Abstract
The invention provides a fireproof insulated casing for an isolation transformer. The fireproof insulated casing comprises a box-type metal casing of which the bottom is opened and sealing terminals connected to two sides of the outside of the casing by using screws, wherein air-drying insulating paint is uniformly smears on the outside surface of the casing; an air-drying insulating paint layer, an inorganic ceramic fiber paper layer, a bonding agent layer and a flame-retardant insulating material layer are also sequentially arranged inside the casing. The fireproof insulated casing provided by the invention has the beneficial effects that the insulating performance of the isolation transformer is enhanced, so that iron loss and copper loss are reduced, and the ignition and explosion of the transformer caused by overheat are prevented; due to the adoption of the casing made of a fireproof material, the ignition is prevented; from two aspects of insulation and ignition prevention, the casing with fireproof performance and good insulating performance for the isolation transformer is provided.
Description
Technical field
The invention belongs to transformer equipment field, especially relate to a kind of fire-proof insulation shell of isolating transformer.
Background technology
The Main Function of isolating transformer makes the electric current of former limit winding and vice-side winding both sides form electrical isolation, for electrical appliance provides " safety power supply ", also utilize iron core to play one " filtration " effect for the effect that the consumption of power supply high frequency waves is large simultaneously, for electrical appliance provides pure power supply, but the iron loss of isolating transformer itself and copper loss can be heat energy small part electric energy conversion, temperature in the transformer course of work is raised, have the hidden danger of Fire explosion, the good isolating transformer of insulation property can effectively reduce iron loss and copper loss, isolating transformer on the market is only focused on from source---improve insulation property, in order to protect the harm of Fire explosion, ignore and promote the fire protecting performance of isolating transformer own.
Innovation and creation content
The problem to be solved in the present invention is to provide a kind of shell of isolating transformer not only having had fire protecting performance but also had good insulation property.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of fire-proof insulation shell of isolating transformer, it is characterized in that: comprise the cell type metal shell of bottom opening and utilize screw to be connected to the hermetic terminal of described housing exterior both sides, described housing exterior surface evenly scribbles air-dried insulating paint, and described enclosure is also provided with air-dried insulating paint layer, inorganic ceramic fiber paper layer, adhesive phase and flame-retardant insulating material layer successively.
Further, described flame retarding material is nano environmental protection bittern-free flame-proof material layer.
Further, the terminal lead-out wire of described hermetic terminal is coated with laminated polyester film.
Further, described shell is formed by metal glass steel Plate Welding.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, by the shell of metal glass steel Plate Welding, the mechanical strength of isolating transformer itself is made to be enough to tackle the different installation environment such as field or city electricity consumption, inorganic ceramic fiber paper layer is as the substrate layer of enclosure, ceramic fibre is not only prevented fires but also insulate, and itself is very thin, cost is low, do not take up space, Nanometer environmental-protechalogen-free halogen-free fire-retardation insulation material layer is as the outermost layer of the inside of shell, nanostructure is tightly compact, superior flame retardant property under the prerequisite of insulation, nontoxic, security performance is high, the terminal lead-out wire of hermetic terminal is coated with laminated polyester film, heat-resisting, insulation, heat conduction and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure:
1, shell; 2, hermetic terminal; 3, terminal lead-out wire.
Embodiment
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
As shown in Figure 1, the invention provides a kind of fire-proof insulation shell of isolating transformer, comprise the cell type metal shell 1 of bottom opening and utilize screw to be connected to the hermetic terminal 2 of described shell 1 both sides external, the outer surface of described shell 1 evenly scribbles air-dried insulating paint, and described shell 1 inside is also provided with air-dried insulating paint layer, inorganic ceramic fiber paper layer, adhesive phase and flame-retardant insulating material layer successively.
Described flame retarding material is nano environmental protection bittern-free flame-proof material.
The terminal lead-out wire 3 of described hermetic terminal 2 is coated with laminated polyester film.
Described shell 1 is formed by metal glass steel Plate Welding.
The course of work of this example: when using of the present invention, shell 1 is formed by metal glass steel Plate Welding, the mechanical strength of isolating transformer itself is made to be enough to tackle the different installation environment such as field or city electricity consumption, air-dried insulating paint is applied to shell 1 inner surface and outer surface, using the substrate layer of inorganic ceramic fiber paper layer as shell 1 inside, using the outermost layer of Nanometer environmental-protechalogen-free halogen-free fire-retardation insulation material layer as the inside of shell 1, by coated for the terminal lead-out wire 3 of hermetic terminal 2 upper laminated polyester film.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
