Problems solved by technology
Learning through theoretical knowledge is too abstract, and it is difficult to give trainees specific and intuitive cognition and feelings
Through the study of actual fault cases, first, the chance is too large, and only what kind of faults actually occurred can be used as learning materials; Most of them are of the same type, and cannot accommodate all types of system failures
[0004] 2. The traditional system fault analysis and processing training is not real-time, and it often pushes back the development process of the entire fault event b

The invention discloses a fault demonstration platform of power supply and distribution system. The fault demonstration platform is composed of a relay protection fault demonstration platform and a system voltage fault demonstration platform. A panel of a casing of the relay protection fault demonstration platform is provided with an integrated relay protection module REF543, an integrated relay protection module 7SJ6825, voltage and current terminals, quick-breaker protection, over-current protection, zero-sequence protection and general protection outlet connecting sheets, a micro-break switch, and quick-break, over-current, zero-sequence and general fault tripping indicating lamps; and the system voltage fault demonstration platform comprises a three-phase isolation transformer, a Y/delta-11 transformer, a Y/Y-0 transformer and a Y/Y single-phase transformer. A fault demonstration system can be expanded and upgraded.
Description
technical field [0001] The invention relates to the field of analysis and processing of faults in power systems, and more specifically relates to a fault demonstration platform for power supply and distribution systems. Background technique [0002] The analysis and treatment of power system faults are the focus and difficulty in the operation and maintenance of power supply and distribution networks. The ability to analyze and deal with power system faults is also an essential ability for power system operation and maintenance technicians. In the previous power system knowledge and skills training, the training on system failure analysis and handling has the following shortcomings: [0003] 1. Training in this area can only be based on theoretical knowledge and actual failure cases. Learning through theoretical knowledge is too abstract, and it is difficult to give trainees specific and intuitive cognition and feelings. Through the study of actual fault cases, first, the...
