Description
Technical field
The utility model relates to ring main unit, particularly relates to a kind of sand prevention pressure release type ring main unit.
Background technology
Outdoor ring main unit adopt vacuum switch as breaking device, SF6 gas common box type insulate, compact conformation, floor space is little, good looking appearance, can with surrounding environment cooperation.Owing to have employed hermetically sealed, all insulation theory, all switch sections in RVAC ring main unit, are sealed in main box completely containing all high-voltage charged bodies and mechanism section, do not affect by condensation and extraneous filthy environment; Main box degree of protection can reach IP67, is equipped with the tangible cable end of Cusparia water proof type, effectively can defend the sporadic flood infringement in the multiple district of rainwater.
Existing ring main unit is generally sealing, generally needing, relief valve is set and carries out pressure release, prevent internal pressure excessive, damage electronic device, relief valve is connected to outer end by a relief hole, only when cabinet internal pressure is excessive, relief hole is just communicated with in cabinet by relief valve, carries out pressure release, connection is cut off again after pressure release completes, but the existing ring main unit being positioned at dust storm large regions, because dust storm is excessive, often causes relief hole to block.
Utility model content
The purpose of this utility model is the shortcoming and defect overcoming above-mentioned prior art, provides a kind of sand prevention pressure release type ring main unit, solves existing ring main unit when being positioned at dust storm area, often occurs the defect that relief hole blocks.
The utility model is achieved through the following technical solutions: sand prevention pressure release type ring main unit, comprise cabinet and four mounting rods, the corner, lower end of described cabinet is respectively arranged with a connecting rod, connecting rod one end is movably attached to cabinet, the other end is provided with the collar, described mounting rod comprises straight-bar, straight-bar one end is most advanced and sophisticated, the other end is the end of thread, on straight-bar, close most advanced and sophisticated place is around being provided with helical-blade, and end of thread place is provided with baffle ring, the internal diameter of the collar and the diametric fit of straight-bar, the side of described cabinet is furnished with spaced half slot, semicircle raised line is provided with between adjacent half slot, described half slot and semicircle tab parallel, the radius of described half slot is consistent with the radius of semicircle raised line, spacing between adjacent half slot is consistent with the diameter of half slot, cabinet is enclosed construction, its upper end is provided with a relief valve, relief valve connects outer end by relief hole, pressure relief vent external port place is provided with a protective cover, protective cover is hollow hemisphere shape, protective cover is rotatably mounted on cabinet, its top is provided with a wind direction board, wind direction board in the form of sheets, be fixed on vertically on protective cover, the side of protective cover is provided with a through hole, through hole is positioned at the side of wind direction board.When this device is installed, first measure distance, four mounting rods are positioned over ring main unit surrounding, surround a quadrangle, the quadrangle that when size of this quadrangle is put down with cabinet upper connecting rod, four collars are linked to be is consistent, four mounting rods are squeezed in ground, mainly enter underground by spiral, because there is helical-blade, enter very light, after entering ground, reservation baffle ring and the end of thread are in upper end, at this moment connecting rod is put down, the collar just in time puts the end of thread, be placed on baffle ring, then the end of thread to be screwed on nut, ensure that the collar does not depart from, at this moment fix by ring main unit, because helical-blade is in the stop of vertical plane, ensure that mounting rod is difficult to directly be extracted, so wind is difficult to blow ring main unit.The cabinet surface of this device is provided with half slot alternately and semicircle raised line, half slot is a cross section is semicircular groove, semicircle raised line is a cross section is the bar of semicircle, both on cabinet alternately, by cabinet cutting perpendicularly, cabinet outer end forms sinusoidal line, when dust storm blows to cabinet, after sandstone bumps against cambered surface, circumferential power can be produced, sandstone is moved to the lowest point, because both sides have sandstone to move to the lowest point, make sandstone in the lowest point collision accumulation, follow-up sandstone clashes into because these collect the sandstone buffering stayed, to the thinner the lowest point place impulsive force of cabinet very little, thus protect cabinet, the sandstone of accumulation can drop because of gravity, but because constantly have new sandstone, very good to the protection of cabinet, and wind is offset because this lowest point is clashed into, also very little to the dynamics of blowing of cabinet, ensure that the effect of the anti-blown sand of cabinet well.Arrange a protective cover outside the relief hole of this device, protective cover is hemispherical, and it covers on relief hole, protective cover rotates to be installed, and top is sheet wind direction board, when wind is moved, wind direction board is just as wind vane, make bearing of trend consistent with wind direction, just make the protective cover of below rotate, through hole is positioned at protective cover side, and be positioned at the side of wind direction board, namely at this moment through hole aperture is being just vertical with wind direction to direction, namely makes that dust storm is rare can enter protective cover, blocks relief hole.
Further, the bottom of above-mentioned protective cover is circumferential edge, and circumferential edge is provided with spin, facilitates protective cover to rotate.
Further, be provided with anchor ear directly over above-mentioned connecting rod and cabinet junction, the internal diameter of anchor ear coordinates with connecting rod, and anchor ear comprises two semi-rings, and one of them semi-ring is fixed on cabinet.Anchor ear is used for the fixing of connecting rod, and mainly ring main unit is when mobile, and connecting rod meeting whipping, being in the way very, being unfavorable for the carrying of device, so arrange anchor ear, being fixed by connecting rod, facilitate carrying.
Further, the two ends of above-mentioned semi-ring is all provided with connector, and connector is provided with screwed hole.
Further, above-mentioned anchor ear is less than the length of connecting rod to the distance of connecting rod and cabinet junction, ensure that connecting rod can be fixed by anchor ear.
The beneficial effects of the utility model are: by a protective cover in the relief hole upper cover of ring main unit, protective cover is arranged a wind direction board, make the through hole on protective cover and wind direction forever vertical, not to windward, make blown sand be difficult to through hole on protective cover and enter protective cover, eliminate the possibility that relief hole is blocked.
