Description

Technical Field

[0001] The utility model application relates to the technical field of insulating tubes, in particular to an anti-aging insulating tube for a transformer coil skeleton. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. It is the basic equipment for power transmission and distribution and is widely used in industry, agriculture, transportation, urban communities and other fields. Among them, the transformer coil is the path of current, and the induced electromotive force is generated by passing current through the winding. It is mainly used to convert AC voltage, current and impedance. When the coil is wound, it is generally arranged in layers along the axial direction and continuously wound on a tubular frame.

[0003] Since the coil will generate a certain amount of heat when it is running, the heat dissipation performance of the insulating skeleton tube is required to be high. However, most of the existing insulating tubes are hollow tubes, which mainly rely on their own material to dissipate heat, resulting in the heat dissipation performance of the insulating tube is very limited. When the coil is running, the heat cannot be discharged quickly and in time, which easily leads to large losses of the coil and the insulating tube when the coil is running. Summary of the invention

[0004] In order to solve the problem that the existing anti-aging insulating tube for transformer coil skeleton has poor heat dissipation performance during use, the utility model provides an anti-aging insulating tube for transformer coil skeleton to solve the above problem.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An anti-aging insulating tube for a transformer coil skeleton comprises an insulating tube body, support guide plates are fixed at the front and rear ends of the insulating tube body, a plurality of ventilation cavities are equidistantly provided inside the insulating tube body, ventilation loops communicating with the ventilation cavities are provided inside the front and rear support guide plates, and air inlets and outlets are fixedly provided on the outer side walls of the front and rear support guide plates.

[0007] Furthermore, the insulating tube body includes an insulating support inner tube, a reinforced outer tube layer, an anti-corrosion insulating coating, an anti-aging and scratch-resistant coating, a reinforced inner tube layer and an anti-aging and anti-corrosion inner tube layer. The outer side of the insulating support inner tube is wrapped and fixed with the reinforced outer tube layer, and the outer side of the reinforced outer tube layer is wrapped and coated with an anti-corrosion insulating coating, the outer side of the anti-corrosion insulating coating is wrapped and coated with an anti-aging and scratch-resistant coating, the inner side of the insulating support inner tube is fixed with the reinforced inner tube layer, and the side of the reinforced inner tube layer away from the insulating support inner tube is wrapped and fixed with the anti-aging and anti-corrosion inner tube layer.

[0008] Furthermore, both ends of each ventilation cavity and the opposite ends of the two air inlets and outlets are connected to the inside of the ventilation ring channel, and the thickness of the ventilation ring channel is smaller than the thickness of the supporting guide plate.

[0009] Furthermore, each of the ventilation cavities is configured to be an arc shape that matches the inner circle of the insulating tube body, and the width of each of the ventilation cavities is equal to the width of the insulating tube body.

[0010] Furthermore, the two air inlets and outlets are respectively located on both sides of the front and rear support guide plates, one end of the air inlet and outlet is externally connected to the fan outlet, and the other end of the air inlet and outlet is internally threadedly connected to a dustproof inner net box.

[0011] Furthermore, the thickness of the anti-aging and anti-scratch coating is greater than the thickness of the anti-corrosion insulating coating, the ventilation cavity is opened inside the insulating support inner tube, and the thickness of the reinforced outer tube layer is equal to the thickness of the reinforced inner tube layer.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, a plurality of ventilation cavities are arranged equidistantly inside, so that after the airflow enters the tube body through the ventilation loop and the air inlet and outlet, the internal heat can be taken away, thereby ensuring the heat dissipation inside the insulating tube and the heat dissipation effect inside the tube body, solving the problem that the existing anti-aging insulating tube for transformer coil skeleton has poor heat dissipation performance during use, prolonging the service life of the coil and the insulating tube, and avoiding overheating that affects the normal operation of the coil.

[0014] 2. In the utility model, the reinforcing layer of the inner and outer wrapped design of the insulating support inner tube can improve the supporting strength of the tube body. Combined with the anti-corrosion design on the inner and outer sides, the anti-corrosion and anti-aging properties of the insulating tube body can be improved during daily use, effectively preventing the tube body from being corroded. At the same time, the outermost thickened anti-aging and anti-scratch coating can also improve the anti-aging properties of the insulating tube. BRIEF DESCRIPTION OF THE DRAWINGS
