A dry-type transformer with protective dehumidification function

Abstract

The invention discloses a dry transformer having the protection dehumidifying function. The dry transformer includes a protection device, shunting connection pieces, a high voltage lead, a high voltage insulator, a conductive row, an upper clamp, a low voltage coil, a high voltage coil, a base protection shell and a connecting frame. The dry type transformer having the protection dehumidifying function is advantaged in that a lead coil is positioned and mounted in the operating position through a fixing plate, a pressing member is closely attached to a high voltage lead end, moisture in the air is then sucked up by an absorbent member, that surrounding of the high voltage lead and each set of the shunting connection pieces is in a dry state is guaranteed, discharge accidents caused by excessive moisture in the air is prevented, safety of the dry transformer is improved, a clamping plate and a connecting panel are closely attached to a lower end of the transformer to protect the bottomof the transformer, small animals are prevented from entering a transformer room through a cable trench below the transformer in operation, safety and efficiency of transformer operation are improved,and occurrence of accidents is reduced.

Description

Technical field [0001] The invention relates to the field of transformers, in particular to a dry-type transformer with protection and dehumidification functions. Background technique [0002] Dry-type transformers are devices that use the principle of electromagnetic induction to change the AC voltage. They are widely used in high-rise buildings, airports, terminals, CNC machinery and equipment and other places. They have strong short-circuit resistance, small maintenance workload, and high operating efficiency. It has the advantages of small size and is often used in places with high performance requirements such as fire prevention and explosion protection. However, the high-voltage leads on the high-voltage lead ends of the existing dry-type transformers and the connecting pieces of each component are generally exposed in the air, so that the high-voltage leads and the tap connecting pieces are prone to excessive moisture in the air. Discharge accidents are caused, and the sa...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies existing in the prior art, the object of the present invention is to provide a dry-type transformer with protection and dehumidification function, so as to solve the problem that the high-voltage lead wires on the high-voltage lead end of the existing dry-type transformer and the connecting pieces of each group are generally It is exposed in the air, so the high-voltage lead wires and tap connection pieces are likely to cause discharge accidents due to excessive moisture in the air, and the safety is very poor; and the bottom of the transformer is not protected, so that small animals can pass through the cable trench under the transformer Entering the transformer room, when the transformer is running, it is prone to accidents
