Abstract
The utility model belongs to the field of anti-explosion electrical appliance, and particularly relates to an electrical appliance for an O area in a dangerous area. The electrical appliance comprises an explosion-proof electrical appliance body; and a safety-enhancing protective shell matched with the explosion-proof electrical appliance body is arranged at the outer side of the explosion-proof electrical appliance body. The electrical appliance provided by the utility model has the beneficial effects that a safety-enhancing protective shell is arranged on the outer side of the explosion-proof electrical appliance body, and the safety of the electrical appliance equipment in the using process can be improved; the electrical appliance has a simple structure and is easy to realize; with the intrinsic-safety detection device, the safety and reliability in the using process can be guaranteed, and the advantages of the original explosion-proof electrical appliance body, such as convenience in mounting and use, are maintained; and the safety separation fence for mounting the intrinsic-safety explosion-proof electrical appliance is not needed, and the application range of the explosion-proof electrical appliance is expanded.
Description
Technical field
The utility model relates to a kind of electrical equipment that is used for 0 district, deathtrap, belongs to the explosion-proof electric apparatus field.
Background technology
In the present circumstance, flame-proof type electrical equipment is used for 1 district, 2 districts of deathtrap, and flame-proof type electrical equipment body generally includes electric device and the outer flame-proof type shell that is provided with of electric device.Except the intrinsic safety type explosion-proof electric apparatus can be used for 0 district of deathtrap, do not have other explosion-proof lamps or explosion-proof electric apparatus and can be used for this zone, but the intrinsic safety type explosion-proof electric apparatus only limits to microelectronic circuit.During use, also want the add-on security isolated gate, this has greatly limited the installation and the use of deathtrap 0 district's equipment.
Along with the development of industries such as petrochemical industry, military project, electric equipments such as illumination, control, supervision also need be installed in the hazardous area by 0 district, so that realize the automation control of production process, satisfy the needs of the technological process of production better.
The utility model content
The technical problem that the utility model will solve is: provide a kind of simple in structure, easy for installation, and the electrical equipment that is used for 0 district, deathtrap safe in utilization.
The utility model is that the technical scheme that its technical problem of solution is adopted is: the described electrical equipment that is used for 0 district, deathtrap, comprise flame-proof type electrical equipment body, and it is characterized in that: flame-proof type electrical equipment body is provided with INCREASEDSAFETY guard shield with matching outward.
Flame-proof type electrical equipment body can be flame-proof type light fixture, flame-proof type master control electrical equipment, flame-proof type master control electrical apparatus or other flame-proof type electric device.The INCREASEDSAFETY guard shield that is complementary with it is set on the basis of flame-proof type electrical equipment, can makes whole electric equipment have the structure of double casing.When this kind electric equipment is installed on 0 district of deathtrap, because the INCREASEDSAFETY guard shield that is provided with, can the deathtrap that electric equipment belongs to environment be transformed to 1 district, 2 districts.Flame-proof type electrical equipment is installed in this zone again, can be met the standard of installing and using of GB3836 series standard and hazard place electric equipment fully, only limit to installing and using of intrinsic safety type explosion-proof electric equipment thereby thoroughly solved present hazardous environment.
On the described INCREASEDSAFETY guard shield madial wall intrinsic safety type checkout gear is set.Can be according to the corresponding intrinsic safety type checkout gear of the one-tenth component selections of different dangerous gas.In a single day the INCREASEDSAFETY guard shield seal occurs and lost efficacy, and the intrinsic safety type checkout gear can send caution immediately, guarantees that fully the built-in residing environment of flame-proof type electrical equipment is 1 district or 2 districts, guarantees use safety, reliable.
The degree of protection of described INCREASEDSAFETY guard shield is made as IP65 or IP66.The degree of protection of INCREASEDSAFETY guard shield selected for use be IP65 or IP66, can improve the fail safe that electric equipment uses.
The beneficial effect of the utility model is:
At flame-proof type electrical equipment body arranged outside INCREASEDSAFETY guard shield, can increase the fail safe in the electric equipment use, and simple in structure, realize easily; The intrinsic safety type checkout gear is set, can guarantees use safety, reliable, and keep original flame-proof type electrical equipment body installation and advantage easy to use, the required safe isolated gate of intrinsic safety type explosion-proof electric apparatus need be installed, enlarged the scope of application of flame-proof type electrical equipment.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, INCREASEDSAFETY guard shield 2, flame-proof type shell 3, light source 4, intrinsic safety type checkout gear.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described:
As shown in Figure 1; The described electrical equipment that is used for 0 district, deathtrap of the utility model comprises flame-proof type electrical equipment body, and flame-proof type electrical equipment body is an example with the flame-proof type light fixture in the diagram; The flame-proof type light fixture comprises light source 3 and is arranged on the flame-proof type shell 2 in light source 3 outsides; The INCREASEDSAFETY guard shield 1 that the 2 outer settings of flame-proof type shell are complementary with it, INCREASEDSAFETY guard shield 1 is the protection type shell of IP66 for degree of protection, and on INCREASEDSAFETY guard shield 1 madial wall intrinsic safety type checkout gear 4 is installed.
During use, the utility model is installed in 0 district of deathtrap, the formed inner space of INCREASEDSAFETY guard shield environment is equivalent to 1 district or 2 districts of traditional deathtrap; Light source 3 and flame-proof type shell 2 can be used safely in this environment; The mounting means of the utility model is identical with the mounting means of flame-proof type light fixture, and need not to increase safe isolated gate, in the use; In a single day INCREASEDSAFETY guard shield 1 seal occurs and lost efficacy; Intrinsic safety type checkout gear 4 can send caution immediately, guarantees that fully the built-in residing environment of flame-proof type electrical equipment is 1 district or 2 districts, guarantees use safety, reliable.
