Embodiment
As shown in Figure 1, the utility model comprises, upper terminal protection wing 1, top panel 2, front panel 3, lower panel 4 and lower terminal protection wing 5.
Top panel 2 is vertically formed in the end of upper terminal protection wing 1; Front panel 3 is formed in the ends of the top panel 2 away from upper terminal protection wing 1 in 85 degree to an angle of 90 degrees, lower panel 4 is 85 degree and is formed in front panel 3 end away from top panel 2 to an angle of 90 degrees; Lower terminal protection wing 5 is vertically formed in lower panel 4 end away from front panel 3.So just by upper terminal protection wing 1, top panel 2, front panel 3, lower panel 4 and lower terminal protection wing 5 have been in turn connected to form a convex character shape structure, after the design of convex character shape structure well can ensure that it snaps in small air circuit breaker operating handle seat, by the elasticity of material, be combined closely with small air circuit breaker, not easily loosen.
Wherein, upper terminal protection wing 1 and lower terminal protection wing 5 consistent with small air circuit breaker base height dimension, small air breaker terminals screw hole can be covered in, in regular maintenance or maintenance process, avoid the electric shock accidents touching terminal screws by mistake and cause, serve the effect of security protection.
Be formed with open side away from the side of front panel 3 between top panel 2 and lower panel 4, the side being formed with front panel 3 between top panel 2 and lower panel 4 is closed side, and wherein, open side, top panel 2, front panel 3 and lower panel 4 form trapezoidal shape successively.Distance between top panel 2 and lower panel 4 open side end is less than the height of the handle set of small air circuit breaker, distance between top panel 2 and lower panel 4 open side end 1.0mm-1.5mm less of the height of the handle set of small air circuit breaker, so just can utilize the elasticity of material, well block small air circuit breaker, make its difficult drop-off.
Simultaneously, front panel 3 and the distance between upper terminal protection wing 1 and lower terminal protection wing 5 are greater than the width 1mm of small air circuit breaker, when this width is the action of small air circuit breaker handle, the Breadth Maximum of whole small air circuit breaker, protective cover is made neither to hinder small air breaker actuation, also protective cover can not be made to protrude handle set long, so just can convenient small air circuit breaker be covered completely.
Protective cover is also formed with boundary edge 11, and boundary edge 11 is two, is left margin rib 111 and right margin rib 112 respectively.Wherein, left margin rib 111 is by the rib on the left side being formed in upper terminal protection wing 1, be formed in the rib on top panel 2 left side, be formed in the rib on front panel 3 left side, the crest line of the convex character shape that the rib being formed in lower panel 4 left side and the rib being formed in lower terminal protection wing 5 left side are in turn connected to form.Right margin rib 112 is by the rib on the right being formed in upper terminal protection wing 1, be formed in the rib on the right of top panel 2, be formed in the rib on the right of front panel 3, be formed in the rib on the right of lower panel 4 and the crest line being formed in the convex character shape that the rib on the right of lower terminal protection wing 5 is in turn connected to form.Under the mating reaction of on the left side circle rib 111 and right margin rib 112, it is made easierly to be fastened on small air circuit breaker, and effectively can reduce the friction produced with small air case for circuit breaker, thus effectively can extend the useful life of small air case for circuit breaker.
As shown in Figure 2 or Figure 3, front panel 3 is also formed with slot tag 31, slot tag 31 lower end is observation panel 32, and slot tag 31 is for inserting small air circuit breaker identification (RFID) tag.In process system normal operation, insert the system banner label of small air circuit breaker, convenient identification recognizes small air circuit breaker; When needs perform technical safety measures, disconnect process system power supply, when carrying out maintenance work, can insert " No switching on, someone works " etc. similar Remarkable Label, to remind operation and attendant to note, the pernicious injury accident that conductance of avoiding misdelivering causes.Observation panel 32 is for observing the current operating state of small air circuit breaker handle.
Slot tag 31 comprises, and is formed in the convex body 311 of top panel, and is formed in the supporter 312 on front panel 3.Wherein, the rectangle that convex body 311 is, is formed on top panel 2; Also can for be formed in the bead wire 313 of top panel 2 by multiple flange, the shape of flange can be cuboid, round point shape or other conveniently block the shape of label, to reach the effect of label upper end support.Convex body 311 and front panel 2 are formed with the first cell body, and the first cell body is used for the effect upper end of label being played to support, prevents the inclination of label and causes landing.
Supporter 312 by the horizontal supports 3121 be formed on front panel 3, and is formed in the vertical support body 3122 on horizontal supports 3121.The downward power that horizontal supports 3121 produces for supporting label, vertical support body 3122 is for preventing label owing to causing the landing after label inclination under the External Force Acting in other directions.And supporter 312 and above 3 plates are formed with the second cell body, for supporting the lower end of label, prevent dropping of label.Stable label is well stuck in slot tag 31 of coordination energy of the first cell body and the second cell body.
As shown in Fig. 4 or Fig. 5, slot tag 31 also by the horizontal support face 3141 be formed on front panel 3, and can be formed in the vertical support face 3142 on horizontal support face 3141.The height in vertical support face 3142 should be greater than the half of label height, can well prevent label from dropping; When the height in vertical support face 3142 is identical with the height of label, just form a cell body 315 with top panel 2, label can be made like this to be easy to insert this independent cell body 315.
In addition, the material of the material that the utility model adopts is transparent engineering plastics or the acrylic of good insulation preformance, effectively can avoid the electric leakage of small air circuit breaker so on the one hand, can make its smooth surface on the other hand, be convenient to clean; The current operating state more easily can observing small air circuit breaker handle from observation panel 32 of transparent material.
In a word, the utility model is stuck on small air circuit breaker, just can effectively avoids by mistake touching of operating grip.
Above, although the description of several execution mode of the present utility model, but these execution modes just propose as an example, are not intended to limit scope of the present utility model.For the execution mode that these are new, can implement in other various modes, in the scope not departing from main idea of the present utility model, various omission, displacement can be carried out and change.These execution modes and its distortion, while being contained in scope of the present utility model and main idea, be also contained in the utility model and equivalency range thereof recorded in claims.
