Description
Technical field
The utility model relates to ring main unit, particularly relates to a kind of ring main unit sand-proof structure.
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.
When existing ring main unit is positioned over wind-force larger area, needs are fixed, prevent from being arrived by wind, but the lower wall of existing ring main unit is only fixed by screw, when running into loose regional of geology, shorter screw is fixing very unreliable, grip very little, makes ring main unit often be blown to, causes power breakdown, have influence on regional power supply, the dust storm in a lot of area is comparatively large, and sandstone strikes on cabinet for a long time, easily destroys cabinet, destroy the sealing of ring main unit after puncturing cabinet, cause ring main unit to leak electricity.
Utility model content
The purpose of this utility model is the shortcoming and defect overcoming above-mentioned prior art, provides a kind of ring main unit sand-proof structure, solves existing ring main unit when often sending out area for dust storm, cabinet insufficient strength, after being impacted by sandstone for a long time, and easily breakdown defect.
The utility model is achieved through the following technical solutions: ring main unit sand-proof structure, 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.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.
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: the lateral layout of ring main unit is become semicircle groove and semicircle raised line interval, in a kind of sinusoidal fluctuating shape, when making dust storm blow to cabinet, because this arc, make sandstone be difficult to frontal impact on cabinet, protect cabinet.
