A self-circulating evaporative cooling distribution transformer

Abstract

The invention discloses a self-circulating evaporative cooling distribution transformer, which relates to the technical field of transformers. It includes a transformer body, a base and a grounding rod lifting device. The transformer body is fixed on the base. , the first connecting rod, the first electric push rod, the second chute, the second roller, the second connecting rod, the second electric push rod and the grounding rod. The top of the round hole faces the lower end of the ground rod. By setting two electric push rods as power sources, the middle parts of the two connecting rods are driven to move up and down, so that one end of the two connecting rods moves in the chute through the roller, and the other end of the two connecting rods is coaxially connected to the grounding rod. The whole up and down movement realizes the automatic insertion and extraction of the ground rod into the ground, which reduces the intensity of manual operation and improves the replacement efficiency of the ground rod.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a self-circulating evaporative cooling distribution transformer. Background technique [0002] The self-circulating evaporative cooling transformer uses the latent heat of vaporization when the cooling medium evaporates to remove the heat of the winding and the iron core, and the removed heat is condensed into liquid through the condenser and returned to the transformer tank. The transformer is often impacted by lightning, and the voltage generated by the impact causes oscillation in the coil, which causes the coil to generate a high oscillating voltage, which 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 shock, the grounding rod needs to be replaced after long-term use. The replacement of the groundi...

Problems solved by technology

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
