this as and design guideline launch the design work this time. Whole design process including electric to design to step down transformer substation always, 10 kV neutral some earth design with power consuming design, computer protect and complex automatic system design. We will relatively determine the best plan of design from various kinds of relevant schemes . Step down transformer substation wiring way of bridge type in adopting always among them, 10 kV neutral to adopt through disappear arc coil earth a bit, adopt the earth voltage transformer and concurrently form of the voltage transformers used with the electricity. Design and offer a whole set of can with use for project design drawing constructed to...
