Embodiment 1
[0026] see Figure 1 ~ Figure 4 , an isolation transformer for a high-voltage inverter cabinet, including a casting winding 1, an iron rod 2, a core post 3, a terminal post 4, a primary coil 5, a secondary coil 6, a high-voltage cable 7 and a pull rod 10; the casting winding 1 is set on On the core column 3; the two ends of the core column 3 are respectively connected with two iron poles 2; the two iron poles 2 are connected through the tie rod 10; the primary coil 5 and the secondary coil 6 are arranged in the pouring winding 1; the primary coil 5 and the secondary The coil 6 is connected to the high voltage cable 7 through the first terminal 4 .
[0027] The casting winding 1 is in the shape of a square tube. A pair of lugs 11 with an inner hollow depth of 100 mm extend outward from one end of the casting winding 1 . The ear protector electrically isolates the terminal post and the iron pole, which can meet the 50kV withstand voltage requirement. The ear protector 11 is fi...

The invention provides a high-voltage inverter cabinet isolation transformer. The high-voltage inverter cabinet isolation transformer comprises a pouring winding, an iron cape, a core column, a binding post, a primary coil, a secondary coil, a high-voltage cable and a pull rod. The pouring winding is sleeved on the core column. Two ends of the core column are respectively connected with the two iron gardens. The two iron gardens are connected through a pull rod. A primary coil and a secondary coil are arranged in the pouring winding. The primary coil and the secondary coil are connected with ahigh-voltage cable through a first binding post. The ear protection structure adopted by the invention is a recessed insulation structure, and is used for electrically isolating the binding posts from the iron cape, so that the product size and space are greatly reduced, and the space of the whole cabinet is saved. The eccentric winding design is adopted, that is, only one core column is providedwith the pouring winding, and the unit volume power of the product is improved. Compared with a traditional high-voltage isolation transformer, the high-voltage isolation transformer is simple in structure, light in weight and low in manufacturing cost. Materials can be effectively saved, and great economic benefits are generated.
Description
technical field [0001] The invention relates to the technical field of high-voltage power control, in particular to an isolation transformer for a high-voltage inverter cabinet. Background technique [0002] In recent years, the country has attached great importance to the work of military-civilian integration, vigorously implemented the development strategy of military-civilian integration, and formed a development pattern of military-civilian integration with all elements, multiple fields, and high efficiency. The high-voltage power supply control cabinet used for advanced military equipment has high performance requirements, the voltage inside the cabinet is above 10kV, and the power supply of the electronic control unit in the cabinet is only 220V. Traditional transformers mostly generate high voltage on the power supply side, and the iron core and iron yoke are connected to low potential. Traditional transformer structure design and insulation treatment methods are used...
