Abstract
The utility model relates to a safety ventilation window for an electric cabinet, which is characterized in that the utility model is at least composed of two layers of windows, wherein the windows are arranged in inside and outside in an interval mode; ventilating holes which are arranged on a pair of adjacent windows are distributed in the ventilating direction and in a staggered mode. The utility model uses the staggered arrangement of the ventilating holes which are arranged on two layers of adjacent windows, realizes ventilation, heat rejection and safety requirements of preventing the liquid dropping, splashing and contacting electrified body, etc. The utility model has the advantage of simple structure, has the basic function of ventilation and heat rejection, and simultaneously has the functions of preventing the liquid from dropping and splashing and ensuring electrical safety, and leads the safety ventilation window for an electric cabinet to accord with a national standard.
Description
Technical field
The utility model relates to a kind of ventilating window of cabinet cabinet, is specifically related to the safe ventilation window that safe ventilation window, especially electro-medical gas tank that a kind of bin body of electric equipment adopted use cashier's office in a shop.This safe ventilation window has functions such as ventilation, water proof and anti-contact.
Background technology
Usually electric equipment at work, many electric elements all can generate heat, have in addition also be furnished with heater element.Surpass to a certain degree if temperature rises, will cause the variation of electric elements service behaviour, serious meeting damages electric elements, or causes the built-in electrical insulation decreased performance, even causes short circuit.Therefore all designs and production electric equipment all should be considered heat dissipation problem.Solve heat dissipation problem, many methods are arranged usually, but modal solution is: ventilation window is offered at bin following side and top at electric equipment.In order to improve ventilation effect, can adopt the pressure type of cooling, on ventilation window such as blower fan is installed.Yet for electric equipment, offer ventilating window and brought how to prevent that fluid drips from spattering and electric touch-safe problem again, such as, the problem of the charged electrical equipment of striking when inserting ventilating window with barred body).
GB9706.1-1995 " medical electrical equipment-first: safety general requires " has stipulated that medical electrical equipment is had following safety general requirement:
Aspect splashproof, wherein stipulate among the 2.2.20: Spurge Guard must accomplish, its shell can make that the amount of liquid that is splashed into from any direction is unlikely to influence its safe operation.So offering of ventilating window must meet this regulation.
Aspect electrical safety, wherein stipulate in the 16th chapter " shell and protective cover ": 16.a) equipment must be made and seal to such an extent that can prevent from may charged part to contact with live part with under the single failure state.And inspection method made following careful concrete regulation: by checking and referring to code test whether check meets 16a with crooked or stretch the attitude test) requirement.In addition, the hole of live part, the Kong Douyong test pin on the equipment is tested in leading to plug, connector and socket.Except land use and under free position its quality all surpass not perk of the equipment inspection of 40Kg, miscellaneous equipment all should refer to code test and test pin and insert each possible position gently.Code test refers to or tests pin must be able to not touch basic insulation, exposed live part or only make the live part of protection with varnish, enamel paint, common paper, cotton yarn, oxide-film, porcelain bead or sealant or only partly isolate with basic insulation and network source but the parts of protective earthing not.The position in any hole or size on the closure head, all must make diameter is 4mm, length is that the test bar of 100mm all during the freedom of entry vertical hanging, still can not touch live part in whole length.So offering also of ventilating window must meet these regulations.
In the prior art, the through-hole type ventilating window of common electrical mechanism of qi bin does not meet the relevant safety requirements of electric equipment.And the venetian blind type ventilating window aspect electrical safety, meets 16a substantially) requirement, but when being provided with, be unfavorable as top cover.In addition aspect antidrip spattering, be splashed at anti-any direction particularly that above-mentioned structure all can not meet the demands aspect the liquid, especially as the top cover ventilating window time, seem particularly not enough.In addition, venetian blind type aeration structure profile variant is few, be difficult to sometimes coordinate mutually with the appearance design style of cabinet cabinet, and the design variation leeway of self is also little.
Summary of the invention
The purpose of this utility model provides a kind of both simple in structure, meets electric equipment and medical electrical equipment ventilation and heat, the antidrip safe ventilation window that spatters safety requirements such as liquid and anti-contact electrification body again.
For achieving the above object, the technical solution adopted in the utility model is: a kind of electric cabinet cabinet safe ventilation window is made of inside and outside being spaced of two-layer forms, wherein at least, have set ventilation hole on a pair of adjacent forms at least, on direction of ventilation, be staggeredly arranged.
Related content in the technique scheme is explained as follows:
1, in the such scheme, for the simplified structure forms adopt inside and outside double-layer structure, set ventilation hole on inner window and the outer forms is staggeredly arranged on direction of ventilation.For two-layer forms are connected into integral body, be connected to one by a window frame between inner window and the outer forms.
2, in the such scheme, forms can be structure more than three layers or three layers from outside to inside, and wherein, set ventilation hole on ground floor forms from outside to inside and the second layer forms is staggeredly arranged on direction of ventilation.Its ventilation hole can be staggeredly arranged between remaining adjacent forms, also can not be staggeredly arranged.
3, in the such scheme, described ventilation hole can be circular hole, square hole or other geometry, as long as two-layer adjacent ventilation hole is staggeredly arranged and can achieves the goal.
4, in the such scheme, described forms are staggeredly arranged by two-layer or two-layer above shutter.
The utility model operation principle is: utilize the dislocation of set ventilation hole on the two-layer adjacent forms to arrange, realize both ventilation and heat, can antidriply spatter safety requirements such as liquid and anti-contact electrification body again.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, the utility model is simple in structure, implements easily, but both had the basic function of ventilation and heat on function, also has the antidrip function of spattering and guaranteeing electrical safety simultaneously, has that rod is slotting not to be advanced, and the antidrip effect of spattering of water is arranged.
2, the utility model meets 2.2.20 and 16a among the GB9706.1-1995) requirement, satisfy in GB9706.1-1995 " medical electrical equipment-first: the safety general require " regulation safety general requirement to medical electrical equipment.
3, the utility model is simple for structure, and is elegant in appearance, easy to make, economical and practical.
4, the utility model in appearance, also the design for electric cabinet cabinet ventilating window provides more variation, and ventilating window design and electric cabinet cabinet style and style are coordinated more with attractive in appearance.
