Abstract
A sealing box body of a switch cabinet comprises a front sealing plate, lateral sealing plates and a back sealing plate which are in split joint. Sealing glue is filled in gaps between the sealing plates. The front sealing plate is provided with a rotating shaft hole, and a sealing ring is arranged on the periphery of the rotating shaft hole. The box body of the switch cabinet is a frame structure formed by steel plates, and the sealing box body is formed by applying a fixed seal and a movable seal in combination mode. The fixed seal of the box body is formed by filling the long-acting sealing glue special for sheet metal box plates, and the movable seal of the box body is formed by jointing the rotating shaft hole with a sealing ring in split mode. Therefore, air cannot enter the inside of the box body through the gaps on the box body and the operation rotating shaft hole. In addition, a natural ventilation channel groove is arranged in the box body to enable electronic components inside the box body can be ventilated and conducted on heat dissipation. Simultaneously, an air cleaning device is installed at the position of an inlet of a ventilation hole to ensure that clean air enters the cabinet and lower temperature in the cabinet. Further, the sealing box body ensures that the cabinet is clean, and the effect that insulation strength in the cabinet decreases during long-time operation can be reduced.
Description
Technical field
The utility model relates to a kind of switch cubicle casing, particularly a kind of enclosed switch cabinet casing.
Background technology
The frame structure that Chinese patent document number CN1048300 discloses a sealed switchgear cabinet on January 2nd, 1991 is to be made up of frame unit identical and that process angle-shaped piece, and the edge of angle-shaped piece is that bending is rectangular to form folded end.Yet the arris of angle-shaped piece is bonded to each other by diagonal (hypotenuse) seal, and the sealing part provides the sealing device between two switch cubicle flat boards and formed the dihedral connection.Dull and stereotyped and bending arris is installed on the frame unit by part.The switchgear cabinet of this structure is not in fact a hermetically-sealed construction, and reason is that the junction of each face exists the slit, and dust can see through these slits and enter in the switch cubicle, influences the heat radiation of switch cubicle internal electric element and the fail safe of use.In addition; The switch cubicle of similar said structure; Generally need to install the natural ventilation lane device, guaranteeing ventilation and heat in the cabinet, but because a large amount of impurity such as the dusts of carrying under one's arms in the cabinet outer air; Can influence the effect of heat radiation when impurity gets in the cabinet in this air, the long-term use reduced the dielectric strength between the electric component in the cabinet.
The utility model content
The purpose of the utility model aims to provide the enclosed switch cabinet casing of a kind of simple and reasonable, good sealing effect, heat radiation and high safety, to overcome weak point of the prior art.
By a kind of enclosed switch cabinet casing of this purpose design, comprise preceding shrouding, side seal board and the back shrouding of mutual splicing; Its architectural feature is that seam is filled out envelope fluid sealant arranged between each shrouding, to form the static seal of casing.
Shrouding is by same block plate bending forming before said, it comprise front, end face and below.The front of shrouding and/or end face and/or following both sides are provided with bending minor face or dihedral plate before said, and bending minor face or dihedral plate are right after fixing through the side seal board of closed type rivet or the self-tapping screw and the switch cubicle casing left and right sides.Said back shrouding periphery is provided with the end face of bending minor face or dihedral plate and side seal board, preceding shrouding and followingly is right after fixing through closed type rivet or self-tapping screw.
Shrouding is provided with rotational axis hole before said, and the rotational axis hole periphery is provided with sealing ring, to form the movable sealing of casing.
Be provided with natural ventilation channel slot, air-vent outlet and air-vent import in the said switch cubicle casing; The natural ventilation channel slot is arranged between the air-vent import and export, and air-vent import department is provided with aircleaning facility.
Said aircleaning facility comprises filter cotton, and filter cotton passes through frame fixation in the air-vent import outside; The framework surface is provided with some through holes.
Said natural ventilation channel slot is arranged on switch cubicle casing inner bottom part rear side.
The switch cubicle casing of the utility model is one and constitutes frame structure by steel plate; Fill out the movable sealing that sealing seam forms the static seal and the sealing ring concatenation rotational axis hole formation casing of casing in conjunction with using panel beating boxboard long-acting special fluid sealant; Thereby constitute the seal case of switch cubicle, guarantee that air does not enter into box house from casing seam and operation rotational axis hole.In addition, can ventilation and heat for making the box house electric component, in casing, be provided with the natural ventilation channel slot, simultaneously aircleaning facility is installed by air-vent import department, air clean to guarantee, cleaning gets in the cabinet, plays the effect that reduces in-cabinet temperature; Simultaneously, guarantee that cabinet is interior clean, the reduction of dielectric strength in the cabinet during the minimizing long-time running.It is simple and reasonable, good sealing effect, tool natural heat dissipation function and high safety.
