The patent No. is that ZL201420258509.1 discloses a kind of switchgear flip top cover, edge's erecton hinge of described top cover, by hinge by the top of cover device at switch cubicle, and have crossbeam at bottom surface, the edge returning apparatus of top cover, on top cover, returning apparatus has pressure-release assembly.Top cover for switch cabinet is designed reversible by described switchgear flip top cover, need not dismantle and just can open completely, top cover is provided with pressure-release assembly, the arcing gas produced during fault etc. are discharged from cabinet top by this device, have ensured the life security of operating maintenance personnel simultaneously.But this structure is more closed to switch cubicle, air-flow conduction property is poor, easy accumulated temperature, and convertible top cover for switch cabinet is also only in maintenance or just manual unlocking when needing.
Utility model content
The utility model object is for the deficiencies in the prior art, there is provided a kind of switchgear Novel belt ventilating opening convertible top cover, the thermovent that this equipment is arranged by flip top cover, the problems such as the switch cubicle installation effectiveness solving prior art is low, heat dispersion difference.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model provides a kind of switchgear Novel belt ventilating opening convertible top cover, comprise the switch cubicle top board that middle part has release of pressure port, be fixed on the cabinet crossbeam on the side of switch cubicle top board bottom surface and hinges, by the release of pressure passage cover plate on cover plate compressing tablet fixed switchgear top board, described release of pressure passage cover plate upper surface is provided with ventilating blind mouth.
Further, described switch cubicle top board and distribution cabinet realize reversible articulated structure by two hinges, described hinges is high strength hinge, switch cubicle top board is also fixed with pressure relief device, the installation of main bus bar is completed when not needing dismounting top board, improve installation effectiveness, avoid because being short-circuited in switch cubicle or arcing accident, the high-voltage arc gas etc. produced, can quickly through pressure release passage, discharged by top board pressure relief device again, before cabinet and influenced hardly after cabinet, thus ensure that the personal safety of operating personnel and accident impact dropped to minimum.
Further, described ventilating blind mouth is arranged by longitudinal six rows, the laterally modes of three rows on release of pressure passage cover plate, roof pressure releasing device is equipped with heat dissipation ventilation multivane mouth, effectively prevent cabinet inside and produces amount of heat, having good economy because not needing to consume additional energy source.
Further, described cabinet crossbeam is " U " type channel bar or square groove part, adopts screw or bolt with the fixed form of switch cubicle top board, and when switch cubicle top board is closed, cabinet crossbeam and switch cubicle are combined closely, and ensures cabinet intensity; When top board is opened, cabinet crossbeam is opened with switch cubicle top board, is convenient to when bus directly puts into bus clip without any stop.
The utility model has following beneficial effect:
1, the utility model is by being set as reversible structure by switch cubicle top board, and main bus bar directly can put into main bus bar folder easily from cabinet top, have installation more convenient and quicker, can save a large amount of time and cycle, substantially increase efficiency.
2, the utility model is by switch cubicle mounting of roof plate girth member, strengthens the structural strength of switch cubicle top board, and at the heat dissipation ventilation multivane mouth that switch cubicle top board is provided with pressure relief device and matches, effectively prevent cabinet inside and produce amount of heat.
Certainly, implement arbitrary product of the present utility model might not need to reach above-described all advantages simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, be briefly described describing the required accompanying drawing used to embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the convertible top cover of a kind of switchgear of the utility model Novel belt ventilating opening;
In accompanying drawing, the list of parts representated by each label is as follows:
1-switch cubicle top board, 2-hinges, 3-release of pressure passage cover plate, 4-cover plate compressing tablet, 5-cabinet crossbeam, 6-release of pressure port, 301-ventilating blind mouth.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to shown in Fig. 1, the utility model is the convertible top cover of a kind of switchgear Novel belt ventilating opening, comprise the switch cubicle top board 1 that middle part has release of pressure port 6, be fixed on the cabinet crossbeam 5 on the side of switch cubicle top board 1 bottom surface and hinges 2, by the release of pressure passage cover plate 3 on cover plate compressing tablet 4 fixed switchgear top board 1, described release of pressure passage cover plate 3 upper surface is provided with ventilating blind mouth 301.
