The Direction And Investigation Of GIS Synthesis Automatization Transformer Substation Relay Protection Construction

This thesis links with the basic knowledge of electric power system, emphasizing to introduce a series of problems and solutions in the GIS synthesis automatization transformer substation relay protection construction. The thesis also mention about the differences between GIS transformer substation and general transformer substation via analyzing and summing up the important equipments relay protection construction, which are Current Transformer, Voltage Transformer, Breaker, according to the statistics from the experiment result. Meanwhile, The thesis research and discuss the typical problems and the error examples, which is only happening in construction for GIS transformer substation. Current Transformer mainly probe into the approach of linking wire and a variety of experiments, Voltage Transformer embodies the differences between GIS equipment and General equipment through a serious error, there is a problem we should pay attention to, breaker, switch is analyzed its controlling circuit and locked circuit. The thesis has been coming in being the working reference for GIS transformer substation relay protection construction by summing up the practice working experience. The reference arises from summary, representing the correct construction flow, avoiding the re-construction owning to the mistake or omission. Statistics as a detail reference, on the other hand, it provides the information for the correct construction. The objective of the thesis focus on Catholicity and Practice, it is rather meaningful for GIS transformer substation relay protection construction. As well as, it can be used for electric power system and relative basic knowledge education.
