A low-voltage torrent coil oil-immersed transformer

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.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a low-voltage torsion coil oil-immersed transformer. Background technique [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 p...
