Abstract
A kind of solid insulation ring main unit with blast resistance construction, relate to the pressure relief device in a kind of solid insulation ring main unit, comprise cabinet and be arranged on the Switch main body in cabinet, Switch main body has the housing of a closed epoxy resin material, switch element is provided with in housing, be provided with venting on the housing, the wall thickness of the housing of venting region is 2 ~ 3mm, housing remainder thickness is 12 ~ 13 mm, break when enclosure interior pressure reaches 0.15Mpa to enable this venting, pressure release passage is provided with in described cabinet, one end of pressure release passage is docked with described venting, the other end stretches out outside cabinet.The energy of looped network cabinet switch inside can discharge along specific blast resistance construction by the utility model, effectively ensures the fail safe of switch, and the personal safety of site operation personnel.
Description
Technical field
The utility model relates to the design of pressure relief device in solid insulation ring main unit, is specifically related to a kind of solid insulation ring main unit with blast resistance construction.
Background technology
In 10KV solid insulation ring main unit, switch primary circuit is all closed in the housing by poured with epoxy resin, in switch running, there is the switch internal arcing because the reasons such as misoperation or the failure of interruption of switch own cause sometimes, inner arcing can go out huge energy in abrupt release, housing is caused to burst, if the blast resistance construction of the composition such as the pressure relief device of now in advance setting and pressure release passage, just easily there is and that cause personnel casualty accidents indefinite due to explosion energy release direction.
Utility model content
Problem to be solved in the utility model is: when switch generation arcing fault, energy can be discharged along specific blast resistance construction, thus avoid causing larger security incident.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of solid insulation ring main unit with blast resistance construction, comprise cabinet and be arranged on the Switch main body in cabinet, Switch main body has the housing of a closed epoxy resin material, switch element is provided with in housing, be provided with venting on the housing, the wall thickness of the housing of venting region is 2 ~ 3mm, housing remainder thickness is 12 ~ 13 mm, break when enclosure interior pressure reaches 0.15Mpa to enable this venting, pressure release passage is provided with in described cabinet, one end of pressure release passage is docked with described venting, the other end stretches out outside cabinet.
Beneficial effect: the utility model arranges the venting structure of local weak on the housing of Switch main body; and the pressure release passage docked with venting is set in ring network cabinet body; thus ensure when switch generation arcing fault; venting thin-walled on housing breaks; from venting release arcing energy; and by pressure release passage, arcing energy is drained into cabinet outside, effectively can ensure the fail safe of switch, the personal safety of available protecting site operation personnel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Be labeled as in figure: 1, cabinet, 11, pressure release passage, 2, Switch main body, 21, housing, 22, venting.
Embodiment
As shown in Figure 1, a kind of solid insulation ring main unit with blast resistance construction, the Switch main body 2 comprising cabinet 1 and be arranged in cabinet 1, Switch main body 2 has a closed housing 21, housing 21 is formed by poured with epoxy resin, switch element is provided with in housing 21, described housing 21 is provided with venting 22, venting 22 is positioned at the rear portion of housing 21, the wall thickness of the housing 21 of venting 22 region is less than the thickness of housing 21 remainder, to form local weak structure at venting 22 place of housing 21, for discharging arcing energy, pressure release passage 11 is provided with in described cabinet 1, one end of pressure release passage 11 is docked with described venting 22, the other end stretches out outside cabinet 1, pressure release passage 11 is arranged on after cabinet 1 accordingly, the normal running of ring main unit can not be affected.Cabinet 1 is provided with the opening passed through for pressure release passage 11, pressure release passage 11 is made to stretch out outside cabinet 1, when switch internal generation arcing fault, the energy produced can make venting 22 break, thus energy can be discharged in Switch main body 2 by venting 22, and be discharged into the assigned address of cabinet 1 outside along the pressure release passage 11 docked with venting 22, thus avoid causing larger security incident.Further, the diameter of described venting 22 is 75 ~ 80 mm, and the wall thickness of the housing 21 of venting 22 region is 2 ~ 3mm, housing 21 remainder thickness is 12 ~ 13 mm, in order to ensure that venting 22 breaks when reaching about 0.15Mpa at housing 21 internal pressure, release arcing energy.
