[0027] In this embodiment, by adjusting the position of the level-adjusting ventilation plate 3 on the fixed plate 2, after the ventilation window is fixed to the corresponding electrical equipment through the fixed plate 2, the level-adjusting ventilation plate 3 can be moved away from or close to the position where the vent is set on the electrical equipment. When the level-adjusting ventilation plate 3 is set in close proximity to the equipment, the protection level is determined by the ventilation plate 3 fitted on the equipment; when the level-adjusting ventilation plate 3 is set away from the equipment, the protection level is determined by the ventilation window on the original equipment, thereby realizing the adjustment of the protection level of the ventilation window.

[0028] A further technical solution is that there can be one or more level-adjusting ventilation plates 3 arranged on the fixed plate 2. The protection levels of the level-adjusting ventilation plates 3 are different, and the level-adjusting ventilation plates 3 arranged on the fixed plate 2 can be selected as needed; the protection level of the ventilation window is determined by the ventilation plates 3 fitted on the equipment casing.

[0029] Specifically, the level-adjusting ventilation plate 3 adjusts the protection level by setting the size of the ventilation holes, that is, when a plurality of level-adjusting ventilation plates 3 are set on a fixed plate 2, ventilation plates with different sizes of ventilation holes can be set.

[0030] In some embodiments, the structure of the fixing plate 2 is as follows: Figure 5 As shown, the fixing plate 2 can be set to a "J"-shaped structure, the fixing plate 2 includes a back plate, side plates vertically arranged at opposite ends of the back plate, and mounting surfaces 2-6 connected to the side plates, and guide grooves are arranged on the side plates of the fixing plate 2, and positioning grooves are arranged in the guide grooves, and the positioning grooves are used as fixing positions for the level adjustment ventilation plate 3;

[0031] Specifically, in this embodiment, a fixing position is set, and two guide grooves are set on one side of the fixing plate 2, including an upper guide groove 2-1 and a lower guide groove 2-2; a positioning groove is set in each guide groove, including an upper positioning groove 2-3 and a lower positioning groove 2-4.

[0032] Optionally, the upper positioning groove 2 - 3 and the lower positioning groove 2 - 4 are on the same vertical plane, and after the level-adjusting ventilation plate 3 is placed on the positioning groove, the level-adjusting ventilation plate 3 remains vertically placed.

[0033] In order to realize that the fixing plate 2 is detachably arranged on the door panel 1 of the device, a feasible implementation manner is that a through hole 2-5 is arranged on the mounting surface 2-6 of the fixing plate 2, and a connecting component is arranged through the through hole 2-5 to arrange the ventilation window of this embodiment at the ventilation port of the device, such as being arranged on the door panel 1;

[0034] Specifically, the connecting parts may be bolts, rivet screws 4 and the like.

[0035] Another feasible implementation method is to set a card slot adapted to the mounting surface 2-6 on the door panel 1 of the electrical equipment, and the mounting surface 2-6 is adapted to the size of the card slot; specifically, the opening of the card slot can face upward, and the mounting surface 2-6 slides into the card slot from above.

[0036] In some embodiments, the structure of the level-adjusting ventilation plate 3 is set as a flat plate, ventilation holes 3 - 4 of set sizes are set on the flat plate, and positioning guide plates are set on the flat plate corresponding to the fixed positions of the fixed plate 2 .

[0037] Specifically, the positioning guide piece can be of any shape and can be matched with the guide groove on the fixed plate 2 and the size of the fixed position. The match means that it can slide in the guide groove and can be stably set at the fixed position; the positioning guide piece can be rectangular, square, or the end of the positioning guide piece can be a thin piece in the shape of a triangle, a sphere, etc.

[0038] In this embodiment, two positioning guide pieces are respectively arranged at both ends of the fixing plate 2, including an upper positioning guide piece 3-1 and a lower positioning guide piece 3-2. The arrangement positions of the positioning guide pieces correspond to the positions of the guide grooves on the fixing plate 2.

[0039] A further technical solution is that a folded edge 3-3 is also provided on the level regulating ventilation plate 3, facing the inner concave surface of the fixed plate 2, and one surface of the folded edge 3-3 is opposite to the side plate of the fixed plate 2, so that after the level regulating ventilation plate 3 is set on the fixed plate 2, one surface of the folded edge 3-3 maintains a set gap with the side plate of the fixed plate 2.

[0040] In this embodiment, the level regulating ventilation plate 3 is provided with a folded edge 3-3 opposite to the side plate of the fixed plate 2, which increases the contact area through surface contact, can maintain the stability of the level regulating ventilation plate 3, and can prevent the level regulating ventilation plate 3 from falling off from the fixed plate 2.

[0041] Optionally, a flange 3 - 5 of a set width is extended upward from the upper end surface of the level-adjusting ventilation plate 3 , and after the level-adjusting ventilation plate 3 is fixed to the fixing plate 2 , the flange 3 - 5 exceeds the upper end surface of the fixing plate 2 .

[0042] When adjusting the protection level, pinching the flange 3-5 can facilitate the movement of the level adjustment ventilation plate 3.

[0043] Optionally, the level-adjusting ventilation plate 3 is further provided with fixing holes 3-6 for fixing it at the ventilation opening of the equipment.

[0044] The above-mentioned ventilation window is fixed on the electrical equipment to be installed, which can meet the ventilation requirements of a specific protection level. Figure 5 ) and protection level adjustment plate 3 ( Figure 6 ) are assembled together and fixed on the door panel 1 by means of pressure riveting screws 4, such as Figure 1 , Figure 2 shown.

[0045] The above-mentioned ventilation window can realize the protection level adjustment during use. Taking the setting of a fixed position and a protection level adjustment plate 3 in this embodiment as an example, the adjustment operation method is specifically described as follows:

[0046] 1) Place the anti-falling fold 3-3 of the protection level adjustment plate 3 toward the inner concave surface of the fixed plate 2, as shown in Figure 2 As shown;

[0047] 2) Slide the upper positioning guide piece 3-1 and the lower positioning guide piece 3-2 of the protection level adjustment plate 3 along the upper guide groove 2-1 and the lower guide groove 2-2 of the fixed plate 2, as shown in FIG. Figure 3 As shown;

[0048] 3) The upper positioning guide piece 3-1 and the lower positioning guide piece 3-2 of the protection level adjustment plate 3 slide into the interior of the fixed plate 2 along the upper guide groove 2-1 and the lower guide groove 2-2 of the fixed plate 2, and continue to slide until the upper positioning guide piece 3-1 and the lower positioning guide piece 3-2 of the protection level adjustment plate 3 fall into the upper positioning groove 2-3 and the lower positioning groove 2-4 of the fixed plate 2. At this time, the protection level adjustment plate 3 is in a fixed state. At this time, the protection level depends on the size of the ventilation window opening on the original equipment door panel 1, such as Figure 4 As shown;

[0049] 4) Lift the protection level adjustment plate 3, so that the upper positioning guide piece 3-1 and the lower positioning guide piece 3-2 of the protection level adjustment plate 3 are separated from the upper guide groove 2-1 and the lower guide groove 2-2 of the fixed plate 2, and the upper positioning guide piece 3-1 and the lower positioning guide piece 3-2 of the protection level adjustment plate 3 slide along the upper guide groove 2-1 and the lower guide groove 2-2 of the fixed plate 2 toward the door panel 1 until the protection level adjustment plate 3 and the door panel 1 are tightly attached together, and the pressure riveting studs 4 on the door panel 1 are inserted into the fixing holes of the protection level adjustment plate 3, and fixed with nuts. The protection level adjustment plate 3 is in a fixed state. At this time, the protection level depends on the size of the ventilation window opening on the protection level adjustment plate 3, such as Figure 1 shown.

[0050] Through the above steps, the protection level of the DC switchgear is adjusted.
