[Abstract]:C-GIS-Cubicle type Gas Insulated Switchgear gas insulated metal closed switchgear) is a set of electrical appliances derived from the combination of GIS(Gas Insulated Switchgear gas insulated metal closed switchgear and conventional switchgear technology. Environmental pollution is small, maintenance-free and easy to install, and so on, it has been widely used in the distribution system of medium voltage power grid. With the increasing awareness of environmental protection in the whole society, Environmental friendly power grid equipment is also gradually popularizing .SF6 gas, because of its Greenhouse Effect, its application in the field of electrical equipment has limitations. At the same time, with the development of the energy Internet, the technical parameters of intelligent power grid to electrical equipment, In order to solve the problem of environmental protection of insulation medium used in electrical equipment and improve the insulation and operation characteristics of products, it is necessary to meet the requirements of power grid operation. In this paper, the insulation structure and its monitoring system of SF6 substitute gas switch equipment for traditional C-GIS equipment are studied. The main structures of traditional C-GIS equipment include interrupter, operating mechanism, three-station switch, busbar and cabinet, etc. This paper takes the structure improvement design of traditional C-GIS arc-extinguishing system and the engineering application demand of intelligent and networked switchgear as the technical route. This paper puts forward a C-GIS design scheme to replace the insulating medium of SF6 inflatable cabinet by nitrogen with environment-friendly characteristics. The structure of the arc-extinguishing system of switchgear is analyzed by electrostatic field finite element analysis to make it meet the requirements of insulation standard. In order to solve the contradiction between environmental protection and insulation reliability, the structure of three-position switch is designed and analyzed by electrostatic field finite element method. The CAN bus technology is introduced. This paper presents an open and multi-hardware compatible intelligent switchgear system. Its good compatibility and transparency realize the information communication and network management of the intelligent switchgear equipment from the system level. In addition, based on the MATLAB platform, the intelligent switchgear system is developed. In this paper, a software platform for electric field analysis using finite element method to solve electrostatic field in parallel is put forward, and insulation design and verification analysis of gas chamber and three-position switch of circuit breaker are carried out, and the intelligent C-GIS CAN bus system is built and tested independently by using CANoe software platform. It provides a reference scheme for intelligent equipment network management and information communication from the system level.
