Description

Transformer substation's dc-to-ac converter ventilation window

Technical Field

The utility model relates to an electric power equipment technical field, especially a transformer substation's dc-to-ac converter ventilation window.

Background

Inverter wide application among the prior art is in power equipment, and the inverter is generally installed in the box, in order to make the inverter use safe and reliable more, the inverter is provided forced air-cooling by inside fan, and cold wind gets into the inverter inside through preceding air grid to through the air grid discharge hot-blast on inverter upper portion, avoid the inverter temperature to increase, ventilation window among the prior art generally uses the shutter, and just so leads to inside the rainwater infiltration box easily, thereby has certain potential safety hazard.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned condition, for overcoming prior art's defect, the utility model provides a transformer substation's dc-to-ac converter ventilation window, effectual solved current ventilation window rain-proof effect not good, there is the problem of potential safety hazard.

The technical scheme for solving the problem is that the rain sheltering window comprises a window frame, wherein a plurality of V-shaped rain sheltering units which are uniformly distributed up and down and have downward openings are arranged in the window frame; the rain shielding unit comprises a V-shaped plate with a downward opening, the front end of the section of the plate is downward inclined, a first vertical plate along the length direction of the plate is fixed on the upper side of the rear end of the plate, a first inclined plate along the length direction of the first vertical plate is arranged on the front side of the upper end of the first vertical plate, the first inclined plate is parallel to the plate, a second vertical plate along the length direction of the plate is arranged on the lower side of the front end of the plate, a second inclined plate parallel to the plate is arranged on the right side of the lower end of the second vertical plate, and the longitudinal section of the rain shielding unit is S-; the units are uniformly distributed from top to bottom, wherein a first inclined plate in the lower rain shielding unit is arranged between a plate and a second inclined plate in the upper rain shielding unit.

The utility model discloses the structure is ingenious, and inside the effectual rainwater of having avoided entering into the dc-to-ac converter, the security performance of improvement dc-to-ac converter, simple structure makes easily, easily promotes.

Detailed Description

The following detailed description of embodiments of the present invention is made with reference to the accompanying drawings.

As shown in fig. 1 to 4, the rain sheltering window comprises a window frame 1, wherein a plurality of V-shaped rain sheltering units which are uniformly distributed up and down and have downward openings are arranged in the window frame 1; the rain shielding unit comprises a V-shaped plate 2 with a downward opening, the front end of the section of the plate is downward inclined, a first vertical plate 3 along the length direction is fixed on the upper side of the rear end of the plate, a first inclined plate 4 along the length direction is arranged on the front side of the upper end of the first vertical plate 3, the first inclined plate 4 is parallel to the plate, a second vertical plate 5 along the length direction is arranged on the lower side of the front end of the plate, a second inclined plate 6 parallel to the plate is arranged on the right side of the lower end of the second vertical plate 5, and the longitudinal section of the rain shielding unit is S-shaped; the units are uniformly distributed from top to bottom, wherein the first inclined plate 4 in the lower rain shielding unit is arranged between the plate in the upper rain shielding unit and the second inclined plate 6.

In order to discharge the collected rainwater, the section of the window frame 1 is U-shaped, the upper side plate and the lower side plate of the window frame 1 are in a V-shaped structure with a downward opening, the end parts of the rain shielding units are fixed in the left side plate and the right side plate of the window frame 1, and the lowest end of the window frame 1 is provided with a through hole 7.

In order to achieve better rainproof and dustproof effects, the front end of the window frame 1 is covered with a filter screen.

It is worth noting that in two adjacent rain sheltering units, the lower first inclined plate 4 is arranged between the second inclined plate 6 in the upper rain sheltering unit and the plate, and a channel is formed, and cold air can enter the box body from the channel.

During the use, will the utility model discloses fix on the transformer substation's dc-to-ac converter box to at the fixed fan of the correct installation in suitable position, during rainy, the rainwater flows forward in the box outside along a plurality of panels, and another part rainwater moves and collects at the frame lower extreme to panel to both sides along, and flows out by through-hole 7, because the passageway is the zigzag form, so cold wind can not bring into the rainwater in getting into the box.

The utility model discloses during well air inlet, cold wind need be through a tortuous passageway to the passageway presents the slope downwards on the whole, even there is partial rainwater entering channel, can not get into in the box yet, has improved the security and the reliability of dc-to-ac converter work.
