Abstract
The present invention relates to a kind of indoor metal enclosed armoured switch cabinet arcing from opening pressure relief device.Indoor metal enclosed armoured switch cabinet arcing is from opening pressure relief device, and it includes pressure release casing and top cover；End face and the bottom surface of described pressure release casing are respectively arranged with opening；One end of one end of described top cover and pressure release box top is by hinge, and the other end of the other end of top cover and pressure release box top is fixed by plastic bolt；It is welded with U-shaped in described pressure release casing and fixes beam；Described U-shaped fixes the bottom welding of beam flash barrier.The indoor metal enclosed armoured switch cabinet arcing of the present invention is from opening pressure relief device, simple in construction, reliable in action, it is structure as a whole, can produce in advance, assemble with switch cubicle again, the shortcoming that when solving accident condition, pressure release cover plate can not be opened or can not effectively open, eliminates electrical equipment hidden peril of explosion, makes the safety of equipment and surrounding people be ensured.
Description
Technical field
The present invention relates to fixing or shifting type metal closed switch apparatus field, particularly relate to indoor metal enclosed armouring
Formula switch cubicle arcing is from opening pressure relief device.
Background technology
Indoor metal switch cabinet is once break down in inside and arcing, and inside switch cabinet pressure moment can drastically add
Greatly, at this moment need quickly to discharge pressure, extinguish electric arc, otherwise can explode；In industry, universal pressure release is in pressure release at present
Fix one piece of cover plate by plastic bolt above Kou to realize, there is potential safety hazard.
Summary of the invention
For solving above-mentioned technical problem, the invention provides indoor metal enclosed armoured switch cabinet arcing from opening pressure release
Device, solve that degree of protection is higher, releasing pressure automatically when sealing tighter switch cubicle accident time, deposit asking of big potential safety hazard
Topic.
The technical solution adopted for the present invention to solve the technical problems is: indoor metal enclosed armoured switch cabinet arcing is certainly
Opening pressure relief device, it includes pressure release casing and top cover；End face and the bottom surface of described pressure release casing are respectively arranged with opening；Described
One end of one end of top cover and pressure release box top is by the other end of hinge, the other end of top cover and pressure release box top
Fixed by plastic bolt；It is welded with U-shaped in described pressure release casing and fixes beam；Described U-shaped fixes the bottom welding of beam arc
Grid.
On described flash barrier, rule is provided with multiple 3mm width elongate strip perforate；The length of described elongate strip perforate is more than letting out
The pressure open-topped length of casing.
Described pressure release casing is rectangular shape, and it is positioned at the surface of pressure release passage window at switch cubicle top.
The bottom flange of described pressure release casing is bolted with switch cubicle top.
The two sides of described pressure release casing are provided with ventilation unit；Described ventilation unit includes dispel the heat cylindrical void or BAIYE
Window, and the inner side of ventilation unit is provided with steel wire.
Beneficial effects of the present invention: the indoor metal enclosed armoured switch cabinet arcing of the present invention opens pressure relief device certainly,
Simple in construction, reliable in action, be structure as a whole, and can produce in advance, then assembles with switch cubicle, decompression cover when solving accident condition
The shortcoming that plate can not be opened or can not effectively open, eliminates electrical equipment hidden peril of explosion, makes the safety of equipment and surrounding people obtain
Arrive guarantee.
Accompanying drawing explanation
Fig. 1 is that the indoor metal enclosed armoured switch cabinet arcing of embodiment is from the schematic diagram opening pressure relief device；

It is intended to.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples the present invention done and retouch the most in detail
Stating, this embodiment is only used for explaining the present invention, does not constitute protection scope of the present invention and limits.
Embodiment
As depicted in figs. 1 and 2, indoor metal enclosed armoured switch cabinet arcing is from opening pressure relief device, and it includes pressure release
Casing 1 and top cover 3；End face and the bottom surface of described pressure release casing are respectively arranged with opening；One end of described top cover 3 and pressure release casing
One end of 1 end face is hinged by hinge 2, and the other end of top cover 3 and the other end of pressure release casing 1 end face are solid by plastic bolt 4
Fixed；It is welded with U-shaped in described pressure release casing 1 and fixes beam 5；Described U-shaped fixes the bottom welding of beam flash barrier 6；Described arc
On grid 6, rule is provided with multiple 3mm width elongate strip perforate；The length of described elongate strip perforate is more than pressure release casing 1 open top
Length；Described pressure release casing 1 is rectangular shape, and it is positioned at the surface of pressure release passage window 8 at switch cubicle 7 top；Institute
The bottom flange stating pressure release casing 1 is bolted with switch cubicle 7 top；The two sides of described pressure release casing 1 are provided with
Ventilation unit；Described ventilation unit includes dispel the heat cylindrical void or shutter, and the inner side of ventilation unit is provided with steel wire.
The indoor metal enclosed armoured switch cabinet arcing of the present embodiment is from opening pressure relief device, internal in the state of accident
Air instantaneous expansion pressure drastically doubles, and at this moment air pressure washes plastic bolt open, and top cover was released around hinge automatic turning, pressure moment
Putting, arc light extinguishes.
The indoor metal enclosed armoured switch cabinet arcing of the present embodiment is from opening pressure relief device, and simple in construction, action can
Leaning on, be structure as a whole, can produce in advance, then assemble with switch cubicle, when solving accident condition, pressure release cover plate can not be opened or not
The shortcoming that can effectively open, eliminates electrical equipment hidden peril of explosion, makes the safety of equipment and surrounding people be ensured.
Above-described embodiment should not in any way limit the present invention, and the mode of all employing equivalents or equivalency transform obtains
Technical scheme all fall within protection scope of the present invention.
