Description

Technical Field

[0001] The utility model relates to the field of manufacturing insulating plate pads for oil-immersed transformers, in particular to an insulating paperboard elastic press. Background Art

[0002] Insulation cardboard is an important insulating material, which is widely used in electrical equipment such as motors, transformers, capacitors, etc. Its main purpose is insulation isolation, support and fixation to ensure the safe and reliable operation of the equipment. Insulation cardboard is usually required to have good mechanical strength, heat resistance and insulation properties.

[0003] At present, there are many processing methods for insulation boards, such as hydraulic press processing. Hydraulic presses can complete the production of a large number of insulation boards at one time, greatly improving production efficiency. At the same time, since the working principle of the hydraulic press is to transmit pressure through liquid, the processing process is smooth, the pressure is high, and the adjustability is strong. At the same time, the hydraulic press is easy to operate, which reduces the skill requirements for operators and also reduces the risks of manual operation.

[0004] However, there are still some problems with hydraulic press processing. For example, the hydraulic press cannot be moved, and the insulation board can only be cut after it is dried. In this way, the pads pressed to the required size do not need to be baked again, and the thickness of the pads will not change. However, the number of insulation boards to be dried must be predicted in advance. Too much baking will be a waste, and too little baking will be insufficient. Moreover, the cutting and compression must be completed in a short time, otherwise the cardboard will easily absorb moisture, especially during the return of the south wind. After absorbing moisture, it must be dried again, so the thickness of the pads will easily change. Utility Model Content
