Discharging device and transformer substation

Abstract

The invention relates to a discharging device, which comprises a conductive barrel, a current sensor, a container and a current equalizing part, a transformer is electrically connected with the ground through the conductive barrel, and the current of the transformer can be led into the ground through the conductive barrel and the conductive liquid by injecting the conductive liquid in the container into the conductive barrel, so that the discharging and voltage reduction operation is carried out on the transformer. Due to the fact that the flow equalizing part is arranged in the conductive barrel, when small-flow conductive liquid enters the conductive barrel, part of the conductive liquid is deposited above the flow equalizing part under the blocking effect of the flow equalizing part, and therefore the conductive liquid makes full contact with the conductive barrel. Furthermore, the conductive liquid flows downwards through a gap formed between the flow equalizing piece and the inner wall of the conductive barrel, and the conductive liquid flows downwards along the inner wall under the flow guide effect of the inner wall, so that the risk of flow cutoff when the flow of the conductive liquid is small is reduced, the conductive liquid can stably flow to the grounding terminal, the discharge effect of the conductive liquid is ensured, and the service life of the conductive barrel is prolonged. The use reliability of the discharging device is improved, and the safety of power transformation equipment such as a transformer is further improved.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a discharge device and a substation. Background technique [0002] Existing substations usually set up a diversion tube between the substation equipment and the ground, and the conductive fluid flows into the ground by conveying the conductive fluid in the diversion tube to discharge the substation equipment to ensure the substation substation equipment and personal safety .
