American substation: overload capacity, allowing overload 2 times 2 hours, overload 1.6 times, 7 hours without affecting the box life.
The elbow type plug joint can be used for connecting the cable of the high tension inlet wire and can be used as a load switch in an emergency, and can be pulled out and inserted.
With double fuse protection, the plug-in fuse (BAY - O - net) for the UNIKA fuse (temperature, current) protection box to change the two side of the short-circuit fault. Backup current limited protective fuse (ELSP) protection box is an internal fault that is used to protect high voltage.
General use of transformer oil of high fire point (FR3).
All components of fuses for high voltage load switch protection are placed inside the same oil tank with the transformer core and winding.
The European transformer box is equipped with an independent transformer room. The transformer room is mainly composed of transformer, automatic temperature control system, lighting and safety fence.
During the operation of the transformer, will produce a lot of heat in the box to give the transformer room, so heat, ventilation of transformer room is the European box changes should focus on the problems in the design of transformer operation, Everfount; the heat produced by the transformer room temperature rising, especially the ambient temperature, temperature increased faster, so only rely on natural ventilation can not guarantee the safe and reliable operation of the transformer; European box changes in design, in addition to smaller transformer box with natural ventilation, generally designed temperature protection with forced ventilation measures to solve them. The system is mainly composed of measuring devices, transformers, room temperature, oil temperature can be. Then, through manual and automatic control circuit, whether the exhaust fan needs to be put into use, set the control according to the setting range of the reliable and safe operation temperature of the transformer.
European box changes, which can be used in transformer oil immersed transformer, dry-type transformer can be used, but because the dry transformer price is higher, so the user does not have special requirements, should be the first choice of oil immersed transformer, to reduce the manufacturing cost. Transformer capacity is generally at 100-1250KVA is appropriate, the maximum should not exceed 1600KVA
The product has the advantages of safe and reliable operation, convenient maintenance, beautiful appearance, etc. the utility model has the advantages of small size, small occupation area, large selectivity, short installation and debugging cycle, etc..
