An outdoor oil-immersed power transformer

Abstract

The invention provides an outdoor oil-immersed power transformer. The outdoor oil-immersed power transformer comprises a bottom plate, a transformer body, a contact unit, an outer limiting basket, a limiting unit, a fixing unit, a clamping unit, a bunching unit, a water guide unit and a sliding pull plate. The problem that in the using process of the transformer, the transformer is affected by moisture outdoors for a long time, moisture enters the transformer, the insulating property is further reduced, and even short circuit is caused can be solved; and internal parts of a transformer are easy to damage, and an existing transformer body is inconvenient to pull and maintain. Therefore, messy wires in the device are very easy to fall off during maintenance, and secondary damage is caused; and the service life of the oil-immersed transformer is shortened.

Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to an outdoor oil-immersed power transformer. Background technique [0002] The low-voltage windings of oil-immersed transformers generally adopt a cylindrical structure with copper foil around the shaft, except for small-capacity copper wires; the high-voltage windings adopt a multi-layer cylindrical structure, so that the ampere-turn distribution of the winding is balanced, and the magnetic flux leakage is small. High mechanical strength and strong short circuit resistance. [0003] Most of the existing oil-immersed transformers are placed outdoors, which leads to the following problems during the use of the transformer: the transformer is affected by moisture in the outdoors for a long time, causing the moisture to enter and further cause the insulation performance to decline or even cause the risk of short circuit; The internal parts of the transformer are ea...

[0003] Most of the existing oil-immersed transformers are placed outdoors, which leads to the following problems during the use of the transformer: the transformer is affected by moisture in the outdoors for a long time, causing the moisture to enter and further cause the insulation performance to decline or even cause the risk of short circuit; The internal parts of the transformer are easily damaged, and the existing transformer body is inconvenient to pull out for maintenance; resulting in the internal messy wires being easily detached during maintenance, causing secondary damage; reducing the service life of the oil-immersed transformer
