Problems solved by technology

[0002] The transformer adopts the method of electromagnetic winding to increase the output of current, and at the same time avoid the problem that the current output is unstable due to excessive resistance, and its interior adopts a double-layer drum structure to make the winding more balanced. Much higher dielectric strength, the insulating material is immersed in transformer oil, but because the periphery of the resistance ring is covered by transformer oil, but as the transformer oil is used, the oil will gradually age and the sludge in the oil will increase. Affect the fluidity of transformer oil, so that the transformer oil needs to be replaced frequently, and the viscosity of the transformer oil is too small when it is first used, and the flow speed is too fast, which is easy to reduce its closed flash point, and the lower the closed flash point, the easier it is to affect the safety of the transformer

Embodiment 1

[0027] Such as Figure 1-Figure 6 Shown:

[0028] The present invention is a low-voltage torrent coil oil-immersed transformer, the structure of which includes a terminal rod 1, a fixed plate 2, a radiator 3, and a resistance mechanism 4. The terminal rod 1 communicates with the fixed plate 2, and the fixed plate 2 is installed On the surface of the resistance mechanism 4, the heat sink 3 is embedded on the side of the resistance mechanism 4, and the resistance mechanism 4 is provided with a fixed frame 41, a metal rod 42, a moving mechanism 43, an electric coil 44, a magnetic rod 45, and a filling groove 46. ​​Outer shell 47, the electric coil 44 surrounds the outer side of the magnetic rod 45, the upper and lower ends of the magnetic rod 45 are embedded in the fixed frame 41, and the lower end of the fixed frame 41 is embedded in the inner lower end of the outer shell 47 , the filling groove 46 is located inside the casing 47, the moving mechanism 43 is installed inside the...

Embodiment 2

[0036] Such as Figure 7-Figure 9 Shown:

[0037] Wherein, the pressing mechanism a1 is provided with a spring a11, a rubber ring a12, and a fixed shaft a13. The rubber ring a12 is attached to the outside of the spring a11, and the left and right ends of the spring a11 are embedded in the inside of the fixed shaft a13. The fixed shaft a13 is embedded in the upper end of the drainage plate a2, and the middle of the fixed shaft a13 is a fixed shaft. There are four fixed shafts a13, which are divided into two groups. There is a gap between each group, so that the spring When a11 is bent under force, the gap between the fixed shafts a13 becomes larger, so that the sediment is deposited, and the sediment is prevented from flowing when the oil is convected, so as to prevent the convection velocity from being affected.

[0038] Wherein, the storage mechanism 432 is provided with a semicircular block p1, a support rod p2, a placement groove p3, a blocking plate p4, a sealing plate p5...

Abstract

The invention discloses a novel low-voltage coil-wound oil-immersed transformer, the structure of which includes a connecting rod, a fixed plate, a radiator, and a resistance mechanism. The resistance mechanism is provided with a fixed frame, a metal rod, a moving mechanism, an electric coil, a magnetic rod, Fill the tank and shell to slow down the flow speed of the oil, so that the convection force of the oil inside the filling tank is blocked by the moving mechanism, so that the filter mechanism slides on the inside of the sliding track, and at the same time, the force-bearing mechanism rotates outside the fixed rod, so that its convection force If it is blocked, the flow velocity of the oil with too small viscosity is reduced, and the closed flash point is easily reduced by avoiding the excessive flow velocity. By preventing the gap between the plates from slowly settling in the placement tank, the sediment at the lower and upper ends of the pressing mechanism can be obtained. Place it to prevent the sediment from overflowing during the oil convection process and affect its viscosity, prevent the viscosity from slowing down the convection speed, and avoid slow heat dissipation.
