Self-circulating evaporating cooling distribution transformer

Abstract

The invention discloses a self-circulating evaporating cooling distribution transformer, relating to the technical field of transformers. The self-circulating evaporating cooling distribution transformer comprises a transformer body, a base and a grounded rod lifting device, wherein the transformer body is fixed on the base, the grounded rod lifting device comprises a first chute, a first contactroller, a first connection rod, a first electric push rod, a second chute, a second contact roller, a second connection rod, a second electric push rod and a grounded rod, a rotary shaft penetrates the upper end of the grounded rod, a round hole penetrates the middle of the base, and the upper part of the round hole is opposite to the lower end of the grounded rod. The two electric push rods are adopted as a power source so as to drive the middles of the two connection rods to move up and down, so that one end of each connection rod can move in the chute through the contact rollers, the otherend of each connection rod and the grounded rod that are coaxially connected move up and down as a whole, therefore, the grounded rod can insert into and pull out from ground automatically, manual operation intensity is relieved, and the grounded rod is replaced more efficiently.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a self-circulating evaporative cooling power distribution transformer. Background technique [0002] The self-circulating evaporative cooling transformer uses the latent heat of vaporization when the cooling medium evaporates to take away the heat of the winding and iron core, and the heat taken away is condensed into liquid through the condenser and returned to the transformer oil tank. The transformer is often impacted by lightning, and the voltage generated by the impact causes oscillation in the coil, causing the coil to generate a high oscillating voltage that damages the insulation of the transformer and affects the normal operation of the transformer. Generally, grounding devices such as lightning rods and grounding rods are installed. To protect the transformer from lightning impact, the grounding rod needs to be replaced after a long period of use. The replacement o...

The transformer is often impacted by lightning, and the voltage generated by the impact causes oscillation in the coil, causing the coil to generate a high oscillating voltage that damages the insulation of the transformer and affects the normal operation of the transformer. Generally, grounding devices such as lightning rods and grounding rods are installed. To protect the transformer from lightning impact, the grounding rod needs to be replaced after a long period of use. The replacement of the grounding rod is generally done by digging out the grounding rod from the ground, removing the wire connected to the grounding rod, and replacing it with a new grounding rod. After connecting the wires and then burying them in the ground, the whole process is manually operated, which greatly increases the labor intensity of the staff and also reduces the replacement efficiency of the grounding rods
