Since the smart grid was written into the government work report in 2010, and smart grids have risen from corporate behavior to national strategies, the smart grid has become the focus of China's power grid development and the focus of the power industry. In the end, what does a smart grid look like and how do we build a smart grid? However, it is an indisputable fact that the smart grid will bring about a revolution in electrical equipment. So what kind of electrical equipment meets the requirements of smart grid construction, it can be seen from the solid insulation ring network cabinet that was listed in the “12th Five-Year Plan†of the State Grid Corporation.
Relevant data show that the concept of smart grid covers improving the science and technology content of the grid, improving the efficiency of comprehensive utilization of energy, improving the reliability of power supply of the grid, promoting energy conservation and emission reduction, promoting the use of new energy, and promoting the optimal allocation of resources, etc., and ultimately achieving the benefits of the grid. Maximizing social benefits, making people's lives easier and more efficient, and making society more energy-efficient and environmentally friendly. It can be seen that the security, strong, environmental protection, and intelligence are undoubtedly the key words of the smart grid, and the solid ring network cabinet has greatly improved in these aspects than the previous products. The concept of solid insulated ring network cabinet was proposed by Beijing Shuangjie Electric in the country, and took the lead in two years and seven months. The Shuangjie Electric's solid insulated ring network cabinet not only filled the domestic gap, but also won four domestic invention patents. And two utility model patents, and obtained international invention patents.
Smart Grid: security is a prerequisite for <br> <br> safety equipment is intelligent grid security and stability and an important foundation for social and reliable power supply, the current smart grid security standards related to China's development, technology research and industry promotion are actively promoting . The most commonly used inflatable ring network cabinet nowadays is an SF6 gas ring network cabinet. It uses sulfur hexafluoride as the insulating medium. Although after several years of development, the quality has been continuously improved, it is often encountered during the actual operation. Leakage problems, gas leakage will cause great hidden dangers and dangers to the operation of the switch. Relatively high pressure GIS equipments are centralized and easy to manage. Inflatable ring network cabinets are widely distributed. It is difficult to perform full-scale supervision and management in actual operations, and it also brings hidden troubles to operation. Shuangjie Electric's solid insulated ring main cabinet has completely eliminated the SF6 gas and its corresponding gas box components in terms of structural principle. The insulating sleeve is used to solidify the switch parts, and the closed busbars connect the various circuits to achieve fully-enclosed and fully-insulated. In terms of manufacturing, phase and phase are separated; from the electrical point of view, there is no short circuit between phases. It does not have pressure air boxes, pressure relief valves, anti-skid parts, etc., and it is truly maintenance-free.
Smart Grid: <br> <br> is to ensure a strong smart grid called the strong smart grid, smart grid is the foundation of a strong, intelligent power grid protection. Shuangjie Electric's solid-insulated RMUs have outstanding resistance to harsh environments compared to SF6 RMUs, and they have obvious advantages in harsh environments such as severe cold, high altitude, humidity, and strong winds. In the event of a weather of minus 40 degrees, SF6 in the SF6 RMU will liquefy, and the air pressure in the air box will also decrease, resulting in a decrease in insulation and arc extinguishing performance. At a high altitude, the SF6 RMU will automatically expand due to the reduction of atmospheric pressure, causing air leakage and short circuit. Because the solid ring cabinet does not use SF6 gas, there is absolutely no concern in this regard. In strong winds and sands, wind and sand can easily destroy the transmission equipment of the gas ring network cabinets. For example, the gears and chains are jammed, causing the cabinets to solidify and affect the use of the equipment. The solid insulated ring main cabinet is completely enclosed by the entire mechanism and there are no transmission parts outside, and it can be used with ease in strong wind and sand environments. In the coastal or high-humidity areas, RMUs are most afraid of rust caused by springs, gears, etc., resulting in unusable equipment. The solid-insulated RMUs pass through salt spray test chambers to imitate rust tests under conditions of high salt and high humidity. There will be no rust in the year or 30 years.
Smart Grid: Environmental Protection is the Direction <br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br> As a major innovation in transforming the development mode of the power grid, the smart grid also imposes requirements on environmental protection. At present, more than 90% of the medium voltage full-enclosed ring network cabinets rely on SF6 gas as the insulating medium. This gas will inevitably leak and discharge in the process of inflating, running, and recycling, and become a major source of pollution in the atmospheric environment. According to the "United Nations Framework Convention on Climate Change" and the "Kyoto Protocol," the greenhouse gas value (GWP) of SF6 among the six greenhouse gases that cause global warming is the highest, which is 23,900 times the impact of CO2 on the atmosphere. Countries around the world have legislation to reduce or even prohibit the use of SF6 in power equipment. Shuangjie Electric's solid insulated ring main cabinet is completely independent of sulfur hexafluoride gas in terms of its principle of manufacture. It provides the basic guarantee for the emission reduction and environmental protection in the field of distribution network equipment and is in line with the requirements of smart grid construction.
Smart Grid: Intelligence is the key
The smart grid is a complete intelligent power system covering all aspects of power generation, transmission, power transformation, power distribution, electricity use, dispatching, and communication information. Intelligence is an important key element. The automation of distribution network automation control must achieve electrical control. Inflatable ring network cabinets are not the same as the manual and electric structures. Changing the manual mode to the electric mode is extremely difficult. At present, many inflatable SF6 ring network cabinets can not meet the needs of automation of distribution network transformation. Shuangjie Electric's solid insulated ring network cabinet is extremely intelligent, and the site can be connected to PT power according to user needs. The cable connector can realize on-line monitoring, giving the user the temperature value at the scene, at the same time the data arrives at the control terminal, the operation and maintenance is strengthened, and many practical problems are solved for the user. Solid insulation ring network cabinet load switch instantaneous breaking, to provide protection for multi-level distribution automation.
To grasp the trend is to grasp the future. As a country with independent intellectual property rights and the world's leading electrical equipment, Shuangjie Electric Solid Insulated Ring Network Cabinet will undoubtedly play an important role in the construction of smart grids and in the characteristics of smart grids in China. No wonder industry experts have high hopes for Shuangjie Electric that it is expected to become a leader in the electrical equipment revolution triggered by the smart grid.
