Abstract
The invention discloses a door structure of a metal-enclosed switchgear. The door structure is characterized by comprising a front lower door plate, the front lower door plate comprises a plate surface, an upper lateral side, a left lateral side, a right lateral side and a lower lateral side, the upper lateral side, the left lateral side, the right lateral side and the lower lateral side are arranged around the plate surface and connected with one another, a plurality of rectangular holes are formed in the lower lateral side along the transverse direction of the front lower door plate at intervals, an iron screen plate is arranged above the lower lateral side, and a plurality of rectangular holes are formed in the iron screen plate along the transverse direction of the front lower door plate at intervals and staggered with the rectangular holes in the lower lateral side of the front lower door plate. By the door structure, air incoming space is increased, surface dust accumulation is completely eliminated, compression resistance of the door plate is improved, and pressure and particulate matters do not rush out front the front, so that human injury is prevented. In addition, the rectangular holes in the iron screen plate and the rectangular holes in the lower lateral side of the front lower door plate are staggered with one another, so that particle ejection during internal arc burning is prevented effectively.
Description
Technical field
The present invention relates to field of electrical equipment, and in particular to a kind of door of metal enclosed switchgear.
Background technology
Metal enclosed switchgear is that all assemblings are completed and are enclosed in the metal shell of ground connection in addition to external connection
Switchgear.Shell is used as a part for metal enclosed switchgear, it is necessary to provide the degree of protection of regulation, to protect inside to set
Standby by ectocine, prevent personnel close to or touching live part, prevent personnel from touching motion parts.Meanwhile, in order to be able to make
Temperature rise inside metal enclosed switchgear reaches regulation requirement, it is necessary to be disposed with the structure of metal enclosed switchgear logical
Wind passage and vent, to play a part of ventilation, radiating.But the door with vent passages of routine institute as shown in Figure 1, Figure 2
Show, the oblong aperture that its vent 1 is opened up for 2 front of door-plate, the version of back side welding plane iron net plate 3, interior arcing test
When pressure and particulate matter easily break through iron net plate and spray from door front, it is impossible to effectively tested by arcing, the ferrum of vertical direction
Web plate equally also can collect dust, affect intake.
Metal enclosed switchgear is because the restriction of structure and overall dimensions, and its air intake passage needs to change air intake position,
So needing to redesign a kind of door so as on the premise of intake is increased, while being tested by arcing.
Content of the invention
The technical problem to be solved is that being put into aeration structure for existing metal enclosed switchgear is deposited
Deficiency and a kind of door of metal enclosed switchgear is provided, which solves the problems, such as the front lower storehouse intake of existing KYN28A,
Fan efficiency is improved, is more preferably tested by temperature rise, and when the arcing for avoiding is tested, pressure is gone out from front.
The technical problem to be solved can be achieved through the following technical solutions：
A kind of door of metal enclosed switchgear, including front lower door-plate, the front lower door-plate has a plate face and sets
Put in the plate face surrounding and interconnective upper side edge, left side, right edge and lower side, along described on the lower side
Being horizontally arranged at interval for front lower door-plate has some slots, the top of the lower side is provided with an iron net plate, described
There are some slots along being horizontally arranged at interval for the front lower door-plate on iron net plate, some slots on the iron net plate
Stagger each other a position with slot on lower side in the front lower door-plate.
In a preferred embodiment of the invention, the iron net plate is converted into step, a straight flange welding of step
On the inner surface of the plate face in the front lower door-plate, another straight flange is welded on lower side, and the horizontal edge of step is positioned at described
The top of the lower side in front lower door-plate, some slots on the iron net plate are arranged on the horizontal edge of step.
In a preferred embodiment of the invention, it is welded with the plate face inner surface of the front lower plate plate and surrounds frame-type
Upper reinforcement, left reinforcement, right reinforcement and lower reinforcement, positioned at the top of the iron net plate, institute on the lower reinforcement
State the left and right two ends of iron net plate and the left reinforcement, right reinforcement are welded to connect.
In a preferred embodiment of the invention, in the left side of the front lower door-plate, door lock is installed.
In a preferred embodiment of the invention, some hinges are provided with the right side edge of the front lower door-plate, if
Dry hinge is from top to bottom spaced.
Due to employing technical scheme as above, during ventilation, wind is entered by the slot on the lower side in front lower door-plate
Enter and entered in cabinet by some slots on iron net plate again, after Curve guide impeller, iron net plate is not placed directly against on door-plate and welds,
It is bent on the slot that step is covered on the lower side in front lower door-plate, the equal welded closure of surrounding meets cabinet IP4X will
Ask.Although air vent originally is many, it is 1mm to be close to door-plate and mesh size due to iron net plate, so that actual intake is become very
Little, and use time is long, and the web plate in front is equally understood collect dust and blocks mesh, and the effect of ventilation can be worse.Improvement sets
Air intake space is increased after meter, more prevents surface collect dust.Another new door front does not have air vent, and the crushing resistance of door-plate is more
Good, pressure will not be gone out from front with particulate matter, prevent from hurting sb.'s feelings.Some slots and the front lower door-plate on another iron net plate
In lower side on slot position mutually stagger, have when effectively prevent interior arcing granule spray.

Specific embodiment
Referring to Fig. 3 and Fig. 4, a kind of door of metal enclosed switchgear that in figure is given, including front lower door-plate 100,
Front lower door-plate 100 has a plate face 110 and is arranged on 110 surrounding of plate face and interconnective upper side edge 120, left side 130, the right side
Side 140 and lower side 150, have some slots 151 along being horizontally arranged at interval for front lower door-plate 100 on lower side 150.
Iron net plate 300 is converted into step, and a straight flange 310 of step is welded on the plate face 110 in front lower door-plate 100
On inner surface, another straight flange 320 is welded on lower side 150, and the horizontal edge 330 of step is located at the downside in front lower door-plate 100
