Supply box-type substation

Box-type substation is suitable for residential areas, urban public change, bustling downtown, construction supply, the user according to different conditions, load level selection box-type variable. Since the box-type substation since the advent of extremely rapid development in European countries accounted for 70% of the distribution transformers, the United States accounted for 90%. The rapid development of China's urban modernization, and constantly upgrading urban distribution network, will be widely used. Customers can request made of different shapes, styles environmental conditions (1) 1 normal environmental conditions. Maximum ambient air temperature: + 40 ℃, lower limit: -25 ℃. 2. Altitude: not exceed 1000m. 3. Relative ambient temperature: air humidity less than 90%. 4. Outdoor wind speed does not exceed 35m / s. 5. Ground inclination is not greater than 5 °, no severe vibration and shock-free place. 6. Non-conductive dust, non-explosive, non-corrosive metal and electrical components of gas sites. (2) special working conditions when used under normal environmental conditions exceed the prescribed consultation by the user and the manufacturer. Product Design Features 1. Housing foreign advanced technology and designed according to the actual situation. Having a solid, heat ventilation, good performance, dust, small animals, moisture, appearance, and easy maintenance. Housing Material There are many options. Such as: aluminum, steel, composite panels, stainless steel, non-metallic materials (glass fiber cement) and the like. 2. Generally use high side load switch, vacuum circuit breakers can also be used, and there is a full range of anti-misuse features. Device can be used XGN15-12 SF6 Ring Main Units, HXGN2-12 RMU, XGN66-12 metal-enclosed switchgear and other open switchgear as a high-side power distribution unit, the low-pressure side can be used GGD.GCK, MNS, GCS and other switchgear unit as an output transformer can be used transformer oil or dry transformers. 3. Complete substation protection performance, easy operation, high and low pressure measurement to choose from, according to user requirements can be equipped with automatic reactive power compensation device, can be dynamic or static mixing mixing compensation compensation. 4. Box roof design for the double structure, mezzanine full of foam, with good thermal insulation. High and low pressure chamber in its interior design separate roof, indoor transformer with anti-condensation and automatic temperature control surveillance, heating and cooling devices. 5. Box with natural ventilation, forced ventilation equipment can also be added. Corresponding to the outer side door and louver position is equipped with anti-dust.
