Multipurpose combined protection type transformer

Abstract

The invention belongs to the field of power equipment, and particularly relates to a multipurpose combined protection type transformer which comprises a transformer body, a base is mounted at the bottom end of the transformer body, a box is fixedly mounted on the base, components are arranged in the transformer body, the box wraps the outer sides of the components, the box is made of insulating materials, and the transformer body is made of insulating materials. An observation window is arranged on the box body, driving plates which are uniformly distributed are mounted in the annular side wall of the box body, and spikes are arranged at the end parts of the driving plates and are positioned on the outer side of the box body; components in the transformer main body are wrapped by the insulated box body, the situation that short circuit of the transformer is easily caused after animals such as rats and snakes bite or make contact with the components is improved, the rats and snakes are arranged on the outer side of the box body, so that the animals such as the rats and the snakes are difficult to climb to the box body, and the safety of the transformer is improved. The conditions that the box body is damaged and components are exposed outside after animals such as rats and snakes bite and step on the box body for a long time are improved, and the use is safer.

Description

technical field [0001] The invention belongs to the field of electric equipment, in particular to a multi-purpose combined protection transformer. Background technique [0002] Transformers in urban substations are mostly space-saving, lightweight, easy to handle, dry-type transformers. The high-voltage side gears of dry-type transformers and the connection of the same connecting rod are exposed and are close to the ground. Small animals such as mice and snakes climb to live parts, causing short-circuit faults in transformers, which is one of the main reasons for power outages on the user side of transformers. [0003] A Chinese patent with publication number CN111128520A discloses an integrated protective dry-type transformer and a protective device. During the installation of the transformer, the transformer body is put into the box; the first connection terminal and the second connection terminal are respectively Correspondingly extend from the first outlet and the secon...

AI Technical Summary

Problems solved by technology

[0004] There are still some problems in the above-mentioned integrated protective dry-type transformer and protective device. Although the first protective cover and the second protective cover are installed, the protective cover itself does not have the function of repelling animals. In the actual operation of the substation, it may Animals such as rats and snakes have bitten and trampled on the protective cover for a long time, resulting in the failure of the protective cover. Especially in the cold outside environment, animals have a stronger desire to enter the transformer to escape, and animals are more likely to tear In the case of biting equipment, the above-mentioned integrated protective dry-type transformer and protective device have not effectively solved this problem, and the protective function is limited.
