Abstract
The utility model provides a laminating insulation wood plate for a transformer. The laminating insulation plate for the transformer is characterized by comprising two or more layers of beech plates. A layer of binder agent is arranged between every two layers of the beech plates. The laminating insulation wood plate for the transformer has the advantages of being small in density, high in mechanical strength and oil absorption rate, fast in oil absorption speed, easy to be dried in vacuum and immersed in oil, easy to process, low in medium damage and high in insulation strength.
Description
Technical field
The utility model relates to transformer with the lamination plank that insulate.
Background technology
According to State Grid Corporation of China's " 12 " Electric Power Network Planning and the report of the year two thousand twenty long-range objectives; During " 12 "; State Grid Corporation of China will increase 300,000,000 kilovolt-amperes of 330 kilovolts and above transmission line 60,000 kms, power transformation capacity newly, estimate that the annual requirement of transformer industry is 3.6 ~ 400,000,000 kilovolt-amperes.
At present, homemade lamination birch plate because fiber short and mixed, be unfavorable for oil suction, the not good transformer that can not be used for more than 220 kilovolts of pull resistance.
Summary of the invention
The purpose of the utility model is to provide a kind of low dielectric loss high insulation resistance electrical laminated plate.
The utility model provides a kind of transformer with the lamination plank that insulate, and it is characterized in that: comprise two-layer or two-layer above beech plate, between every two-layer beech plate a layer binder is arranged.
The beech fiber is directly long again, has higher bending resistance and tensile property.
The transformer that the utility model provides is with the lamination plank that insulate, and its beech plate is preferably the beech plank, beech wood have higher anti-bending strength and workability can, fiber hollow, impurity is few, the finished product oil absorbency is high.
The transformer that the utility model provides is with the lamination plank that insulate, and its binding agent is preferably phenol formaldehyde resin, CF or technical phenol formaldehyde resin, and its thermal endurance class is more than the A level, more is applicable to high-tension transformer.
The transformer that the utility model provides is with the lamination plank that insulate, and its phenol formaldehyde resin, CF or technical phenol formaldehyde resin are preferably pure dissolubility phenolic resins or water soluble phenol resin, to increase shearing strength and pliability.
The transformer that the utility model provides is with the lamination plank that insulate, and its advantage is: density is little, and mechanical strength is high, and oil absorbency is high, and speed of oil absorption is fast, is convenient to vacuumize and oil immersion, is prone to processing; Being situated between, it is low to decrease, and dielectric strength is high.
Description of drawings
Fig. 1 is the structural representation of transformer with lamination insulation plank.
Embodiment
Transformer is with the lamination plank that insulate, and its structure is as shown in Figure 1, comprises three layers of beech plank 1, one deck alcohol dissolubility phenol formaldehyde resin binding agent 2 is arranged, promptly two-layer pure dissolubility phenol formaldehyde resin binding agent 2 between every two-layer beech plate 1.
Claims (4)
