Description
Technical field
This utility model is related to air switch technical field and in particular to a kind of air switch safety device.
Background technology
Regulation according to 6.5.1 in the new safety of GB (gb 26860-2011): " getting final product power transmission to work once closing a floodgate
' No switching on, someone's work on the isolator operation handle in place, should be hung！' or ' No switching on, circuit someone works！’
Nameplate ", therefore in some power failure work, air switch need to disconnect and arrange corresponding nameplate.In (the change of current of existing transformer station
Stand) safety measure arrangement in, " No switching on, someone work " aluminum nameplate of 15cm*15cm is usually used, in nameplate
Hung using bonnet cotton or nylon wire after two jiaos of punchings about upper end.
The program has several places drawback: one, aluminum nameplate is metal material, has electric conductivity, and air switch is most
Positioned at front and the back side of various terminal boxs, mechanism case or secondary screen cabinet, joint wiring is more, if having wind or working principle
Produce rocks and falls, and easily causes short circuit and leads to device damage or tripping operation；2nd, more narrow more than the infield of air switch
Narrow, and air switch surface and its fixing equipment surface are typically more smooth, if hanging traditional nameplate in size and suspension
Larger difficulty is had on mode；Even if three pass through rope can air switch or around hung on casing, also hold
Easily cause to block when observing air switch position, also can produce simultaneously and malfunction is occurred to this air switch or neighbouring air switch
The risk made.
Therefore, design that a kind of new air switch safety device is a need for so as to can be based on rigidly executing
The regulation of the new safety of GB, can solve the problem that again difficulty that three above problem brought with risk it is adaptable to each electric pressure becomes
Power station (current conversion station) single-phase, two-phase and three-phase air switch.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of safe and reliable, easy accessibility
Air switch safety device.
For realizing object above, the technical solution adopted in the utility model is:
A kind of air switch safety device, is used for being clamped in air switch boss, including two intermediate plates, with two intermediate plates
The catch being connected as a single entity with side, the distance inside described two intermediate plates be gradually reduced from catch is to the direction away from catch from
And forming resilient clamp portion, the distance of described resilient clamp portion is less than the width of air switch boss, the length of described two intermediate plates
Degree is matched with the length and width of air switch boss more than the height of air switch boss, the length and width of described catch, described catch
Surface is provided with the mark with caveat, and described intermediate plate and catch are respectively by the intermediate plate made using transparent insulation material and gear
Piece.Air switch safety device of the present utility model can more be firmly fixed on air switch, is not substantially subject to objective bar
The impact of part, difficult for drop-off or loosening, by sheltering from the operation handle of air switch, thus avoiding other people to this air switch
Carry out maloperation, using transparent insulation material, observability is good, can be with the physical location of air switch visible in detail, that is,
Make to touch by mistake or drop to short circuit is also not result on connection joint.
Further, described intermediate plate and catch are respectively by the intermediate plate made using acrylic material and catch.Acrylic
There is insulating properties, thermoplasticity, resilience and high light transmittance, be preferable making material.
Air switch safety device of the present utility model has the advantage that
First, insulating properties: be not result in short circuit when ensureing that head wiring is abutted against in false touch；
2nd, reliability: can more be firmly fixed on air switch, substantially not affected by objective condition, be difficult
Come off or loosen；
3rd, observability: be capable of the physical location of air switch visible in detail；
4th, portability: small volume is it is easy to mass storage, carrying and use.
Brief description
Fig. 1 is the schematic diagram of this utility model air switch safety device；
Fig. 2 is that cooperation schematic diagram installed by this utility model air switch safety device；
Description of reference numerals: 1- intermediate plate；2- catch；3- resilient clamp portion；4- air switch boss.
Specific embodiment
With reference to the accompanying drawings and detailed description content of the present utility model is described in further details.
Embodiment:
Refer to shown in Fig. 1 and Fig. 2, a kind of air switch safety device, it is used for being clamped in air switch boss 4, bag
Include two intermediate plates 1, the catch 2 being connected as a single entity with side with two intermediate plates 1, the distance of described two intermediate plates 1 inner side from catch 2 to
It is gradually reduced on direction away from catch 2 thus forming resilient clamp portion 3, the distance of described resilient clamp portion 3 is opened less than air
Close the width of boss 4, the length of described two intermediate plates 1 is more than the height of air switch boss 4, the length and width of described catch 2 and sky
The length and width of air cock boss 4 match, and the surface of described catch 2 is provided with the mark with caveat, described intermediate plate 1 and catch 2
It is respectively by the intermediate plate 1 made using transparent insulation material and catch 2.
Wherein, the distance of air switch boss 4 fore-and-aft direction is the length (not shown) of air switch boss 4, empty
The distance definition of air cock boss 4 above-below direction be air switch boss 4 width, air switch boss 4 left and right directions away from
From the height being defined as air switch boss 4, the air switch of the present embodiment adopts biphase air switch, its air switch boss
4 are sized to long 55mm × wide 43mm × high 20mm.
Wherein, intermediate plate 1 and catch 2 adopt acrylic material, have insulating properties, thermoplasticity, resilience and high light transmittance, whole
Body thickness is 2～4mm, and the length of catch 2 is that 55mm is identical with the length of air switch boss 4, and the width of catch 2 is for 50mm slightly
More than the width of air switch boss 4, the length (the as overall depth of intrinsic safety full device) of intermediate plate 1 is opened more than air for 35mm
Close the height of boss 4, the distance of resilient clamp portion 3 is less than the width 43mm of air switch boss 4, using acrylic material resilience
Property produced by power block the upper and lower ends of air switch boss 4, prevent its landing or loosen.On the surface of catch 2 according to state
Mark the regulation of new safety, vertically print " No switching on, someone works " printed words of upper band red boxes using lacquer spraying technique, due to
The high light transmittance of material is made every effort to overcome in Asia, can easily observe the physical location of this air switch.Simultaneously because acrylic material is also
There is insulating properties, even if touch or drop to that short circuit is also not result on connection joint by mistake.Due to intrinsic safety full device generally hollow
Structure, can stack it is easy to mass storage, carrying and use.
Wherein, the difference according to transformer station's (current conversion station) single-phase, two-phase used in everyday and the length of three-phase air switch,
Air switch safety device of the present utility model can make respectively growth 18mm (single-phase)/55mm (biphase)/75mm (three-phase) ×
Wide tri- kinds of specifications of 50mm × depth 35mm, to meet the demand of different air switches.
Above-listed detailed description is illustrating for this utility model possible embodiments, and this embodiment simultaneously is not used to limit
Protection domain of the present utility model, all equivalence enforcements done without departing from this utility model or change, are intended to be limited solely by this case
In protection domain.
