Abstract
A kind of ring main unit with switch visual fracture structure, relate to the visual fracture structure of 10kV looped network cabinet switch equipment, comprise the Switch main body being arranged on cabinet inside, Switch main body comprises a closed housing and is arranged on the switch element of enclosure interior, be provided with the observation window for observing station state residing for switch element on the housing, LED is provided with in the inside of described housing, housing is provided with the button opened for controlling this LED and close, housing is also provided with the venting of local weak structure, 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.Station state residing for switch reality can present by the utility model effectively, ensure that the definitely reliable of the on-the-spot switch fracture of equipment use or earthing position information, improves the fail safe of equipment operating.
Description
Technical field
The utility model relates to the visual fracture structure of 10kV looped network cabinet switch equipment, is specifically related to a kind of ring main unit with switch visual fracture structure.
Background technology
In looped network cabinet switch equipment, position of the switch instruction, concerning most important user, is that user is at the scene to the foundation that on off state judges.Existing common structure is by mechanism driving, indirectly position of the switch state is shown on panel.But sometimes due to reasons such as mechanism's clamping stagnation, transmission failure, the position of the switch can be caused to indicate and not to be inconsistent with switch virtual condition, serious potential safety hazard will be brought like this.
Utility model content
The problem may be inconsistent with switch virtual condition that position of the switch state exists is presented for existing looped network cabinet switch position instruction employing machine driving, Display panel, a kind of safe and reliable switch visual fracture structure of the utility model design, for in solid insulation ring main unit switchgear, to improve equipment operating fail safe.
For achieving the above object, the technical solution of the utility model is: a kind of ring main unit with switch visual fracture structure, comprise the Switch main body being arranged on cabinet inside, Switch main body comprises a closed housing and is arranged on the switch element of enclosure interior, be provided with the observation window for observing station state residing for switch element on the housing, the position at observation window place is corresponding with the switch fracture of described switch element or ground connection station position, in the inside of described housing, switch fracture or the ground connection station position place of switch element are provided with LED, housing is provided with the button opened for controlling this LED and close.
Further, 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, be provided with pressure release passage in described cabinet, one end of pressure release passage is docked with described venting, and the other end stretches out outside cabinet.
Beneficial effect: the utility model is by being arranged on the observation window on Switch main body housing, and be arranged on the LED of enclosure interior, station state residing for switch reality can be presented effectively, ensure that the definitely reliable of the on-the-spot switch fracture of equipment use or earthing position information, improve the fail safe of equipment operating.
The venting structure of local weak is set at the housing rear portion of Switch main body; and the pressure release passage docked with venting is set in ring network cabinet body; can ensure when switch generation arcing fault; arcing energy can effectively drain into cabinet outside; 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, 23, observation window, 24, LED.
Embodiment
As shown in Figure 1, a kind of ring main unit with switch visual fracture structure, comprise cabinet 1 and the Switch main body 2 being arranged on cabinet 1 inside, Switch main body 2 comprises a closed housing 21 and is arranged on the switch element of housing 21 inside, described housing 21 is provided with the observation window 23 for observing station state residing for switch element, the position at observation window 23 place is corresponding with the switch fracture of described switch element or ground connection station position, observation window 23 is arranged on before housing 21, be convenient to observe, in the inside of described housing 21, switch fracture or the ground connection station position place of switch element are provided with LED 24, housing 21 is provided with the button opened for controlling this LED 24 and close.The observation window 23 arranged by housing 21 and LED 24 clearly can observe the station state residing for Switch main body 2 internal switch element, avoid because existing machinery mode presents the safety problem that switch fracture or ground state and actual conditions be not inconsistent and cause.
Described housing 21 is provided with venting 22, housing 21 is formed by poured with epoxy resin, 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, can not affect the normal running of ring main unit.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 housing 21 internal pressure reaches about 0.15Mpa, release arcing energy.
