Abstract
The utility model discloses a safety guardrail of a gas insulated metal-enclosed switchgear. The safety guardrail of the gas insulated metal-enclosed switchgear solves the problem that a safety rail of an existing geographic information system (GIS) device is cut off at the position of a bus tube, a closed overhaul area cannot be defined, and potential safety hazards exist. The safety guardrail comprises a three-legged base (5), a lower-section rail bar (4) in the vertically perpendicular direction is fixedly arranged on the three-legged base (5), the lower-section rail bar (4) is a hollow tube, an upper-section rail bar (2) is movably sleeved in the lower-section rail bar (4), the upper-section rail bar (2) is a hollow tube, a hazard warning indicating lamp (1) is fixedly arranged at the top end of the upper-section rail bar (2), an inner fastener is arranged on the side wall of the lower-section rail bar (4), a safety fence (3) capable of winding automatically is arranged in the upper-section rail bar (2), and expansion joints of the safety fence (3) are both arranged on the side wall of the upper-section rail bar (2) and the side wall of the lower-section rail bar (4). The safety guardrail of the gas insulated metal-enclosed switchgear is particularly suitable for safety enclosure of the GIS device.
Description
Technical field
The utility model relates to a kind of safe fence, particularly a kind of safe fence for GIS equipment, and this fence can effectively be isolated operational outfit and repair apparatus, effectively prevents maintainer's mistakenly entering charged chamber.
Background technology
The full name of GIS equipment is " Cubicle Gas-Insulated Switchgear ", GIS equipment is all to be enclosed in a series of parts such as line breaker, isolating switch, grounding switch, bus in metal can, section is filled with the SF6 insulating gas of certain pressure within it, therefore also claim " SF6 fully closed combined electric unit ".The advantage that GIS equipment is compared with conventional open type equipment maximum is compact conformation, and floor space is little, and is simultaneously easy to maintenance.But because the bus integral installation of GIS equipment is in bus bar canister, and be the installation that is close to the ground, so just cause conventional safe fence can be cut off at the bus bar canister place, can not surround the maintenance zone of sealing, strengthened the possibility of maintainer's mistakenly entering charged chamber.So just be badly in need of a kind of special safe fence for GIS equipment of exploitation.
Summary of the invention
The utility model provides a kind of safety barrier of Cubicle Gas-Insulated Switchgear, and the safe fence that has solved existing GIS equipment can be cut off at the bus bar canister place, and there is the problem of potential safety hazard in the maintenance zone that can not surround sealing.
The utility model is to solve by the following technical programs above technical problem:
a kind of safety barrier of Cubicle Gas-Insulated Switchgear, comprise three leg bases, be fixedly installed the lower joint rail bar of up and down vertical direction on three leg bases, lower joint rail bar is hollow section, movable sleeve is connected to and saves rail bar in lower joint rail bar, upper joint rail bar is hollow section, be fixedly installed the danger warning warning light on the top of upper joint rail bar, be provided with interior buckle on the sidewall of lower joint rail bar, be provided with the safe purse seine that automatically rolls tightly in upper joint rail bar, be provided with the shrinkage joint of safe purse seine on the sidewall of the upper and lower joint rail bar of the sidewall of upper joint rail bar.
Three legs of described three leg bases are telescopic leg.
The utility model is by telescopic upper joint rail bar, increase the layout height of safe fence, can stride across above the bus bar canister of GIS, solved the problem that safe fence is cut off, can form the safe fence of continuous sealing when maintenance, guarantee the safety the when maintainer works.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
a kind of safety barrier of Cubicle Gas-Insulated Switchgear, comprise three leg bases 5, be fixedly installed the lower joint rail bar 4 of up and down vertical direction on three leg bases 5, lower joint rail bar 4 is hollow section, movable sleeve is connected to joint rail bar 2 in lower joint rail bar 4, upper joint rail bar 2 is hollow section, be fixedly installed danger warning warning light 1 on the top of upper joint rail bar 2, be provided with interior buckle on the sidewall of lower joint rail bar 4, be provided with the safe purse seine 3 that automatically rolls tightly in upper joint rail bar 2, be provided with the shrinkage joint of safe purse seine 3 on the sidewall of the upper and lower joint rail bar 4 of the sidewall of upper joint rail bar 2.
Three legs of described three leg bases 5 are telescopic leg.
Danger warning warning light 1 is fixed on the top of rail bar, and when the maintainer was close, light began to glimmer and send alarm sound.Upper joint rail bar 2 can be withdrawn into when depositing in lower joint rail bar 4, can be from the interior extraction of lower joint rail bar 4 during use, and in adopting, buckle is fixed on lower joint rail bar 4, prevents from automatically retracting in lower joint rail bar 4.Be provided with the shrinkage joint of safe purse seine 3 on the sidewall of the upper and lower joint rail bar 4 of the sidewall of upper joint rail bar 2, safe purse seine 3 can be withdrawn in joint rail bar 2 when depositing, can be from the interior extraction of upper joint rail bar 2 during use.Lower joint rail bar 4 is fixed on base 5, supports and deposit joint rail bar 2.The fixing whole fence that can firmly land when the tripod of three leg bases 5 struts, and tripod can close up to regain and be convenient to deposit, and can strut convenient the placement during use.Hook 6 is fixed on each up and down of lower joint rail bar 4, is used for articulating conventional safe fence.
Claims (2)
1. the safety barrier of a Cubicle Gas-Insulated Switchgear, comprise three leg bases (5), be fixedly installed the lower joint rail bar (4) of up and down vertical direction on three leg bases (5), it is characterized in that, lower joint rail bar (4) is hollow section, movable sleeve is connected to upper joint rail bar (2) in lower joint rail bar (4), upper joint rail bar (2) is hollow section, be fixedly installed danger warning warning light (1) on the top of upper joint rail bar (2), be provided with interior buckle on the sidewall of lower joint rail bar (4), be provided with the safe purse seine (3) that automatically rolls tightly in upper joint rail bar (2), be provided with the shrinkage joint of safe purse seine (3) on the sidewall of the upper and lower joint rail bar of the sidewall of upper joint rail bar (2) (4).
