10kV固体环网柜 hearymax系列


Brief introduction to the products


Since the greenhouse effect of SF6 is 23,000 times that of CO2, it is explicitly limited by the United Nations Climate Convention and the Kyoto Opinion. In June 2010, the State Grid Corporation of China issued a plan for the development of smart grid equipment systems. It clearly defined the direction and plan for the development of the secondary power distribution equipment, such as environmental protection and maintenance-free. On March 2, 2012, State Grid officially released "12kV Solid Insulated Ring Main Units "Q / GDW-730-2012 enterprise standards. January 2013 State Grid Corporation in the distribution network of agricultural inventory agreement for the first batch of bulk use of solid insulation ring switchgear ,. July 31, 2013 Chinese Premier Li Keqiang presided over the State Council executive meeting to determine "to strengthen the urban distribution network construction, and promote intelligent power grid is one of the six key tasks of urban infrastructure," in November 2013 the State Grid Corporation of distribution network standardization Typical design meeting, explicitly increase the solid insulation ring network cabinet promotion efforts to increase the solid insulation ring network cabinet set up programs. So 2013 is solid insulated ring counter large-scale to the Chinese market in the original year.

Product dvantages

公司研制的hearymax-12系列紧凑型固体绝缘开关设备是新一代小型化、可扩展、免维护、环保型金属封闭开关设备,其主要特征是主回路采用三相纵向布署,将三工位隔离开关和固封真空断路器功能组合在一起。此设备广泛应用于3~12kV三相交流50Hz 电力系统中,适用于箱式变电站、环网配电系统中,也是二次配电KYN28A及SF6环网柜理想替代产品。hearymax-12系列紧凑型固体绝缘开关设备有如下优点:




4.hearymax-12系列开关柜参数目前可达1250A 分断能力31.5kA。


Developed by the company hearymax-12 series of compact solid insulation switchgear is a new generation of small, scalable, maintenance-free, environmentally friendly metal-enclosed switchgear, the main feature is the main circuit using three-phase longitudinal deployment, the three- Switch and solid sealing vacuum circuit breaker function together. This equipment is widely used in 3 ~ 12kV three-phase AC 50Hz power system, suitable for box-type substation, ring network distribution system, but also secondary distribution KYN28A and SF6 ring counter ideal replacement. Hearymax-12 series of compact solid insulation switching equipment has the following advantages:

1. Up and out without the need for cable trench, can be installed in the middle layer of high-rise transformer substation

2. Visual port, clearly visible Safety switch position,

3. Fixed installation maintenance-free, small footprint,

4.hearymax-12 series switchgear parameters are currently up to 1250A breaking capacity of 31.5kA.

Can replace most of the SF6 semi-insulated switchgear and KYN28A-12 end-user market, practice is the touchstone of the test of truth, through the domestic provinces and cities in the bulk application of important projects, fully proved hearymax-12 series of compact solid insulation switchgear with safe, Intelligent, flexible, environmental protection, anti-harsh environment, maintenance-free, and other performance advantages, and its surplus was more users of all ages. In the future to determine the leadership of Hang-hyun green energy industry, to create the grand Hyun-hyun international brand vision. The accumulation of good prospects for technical reserves, the vacuum interrupter and epoxy solid seal two perfect integration of technology and continuous improvement, cast solid insulation vacuum interrupter ring cabinet domestic initiative, the international leading industry position, will rely on performance Excellent products, three-dimensional smooth channels, flexible strategy should be comprehensive advantages, and continue to guide China's new era of secondary distribution.
