Abstract
The utility model discloses a kind of switchgear flip top cover, comprises top cover and hinge, it is characterized in that, edge's erecton hinge of described top cover, by hinge by cover device the top at switch cubicle, and have crossbeam at the bottom surface, edge of top cover returning apparatus, on top cover, returning apparatus has pressure-release assembly.Switchgear described in the utility model designs reversible by flip top cover by top cover for switch cabinet, need not dismantle just and can open completely, on top cover, be provided with pressure-release assembly, the arcing gas producing when fault etc. are discharged from cabinet top by this device, have ensured operating maintenance personnel's life security simultaneously.
Description
Technical field
The utility model relates to electric switch equipment, relates in particular to a kind of switchgear flip top cover.
Background technology
Low voltage switchgear generally, after manufactory has produced, takes off main bus bar independent packaging delivery before transport, delivers to after cabinet installation spelled by switchgear by user scene and refills main bus bar.The very complicated inconvenience of original main bus bar mounting means: top cover for switch cabinet must be pulled down completely, then main bus bar is penetrated to main bus bar folder from cabinet side, if on-the-spot switch cubicle lateral space, apart from inadequate or the bending injustice of bus, will make, installation is very difficult even cannot install.And electric equipment can produce great arcing gas while there is short circuit or arcing accident and cause cabinet to burst, and can have a strong impact on field apparatus administrative staff's personal safety.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is that prior art is improved, and a kind of switchgear flip top cover is provided, and the switchgear solving in current technology is installed bus difficulty, the problem wasting time and energy.
For solving above technical problem, the technical solution of the utility model is:
A kind of switchgear flip top cover, comprises top cover and hinge, it is characterized in that, edge's erecton hinge of described top cover, by hinge by cover device the top at switch cubicle, and have crossbeam at the bottom surface, edge of top cover returning apparatus.The utility model is connected to top cover on switch cubicle by hinge, the top that can open switch cubicle completely by the mode of upset, equally remove the top board of whole switch cubicle without original switch cubicle for another example, main bus bar can directly be put into main bus bar folder from cabinet top easily, install very conveniently, also save time very much, laborsaving.And the crossbeam of top lid mounted device has ensured the structural strength of top cover and whole switch cubicle, in the time that top cover is closed, the cabinet of crossbeam and switch cubicle fits tightly, in the time that top cover is opened, crossbeam is to open with top cover, is convenient to bus and directly puts into bus clip and stop without any.
Further, described top lid mounted device has pressure-release assembly, and in the time that switchgear breaks down, the arcing gas of its generation etc. are discharged from cabinet top by pressure-release assembly, have ensured operating maintenance personnel's life security.
Further, described pressure-release assembly comprises release of pressure cover plate and release of pressure passage, and described release of pressure passage is the through hole of offering on top cover, and release of pressure cover plate covers on release of pressure passage.When being short-circuited in switch cubicle or when arcing accident, the high-voltage arc gas etc. producing can be fast by release of pressure cover plate, discharge by release of pressure cover plate again, before cabinet and influenced hardly after cabinet, thereby ensure operating personnel's personal safety, accident impact has been dropped to minimum.
Further, described its edge of release of pressure cover plate is pushed down and is fixed on top cover by cover plate compressing tablet.
Further, described release of pressure side edge thereof place is provided with bending edges, strengthens exerting pressure the structural strength of cover plate with bending edges, flexural deformation after avoiding release of pressure cover plate to be subject to high-voltage arc gas impacting, effectively extend the useful life of release of pressure cover plate, reduce the maintenance cost of changing release of pressure cover plate.
Compared with prior art, the utility model advantage is:
Switchgear described in the utility model designs reversible by flip top cover by top cover for switch cabinet, need not dismantle just and can open completely, top lid mounted device has crossbeam, in the time that top cover is closed, crossbeam and switch cubicle fit tightly, ensure cabinet intensity, in the time that top cover is opened, crossbeam is opened with top cover, is convenient to bus and directly puts into bus clip and stop without any; On top cover, be provided with pressure-release assembly, the arcing gas producing when fault etc. are discharged from cabinet top by this device, have ensured operating maintenance personnel's life security simultaneously; Switchgear described in the utility model is simple in structure, easy for installation, practical, simple to operate, safe by flip top cover.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
The disclosed a kind of switchgear flip top cover of the utility model embodiment, switch cubicle top board just need not be pulled down and can open completely, and main bus bar can be easily directly be put into main bus bar folder from cabinet top, installs very conveniently, saves time, laborsaving.
As shown in Figure 1, a kind of switchgear flip top cover, comprise top cover 1 and hinge 2, edge's erecton hinge 2 of top cover 1, by hinge 2, top cover 1 is installed to the top at switch cubicle, and returning apparatus has crossbeam 5 in the bottom surface, edge of top cover 1, and crossbeam 5 can be strengthened the structural strength of top cover 1, and fit tightly with the cabinet of switch cubicle the fail safe that ensures inside switch cabinet device under top cover closed condition.
On top cover 1, device has pressure-release assembly, pressure-release assembly comprises release of pressure cover plate 3 and release of pressure passage 6, the through hole of offering on top cover 1 is release of pressure passage 6, release of pressure cover plate 3 edges are provided with the bending edges of strengthening structural strength, improve its useful life, release of pressure cover plate 3 its edges are pushed down and are fixed on top cover 1 by cover plate compressing tablet 4, and release of pressure cover plate 3 covers on whole release of pressure passage 6.
In the time using described in the utility model kind of switchgear flip top cover that bus is installed, first only need flip top cover 1 just can open the top of switch cubicle completely, then carrying out bus installation and bus clip fixes, after completing, just top cover 1 is overturn to be fastened on switch cubicle and be fixed, and then release of pressure cover plate 3 and the cover plate compressing tablet 4 of installation pressure-release assembly, finally carry out final inspection.。
Below be only preferred implementation of the present utility model, it should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection range of the present utility model should be as the criterion with claim limited range.For those skilled in the art, not departing from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
