[0002] In order to transmit electric energy to thousands of households, distribution transformers or prefabricated substations including distribution transformers must be widely used. These transformers or prefabricated substations generally occupy a large area and affect the appearance of the environment; especially overhead high-voltage lines At present, many three-phase distribution transformers on both sides of the street are installed on the platform bracket supported by the column, and the low-voltage switchgear is hung outside, which not only affects the appearance, but also occupies a large area and is inconvenient for maintenance and use.

Abstract
The invention relates to a vertical column type transformer. The vertical column type transformer is characterized by comprising a vertical column-shaped outer casing, a first conductive column, a second conductive column, a third conductive column, a fourth conductive column, a transformer body, an SW low-voltage switch, a PT protecting device, a kWh kilowatt-hour meter, and a fixing device, wherein the inside of the outer casing is provided with a separating plate to separate the inside of the outer casing into an upper mounting area and a lower mounting area, the first conductive column, the second conductive column, the third conductive column and the fourth conductive column are respectively arranged on the separating plate, the transformer body is arranged in the upper mounting area, low-voltage leads a, b, c and o of the transformer body are respectively and electrically connected with one ends of the first conductive column, the second conductive column, the third conductive column and the fourth conductive column, the SW low-voltage switch, the PT protecting device and the kWh kilowatt-hour meter are arranged in the lower mounting area and are sequentially connected in series, the input ends a, b and c of the SW low-voltage switch are respectively and electrically connected with the other end of the first conductive column, low-voltage leading-out wires a, b and c of the kWh kilowatt-hour meter and a low-voltage leading-out wire o of the transformer body are respectively connected with an external cable by low-voltage wire outlets, the fixing device is arranged at the lower end of the lower mounting area, and the fixing device is provided with wire outlets which are communicated with the low-voltage wire outlets. The vertical column type transformer has the advantages that the development toward high altitude is realized, the land occupation area is greatly reduced, the environment-beautifying effect is realized, the operation and the maintenance are convenient, and the like.
