摘要
在介绍500 kV变电站站用电系统的基础上,通过分析两种常用站用电系统备自投方案及各自的优缺点,阐明500 kV东坡站所采用方案的经济性、简易性。通过比较两种常用备自投装置——微机型备自投装置和双电源自动切换装置,阐明采用双电源自动切换装置的可靠性、简便性。站用电系统投产前,按照相关验收规范,对双电源自动切换装置进行调试验收,确认双电源自动切换装置是合格的、可靠的。投产后,双电源自动切换装置进行数次正确、可靠的自动切换,运行状态良好。
On the base of introduction of Station service system of 500 kV transformer substation,the paper illuminates the economical and easiness of scheme adopted by 500 kV Dongpo transformer substation by means of analyzing the advantages and disadvantages of two station service system automatic switching schemes. By comparing the two kinds of reserve power source automatic connection device microprocessor automatic switching device and double power automatic transfer switching equipment,the paper illuminates the reliability and simplicity of double power automatic transfer switching equipment. In accordance with the relevant acceptance specification,testing and checking the double power automatic transfer switching equipment are needed to confirm the equipment is qualified and reliable before the using of Station service system. After the production,the double power automatic transfer switching equipment can execute automatic switch correctly and reliably for several times and has a good running state.
