Ground mounting type transformer device

Abstract

The present invention provides a ground mounting type transformer device. The ground mounting type transformer device comprises first and second louver units (21, 22) which are provided with blades (26, 42) obliquely protruding from surfaces towards back sides at inner sides of air vents (25, 41), and the blades of the first louver unit and the blades of the second louver unit are opposite to each other, so as to form louvers (20). The blades (26, 42) of the first louver unit and the second louver unit are staggered relatively in a vertical direction, so that each gap (G) between the adjacent blades (26, 26) of the first louver unit (21) is shielded by the blade (42) of the second louver unit (22), thus a device contained in an outer box (10) can not be touched. Therefore, the ground mounting type transformer device provided with the louvers in vents of the outer box can prevent a foreign body from being inserted into the outer box through the gap between the blades of the louver.

Description

technical field [0001] The present invention relates to a ground installation type transformer device installed on a sidewalk or the like. Background technique [0002] The ground-mounted transformer device has a structure in which electrical equipment including a power distribution transformer is accommodated in an outer box, and is usually installed on the side of a sidewalk or the like. The transformer housed in the outer case generates heat as it operates, so the outer wall of the outer case is provided with a ventilation port for discharging the hot air in the outer case to the outside and allowing the cold air from the outside to flow into the outer case. In order to prevent passers-by from passing their hands through the ventilation opening and touching the equipment in the outer box or causing foreign objects to pass through the ventilation opening and inserting into the outer box, shutters (also called skylights) are installed on the ventilation opening.

AI Technical Summary

Problems solved by technology

[0010] Figure 9 The louver 1' shown has a structure in which a plurality of mountain-shaped blades 4' are arranged up and down and connected together, so not only does it take time to manufacture the blades, but the structure of the louver also becomes complicated.

In addition, in order to connect the gable blade 4' and the connecting member 6 together, welding is required, so it takes time to manufacture the louver, and its manufacturing cost cannot be avoided.
