Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of making to form the convection current air in the cable vault to play the high-tension switch cabinet of thermolysis.
The purpose of this utility model realizes by following technical solution:
A kind of high-tension switch cabinet, comprise by top board, the cabinet that base plate and outer panel surround, described cabinet inside is become to be positioned at control room and the handcart chamber of cabinet front side by baffle for separating, be positioned at bus-bar room and the cable vault of cabinet rear side, be provided with dry-type transformer in the described cable vault, it is characterized in that: described cabinet top board offers the relief hole that communicates with described cable vault, be provided with the decompression cover of buckle closure on described relief hole on the described cabinet top board, described decompression cover top offers some first louvres of up/down perforation, be provided with the first mesh plate of described the first louvre of capping on the described decompression cover, be provided with the horizontal dust board that is suspended to the first louvre below by vertical connecting on the described decompression cover, offer some the second louvres that communicate with described cable vault on the described cabinet base plate, be provided with the second mesh plate of described the second louvre of capping on the described bottom of cabinet bulk.
Further, be provided with in the described cable vault be used to the blower fan that air is flowed from described the second louvre to described the first louvre.
Further, described blower fan is arranged at described dry-type transformer downside, and wind direction is the 40-50 ° of inclination that make progress towards described dry-type transformer.
Further, described relief hole is elongated hole, described decompression cover is the rectangle box body that bottom opening and two bottom sides are formed with two horizontal flanks, the horizontal flank of one side of described decompression cover is connected with described cabinet top board by metal bolts, the horizontal flank of opposite side is connected with described cabinet top board by nylon bolt, and described the first mesh plate and dust board are arranged in described long rectangular box.
Further, described dust board periphery is formed with upwardly extending periphery edge.
Further, described first, second louvre is the elongated hole of equidistantly arranging.
Further, the mesh aperture of described first, second mesh plate is 0.8-1mm.
The utlity model has following beneficial effect:
When equipment moves, the dry-type transformer heating, hot air rising is to decompression cover, and outside the first louvre was discharged cabinet, cold air flow in the cabinet from the second louvre simultaneously, so just formed good convection current in cabinet, effectively heat in the cabinet was discharged outside the cabinet; If the dry-type transformer capacity is large, caloric value is large, also can install blower fan additional at the dry-type transformer downside, strengthens radiating effect; Top board and base plate at cabinet arrange first, second mesh plate, and mesh aperture is 0.8-1mm, can guarantee that like this switch cubicle reaches required degree of protection, at decompression cover dust board is set in addition and can prevents that dust from affecting equipment in the cabinet, the dust board periphery is formed with upwardly extending periphery edge, can improve the contaminant holding capacity of dust board; First, second louvre also can release partial pressure when device fails in addition.
