The invention discloses an analog simulation test bench for arc suppression coil complete equipment, which comprises a case and at least one set of arc suppression coil complete equipment, wherein thearc suppression coil complete equipment is arranged on the case; and the case is provided with a standard data interface. The beneficial effects lie in that an analog simulation experiment is accomplished by adopting a simple analog power supply system and simulated arc suppression coil complete equipment; all power supply operating modes in the analog power supply system and various states during a single-phase grounding fault can be simulated by using the analog simulation test bench, and the implementation of various functional experiments of the arc suppression complete equipment can be accomplished; the assembly, transport and maintenance are facilitated by adopting segmented and split design structure of the complete set of the test bench; and the functions of automatic measurement,automatic gear shifting control, automatic compensation set by various compensation states, system grounding line selection, automatic fault tripping and automatic bus coupler recognition of the arcsuppression coil complete equipment can be verified by using the arc suppression coil complete equipment. The analog simulation test bench perfectly simulates the characteristics of an on-site power supply system.
Description
technical field [0001] The invention relates to the field of electric power automation, in particular to a simulation test bench for a complete set of arc suppression coils. Background technique [0002] For power systems with different voltage levels, the neutral point grounding methods are different. According to my country's national conditions, there are mainly three grounding methods in my country's 6-66KV power generation and distribution systems, one is the neutral point ungrounded method, and the other is the neutral point grounding method. One is the grounding method of the neutral point through the arc suppression coil, and the other is the grounding method of the neutral point through the resistance cabinet. Among them, the neutral point of the system is grounded through the arc suppression coil as the mainstream grounding method, which is widely used. However, how to grasp the quality acceptance of the complete set of arc suppression coils and how to continuously...
