为了缩小铁路变电所装置的体积、降低损耗、便于维修,日立公司研制出了体积小、坚固耐用的SF6GIS(气体绝缘开关装置),噪声低、效率高的电气化铁路变压器和数控电源柜。为满足目前不断增长的环保、安全、高效、坚固、便于维修设备的需求,我们研制出了(1)环保型防故障硅变压器;(2)无SF6温室气体环保型GIS和坚固型叠放式SWGR(开关装置);(3)一种新的不含PFCs(全氟化碳气体)冷却液的生态型低损耗整流器;(4)BBU(组合单元),通过采用标准单元的保护控制器,实现在线维修。
In order to reduce the size of the railway substation equipment, reduce losses and ease of maintenance, Hitachi has developed a small, rugged SF6GIS (gas-insulated switchgear), low noise, high efficiency electric railway transformers and CNC power cabinet. To meet the current growing demand for environmentally friendly, safe, efficient, robust and easy to repair equipment, we have developed (1) environmentally friendly fail-safe silicon transformers; (2) environmentally friendly SF6-less greenhouse gas and rugged stacked SWGR (switchgear); (3) a new eco-type low-loss rectifier without PFCs (perfluorocarbon gas) coolant; (4) BBU (combination unit) with a standard unit protection controller, Realize online repair.
