介绍了一种Sepam装置在亚运海心沙场馆10 kV母联备自投中的应用方案。通过对控制程序进行合理的逻辑设计,实现了母联互投备自投功能。根据继电保护整定计算原则和场馆实际情况,对整定项目进行整定计算。按照回路原理和功能,进行现场调试、回路试验。装置设计简单,现场便于维护,能够监视外部开入回路,具有通信功能,且动作可靠性高。系统介绍作为亚运会开闭幕式的举办地,对安全可靠的用电要求也是极为严格。海心沙场馆高压系统采用10 kV双回路电源供电,共设8路10 kV电源。每路电
The application scheme of a Sepam device in the 10 kV bus coupler self-transmission at the Asian Games Haixinsha stadium is introduced. Through reasonable logic design of the control program, it achieves the function of mutual coupling and self-casting. According to the setting principle of relay protection and the actual situation of the stadium, the setting project will be set and calculated. According to the circuit principle and function, conduct on-site debugging, loop test. The device is simple in design, easy to maintain in the field, able to monitor the external opening circuit, has the communication function, and has high operation reliability. System Introduction As the venue for the opening and closing ceremonies of the Asian Games, the safe and reliable power requirements are extremely strict. Hai Xin sand venues high-voltage system with 10 kV dual-loop power supply, a total of 8 10 kV power supply. Every electricity
