Product Model: SC (B) 10-30 / 10 9. Brand: Adams Sutton core quality cold-rolled grain-oriented silicon steel, silicon steel core 45-degree miter joints, along the magnetic flux silicon joint direction by windings form ⑴ ⑵ wound epoxy resin plus quartz sand filling pouring ⑶ glass fiber reinforced epoxy resin cast (ie thin insulation) ⑷ multi-strand glass fiber impregnated with epoxy resin wound (generally use 3, because it can effectively prevent cracking of casting resin, improve equipment reliability) high voltage winding generally cylindrical multi-layer or multi-segmented structure generally use low voltage winding or foil layered structure ⒈ open type. is A common form of the body of their direct contact with the atmosphere, adapted to the relatively dry and clean room, (ambient temperature of 20 degrees, relative humidity should not exceed 85%), generally from the cold air and air-cooled two cooling way. ⒉ enclosed. is living in a closed shell, not in direct contact with the atmosphere. (due to seal poor heat dissipation is mainly used for mine it belongs to the explosion-proof) ⒊ pouring ceremony. with epoxy or Other cast resin as the main insulation, simple structure, small volume, suitable for small capacity transformers. Features Construction temperature control safe operation of the transformer and its dry-life system depends largely on the transformer winding insulation safety reliability. Cooling dry type transformer cooling mode is divided into natural air cooling (AN) and forced air cooling (AF). When natural air cooling, the transformer can be long-term continuous operation at nominal capacity. When forced air cooling, transformer output capacity can be increased by 50%. Suitable for intermittent overload operation, accident or emergency overload operation; due to overload load loss and impedance voltage larger increase in the non-state economy, it should not make it in a long time continuous overload operation.

However, simply relying on input materials to reduce iron loss or copper loss, we think is desirable. (2) High reliability: electrical products, especially the transformer, its operational reliability is particularly important. In the electromagnetic theory and computation, wave process, casting process, hot temperature, partial discharge mechanism, quality assurance system, reliability engineering and other aspects of a lot of basic research, actively reliability certification, and further improve the reliability of dry-type transformers, The people's unremitting pursuit. (3) the environmental characteristics of certification: based on European standards HD464 conduct weather dry-type transformers (C0, C1, C2), resistance to environmental (E0, E1, E2), refractory study (F0, F1, F2) properties and certification. (4) Large capacity: 2,500KVA distribution transformer capacity is usually less. With the city electricity load increasing, urban and regional substations more in-depth urban centers, residential areas, factories, mines and other large and medium load centers, 35KV high-capacity regional supply dry-type power transformer will be widely applied. Shunte has produced nearly ten 35KV 16,000 / 24,000KVA large capacity becomes dry. (5) Multi-functional and intelligent: with only from a single transformer substation functions, combined with the versatility of forced air-cooled, protective housing, power measurement, computer interface, enclosed bus, and other low-voltage side outlet Transformer development; introducing TTU intelligent interface with data processing, state control, status display and other functions, so that the transformer has become a multi-functional intelligent, ready to run in the best state of the electrical equipment. (6) multi-field development: mainly from a distribution transformer, excitation transformer to power plants, transformer plant, rail traction rectifier transformer, electric furnace large current change, nuclear power plant, marine, oil platforms with other special-purpose transformers and more sectors. In recent years SUNTEN has developed and mass production of these particular products in many fields.

Usually we say that ground zero lines are drawn from the transformer neutral point. (Eg transformer cabinet and the cabinet should be connected to the corresponding earth sign). Check the input and output lines to confirm correct. 4, the first no-load electricity, observe the test input and output voltages to meet the requirements. While observing whether there is abnormal sound inside the machine, sparking, odors and other non-normal, if unusual, immediately disconnect the input power. 5, when the load test is complete and functioning before the access load.
